Commercial Landlord Insurance Explained

Why your tenant's insurance doesn't protect your building — and what does.

Who this is for

Who This Guide Is For

  • Commercial property owners with 1–20+ buildings (strip malls, office buildings, industrial, mixed-use) who want to understand what their policy actually covers
  • Real estate investors who own commercial property and lease it to business tenants — and need to know where their insurance stops and the tenant’s begins
  • Property management companies handling insurance compliance for commercial landlords and tenant COI verification
  • Building owners reviewing policies at renewal and wondering whether they’re actually protected against the risks they face every day

Case Study: 95,000 sq ft Multi-Tenant Complex — 22% Renewal Halted at Sign-Off

Commercial landlord renewal review — leases and tenant certificates matched against the current policy before sign-off

Building Owner Scenario

OPERATOR SCENARIO

OPERATOR

Scenario

Owner of a ~95,000 sq ft multi-tenant retail/office complex (TIV ~$8M, eight tenants including a restaurant and a medical office) receives a renewal proposal 22% over the expiring year. The owner's asset manager flags it for review before sign-off.

Loss-of-rents limit unchanged for four years. Rents have risen approximately 30% across the rent roll during that window. Two tenant COIs lapsed without the property manager catching the gap. Building insured near purchase price, not replacement cost. Ordinance-or-law coverage limit set at original underwriting and never re-evaluated.

The current broker's renewal proposal is silent on the rent roll growth, silent on the COI lapses, silent on the construction-cost inflation. The 22% increase is presented as a market-driven adjustment to the same coverage structure that's been auto-rolling for four cycles.

What we did

Read all eight leases and cross-checked tenant COIs against the underlying lease insurance requirements. Identified the two lapsed COIs and the three additional COIs missing the lease-required additional-insured language. Re-priced the building to current replacement cost using current construction cost data for the market — surfaced approximately 28% under-insurance against current rebuild cost. Re-sized loss-of-rents to 14 months of current rent roll (matched to a realistic rebuild timeline for a building of this construction class). Added equipment-breakdown coverage for the shared HVAC and elevators. Added a vacancy endorsement covering an upcoming unit turnover the lease office had flagged.

🎯 The Outcome

Bound a program matched to actual lease obligations rather than auto-rolling the prior structure. Closed the replacement-cost gap before any covered loss could expose it. Brought the two lapsed tenant COIs into compliance and corrected the three with non-compliant additional-insured language. The building owner approved a rebuilt program at renewal — not a rubber-stamp on a 22% increase to coverage that didn't reflect the building's current rent roll, current construction costs, or current lease obligations.

Core Coverage

The Eight Lines Every Commercial Building Owner Carries

Most commercial building owners carry a basic property policy and GL. A fully-built program carries all eight lines below — each one tied to what the leases, the tenant mix, and the current rent roll actually demand. For an overview, read our guide on Commercial Landlord Insurance: What Owner Policies Skip.

01

🏢

Commercial Property Policy (Lessor’s Risk form)

What it covers: Buildings, structures, common areas, shared mechanical, owner-controlled improvements. Tenant-improvement-and-betterment treatment depends on lease language. Limits: 100% of current replacement cost — not market value, not loan balance, not purchase price. The question this answers when something goes wrong: When a covered loss exceeds your replacement cost limit, where does the gap come from — owner reserves, lender renegotiation, or a partial-rebuild that triggers ordinance-or-law gaps?

02

💰

Loss of Rents (Business Income for Landlords)

What it covers: Replacement of rental income when the building is untenantable after a covered loss. Coverage period typically 12-24 months. Limits: Annual rent roll × coverage period elected. The question this answers: When a fire takes the building offline tomorrow, does your loss-of-rents limit reflect today’s rent roll — or last underwriting’s rent roll from before your renewal increases?

03

🛡️

General Liability

What it covers: Third-party bodily injury and property damage on building common areas. Slip-and-falls, parking lot incidents, structural injuries to visitors. Limits: $1M per occurrence / $2M aggregate minimum. Higher for buildings with restaurant or medical tenants. The question this answers: When a third party is injured on common area and the claim exceeds primary GL, what’s the layer above — umbrella, building owner assets, or both?

04

🔧

Equipment Breakdown

What it covers: HVAC, electrical, plumbing, elevators, boilers, chillers — the shared mechanical systems standard property policies treat as wear-and-tear exclusions. Limits: Building-specific, typically aligned to TIV. The question this answers: When a chiller fails mid-summer or an elevator goes down for two weeks, does the policy fund the repair AND the rent abatement to affected tenants — or does the standard property policy exclude the loss entirely?

05

🚪

Vacancy Coverage

What it covers: Maintains property + liability coverage during tenant turnover periods that exceed the standard vacancy clause threshold (typically 60 days). Limits: Endorsement adjusts the standard vacancy clause. Coverage period and conditions specified in endorsement language. The question this answers: When a tenant moves out and the unit sits for 90 days during build-out for the next lease, does your property policy still respond to a covered loss — or has the vacancy clause already eliminated coverage by the time the loss happens?

06

🌊

Water Backup & Sewer

What it covers: Damage from water or sewer backup through drains and pipes that the standard property policy excludes. Common multi-tenant building exposure given shared plumbing systems. Limits: Endorsement-specific. Typically expressed as a sub-limit ($25K-$500K range depending on building). The question this answers: When a tenant’s improperly-flushed item backs up through the building’s shared sewer line and damages multiple ground-floor units, does your policy respond — or does the standard exclusion leave the building owner exposed for the rebuild and the affected tenants’ rent abatement?

07

🏛️

Ordinance or Law

What it covers: Demolition costs for undamaged portions, increased construction costs to meet current code, and the loss of value on the undamaged portion when partial rebuild is forced. Limits: Typically expressed as a percentage of building limit (Coverage A) plus a dollar amount (Coverage B + C). The question this answers: When a covered loss to a 30-year-old building triggers current building code compliance on the rebuild, does your policy fund the code-driven gap — or does the building owner cover the difference?

08

Umbrella / Excess Liability

What it covers: Additional limits above GL and other primary liability policies. Layers over the entire program. Limits: Building value plus one year’s rent roll at minimum. The question this answers: When primary GL limits exhaust on a catastrophic claim, does the umbrella respond — or does the gap become a building owner exposure event?

Section summary

Eight policy lines carry most commercial building owner exposure: commercial property, loss of rents, general liability, equipment breakdown, vacancy coverage, water backup, ordinance or law, and umbrella. Which limits each one carries depends on what your leases, your tenant mix, and your current rent roll demand — not what the prior broker quoted.

Building owners who don't have coverage surprises aren't the ones whose carrier said yes fastest — they're the ones whose agent read the leases first.

Critical Knowledge

Tenant Insurance Doesn't Protect Your Building

This is the most misunderstood concept in . Your tenants have insurance. You have insurance. But the two policies are designed to protect different things — and the gap between them is where six-figure losses happen.

What Your Tenants’ Insurance Does NOT Cover

  • ×Your building structure
  • ×Your common areas, parking lot, and exterior
  • ×Your loss of rental income
  • ×Damage caused by your building systems to their property

What Your Tenants’ Insurance DOES Cover

  • Their business personal property (inventory, equipment, furniture)
  • Their business liability (customers injured inside their space)
  • Their loss of business income if they can’t operate

The Critical Gap

If a pipe bursts in your tenant's ceiling and destroys their inventory, whose insurance pays? The answer surprises most landlords: both will initially deny. The tenant's insurer says “the landlord's building caused the damage.” The landlord's insurer says “the tenant is responsible for their own property.” This is why lease language matters as much as policy language — and why most commercial leases have insurance gaps that nobody catches until there's a claim.

Lease Insurance Requirements Every Commercial Landlord Needs

1. Tenant GL with Specific Minimum Limits

Require tenants to carry GL with at least $1M/$2M limits. Higher-risk tenants (restaurants, auto shops) should carry $2M/$4M.

2. Landlord Named as Additional Insured

Your entity must be listed as an additional insured on the tenant’s GL policy. This extends their coverage to you for claims arising from their operations.

3. Primary and Non-Contributory Language

The tenant’s policy must pay first on any claim. Your policy should never contribute to claims arising from the tenant’s operations.

4. Waiver of Subrogation

The tenant’s insurer agrees not to pursue you for damages it has paid. Without this, the tenant’s insurer can sue you after paying a claim.

5. COI Before Occupancy and at Every Renewal

Require a Certificate of Insurance before the tenant moves in and updated certificates annually. Don’t accept move-in without verified coverage.

6. 30-Day Notice of Policy Cancellation

The tenant’s carrier must notify you if the policy is cancelled or non-renewed. Without this, you won’t know when a tenant loses coverage.

When was the last time someone actually verified your tenants' against these requirements? Most commercial landlords find out about the gap only when there's a claim.

For a deeper understanding of how works alongside tenant policies, read our guide on Commercial Landlord Insurance: What Owner Policies Skip.

Section summary

Tenant insurance protects the tenant’s property and tenant’s liability — not the building’s structure, , or rent stream. The gap between what the tenant’s policy covers and what the building owner is exposed to is what the lease insurance schedule and the building’s own commercial property policy exist to close.
Avoid These Pitfalls

The 8 Mistakes Commercial Landlords Make With Insurance

These are the coverage gaps and process failures we see repeatedly across hundreds of commercial landlord policy reviews. Each one is preventable. Each one has cost a building owner real money.

1

📊 Does your policy know the difference between a $200K tenant and a $5M tenant?

Not all tenants create equal risk. A medical office generating $5 million in revenue creates different liability exposure than a small accounting firm generating $200,000. A restaurant tenant with deep fryers and grease hoods creates different property risk than a retail boutique. Yet most commercial landlord policies treat all tenants the same — the premium and coverage don’t reflect the actual risk profile of your tenant mix. High-risk tenants like restaurants, auto repair shops, and manufacturing businesses should trigger higher coverage limits and specific endorsements. If your policy doesn’t account for tenant type, it’s probably not covering the actual risk.

How to fix this: Provide your agent with a tenant roster that includes business type, revenue (if known), and lease terms for each tenant. Ask them to review whether your GL limits, property coverage, and endorsements reflect the actual risk created by each tenant’s operations.

A medical suite, a deep-fryer restaurant, and a quiet accounting office don’t create the same property or liability exposure — yet many programs rate and cover them as if they did. The question worth asking before your next renewal: does your current policy reflect the actual risk each tenant brings to the building, or is it carrying the same limits and endorsements it would for any tenant in any space?

2

🏢 When was the last time you read what your tenants’ insurance actually covers?

Most landlords require tenants to provide a Certificate of Insurance at lease signing and never check it again. But a COI is a snapshot in time — it proves the tenant had insurance on the day it was issued. It doesn’t prove they still have it. Policies get cancelled for non-payment, limits get reduced at renewal, and endorsements get dropped. If your tenant’s policy lapsed three months ago and their customer slips inside the space, the claim comes to your GL policy. Your premiums go up. Your tenant’s lapsed insurance becomes your problem.

How to fix this: Implement an annual COI verification process. Require every tenant to provide an updated COI at least 30 days before their policy renewal date. Verify that limits, additional insured status, and waiver of subrogation are current. Your property manager should track this for every tenant.

Across the multi-tenant buildings our team reviews, a significant share carry tenant COIs that don’t match the underlying lease requirements — wrong additional-insured language, missing waiver of subrogation, expired certificates, or coverage limits below what the lease demands. The question your office should be able to answer: when did your team last audit your tenants’ COIs against the leases — not at lease signing, but as the policies have renewed since?

3

🚪 What happens when a unit sits empty for 60 days?

This is the gap that catches more commercial landlords than any other. Standard commercial property policies include a vacancy clause that eliminates coverage for water damage, theft, vandalism, and sprinkler leakage after 60 consecutive days of vacancy. The policy doesn’t warn you when you cross the 60-day mark. There’s no notification. You simply lose coverage — and you won’t know until you file a claim and it’s denied. In multi-tenant buildings, the clause typically applies per-unit, not per-building. So if one of four units is vacant for 90 days, the vacancy exclusion applies only to that unit.

How to fix this: Add a vacancy permit or vacancy endorsement to your policy before any unit crosses the 60-day mark. Notify your carrier immediately when a tenant moves out. Track vacancy duration for every unit. The cost of the endorsement is a fraction of a denied claim.

Vacancy provisions in most commercial property policies reduce or eliminate coverage when units sit unoccupied beyond a defined period — typically 60 days. The question worth asking before any tenant turnover: does your policy carry a vacancy endorsement that maintains coverage during the gap between leases, or does the standard vacancy clause expose the building to denial of a covered loss claim?

4

📋 Does your tenants’ insurance actually meet the requirements in your lease?

Your lease likely specifies that tenants must carry GL with $1M/$2M limits, name you as additional insured, include waiver of subrogation, and maintain primary/non-contributory language. But have you ever actually verified that the tenant’s policy matches these requirements? A COI shows coverage exists — it doesn’t prove the endorsements are in place. Many tenants buy the cheapest policy available and assume it’s compliant. It’s often not. And when a claim hits and the tenant’s policy doesn’t match what the lease requires, the landlord’s policy becomes the backstop.

How to fix this: Don’t just collect COIs — read them. Verify that the certificate holder name matches your entity exactly. Confirm additional insured and waiver of subrogation endorsements are listed. Check that limits meet or exceed your lease requirements. If anything is missing, require correction before the tenant takes occupancy.

An injury or property-damage claim involving an uninsured tenant contractor on common areas typically defaults to the building’s GL policy. The claims history that follows can drive renewal premium increases for years. The question worth asking: does your lease require tenants to enforce vendor COI compliance — and does your property manager verify that enforcement before any tenant contractor steps on building common areas?

5

💸 If your biggest tenant leaves tomorrow, does your policy replace the rent?

Loss of rents coverage protects your rental income when a covered loss (fire, storm, etc.) makes the building uninhabitable. But it only covers income lost due to insured perils — it doesn’t cover a tenant simply leaving. That said, most landlords don’t carry enough loss of rents coverage even for covered losses. If a fire requires more than a year of reconstruction, the loss of rents limit has to cover every month the building sits offline. Many landlords carry only six months — leaving a gap that means paying the mortgage out of pocket while the building is being rebuilt.

How to fix this: Calculate 12–18 months of gross rental income and set your loss of rents limit accordingly. Review this annually as rents increase. If you have a building under renovation or have recently signed higher-rent leases, update your coverage immediately.

Loss-of-rents limits across most multi-tenant buildings haven’t been re-rated against current rent roll since the original underwriting. Rents rise; the limit doesn’t. The question worth asking: if a fire took the building offline tomorrow, would your loss-of-rents limit cover 12-18 months of current rent — or 12-18 months of rent from three or four years ago?

6

🔧 Who pays when the HVAC or elevator fails?

Standard commercial property policies cover damage from fire, wind, hail, and other named perils. They do not cover mechanical or electrical breakdown of building systems. If your commercial HVAC unit fails, your elevator motor burns out, or your boiler cracks, the repair bill comes out of your pocket unless you have equipment breakdown coverage (sometimes called boiler and machinery). For commercial buildings with aging systems, a single HVAC failure or elevator motor burnout can run well into five figures. These are maintenance realities that happen every year.

How to fix this: Add equipment breakdown coverage to your commercial property policy. It covers mechanical and electrical failure of building systems, and the annual cost depends on the number and age of systems. Compare that to the cost of a single HVAC replacement.

A meaningful share of commercial building owners don’t carry equipment breakdown coverage on their property programs. When a chiller fails mid-summer or a boiler ruptures mid-winter and the standard property policy excludes the loss as wear-and-tear or mechanical breakdown, the repair costs and the loss-of-rents from tenant impact land on the building owner. The question worth asking: does your current property policy carry equipment breakdown — or does it exclude the systems most likely to fail?

7

💵 Is your building insured for replacement cost or purchase price?

This is one of the most expensive errors in commercial landlord insurance. Many building owners set their policy limits based on what they paid for the property, what the bank appraised it for, or what the tax assessor values it at. None of these reflect what it would actually cost to rebuild the building today. Construction costs have risen materially across many markets in recent years. A building purchased several years ago can cost substantially more to rebuild today. If your policy covers the old purchase price and the building is destroyed, you’re short the difference — and you’re still paying the mortgage on a building that no longer exists.

How to fix this: Get an independent replacement cost appraisal every 3–5 years. Don’t rely on your carrier’s estimate, your tax assessment, or your purchase price. Apply an inflation guard endorsement (3–5% annually) between appraisals to keep pace with construction cost increases.

Buildings insured at purchase price or original loan amount carry the full rebuild gap as owner exposure. Construction costs across most commercial markets have risen materially since the building was first underwritten. The question worth asking at every renewal: is your property limit set against current rebuild cost, or against an appraisal from before the cost curve moved?

8

⚠ Have you ever had a professional review every lease against your insurance policy?

Your leases contain insurance obligations — both what you’re required to carry and what your tenants are required to carry. Your insurance policy contains its own terms, conditions, and exclusions. These two documents need to align. If your lease promises tenants that you’ll carry $2M in GL but your policy only covers $1M, you’re in breach. If your lease requires tenants to carry additional insured endorsements but your property manager never verifies, you’re exposed. Most commercial landlords have never had a professional compare their leases to their insurance side by side.

How to fix this: Before your next renewal, give your insurance agent copies of every active lease. Ask them to identify any gap between what the lease requires and what the policy provides. This comparison takes about an hour per property and prevents six-figure problems.

Boards and property managers who actively review renewal proposals line-by-line against the expiring declarations consistently find changes the carrier made without highlighting them: reduced limits, added exclusions, increased deductibles, removed endorsements. The question worth asking: when was the last time your office did this review at renewal — instead of relying on the broker’s auto-roll?

Section summary

Most commercial landlord coverage gaps trace back to the same handful of mistakes: limits set to purchase price instead of replacement cost, never re-rated against current rent roll, tenant COIs never audited against lease requirements, vacancy endorsements missing, and renewals that auto-roll without anyone reading what changed.

Before the next renewal

Most commercial property programs are renewed against last year's declarations — without anyone reading the leases.

We pull your leases, match coverage requirements line-by-line against the current policy and the tenants' COIs, and surface the gaps before the next renewal — not after a tenant claim, a vacancy denial, or a lender certificate request.

By State

State-Specific Considerations

Commercial landlord insurance requirements and pricing vary significantly by state. Local building codes, natural disaster exposure, and tenant law all affect what coverage you need and what it costs. Here are a few notable examples:

California

Strict lease law requirements and high property values drive higher premiums. Earthquake coverage is often necessary but excluded from standard policies — it requires a separate policy through the California Earthquake Authority or a surplus lines carrier. Wildfire exposure in expanding urban-wildland interface zones adds further complexity. California also has some of the strongest tenant protection laws in the country, making lease insurance compliance critical. California commercial landlord insurance

Texas

Generally landlord-friendly state laws, but wind and hail exposure in eastern and coastal regions significantly affects property insurance pricing. The growing commercial real estate market in Dallas, Houston, Austin, and San Antonio means more building owners entering the market who need guidance on commercial landlord coverage. Named storm deductibles along the coast can be 2–5% of the building value. Texas commercial landlord insurance

Colorado

Mountain region risks including hail, wildfire, and snow load affect commercial property pricing. The Denver metro commercial boom has increased property values and replacement costs significantly, making accurate valuations critical. Colorado's construction defect laws also affect landlords who are renovating or building new commercial properties. Colorado commercial landlord insurance

New Jersey

High property values, strict building codes, and hurricane exposure on coastal properties create unique insurance challenges. Older commercial buildings in urban areas often require specialized coverage for aging infrastructure. The state's dense commercial real estate market means vacancy rates and tenant quality are critical factors in coverage decisions. New Jersey commercial landlord insurance

Common Questions

Frequently Asked Questions

How much landlord insurance do I actually need?
The amount of commercial landlord insurance you need depends on three factors: the replacement cost of your building (not market value or purchase price), the total rental income you need to protect, and the lease requirements you’ve committed to with your tenants. Start with a replacement cost appraisal — this tells you what it would cost to rebuild your building at today’s construction prices. Then add loss of rents coverage equal to 12–18 months of gross rental income. Finally, review your leases to confirm your GL limits meet or exceed what you’ve promised tenants. Most commercial landlords are underinsured because they set their limits based on purchase price or assessed value, which routinely fall short of actual replacement cost.
What’s the difference between landlord insurance and commercial property insurance?
Commercial landlord insurance (technically a Lessor’s Risk Only form) is a specific type of commercial property insurance designed for building owners who lease space to tenants. Standard commercial property insurance is designed for owner-occupied buildings where the policyholder uses the building for their own business operations. The key difference is that the Lessor’s Risk form is built around the unique risks of being a landlord: tenant-caused damage, vacancy exposure, loss of rental income, and the liability that comes with common areas. A standard commercial property policy won’t include loss of rents coverage, won’t address vacancy clauses properly, and won’t account for the tenant/landlord liability split.
Does my tenant’s insurance protect my building?
No. Your tenant’s insurance protects their business — their inventory, their equipment, their liability to customers, and their business income. It does not cover your building structure, your common areas, your loss of rental income, or your liability as a property owner. Even when your lease requires the tenant to carry insurance, that insurance is designed to protect the tenant, not the landlord. The only way your tenant’s policy provides any protection to you is if your lease requires them to name you as an additional insured on their GL policy — and even then, it only covers claims arising from the tenant’s operations, not building-level issues.
What happens if a unit is vacant for more than 60 days?
Most commercial property policies include a vacancy clause that significantly reduces coverage after a unit has been vacant for 60 consecutive days. Specifically, coverage for water damage, theft, vandalism, sprinkler leakage, and glass breakage is typically excluded entirely. Other covered perils may have their payouts significantly reduced. This clause exists because vacant buildings have higher risk — no one is there to notice a burst pipe, a break-in, or a fire. To maintain full coverage during vacancy, you need a vacancy permit or vacancy endorsement added to your policy before the 60-day mark. This costs extra but is far cheaper than an uncovered loss.
How do I know if my loss of rents coverage is enough?
Calculate your total gross rental income across all units, then multiply by the number of months it would realistically take to rebuild your building after a total loss. For most commercial properties, this means 12–18 months of gross rent. Many landlords carry only six months, which leaves them paying the mortgage out of pocket for the remaining months while the building is rebuilt. Re-rate the limit against your current rent roll at every renewal — rents rise, and a limit set at the last underwriting drifts out of date. Remember: loss of rents doesn’t cover voluntary vacancy or tenant non-payment — only income lost due to a covered property loss.
Do I need separate policies for each property I own?
Not necessarily. If you own multiple properties, you can often bundle them under a single commercial property policy (sometimes called a blanket policy or a schedule of locations). This has advantages: simplified administration, potential premium discounts, and blanket coverage that can shift limits between properties if one has a larger-than-expected claim. However, each property still needs to be properly valued and listed on the policy. The risk of bundling is that if your total insured value is too low across all properties, you may face coinsurance penalties at claims time. Work with an agent who understands multi-property portfolios to structure this correctly.
What’s the difference between replacement cost and actual cash value?
Replacement cost pays what it costs to rebuild or repair your building with materials of like kind and quality at today’s prices. Actual cash value (ACV) deducts depreciation — so an aging roof at the end of its useful life pays out a fraction of replacement cost. For commercial landlords in the $1M-plus multi-tenant range, the difference can be catastrophic: a building bought years ago can cost materially more to rebuild today than its purchase price. If your policy covers replacement cost, the rebuild is funded. If it covers ACV, depreciation can leave a six-figure gap. Always insure commercial buildings at replacement cost.
Who’s responsible when a tenant’s equipment damages my building?
This is one of the most contested areas of commercial landlord insurance. If a tenant’s equipment (like a restaurant’s grease trap or a manufacturer’s machinery) damages your building, the answer depends on your lease language and both parties’ insurance. Your property policy covers the building damage. The question is whether your insurer will then subrogate (seek reimbursement) against the tenant. If your lease includes a mutual waiver of subrogation, your insurer can’t pursue the tenant — which keeps the landlord-tenant relationship intact but means your claims history takes the hit. Without a waiver, your insurer may sue the tenant, creating a hostile relationship. Get this right in the lease before it matters.
Why do my tenants need to name me as additional insured?
When your tenant names you as an additional insured on their GL policy, it means their policy extends coverage to you for claims arising from the tenant’s operations. If a customer slips inside the tenant’s space and sues both the tenant and the landlord (which is common), the tenant’s GL policy covers both parties. Without additional insured status, only the tenant is covered, and the landlord has to rely on their own GL policy — which hits your claims history and can increase your premiums at renewal. Additional insured status is standard in most commercial leases, but many landlords never verify that their tenants have actually added the endorsement.
What documents do I need to get a commercial landlord insurance quote?
To properly quote a commercial landlord, your agent needs: (1) property address, square footage, and construction type for each building, (2) current lease agreements showing tenant types and rental income, (3) current policy declarations page (if you have existing coverage), (4) loss run history (3–5 years), (5) building age, renovation history, and major systems (HVAC, roof, plumbing, electrical), (6) vacancy history and current occupancy rates, and (7) protective features (sprinklers, fire alarms, security). If an agent quotes you without asking for at least items 1, 2, and 4, they’re guessing. At Insurance Service 365, we require your leases before we’ll issue a proposal because the coverage has to match what your leases require.
Our Process

We Review Your Leases Before You Bind

Insurance Service 365 commercial landlord policy review process — reviewing leases, tenant COIs, and coverage gaps before binding

Most insurance agents quote commercial landlords based on a property questionnaire: square footage, construction type, age, done. They never see the leases that dictate your actual insurance obligations. We do it differently. Before we issue a proposal, we read your leases. We cross-check your tenants' COIs against your lease requirements. We identify gaps between what your lease says you must carry and what your policy actually provides.

Then we present our findings to you on a video call, in plain English. No jargon, no pressure — just a clear explanation of where your building owner coverage stands, where the gaps are between your leases and your policy, and what your options are. This is what we call a consultative review, and it's included at no cost for every commercial landlord client.

It's also why building owners who work with us rarely discover coverage surprises at claims time. When we say your policy matches your lease obligations, it does — because we've read both.

See exactly what a lease-to-policy comparison looks like — from lease analysis to tenant COI verification to coverage recommendation — in under 10 minutes.

This consultative approach is the same process we bring to contractor insurance for tenant buildouts and property improvements and HOA insurance for mixed-use properties with residential components. For buildings with food service tenants, we also handle restaurant insurance for food service tenants in commercial buildings.

Need financing for a building acquisition or renovation? Commercial real estate financing and building owner loans may be an option worth exploring.

Bottom line

Commercial landlord insurance isn't built from a questionnaire. It's built from your leases. The right program is the one matched to what your lease insurance requirements, your tenant COIs, and your current rent roll actually demand — not the program your last broker copied from last year. The questions worth asking your current broker before the next renewal: when did you last read our leases, when did you last re-rate our replacement cost against current construction data, and when did you last verify our loss-of-rents limit against current rent roll?
