How much NFIP flood insurance can an apartment building get?
Under the National Flood Insurance Program, a residential building with five or more units can be insured for at most $500,000 of building coverage, plus up to $100,000 for the owner's contents. A lender in a high-risk flood zone generally requires the lesser of the loan balance or that maximum, so a building worth more than $500,000 is often underinsured unless you add private excess coverage.
The coverage limits, by type of building
FEMA issues apartment buildings of five or more units under the General Property Policy form; buildings of two to four units use the Dwelling Policy form (FEMA, NFIP policy forms). The maximum amounts come from federal regulation (44 CFR 61.6).
| Building type | Maximum building coverage | Maximum contents coverage |
|---|---|---|
| Single-family dwelling | $250,000 | $100,000 (residential) |
| Two to four family building | $250,000 | $100,000 (residential) |
| Other residential building, including multifamily | $500,000 | $100,000 (residential) |
| Residential condominium building | $250,000 times the number of units | $100,000 (residential) |
| Non-residential building | $500,000 | $500,000 |
Regular Program limits. The regulation notes that the building limits apply per building and that contents limits are not per building: one insured may not have more than one policy covering contents in a building, but several insureds may each have their own policy.
Per building, not per property
The $500,000 limit is for each building. A garden complex with four separate buildings on one parcel can carry up to $500,000 on each, while a single 30 unit building is capped at $500,000 in total. That difference matters when you price a purchase in a flood zone: the same unit count can be insurable for very different amounts.
Contents coverage is the owner's property, such as laundry machines you own, common-area furniture, or appliances you supply. Tenants' belongings are not covered by your policy. Tenants need their own contents coverage, which is worth saying in the lease and at move-in.
What your lender can require
Federal law tells regulated lenders not to make, increase, extend or renew a loan secured by a building in a special flood hazard area unless the building is covered by flood insurance for the term of the loan, in an amount at least equal to the outstanding principal balance or the maximum limit available for that type of property, whichever is less (42 U.S.C. 4012a). Lenders must also accept qualifying private flood insurance.
That rule sets a floor for the lender, not for you. It protects the loan balance, which can be far below what it would cost to rebuild.
Example a made-up 24 unit building in a high-risk zone would cost $3,600,000 to rebuild, and its loan balance is $2,400,000. The lender requires the lesser of $2,400,000 and the $500,000 maximum, so $500,000. If a flood did $900,000 of damage to the building, the NFIP policy would pay at most $500,000, before its deductible, and the other $400,000 or more would come from excess flood coverage, reserves, or the owner.
The 30-day wait and when it does not apply
A new NFIP policy, added coverage, or a higher limit generally takes effect at 12:01 a.m. on the 30th day after the application and premium payment (44 CFR 61.11). Two exceptions matter to apartment owners:
- Buying with a loan: when the policy is bought in connection with making, increasing, extending or renewing a loan and applied for at or before closing, coverage starts at closing.
- A new flood map: during the 13 months after a revised flood map takes effect for your community, initial coverage starts the day after application and payment.
Outside those cases, buying flood coverage because a storm is in the forecast is too late. Put the renewal date on your calendar and review limits each year, not each storm season.
A yearly flood insurance check
- Look up each building's flood zone on the current flood map and note any map changes.
- Count buildings, not units, and list each building's rebuild cost.
- Compare each building's rebuild cost with the $500,000 NFIP building limit and price excess coverage for the gap.
- List the contents you own in common areas and units and check the $100,000 contents limit.
- Confirm the named insured matches the LLC that owns the building.
- Remind tenants in writing that your policy does not cover their belongings.
- Record the premium in the insurance account for that property, and keep the declarations page with its documents.
Keeping it organized in DoorKeeping
In DoorKeeping each property keeps its own documents and books, so the flood policy, declarations page and premium sit with the building they cover, and the premium lands on the insurance line that maps to Schedule E. You can email every tenant a reminder about renters coverage. DoorKeeping costs $2 per unit per month and does not sell insurance or give advice on coverage; your agent does that.

Questions
- What is the NFIP maximum for an apartment building?
- $500,000 of building coverage per building for residential buildings with five or more units, and up to $100,000 for the owner's contents, under 44 CFR 61.6.
- Does my flood policy cover my tenants' belongings?
- No. The owner's contents coverage is for the owner's property. Tenants need their own contents policy.
- How long until a new flood policy starts?
- Generally 30 days after application and payment. Coverage bought at a loan closing starts at closing, and there is a one-day wait during the 13 months after a new flood map takes effect.
