Owning the Apartment Building: It’s a Commercial Flood Policy
Flood insurance for an apartment building is written as a commercial flood policy. Through the NFIP, coverage maxes out at $500,000 for the building and $500,000 for contents per building; private commercial flood policies can insure well above that, add loss of rents or business income, and sometimes schedule multiple buildings on one policy.
Your standard commercial property or landlord package excludes flood — that’s not a gap in your particular policy, it’s how nearly every property form in the country is written. If the building carries a mortgage and sits in a high-risk flood zone, your lender requires flood coverage at the lesser of the loan balance or the maximum available, and the closing doesn’t move until it’s in place.
The structural questions we work through on every apartment file: Is the NFIP’s $500K cap anywhere near this building’s replacement cost — and if not, does private primary or an excess layer close it? What does a month of lost rents cost, and should loss-of-income coverage be in the structure (the NFIP won’t write it; private markets can)? And if it’s a multi-building property, does it qualify for a private policy that schedules every building together — one renewal, one lender file — instead of a stack of one-building NFIP policies? Those answers come from the building’s real numbers, not a rule of thumb. The full breakdown lives in our commercial flood insurance guide.
Renter’s flood policy
- Contents only — up to $100,000
- Covers furniture, electronics, clothing
- Does not cover the building or unit structure
- Severely limited below grade (basement units)
- Fast to quote, inexpensive for most renters
Building owner’s commercial flood policy
- NFIP: up to $500K building + $500K contents per building
- Private: higher limits, loss of rents addable
- Required by lenders in high-risk zones with a mortgage
- One building per NFIP policy; private can schedule multiples when the property qualifies
- Does not cover tenants’ belongings — ever
One boundary case worth naming: if the building is a condominium rather than an apartment building — individually owned units with an association — the coverage runs through a master flood policy (RCBAP) instead. That’s a different form with different rules; start with our RCBAP explainer if that’s your building.
