Apartment Building Insurance: Why the Renewal Moved, and What a Re-Quote Needs

What an Apartment Building Policy Covers, and Where Owners Get Hurt

A habitational program is a commercial package: building coverage at replacement cost (the figure a lender will accept, not the purchase price), loss of rents or business income while units are uninhabitable after a covered loss, general liability for the premises including the walkways, pools, and parking that produce most injury claims, and the endorsements the loan documents demand. Ordinance or law coverage pays the cost of bringing an older building up to current code after a loss; on a 1960s or 1970s garden-style building it is routinely the difference between rebuilding and selling the lot, and it is also one of the largest single line items on the premium, so it is a decision, not a default.

Owners get hurt in three predictable places. Undervaluation: coinsurance clauses penalize a building insured for less than the required percentage of its replacement cost, and construction costs have moved faster than most schedules. Water: the deductible structure on water damage now varies more between carriers than any other term, and the wrong one turns a routine pipe failure into an uncovered loss. And liability: habitability claims, dog bites, assault on premises, and slip-and-falls on exterior stairs are the claims that reach the limit, which is why most lenders and most prudent owners carry an umbrella above the primary.

Replacement cost, not price

Building limits are set from a reconstruction estimate the lender will accept. Coinsurance penalties apply when the limit falls below the policy's required percentage of that figure.

Loss of rents

Pays the rent you cannot collect while covered damage keeps units empty, for the period it takes to rebuild. Twelve months is common; longer rebuild timelines in permit-constrained cities argue for more.

Ordinance or law

Covers code-upgrade costs after a loss. Large share of premium on older buildings; its limit and whether to carry it are stated plainly on every proposal we issue.

Water Damage Deductibles: The Term That Decides Whether a Claim Pays

Water damage, not catastrophe, is the loss that pushed admitted carriers out of older multifamily buildings, and the market's answer has been to restructure the water deductible. Two structures are common and they are not the same thing. Some policies apply a separate per-occurrence water deductible, often $10,000 to $50,000, in place of the base deductible when the cause of loss is water. Others apply a per-unit water deductible, often $2,500 to $10,000 per affected unit, in addition to the policy deductible, so a supply-line failure that damages four units carries four deductibles plus the base.

Neither structure is wrong, but an owner who does not know which one is on the policy does not know what the policy pays. These terms are negotiable in a market where managing general agents are competing for habitational business again, and they are the concrete reason to re-quote rather than renew by inertia. We state the water deductible structure on the first page of every habitational proposal, next to the premium, because it belongs there.

Per-occurrence water deductible

One deductible per water event, replacing the base deductible. Typical range $10,000 to $50,000. Simpler to budget; higher on a single-unit loss.

Per-unit water deductible

A deductible for each unit damaged, stacked on the policy deductible. Typical range $2,500 to $10,000 per unit. Cheaper on a one-unit loss; expensive when a riser fails.

Why Renewals Moved: What Is Actually Happening in the Habitational Market

Three things are true at once, and an owner deciding whether to shop needs all three. First, the admitted carriers that retreated from older multifamily did so over water-damage frequency and liability severity, and most have not returned to pre-2020 appetites; a 1970s building with original plumbing is an E&S risk to many of them regardless of its loss history. Second, the broader commercial property market has turned: the Council of Insurance Agents & Brokers' survey for the second quarter of 2026 recorded property premiums falling 6.3 percent on average, the largest decrease of any line, and the National Multifamily Housing Council's 2024 risk survey (released March 2025) reported the first decline in multifamily property insurance rates since 2017, after 27 consecutive quarters of increases, while noting rates remain well above historical norms. Wholesale brokers describe the property marketplace heading into 2026 as highly competitive, with new carriers and managing general agents opening. Third, liability has replaced property as the harder line: wholesale market reports describe habitational casualty capacity retracting and terms tightening, large verdicts are driving umbrella pricing, and some carriers restrict assault-and-battery or habitability coverage.

The honest framing for an owner is that the market has split. A well-maintained building with updated systems and a clean loss record can often be placed with an admitted carrier at better terms than its last renewal. An older building with deferred maintenance or a water-loss history is priced by the specialty market, where the terms are negotiable but the baseline is higher. Which side of the split you are on is decided by the submission, not by the headline, and that is where we spend our time.

SB 721 Balcony Inspections, Fire Zones, and the California Rules Underwriters Ask About

California adds compliance facts to the underwriting file. Health and Safety Code section 17973 (SB 721) requires buildings with three or more units to have their exterior elevated elements (balconies, decks, walkways, stairs and their supports) inspected by a licensed professional, sampling at least 15 percent of each element type; AB 2579 moved the first-inspection deadline to January 1, 2026, which has now passed, with re-inspection every six years after. A completed SB 721 report is a submission asset: it answers the exterior-walkway question every habitational underwriter asks and documents the repairs you made.

For buildings in or near wildfire hazard zones, the sequence is the one California law sets: admitted carriers first, then the wholesale and surplus lines markets after the required diligent search, with the FAIR Plan as the documented last resort. The FAIR Plan's commercial program became more usable for larger buildings after the Insurance Commissioner's March 28, 2025 approval raised Division I limits to $20 million per building with a $100 million maximum per location; the Plan began offering the higher limits in mid-2025 under a program that runs three years, so it sunsets in 2028. It remains a named-peril fire policy that must be paired with other coverage. And since January 1, 2026, Insurance Code section 675.55 (added by SB 547) bars insurers from cancelling or non-renewing commercial property policies in ZIP codes within or adjacent to a declared fire emergency perimeter for one year after the declaration, with habitational property such as apartment complexes and multifamily buildings of more than five units expressly protected even on large policies. A protection with exceptions (for example, changes that make the risk uninsurable), but one owners in affected ZIP codes should know they have.

SB 721 (H&S 17973)

Three or more units; exterior elevated elements; at least 15 percent of each element type sampled by a licensed professional; first deadline January 1, 2026 (AB 2579); every six years after.

FAIR Plan commercial limits

$20 million per building, $100 million maximum per location (CDI approval March 28, 2025; offered from mid-2025 under a three-year program, sunsetting in 2028). Named-peril fire only; last resort after the admitted and surplus lines search.

Post-emergency moratorium

Insurance Code 675.55 (SB 547, effective January 1, 2026): one year of protection from cancellation or non-renewal for commercial property, apartment complexes and multifamily buildings expressly included, in ZIP codes within or adjacent to a declared fire perimeter.

What a Clean Submission Needs, and How We Place the Account

Underwriters price what they can verify. A habitational submission that gets competitive answers carries a statement of values with year built, construction, square footage, and unit count per building; the age of the roof, plumbing, electrical, and HVAC with dates of any replacements (copper or PEX repipes, panel upgrades, and roof replacements move pricing more than any other fact); five years of currently valued loss runs; occupancy and rent roll summary; protective devices (sprinklers, alarms, cameras, lighting); and the SB 721 report where it exists. We assemble that package from what you already have and from public records, and we ask you only for the facts we cannot look up.

Every placement starts with the admitted carriers still writing the class. When admitted coverage cannot be procured for the building, because of age, systems, loss history, or location, we work the managing general agents and surplus lines facilities that specialize in habitational property, after the diligent search California requires, and we show the comparison with the water deductible structure, the ordinance or law limit, and the liability terms stated side by side. Owners of several buildings get one program rather than a drawer of unrelated policies, with the shared terms stated once and the per-building differences listed. Titling in an LLC or trust, lender mortgagee clauses, and the 30-day notice requirements in the loan documents are handled as part of the placement, not as afterthoughts.

Systems updates are the lever

Dated evidence of repipes, electrical panel replacement, and roof replacement is the single most effective way to move an older building toward admitted terms.

One to four units is a different market

Duplexes, triplexes, and fourplexes are insured on personal-lines landlord (dwelling fire) policies with their own carriers and rate filings. Those owners belong under Rental Dwellings in our What We Insure menu; the figures on this page are for commercial habitational buildings.
