Landlord & commercial property insurance (loss of rents)
· Insurance type
Standard practiceWhat most planners, CPAs and attorneys recommend.
Coverage for an income building: the structure, lost rents while it is repaired, and liability to tenants and visitors.
See it on the Personal Finance & Estate map →How it works
Core pieces: property at replacement cost, business income or loss of rents (often 12 months), general liability, ordinance-or-law coverage for code upgrades when rebuilding, and equipment breakdown. Watch the coinsurance clause: insure below 80–90% of value and claims are cut proportionally. Vacancy clauses limit coverage after about 60 days empty. Require tenants to carry liability naming the owner as additional insured. Lenders set minimums and must be named; earthquake is separate. Update the statement of values yearly.
Why it matters for you
Standard practice: for a single-building owner it protects both the asset and its NOI. A loss without rent coverage can mean paying the mortgage with no income.
Rules, limits and sources (2026)
Standard ISO commercial forms (building and personal property, business income); loan covenants; California Department of Insurance reports on rising commercial premiums.
Watch out for
How far commercial premiums keep rising in California after recent wildfire and reinsurance losses is uncertain.

▸Landlord & commercial property insurance (loss of rents) is the building owner's core of Property & liability insuranceStandard practice
How they connect
For a building owner, a commercial package policy does the same two jobs: property coverage for the structure and lost rents, and general liability for injuries on site. Lenders require it, tenants' own policies sit beside it, and a commercial umbrella or excess policy adds higher liability limits on top.
When it applies
Commercial package forms were standardized by the Insurance Services Office in the mid-1980s; lenders set requirements in loan documents.
How sure?
ISO commercial property and general liability forms; loan agreements specifying required coverage; California Department of Insurance oversight.
Watch out for
How to price buildings in high wildfire or earthquake zones, and whether a state backstop grows for commercial owners, is still debated.
▸Landlord & commercial property insurance (loss of rents) is required by lenders on Commercial loans: DSCR, balloons & refinance riskLaw or rule (2026)
How they connect
Commercial loan documents require specific coverage: replacement-cost property, loss of rents typically for 12 months, liability, and often flood or earthquake in risky zones, with the lender named. Lapses trigger costly force-placed insurance or default. At refinance a new lender re-underwrites coverage, and soaring premiums cut NOI, shrinking the loan the building can support.
When it applies
Insurance requirements are standard in loan agreements and CMBS servicing guides; premiums climbed sharply after 2020, especially in California and Florida.
The rule
Loan agreements spell out coverage minimums; broker market surveys reported double-digit yearly commercial property rate increases from about 2019 through 2023.
Watch out for
Whether lenders will relax wildfire and earthquake requirements as California coverage grows scarce, or push owners toward the FAIR Plan, is unsettled.
▸Earthquake insurance (California Earthquake Authority) must be bought separately from Landlord & commercial property insurance (loss of rents)Watch out
How they connect
Commercial property policies also exclude earthquake, and the CEA doesn't cover commercial buildings. Owners buy quake coverage separately, often as a 'difference in conditions' policy, with deductibles often 5% or more of building value. Lenders commonly require it when a seismic report's probable maximum loss tops about 20%.
When it applies
Arranged through commercial brokers at purchase or refinance; lenders ordering seismic risk reports drive many of the requirements.
How sure?
Commercial policy forms exclude earth movement; lender guidelines, including CMBS standards, tie quake coverage to seismic probable-maximum-loss studies.
Watch out for
Pricing swings with global reinsurance markets; whether to insure an unencumbered building is purely a risk-tolerance choice.
