In Los Angeles the Rent Stabilization Ordinance reaches residential units attached to a commercial building, the soft-story retrofit program reached commercial buildings as well as apartments, and the state fire code sets the rules for a restaurant tenant’s hood and duct. Tell me what is on the ground floor, how many units are above it and what paper you hold on each, and I can place the building as what it is.
Why an apartments-over-retail building is read differently here
- RSO upstairsThe Housing Department (LAHD) lists “residential unit(s) attached to a commercial building” among the property types the Rent Stabilization Ordinance covers, generally where the property was first built on or before October 1, 1978.
- The ground-floor tenantA nail salon, a dry cleaner and a restaurant with a charbroiler are three different fire risks under the same bedrooms. The occupancy sets the rate and the market.
- Open ground floorsStorefront glass and tuck-under parking are the conditions the city’s soft-story program was written for.
- Two rent streamsResidential rent that is regulated and commercial rent that depends on a lease, both stopped by the same fire.
- ConversionsThe citywide Adaptive Reuse Ordinance is turning more commercial buildings into housing, often with shops kept at street level.
The coverage parts are the usual ones (how a mixed-use policy is built). What follows is what Los Angeles adds, as of November 2026.
The RSO follows the units above the shop
Owners sometimes assume a building zoned and taxed as commercial sits outside rent stabilization. LAHD says otherwise: the ordinance generally applies to rental properties first built on or before October 1, 1978, and its list of covered types includes residential units attached to a commercial building, along with replacement units built under the ordinance’s replacement-unit section. Covered units must be registered with LAHD every year.
That matters to the insurance in three places:
- The rent roll is the exposure. Loss of rents is written on what you actually collect, and regulated rents upstairs are often well under the street.
- Planned work has a process. Re-piping, re-wiring, a new service panel or a seismic retrofit in an RSO building falls within LAHD’s Tenant Habitability Program, which requires a plan for protecting tenants while the work goes on.
- Tenant claims come from housing rules. Habitability and wrongful-eviction allegations are residential claims, and some policies written for commercial landlords limit or exclude them. Read the form.
A restaurant under the apartments
A cooking tenant changes the building more than any other occupancy. Grease in a hood and duct that runs up through or beside the residential floors is how a kitchen fire becomes a building fire, and underwriters ask about it before anything else.
The 2025 California Fire Code sets the baseline:
- Type I hoodRequired at or above commercial cooking appliances that produce grease vapors (Section 606.2).
- Inspection scheduleHoods, grease-removal devices, fans and ducts are inspected every three months for high-volume cooking such as 24-hour operation, charbroiling or wok cooking, every month for solid-fuel cooking, every twelve months for low-volume operations, and every six months for everything else.
- CleaningIf the inspection finds grease accumulation, the components must be cleaned to the referenced industry standard.
- Records and tagsEach inspection and cleaning is recorded with the company and date, and a service tag is posted on the system.
The fire code official can approve different intervals, so the tenant’s LAFD paperwork governs. For the building owner, the lease is the control: it should require the tenant to keep the hood, duct and extinguishing system serviced on that schedule, give you the reports, carry liability limits that fit a building with people sleeping above, and name you as additional insured. I ask for the last two hood-cleaning reports and the suppression system tag with every submission that has a kitchen in it. The tenant’s own coverage is a separate placement; see restaurant insurance.
Soft-story status and earthquake
The soft-story program (Ordinances 183893 and 184081) covers wood-frame buildings of two or more stories, built under code standards enacted before January 1, 1978, with ground-floor parking or similar open floor space. It does not apply to residential buildings with three or fewer units. LADBS sent orders by priority group between May 2016 and November 2017, the last group being condominiums and commercial buildings, and owners had seven years from the order to finish construction. A two-story building with shops below and four flats above, built in the 1960s, is the kind of structure the program describes.
If your building received an order, the certificate of compliance is the document that matters. If it did not, say so and say why; underwriters ask either way.
Earthquake is typically excluded from the property policy and is bought separately in the commercial market. The California Earthquake Authority writes homeowners, condo unit owners, mobilehome owners and renters, not a mixed-use building, though your residential tenants can buy its renters policy for their own belongings. How earthquake coverage works in California.
Loss of rents on both floors, and tenant relocation
One fire stops two kinds of income, and they come back on different clocks.
- Commercial rent depends on the lease. Many leases let a tenant terminate if the space cannot be restored within a stated time, and a restaurant build-out can outlast the repair of the shell. Size the limit and the period of restoration for the slower of the two.
- Residential rent comes back at the regulated figure. After certain landlord terminations of tenancy, the RSO allows a unit to be re-rented only at the lawful rent in effect when the tenancy ended, plus the permitted annual adjustments. Do not model the recovery on market rent.
- Relocation after a casualty turns on a city finding. Under the municipal code a landlord is not liable for relocation benefits when the enforcement agency determines the unit became unsafe because of a fire, flood, earthquake or other event beyond the landlord’s control that the landlord did not cause or contribute to. The RSO’s relocation section carries the same exception. The city decides, and deferred maintenance can undo it.
- Relocation during planned work is different. If renovation covered by the Tenant Habitability Program will affect a unit’s tenantability for 30 days or more, the tenant may choose to end the tenancy and take permanent relocation assistance.
Whether a policy pays any relocation cost depends on its rental value and extra expense wording. I read that wording against the building before recommending a form. How income coverage works.
Adaptive reuse and newly mixed buildings
The City Council adopted a Citywide Adaptive Reuse Ordinance (No. 188,793) that sets zoning incentives and streamlined procedures for converting existing commercial buildings into five or more residential units. The original 1999 ordinance applied only to buildings built before 1974 in or near Downtown. City Planning says the updated ordinance extends eligibility to all neighborhoods and to buildings at least 15 years old in multifamily residential, commercial, parking and public facilities zones, with many projects able to go straight to LADBS for a building permit.
For insurance, a conversion is three risks in sequence:
- During construction: builder’s risk on the work, with the existing structure insured as well, since a standard property policy restricts coverage for a building under major renovation.
- At lease-up: a partly occupied building, which some property forms treat as vacant below a stated occupancy.
- Once stabilized: a mixed-use policy written on the new occupancy, the new systems and the rebuilt replacement cost, not the old office schedule.
An older shell rebuilt after a loss must also meet current code. Ordinance or law coverage pays that difference up to its own limits, and on a pre-1978 mixed-use building I treat it as a main limit, not an afterthought.
What to send me
- Address, year built, construction type and stories, with square footage split between residential and commercial.
- Each commercial tenant and what it does, with the lease insurance clause and the tenant’s certificate.
- For any cooking tenant: hood and duct cleaning reports, the suppression system service tag and the type of cooking.
- The residential rent roll, marked for RSO units, and the commercial rent roll with lease expiration dates.
- Soft-story status: order to comply, permits and certificate of compliance, or a note that no order was issued.
- Current declarations pages and five years of loss runs.
- Updates with years: roof, plumbing, electrical, heating, sprinklers and alarms.
Common questions
Who insures apartments over retail in Los Angeles?
Standard and surplus lines markets both write mixed-use buildings, and which one fits depends on the ground-floor tenant, the age of the building, its retrofit status and losses. A restaurant downstairs narrows the list more than any other single fact.
Does the Los Angeles RSO apply to apartments above a store?
Generally yes if the property was first built on or before October 1, 1978. LAHD lists residential units attached to a commercial building among the property types the ordinance covers.
Why is my mixed-use building insurance higher with a restaurant tenant?
Commercial cooking is the main fire source in a building with people living above it. Underwriters rate on the type of cooking and on proof the hood, duct and suppression system are inspected and cleaned on the fire code schedule.
Do I need earthquake insurance on a mixed-use building in Los Angeles?
It is not required by law, but earthquake is typically excluded from the property policy and lenders often ask for it. It is bought as a separate commercial policy, and retrofit status drives the terms.
Do I have to pay to relocate tenants after a fire in my mixed-use building?
Not necessarily. City code says a landlord is not liable for relocation benefits when the city determines the unit became unsafe from a fire or other event beyond the landlord’s control that the landlord did not cause or contribute to; the city makes that call case by case.
Does loss of rents cover both the apartments and the store?
It should, but only if the limit was built from both rent rolls. Check that the residential and commercial rents are both scheduled and that the restoration period fits the slower of the two to recover.
Does the soft-story retrofit apply to a building with shops on the ground floor?
It can. The program is defined by wood-frame construction, pre-1978 code standards and an open ground floor, and LADBS sent orders to commercial buildings as well as apartments; residential buildings with three or fewer units are excluded.
General information about insuring mixed-use buildings in the City of Los Angeles as of November 2026, not legal advice. RSO coverage, relocation rules, retrofit orders, fire code requirements and adaptive reuse rules are set by city ordinance and state code and they change; confirm your building’s status with LAHD, LADBS, LAFD and City Planning, and your obligations with counsel. Coverage depends on underwriting and the terms, conditions and exclusions of the policy actually issued.
