Almost certainly — and under a system that is structurally different from the one most owners will have read about.
Santa Monica is a separate city. The LA City Rent Stabilization Ordinance does not apply here, and neither does its October 1978 certificate-of-occupancy test or LAHD registration.
Santa Monica has had its own rent control since 1979, administered by an elected Rent Control Board rather than a city department, with a registered Maximum Allowable Rent recorded for each individual unit.
Not the certificate of occupancy. Not your rent roll. The MAR register.
Santa Monica records what each unit may lawfully charge. That figure is authoritative, and a buyer's diligence checks your rent roll against it rather than the other way round. Where they disagree, the register is right and the rent roll is the problem — which is why pulling and reconciling it, unit by unit, is the first thing a Santa Monica owner should do and the last thing most of them do.
The mechanics are in Santa Monica rent control, explained and the structure in the elected board that sets your rent.
At the 2020 census 72.9% of occupied housing units were renter-occupied, in a city of 8.42 square miles built out long before the ordinance existed. Exemptions exist under state law for certain construction, but the older, smaller stock that makes up most of what trades here is squarely inside the system.
Buyers underwrite what the register permits, not what an open market would bear. That is the dominant valuation input, and it is why Santa Monica values are what they are net of a very tight regime rather than in spite of one.
And the register is where escrows come apart. A unit collecting above its registered maximum is not a pricing advantage — it is an exposure, and one a buyer will price hard or walk from.
Everything you have read about the LA City RSO. It is accurate, well-written, and about a different jurisdiction with a different instrument. The full list of what does not reach here is in the Los Angeles rules that do not reach Santa Monica.
