The general path — step-up in basis, probate, hold or sell — is in the inherited apartment building seller guide. Three things are specific to Santa Monica, and the first one is the whole game.
Before the valuation. Before the family conversation. Before anything.
Santa Monica records a registered maximum rent for each individual unit, and that register — not your rent roll — is the authoritative statement of what the building may lawfully earn. A buyer checks one against the other, and where they disagree the register wins.
On a building inherited after decades of family ownership, discrepancies are common and entirely fixable. Found by you, they are a correction. Found by a buyer, they are a price concession or a dead deal. See the elected board that sets your rent.
Santa Monica is a separate city. Not the LA Rent Stabilization Ordinance, not the October 1978 test, not LAHD, not Measure ULA, not the LA soft-story program. Its rent control dates from 1979 and is administered by an elected board.
An inheriting family that researches Los Angeles rent control thoroughly will reach a confident and wrong conclusion. The checklist is in the Los Angeles rules that do not reach Santa Monica.
Santa Monica's per-door values are the highest in this desk's record by a wide margin — the median is $616,667 per unit, and one closing here exceeded a million dollars a unit.
Two consequences for a family. The estate is likely worth considerably more than expected, which changes the tax conversation and makes early advice worthwhile. And the market is thin — few buildings trade in this city in any given year, the buyer pool is small and conservative, and a sale takes longer to arrange than in an actively traded submarket.
Neither of those is a reason to rush or to delay. Both are reasons to get the register in order early, because the preparation is the long pole.
Hold works where someone genuinely wants to own it — and in Santa Monica the honest case for holding is stronger than almost anywhere, because the scarcity that produces the value is not going away and the regime that constrains the income is not going to loosen.
Sell works where nobody in the family wants the job, or where several heirs need to be made whole and the asset is too valuable to divide informally.
Contact the Santa Monica Rent Control Board for the building's registered MAR by unit, and ask the city about any seismic obligation on the property. Both cost nothing. Everything else — including whether you need a valuation yet — waits on those answers.
