Brentwood, CA Rental Property Rules: Rent Increase Notice (2026)

070 gives specific tenant classes rent protection tied to a condominium conversion. Under subsection (C), a tenant household in residence when the tentative map application is deemed complete, where the head of household or spouse is 62 or older or disabled under the Americans with Disabilities Act, must be offered a three-year lease once the final map is approved, and the annual rent increase on that lease cannot exceed the annual change in the Consumer Price Index, Urban Wage Earners and Clerical Workers, for the San Francisco area, calculated April to April, with the starting rent fixed at the rent charged when the tentative map application was filed.

Subsection (D) extends the same CPI cap to very-low, low, and moderate income tenant households who qualify under HUD's Section 8 income limits, except they are offered a two-year lease rather than three. Both caps sit inside the chapter's broader notice-of-intention requirement in subsection (A): the subdivider must give at least 60 days' notice before filing the tentative map, and that notice must disclose, among other required items, a statement of no rent increases and the special provisions available to senior, disabled, and lower-income tenants.

Outside the conversion window and lease term, subsection (E)(4) separately bars any rent increase between the filing of the tentative map and the tenant's relocation, lease acceptance, purchase agreement, or the map's denial or withdrawal.
