Short-term rental rules in Walnut Creek, CA
The City of Walnut Creek effectively BANS short-term rentals: all residential rental or lease agreements within Walnut Creek city limits must be for a minimum of 30 consecutive days, and operating an STR (under 30 nights) violates city zoning ordinances. Walnut Creek's prohibition is more restrictive than Contra Costa County's STR ordinance (Ord. 2020-12, Ch. 88-32 of the County Code) which applies to UNINCORPORATED Contra Costa County and permits STRs with a county permit ($380 application fee, 90-day unhosted cap / 180-day hosted cap). The county ordinance is SUPERSEDED by Walnut Creek's stricter city ordinance within the city limits. Penalties for violation include monetary fines, cease-and-desist orders, and potential civil legal action. Walnut Creek is unusually restrictive among Contra Costa cities (Concord, Pleasant Hill, Lafayette, Orinda, Moraga, Danville, San Ramon each have different rules).

What happens if I rent without a permit in Walnut Creek?
Most cities charge per-night fines (a few hundred to a few thousand dollars per violation), escalating to cease-and-desist letters and platform delisting on repeat. Airbnb and Vrbo now share permit-validation feeds with most major cities, so unpermitted listings get blocked at the platform level. Sign in to see the specific penalty schedule for Walnut Creek.
How current is this data for Walnut Creek?
This record was verified 1mo ago against the city's published ordinance (.gov or the city's official municipal-code publisher). Cached cities re-verify on a cadence — daily for cities under active legislation, weekly otherwise. Signed-in users can hit Refresh on any city to force a fresh pull. If you're underwriting a deal, always confirm against the city's code-enforcement office before closing.
Can my HOA or condo association ban STRs even if Walnut Creek allows them?
Yes. City permits authorize you under municipal law, but your HOA, condo association, or co-op board sets contractual rules that override the city for your unit. Many HOAs adopted blanket STR bans between 2018 and 2024 in response to neighbor complaints. Read the CC&Rs, bylaws, and rental addendums before you buy with an STR plan — the city saying yes does not mean your building says yes.
