Insurance Requirements: Martinez vs Walnut Creek
How do insurance requirements rules compare between Martinez, CA and Walnut Creek, CA?
Martinez has fewer restrictions than Walnut Creek.
Martinez, CA
Contra Costa County
Martinez has not adopted a short-term rental ordinance, and the city does not impose a minimum liability-insurance requirement on short-term lodging operators. California has no statewide STR insurance mandate either - insurance minimums are set by each city or county that has adopted an STR program, and Martinez has not done so. Hosts are nonetheless strongly advised to carry commercial-grade liability and property coverage, because standard homeowner's policies typically exclude paid short-term lodging activity.

Martinez FAQ
Does Martinez require a short-term rental host to carry liability insurance?
No. Martinez has not adopted a short-term rental ordinance and does not impose a minimum liability-insurance amount, certificate-of-insurance filing, or additional-insured requirement on STR operators. Any insurance condition would only arise case-by-case through a bed-and-breakfast or conditional use approval under Section 22.04.051.
Does California state law require STR insurance?
No. California does not have a statewide minimum liability-insurance requirement for short-term rentals. AB 2873 (2022) is unrelated - it addresses affordable-housing tax credit allocation and supplier diversity, not STR insurance. Any STR insurance minimum comes from the local city or county, and Martinez has not adopted one.
Will my homeowner's policy cover Airbnb or Vrbo guests?
Usually not. A standard homeowner's policy typically treats paid short-term lodging as a business use and may deny claims tied to a paying guest. Most hosts purchase a dedicated short-term rental policy or commercial landlord policy, often with $1 million per-occurrence liability. Platform programs like Airbnb's AirCover supplement rather than replace a host's own primary coverage.
Walnut Creek FAQ
Does Walnut Creek require liability insurance for short-term rentals?
No, because Walnut Creek does not list short-term rental as a permitted use and does not issue STR permits. The city has no STR-specific insurance minimum.
Will my homeowner's insurance cover an Airbnb in Walnut Creek?
Most California homeowner policies exclude commercial rental activity, so claims arising from a paid stay under 31 days may be denied. Operating one in Walnut Creek also remains a zoning violation regardless of insurance status.
Can I run an STR out of my ADU if I have insurance?
Short-term rental in an accessory dwelling unit requires a Conditional Use Permit from Walnut Creek Planning, and insurance alone does not authorize the use. Contact DutyPlanner@walnut-creek.org before listing.
