Summary
Walnut Creek does not operate a citywide rental registry for long-term rentals. Landlords must obtain a business license for rental activity. California AB 1482 (Tenant Protection Act) applies statewide to most rentals, requiring just cause and capping annual rent increases.
1947.12. (a) (1) Subject to subdivision (b), an owner of residential real property shall not, over the course of any 12-month period, increase the gross rental rate for a dwelling or a unit more than 5 percent plus the percentage change in the cost of living, or 10 percent, whichever is lower, of the lowest gross rental rate charged for that dwelling or unit at any time during the 12 months prior to the effective date of the increase. In determining the lowest gross rental amount pursuant to this section, any rent discounts, incentives, concessions, or credits offered by the owner of such unit of residential real property and accepted by the tenant shall be excluded.
Full Breakdown
Walnut Creek does not require a rental property registration program for long-term residential rentals beyond the standard business license requirement. Landlords renting residential property in Walnut Creek must obtain and maintain a City business license and pay the applicable business license tax. Short-term rentals (under 30 days) may have separate requirements. At the state level, California AB 1482 (the Tenant Protection Act of 2019) applies to most rental properties in Walnut Creek and provides just-cause eviction protections after 12 months of tenancy and caps annual rent increases at 5% plus CPI (maximum 10% total) for covered units.
AB 1482 exempts single-family homes not owned by corporations/REITs (with proper disclosure) and units built within the last 15 years. Landlords must provide written AB 1482 disclosure to tenants. 12 codify the just cause and rent cap provisions. Walnut Creek does not have local rent control beyond the state AB 1482 framework. Security deposits are capped at state-level limits (updated by AB 12 in 2024 to 1 month for most rentals).
