Walnut Creek is a mid-sized city of roughly 70,000 residents in Contra Costa County, about 25 miles east of San Francisco. Renters in Walnut Creek commonly ask whether the city has rent control, how much notice a landlord must give before a rent increase, and what protections exist against no-fault evictions.
Walnut Creek does not have its own local rent control or just-cause eviction ordinance. Instead, tenants rely entirely on California statewide protections, most importantly the Tenant Protection Act of 2019 (AB 1482, Civ. Code §§ 1946.2 and 1947.12) and the security-deposit reform enacted by AB 12 (effective July 1, 2024). These laws provide meaningful safeguards for many—but not all—rental units.

Walnut Creek has no local rent control ordinance. The city has not enacted any municipal cap on rent increases beyond what California state law requires.
California's Tenant Protection Act (AB 1482, codified at Civ. Code § 1947.12) provides a statewide rent cap: landlords may not raise rent by more than 5% plus the local Consumer Price Index (CPI), with an absolute ceiling of 10% per year, in any 12-month period. This cap applies only to covered units—generally multifamily buildings that are at least 15 years old and are not otherwise exempt. Exemptions include single-family homes and condos where the owner has provided proper written notice of the exemption, and properties owned by certain small landlords.
Because Walnut Creek has no local ordinance, tenants in exempt units have no rent-increase protection beyond the general obligation of good faith dealing. If you are unsure whether your unit is covered, contact Bay Area Legal Aid or review the plain-language FAQ published by the California Department of Justice.
Just-Cause Eviction (Civ. Code § 1946.2): Under AB 1482, as tightened by SB 567 (effective April 1, 2024), landlords of covered units must have a legally recognized reason—either an at-fault cause (e.g., nonpayment of rent, lease violation, nuisance) or a no-fault cause (e.g., owner move-in, substantial remodel, withdrawal from rental market)—to terminate a tenancy after the tenant has lived in the unit for at least 12 months. For no-fault evictions, the landlord must provide one month's rent in relocation assistance or waive the last month's rent.
Security Deposits (Civ. Code § 1950.5; AB 12, eff. July 1, 2024): Landlords may collect no more than one month's rent as a security deposit for most residential units. A limited exception allows up to two months for small landlords (natural persons owning no more than two properties with four or fewer total units). Deposits must be returned within 21 days of the tenant vacating, accompanied by an itemized written statement and receipts for any deductions.
Habitability (Civ. Code §§ 1941.1, 1942): Landlords must maintain rental units in a habitable condition, including providing working plumbing, heat, weatherproofing, and freedom from vermin. If a landlord fails to make repairs after reasonable notice, tenants may—under limited conditions—repair and deduct costs from rent (up to one month's rent) or vacate and claim constructive eviction.
Retaliation Prohibition (Civ. Code § 1942.5): A landlord may not retaliate against a tenant for exercising legal rights, such as complaining to a housing inspector or organizing with other tenants. Retaliatory conduct within 180 days of such activity is presumed unlawful.
Source-of-Income Protection (Gov. Code § 12955): Landlords may not discriminate against tenants or applicants because they use housing vouchers or other lawful sources of income.
Self-Help Eviction Prohibited (Civ. Code § 789.3): Landlords may not lock out, remove doors or windows, or shut off utilities to force a tenant to leave. Tenants subjected to self-help eviction may recover actual damages, punitive damages of up to $100 per day, and attorney's fees.
Notice of Termination (Civ. Code § 1946.1): For month-to-month tenancies, landlords must give at least 30 days' written notice if the tenant has lived there less than one year, or 60 days' notice if the tenant has lived there one year or more.
Under California Civil Code § 1950.5, as amended by AB 12 (effective July 1, 2024), the maximum security deposit a landlord may collect for a residential unit in Walnut Creek is one month's rent—regardless of whether the unit is furnished or unfurnished. This is a reduction from prior law, which allowed up to two months for unfurnished and three months for furnished units.
Small-landlord exception: A landlord who is a natural person (or an LLC whose members are all natural persons) and who owns no more than two residential rental properties comprising no more than four total units may collect up to two months' rent as a deposit, unless the prospective tenant is a service member.
Return deadline: Within 21 calendar days after a tenant vacates, the landlord must either return the full deposit or mail an itemized written statement explaining each deduction, along with copies of receipts or invoices for repair work costing $125 or more. Failure to comply forfeits the landlord's right to keep any portion of the deposit and may expose the landlord to a penalty of up to twice the deposit amount (in addition to actual damages) if a court finds the withholding was in bad faith (Civ. Code § 1950.5(l)).
Notice Requirements: Before filing an eviction lawsuit, a landlord must first serve the tenant with a written notice. Common notice types include: a 3-Day Notice to Pay Rent or Quit (for nonpayment of rent); a 3-Day Notice to Cure or Quit (for curable lease violations); a 3-Day Notice to Quit (for incurable violations such as serious nuisance or criminal activity); and a 30- or 60-Day Notice to Terminate Tenancy for no-fault terminations (Civ. Code § 1946.1—30 days if tenancy is less than 1 year, 60 days if 1 year or more).
Just-Cause Requirement (Civ. Code § 1946.2): For tenants in covered units who have lived there at least 12 months, the landlord must state a legally valid just-cause reason in the termination notice. At-fault just causes include nonpayment of rent, material lease violations, damage to the property, and nuisance. No-fault just causes include owner or close family member move-in, substantial remodel requiring vacancy, compliance with a government order, and withdrawal of the unit from the rental market. No-fault evictions require relocation assistance equal to one month's rent, or a waiver of the last month's rent.
Unlawful Detainer Process: If the tenant does not comply with the notice, the landlord may file an Unlawful Detainer (UD) lawsuit in Contra Costa Superior Court. The tenant has 5 court days to file a written response after being served with the UD summons and complaint. If the court rules for the landlord, a Writ of Possession is issued and the sheriff will schedule a lockout. The entire court process typically takes several weeks to months.
Self-Help Eviction Prohibited (Civ. Code § 789.3): Regardless of the reason for eviction, a landlord in Walnut Creek may never use self-help measures such as changing locks, removing doors or windows, or cutting off utilities to force a tenant out. Tenants harmed by self-help eviction may recover actual damages, punitive damages of $100 per day of violation, and attorney's fees.
