1. Overview: Tenant Rights in San Ramon

San Ramon is an incorporated city in the Tri-Valley area of Contra Costa County, with a population of approximately 85,000 residents. The city features a mix of single-family neighborhoods, master-planned communities, and apartment complexes, and a significant share of residents rent their homes. Renters here most commonly ask about rent increases, eviction protections, and security deposit rules.

San Ramon has no local rent-control or rent-stabilization ordinance. However, California's statewide Tenant Protection Act of 2019 (AB 1482) provides important baseline protections for most renters, including a cap on annual rent increases and a just-cause requirement before a landlord can terminate a tenancy after 12 months. Additional state laws govern security deposits, habitability, notice periods, and protections against self-help eviction. Because San Ramon is an incorporated city, any county-level tenant protections that Contra Costa County applies to its unincorporated areas do not apply within San Ramon city limits.

This guide is for general informational purposes only and is not legal advice. Laws change, and how they apply to your situation depends on the specific facts of your tenancy. For personalized guidance, contact a licensed California attorney or one of the free legal aid organizations listed below.

2. Does San Ramon Have Rent Control?

San Ramon has no local rent control ordinance. The City has not enacted any rent-stabilization or rent-control law, and because San Ramon is an incorporated city, any Contra Costa County tenant protection measures that apply to unincorporated county areas do not extend into San Ramon.

Instead, renters in covered units are subject to California's statewide rent cap under the Tenant Protection Act of 2019 (AB 1482), codified at Civil Code § 1947.12. For the August 2025 – July 2026 period, the maximum allowable increase for covered units in the Bay Area is 5% plus local CPI — up to a maximum of 10% per 12-month period. Landlords may not impose multiple increases within a year that together exceed this cap.

Important exemptions apply: single-family homes and condos are generally exempt if the landlord provides proper notice; units built within the last 15 years are exempt; and certain other categories (e.g., units subject to affordability restrictions, owner-occupied duplexes) are also exempt. If your unit is exempt, there is no statutory cap on rent increases in San Ramon beyond what your lease provides.

3. California State Tenant Protections That Apply in San Ramon

Even without a local ordinance, San Ramon renters benefit from a robust set of California state protections:

Rent cap — AB 1482 (Civ. Code § 1947.12): For covered units, annual rent increases are capped at 5% plus the regional CPI, with a hard ceiling of 10%. Landlords cannot raise rent more than twice per year, and the combined increases must stay within the cap.
Just-cause eviction — AB 1482 / SB 567 (Civ. Code § 1946.2): Once you have lived in a covered unit for 12 months, your landlord must have a legally recognized reason — such as non-payment of rent, lease violation, or a qualifying no-fault reason (owner move-in, substantial remodel, demolition) — to terminate your tenancy. SB 567, effective April 1, 2024, tightened enforcement of no-fault just-cause evictions and added relocation assistance requirements for no-fault terminations.
Security deposit cap — AB 12 (Civ. Code § 1950.5): As of July 1, 2024, most landlords may collect no more than one month's rent as a security deposit. A limited exemption applies to small landlords who own no more than two residential properties totaling no more than four units — those landlords may collect up to two months' rent (three months for furnished units) if the tenant is not active-duty military.
Security deposit return (Civ. Code § 1950.5): Landlords must return the deposit — along with an itemized written statement of any deductions — within 21 days after the tenant vacates and returns possession. Wrongful withholding can expose the landlord to a penalty of up to twice the deposit amount in addition to actual damages.
Notice to terminate (Civ. Code § 1946.1): For month-to-month tenancies, landlords must give 30 days' 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.
Habitability (Civ. Code §§ 1941.1, 1942): Landlords must maintain rental units in a fit and habitable condition — including working heat, plumbing, weatherproofing, and freedom from significant pest infestations. If a landlord fails to make necessary repairs after written notice, tenants may have the right to repair-and-deduct (up to one month's rent) or to terminate the lease.
Anti-retaliation (Civ. Code § 1942.5): A landlord may not raise rent, reduce services, or pursue eviction in retaliation for a tenant's complaint to a code-enforcement agency, request for repairs, or exercise of any legal tenant right.
Source-of-income protection (Gov. Code § 12955): Landlords may not refuse to rent or impose different terms based on a prospective tenant's lawful source of income, including housing vouchers (Section 8).
No self-help eviction (Civ. Code § 789.3): A landlord is prohibited from locking out a tenant, removing doors or windows, or shutting off utilities to force a tenant to leave. Violation entitles the tenant to actual damages plus a penalty of $100 per day for each day of the violation.

4. Security Deposit Rules in San Ramon

Security deposits for San Ramon rentals are governed by California Civil Code § 1950.5, as amended by AB 12 (effective July 1, 2024):

Deposit cap: For most landlords, the maximum security deposit is one month's rent for both furnished and unfurnished units. A limited exception applies to small landlords who own no more than two residential properties totaling no more than four units — those landlords may collect up to two months' rent (three months for furnished units) if the tenant is not active-duty military.
Return deadline: The landlord must return your deposit — along with an itemized written statement of any deductions — within 21 days after you vacate and return possession of the unit.
Permissible deductions: Landlords may only deduct for unpaid rent, costs to repair damage beyond normal wear and tear, and cleaning costs to restore the unit to the same level of cleanliness it was in at move-in.
Penalty for wrongful withholding: If a landlord acts in bad faith by wrongfully withholding all or part of your deposit, you may recover the amount wrongfully withheld plus a civil penalty of up to twice that amount, in addition to actual damages and attorney's fees (Civ. Code § 1950.5(l)).

Protect yourself by conducting a move-in walkthrough, taking dated photographs, and providing your forwarding address in writing when you move out.

5. Eviction Process and Your Rights in San Ramon

Evicting a tenant in San Ramon requires following California's formal court process — there is no legal shortcut. Here is what both landlords and tenants need to know:

Just-cause requirement (Civ. Code § 1946.2): If you have lived in a covered unit for 12 months or more, your landlord must have a legally valid reason to end your tenancy. At-fault just-cause reasons include non-payment of rent, material lease violations, subletting without permission, refusal to allow lawful entry, and criminal activity on the property. No-fault just-cause reasons include owner or family member move-in, substantial remodel, demolition, and withdrawal of the unit from the rental market. For no-fault terminations, the landlord must generally provide relocation assistance equal to one month's rent (SB 567, effective April 1, 2024).
Notice periods: For non-payment of rent, the landlord must serve a 3-day notice to pay or quit. For curable lease violations, a 3-day notice to cure or quit is required. For no-fault terminations on month-to-month tenancies, the notice period is 30 days (less than 1 year of tenancy) or 60 days (1 year or more) under Civ. Code § 1946.1.
Unlawful detainer (court) process: If the tenant does not comply with the notice, the landlord must file an unlawful detainer lawsuit in Contra Costa County Superior Court. The tenant has 5 business days to respond after being served. If the landlord prevails, the court issues a judgment and a writ of possession — only the Sheriff may physically remove the tenant.
Self-help eviction prohibited (Civ. Code § 789.3): Landlords cannot change locks, remove doors or windows, or cut off electricity, gas, water, or other utilities to force a tenant out. A landlord who does so is liable for actual damages plus $100 per day per violation, plus attorney's fees. If you are locked out or have utilities cut off illegally, contact local law enforcement and a tenant-rights organization immediately.

If you receive an eviction notice, do not ignore it — deadlines are very short. Contact Bay Area Legal Aid's Contra Costa Tenants' Rights Line at (888) 551-0068 for free legal assistance.

Frequently Asked Questions

Does San Ramon have rent control?

No. San Ramon has no local rent-control or rent-stabilization ordinance. Renters in eligible units are protected by California's statewide Tenant Protection Act (AB 1482, Civ. Code § 1947.12), which caps annual rent increases at 5% plus local CPI with a maximum of 10%, but there is no additional local ordinance on top of state law. Units exempt from AB 1482 — such as most single-family homes, condos, and buildings less than 15 years old — have no statutory cap on rent increases.

How much can my landlord raise my rent in San Ramon?

If your unit is covered by AB 1482, your landlord may raise the rent by no more than 5% plus the applicable regional Consumer Price Index (CPI), with a hard cap of 10% per 12-month period (Civ. Code § 1947.12). For the Bay Area, the 2025–2026 allowable increase is approximately 6.3% for covered units. Many units are exempt — including single-family homes and condos where proper notice was given, and units built within the last 15 years — in which case there is no statutory limit on increases. A rent hike imposed in retaliation for a protected activity is always illegal (Civ. Code § 1942.5).

How long does my landlord have to return my security deposit in San Ramon?

Your landlord has 21 days after you vacate and return possession to mail or deliver your deposit refund along with an itemized written statement of any deductions (Civ. Code § 1950.5). If the landlord acts in bad faith and wrongfully withholds your deposit, you may be entitled to the wrongfully withheld amount plus a penalty of up to twice that amount, plus actual damages and attorney's fees. Always provide your forwarding address in writing when you move out.

What notice does my landlord need before evicting me in San Ramon?

The required notice depends on the reason and length of tenancy. For non-payment of rent, the landlord must serve a 3-day notice to pay or quit. For month-to-month tenancies, at least 30 days' notice is required if you have lived there less than one year, or 60 days if you have lived there one year or more (Civ. Code § 1946.1). If you have been a tenant for 12 months or more in a covered unit, the landlord must also have a legally valid just-cause reason before terminating (Civ. Code § 1946.2). After notice, the landlord must still obtain a court judgment before you can be removed.

Can my landlord lock me out or shut off utilities in San Ramon?

No. Self-help eviction is illegal in California. Under Civil Code § 789.3, a landlord cannot lock you out, remove doors or windows, or cut off water, electricity, gas, or other services to force you out of your home. A landlord who does so is liable for your actual damages plus a civil penalty of $100 per day for each day the violation continues, plus attorney's fees. If this happens, contact local law enforcement and Bay Area Legal Aid's Contra Costa Tenants' Rights Line at (888) 551-0068 right away.

What can I do if my landlord refuses to make repairs in San Ramon?

Start by giving your landlord written notice describing the needed repair. California law (Civ. Code §§ 1941.1, 1942) requires landlords to maintain units in a habitable condition. If the landlord fails to make essential repairs within a reasonable time after written notice, you may have the right to repair-and-deduct (hiring a contractor and deducting the cost, up to one month's rent, from rent) or to terminate the lease. You can also file a complaint with the San Ramon Building Inspection division or Contra Costa County code enforcement. Retaliation by the landlord for making a repair complaint is prohibited under Civ. Code § 1942.5.
