Suisun City is a small waterfront community of approximately 30,000 residents in Solano County, situated between Fairfield and the Suisun Marsh. Like many smaller California cities, it does not have its own rent control or tenant stabilization ordinance — renters here rely primarily on California's statewide tenant protection laws for rent increases, eviction protections, and habitability rights.
The most commonly searched tenant issues in Suisun City involve rent increases, security deposit returns, eviction notices, and repair requests. California's Tenant Protection Act of 2019 (AB 1482) sets a statewide rent cap and just-cause eviction requirement for many rental units, while Civil Code §§ 1941.1, 1942, and 1950.5 establish habitability and deposit rules that apply citywide. Tenants in single-family homes and newer buildings may have fewer protections under state law and should review their specific circumstances carefully.

Suisun City does not have a local rent control or rent stabilization ordinance. The city has not enacted any municipal law that caps how much a landlord may raise rents, beyond what California state law already requires.
For tenants in covered units, California's AB 1482 (Civil Code § 1947.12) provides a statewide rent cap: landlords may not increase rent by more than 5% plus the local Consumer Price Index (CPI), up to a maximum of 10%, in any 12-month period. However, many common unit types are exempt from this cap, including: single-family homes and condominiums where the owner has served a proper AB 1482 exemption notice; buildings constructed within the past 15 years; and owner-occupied duplexes. Tenants who are unsure whether their unit is covered should review Civil Code § 1947.12 or contact a local legal aid organization.
Because Suisun City has no local rent review board or mediation program, tenants facing large rent increases have limited local options and should seek assistance from state-level resources or legal aid.
California law provides several important tenant protections that apply throughout Suisun City:
Rent Cap (AB 1482) — Civ. Code § 1947.12: For covered rental units, landlords may not increase rent by more than 5% plus the local Consumer Price Index, up to a maximum of 10%, in any 12-month period. SB 567 (effective April 1, 2024) strengthened enforcement of this cap. Units in buildings constructed within the last 15 years, qualifying single-family homes and condos with proper exemption notices, and owner-occupied duplexes are generally exempt.
Just-Cause Eviction (AB 1482) — Civ. Code § 1946.2: Once a tenant has continuously occupied a covered unit for 12 months, the landlord must have a legally recognized just-cause reason to terminate. At-fault causes include nonpayment of rent, lease violations, nuisance, and criminal activity. No-fault causes — such as owner move-in, substantial remodel, or withdrawal from the rental market — require the landlord to pay one month's rent in relocation assistance.
Security Deposits — Civ. Code § 1950.5 and AB 12: For tenancies that began on or after July 1, 2024, the maximum security deposit is one month's rent. Deposits must be returned within 21 calendar days of move-out with an itemized statement; deductions over $125 must be supported by receipts.
Notice to Terminate — Civ. Code § 1946.1: Landlords must give 30 days' written notice to terminate a month-to-month tenancy of less than one year, and 60 days' written notice for tenancies of one year or more.
Habitability — Civ. Code §§ 1941.1, 1942: Landlords must maintain rental units in a habitable condition, including functioning plumbing, heating, electrical systems, weatherproofing, and pest-free conditions. If a landlord fails to make necessary repairs after reasonable notice, tenants may exercise the repair-and-deduct remedy — hiring a contractor and deducting the cost from rent, up to one month's rent — or in severe cases, vacate and terminate the lease (constructive eviction).
Retaliation Prohibited — Civ. Code § 1942.5: Landlords may not retaliate against tenants who exercise their legal rights, such as complaining about habitability defects, contacting code enforcement, or organizing with other tenants. A rebuttable presumption of retaliation arises if the landlord takes adverse action within 180 days of a protected activity.
Source-of-Income Discrimination Prohibited — Gov. Code § 12955: Landlords may not refuse to rent to tenants based on their source of income, including Section 8 housing vouchers.
Self-Help Eviction Prohibited — Civ. Code § 789.3: Landlords may not lock out tenants, remove doors or windows, or shut off utilities to force a tenant to leave. Such conduct exposes the landlord to actual damages plus a civil penalty of up to $100 per day for each day the violation continues.
Security deposit rules in Suisun City are governed entirely by California Civil Code § 1950.5 and, for newer tenancies, AB 12.
Maximum deposit: For tenancies that began on or after July 1, 2024, landlords may collect no more than one month's rent as a security deposit (AB 12). For tenancies that began before July 1, 2024, the prior limit of two months' rent (unfurnished) or three months' rent (furnished) may still apply.
Permissible deductions: Landlords may deduct from the deposit only for: unpaid rent; cleaning costs to restore the unit to the same level of cleanliness as at move-in (excluding normal wear and tear); and repair of damage caused by the tenant beyond ordinary wear and tear. Landlords may not charge for pre-existing damage or ordinary aging of the unit.
Return deadline: Landlords must return the deposit — or the portion not lawfully withheld — within 21 calendar days of the date the tenant vacates, accompanied by an itemized written statement. If any single deduction exceeds $125, copies of invoices or receipts must be provided.
Penalty for bad-faith withholding: If a landlord wrongfully withholds all or part of a security deposit in bad faith, the tenant may sue in small claims or civil court for the amount withheld plus a penalty of up to twice the amount wrongfully withheld, plus court costs and attorney's fees (Civ. Code § 1950.5(l)).
Evicting a tenant in Suisun City requires strict compliance with California's statutory eviction process. Self-help evictions — including lockouts, utility shutoffs, or removal of belongings — are prohibited by Civil Code § 789.3 and expose the landlord to significant monetary liability.
Required notices:
Just-cause requirement (AB 1482 — Civ. Code § 1946.2): For covered units, once a tenant has lived in the unit for 12 months, the landlord must have a legally recognized at-fault or no-fault just-cause reason to terminate. No-fault terminations require the landlord to pay one month's rent in relocation assistance. Suisun City has no local ordinance expanding these protections beyond state law.
Court process (Unlawful Detainer): If the tenant does not vacate after proper notice, the landlord must file an unlawful detainer (UD) lawsuit in Solano County Superior Court. The tenant has five business days to respond to the UD summons. If the landlord prevails, only a Solano County sheriff — acting under a court-issued writ of possession — may physically remove the tenant from the unit.
