Walnut is a small, primarily residential city in the San Gabriel Valley area of Los Angeles County. Like many California cities, tenants in Walnut frequently ask whether their rent can be raised, what notice is required before eviction, and how to get their security deposit back. This guide covers those questions using the state and local laws that apply.
Walnut has not enacted a local rent control or rent stabilization ordinance. As a result, most tenant protections in the city come from California state law — principally the Tenant Protection Act of 2019 (AB 1482), as strengthened by SB 567 (effective April 1, 2024), along with the Civil Code provisions governing security deposits, habitability, and retaliation.

The City of Walnut has no local rent control or rent stabilization ordinance. The city does not operate a rent board, and there is no municipal cap on rent increases beyond what California state law provides.
Under AB 1482 (Tenant Protection Act of 2019), Civ. Code § 1947.12, landlords of covered properties may not increase rent more than 5% plus local CPI, with a maximum of 10%, in any 12-month period. For the Los Angeles area, the 2025–2026 AB 1482 allowable increase is approximately 8.0% (5% + 3.0% CPI). Only one increase is allowed per 12-month period.
Many units are exempt from AB 1482, including: single-family homes and condos where the owner provided proper written notice of the exemption; units built within the last 15 years; subsidized affordable housing with independent rent restrictions; and owner-occupied duplexes. Tenants who are unsure whether their unit is covered should review the exemption list at Civ. Code § 1947.12(d) or consult a legal aid organization.
California provides a robust set of statewide tenant protections that apply in Walnut:
Just Cause for Eviction (Civ. Code § 1946.2): Under AB 1482, as tightened by SB 567 (effective April 1, 2024), landlords of covered units may only evict a tenant who has resided in the unit for at least 12 months for an enumerated "at-fault" or "no-fault" just cause. At-fault causes include nonpayment of rent, material lease violations, and criminal activity. No-fault causes include owner move-in, substantial remodel, and withdrawal from the rental market — all of which require relocation assistance equal to one month's rent.
Habitability (Civ. Code §§ 1941.1, 1942): Landlords must maintain rental units in a habitable condition, providing working heat, plumbing, roof, and freedom from vermin. Tenants who give notice and allow reasonable time to repair may have the right to repair-and-deduct (up to one month's rent) or, in severe cases, to withhold rent.
Retaliation Prohibited (Civ. Code § 1942.5): A landlord may not raise rent, reduce services, or threaten eviction because a tenant exercised a legal right — such as requesting repairs or contacting a government agency. Retaliatory conduct can entitle the tenant to damages.
Source-of-Income Discrimination (Gov. Code § 12955): Landlords may not refuse to rent to a tenant solely because the tenant uses a housing voucher (Section 8) or other lawful source of income.
No Self-Help Eviction (Civ. Code § 789.3): A landlord may not lock out a tenant, remove their belongings, or cut off utilities to force them to leave. Violations entitle the tenant to actual damages plus a penalty of $100 per day.
Security Deposit Cap (AB 12, effective July 1, 2024; Civ. Code § 1950.5): For most new rental agreements, the maximum security deposit is one month's rent (regardless of furnished or unfurnished status). Limited exceptions apply for small landlords who own no more than two residential properties with a combined total of no more than four units.
Under California Civil Code § 1950.5, as amended by AB 12 (effective July 1, 2024), the security deposit for most residential units is capped at one month's rent. An exception allows a deposit of up to two months' rent for small landlords (owning no more than two residential properties totaling no more than four units).
Return deadline: The landlord must return the deposit — along with an itemized written statement of any deductions — within 21 calendar days after the tenant vacates (Civ. Code § 1950.5(g)). Allowable deductions include unpaid rent, cleaning costs beyond normal conditions, and repair of damage beyond ordinary wear and tear.
Penalty for wrongful withholding: If a landlord in bad faith fails to return the deposit or provides a fraudulent itemization, the tenant may sue for the amount wrongfully withheld plus a penalty of up to twice the amount of the deposit (Civ. Code § 1950.5(l)). Tenants may file a small claims court action for deposit disputes involving amounts up to $12,500.
To evict a tenant in Walnut, a landlord must follow California's statutory process. Self-help evictions — changing locks, removing doors, shutting off utilities — are illegal under Civ. Code § 789.3 and expose the landlord to substantial liability.
Notice requirements:
Just cause (covered units): Under Civ. Code § 1946.2 (AB 1482 / SB 567), tenants in covered units who have resided there for at least 12 months may only be evicted for enumerated just-cause reasons. No-fault evictions (e.g., owner move-in, substantial remodel) require the landlord to pay one month's rent as relocation assistance.
Court process: If a tenant does not comply with the notice, the landlord must file an Unlawful Detainer (UD) lawsuit in Los Angeles Superior Court. The tenant has 5 business days after service of the summons to file a written response. If the landlord prevails, the court issues a judgment and the sheriff enforces the writ of possession — the landlord cannot personally remove the tenant.
