Rental Property Rules in Petaluma, CA

If you live in Petaluma or are thinking about moving there, rental property rules are one of those things you probably won't think about until they affect you directly. Petaluma has 4 specific rules on the books covering different aspects of rental property rules, and some of them might surprise you.

Rent Control

Petaluma does not cap rent for apartments or houses, which California's Costa-Hawkins Act leaves to state law, but it does cap space rent at its mobilehome parks. Petaluma Municipal Code Section 6.50.040 limits annual mobilehome space rent increases to the lesser of seventy percent of the change in the Bay Area consumer price index or four percent, administered by a city rent stabilization program covering roughly 317 lower-income mobilehome tenants.

Key details: Governing chapter: PMC Ch. 6.50, Mobilehome Rent Stabilization. Annual increase cap: Lesser of 70% of CPI change or 4%. Notice required: 90 days written notice. Overcharge penalty: 3x amount or $500, whichever greater. Scope: Mobilehome park spaces only, not apartments.

Demanding, accepting or retaining rent above what Section 6.50.040 authorizes is unlawful under Section 6.50.130 and triggers the remedies in Section 6.50.200: the tenant can recover actual damages, attorney's fees and costs, plus a penalty of three times the unlawfully collected amount or five hundred dollars, whichever is greater. The city may also pursue injunctive relief, administrative fines, or citations under Chapters 1.10 through 1.16, and a park owner's noncompliance is an affirmative defense to an eviction action.

Compared to other cities, Petaluma takes a harder line on rent control. The enforcement and penalty structure reflects that.

Just Cause Eviction

Petaluma Municipal Code Chapter 6.60 bars landlords from ending most residential tenancies without an enumerated at-fault or no-fault just cause, going further than the statewide Tenant Protection Act it implements. Covered tenants who receive a no-fault termination, such as an owner move-in or a market withdrawal, are entitled to relocation assistance and specific additional notice before the landlord can proceed.

Key details: Governing chapter: PMC Ch. 6.60, Residential Tenancy Protections. Small-landlord exemption: 3 or fewer units, non-corporate owner. Relocation assistance: Lesser of 250% one month's rent or $9,000. Relocation payment deadline: 14 calendar days after notice. Enforcement: Affirmative defense plus civil damages/injunction.

A landlord's failure to comply with Chapter 6.60 is an affirmative defense to an unlawful detainer action under Section 6.60.100(A), and a tenant who wins a wrongful eviction case recovers costs and reasonable attorney's fees. Landlords who retaliate against a tenant for asserting rights under the chapter, or who otherwise violate it, are subject to a civil action for money damages, injunctive relief, or both, and the city itself may sue to enforce the chapter through injunctive relief or administrative fines under Chapters 1.10 through 1.16.

This is one of the stricter rules in Petaluma's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Rent Increase Notice

Mobilehome park owners in Petaluma must give affected tenants at least ninety days' written notice before any space rent increase takes effect, under Petaluma Municipal Code Section 6.50.040(F). The notice must also carry detailed financial documentation supporting the increase and information about the tenant's right to contest it through the city's rent arbitration process.

Key details: Governing section: PMC § 6.50.040(F). Notice period: 90 days written notice, minimum. Applies to: Mobilehome park space rent only. Failure to notice: Increase becomes uncollectible. Program administrator: City clerk / city manager designee.

An owner who fails to give the required ninety-day notice, or fails to include the required supporting documentation, loses the right to collect the increase from that tenant and cannot have it awarded by an arbitrator, and the failure is an affirmative defense to any possession or collection action under Section 6.50.050(D). Demanding rent above the noticed and authorized amount is separately unlawful under Section 6.50.130 and exposes the owner to treble damages or five hundred dollars, whichever is greater, under Section 6.50.200(A).

Repairs & Habitability

Petaluma requires every dwelling unit, guest room and congregate residence to have permanently installed heat capable of holding 68 degrees Fahrenheit three feet above the floor, plus working hot and cold water and sanitary fixtures, under the residential maintenance standards of Section 1.10.085.

Key details: Minimum heat: 68°F at 3 ft above floor, §1.10.085(H)(1). Hot water minimum: 120°F, per §1.10.020 definition. Bathroom fixtures required: Water closet, lavatory, tub or shower. Kitchen requirement: Working sink plus cooking appliance. Escalation path: Substandard finding can trigger §1.10.030.

A code enforcement officer can issue a notice of violation for any deficiency under Section 1.10.085, and failure to correct it within the time set, generally not less than fifteen days for non-emergency conditions, exposes the responsible party to a penalty of up to $1,000 per day under Section 1.14.050 or an administrative citation under Chapter 1.16. Severe deficiencies can support a substandard-building declaration and condemnation under Section 1.10.030.
