Owner Compliance Guide tailored for Marin and Sonoma landlords


Owning rental property in the North Bay requires careful compliance with a growing number of rules at the state and local level. While most landlords act in good faith, many disputes arise simply from procedural mistakes.

This short guide highlights 10 essential compliance principles that every property owner in Marin and Sonoma counties should keep in mind.

#1. Security deposits are strictly limited

Under California law, most landlords may collect no more than one month’s rent as a security deposit.
A limited exception allows two months’ rent if:


  • the landlord qualifies as a small landlord, and
  • the property owner owns no more than two rental properties with a total of four units or fewer.

Large landlords must follow the one-month limit. Deposit handling rules are strictly enforced

#2. Security deposits must be returned properly

After a tenant vacates:

  • the deposit must be returned within 21 days
  • itemized deductions must be provided in writing
  • invoices or receipts may be required for larger deductions

Failure to comply can expose landlords to penalties of up to twice the deposit amount. Documentation is critical.

#3. Rent increases are often limited

Many California rental properties are subject to the statewide AB 1482 rent cap.
For covered units:
Maximum increase per year:
5% + local CPI (typically around 8–10%)

Properties exempt from AB 1482 still require proper disclosure of exemption status in the lease.
Several Marin cities also have additional rent regulations.

#4. Terminating a tenancy requires “just cause”

For many properties, landlords cannot simply end a tenancy at will.
Under Just Cause eviction rules, termination must generally fall into two categories:

  • Tenant fault
    (non-payment of rent, lease violations, nuisance)
    or
  • No-fault reasons such as:
    • owner move-in
    • major renovation
    • property withdrawal from the rental market

Certain no-fault terminations require relocation payments to tenants (up to 3 months of rent)

#5. Fair Housing rules apply to all owners


Federal and California fair housing laws prohibit discrimination based on protected characteristics including:

• race
• religion
• national origin
• disability
• family status
• sexual orientation
• source of income

Screening criteria must be consistent, documented, and applied equally to all applicants.
Even informal comments can create liability.

#6. Habitability standards are strict

California requires rental properties to remain safe and habitable at all times.
Landlords must maintain:

• plumbing, heating, and electrical systems
• weatherproofing and structural integrity
• functioning smoke and carbon monoxide detectors

Tenants may have legal remedies if conditions fall below habitability standards.
Preventative maintenance is key.

#7. Entry into the property requires notice


Except for emergencies, landlords must generally provide at least 24 hours’ written notice before entering a rental unit.

Valid reasons include:
• repairs
• inspections
• showing the property to prospective tenants or buyers

Improper entry can expose landlords to claims of tenant harassment or privacy violations.

#8. Documentation matters more than most owners realize

In many housing disputes, the outcome depends not on what happened — but on what can be documented.

Owners should maintain records of:
• leases and addenda
• maintenance requests and repairs
• tenant communications
• notices served
• deposit accounting

Clear documentation protects both parties.

#9. Local regulations can apply – especially in Marin & Sonoma

Some Marin and Sonoma jurisdictions have additional local housing rules, including:
• rent stabilization ordinances
• tenant protections
• registration requirements

Cities with notable housing regulations include:
• San Rafael
• Larkspur
• Fairfax
• San Anselmo
• Petaluma
• Santa Rosa

Local rules can change frequently.

#10. The regulatory landscape is constantly evolving

California housing regulations continue to evolve as policymakers respond to housing shortages and tenant protections.

Owners should stay informed about:

• new statewide legislation
• local housing ordinances
• evolving compliance standards

Small procedural errors can sometimes have disproportionate consequences.

Careful management helps reduce risk.
