San Diego Landlord Laws: What Every New Rental Owner Must Know

Starting out as a landlord in San Diego means learning two layers of rules:

1. California state landlord–tenant law (very detailed and tenant‑friendly), and
2. Local San Diego / San Diego County rules and ordinances.

Below is a clear, practical overview to help new rental owners avoid costly mistakes and stay compliant. This is general information, not legal advice—when in doubt, talk with a local landlord–tenant attorney or professional property manager.

1. Who’s Covered: What Types of Rentals Do These Laws Apply To?

Most of these rules apply to:

• Single‑family homes, condos, and townhomes
• Small multifamily (duplexes, triplexes, fourplexes)
• Larger apartment buildings

Special cases with additional or different rules:

• Short‑term rentals (Airbnb, VRBO, etc.) – different city rules and permits
• Mobile home parks – governed by separate laws
• Section 8 / subsidized housing – additional federal and program rules

If you’re renting a typical home, condo, or apartment to a long‑term tenant (month‑to‑month or 1‑year lease), assume California landlord‑tenant law applies.

2. Written Leases, Disclosures & Move‑In Requirements

Written rental agreement

In California, a written agreement is strongly recommended for all rentals and is essentially expected by the courts. It should clearly cover:

• Rent amount, due date, and how rent is paid
• Lease term (fixed-term or month-to-month)
• Late fees (if allowed and reasonable), returned check fees
• Security deposit amount and conditions for deductions
• Utilities: who pays for what
• Occupancy limits and guest policies
• Maintenance responsibilities (yard, pool, etc.)
• Pet policy and pet deposits (where applicable)

Required disclosures (common ones for San Diego rentals)

Landlords must provide various disclosures, often in writing and sometimes as separate forms:

• Lead-based paint disclosure (federal) – for homes built before 1978
• Bedbug disclosure – California requires specific language if you know of infestations
• Pest control notice – when regular pest control services are used
• Asbestos disclosure – if you know asbestos is present
• Megan’s Law disclosure – standard California language on sex offender database
• Flood hazard disclosure – if the property is in a flood hazard area
• Smoking policy – clarify whether smoking is allowed and where
• Prop 65 warnings – for certain buildings or exposures
• Utilities / ratio billing – if you use RUBS or shared meters, you must explain

Local or HOA rules (parking, trash, noise, pool rules, etc.) should also be given in writing.

A property manager will often have a compliant “package” of disclosures ready; if you self-manage, use California-specific lease forms (e.g., from CAR, CAA) and keep them current.

3. Security Deposits: How Much, How to Handle, and How to Return

California is strict about security deposits, and a new law significantly lowered the cap for most landlords as of July 1, 2024.

Maximum security deposit (current law)

For most San Diego rental owners:

• Maximum deposit:
• Up to 1 month’s rent total, whether furnished or unfurnished
• This includes any “pet deposit” – the combined total cannot exceed one month’s rent

There are very limited exceptions for certain “small landlords.” Some mom-and-pop owners (for example, those who don’t own more than a small number of units and meet specific criteria in the statute) may be allowed to collect up to two months’ rent. Because the rules are technical and can change, it’s safest to:

• Assume 1 month’s rent is the cap unless you’ve confirmed, with an attorney or professional manager, that you qualify for a higher limit.

Holding the deposit

• You don’t have to use a separate bank account, but many landlords do as a best practice.
• Treat the money as the tenant’s funds, held in trust, only to be used for allowable deductions at move-out.

Returning the deposit

Deadlines and paperwork are critical:

• Within 21 calendar days after the tenant moves out, you must either:
• Return the full deposit, or
• Return the remaining balance plus an itemized statement of deductions.

For any deduction over $125, you must:

• Provide copies of receipts or invoices for the work, or
• A good faith estimate if the work isn’t done yet (followed by receipts when available).

You may deduct for:

• Unpaid rent or authorized late fees
• Cleaning needed to restore the unit to move-in level cleanliness (not better)
• Damage beyond normal wear and tear
• Missing or damaged items (e.g., blinds, screens) that were provided at move-in

You may not deduct for:

• Normal wear and tear (traffic wear on carpet, minor scuff marks, faded paint)
• Damage that already existed at move-in and was never repaired

Pre–move-out inspection

If the tenant requests it, you must offer a pre–move-out inspection:

• Usually about 2 weeks before the tenant’s move-out date
• You walk through, note potential deductions, and provide a written list of items the tenant can fix or clean before leaving
• This reduces disputes and helps you both align expectations

Use a written move-in checklist and lots of photos at both move-in and move-out to support any deductions you make.

4. Rent, Late Fees, and Rent Increases (AB 1482 & Local Practice)

Charging and collecting rent

• Set rent in the lease and state due dates and grace periods clearly.
• Online payments are common; always give the tenant a way to pay rent that doesn’t require special tech (e.g., check or money order) to stay on safe legal ground.

Late fees

• Must be reasonable and specified in the lease (e.g., a flat amount or small percentage).
• Excessive late fees can be challenged in court.
• You cannot charge “hidden” or retroactive late fees not disclosed in the lease.

California rent control (AB 1482) – does it apply to you?

AB 1482 (Tenant Protection Act) imposes:

• Rent increase caps (roughly 5% + CPI, up to a statewide max per year), and
• “Just cause” eviction rules after 12 months of tenancy,

for most multifamily properties older than 15 years.

However, some properties are exempt, including:

• Most single‑family homes and condos if:
• Owned by an individual, LLC with all individual members, or family trust, and
• Proper exemption notice is given in the lease
• Some new construction (less than 15 years old)
• Certain affordable housing / deed‑restricted properties

Whether AB 1482 applies is critical for:

• How much you can raise rent each year
• Whether you can end a tenancy without cause

Get clarity on your property type and give tenants the correct AB 1482 or exemption notice in the lease.

5. Habitability & Repairs: Your Core Obligations as a Landlord

California requires landlords to provide and maintain “habitability” under Civil Code §1941.1 and the implied warranty of habitability.

You must:

• Provide a safe, weatherproof unit with working:
• Plumbing (hot and cold water)
• Heating
• Electrical
• Locks on doors and windows
• Ensure the property is free from significant health and safety hazards, including:
• Serious leaks and mold issues
• Rodent or insect infestations
• Dangerous stairs, railings, or structural problems
• Comply with building, housing, and health codes enforced by San Diego City or County.

Repair timelines

While the law uses “reasonable time,” practical expectations are:

• Emergencies (no heat in winter, major leaks, sewage backups, unsafe wiring): same day or 24 hours when possible
• Urgent issues (broken exterior locks, appliance failure where no substitute exists, major plumbing issues): 24–72 hours
• Non‑urgent repairs (minor leaks, cosmetic issues): within 1–2 weeks

Tenants generally must:

• Notify you of needed repairs in writing
• Allow reasonable access to the unit for repairs (with proper notice)

Repeated failure to address legitimate habitability issues can:

• Allow tenants to withhold rent or make “repair and deduct” claims (under specific rules)
• Trigger city or county code enforcement
• Lead to damages and attorney’s fees in court

6. Entry, Privacy & Notice Requirements

California strongly protects tenant privacy.

As a landlord, you may enter a unit only for specific reasons:

• Repairs and maintenance
• Inspections (within reason)
• Showing the unit to prospective tenants, buyers, or lenders
• In case of emergency (fire, serious water leak, etc.)
• When the tenant has abandoned or surrendered the property
• Pursuant to a court order

Notice requirements

• Non‑emergency entry: generally 24 hours’ written notice
• You must state:
• Date and approximate time range of entry
• Reason for entry
• Entry must be during normal business hours unless the tenant agrees otherwise.

Repeated harassment or “drop‑ins” without notice can be considered illegal entries and lead to penalties.

7. Fair Housing Laws: Avoiding Discrimination Claims

California and federal law strictly prohibit discrimination when:

• Advertising rentals
• Screening applicants
• Setting terms and conditions
• Handling maintenance and complaints
• Renewing or terminating tenancies

You may not discriminate based on (including but not limited to):

• Race, color, national origin, or ancestry
• Religion
• Sex, gender identity, sexual orientation
• Familial status (kids, pregnancy)
• Disability (physical or mental)
• Marital status
• Source of income (including housing vouchers)
• Age (with some senior housing exceptions)
• Other protected categories under California law

Practical tips

• Use the same written criteria for every applicant (income, credit, rental history, etc.)
• Apply criteria consistently—no making exceptions based on gut feeling.
• Be especially careful with disability-related requests for reasonable accommodations (e.g., service dogs, reserved parking space, allowing a live-in aide).
• Assistance animals are not pets; you generally cannot charge pet rent or pet deposit for them.

Discrimination complaints can lead to investigations, fines, and costly lawsuits. If you’re unsure about a situation, get advice before acting.

8. Ending a Tenancy & Evictions (San Diego County)

Ending a tenancy and evicting are very different:

• Ending a tenancy = proper notice to vacate, tenant leaves voluntarily
• Eviction = court process (unlawful detainer) when a tenant doesn’t leave or violates terms

Notice to terminate (no-fault) – depends on property and law

Before AB 1482 and some local rules, landlords could often:

• End a month‑to‑month tenancy with a 30‑day notice (or 60 days if tenant had been there more than 1 year).

Now, for many properties covered by AB 1482, you need “just cause” to terminate a tenancy after 12 months, even on month-to-month:

• At-fault just cause (e.g., nonpayment of rent, lease violations, illegal activity), or
• No-fault just cause (e.g., owner move-in, substantial remodel, withdrawal from rental market) with relocation assistance.

Common reasons to file an eviction (unlawful detainer)

• Nonpayment of rent (after proper 3‑Day Notice to Pay or Quit)
• Serious or repeated lease violations (after an appropriate notice to cure or quit)
• Nuisance or illegal activity
• Holding over after lease expiration when lawful notice was given and just cause, if required, is met

Process overview (very simplified)

1. Serve the correct legal notice (3‑day, 30‑day, 60‑day, or 90‑day, depending on situation).
2. If tenant does not comply or leave, file an unlawful detainer lawsuit in San Diego County Superior Court.
3. Tenant may respond; if they do, there’s a hearing or trial.
4. If you win, court issues a writ of possession.
5. Sheriff performs the lockout.

Self-help eviction is illegal:

• You may not change locks, remove doors, shut off utilities, or remove possessions to force a tenant out.
• Doing so can result in damages, penalties, and attorney’s fees.

Because the rules change often and vary with property type and location, most San Diego landlords use an attorney or property manager for evictions.
