San Diego Landlord-Tenant Laws to Know Before Buying a Rental Property in 2026

What landlord-tenant laws in San Diego in 2026 do you need to understand before buying a rental property, including just cause eviction, rent control, and tenant relocation fees?

San Diego rental investors in 2026 face two layers of regulation: California’s AB 1482 statewide tenant protections plus the City of San Diego’s stricter local Tenant Protection Ordinance, each with distinct rules on eviction, rent caps, and relocation costs.

Why San Diego Landlord-Tenant Laws Matter for Investors Right Now

If you are looking at buying a rental property in San Diego in 2026, the legal framework around tenants is more complex than it was even three years ago. You are not just dealing with one set of rules. You are navigating state law, a local city ordinance that is deliberately stricter than state law, and a handful of brand-new compliance requirements that took effect January 1, 2026.

Here is the core issue: a misstep on any of these can cost you thousands of dollars. Imagine planning a renovation on a newly acquired North Park fourplex only to discover you owe each tenant two months’ rent in relocation assistance before you can start work. That is real money, and I have seen investors blindsided by it.

With 16 years of experience as a broker associate at REAL Brokerage and over 275 closed transactions across San Diego County, I walk my investor clients through every one of these legal layers before they write an offer. A cloudy mind can’t make decisions, so let me lay this out clearly.

How AB 1482 Rent Control Works in San Diego in 2026

California’s Tenant Protection Act, AB 1482, is the statewide baseline. It limits how much you can raise rent and restricts the reasons you can ask a tenant to leave. It applies to most residential rental properties built more than 15 years ago, which means any building completed before January 1, 2011 is covered in 2026.

The Rent Cap You Need to Budget Around

The annual rent increase cap under AB 1482 is calculated as 5% plus the local Consumer Price Index, with an absolute ceiling of 10%. For San Diego County through July 31, 2026, the allowable increase is 8.8%. That sounds generous, but remember: you cannot bank unused increases from prior years. Each annual cycle resets.

What does that actually mean for your investment spreadsheet? If you are acquiring a property with below-market rents, you cannot simply jump to market rate in one move. You are capped at 8.8% per year, which means bringing a significantly underpriced unit to market rent could take you several years.

The 15-Year Rolling Window Trap

Here is something that catches even experienced San Diego investors off guard. The 15-year age exemption is not a fixed date. It rolls forward every January 1. A building that was exempt last year because it was only 14 years old is now covered. You need to track your building’s certificate of occupancy date annually. I tell my clients to put a calendar reminder on it because the consequences of missing that threshold are significant.

Just Cause Eviction Rules in San Diego: State vs. City

This is where San Diego gets tricky, and where I spend the most time educating investors.

State-Level Just Cause Under AB 1482

Under California law, once a tenant has lived in your unit for 12 months or more, you cannot terminate their tenancy without a legally recognized reason. Those reasons fall into two categories.

At-fault causes (the tenant did something wrong):

• Non-payment of rent
• Breach of material lease terms
• Nuisance, waste, or criminal activity on the property
• Refusing to sign a lease renewal on substantially similar terms
• Unauthorized subletting or refusing lawful owner entry

No-fault causes (unrelated to tenant behavior):

• Owner or close family member move-in
• Withdrawal of the unit from the rental market
• Substantial remodel requiring vacancy
• Compliance with a government order

No-fault evictions carry a financial obligation, which brings us to relocation fees.

The City of San Diego’s Stricter Ordinance

If your rental property falls within the City of San Diego limits, and most properties in neighborhoods like North Park, Mission Hills, Kensington, Mira Mesa, and Scripps Ranch do, the local Tenant Protection Ordinance applies on top of state law. It went into effect June 24, 2023, and it is intentionally more protective.

The two critical differences every investor needs to internalize:

• Just cause protections begin on Day 1 of the tenancy, not after 12 months like under state law
• Relocation assistance for no-fault evictions is two months’ rent, not one month

So if you are buying a condo in North Park, where the median condo price sits at $495,000, and your tenant is paying $2,400 a month, a no-fault eviction under the city ordinance means you owe $4,800 in relocation assistance before that tenant leaves. Multiply that across a multi-unit building and the numbers add up fast.

Tenant Relocation Fees in San Diego: What They Actually Cost You

One investor I worked with recently was evaluating a small multi-unit property near 30th Street in North Park. The plan was to renovate units as they turned over to capture the neighborhood’s strong appreciation (values in 92104 are up roughly 12% year over year). The buildings along that corridor are older, well within the 15-year AB 1482 threshold, and squarely within city limits.

When we mapped out the relocation costs for a substantial remodel scenario across four occupied units, the investor was looking at potentially eight months’ worth of aggregate rent in relocation fees under the city ordinance. That completely changed the renovation timeline and budget. We adjusted the strategy to phase renovations around natural lease expirations, which saved tens of thousands of dollars.

State vs. City Relocation Costs Side by Side

• AB 1482 (state law): One month’s rent, or a rent waiver for the final month of tenancy. The landlord chooses which option and must pay within 15 days of issuing the termination notice
• City of San Diego ordinance: Two months’ rent. The law requires you to pay whichever amount provides greater protection to the tenant, which means the city’s two-month standard applies whenever the property is inside city limits

This is not optional. If you skip relocation assistance, the eviction can be challenged, and you may face penalties on top of the original obligation.

Exemptions That Could Save San Diego Investors Thousands

Not every property is subject to all of these rules. Understanding exemptions is where having the right real estate broker in San Diego becomes invaluable.

Single-Family Home and Condo Exemptions Under AB 1482

A single-family home or condo can be exempt from both the rent cap and just cause provisions if the owner is not a corporation, REIT, or LLC where any member is a corporation, and if the owner has delivered a specific written notice of the exemption to the tenant. The notice uses language required by California Civil Code, and it cannot be added retroactively. If you buy a single-family rental in Rancho Bernardo or Scripps Ranch and your seller never gave the tenant that written notice, the tenant has full AB 1482 protections regardless of property type.

I always tell my clients: check the lease file carefully during due diligence. Was that exemption notice delivered? If not, factor AB 1482 compliance into your offer price and operating plan.

What About the City Ordinance?

The City of San Diego’s ordinance has its own set of exemptions that may differ from the state’s. Your property type, ownership structure, and location all matter. Properties outside city limits but within San Diego County generally follow AB 1482 alone.

New 2026 San Diego Compliance Rules for Landlords

Several new California laws took effect January 1, 2026, that affect your operating costs and obligations.

• AB 628 (Stove and Refrigerator): For any lease entered, amended, or extended in 2026 or later, your rental unit is not considered “tenantable” unless it includes a working stove and refrigerator. If an appliance is under a manufacturer recall, you have 30 days to repair or replace it
• AB 1414 (Internet Opt-Out): You must allow tenants to opt out of paying for any third-party internet subscription bundled with the tenancy. If you do not, the tenant can deduct the subscription cost from rent
• Security Deposit Cap: As of July 1, 2024, security deposits are capped at one month’s rent. Small landlords meeting specific conditions may collect up to two months

These may seem like small details, but they add up. Having worked alongside investors on flips and remodels for years, I can tell you that operational details like appliance compliance and security deposit rules are exactly where landlords get tripped up during turnover.

Frequently Asked Questions About San Diego Landlord-Tenant Laws in 2026

Does the San Diego rent cap apply to all rental properties?

No. Properties built within the last 15 years, owner-occupied duplexes, and properly noticed single-family homes and condos owned by individuals are among the most common exemptions. In 2026, buildings completed after January 1, 2011 are generally exempt from AB 1482’s rent cap and just cause provisions.

What is the maximum rent increase allowed in San Diego in 2026?

The AB 1482 cap for San Diego County through July 31, 2026 is 8.8%, calculated as 5% plus the local Consumer Price Index. This applies to covered properties only. The absolute ceiling under any CPI scenario is 10%.

When do just cause eviction rules kick in under state law?

Under AB 1482, just cause protections apply after a tenant has occupied the unit for 12 continuous months. However, within the City of San Diego, the local ordinance extends just cause protections from Day 1 of the tenancy.

How much do I owe in relocation fees for a no-fault eviction in the City of San Diego?

Two months’ rent under the city’s Tenant Protection Ordinance. State law requires only one month, but the city ordinance applies the higher amount for properties within city limits.

Can I avoid relocation fees by waiting for the lease to expire?

Not necessarily. Under just cause eviction rules, you still need a qualifying reason to terminate the tenancy, even at lease expiration. Simply choosing not to renew without just cause is not permitted for covered units.

Does my ownership structure affect which laws apply?

Yes. If you hold property through a corporation, REIT, or LLC with a corporate member, the single-family and condo exemptions under AB 1482 do not apply. Individual ownership or certain trust structures may preserve your exemption eligibility.

Are properties in Rancho Bernardo or Poway subject to the City of San Diego ordinance?

Poway is a separate city with its own jurisdiction, so the City of San Diego ordinance does not apply there. Parts of Rancho Bernardo fall within City of San Diego limits, so you need to verify your specific property’s jurisdiction.

What happens if I do not provide the AB 1482 exemption notice in the lease?

The exemption does not apply, even if the property otherwise qualifies. Your tenant retains full rent cap and just cause protections. This notice cannot be added retroactively to an existing tenancy.

Do the new 2026 appliance requirements apply to existing leases?

AB 628 applies to leases entered into, amended, or extended on or after January 1, 2026. If you have a multi-year lease signed before that date with no amendments, it may not yet apply, but any renewal or modification triggers the requirement.

Should I consult an attorney before buying a rental property in San Diego?

I strongly encourage it. One layer of protection I provide to my buyer clients is a complimentary attorney review of contracts and disclosures, covered by me, even if escrow cancels. For investment properties with tenants in place, legal guidance on lease compliance is essential.

The Bottom Line on San Diego Rental Property Laws in 2026

Buying a rental property in San Diego in 2026 is a strong long-term play. The county median is $925,000, inventory remains tight, and neighborhoods like North Park and Mission Hills continue to appreciate. But your returns depend on understanding the legal framework before you close.

Know which laws apply to your specific property. Budget for relocation costs. Verify exemption notices in the lease file during due diligence. And factor in the new 2026 compliance requirements.
