The rules you followed last year might already be out of date. In San Diego, staying compliant means staying current.
Why San Diego Owners Can’t Rely On State Law Alone
Most property owners assume rental law works the same way across California. San Diego breaks that assumption.
Owners here must navigate two sets of tenant protection law at the same time, a state layer and a city layer. Both have changed within the last two years. This overlap usually explains why a lease template that worked fine in 2023 now needs updating, or why a termination that would be routine just outside city limits isn’t routine at all inside them.
This gap also tends to catch San Diego landlords who manage everything themselves. If juggling all of that already feels like a full-time job, the real cost of self-managing your rental property breaks down what that time and risk is actually costing you.
What San Diego Adds on Top of State Law
California’s Tenant Protection Act, AB 1482, applies to nearly every rental in the state. It caps annual rent increases at 5% plus the local Consumer Price Index, up to 10%, and it requires just cause for eviction once a tenant has lived in a unit for 12 months.
San Diego adds its own rules on top of that. Under Municipal Code Sections 98.0701 through 98.0709, here’s what changes for you as a San Diego owner:
- Protections start on day one of the lease, not after 12 months
- No-fault terminations require relocation assistance: two months of rent for most tenants, three months if the tenant is 62 or older or living with a disability
- Many single-family rentals owned through an LLC, REIT, or corporation are covered, even ones AB 1482 alone would exempt
Whichever rule protects the tenant more is the one that applies inside city limits, and that’s the part owners based outside California or the city itself most often miss. This is also where property management compliance starts to get complicated for anyone handling it alone.
Rent Increase Notices: The Detail Most Owners Get Wrong
Rent increase laws aren’t just about staying under the cap, the notice itself has rules too.
Depending on how much you’re raising the rent, state law requires either 30 or 60 days’ written notice before the increase takes effect. San Diego’s ordinance goes a step further and requires that notice to spell out, in plain language, that the increase is subject to legal limits.
This is also where owners run into trouble with the CPI portion of the cap. The allowable percentage isn’t fixed. It shifts every year based on the local Consumer Price Index. This means a rent increase that was compliant twelve months ago might not be this year. Sending the same notice template year after year, without checking the current cap, is one of the more common ways San Diego owners end up out of compliance without realizing it.
The Compliance Gaps Owners Don’t See Coming
A few patterns show up again and again that catch owners off guard by San Diego’s tenant protection laws:
- Assuming an LLC-owned or corporate-owned property is automatically exempt from local eviction laws, when San Diego’s ordinance often covers those properties anyway
- Treating a no-fault termination like a routine notice, without calculating and including the required relocation assistance
- Reusing last year’s rent increase notice without checking whether the CPI-based cap has changed
- Managing properties in more than one San Diego County city under a single set of assumptions, when Imperial Beach, Lemon Grove, and Chula Vista each enforce their own versions of these rules
None of these mistakes are complicated on their own. They’re just easy to miss if property management compliance isn’t something you’re actively tracking, and expensive to fix after the fact.
What’s Actually Changing Right Now
San Diego’s tenant protection laws just shifted again. Here’s what’s new for San Diego landlords in 2026:
- You can’t use algorithmic software to set rent anymore. If you’ve been using a pricing tool that pulls in market data and spits out a suggested rent, you now have to make that call yourself. The state is treating automated rent-setting as a pricing coordination risk.
- You now have to return security deposits electronically if that’s how the tenant paid rent and deposit in the first place. If a tenant paid you through an app or bank transfer, you need to return their deposit the same way.
- Habitability rules now call out a working stove and fridge specifically, not just general “livable conditions.” That closes a gap owners used to lean on: a unit technically wasn’t unlivable without appliances, but now it is, which raises the bar on what you need to have in place before a tenant moves in.
- Tenants can opt out of internet subscriptions bundled into their rent. If you’ve been including internet service as a line item baked into the lease, tenants now have the right to decline it and find their own provider instead.
And it’s not just a San Diego issue anymore. Imperial Beach, Lemon Grove, and Chula Vista have each passed their own tenant protection ordinances in the last year and a half, so if your properties span more than one city, you could be following several different sets of rules at once.
The Real Risk Behind These Changes
Getting a no-fault termination wrong under San Diego’s ordinance doesn’t just slow things down, it can get expensive. You could end up paying the tenant’s attorney’s fees and extra damages on top of it, plus months of lost rent while you fix the mistake and start over.The cost isn’t always a lawsuit, either. It can be smaller and slower. A delayed turnover because a notice had to be reissued. A tenant who stays longer than planned because the paperwork wasn’t right the first time. Or a deal that stalls because a buyer’s attorney flags a compliance gap during due diligence.If you own property in more than one San Diego city, you can’t assume the rules at one address apply at the next. Catching that shift ahead of time is exactly the difference between a property manager and a property operator. One waits for a problem to surface, while the other already tracks the change before it reaches your property.
Why We Built Our Process Around This
This is one of the reasons Mendes Company exists in the form it does. We’ve never separated property management from brokerage. Owners don’t experience their investment in separate pieces, and treating compliance like someone else’s department is how these gaps happen in the first place.
We manage every property the way we’d want our own managed, proactively. Owners stay with us because the rules don’t catch them off guard. We already have.
Quick Answers for San Diego Owners
- Does San Diego’s ordinance apply to single-family homes
- Often, yes. Unlike AB 1482, which exempts many single-family homes, San Diego’s local tenant protection laws can still apply if an LLC, corporation, or REIT owns the property.
- How much notice do I need to give before a rent increase?
- Generally 30 days for smaller increases and 60 days for larger ones, under state law, plus the plain-language disclosure San Diego’s ordinance requires.
- What counts as a no-fault termination?
- Situations where the tenant hasn’t done anything wrong, like an owner move-in, a substantial remodel, or taking the unit off the rental market. These require relocation assistance under San Diego’s ordinance.
- Do these rules apply to month-to-month tenants too?
- Yes. Both AB 1482 and San Diego’s ordinance apply to month-to-month tenancies, including leases that started as a fixed term and rolled over.
How Mendes Company Stays Ahead Of These Changes
Staying current on San Diego’s tenant protection laws isn’t a once-a-year task for us. It’s built into how we manage every property.
Here’s what that looks like for owners:
- We track state and local rulemaking as it happens, not after it’s already caused a problem
- We update lease templates, notices, and termination paperwork as the rules change, so you’re not finding out about a gap mid-eviction
- Property management and brokerage live under one roof, so if a compliance question comes up around a potential sale or acquisition, we answer it with the same real-time knowledge we use to manage the property day-to-day
- You get transparent, real-time reporting so you can see exactly how we’re handling your property without having to ask
- We calculate and track rent increase timing and notice requirements property by property, so nothing goes out based on last year’s numbers
That’s what hands-off property management is supposed to mean: someone watching the details you don’t have time to.
The Bottom Line
San Diego’s tenant protection laws didn’t finish evolving when the city’s ordinance passed in 2023. Between new state requirements that took effect in 2026 and more San Diego County cities adopting ordinances of their own, the rules governing your property are more likely to change than stay the same over the next few years. Staying compliant isn’t a once-a-year task anymore. It’s an ongoing one.
