Most landlords spend a lot of energy finding a good tenant. Then the lease ends and they have no idea what to do next.
Do you raise rent? By how much? Do you send paperwork or just have a conversation? What are you legally allowed to do? These are the questions that trip people up, and getting them wrong in a California market can mean rolled-back increases, legal disputes, or a vacant unit costing you $150–$250 a day in lost income. If you want to get the fundamentals right before you ever touch a renewal, our complete guide to lease agreements for landlords is a good starting point. But once a tenant is in place and renewal season is coming, the decisions get specific fast. Here's what we've learned across 13 years and 1,600 units in Southern California.

Start With the Numbers, Not Your Gut
The first mistake we see owners make is deciding whether to raise rent based on how they feel about the tenant relationship instead of what the numbers actually say.
We get it. A quiet tenant who pays on time is a rare thing. But feelings don't pay the mortgage.
We had a client whose 3-bedroom home in Irvine was rented at $3,200 a month. Market comps pulled through AppFolio were showing comparable units leasing at $3,600–$3,800. She hadn't raised rent in two years. The gap was $400 a month — $4,800 a year — and she genuinely had no idea.
Before any renewal conversation, pull your data:
- Current rent vs. market rent: What are comparable units actually leasing for right now?
- How long the tenant has been in place: Longer tenure often signals a tenant who values stability, which matters in the math.
- What turnover would actually cost you: Cleaning, paint, carpet, vacancy, re-leasing — in the LA/OC market, that typically runs $3,000–$6,000 for a single-family home.
- Your legal cap: AB 1482, the LA RSO, or your city's specific rules may limit how much you can increase regardless of what the market is doing.
“Cleaning, paint, carpet, vacancy, re-leasing — in the LA/OC market, that typically runs $3,000–$6,000 for a single-family home.”
Run the numbers first. Then make a decision.
Know Which Rules Apply to Your Property
California landlord-tenant law is layered. The rules that apply to your property depend on when it was built, where it's located, and who owns it.
AB 1482: The Statewide Baseline
AB 1482 caps annual rent increases at 5% plus the local CPI for most multi-family properties that are at least 15 years old, meaning buildings constructed before approximately 2011 are covered as of 2026. In Los Angeles, the 2024 CPI adjustment used for AB 1482 calculations came in at 3.0%, which means the AB 1482 ceiling for a covered LA County property was 8.0% that year (or 8.9% under the City of Los Angeles's calculation). Push past that without documentation, and you're exposed.
Single-family homes may be exempt from AB 1482 — but only if you've served the tenant a proper written exemption notice. Miss that notice and your SFR may fall under the cap by default. We've seen owners assume they're exempt when they're not.
The LA Rent Stabilization Ordinance
If you own a multi-family property (two or more units) in the City of Los Angeles that was first built on or before October 1, 1978, the RSO applies. These properties have annual allowable increase percentages set by the city — separate from AB 1482 — and the city has kept those percentages low following COVID-era restrictions. Raising rent above the RSO allowance can mean fines, rollback orders, and tenant lawsuits.
Orange County Cities: More Flexibility, Same State Rules
Cities like Irvine and Huntington Beach don't have local rent control ordinances, though Costa Mesa adopted a Just Cause Residential Tenant Protections Ordinance in 2023. AB 1482 is your primary guardrail there. Owners in those submarkets generally have more room on renewals than their counterparts in the City of LA — but the statewide notice requirements still apply to everyone.
Understand the Notice Requirements Before You Send Anything
California law sets two notice thresholds for rent increases:
- Under 10% increase: 30 days written notice for rent increases of 10% or less
- Over 10% increase: 90 days' written notice required
The 10% threshold is measured against the lowest rent charged at any time during the 12 months prior to the effective date of the rent increase — not just the current rent. So if you dropped rent at some point in the past year and are now trying to bring it back up, the calculation might push you into the 90-day window even if you didn't expect it to.
Send the wrong notice period and the increase doesn't take effect when you planned. It's an easy mistake that costs weeks of income.
The Case for a Phased Increase
If a tenant is significantly below market, a large one-time jump carries real risk. Even in a tight market like Orange County, where year-over-year rent growth has been running around 2–4%, a sudden 15% increase hits differently than a structured, phased approach.
Here's how that played out for the Irvine owner we mentioned earlier. Gabby Lopez, one of our property managers, structured a phased increase rather than going straight to market in one shot: $200 at renewal and another $150 six months later. The tenant stayed, and the owner recovered roughly $4,200 in annual revenue — no vacancy, no turnover, no $3,000+ cleaning bill.
That kind of approach works especially well in Irvine, where lease renewals timed for August–September can align with UC Irvine move-in demand. Price it right and time it right, and you fill fast at asking.
When Keeping Rent the Same Is Actually a Strategy
This is the take most property management articles skip: sometimes not raising rent is the right call.
But there's a difference between deciding not to raise rent and just forgetting to.
We've talked to owners who let rent sit flat for three or four years without running a single comparable. That's not a strategy — that's inertia. A long-term tenant paying $200 below market can be worth keeping, but only if you've made that choice deliberately and documented it.
Here's the math: if turnover costs you $4,500 and the annual revenue gap is $2,400, the tenant has to leave and the unit has to sit vacant for less than two months before you've lost more than you would have gained from the increase. In a slow leasing window — say, a detached home in Torrance listing in November — that's a real risk.
Choosing not to raise rent is a legitimate business decision. Defaulting to it because paperwork feels awkward is not.
Just Cause Eviction Changes the Renewal Game
One thing that catches owners off guard in California: once all tenants have lived in the unit for 12 months, AB 1482's just cause eviction provisions kick in for covered properties — or sooner if at least one tenant has been there for 24 months, even if others have not yet reached 12 months. You can no longer simply decline to renew the lease without a qualifying reason.
This makes the renewal conversation more than a pricing decision. It's also a legal one. If you want to regain possession of the property — for a major renovation, to move in a family member, or to sell — you need to understand which just cause categories apply and what documentation you'll need.
The owners who navigate this smoothly are the ones who treat every renewal as a formal process, not a handshake extension. One client put it well: "Gabby always helps me make the best decisions to improve the value of my property and approaches everything with professionalism and attention to detail." That kind of partnership is what keeps a renewal from turning into a legal problem.
What Good Renewal Documentation Looks Like
A renewal conversation without a paper trail is a liability.
Every renewal should include:
- A written notice sent with the correct notice period (30 or 90 days depending on the increase amount)
- A signed lease addendum or new lease agreement reflecting the updated terms
- A current inspection report with photos establishing the property's condition
- A record of the comparable market data you used to set the new rate
That last point matters more than people realize. We worked with an owner who self-managed a duplex in Long Beach and had been doing verbal renewals for years. When a tenant moved out, he had no documented baseline for the unit's condition and lost a small claims dispute over the security deposit. HCM's two documented annual inspections — with photos delivered directly to the owner — give owners in our portfolio the paper trail to defend any deduction or renewal position.
Our vendor partner handles the inspection photography for these reports, and the turnaround is fast enough that owners have current condition documentation well before renewal season hits.
Timing Your Renewal Outreach
Don't wait until the lease expires to start the conversation. In most cases, we reach out 60–90 days before the end of the term.
That window gives you enough time to:
- Pull current market comps and set the new rate
- Send the legally required written notice before the deadline
- Give the tenant a reasonable amount of time to decide without feeling blindsided
- List the property for backup showings if the tenant decides to move on
In practice, early outreach also signals to a good tenant that you're organized and attentive. Tenants who feel managed professionally are more likely to renew. We track every touchpoint through LeadSimple, which means nothing slips through the cracks when multiple renewals are happening across a portfolio at the same time.
What to Do if the Tenant Wants to Move Out
Not every renewal ends in a renewal. Sometimes the tenant is ready to go, and that's okay.
The moment a tenant gives notice, the clock on your vacancy cost starts ticking — $150 to $250 a day in lost rent alone, not counting the turnover expenses. Speed matters.
Get the unit relisted within days of receiving notice, not after the tenant leaves. Use that overlap to schedule showings, collect applications, and run screening so a qualified tenant is ready to sign on or near the move-out date. Every tour and showing should be tracked with a guest card so pricing decisions are based on actual market response, not guesswork.
The owners in our portfolio who move through turnovers fastest are the ones who treat every vacancy as a revenue event that started the day the notice came in — not the day the keys were handed back.
Frequently Asked Questions
How much notice do I need to give before raising rent in California?
California requires 30 days' written notice for rent increases of 10% or less, and 90 days' written notice for increases greater than 10%, with both thresholds measured against the lowest rent charged to that tenant at any time during the prior 12 months. The notice must be in writing — a text or verbal heads-up does not satisfy the legal requirement.
Does AB 1482 apply to single-family homes?
It can. Single-family homes owned by individual landlords may be exempt from AB 1482's rent cap, but only if the tenant was properly served a written exemption notice. If that notice was never provided, the property may be treated as covered by the cap regardless of its ownership structure.
What happens if I raise rent above the legal limit?
The tenant can file a complaint with the local housing authority, and you may be required to roll back the increase, issue a corrected notice, and restart the notice clock. In AB 1482-covered properties, excess increases can also expose you to legal liability. Getting the calculation right before you send anything is a lot cheaper than fixing it afterward.
Is it better to do a month-to-month or a fixed lease at renewal?
It depends on your goals. A fixed-term lease gives you predictability and locks the tenant in for another 6–12 months. Month-to-month gives you more flexibility if you're considering selling, renovating, or adjusting the rent again soon. The trade-off is that month-to-month arrangements can feel less stable to good tenants, and in California, just cause eviction rules still apply after 12 months of occupancy regardless of the lease structure.
How do I know if my rent is actually below market?
Pull active listings for comparable properties within a 1–2 mile radius — similar bed/bath count, condition, and amenity set. AppFolio's market analysis tools can help if you're working with a property manager. If your rent is more than 5–8% below the lowest comparable active listing, you're leaving money on the table and should factor that into your next renewal conversation.
What if my tenant refuses to sign the renewal paperwork?
If a fixed lease expires and the tenant stays without signing a new agreement, in most cases the tenancy converts to month-to-month under the original lease terms. That's not necessarily a crisis, but it's also not the same as a documented renewal. A tenant who won't engage with the renewal process is worth monitoring closely — it can sometimes signal an intent to vacate soon.
