TL;DR
In San Francisco, landlords must give 60 days' written notice before a rent increase of more than 10% within any 12-month period. Increases of 10% or less need only 30 days' notice under California Civil Code 827. San Francisco's rent ordinance layers additional limits on top of this for most units built before June 1979.
How much notice does a landlord have to give for a rent increase in San Francisco?
California Civil Code Section 827 sets the baseline: if a rent increase, combined with any other increases in the prior 12 months, totals 10% or less of the lowest rent charged during that period, the landlord owes the tenant 30 days' written notice. If the cumulative increase is more than 10%, the landlord must give 60 days' written notice instead [1]. This is state law, so it applies in San Francisco the same way it applies in Fresno or Sacramento. But San Francisco stacks its own rent ordinance on top of state law for most older buildings, and that ordinance caps how much rent can go up in the first place, often to a fraction of what Civil Code 827 would otherwise allow. So the notice period question and the "how much can I raise it" question are two separate legal tracks. You need to clear both. A landlord who is only looking at the 60-day notice rule and ignoring the San Francisco Rent Board's annual allowable increase percentage is going to end up with an illegal rent increase notice regardless of how much notice they gave.
What counts as a rent increase over 10% versus 10% or less?
The 10% threshold in Civil Code 827 is cumulative over a rolling 12-month period, not per notice. If you raised rent 5% eight months ago and now want to raise it another 6%, that's 11% total in the trailing 12 months, which triggers the 60-day requirement even though neither increase alone crossed 10% [1]. The percentage is measured against "the lowest rent charged at any time during the 12 months prior to the effective date of the increase," per the statute's language, not against the current rent before this specific bump [1]. That distinction matters if you offered a temporary discount or concession at some point in the past year. In San Francisco, this calculation is almost academic for rent-controlled units, because the Rent Board's annual allowable increase is set well under 10%. For the March 2025 to February 2026 cycle, the Rent Board set the allowable annual increase at 1.7%. A landlord proposing anything close to a 10% jump on a covered unit is very likely violating the local ordinance's percentage cap long before the 60-day notice question even comes up.
Does San Francisco rent control override the state 60-day notice rule?
No. San Francisco's rent ordinance (Administrative Code Chapter 37) restricts how much rent can increase for units it covers, roughly those built before June 13, 1979, in structures with sufficient units and not otherwise exempt [2]. It does not replace the state notice-period rule in Civil Code 827. So you still follow the 30-day or 60-day notice rule based on the size of the increase, and separately you cannot exceed the Rent Board's annual allowable percentage for units under the ordinance. Landlords of newer construction, single-family homes, and condos that qualify for the Costa-Hawkins exemption from rent control still must follow Civil Code 827 for notice timing, even though their rent amount itself isn't capped by the local ordinance. If you're unsure whether your unit is covered by San Francisco's rent ordinance, the Rent Board's fact sheets on covered and exempt units are the place to check before sending any increase notice, confirm with your city rental licensing office or the Rent Board directly for your specific building.
How does a landlord deliver a valid rent increase notice?
California law requires the increase notice to be in writing and to state the amount of the new rent and the date it takes effect [1]. Verbal notice, a text message alone, or a casual conversation doesn't satisfy the statute. Delivery method affects your notice period math. If you serve the notice by mail rather than handing it to the tenant personally, Code of Civil Procedure Section 1013 adds 5 calendar days to the notice period for service within California [3]. Many landlords miss this and end up with a technically short notice if they mailed a 60-day notice and counted only 60 days from the mailing date. Best practice, and this isn't legal advice, just what avoids disputes: serve in person when you can, keep a signed and dated copy or a certificate of mailing, and calendar the effective date conservatively. If a tenant challenges timing later, you want a paper trail showing exactly when and how the notice went out.
What can a landlord look at during a rental inspection in California?
California doesn't have one statewide rental inspection law the way it has one rent notice statute. Instead, individual cities and counties run their own proactive rental inspection programs, and habitability itself is governed by California Civil Code Section 1941.1, which lists the conditions a rental unit must meet, effective weatherproofing, working plumbing, heating, and electrical systems, and free of vermin, among others [4]. During a routine or complaint-based inspection, an inspector is generally checking for these same categories: smoke and carbon monoxide detectors, working exits, electrical hazards, plumbing leaks, mold, pest infestations, and general structural safety. Inspectors are not typically there to evaluate your furniture or personal items in a tenant's unit; they're checking the building systems and code compliance items tied to the jurisdiction's housing code. Who is responsible for the walk-through itself varies by city and by lease. In many California cities with mandatory rental inspection programs, the property owner or their agent must be present or make arrangements for access, and the tenant cannot unreasonably refuse entry when proper notice (typically 24 hours under Civil Code Section 1954) has been given [5]. If your city runs a licensing or inspection program, check that specific department's inspection checklist rather than assuming it matches another city's.
What is landlording, and what is a landlord, exactly?
A landlord is the owner (or an owner's authorized agent) who rents real property to someone else, the tenant, in exchange for rent. "Landlording" is the informal term for the ongoing job of managing that relationship: collecting rent, maintaining the property, handling repairs, following notice and eviction laws, and staying compliant with local licensing or registration rules. It sounds simple until you're the one doing it. A landlord with one unit in San Francisco is still bound by the same Civil Code 827 notice rules, the same habitability standards under Civil Code 1941.1, and potentially the same Rent Board registration and petition process as a landlord with fifty units. The scale is different; the legal exposure per unit is not. If you're new to this, the practical version of landlording is less about knowing every statute cold and more about knowing where to look things up before you act, your city's rent board or housing department, your state's civil code, and (if the building is old enough) the local rent ordinance.
How do you become a landlord and how do you get started right?
There's no license required just to own rental property in most of California, but there often is a license or registration required to legally rent it out in cities with mandatory rental programs. The sequence that avoids the most headaches: confirm the property is legal to rent (zoning, unit count, any prior code violations), register with your city's rent board or rental registry if one applies, get a lease in writing, and understand the notice and habitability rules before you ever collect a security deposit. San Francisco requires most landlords of rent-controlled units to register with the Rent Board and pay an annual per-unit fee that funds the Rent Board's operations; the exact current fee and any city business registration requirements should be confirmed with your city rental licensing office, since these figures are adjusted periodically. A lot of new landlords skip the paperwork step and go straight to finding a tenant. That's backwards. Get your compliance ducks in order first, because a rental registered late, or a unit rented without required inspections, tends to cost far more in fines and legal fees than doing it right from day one. If you want a structured way to organize the registration, inspection, and lease-readiness paperwork before you list a unit, a rental packet builder can help you track what's due and when, separate from any specific city's forms.
What rights do tenants have without a signed lease?
A tenant without a written lease still has full legal protection; California law doesn't require a written lease for tenancy rights to exist. If a tenant pays rent and the landlord accepts it, a periodic tenancy (usually month-to-month) is created by law, and standard protections apply: the right to a habitable unit under Civil Code 1941.1, the right to proper notice before entry under Civil Code 1954, and the right to the same rent-increase notice periods under Civil Code 827 [1] [4] [5]. Without a written lease, a lot of terms default to state and local law rather than a negotiated agreement, notice to terminate, for example, generally follows the same 30- or 60-day rules used for rent increases, based on how long the tenant has lived there and local ordinance requirements. In a rent-controlled city like San Francisco, an oral month-to-month tenancy in a covered building is still subject to the Rent Board's just-cause eviction protections and the annual allowable rent increase, even with nothing in writing. Landlords sometimes assume no lease means no rules. That's not how it works; it usually means fewer negotiated terms and more reliance on statutory defaults, most of which favor tenant stability.
Why do landlords require renters insurance?
Renters insurance protects the tenant's personal belongings and gives the tenant liability coverage if they accidentally cause damage or someone is injured in the unit; it is not the same as the landlord's own property insurance, which typically covers only the building structure, not tenant possessions. Landlords require it, when they do, mainly to shift liability exposure. If a tenant's cooking fire, overflowing bathtub, or dog bite leads to a lawsuit, a renters policy (commonly with liability limits around $100,000 to $300,000) can cover the claim instead of it landing entirely on the landlord's own liability policy. It also reduces disputes over who pays when a tenant's furniture or electronics are damaged by a covered peril, since the tenant has their own claim path instead of expecting the landlord to replace their belongings. California law doesn't mandate renters insurance statewide, so any requirement comes from the lease itself, not a state statute. If you require it, that requirement and the minimum coverage amount need to be written into the lease clearly, since a landlord generally cannot penalize a tenant for something the signed lease didn't actually obligate them to do.
What can't a landlord do, and does Ohio's list apply here?
Readers researching notice rules sometimes land on Ohio-specific landlord restriction lists, but Ohio law and California law are not interchangeable, so it's worth being direct about the difference. Ohio's landlord-tenant law is codified separately in Ohio Revised Code Chapter 5321, which covers things like a landlord's duty to maintain fit and habitable premises and specific limits on entry and retaliation [6]. It does not set rent increase notice periods the way California's Civil Code 827 does, and it has nothing to do with San Francisco's rent ordinance. In California specifically, a landlord cannot raise rent without the required 30- or 60-day notice under Civil Code 827, cannot enter a unit without proper notice (generally 24 hours) except in emergencies under Civil Code 1954, cannot retaliate against a tenant for exercising legal rights under Civil Code 1942.5, and, in San Francisco, cannot exceed the Rent Board's annual allowable increase on a covered unit or evict without a just cause listed in the local rent ordinance. If you're operating in Ohio, the equivalent research should start with ORC 5321, not California code. The two states' rules genuinely don't overlap, and applying one state's percentage or notice rule in the other jurisdiction is a common and avoidable mistake.
What happens if a landlord gives the wrong notice period?
A rent increase notice that doesn't meet the 30- or 60-day requirement is generally not enforceable on its stated effective date. Courts and rent boards have treated defective notice as ineffective, meaning the old rent amount stays in force until a properly compliant notice is served and the correct number of days passes [1]. In San Francisco, a defective rent increase notice on a covered unit can also become the basis for a tenant petition to the Rent Board challenging the increase, which can tie up the landlord in an administrative hearing over an issue that a correctly calendared notice would have avoided entirely. The fix is almost always just re-serving a correct notice and restarting the clock, which costs you time, not necessarily money, but the delay compounds if you're relying on the increased rent to hit a refinance debt-service number or cover a specific expense increase. Double-check the math (cumulative 12-month percentage), the delivery method (in-person versus mail, and the mail-day addition under CCP 1013), and the written form itself before you send anything.
How does San Francisco's rule compare to other California rent-control cities?
| San Francisco | 60 days, per CA Civil Code 827 [1] | 1.7% (March 2025 to Feb 2026) | |
|---|---|---|---|
| Oakland | 60 days, per CA Civil Code 827 [1] | Set annually by Oakland's rent adjustment program; confirm with your city rental licensing office | |
| Berkeley | 60 days, per CA Civil Code 827 [1] | Set annually by Berkeley Rent Stabilization Board; confirm with your city rental licensing office | |
| Los Angeles | 60 days, per CA Civil Code 827 [1] | Set annually by LAHD's RSO program; confirm with your city rental licensing office | The practical takeaway: the notice period is the easy part to get right because it's one statute statewide. The percentage cap is the part that trips people up because it changes yearly and differs by city. Always check the current year's allowable percentage directly with the local rent board before calculating a covered unit's increase, since a number that was correct last year is very likely wrong this year. |
The 30-day and 60-day notice thresholds under Civil Code 827 are statewide, so Los Angeles, Oakland, Berkeley, and San Francisco all follow the same notice-timing rule. What differs city to city is the annual allowable increase percentage for rent-controlled units, since each city's rent board or rent stabilization program sets its own formula, usually tied to a regional Consumer Price Index measure. | City | Notice rule for increase >10% | Recent annual allowable increase (rent-controlled units) |
Where to check before sending a rent increase notice in San Francisco
Before sending any increase notice on a San Francisco unit, confirm three things: whether the unit is covered by the local rent ordinance, the current year's Rent Board allowable percentage, and whether your increase (cumulative over the past 12 months) crosses the 10% mark that triggers the 60-day rather than 30-day notice requirement. The San Francisco Rent Board publishes annual allowable increase notices and fact sheets on covered units; that's the primary source to check rather than a general California landlord guide, since the local percentage changes and general guides go stale fast [2]. If you're managing registration, inspection scheduling, and notice paperwork across a small portfolio, keeping the underlying statutes and city-specific deadlines organized in one place saves a lot of re-Googling every time a lease renews. A rental packet builder is one way to keep that documentation ready, but the actual legal research always traces back to Civil Code 827, the local rent ordinance text, and your city's current fact sheets, not a summary.
Frequently asked questions
How much notice does a landlord have to give for a rent increase in California?
Under California Civil Code Section 827, a landlord must give 30 days' written notice for a rent increase of 10% or less in a rolling 12-month period, and 60 days' written notice if the cumulative increase exceeds 10% in that same period. This applies statewide, including in San Francisco, on top of any local rent ordinance caps.
Does the San Francisco Rent Board limit how much rent can go up each year?
Yes, for units covered by the local rent ordinance (generally buildings constructed before June 13, 1979). The Rent Board sets an annual allowable increase percentage each year; for March 2025 through February 2026 it was 1.7%. Units exempt under Costa-Hawkins, like most single-family homes and condos, follow state notice rules but not this local percentage cap.
How to become a landlord in San Francisco?
There's no state license required to own rental property, but you generally need to register with the San Francisco Rent Board if your unit is covered by rent control, comply with local business registration if required, and follow California's notice and habitability statutes. Confirm current registration steps and fees with your city rental licensing office before renting out a unit.
Who is responsible for a rental property walk-through inspection in California?
It depends on the program. In cities with mandatory rental inspection, the property owner or their agent typically arranges and often attends the walk-through, while the tenant must allow reasonable access after proper notice under Civil Code Section 1954 (generally 24 hours). Check your specific city's rental inspection program for exact responsibility and scheduling rules.
What is landlording?
Landlording is the everyday work of owning and managing rental property: collecting rent, maintaining habitability, following notice and eviction laws, handling tenant communication, and staying compliant with local licensing or rent-control rules. It applies the same legal way whether you own one unit or fifty.
What is a landlord, legally speaking?
A landlord is the property owner, or their authorized agent, who leases real property to a tenant in exchange for rent. Legally, a landlord takes on duties like maintaining habitable conditions under Civil Code 1941.1 and following notice requirements for rent changes and entry under Civil Code 827 and 1954.
What rights do tenants have without a lease in California?
A tenant without a written lease still has full legal protection under California law. Paying and accepting rent creates a month-to-month tenancy by default, with rights to habitability under Civil Code 1941.1, notice before entry under Civil Code 1954, and standard rent-increase notice periods under Civil Code 827.
How to be a landlord without breaking rent control rules?
Register with your city's rent board if the unit is covered, check the current year's allowable increase percentage before raising rent, use the correct 30- or 60-day notice period under Civil Code 827, and keep written records of all notices served. Local rent ordinance rules change yearly, so recheck the percentage every cycle.
Why do landlords require renters insurance?
Renters insurance covers the tenant's belongings and gives them personal liability coverage, protecting the landlord from claims over tenant-caused damage or injury that the landlord's own building policy doesn't cover. It's not required by California state law; any requirement has to come from the signed lease itself.
What can a landlord look at during an inspection?
Inspectors and landlords conducting a unit walk-through generally check habitability items: smoke and carbon monoxide detectors, plumbing, heating, electrical systems, structural safety, and pest or mold issues, per standards like California Civil Code 1941.1. They're not there to inspect a tenant's personal belongings beyond what's needed to assess these conditions.
What can a landlord not do in Ohio, and does that apply in San Francisco?
Ohio's landlord restrictions come from Ohio Revised Code Chapter 5321, a completely separate law from California's Civil Code. Ohio rules on habitability, entry, and retaliation do not apply to San Francisco landlords; California landlords should reference Civil Code 827, 1941.1, and 1954, plus San Francisco's own rent ordinance.
Does mailing a rent increase notice change the notice period?
Yes. Under California Code of Civil Procedure Section 1013, mailing a notice within California adds 5 calendar days to the required notice period compared to personal delivery. A landlord who mails a 60-day increase notice should count from the mailing date plus that added time to avoid a short notice.
What happens if a San Francisco landlord gives the wrong number of days' notice?
A rent increase notice that doesn't meet the 30- or 60-day requirement under Civil Code 827 is generally not enforceable as written. The prior rent stays in effect until a corrected notice is served and the full required notice period runs again, and a tenant on a covered unit can also petition the Rent Board over a defective notice.
