Mountain View Rent Control in 2026: Is Your Apartment Actually Covered?
If you rent in Mountain View, one number matters this year: 2.5%. That is the most your landlord can raise your rent between September 1, 2026 and August 31, 2027, if your apartment is covered by the city's rent stabilization law. If it is not covered, your ceiling is roughly three times higher. Same city, sometimes the same block, very different outcome.
Mountain View is unusual in the South Bay. San Jose has its own ordinance, while Sunnyvale, Santa Clara, Cupertino, Milpitas, and Campbell have no local cap at all. Mountain View voters passed Measure V in 2016, creating the Community Stabilization and Fair Rent Act (CSFRA). Here is how to tell whether it applies to you.
The 2026 cap is 2.5%
Each year the Rental Housing Committee sets an Annual General Adjustment (AGA), the most your rent can rise during a continuing tenancy. Recent years:
2026: 2.5% (Sept. 1, 2026 to Aug. 31, 2027)
2025: 2.7%
2024: 2.4%
2023: 5.0%
2022: 5.0%
2021: 2.0%
The formula is not discretionary. The AGA equals 100% of the change in the Bay Area Consumer Price Index from February to February, floored at 2% and capped at 5%, which is why 2022 and 2023 both landed exactly at 5.0%.
In dollars, that is real money. As of late summer 2026, RentCafe puts the average Mountain View one bedroom in the mid $3,500s, while Apartment List, which weights newer buildings more heavily, runs closer to $4,100. Older garden-style complexes, exactly the ones most likely to be stabilized, often run $2,900 to $3,400. On a $3,600 one bedroom, 2.5% is about $90 a month.
Is your apartment actually covered?
Most renters get this wrong, because the CSFRA has three tiers, not two.
Fully covered: three or more units, first occupied before February 1995. You get both the rent cap and the eviction protections. The 2.5% ceiling is yours.
Partially covered: three or more units, first occupied between 1995 and December 23, 2016. Eviction protections only. No local cap on your increase, so state law becomes your ceiling.
Fully exempt: any unit whose first certificate of occupancy came after December 23, 2016 (essentially every new building in the city), single family homes on a parcel with no other residential unit, condos, duplexes, ADUs, subsidized housing, dorms, and anything rented for under 30 days. Mobile homes fall under a separate ordinance with its own adjustment, so do not use the AGA above.
Where the covered buildings are
You can roughly read the map. Mountain View's pre-1995 stock is concentrated in the two and three story garden complexes along Rengstorff Avenue, the Latham Street and Escuela Avenue blocks, West El Camino Real heading toward Sunnyvale, and older pockets of Monta Loma, Rex Manor, Sylvan Park, and the Wagon Wheel area near Whisman. Carports, exterior stairwells, a courtyard, and no package room is a good sign you are covered.
The newer construction is just as identifiable and almost all exempt: the mid-rises around the Village at San Antonio, the East Whisman projects near Middlefield and Ellis, and anything in North Bayshore. Elevator, podium parking, amenity lounge, almost certainly not stabilized. Do not rely on looks alone, though, because much of El Camino Real has been redeveloped and a 1970s complex can sit next to a 2023 building. The certificate of occupancy date is what the law keys on, and the city's Rent Stabilization Division can confirm your status.
If you are exempt, AB 1482 is your ceiling
California's Tenant Protection Act (AB 1482) limits increases to 5% plus regional inflation, capped at 10%. For Santa Clara County, the maximum for increases effective August 1, 2026 through July 31, 2027 is 8.6%. Counties in the San Francisco CPI region, including San Mateo and Alameda, are at 8.8%, which is why advice from a friend in Redwood City may not match your situation.
Run that same $3,600 one bedroom. Covered, your increase caps near $90 a month. Exempt and under AB 1482, it can legally be about $310. That is a $2,640 difference over one year, driven entirely by when your building was finished.
AB 1482 has its own holes: housing built within the last 15 years, and single family homes and condos owned by individuals rather than a corporation or LLC, and then only if the owner served the required exemption notice. Rent a house from a corporate owner and AB 1482 likely still protects you.
Banking: why your increase can exceed 2.5%
If your landlord skipped an increase in a prior year, they can "bank" it and apply it later on top of the current AGA. The total in any one year is capped at 10% of last year's rent, and rent can still only rise once per twelve months.
Banked increases carry extra obligations. The notice must include mandatory language about banking and your right to petition, and your landlord must file a copy with the city within seven days. A notice above 2.5% with none of that language is a red flag.
Your remedy has a tight deadline. If a banked increase creates real hardship, file a Tenant Hardship Petition within ten calendar days of the effective date. Qualifying grounds include household income below 100% of area median income, or rent above 50% of household income, with a 120% threshold if your household includes someone under 18, someone 62 or older, or someone disabled. Miss the deadline and the first month stays due.
"Rent" means more than your base rent
The CSFRA defines rent broadly: parking, pet fees, storage, landlord-billed utilities, and subletting fees all count, so a new charge that was not part of your tenancy at the start is treated as a rent increase. A $75 parking fee added mid-tenancy counts against your 2.5% and cannot be stacked on top of a full AGA increase.
Ratio Utility Billing Systems are also gone for tenancies starting March 1, 2024 or later: in covered units, total rent must include utilities and your lease must say which. What you pay PG&E directly, and genuinely submetered utilities, still fall outside.
One item worth real money: move-in concessions. A free or discounted first month does not reduce your base rent. Concessions beyond that first full month do, lowering the baseline every future increase is calculated from. If you got two or three months free and your landlord has been calculating increases off the undiscounted rent, an Unlawful Rent Petition can reset the rent and recover the difference before a city hearing officer.
Your landlord must be compliant to raise rent at all
This is the most underused protection in the ordinance. A landlord can only apply the AGA if twelve months have passed since your last increase, the property is registered with the city (due each January 31), the annual Rental Housing Fee is paid ($130 per unit in 2025, and it cannot be passed through to you), there are no outstanding code violations, and you received at least 30 days written notice plus a CSFRA information sheet.
If the property is unregistered or the fee unpaid, no increase is lawful while that remains true. The city posts non-compliant properties on its rent stabilization portal, so this is checkable.
You cannot be evicted because your lease ended
Both fully and partially covered buildings have just cause protection, limited to nine reasons: failure to pay rent, breach of lease, nuisance, criminal activity, failure to give access, temporary vacancy for substantial repairs, owner move-in, withdrawal from the rental market, and demolition.
Declining to sign a renewal is not on that list. If you do not re-sign, your old terms carry over and the tenancy goes month to month. Your landlord can apply the next AGA after twelve months, but cannot terminate you for it.
If your tenancy does end for substantial repairs, owner move-in, market withdrawal, or demolition, which matters given how much of the El Camino Real corridor is being rebuilt, you may qualify for relocation assistance at or below 120% of area median income: your deposit back, help finding a replacement unit, three months of the median rent for a comparable unit plus $5,000, and another $8,000 if your household includes someone 62 or older, a disabled member, or a dependent child. You also get a first right of return at your old lawful rent if the unit comes back within five years.
Vacancy decontrol: why staying put pays
Here is the catch that shapes the whole market. Under state law, when a covered unit goes vacant the landlord can reset rent to market, and protections restart for the next tenant from that higher baseline. So a long tenancy compounds in your favor: three years of 2.5% increases on a $3,000 rent gets you to about $3,231, while the identical unit next door, re-rented after a turnover, may ask $3,600 on day one. If you are fully covered and the rent works, the math usually argues for renewing.
If your increase looks wrong
Find your building's first occupancy date. Before February 1995 with three or more units means 2.5% is your cap.
Do the arithmetic on every fee, not just base rent. Anything above 2.5% must be labeled a banked increase with the mandatory language, and you need 30 days written notice and twelve months since the last increase.
Call the Rent Stabilization Division at 650-903-6136 or email mvrent@mountainview.gov. Virtual office hours run Tuesdays 10 a.m. to noon with bilingual help, and a tenant Housing Help Center meets the first and third Thursday of each month at 298 Escuela Avenue.
The takeaway
The age of your building is one of the most consequential facts about your housing cost in Mountain View, and most renters never check it. A covered unit gives you a 2.5% ceiling, nine specific eviction reasons, relocation money if the building comes down, and a landlord who must stay registered and code-compliant to raise rent at all. An exempt unit a block away gives you 8.6% and much less. Either can be the right call, since the newer buildings trade that protection for in-unit laundry and a short walk to Caltrain. Just ask the leasing office directly whether the unit is CSFRA covered, and price in the difference before you sign. On Iris you can describe what you need in plain language and compare the two side by side.
