Rent & eviction protection

Is 4524-4526 Mission St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1904

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1904
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 4524-4526 Mission Street is a two-unit, two-story mixed-use building constructed in 1904, currently owned by the Peter Whitcomb Revocable Living Trust and operating as a multi-family residential building with commercial space. The building has undergone several significant maintenance and improvement projects, including re-roofing work in 2010 costing $13,000 combined for plywood installation and re-roofing, and various plumbing upgrades in 2019 (though some permits were canceled). The structure has faced multiple fire safety concerns, with violations issued in August 2023 regarding exits, fire escapes, standpipe systems, and doors. A notable fire safety violation history from July 2018 included issues with sprinklers, extinguishers, exit maintenance, and roof access, though these were subsequently abated.

The property has experienced recurring issues with graffiti, with multiple reported incidents in recent months (2024), three of which remain open or were only partially resolved. Recent maintenance concerns include a sewage back-up discharge from a catch basin in December 2024, though inspections found no significant problems. Historical complaints include a water drainage issue affecting neighboring property (2019) and a hoarding-related complaint (2016) that was noted as repeated. The building's commercial space has undergone various modifications, including electrical work for sign installation in 2007 and permits related to a bar/restaurant use (ABC Type 47) that was approved in 2018. The property has had multiple 311 calls relating to environmental issues, including offensive conditions and debris, with the most recent cases all being resolved through city services.

Risk rating

How 4524-4526 Mission St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
10thpercentile

Out of 149 buildings in this neighborhood, 134 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
