Rent & eviction protection

Is 915-917 Guerrero 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 before 1979
Built 1900

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 1900
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 three-unit multi-family residential building at 915-917 Guerrero Street, owned by 915-917 Guerrero Street LLC, is a two-story flats and duplex structure built in 1900 located in the Eureka Valley/Dolores Heights neighborhood. The building has undergone several significant improvements over the past years, with the most substantial renovation occurring in 2011 when Unit 921 received an $80,000 remodel including basement floor reframing, kitchen and bathroom updates, and electrical work. In 2010, the property addressed multiple safety concerns under Notice of Violation (NOV) requirements, including the installation of a new spiral stair at the third level, safety railings for roof access, and concrete pier repairs, all costing $15,000. Other notable improvements include a reroofing project completed in 2012 ($8,600) and recent street space permits issued in 2016.

The building's history includes one main cluster of violations from 2008, which were all abated by October 2008 and involved various safety and maintenance issues such as fire safety equipment, ventilation, handrails, and window repairs. Since then, the building has maintained relative compliance with safety regulations. There have been occasional maintenance and upgrade projects, though some permits, such as for a new furnace and bathroom rough-ins issued in 2011, are now listed as expired. A minor building complaint regarding unauthorized construction was filed in 2020 but was marked as not active. The property has experienced recurring issues with vehicles blocking driveways in 2024, resulting in multiple citations, and there was one documented gas leak incident (412) with no civilian injuries recorded.

Risk rating

How 915-917 Guerrero 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
17thpercentile

Out of 1278 buildings in this neighborhood, 1061 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
