Rent & eviction protection

Is 524 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 1907
2 or more units
30 units
Property type
Multi-Family Residential

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1907
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 524 Guerrero St building, constructed in 1907, is a four-story, 30-unit multi-family residential property located in Mission Dolores. The building has undergone several significant safety and maintenance upgrades over the past decade, including the completion of mandatory soft-story seismic retrofitting in 2014, fire alarm system upgrades in 2021, and most recently, exterior stair repairs in 2023. The property has a documented history of addressing various structural and safety issues, such as multiple stair repairs, dry rot remediation, and roofing work. Notable incidents include two concerning ceiling collapse incidents in 2007 related to water damage, and a 1998 carbon monoxide issue with a dryer that was promptly addressed.

The building has maintained regular compliance with safety regulations, as evidenced by the completion of a voluntary fire alarm system replacement in 2021 and a new boiler installation in 2011. Recent fire safety inspections in 2023 identified a sleeping area requirement violation, though this appears to have been promptly addressed. The property has experienced periodic issues requiring attention, including elevator problems documented in 2006, and various maintenance concerns that have generally been resolved through proper channels. Recent 311 calls primarily relate to parking enforcement and street maintenance issues rather than building-specific concerns. While the building has faced its share of challenges over the years, the current record shows an active management approach to maintaining safety and compliance with city regulations.

Risk rating

How 524 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

Grade A–B — Low risk

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

Grade C — Moderate risk

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

Grade D–F — High risk

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