Rent & eviction protection

Is 426-428 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 1908

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.

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 426-428 Guerrero Street is a two-story, two-unit multi-family residential building located in Mission Dolores, constructed in 1908 and currently owned by Michael P Cohrs & Gregory A. The building has undergone several significant improvements over the past two decades, with the most recent being a voluntary structural upgrade completed in 2021 at a cost of $75,000. Other notable improvements include a deck replacement in 2018 ($8,500), multiple kitchen and bathroom remodels between 2003-2005 totaling over $110,000, and the installation of an EV charging station in 2014. However, the building has experienced several concerning issues, particularly in 2020, including complaints about mold in a bedroom closet, inadequate smoke/CO detector compliance, and multiple fire code violations related to doors, exits, and illumination, though these violations were subsequently abated. A building violation from 2000 regarding unauthorized window replacement and sidewalk blockage was also resolved.

Recent activity at the property has included multiple complaints about blocked driveways, with seven such incidents reported between September 2024 and January 2025, though enforcement officers were usually unable to locate the offending vehicles. There have also been two tree-related incidents reported recently, including a damaged tree in October 2024 and a tree maintenance issue in January 2025. The building's maintenance history shows regular attention to major systems and safety requirements, though the 2020 fire safety violations and smoke/CO detector issues raised significant concerns about resident safety during that period. The property has generally been proactive in addressing structural and safety improvements, as evidenced by the voluntary upgrades and systematic remodeling work performed over the years.

Risk rating

How 426-428 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
45thpercentile

Out of 799 buildings in this neighborhood, 439 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Per-building complaint rate across the owner's portfolio.
