Rent & eviction protection

Is 519 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.

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

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 11-unit, three-story apartment building at 519 Guerrero Street, owned by Connolly Exemption Trust, was originally constructed in 1922 and has undergone various renovations and faced multiple regulatory scrutiny over the years. Most recently, the building has seen significant infrastructure improvements, including the conversion of a storage room to a laundry facility completed in early 2024, along with a substantial electrical upgrade to a 400-amp service with 12 meters. The property has also made efforts to address fire safety concerns, with a 2023 upgrade to the fire alarm system and the installation of low-frequency sounders in sleeping areas to meet fire code requirements.

The building has faced several compliance challenges, particularly in recent years. In September 2023, active violations were noted regarding lead paint concerns, fire proofing materials, smoke/carbon monoxide detector compliance, and general building maintenance. A pattern of building safety issues emerged from a 2002 routine inspection, which identified problems with stairs, fire escape maintenance, security features, and fire proofing materials, though these were subsequently abated. The property has experienced regular fire safety inspections, with violations noted in 2021 regarding fire extinguisher testing, exit maintenance, and building owner contact requirements, all of which were abated. While the building's systems have been progressively upgraded, as evidenced by the recent permits and completed fire safety improvements, the active violations from 2023 indicate ongoing maintenance and compliance challenges that require attention. The surrounding area has had its share of typical urban issues, with several 311 calls recorded between 2015 and 2023 primarily related to street cleaning matters.

Risk rating

How 519 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 799 buildings in this neighborhood, 663 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
