Rent & eviction protection

Is 377-383 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 1910

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 three-story multi-family residential building at 377-383 Guerrero St, owned by Chang Sing & Chin Bee Choo, was constructed in 1910 and contains three units. The property has undergone several significant changes over the years, most recently including a permitted change of use from a tattoo shop to a dog daycare in May 2024. This follows a lengthy history of commercial space conversions, including a retail to personal service change in 2006. The building's maintenance record shows some concerning patterns, particularly regarding fire safety compliance. Between 2021 and 2024, there were multiple fire safety violations recorded, including issues with blocked exits, extinguishers, alarm systems, and multiple fire code violations in 2017 and 2024. While these violations were generally corrected promptly, their recurring nature suggests ongoing compliance challenges.

The property has experienced several notable maintenance issues, including a serious plumbing situation in 2008 involving black sludge and extensive bathroom decay, though this was reportedly addressed promptly. More recently, there have been complaints filed in 2024 regarding potential illegal commercial units and unauthorized changes of use, though these complaints are currently listed as not active. The building's recent history shows some ongoing exterior maintenance needs, as evidenced by multiple 311 calls in early 2025 regarding graffiti and debris, along with an open complaint about a damaged tree. While there have been historical fire incidents recorded, none resulted in civilian injuries, and the building has maintained its residential classification despite the commercial space conversions. The property's fire safety compliance history shows a pattern of violations being addressed, though the frequency of such violations raises concerns about ongoing maintenance practices.

Risk rating

How 377-383 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
22ndpercentile

Out of 799 buildings in this neighborhood, 623 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
