Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1143-1149 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
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 1143-1149 Guerrero Street is a two-story, four-unit multi-family residential building located in Noe Valley, constructed in 1908 and currently owned by Luis Muela & Matilde Gomez. The building's most significant structural work was completed in early 2001, when earthquake upgrades were performed at the ground floor level at a cost of $18,000. More recent improvements include a sewer replacement from the property line to the curb completed in 2009. The building has undergone several modifications and faced various compliance issues over its history, including a 2012 complaint regarding an unpermitted deck construction, and multiple fire safety violations in 2011 related to fire extinguisher maintenance.

The property has an established history of maintenance and compliance actions, with resolved violations including handrail repairs and self-closing door requirements from 2001. Three planning records show attempts to address rear yard non-compliance issues, with an approved variance for reconstructing existing rear porches and stairs. Recent municipal service requests primarily pertain to external maintenance issues such as tree maintenance and street cleaning, with the most recent being resolved cases from 2023 and 2024. While the building has had various maintenance and compliance issues over the years, all cited violations and complaints have been addressed and closed, indicating that current property management is responsive to regulatory requirements. The most recent significant structural work was completed over a decade ago, suggesting the building's major systems have remained stable since the 2001 earthquake retrofitting, though no recent building permits have been noted in the available records.

Risk rating

How 1143-1149 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
30thpercentile

Out of 1879 buildings in this neighborhood, 1315 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
