South of Market, SF 94103 3522068 3 units · 3 fl · 1907

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 1625-1629 Folsom 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

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 three-story multi-family residential building at 1625-1629 Folsom Street, owned by Navarro Family Living Trust, was constructed in 1907 and contains three units. The property experienced significant safety-related issues in July 2011, when multiple violations were documented regarding fire safety equipment, including missing smoke detectors and fire extinguishers, though these violations were resolved by October 2011. A previous routine safety inspection from May 2008 also raised concerns about fire extinguishers within the units. The building underwent street space permit processes in July 2012.

Recent external maintenance issues include a collapsed sidewalk reported in March 2024, which was resolved but noted as a duplicate case requiring attention from the Water Department. The property has experienced recurring street cleaning challenges, with multiple reports of loose garbage in 2020-2021, and there have been two documented instances of driveway blocking, most recently in November 2021. Other street maintenance issues have included hazardous materials (glass) in January 2021 and historical sidewalk problems noted in December 2018 for both lifted and damaged utility vault frames, though these were resolved promptly. A potential overcrowding or illegal hotel use complaint was filed in July 2011, but this was also marked as resolved by October 2011.

Risk rating

How 1625-1629 Folsom 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
32ndpercentile

Out of 430 buildings in this neighborhood, 292 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
