1257 10Th Ave

Inner Sunset, SF 94122 1740012 6 units · 2 fl · 1964

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 1257 10Th Ave 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 1964
2 or more units

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 1964
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 6-unit, 2-story multi-family residential building at 1257 10th Avenue in the Inner Sunset, owned by Lai Tung-loi & Wai Ying Rev, has been maintained with several significant updates since its construction in 1964. The building's maintenance history shows consistent attention to basic infrastructure, including multiple window replacements in the early 1990s (four separate permits for aluminum window replacements between 1992-1995) and reroofing work in 1992. More recent maintenance includes two street space permits issued in July and August of 2010, though these were for minimal costs of $1 each.

The building underwent routine housing inspections in 2001 and 2010, with the 2001 inspection identifying two key safety issues that were promptly addressed within one month: the need to recharge all fire extinguishers in public areas and the requirement to provide a gas utility shutoff tool. Both violations were officially abated by May 2, 2001. The property's only known fire incident involved a contained cooking fire, with no civilian injuries reported. More recent records show a sidewalk cleaning issue documented in January 2024 and a pavement defect complaint from 2016, though these issues were resolved through regular municipal channels and were not directly related to the building's maintenance or safety systems.

Risk rating

How 1257 10Th Ave'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 1493 buildings in this neighborhood, 1015 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
