Inner Sunset, SF 94122 1760044 3 units · 3 fl · 1911

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 1326-1328 6Th 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.

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.

Built 1911
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-unit, three-story multi-family residential building at 1326-1328 6th Avenue in the Inner Sunset, owned by Tzu-an & Hui-fang Chen Revo, has undergone several significant maintenance and compliance events since its construction in 1911. In 2003, the property underwent substantial safety improvements, including the replacement of dilapidated rear open stairs and the installation of a 200A electrical termination box. A notable cluster of violations occurred in March 2006, when multiple issues were identified related to fire safety and security, specifically regarding egress obstructions and the lack of self-closing devices on exterior doors; however, these violations were promptly addressed and abated by May 2006.

The building's maintenance history shows attention to structural elements, with a 2002 complaint regarding an unpermitted deck construction being resolved almost immediately, though this incident suggests some prior regulatory noncompliance. A more recent incident from 2013 involved contractors working on the roof without a permit, resulting in damage to neighboring property, though this complaint was subsequently marked as not active. The property has experienced recurring issues with vehicles parking on the sidewalk in the vicinity, with six separate incidents reported between 2018 and 2020, though enforcement officers were unable to locate the offending vehicles in each instance. The most recent concern was reported in August 2023, regarding a lifted sidewalk defect, which was resolved by the Public Works department. The building's permit records show regular maintenance and compliance with safety standards, with no active violations currently on file, suggesting ongoing attention to property upkeep by the owners.

Risk rating

How 1326-1328 6Th 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.
