Rent & eviction protection

Is 3339-3341 Judah 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 1934
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.

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 3339-3341 Judah Street is a one-story, two-unit multi-family residential building located in San Francisco's Outer Sunset neighborhood. Built in 1934 and currently owned by the Chau Family Trust, this flats/duplex structure has undergone several significant modifications and faced some challenges over its history. The most substantial incident occurred in 1987 when fire damage prompted a repair permit, followed by roof modifications to a storage shed later that same year. In the early 1990s, the building underwent bathroom and utilities room renovations, though a related abatement order from 1994 was ultimately cancelled. Window upgrades were completed in 1983 with the installation of three aluminum windows.

The property has experienced various infrastructure and maintenance issues in recent years, particularly between 2021 and 2023. There were multiple incidents of vehicles blocking driveways in 2022 and 2023, resulting in at least three citations being issued. Street maintenance issues have been documented, including hazardous materials clean-up and loose garbage removal in 2023, as well as two pavement defect reports in late 2021 which were either resolved or transferred for further action. The most recent incidents involved general street cleaning and an abandoned vehicle complaint, both in December 2023, though these were determined to have minimal impact on the property itself. While the building's major structural work appears to have been completed in earlier decades, recent maintenance issues have primarily involved external factors rather than the building's internal systems.

Risk rating

How 3339-3341 Judah 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
34thpercentile

Out of 632 buildings in this neighborhood, 417 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
