Rent & eviction protection

Is 1337 3Rd 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 1912
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 duplex at 1337 3rd Avenue in the Inner Sunset, built in 1912 and owned by Kollins John A III, has experienced several significant maintenance and infrastructure issues in recent years, most notably a series of six sewage backup incidents between February and December 2023, all involving 4-inch sewer vents and requiring PUC Sewer Operations intervention. The most recent plumbing work was a house trap replacement completed in December 2023. The building has a documented history of repairs and upgrades to its essential systems, including additional foundation work in 1992, and multiple renovations in the 1980s, such as kitchen and bathroom remodeling in 1987. While the property has undergone various improvements, including a bathroom remodel in 2000 costing $30,000, there are ongoing concerns with the sewer system that have persisted despite recent plumbing work.

The building's recent history shows relatively minor fire-related incidents, primarily involving smoke detector activations and unintentional alarm triggers, though these events did not result in any civilian injuries. Other maintenance issues have included a collapsed sidewalk (reported in February 2020, currently open) and a vandalized tree (resolved in April 2021). Historical permits from the 1980s indicate significant renovations were undertaken to create new lower units and remodel multiple kitchens and bathrooms.

Risk rating

How 1337 3Rd 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
52ndpercentile

Out of 1493 buildings in this neighborhood, 717 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
