Rent & eviction protection

Is 1391 37Th 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 1945

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 1945
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 two-unit residential building at 1391 37th Avenue in the Outer Sunset district, owned by the Chan Family Trust, has a documented history spanning several decades since its construction in 1945. Significant unauthorized construction activity was reported in 2021, with complaints about nighttime work occurring without proper permits. In 2010, there were multiple housing code violations related to interior conditions, including issues with lead-based paint, damaged ceilings and walls, mold/mildew, plumbing problems, and window repairs, all of which were abated by October 2010. The building underwent two notable permitted improvements: a ground floor bedroom and family room addition in 2010, and the construction of a storage room and bathroom in the basement in 1994.

The property has experienced recurring concerns about potential unauthorized dwelling units, with investigations in 2010 and 2012 regarding possible illegal basement and garage units. Historical complaints from 1994 also indicated issues with hot water availability. More recently, in late 2024, there have been multiple reports (over ten in December alone) regarding overflowing city garbage cans and debris on the street, though these are external sanitation issues and not directly related to the building's condition. While the major historical violations have been resolved, the building's record shows a pattern of unauthorized modifications and maintenance issues that required regulatory intervention, particularly in the early 2010s.

Risk rating

How 1391 37Th 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
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.
