Rent & eviction protection

Is 156 Duboce 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 1924

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

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 8-unit, 2-story apartment building at 156 Duboce Avenue, built in 1924, has undergone significant seismic improvements as part of San Francisco's mandatory soft-story retrofit program. The building, owned by Chang Sing & Chin Bee Cho T, successfully completed its soft-story retrofit in 2022, including a comprehensive fire system upgrade with new panel, smoke detectors, and low-frequency horns installed throughout all units. The property has experienced several maintenance and compliance challenges over the years, with notable issues including a serious staircase safety concern in 2021-2022 when a section of stairs was replaced without proper permits, leading to code violations that were eventually resolved through proper repairs and permits in early 2022.

Historical records show a pattern of building maintenance improvements and occasional compliance issues, including a significant window replacement project in 2010, garage foundation and mezzanine work in 2002, and various repairs and upgrades over the years. The building has faced several tenant-related complaints regarding unauthorized work, including a 2019 complaint about unpermitted kitchen and bathroom renovations in Unit #1, and concerns about lead paint management during 2013 exterior painting work. More recent issues have included complaints about excessive noise during construction work in 2022 and concerns about sewage problems in 2014, though these were eventually resolved. The property has maintained active compliance with recent building safety requirements, evidenced by the issuance of the Certificate of Final Completion for the soft-story retrofit work.

Risk rating

How 156 Duboce 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
4thpercentile

Out of 799 buildings in this neighborhood, 767 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
