Rent & eviction protection

Is 631-633 15Th 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 1921

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.

15+ years since occupancy
Built 1921
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 2-unit multi-family residential building at 631-633 15th Avenue in the Central Richmond neighborhood, owned by Mina Choo and Minsik Pak, was constructed in 1921 and is classified as a Flats & Duplex building with two stories. The property underwent significant renovations in 2013-2014, with major work including comprehensive updates to both units' kitchens and bathrooms, creation of a recreation room in the garage, installation of new interior stairs, and structural modifications to improve garage access, all completed at a cost of $210,000. Additional improvements during this period included new plumbing systems for both units, electrical upgrades including a complete rewiring, installation of new water heaters, and bathroom renovations, supported by the replacement of six street-facing windows with wood windows.

More recently, the building has seen sustainable upgrades with the installation of solar power systems in 2022, including two separate rooftop solar installations (2.8 kW and 3.8 kW) with Tesla Powerwall energy storage systems. Historical records show the building underwent reroofing work in 2003, though this permit is marked as expired. The property has experienced minimal issues over the years, with the most significant being a sewage backup incident in 2012, and occasional parking-related concerns in the vicinity. The building was legally converted to two condominiums under the DPW Lottery Bypass program, with the conversion approved by planning authorities. Recent 311 calls have primarily related to street cleaning and parking matters rather than building-specific issues, suggesting good maintenance and management of the property.

Risk rating

How 631-633 15Th 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
78thpercentile

Out of 2250 buildings in this neighborhood, 495 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
