Rent & eviction protection

Is 825 25Th 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 1930
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.

15+ years since occupancy
Built 1930
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 825 25th Avenue is a two-unit, two-story multi-family residential building located in the Central Richmond neighborhood, owned by David & Fu-ling Sun 2010 Tr and constructed in 1930. The building has experienced several maintenance and infrastructure issues in recent years, with the most significant being a sewage backup incident in December 2023 and a water main repair in March 2021. There was an attempt in 2017 to modernize the bathroom facilities with comprehensive improvements including plumbing and electrical work, but these permits were ultimately cancelled. Earlier maintenance records show a back stair repair and kitchen cabinet work permitted in 1988, though this permit expired.

The property has generated multiple service calls to city agencies over the past few years, including three instances of driveway blocking in 2020 and 2024, and various street-related issues such as a pavement defect in December 2023. Other notable incidents include tree damage in 2021, missing sign repair in 2021, and an unsuccessful service request in February 2022. While many of these issues have been resolved through appropriate city departments, the frequency of recent plumbing-related problems, particularly the 2023 sewage backup, may be of concern regarding the building's infrastructure.

Risk rating

How 825 25Th 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
71stpercentile

Out of 2250 buildings in this neighborhood, 652 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
