Rent & eviction protection

Is 85 Corwin St 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

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 1966
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 85 Corwin Street is a 2-story, 3-unit multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, built in 1966 and currently owned by Victor Tsang. The building has undergone several significant maintenance and improvement projects, most notably in 2015 when a $20,000 reroofing project and $500 siding board replacement were completed, along with window replacements worth $6,000. A drainage improvement was made in 2007 with the installation of a 74-foot-long French drain and catch basin. The building has experienced recurring fire safety issues over the past 17 years, with the most recent violations occurring between February and December 2023 regarding alarm systems and sleeping area requirements. Previous fire safety concerns included problems with blocked exits, combustible materials, and fire extinguisher maintenance, though these violations were typically corrected promptly.

More recent building complaints include issues with bright motion sensor lights in 2022, which were resolved within a week. The property has been the subject of various municipal services calls in the surrounding area, including multiple parking enforcement actions (notably in 2019 and 2024), street cleaning matters, and a sewer-related incident in 2019 which was determined to be groundwater rather than sewage. Recent fire violations from 2023 include issues with the sprinkler system and 5-year service requirements, while earlier violations from 2020 involved multiple fire code infractions including problems with alarms, exits, and extinguishers, all of which were subsequently corrected.

Risk rating

How 85 Corwin St'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
