Rent & eviction protection

Is 8-10 Henry 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
Built 1901

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 1901
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 8-10 Henry Street in Duboce Triangle is a 3-story, 5-unit multi-family residential building constructed in 1901, currently owned by Maureen Wong Chen Survivors. The building has undergone several significant renovations over the past decade, with the most recent work occurring in 2019-2020, including kitchen and bathroom remodeling, installation of can lights, window repairs, and various electrical upgrades totaling over $100,000 in improvements. However, there were concerning events in October 2019 when multiple complaints were filed regarding unpermitted interior and exterior work, including dust management issues and worker safety concerns during renovation activities.

The building has a history of maintenance and compliance issues, particularly evident in the early 2000s. In 2002, several fire safety violations were documented, including problems with security bars, combustible storage, and stairs, though these were all abated by October 2002. In 2010, there was a complaint about unpermitted window replacement work on the ground floor, and in 2014, tenants reported heating, weatherproofing, and pest control issues. While most of these violations were addressed, the building continues to show signs of wear and requires regular maintenance, as evidenced by multiple renovation projects focusing on kitchens, bathrooms, windows, and electrical systems over the years. Recent 311 calls from 2024 primarily relate to exterior issues such as street cleaning and graffiti, which, while not directly affecting building safety, indicate ongoing maintenance needs in the immediate vicinity of the property.

Risk rating

How 8-10 Henry 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
5thpercentile

Out of 287 buildings in this neighborhood, 273 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
