Rent & eviction protection

Is 221-223 9Th 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 1940

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 1940
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 two-unit residential building at 221-223 9th Avenue in San Francisco's Inner Richmond district, built in 1940, has undergone several significant improvements over the past decades, with recent maintenance suggesting active property upkeep by the F & E Shimasaki Family Trust. The most pressing recent issues include a May 2023 complaint about heating and electrical problems, though this complaint is currently listed as not active, and there were multiple sewer-related incidents in January 2024 involving a 4-inch vent issue. The building has seen substantial renovations, including a comprehensive 2020 kitchen and bathroom update ($36,000), a major window replacement project in 2018 ($23,000) that installed 21 new windows, and a $21,000 re-roofing project in 2021. The property has also received important infrastructure improvements, such as the electrical upgrade in 2020 that included a new 50-amp subpanel and four circuits, and plumbing updates including new kitchen fixtures and bathroom components.

Historical records show earlier maintenance work including copper plumbing installation in 1993 (permit expired), a 1990 kitchen remodel, and rear window replacements in 2008. The building has experienced some infrastructure-related challenges recently, with multiple service requests in early 2024 regarding sewer issues, though records indicate these were subsequently resolved. The property has also faced external challenges, as evidenced by a public stairway defect regarding a sunken sidewalk noted in November 2023, though this appears to be an external infrastructure issue rather than a building defect. Despite these occasional issues, the frequency of major improvements and repairs suggests regular maintenance of the property, with recent upgrades focusing on both aesthetics and essential systems.

Risk rating

How 221-223 9Th 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.
