Rent & eviction protection

Is 223-225 9Th 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.

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 1910
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 three-story multi-family residential building at 223-225 9th Street in San Francisco's South of Market neighborhood, built in 1910, is currently owned by Wang Xiaoning & Guo Yu and contains 6 units. The property has experienced several significant maintenance and safety issues in recent years, most notably an active complaint from May 2023 regarding multiple life safety concerns including unapproved plumbing and electrical work, improper occupancy, lack of permanent heating in an unauthorized unit, and inadequate egress. A 2023 complaint also documented various maintenance problems including non-functional ventilation and drainage issues, while ongoing electrical problems in 2023 affected multiple ground floor outlets. The building suffered a fire in 2022 requiring $40,000 in repairs to two apartment units, and historical records from 2000 show numerous safety violations including issues with stairs, handrails, walls, and smoke detectors, though these were abated by 2016.

The property has undergone various maintenance and improvement work over the years, including significant electrical and plumbing upgrades in 2013 and 2022, bathroom renovations, and compliance work following violations. The ground floor space, which was previously used as a medical cannabis dispensary, has been the subject of multiple complaints regarding unauthorized use and occupancy. Recent plumbing and electrical issues have persisted despite previous repairs, and there have been recurring problems with garbage and debris management around the property, as evidenced by multiple 311 calls in 2024. The building's history includes several false fire alarms and temporary safety concerns, though no civilian injuries have been reported in any incidents.

Risk rating

How 223-225 9Th 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.
