Rent & eviction protection

Is 31 Stillman 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.

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

31 Stillman Street is a two-story multi-family residential building located in the Financial District South, containing 5 units and built in 1914, currently owned by Steve Yen Chen and Cindy Wong. The property has undergone several significant maintenance and repair projects over the past decades, with the most recent work including a completed sewer lateral replacement in July 2024 and previously completed window repairs, deck replacements, and various other maintenance tasks in 2019. The building faced multiple housing code violations in early 2019, including issues with egress obstruction, stair maintenance, and general dilapidation, though these were all abated by August 2019. Historical records show several roofing projects, including a complete reroofing in 2007 costing $10,000, and the property underwent various plumbing and electrical upgrades in 2016, including roof drain installation and electrical system improvements.

The building's recent history (2024-2025) shows ongoing municipal issues in the surrounding area, primarily concerning encampments and garbage/debris management, though these external factors do not directly reflect on the building's condition. Historical fire safety concerns were documented in 2010-2011, including an overcrowding incident and a public assembly violation, but there have been no fire-related incidents or violations recorded in recent years. The property has maintained relatively regular maintenance patterns, with several permits issued for specific repairs and improvements, suggesting ongoing attention to building upkeep despite the challenges noted in 2019.

Risk rating

How 31 Stillman 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.
