Hayes Valley, SF 94102 0839034 4 units · 2 fl · 1909

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 231-235 Lily 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 1909
2 or more units

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 1909
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

This two-story, four-unit multi-family residential building located at 231-235 Lily Street in Hayes Valley was constructed in 1909 and has undergone several significant maintenance activities over its lifetime. The most recent major maintenance work includes a completed reroofing project in April 2010 costing $6,500, while an earlier emergency issue was addressed in January 2010 involving standing water in the basement that was quickly resolved within one week. The building has a documented history of stair-related safety concerns, with violations and repairs recorded in both 1995 and 2002, including a notable cluster of issues in February 2002 where multiple violations were identified related to fire safety (including combustible storage, rear stair storage issues, and egress obstructions), security (self-closing devices needed at exterior doors), and stair repairs - all of which were abated by March 20, 2002.

The property has experienced several infrastructure issues over the years, including a sewer leak incident in 1999 that affected adjacent property and recurring concerns with outdoor storage and housekeeping as reflected in multiple 311 calls between 2022-2025 regarding abandoned items and debris. While there have been numerous parking enforcement calls (eight between 2022-2024) related to sidewalk parking and driveway blocking, these are external to the building's operations. The building's maintenance history shows regular upkeep, with three documented reroofing projects: in 1989, 1990, and 2010, along with various other repairs suggesting ongoing maintenance attention by ownership. The property has been subject to routine housing inspections, with the most recent occurring in 2008, though no significant violations have been recorded in the past decade.

Risk rating

How 231-235 Lily 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
