Inner Mission, SF 94110 3576043 4 units · 2 fl · 1910

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 9-11 Lexington 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 1910
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 4-unit, 2-story multi-family residential building at 9-11 Lexington Street, located in the Inner Mission neighborhood, has undergone several notable maintenance and improvement projects since its construction in 1910. Most recently, a reroofing project valued at $12,500 was permitted in October 2024, involving the installation of a new three-layer built-up roof system. The building's maintenance history includes various significant repairs and upgrades, such as kitchen renovations in Unit 1 (2014), siding replacement on a blind wall (2008), and the repair of dry rot on the deck and front door in 1999. The property has undergone routine housing inspections in 1999 and 2008, both of which were resolved without any active concerns.

In terms of recent cleanliness and maintenance issues, there have been multiple reports of garbage and debris on or near the property throughout 2023 and 2024, with six documented cases between May and October 2024, all of which were resolved. These incidents indicate an ongoing challenge with waste management in the vicinity. Additionally, there was one report of graffiti in June 2023 and an illegal parking complaint in September 2023, both of which were addressed by appropriate authorities. The building's ownership is registered to Kien Va Nguyen and Bien Thi Tra, and while the property has maintained compliance with housing inspections, the frequency of recent cleaning-related complaints suggests some challenges with ongoing property maintenance.

Risk rating

How 9-11 Lexington 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
55thpercentile

Out of 2380 buildings in this neighborhood, 1071 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
