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 4150 Lawton 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 1958

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 1958
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 4150 Lawton Street property is a two-story, four-unit multi-family residential building located in the Outer Sunset neighborhood, constructed in 1958 and currently owned by Edward S. Fang. The building has undergone several significant improvements over the years, with the most recent substantial work being street space permits issued in late 2018, and a completed reroofing project in 2016 costing $15,000. In 2002-2003, three of the four apartments underwent kitchen and bathroom renovations, totaling over $20,000 in improvements, and in 2000, the building received important updates including window replacement with double-glazed vinyl frames and a previous reroofing project. Historical complaints suggest minor maintenance issues in the late 1990s, including concerns about windows, flooring, and shower doors, though these were resolved promptly.

The building's recent history shows no filed complaints regarding structural or maintenance issues since 2003, indicating generally stable conditions. The most significant recent activity has been related to street maintenance, with multiple 311 calls between October and December 2024 concerning street cleaning and debris removal, though these appear to be external to the building itself and relate to public spaces. A street space permit was issued in 2018, though its specific purpose is not detailed in the available records. The only recorded fire-related incident was an extrication from a vehicle, which occurred near but not directly related to the building. No recent housing inspections or complaints about building conditions have been filed, suggesting either improved management or reduced issues, though this should be interpreted with caution as not all issues may be formally reported.

Risk rating

How 4150 Lawton 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
14thpercentile

Out of 632 buildings in this neighborhood, 544 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
