Initial analysis

The 4-unit, 2-story multi-family residential building at 4145-4151 Lawton Street in San Francisco's Outer Sunset neighborhood was constructed in 1954 and is currently owned by the Kan Bing Tim&Doris S Revocable Trust. The building's maintenance records show minimal major work, with only one reroofing permit on file from 1998, which has since expired. The property's building inspection history includes two routine common area inspections conducted by Housing Inspection Services in 2001 and 2011, both of which were completed and closed without any noted ongoing issues.

Recent activity around the property, while not directly related to building conditions, suggests regular urban challenges typical of the neighborhood. Between 2019 and 2024, there have been multiple documented incidents of street cleaning needs, including reports of loose garbage (most recently in July 2024), abandoned vehicles (including one tow in January 2020), and parking enforcement matters such as blocked driveways. A more serious incident occurred in 2019 involving offensive graffiti on the building, though this was promptly addressed and resolved the following day. The building's only fire-related incident on record was a minor outside rubbish fire with no civilian injuries, though no date is specified. Overall, the building's official records indicate basic compliance with routine inspections and minimal major maintenance history, with most reported issues relating to street conditions rather than building safety or habitability.

Risk rating

How 4145-4151 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
