Initial analysis

The two-unit multi-family residential building at 1201 40th Avenue in the Outer Sunset, owned by Braganza Michael & Shen Lim, was constructed in 1946 and consists of two stories. The building's maintenance history shows regular upkeep, with significant work including reroofing projects in 1988 ($7,300) and 2010, and minor dry rot repairs to the front facade in 2003. The electrical system received an upgrade in 2016 with the installation of a new meter, grounding, and bonding system.

Recent events (as of January 2025) show multiple infrastructure and maintenance issues in the vicinity of the building, though none directly related to the property itself. These include reports of garbage and debris, a burnt-out streetlight, and several instances of graffiti in December 2024 that were subsequently resolved. The most recent tenant buyout related to this property occurred in March 2021, involving 2 tenants and a payment of $13,000, though this appears to be associated with an adjacent address (3909 Lincoln Way). The building's documented history shows regular maintenance and responsiveness to infrastructure needs, though the recent spate of 311 calls suggests increased attention to neighborhood maintenance requirements in the surrounding area.

Risk rating

How 1201 40Th Ave'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
