Initial analysis

This two-story, four-unit multi-family residential building located at 1542 48th Avenue in San Francisco's Outer Sunset neighborhood was built in 1975 and is currently owned by Peter Bee Lim Lee & Yim Chi. The property has undergone regular maintenance, with three documented reroofing projects, the most recent completed in October 2022 at a cost of $21,500. Prior maintenance work includes bathroom and kitchen fixture replacements completed in 2010.

The building experienced several significant issues in March 2002, when a routine housing inspection revealed multiple safety concerns, including the need for battery-operated smoke detectors, a broken window pane, and serious fire hazards related to combustible storage in the garage area, particularly involving cardboard boxes stored near vehicles. These violations were all addressed and abated by April 2002. More recently, there have been ongoing sewer system issues, with two reported sewage back-up incidents in October and November 2024, both originating from a side sewer vent. The property has also experienced frequent parking enforcement issues in 2024, with multiple citations issued for driveway blocking and parking violations, as evidenced by ten separate parking-related incidents between May and December 2024.

Risk rating

How 1542 48Th 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.
