Initial analysis

The property at 1310-1314 42nd Avenue is a 2-story multi-family residential building with 4 units, constructed in 1950 and currently owned by the Tam Family Trust. The building has undergone several significant improvements and maintenance work in recent years, with the most recent projects in 2023 involving stucco replacement and painting work on the front and right side of the building, totaling approximately $25,000 between two permits. In 2019, the property underwent substantial interior remodeling work, including the addition of an accessible water closet and various structural improvements, though this work encountered some interruption due to planning department requests and related complaints regarding unpermitted work on plumbing and electrical systems.

The building has had several historical violations and complaints, though most have been resolved. Notable past issues included a 2004 violation regarding a rusted and nonworking fire escape ladder (resolved in 2005) and a 2010 complaint about exterior paint condition and potential lead hazards (resolved in 2010). More recent concerns outside the building structure itself have involved multiple reports of illegal parking and sidewalk blocking in 2022-2025, though these are not directly related to building conditions. The property has also been subject to various street space permits and planning applications, including a significant 2019 project to restore the front facade to its original condition and establish a new restaurant use at the adjacent 4055 Irving Street address. The building appears to be currently in good condition, with no active violations or complaints as of the latest available data.

Risk rating

How 1310-1314 42Nd 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
33th percentile

Out of 632 buildings in this neighborhood, 423 are predicted to be safer.
