AI summary

The property at 3146-3148 Broderick St is a two-story, three-unit multi-family residential building located in San Francisco's Marina neighborhood, built in 1925 and currently owned by Wong/chui Revoc Trust. The building has undergone several significant maintenance and repair updates over the years, including a complete reroofing in 2015 (cost: $9,300), plumbing work in 2016 involving replacement of an 8-foot section of pipe from the street trap to the main house, and structural improvements in 2004 when rotted exterior stair treads, deck boards, and guardrails were replaced (cost: $4,500). The building has experienced some maintenance issues, with three separate shower-related complaints filed in 2005, including one about an inoperable shower that had been non-functional for about one month despite landlord promises for repairs.

The property underwent a routine housing inspection in 2003 that revealed multiple safety concerns, including issues with fire safety equipment (such as fire extinguishers and a fire escape drop ladder), smoke detector placement, and gas utility shutoff tools. These violations were all abated by March 26, 2003. A subsequent routine inspection in 2006 noted the need for directional signs, which was also resolved. The building's system infrastructure appears to have received regular attention, with multiple completed permits for roofing and plumbing work. While the property has had several residential complaints over the years, including a 2001 complaint about lack of hot water, most recent issues have been limited to exterior maintenance matters such as driveway blocking incidents, waste management, and occasional sidewalk cleaning needs as documented in 311 calls from 2022-2025. The most recent documented issue was a weed and grass complaint from August 2016, though this was marked as "No Access To Building" upon investigation.

Risk rating

How 3146-3148 Broderick 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.
