Initial analysis

The property at 522-524 3rd Avenue in the Inner Richmond is a two-story multi-family residential building constructed in 1905, currently owned by Brethauer Holdings LLC and containing three units. The building has undergone significant improvements over the past several years, with the most recent major work completed in 2024 including the installation of a new Mitsubishi heat pump and a 240V electrical circuit for roof-mounted AC. In 2023, a 100-amp subpanel upgrade was completed for the second floor. Notable safety upgrades include the installation of a comprehensive NFPA 13R sprinkler system in 2020, complete with monitoring equipment, and the replacement of the entire electrical system in 2015 including a 200-amp service upgrade, whole house rewiring, and removal of old knob & tube wiring.

The property has undergone substantial renovations to improve living conditions and safety features, including the conversion of uninhabitable space into usable living areas in 2019 (adding bedrooms, family room, and bathroom), bathroom conversions in 2018, and various mechanical upgrades including new heating systems and sewer lateral repairs. Historical building violations from 2004 and 2010 related to fire safety, stair repairs, and smoke detector requirements were all resolved by 2005. The building has experienced some water-related issues in 1998, with multiple reports of leaks affecting neighboring properties, though there have been no similar complaints in recent years. Regular safety inspections have been conducted in 2001, 2004, 2010, and 2015, with the most recent 2020 complaint regarding essential construction work being marked as not active. The most recent planning record shows approved modifications including room additions and stair replacements without changing unit counts or sizes.

Risk rating

How 522-524 3Rd 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
97th percentile

Out of 1723 buildings in this neighborhood, 52 are predicted to be safer.
