Initial analysis

The property at 601-603 35th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1946 and currently owned by Edmund M. Wu, this flats/duplex style building has undergone several significant renovations over the years, with the most substantial work occurring in 2018. During this period, major improvements included the construction of two new family rooms with half bathrooms on the ground floor, a second-floor kitchen remodel, bathroom additions, and various infrastructure upgrades such as new piping, furnace relocations, and electrical work including the installation of smoke detectors and appliance connections. In 2007, the building received attention for structural maintenance, including repairs to dry rot in the cantilever bays on both the west and south sides, along with a replacement exterior staircase, while earlier renovations in 2005 focused on kitchen and bathroom updates.

More recently, there was one documented safety incident related to a carbon monoxide detector activation (with no actual CO detected), which resulted in no civilian injuries. The property has generated numerous parking-related complaints in 2024, with multiple citations issued for blocking driveways and illegal parking on sidewalks, though many of these were marked as "Unable to Locate" or "Other illegal parking." The most recent modification was a garbage-related complaint in January 2025. The building's maintenance history suggests regular upkeep, with particular attention paid to water-related issues as evidenced by multiple dry rot repairs over the years, including a notable instance in 1995 when work was required on overhangs and balcony/stucco areas. All permitted construction and repair work appears to have been properly documented and completed, with no outstanding permits or violations on record.

Risk rating

How 601-603 35Th 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.
