Initial analysis

This two-unit multi-family residential building, located at 1336-1338 San Bruno Ave in the Inner Mission neighborhood, is a two-story flats and duplex structure built in 1910 and currently owned by Kathleen E & Daniel Bomze. The building's documented history shows several significant improvements, particularly in early 2004 when substantial electrical and structural upgrades were completed, including a kitchen remodel, electrical service changes, and panel installations with an associated cost of approximately $8,000. Earlier improvements from the 1980s and 1990s include the installation of a one-hour exterior elevator shaft for top flat access in 1989 and vinyl siding installation in 1991.

Recent maintenance issues and concerns primarily relate to the building's immediate surroundings, with multiple reports of graffiti (three incidents in 2024 alone) affecting both the building and adjacent public areas. The property faces ongoing infrastructure challenges, with two open cases regarding collapsed sidewalks reported in 2024 and 2022, which may impact resident access and safety. Additional recent concerns include an expired electrical permit from 2004 related to a 200-amp service change with three meters, suggesting incomplete documentation of this significant upgrade. The building has also experienced various public space maintenance issues, including garbage disposal concerns and a faded street cleaning sign, though many of these cases have been resolved through appropriate city agencies.

Risk rating

How 1336-1338 San Bruno 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

Out of 2380 buildings in this neighborhood, 1642 are predicted to be safer.
