Initial analysis

The two-unit residential building at 601-603 Tompkins Avenue in Bernal Heights, owned by Richard J. Modolo, is a two-story flats and duplex structure built in 1900. The property has undergone several significant renovations and improvements over the years, most notably in recent years with the replacement of aluminum windows with wood-clad windows on the second floor in 2017 ($8,965), and a substantial exterior improvement project in 2015 ($25,000) that included the addition of an outdoor kitchen enclosure, new concrete stairs, and other enhancements. Utility upgrades were completed in 2016 with the installation of new gas and water lines, though some associated electrical work related to exterior lighting and receptacles has an expired permit status.

Of critical concern are recent fire safety issues, with multiple fire code violations cited in October 2024, including problems with sprinklers, electrical systems, and emergency lighting; similar violations were also noted in November 2023. The building has a history of fire safety concerns, with documented violations dating back to 2019, and mechanical system problems have also been documented, including a sewage backup incident in July 2024. The property has experienced various maintenance and environmental service issues in the past year, including multiple reports of garbage overflow and debris, though these are generally addressed by city services. While the building has undergone some significant improvements, the recurring fire code violations and safety issues warrant attention, particularly given their recent frequency and the range of systems affected.

Risk rating

How 601-603 Tompkins 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
47th percentile

Out of 1276 buildings in this neighborhood, 676 are predicted to be safer.
