Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 601-603 Tompkins Ave rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1900
2 or more units

Property type

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1900
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
47thpercentile

Out of 1276 buildings in this neighborhood, 676 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
