Rent & eviction protection

Is 18-20 30Th St 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 1908

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 1908
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 property at 18-20 30th Street in Bernal Heights is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by Mario Macias and Lucy Reyes. The building has experienced several significant events, most notably a major fire in March 2023 that caused structural damage to the east wall and roof, rendering the building unsafe and uninhabitable, with utilities shut off and partial collapse of back stairs. In response to the fire damage, substantial renovation work was initiated in August 2023, including $550,000 worth of repairs to kitchens, bathrooms, and sheetrock in both units. As of early 2025, additional work is planned to replace 20 windows in the building's side and back. The property has ongoing plumbing and electrical upgrades scheduled for March 2024, including the replacement of fixtures throughout both units and a complete rewiring of the building.

The building's history reveals previous concerns about lead paint hazards (2013) and a wooden utility ladder (2009) that were addressed, though there are currently some unresolved issues from 1996 related to an illegal unit and maintenance problems. Recent activity on the property includes a complaint about vacancy filed in November 2024, which remains active. The extensive renovation work following the fire has included multiple permit applications, some of which were withdrawn or revised, indicating ongoing adjustments to the repair scope.

Risk rating

How 18-20 30Th St'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
35thpercentile

Out of 1276 buildings in this neighborhood, 829 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
