Rent & eviction protection

Is 19-21 Liberty 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 before 1979
Built 1900
2 or more units

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

This two-unit residential building, located at 19-21 Liberty Street in Eureka Valley/Dolores Heights, is a 2-story flats and duplex structure built in 1900, currently owned by Salomon Ari & Yamamoto Yori. The building has undergone several significant improvements over the past decade, including a major foundation upgrade in 2016 that replaced unreinforced brick masonry with reinforced concrete at the east wall ($30,000), a comprehensive renovation in 2018 of unit 21 including kitchen and bathroom remodeling, window replacements, and floor refinishing ($20,000). Recent improvements include a completed roof replacement in 2022 ($7,000) and the installation of a solar panel system in the same year (10.27 kW with 26 panels). However, there are currently unresolved construction issues stemming from 2022 involving unauthorized modifications to the rear deck and stair system for unit 21, which led to an active building violation notice. The violation involves several safety concerns, including the adjacent window requiring tempered glazing, improper water heater enclosure, and an unpermitted structural frame wall on the property line, with a director's hearing scheduled for February 2024.

The property has a history of maintenance and improvements, including electrical upgrades such as the transition from overhead to underground service in 2004 (200 amp) and various plumbing modifications. While the building has received numerous permits for repairs and renovations, the ongoing violation regarding the rear deck construction raises significant safety and compliance concerns. The surrounding area has experienced typical urban issues as documented in 311 calls, including tree maintenance needs, encampment reports, and street cleaning matters, though these are more reflective of neighborhood conditions rather than building-specific issues. Recent planning applications submitted for 21 Liberty Street propose rebuilding rear egress stairs to code and creating new spaces in the rear carriage house, indicating ongoing development considerations for the property.

Risk rating

How 19-21 Liberty 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
