Rent & eviction protection

Is 4528-4530 19Th 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.

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 1923
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 three-unit, three-story multi-family residential building at 4528-4530 19th Street in the Eureka Valley/Dolores Heights neighborhood, owned by John D Moriarty 2012 Revoca Trust, has experienced several significant maintenance and safety issues since its construction in 1923. Most notably, in 2021, there were multiple active violations related to fire safety and building maintenance, including the need for fire extinguishers, carbon monoxide and smoke alarm compliance, bathroom ventilation, and wall repairs. The building underwent some remediation in 2021 with the installation of a bathroom fan to address ventilation issues. A serious sequence of complaints in early 2021 reported heating problems and mold, particularly concerning a bathroom ceiling held up with duct tape, though this particular complaint was marked as not active by June 2021.

The building's maintenance history shows some attention to structural integrity, with foundation work documented through permits in 1990, though these permits have since expired. Recent building activity includes a tenant buyout at the neighboring address (4522 19th Street) in July 2024, though this occurred at a different property address than the main building in question. The property has generated multiple 311 calls in recent years, including reports of flooding on the street (January 2024) and various municipal service requests. While there was one recorded fire-related incident involving an unintentional alarm transmission, there were no civilian injuries reported. The building has undergone routine housing inspections over the years, with the most recent significant inspections occurring in 2017 and 2021.

Risk rating

How 4528-4530 19Th 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
10thpercentile

Out of 1278 buildings in this neighborhood, 1150 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
