Rent & eviction protection

Is 1419-1421 19Th 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 1946

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.

Built 1946
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 1419-1421 19th Avenue in San Francisco's Central Sunset neighborhood, owned by the Kent & Minling Ruan Trust, is a two-story flats/duplex structure constructed in 1946. The building's documented history shows several maintenance and improvement projects from the 1980s, including a horizontal rear addition, front stucco work, and installation of aluminum windows, all properly completed. More recently, in 2015, minor sidewalk repairs were performed. A fire complaint was filed in December 2016 for operating without a permit, but this issue was promptly resolved within three weeks.

The immediate vicinity of the property has experienced various street-level issues in recent years, particularly during 2023-2024, with multiple reports of graffiti affecting public transit infrastructure and city receptacles, though these were not directly related to the building itself. Other external incidents included medical waste (needles) removal, garbage and debris issues, and a pavement defect, all of which were resolved by city services. The neighborhood's ongoing maintenance needs have been consistently addressed by city departments, with all reported cases being closed and resolved, though some required multiple reports to achieve resolution. The building's permit and complaint history suggests regular maintenance has been performed when required, with no significant structural or safety issues reported since the 1980s renovations and 2016 permit violation.

Risk rating

How 1419-1421 19Th 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
37thpercentile

Out of 814 buildings in this neighborhood, 513 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
