Rent & eviction protection

Is 1857-1859 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.

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.

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 1857-1859 19th Avenue in San Francisco's Central Sunset neighborhood is a 2-story flats and duplex structure built in 1948, currently owned by Lew Walter & Oy Yee L Revoc. The building's maintenance record shows two significant permitted improvements: a complete reroofing project undertaken in 2009 at a cost of $4,000, and a completed horizontal extension in 1987, though specific details regarding the nature and scope of this expansion are not provided in the records.

In terms of recent incidents affecting the property and its accessibility, there has been a notable pattern of parking enforcement issues, particularly related to blocked driveways. From 2020 through September 2023, there have been 11 documented cases of vehicles blocking driveways, with citations issued in most instances, suggesting ongoing challenges with street parking enforcement in the area. However, the most recent building-related incident dates back to May 2020 when there was an issue with loose garbage requiring attention from the Department of Public Works, which has since been resolved. The consistency of parking enforcement actions suggests this may be an ongoing concern for residents in the area during that period, though these incidents are not directly related to the building's structural or operational condition.

Risk rating

How 1857-1859 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
84thpercentile

Out of 814 buildings in this neighborhood, 130 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
