Rent & eviction protection

Is 4801 17Th 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 1951

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 1951
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 three-story, five-unit apartment building located at 4801 17th Street in the Parnassus/Ashbury Heights neighborhood was built in 1951 and is currently owned by the Seiki Family 1992 Revocable Trust. The property has undergone several significant improvements, most notably completing a mandatory soft-story seismic retrofit in 2022 at a cost of $47,000, bringing it into compliance with San Francisco building codes. The building has experienced recurring maintenance issues, particularly in 2006 when multiple violations were documented including problems with stairs, water heaters, and the central alarm system, though some of these issues appear to have been addressed through various permits, including stair repairs and water damage remediation.

Recent activity around the property has included multiple service requests through 311 calls in 2024, primarily dealing with street and sidewalk maintenance, parking violations, and graffiti removal. The building has had several fire department responses, though none involved civilian injuries, with incidents primarily related to malfunctioning detectors and contained cooking fires. The property has also undergone routine housing inspections in 2009 and additional fire safety inspections in 2023, with a notable inspection in February 2021 regarding compliance with the Tier III soft-story retrofit requirements. While the building's seismic retrofitting has been completed, the property has experienced periodic issues with exterior maintenance and safety systems, as evidenced by the numerous 311 calls and historical violations.

Risk rating

How 4801 17Th 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
13thpercentile

Out of 526 buildings in this neighborhood, 458 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
