Rent & eviction protection

Is 1917-1921 Jackson 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 1939

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 1917-1921 Jackson Street in Pacific Heights, owned by Rosalia S Castleton Revoc T, has undergone significant changes and faced various issues since its construction in 1939. The building has seen several major improvements, including window replacements in 2010 (a project costing over $10,500 that involved replacing 27 windows), an electrical service upgrade recently issued in September 2023, and structural modifications in 2001 that added a wall and room. However, some concerning issues have arisen, particularly in 2017 when multiple housing code violations were documented, including problems with floor coverings, security, plumbing fixtures, and interior surfaces, all of which were resolved by October 2017. A particularly alarming complaint from August 2017 detailed several maintenance concerns: unsafe flooring on stairs, unstable appliances, deck deterioration, electrical issues, window problems, and potential lead paint concerns, though these issues were marked as abated.

The property has recently experienced some infrastructure challenges, including flooding in January 2024 and concerns about tree roots damaging sidewalks (reported December 2023). There have been multiple parking enforcement calls regarding driveway blocking between 2022 and 2025, and some recent service requests related to illegal postings and tree maintenance in early 2023. Historical records show some past concerns about unauthorized construction in 2005, though this was addressed and related to work that was eventually legalized. The building's maintenance history shows a pattern of addressing both regular upkeep and more substantial improvements over the years, with the most recent major work being the 2023 electrical upgrade. Two fire incidents were recorded near the address, though neither involved civilian injuries, and no tenant buyouts have been recorded for this particular address.

Risk rating

How 1917-1921 Jackson 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.
