Rent & eviction protection

Is 4364 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 1964
2 or more units

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 1964
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 4364 17th Street in Corona Heights, owned by Martha Wong, is a two-story structure built in 1964. The property has undergone several significant improvements over the past three decades, including a complete reroofing in 2010 ($4,400), window replacement in 2006 ($13,800), and more recent infrastructure work in 2017 involving retaining wall replacement ($50,844) and deck repairs ($5,800). Most notably, the building's plumbing infrastructure was recently updated in July 2024 with the replacement of the sewer lateral and house P trap. The property has experienced some maintenance issues that have impacted the surrounding area, including a currently open sidewalk defect reported in April 2024 regarding collapsed sidewalk conditions, and a previously blocked sidewalk in February 2024 caused by privately maintained vegetation.

The building's recent history shows attention to both property maintenance and neighborhood concerns, with several resolved cases related to parking and sidewalk issues in 2022-2024. Two parking enforcement actions were taken in August 2022 against a vehicle blocking the driveway, and a citation was issued for illegal sidewalk parking in March 2022. Other neighborhood maintenance issues have included graffiti removal in September 2023 and a loose garbage incident in October 2023, both of which were resolved. Infrastructure improvements, including the 2024 plumbing work and previous retaining wall and deck repairs, suggest ongoing attention to the building's structural maintenance needs, though the recent sewer vent cover issue in late 2021 indicates occasional maintenance oversights.

Risk rating

How 4364 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
85thpercentile

Out of 348 buildings in this neighborhood, 52 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
