Rent & eviction protection

Is 1452 17Th 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 1947
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.

Built 1947
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 4-unit, 2-story multi-family residential building at 1452 17th Avenue in the Inner Sunset, owned by the Chew Family Living Trust, has been standing since 1947. The most significant structural work on record was conducted in 1996, when underpinning work was performed on the northside foundation due to an adjacent new building development, though this permit has since expired. The building has undergone three routine Housing Inspection Services inspections (2001, 2011, and 2014) with the most recent complaint filed in 2014 regarding an old and corroded oven, though this issue does not appear to have been formally resolved in the records.

In recent years, the property has experienced recurring issues with sidewalk parking, particularly between 2018 and 2022, with multiple citations issued to the same vehicle (which appears to have a pattern of parking violations based on license plate information). There was also one instance of loose garbage requiring cleaning in 2020. While these maintenance and parking enforcement issues do not directly indicate building safety concerns, they suggest ongoing challenges with property management and maintenance of common areas. The building's documented history shows regular inspections occurring approximately every decade, with only one complaint regarding interior appliances in recent years, though the limited number of complaints could also indicate either effective management or underreporting of issues. The available records highlight both structural modifications made nearly three decades ago and regular scrutiny of the building's common areas through routine inspections.

Risk rating

How 1452 17Th 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
38thpercentile

Out of 1493 buildings in this neighborhood, 926 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Director's hearing rate, owner's portfolio

Per-building rate of director's hearings across the owner's portfolio.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
