Rent & eviction protection

Is 4943-4949 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.

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 property at 4943-4949 17th Street, owned by Peter Chin and Susan Lai, is a two-story, four-unit multi-family residential building constructed in 1947 in the Parnassus/Ashbury Heights neighborhood. Over the years, the building has undergone several significant maintenance and improvement projects, including the installation of new decking at the rear of the building for both floors in 2006 (cost: $10,000) to comply with a notice of violation. In 2008, repairs were made to address dry rot at the front of the building (cost: $6,000) and electrical work was completed to install a workshop fan, laundry facilities, and associated electrical components.

The building has a history of routine housing inspections, with the most recent occurring in October 2016. A cluster of violations was recorded in April 2006, including issues with fire extinguishers, stairs, water heaters, and gas meter instructions, all of which were subsequently addressed. The property experienced some safety-related incidents in 2000, including concerns about chord wiring, fire extinguisher maintenance, and a BBQ grille issue, though these were all abated by September 2000. More recently, in 2022, there were two infrastructure-related concerns reported via 311 calls: a lifted sidewalk and an off manhole cover, both of which were resolved.

Risk rating

How 4943-4949 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
33rdpercentile

Out of 526 buildings in this neighborhood, 352 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
