Rent & eviction protection

Is 1379-1381 31St 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.

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 1945
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 two-unit multi-family residential building, located at 1379-1381 31st Avenue in the Central Sunset neighborhood, is a two-story flats and duplex structure built in 1945. The property, currently owned by Norman M. Ng and Cherie X. Liu, has undergone several notable improvements and maintenance works over the past 14 years. Most recently, in 2012, an entrance remodeling project was completed at the first floor entry, which included the installation of a new French door and the renewal of entry tile flooring, with the work valued at $5,000. Prior to this, in 2011, the building required termite remediation work as documented in Permit #201105065551, associated with Termite Report #11120, affecting items 4, 8, and 6, with an estimated cost of $5,000. Of particular significance to resident comfort and infrastructure, the property underwent necessary plumbing improvements in 2009, with the replacement of the sewer line from the front of the garage to the city curb, a critical maintenance task completed under Permit #PP20090127709. While the building has seen regular maintenance and improvements, there are no recorded instances of major structural modifications or safety violations in the available permit history.

Risk rating

How 1379-1381 31St 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
68thpercentile

Out of 814 buildings in this neighborhood, 260 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
