Rent & eviction protection

Is 1938-1940 19Th 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 before 1979
Built 1945
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 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

Located in San Francisco's Inner Parkside neighborhood, this 2-unit duplex was built in 1945 and is currently owned by Mike Wen Hu Yao and Lin Yingx. The two-story multi-family residential building has a notable history of permit activity and compliance issues. Most significantly, in March 2008, the building received a violation for constructing an illegal third unit in the garage level, along with unauthorized stucco work at the front garage area. These issues were addressed through a completed permit in 2008 that required the illegal kitchen removal and garage stucco repairs, with the violation ultimately being abated in March 2010.

The building has undergone several permitted improvements over the years, including a substantial renovation in 2002 that added a storage room, study room, and bathroom to the ground floor, along with associated electrical work. The second floor received kitchen remodeling in 2008, which was properly permitted and included electrical upgrades. Prior maintenance work included a roofing project from 2000 and vinyl siding installation in 1989, though these permits eventually expired. A recent street space permit was issued in September 2013, but no significant violations or complaints have been recorded in the past decade, suggesting a period of relative compliance. The building's permit history demonstrates a pattern of addressing unauthorized modifications through proper channels, most notably the 2008 violations that were ultimately resolved through permitted repairs and remediations.

Risk rating

How 1938-1940 19Th 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
76thpercentile

Out of 121 buildings in this neighborhood, 29 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
