Rent & eviction protection

Is 1200 21St 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 1926

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 1926
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, two-story residential building at 1200 21st Avenue in the Central Sunset neighborhood, owned by Joe Che Yee, was constructed in 1926 and is classified as a Flats & Duplex building. The property's historical permit records show minimal activity, with only two cancelled building permits from 1981 and one expired electrical permit from 2005 related to a 200-amp underground conversion.

Recent conditions around the property from 2024-2025 indicate persistent challenges with street maintenance and public cleanliness. There have been multiple reports of garbage and debris on the street, including three instances of human waste or urine between December 2024 and January 2025, as well as other types of loose garbage and yard waste. The area has faced recurring issues with encampments, particularly in September 2024, when park rangers responded to relocate unhoused individuals and excessive debris. Structural maintenance concerns were noted in multiple reports, including graffiti in December 2024 and issues with recreation equipment in August 2024. The frequency of these incidents suggests ongoing challenges with the immediate vicinity, though it's important to note that most reported issues were addressed and resolved by city agencies.

Risk rating

How 1200 21St 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
44thpercentile

Out of 814 buildings in this neighborhood, 456 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
