Rent & eviction protection

Is 1400 34Th 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 1946
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 1946
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 multi-family residential building at 1400 34th Avenue in the Central Sunset neighborhood, owned by Kwan Jun and Git Jun Young, has experienced several maintenance and cleanliness issues over recent years. Since 2021, there have been multiple incidents requiring street and sidewalk cleaning, including three instances of abandoned garbage and debris (most recently in July 2024), as well as the removal of electronic waste and furniture in October and September 2024, respectively. The property has also been impacted by several sanitation issues, including a case of human or animal waste in August 2023 that required PUC Sewer Operations intervention.

More recent concerns include an open graffiti case from January 2025 and a rent board inquiry from the same month, both of which remain unresolved as of now. The building's exterior and surrounding area have faced various challenges, including a bent stop sign that was reported and subsequently resolved in August 2024. Historical records show the property has been subject to similar issues in previous years, with documented cases of graffiti (both offensive and non-offensive) in 2022, and general cleaning needs in 2021-2022, all of which were eventually resolved. While the majority of these incidents have been addressed through city services, the recurrence of cleanliness and maintenance issues suggests an ongoing challenge in maintaining the immediate environment.

Risk rating

How 1400 34Th 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
36thpercentile

Out of 814 buildings in this neighborhood, 521 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
