Rent & eviction protection

Is 606 36Th 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.

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 606 36th Avenue in San Francisco's Outer Richmond district, owned by Tony M Gao and Le Thuy Diem, has a documented history spanning several decades since its construction in 1926. Significant building modifications include a notable incident in 2010 involving unauthorized construction of a rear addition (approximately 16ft x 10ft), which triggered a complaint and subsequent violation notice under SFBC Section 103A; this unauthorized work, which included new stairs constructed approximately 10 feet above grade, was later documented as properly completed through permit number 201009271640 with a valuation of $10,000. Earlier improvements included termite damage repairs in 1987 (permit expired) and a 1985 renovation of part of the garage area into a 16' x 20' playroom.

The property has experienced recurring issues with parking violations and sidewalk maintenance in recent months. Between September and November 2024, there were multiple reports (at least seven) of driveway blocking incidents requiring parking enforcement citations. Additionally, there were complaints regarding garbage and debris, including a mattress incident and a sidewalk defect involving collapse, though most of these cases have been resolved. A tree maintenance issue related to backfilling a tree basin remains open as of September 2024. While the building's major structural modifications appear to have been resolved through proper permitting processes, the recent spate of parking violations and sidewalk-related issues may impact resident experience in the immediate vicinity.

Risk rating

How 606 36Th 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
52ndpercentile

Out of 1040 buildings in this neighborhood, 499 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
