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 1988
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
May be covered by AB 1482. The building is old enough for the statewide rent cap (5% + regional CPI, capped at 10% per year) and just-cause protection after 12 months of tenancy.

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 property at 770-772 35th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1988, currently owned by Lee Kwok Pong & Wai Fong. The building's permit history shows an interesting transition from a single-family dwelling to its current duplex form, with permits documenting the demolition of a former structure in October 1986, followed by two permits related to bar sink installations, one of which was cancelled but the other (completed in 1988) involved terminating a bar sink in the basement.

The building has experienced notable plumbing and sewage issues in recent years, with four separate sewer-related incidents reported between December 2022 and April 2023, including flooding, sewage backup, and odor problems from the sewer vent. While these issues were resolved through Field Work, they represent the most significant pattern of maintenance concerns on record. The only fire safety incident recorded was a carbon monoxide detector activation with no actual CO detected, and there have been no recorded civilian injuries. More recent incidents have primarily involved parking enforcement matters and street cleaning issues, including several reports of vehicles blocking driveways and one case of double parking in 2021. The most recent activity at the address involves a vehicle-related complaint from January 2024.

Risk rating

How 770-772 35Th 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
81stpercentile

Out of 1040 buildings in this neighborhood, 198 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
