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 2002
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 2-unit residential building at 646 19th Avenue in San Francisco's Central Richmond district is a 3-story structure built in 2002 by the 19th 2014 Family Partnership, following the demolition of a 2-story single-family dwelling on the site in April 2000. The construction project, which had a budget of $370,000, encountered some complications during the demolition phase, with neighboring property owners filing two complaints in late 2001 regarding damage to their walls and foundation, though these complaints were promptly abated within days of being filed. An August 2001 permit revision modified the building's roofline from tile to flat.

The property has experienced various maintenance and service issues over the years, with the most recent significant incident being a sewage backup in April 2023 that was resolved by Public Utilities Commission Sewer Operations. There have been multiple parking-related incidents in the vicinity, including instances of vehicles parking on sidewalks and blocking driveways, with the most recent occurring in November 2024. The building has also faced some exterior maintenance challenges, including a bent permit parking sign in October 2023 and two tree-related issues in 2019 - one involving a fallen tree and another regarding an overgrown tree that required pruning and ivy removal. While these issues have generally been addressed through appropriate city services, they indicate ongoing environmental and maintenance considerations in the building's surroundings.

Risk rating

How 646 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
