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 2004
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

Located in the Central Richmond neighborhood, 638-640 24th Avenue is a three-story, two-unit multi-family residential building constructed in 2004, replacing a previously existing single-family dwelling. The building's construction followed proper procedures with the demolition of the old structure being permitted, and both electrical permits for installation of new meters, plugs, lights, and a garage door operator were completed successfully in 2003-2004 with a combined cost exceeding $380,000 for the new structure.

The property has experienced several maintenance issues over its lifetime, most notably a significant balcony repair in 2011 on the third floor due to rainwater leakage, which required waterproofing, flashing installation, and tile replacement, along with some bedroom ceiling sheetrock repairs, costing $6,000. More recently, there is an unresolved issue as of February 2024 with a collapsed sidewalk reported to the Department of Public Works. The building area has witnessed recurring parking enforcement issues, particularly involving sidewalk parking, with multiple citations and reports from 2019 through 2024, including a recent resolved citation in November 2023. Two vehicles were specifically noted for parking violations near the address, though many cases resulted in officers being unable to locate the offending vehicles.

Risk rating

How 638-640 24Th 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
98thpercentile

Out of 2250 buildings in this neighborhood, 45 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
