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 1983
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 three-unit residential building at 425-427 43rd Avenue in San Francisco's Outer Richmond neighborhood, constructed in 1983, has undergone significant recent improvements and regularly scheduled maintenance. Most notably, in early 2024, the building received comprehensive safety upgrades including the installation of 101 new fire sprinklers throughout the property, with associated plumbing work completed by March 2024. The building has seen substantial interior and exterior modifications over the past three years, including a major renovation in 2021 valued at $290,000 that involved relocating living spaces across multiple floors, adding new bedrooms and bathrooms, and addressing front brick repairs. Additional improvements include the installation of new HVAC systems (ceiling cassettes) in late 2024, substantial plumbing updates across multiple floors, and electrical system enhancements to support the building's modernization.

The property's maintenance history shows attention to both safety and quality of life improvements, with recent work including kitchen and bathroom renovations, deck expansions, and basement improvements that added recreation and utility spaces. There have been two historical building complaints, one regarding potential work without permits in 2022 and another from 2014 about structural concerns, though both are listed as not active. The building's management has promptly addressed various maintenance issues, as evidenced by multiple resolved 311 calls, primarily related to parking enforcement and sidewalk maintenance. The property's records indicate it has been properly maintained according to current building codes, with recent permits showing compliance with modern safety requirements, particularly the fire sprinkler system installation which met NFPA 13 standards.

Risk rating

How 425-427 43Rd 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
73rdpercentile

Out of 1040 buildings in this neighborhood, 281 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
