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 2013
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Likely exempt from AB 1482. Housing with a certificate of occupancy issued within the previous 15 years is exempt from the state rent cap and just-cause rules.

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 4-unit apartment building at 543-547 Grove Street in Hayes Valley, owned by Golden Properties LLC, was constructed in 2013 and is a 4-story multi-family residential building. The property has undergone significant safety improvements during its lifetime, with the installation of comprehensive fire safety systems in 2012-2013 including fire sprinklers throughout the building, a fire alarm system with control panel and detectors, and dedicated sprinkler monitoring equipment. The building has received multiple infrastructure upgrades, including new furnaces, water heaters, and plumbing improvements such as new bathrooms and kitchen installations for all units. More recent events include a complaint about construction noise during Memorial Day weekend in 2023, which was the most recent building complaint on record.

The property's earlier history includes several violations in 2002 related to interior surfaces, plumbing, and fire safety, though all were abated by 2004. There were also multiple building permits issued in 2012-2013 for various improvements, including the installation of a sump pump in the garage, electrical system upgrades, and the replacement of a broken window in the rear ground floor unit. The building's electrical system features a comprehensive setup including 400-amp service and multiple subpanels, installed during the 2012 construction phase. Recent maintenance issues have centered around parking enforcement, with multiple citations issued in 2024 for driveway blocking, though these are not directly related to building safety or habitability. Two minor fire-related incidents were recorded, including a carbon monoxide detector activation and a toxic condition event, neither resulting in civilian injuries.

Risk rating

How 543-547 Grove St'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
61stpercentile

Out of 1027 buildings in this neighborhood, 401 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.
