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 2017
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 residential building at 4126 17th Street in Corona Heights, owned by Golden Properties LLC/4126, was constructed in 2017 as a 3-story apartment building with one additional detached unit at the rear, following the demolition of a previous structure. The development process was marked by several significant construction period complaints between 2015 and 2016, including issues with unsafe scaffolding, construction debris, security concerns, and sidewalk conditions affecting disabled access. These complaints were eventually resolved, and the building's monitoring systems were upgraded with a complete fire alarm system installation in 2016, including smoke detectors, pull stations, and water flow monitoring modules, along with new electrical systems and apartment amenities completed in 2015.

The building's recent history shows normal operational maintenance with some recurring issues, as evidenced by multiple 311 calls in 2023-2024 primarily concerning garbage and debris on the property grounds. The property underwent various infrastructure improvements, including the installation of a standard EV charger in 2021 and recent plumbing updates. While there were historical building code violations related to vacant building registration and exterior maintenance (2010-2012) which have since been resolved, the property currently has no active building violations. All recent construction and installation work, including safety systems, electrical infrastructure, and plumbing systems, has been properly permitted and completed according to regulations, though some original construction-related complaints from 2016 regarding building height and facade materials were filed but not actively pursued.

Risk rating

How 4126 17Th 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
24thpercentile

Out of 348 buildings in this neighborhood, 264 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.

Number of units

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
