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 2008
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 four-story, three-unit multi-family residential building at 1278 4th Avenue in the Inner Sunset was constructed in 2008 following the demolition of a previous single-family dwelling on the site. The building was equipped with modern safety features during construction, including a fire sprinkler system ($22,500), fire alarm system with smoke detectors ($3,500), and comprehensive electrical installations. Initial construction costs amounted to $573,293. Since completion, the building has undergone several maintenance updates, including interior improvements, heating system installations, and ventilation system modifications across all units. A significant maintenance issue occurred in 2016 when the building was cited for multiple violations related to fire safety and structural maintenance, including missing carbon monoxide alarms, fire extinguisher maintenance issues, and egress obstructions. These violations were all abated by March 2017.

Prior to the 2016 violations, there were several other notable incidents, including complaints about unauthorized construction in 2008 and 1999, and a concerning report in 2002 about garbage accumulation and security issues during the building's transition period between the old and new structures. The most recent building permit activity was recorded in 2012 for siding repairs on the building's rear facade. While the building has experienced various maintenance and compliance issues throughout its history, records indicate that these problems have generally been addressed, with no active violations or complaints as of the latest data. The property is currently owned by Ho Wai King & Zhu Liang Mei.

Risk rating

How 1278 4Th 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
53rdpercentile

Out of 1493 buildings in this neighborhood, 702 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.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Building size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
