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 21-unit, 6-story residential building at 436-438 Clementina Street, located in San Francisco's South of Market neighborhood and constructed in 2008, is currently facing several significant safety and compliance issues. Most notably, the building has active violations as of November 2025 requiring the submission of Section 604 affidavits to confirm the structural soundness of exterior building components exposed to the elements, following a recent inspection. The building experienced a serious incident in March 2025 when a kitchen fire rendered unit 601 uninhabitable, causing smoke, water, and fire damage, though repairs were subsequently undertaken with a permit valued at $3,000. Prior to this, there was considerable tenant concern in early 2023 regarding extended scaffolding use throughout the building, which lasted over 120 days beyond initial estimates and impacted tenant privacy and safety.

The building's recent history shows a pattern of maintenance and safety compliance challenges, with 223 311 service requests filed over seven years, including multiple reports of garbage and debris (with six such complaints in 2025 alone), and three fire incidents on record. The property has undergone three inspections by the Department of Building Inspection over this period, with one 2025 complaint specifically noting work being done without proper permits in relation to stairway safety. The recent Section 604 affidavit requirements suggest ongoing concerns about the building's exterior maintenance, though the property's basic infrastructure appears to be maintained through periodic permits, as evidenced by the fire damage repair work completed in 2025.

Risk rating

How 436-438 Clementina 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

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.

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 11.4%
Moderate concern 79.8%
Severe concern 8.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
