Augrented Insights
Initial analysis

The 21-unit, 6-story residential building at 436-438 Clementina Street in San Francisco's South of Market neighborhood, constructed in 2008, has experienced several significant events in recent years, particularly related to safety and building conditions. Most notably, in March 2025, a kitchen fire occurred in unit 601, rendering the unit uninhabitable and requiring repairs that were later documented in a building permit with a construction cost of $3,000. Currently, there are active building violations from November 2025 requiring a Section 604 affidavit to be submitted regarding the inspection of exterior building components exposed to the elements, with a deadline set for January 20, 2026. The building has also faced challenges with extended scaffolding installation, with a complaint filed in February 2023 regarding the temporary structures' prolonged presence exceeding initial time estimates, causing privacy and safety concerns for residents.

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.

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

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
12thpercentile

Out of 430 buildings in this neighborhood, 378 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.

Neighborhood (ZIP code)

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