Initial analysis

The six-story, 21-unit apartment building at 436-438 Clementina Street, built in 2008, has experienced several significant maintenance and safety issues throughout its history, with the most pressing recent concerns centered around fire safety systems. Current and recent violations include a December 2023 violation regarding sleeping area requirements and an August 2024 violation concerning standpipes/missing caps. The building has a documented history of fire system-related issues, with multiple fire code violations recorded between 2017 and 2024, including problems with sprinkler/standpipe systems and alarm systems. Recent tenant complaints in early 2023 highlighted concerns about prolonged scaffolding use affecting unit views and privacy, though this issue was marked as resolved within a day.

Historical records show that the building underwent substantial fire safety modifications during construction, including the installation of numerous sprinkler heads and a comprehensive fire alarm system. The property has also experienced water-related issues, with complaints about ceiling leaks and floor water problems documented in 2010. While many violations and complaints from prior years have been resolved, there appears to be an ongoing pattern of fire safety maintenance challenges. The building's commercial space has been occupied by a bakery since 2012, and various plumbing and electrical improvements have been made over the years to maintain the property's infrastructure. Recent 311 calls from late 2024 suggest ongoing challenges with street cleaning and waste management in the surrounding area, though these are not directly related to the building's internal conditions.

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.

Neighborhood percentile

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.
