Initial analysis

The building at 64-70 Langton Street is a 2-story, 4-unit multi-family residential apartment building constructed in 1917 and currently owned by Clinton James. The property has experienced recurring fire safety violations and concerns over the past several years, with the most recent violations in 2024 related to sleeping area requirements and standpipe systems. Between 2021 and 2024, the building received multiple fire code violation notices regarding alarm systems, extinguishers, and general fire safety compliance, though many of these issues were subsequently corrected. Historical records indicate significant safety concerns were addressed between 2003-2004, including the installation of fire sprinklers, fire extinguishers, and emergency egress requirements, following a period during which the building was discovered to have unauthorized unit conversions and missing safety features.

Recent maintenance issues have been documented through 311 calls and inspections, including three open reports from December 2024 regarding a missing side sewer vent cover. The most recent building permit activity was in 2016, related to shoring and excavation work. The property has a history of both building and fire code violations, starting with a series of fire safety issues in 2003-2004 that led to corrections of various safety features. An extensive renovation occurred in 2008 that included exterior stair repairs, kitchen remodeling, sprinkler system modifications, and electrical upgrades, suggesting efforts were made to bring the building up to code following earlier violations. The building has experienced occasional fire incidents, though none have resulted in civilian injuries, and the most recent complaints suggest ongoing attention is needed for fire system maintenance and safety compliance.

Risk rating

How 64-70 Langton 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.

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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 53.8%
Moderate concern 24.7%
Severe concern 21.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
