The building has received multiple infrastructure upgrades, including a reroofing project in 2008, window replacements (1995), new furnace installation (2008), and electrical system improvements with multiple service upgrades (2010). The property has had consistent maintenance of its core systems, including plumbing and electrical upgrades, with the most substantial electrical work in 2007-2009 involving extensive rewiring, new circuits, and panel installations.

Notably, there has been a recurring pattern of street sanitation issues in the vicinity of the property, with multiple reports of human waste or urine between 2023-2024, though all cases were resolved by street cleaning services. Other exterior maintenance issues have included general garbage cleaning (2023-2024) and a single incident of graffiti in 2022, which was addressed by the city’s graffiti removal services. While these exterior issues don't directly affect the building's interior conditions, they do indicate ongoing challenges with the property's immediate surroundings.

Risk rating

How 437-439 Bartlett 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.
