Most notably, between 2022 and 2023, the building received comprehensive fire safety upgrades, including the installation of a new fire alarm panel, manual alarms, smoke detectors, LF horns, and cellular monitoring systems, with the most recent revision adding additional horns to 1-bedroom apartments. Other recent maintenance work includes repairs to the back stairwell in 2022, which involved replacing damaged wood, and the complete replacement of a steam boiler in 2010.

The building has experienced several fire safety-related incidents, with alarm system activations recorded in 2017 and 2023, though both cases were resolved with the condition corrected. Historical records show multiple fire safety violations in 2006, including egress obstructions, fire extinguisher issues, and fire proofing repairs, all of which were abated by January 2007. The property has undergone various maintenance work over the years, including reroofing in 2013 and window replacements in 1992. Recent 311 calls related to the property include Sewer Issues (2022), General Cleaning (2023), and multiple parking enforcement requests (2024), suggesting occasional infrastructure and maintenance needs. The most recent planning record indicates completed repairs to the rear stair with no more than 50% wood replacement, showing ongoing attention to structural maintenance.

Risk rating

How 3637 Fillmore 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
31th percentile

Out of 988 buildings in this neighborhood, 682 are predicted to be safer.

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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 34.2%
Moderate concern 32.9%
Severe concern 32.9%
