Initial analysis

The 21-unit, three-story apartment building at 3515 Fillmore Street in the Marina district, owned by Dennis & Michelle Trimble T, was constructed in 1926 and has undergone several significant renovations and improvements over the past two decades. Most recently, two ADUs were added in 2020-2024, with the ground floor renovation including a new half bath in the common area garage. The building successfully completed its mandatory Soft Story retrofit in 2016 with the installation of shearwalls and moment frames, achieving Tier 2 status and receiving its Certificate of Final Completion. Historical improvements include the replacement of 83 vinyl windows in 2009, a complete reroofing in 1992, and the installation of a new sprinkler system in 2018-2019. The property has faced some compliance issues, including multiple fire safety violations related to fire escapes, sprinklers, and extinguishers between 2018 and 2024, though all have been marked as corrected or abated.

Recent improvements to the building's infrastructure include electrical work completed in late 2023 and new plumbing installations in early 2024. The building has experienced some maintenance challenges, with multiple 311 calls in 2024 regarding garbage and debris on the property. While there have been several fire-related incidents recorded, including smoke scares and minor kitchen fires, none resulted in civilian injuries. Historical violations from 2001-2006 related to boiler operations, backflow devices, and fire proofing requirements were eventually resolved. The building's current permits and recent maintenance work suggest ongoing attention to property improvements and code compliance, with particular focus on updating common areas and addressing infrastructure needs.

Risk rating

How 3515 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
