Initial analysis

837 Fillmore Street is a 4-story, 9-unit multi-family residential building located in the Alamo Square neighborhood, owned by Felix & Ingrid Contreras and constructed in 1900. The property has undergone significant modifications and improvements over recent years, with the most pressing concerns emerging in 2023-2024. Notable recent issues include multiple gas-related incidents between July-August 2023, with reports of leaking stoves and gas appliances in various units, though some related complaints were subsequently closed. The building underwent substantial renovation in 2018-2020, converting commercial space to residential use and completing a seismic retrofit as a Tier 4 soft-story building. Recent construction activity includes the installation of a new fire sprinkler system in 2023 and ongoing kitchen remodeling in Unit #1 in late 2024.

The building has experienced recurrent maintenance challenges, particularly with its sewer system, evidenced by multiple sewer backup incidents and vent issues reported between 2021-2024. Fire safety systems have received attention, with inspections and corrections noted for extinguishers in 2023 and 2006, though a January 2025 alarm systems complaint was recorded. Historical records from 2007-2015 show various building violations related to safety equipment, handrails, and fire escape maintenance, all of which were subsequently abated. The property has also seen significant infrastructure improvements, including a new 2-inch fire service water line installation in 2023 and various plumbing upgrades, such as bathroom and kitchen renovations. While most major construction and safety requirements have been addressed, the recent gas appliance issues and ongoing sewer problems suggest areas requiring continued attention.

Risk rating

How 837 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.
