Initial analysis

The 10-unit, 2-story apartment building at 4125 26th Street in Noe Valley, owned by Fellom Family Fund Llc, has undergone several significant structural and safety improvements since its construction in 1960. Most notably, the building completed mandatory soft-story retrofit work in 2018 (Tier 3, Work Complete, CFC Issued) and addressed erosion concerns in 2021 by installing deep piers and a concrete retaining wall with a drain field in the backyard. The property has experienced recurring foundation erosion issues between 2018-2022, affecting both this building and neighboring properties, resulting in multiple complaints and inspections.

The building's safety systems have been a focus of attention, with several fire safety improvements implemented over the years, including the installation of fire sprinklers in the garage in 2007 ($6,000 project) following a concerning incident in 2007 involving excessive storage and a fire. Recent fire safety compliance issues were noted in 2024 with violations regarding the alarm system, though these were subsequently resolved. The property has undergone regular maintenance and safety inspections, with the most recent periodic health and safety inspection filed in April 2023 currently listed as active. Other improvements include various structural and maintenance work such as reroofing (1990), the addition of fire sprinklers (2007), and multiple street space permits. The building has also faced several administrative compliance matters over the years, including requirements to install self-closing doors and fire proofing repairs, though these violations are no longer active and have been addressed through various permits and inspections.

Risk rating

How 4125 26Th 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
