Initial analysis

239 26th Avenue is a 12-unit, 3-story multi-family residential building constructed in 1963, currently owned by Felipe Eduardo Diaz Gomez. The building has undergone several significant safety upgrades in recent years, most notably a fire alarm system upgrade completed in December 2023 at a cost of $57,900 to comply with updated fire safety requirements. The property has also successfully completed mandatory seismic retrofitting as a Tier 3 soft-story building, and in 2015, underwent a seismic retrofit with a $35,000 permit cost. In 2018, the building replaced its old boiler with an on-demand water heater, and in late 2022, installed a 40A EV charger.

The building underwent substantial interior improvements in 2008 when all 12 units received renovations to their kitchens, bathrooms, lighting, and other amenities, with individual unit improvements averaging $32,000 each. Three fire-related violations have been recorded over the years, with the most recent one from October 2024 regarding fire extinguisher servicing, while two previous violations from 2016 and 2018 were promptly corrected. The building has maintained compliance with regular inspections, though there were several boiler and fire safety-related complaints between 2008-2018 that were resolved. Recent 311 calls from 2023-2024 have primarily concerned parking enforcement issues, with multiple reports of driveway blocking, though these are outside the building's direct operations.

Risk rating

How 239 26Th Ave'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

Out of 660 buildings in this neighborhood, 620 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.

Building size

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 38.8%
Moderate concern 49.8%
Severe concern 11.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
