Initial analysis

The property at 4119-4121 26th Street in Noe Valley is a three-unit, multi-family residential building constructed in 1979, currently owned by the J D Aw Revocable Trust. The building has experienced several significant issues over the past decade, most notably a roof fire in October 2019 that required $2,000 in repairs. The building has undergone multiple modifications and corrections related to its unit configuration, including the removal of unauthorized cooking appliances and electrical connections between 2013-2016, which were part of enforcement actions following violations. These corrections addressed concerns about improper unit conversions, as the building was originally permitted as a two-family dwelling with garage/storage basement but had been operating as a four-unit building without proper approvals, causing fire safety concerns including lack of required second means of egress.

More recently, the building has faced ongoing waste management challenges, with multiple reports of overflowing city garbage cans and debris issues between 2023-2024, with seven such incidents reported through 311 calls in the past year alone. While these waste management issues are not directly related to building safety, they may affect resident quality of life. The property underwent a significant compliance process in 2016-2017 that included the removal of an unpermitted dwelling unit, bringing the building back into compliance with its original two-family configuration according to Planning Records, and addressing illegal short-term rental activity that was previously occurring in one unit. The building appears to be currently free of active violations, though some ongoing maintenance and management issues persist as evidenced by the recent 311 calls regarding waste management.

Risk rating

How 4119-4121 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

Out of 1879 buildings in this neighborhood, 1259 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 65.5%
Moderate concern 22.4%
Severe concern 12.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
