Initial analysis

The property at 3274-3294 26th Street, a two-story multi-family residential building constructed in 1902, contains 8 units and is currently owned by the Philip & Jean Ishimaru family. The building's permit history reveals several significant maintenance and improvement projects, including a complete reroofing project in 2015 costing $56,942 and the addition of attic draft stopping to improve unit separation in the same year. The property has experienced recurring heating system issues, with three separate complaints in 2011, 2017, and most recently in December 2023, where residents reported inadequate heating and temperature control, with interior temperatures dropping to as low as 59°F despite using space heaters. The building also faced notable maintenance challenges in 2023, including water damage and interior surface problems, which were officially documented but later abated by May 2023. The residential space underwent a kitchen remodel in 2011 that included various plumbing and electrical improvements. While the property has a history of routine maintenance and repairs, including window and door seal improvements, more recent complaints suggest ongoing concerns with building envelope performance, particularly regarding heat retention and moisture management.

The building's historical records indicate proper response to violations, with most being abated within several weeks of notification. Fire incident records show minimal issues, with only routine system activations and no civilian injuries reported. The property has also been involved in some external maintenance matters, as evidenced by numerous 311 calls between late 2024 and early 2025 regarding street cleaning and debris removal, though these are generally external to the building itself. The building's age and maintenance history suggest regular upkeep, though recent heating and moisture issues have emerged as persistent concerns.

Risk rating

How 3274-3294 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 2380 buildings in this neighborhood, 2118 are predicted to be safer.
