Initial analysis

The property at 3932-3934 26th Street in Noe Valley is a two-unit, two-story multi-family residential building constructed in 1910, currently owned by Lin Junsheng. The building has undergone significant safety improvements in recent years, most notably the installation of a comprehensive fire sprinkler system throughout the building in 2019 (cost: $27,300) followed by a new sprinkler monitoring system in late 2023 (cost: $8,655). The property has experienced multiple construction-related issues, particularly during 2018-2020, including complaints about unauthorized demo work, potential foundation disruption, and concerns about work being done beyond the scope of permits. These concerns were documented in several complaints and resulted in a Discretionary Review Application regarding proposed renovation and addition work, including a controversial fourth-level addition and roof deck.

More recent building permits from 2023-2024 indicate ongoing work and final inspections for various improvements, including plumbing and electrical upgrades. The property has required multiple permit renewals and final inspections for plumbing work initially permitted in 2019. Historical data shows previous violations between 2014-2018, including some building violations and nuisance designations related to construction issues, water intrusion, and abandoned structure concerns, though most of these violations have been marked as abated. Recent 311 calls from 2023-2024 primarily relate to parking issues near the property, with several citations issued for blocking driveways and sidewalk parking violations.

Risk rating

How 3932-3934 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.
