Initial analysis

The 4-unit multi-family residential building at 3901-3907 26th Street in Noe Valley, owned by the Esther Yee Revocable Trust, is a two-story apartment building constructed in 1922. The property has undergone several significant improvements over the years, most notably a bathroom remodel in 2021 ($10,750) that included lighting, fan replacement, and comprehensive plumbing and electrical work, followed by earlier updates including a kitchen renovation in 2001 ($15,000) and window replacement in 1986. The building experienced multiple housing code violations in July 2001 related to fire safety and security, including issues with self-closing doors, egress pathways, and fire extinguisher requirements, though all were resolved by August 2001. A subsequent fire safety complaint was filed in 2011 regarding inadequate fire extinguisher coverage, which was also addressed within one month.

Recent maintenance and safety issues have primarily centered around the building's exterior and surrounding infrastructure. As of 2024, there are ongoing concerns with the sidewalk area including defects, a sewage backup incident, and various street cleaning matters. The property has also experienced some parking-related issues, with multiple reports of blocked driveways in late 2023 and early 2024. Historical records show routine inspections and some compliance-related work being performed, including a 1983 permit to bring certain features into compliance, though this permit's final outcome is not specified in the records.

Risk rating

How 3901-3907 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, 1221 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.

Number of units

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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 57.6%
Moderate concern 24.4%
Severe concern 18.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
