Initial analysis

The property at 4043-4045 26th Street in Noe Valley is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Mary L and Ronald Baird. The building has undergone several significant structural improvements over the past three decades, including a foundation replacement in 1999, reroofing in 1993, and deck replacement in 2003. More recent maintenance work in 2012 addressed issues with wall rot and installation of shearwalls and post-beam connectors on the left property line. A furnace replacement was completed in 2007, following a serious incident in October 2007 when the furnace was disconnected by PG&E due to high carbon dioxide readings, leaving tenants without heat. This period also saw multiple housing violations related to water damage, wall repairs, and heating system requirements, all of which were abated by February 2008.

The building's maintenance history includes attention to both structural and mechanical systems, though the property experienced notable plumbing issues in 2007, including water damage and heating problems. The most recent building permit activity on record is from 2012, suggesting no major structural modifications have been undertaken in the past decade. While there have been regular 311 calls regarding parking violations in the vicinity of the property between 2019 and 2024, these relate to street parking issues rather than building maintenance or resident concerns. The lack of recent building violations or major repairs could indicate either good maintenance practices or a lack of recorded permits, though no direct correlation can be drawn from this data alone.

Risk rating

How 4043-4045 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, 225 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 age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 86.1%
Moderate concern 9.3%
Severe concern 4.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
