Initial analysis

The two-unit residential building at 4065-4067 23rd Street in Noe Valley, owned by the Ewing & De Joya Family Trust, has a substantial historical record dating back to its 1906 construction. The property has undergone several significant improvements over the years, most notably a recent reroofing project valued at $19,500 initiated in April 2024. Previous enhancements include the replacement of four wood windows on the rear of the house in 2011 (which were not visible from the street), a bathroom remodeling project in 2006 that aimed to create two bathrooms and a new closet in unit #4067, and various structural repairs including stud replacements in 1990 and porch/stair reconstruction with termite repairs in 1987. The building's electrical system received upgrades in 2006, including the installation of lights, switches, receptacles, and a new circuit.

Of particular note is a recurring issue with driveway access, as evidenced by numerous parking enforcement calls over the past two years. Between August 2023 and October 2024, there were at least ten documented incidents of blocked driveways requiring parking enforcement intervention, with several resulting in citations and others being unable to validate the complaint. While these parking-related issues are external to the building's physical structure, they represent an ongoing challenge for residents regarding access to their property. The building's permit history suggests regular maintenance and upgrades, with most recent permits focusing on roofing and other essential improvements.

Risk rating

How 4065-4067 23Rd 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
76th percentile

Out of 1879 buildings in this neighborhood, 451 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 age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 74.2%
Moderate concern 14.0%
Severe concern 11.8%
