Initial analysis

The 2-unit residential building at 3969-3971 23rd Street in Noe Valley, owned by Jason S & Christy J Oliger, is a two-story flats and duplex structure built in 1900. The property has undergone several significant renovations over the years, with a major electrical upgrade completed in 2003-2005 that included complete rewiring of both units, service upgrades, and installation of new meters and panels. In 2006, there were structural modifications including a new rear stair installation and changes to shear wall types. More recently, the building has seen sustainable improvements, with the installation of a solar panel system and battery backup (Tesla Powerwall) in late 2022.

The property has experienced some maintenance and infrastructure challenges, including a sewage backup incident in October 2023 and a tree-related issue in February 2024. There has been recurring concern with parking violations in the vicinity, with multiple reports of sidewalk parking and blocked driveways between 2023 and 2024. The building received two rear yard variances related to deck and stairs modifications in the mid-2000s, which were approved. The most recent building system improvements demonstrate a commitment to modernizing the property with renewable energy infrastructure, while the solar installation permits show completed work with proper final inspections obtained.

Risk rating

How 3969-3971 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

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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 83.3%
Moderate concern 8.9%
Severe concern 7.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
