Initial analysis

The Nuerge Living Trust owns this 2-unit, 3-story multi-family residential building located at 3940-3942 Clay Street in Presidio Heights, constructed in 1914. The property has experienced notable developments in recent years, with two active housing complaints filed in May 2024 regarding work being performed without proper permits on the rear building's roof structure, including claims of dangerous work practices and illegal construction with inadequate setbacks to neighboring homes. These complaints remain active as of this report's creation. The building's maintenance history includes a $30,000 underpinning pier installation in 2015 related to neighboring excavation, and a reroofing project from 1996, though this permit has expired.

The property has generated multiple parking-related complaints between 2022 and 2025, with several incidents of vehicles blocking driveways, double parking, and parking on sidewalks, though most of these cases have been resolved through citations or other enforcement actions. There were also some street maintenance issues documented through 311 calls, including reports of overgrown trees (which were determined not to be the City's responsibility), loose garbage, and general cleaning needs. A fire alarm incident was recorded at the property with no actual fire or civilian injuries involved. While the building's structural concerns raised in 2024 warrant attention, the property's historical maintenance record shows some attention to major systems like the roof and foundation reinforcement.

Risk rating

How 3940-3942 Clay 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.
