Initial analysis

The property at 151 Valley St is a two-unit, single-story multi-family residential building located in Noe Valley, built in 1948 and currently owned by William J Wehrmeister. The building has undergone several significant improvements over the past two decades, including a window replacement project in 2015 that upgraded both front-facade and rear-facing windows with aluminum-clad wood windows at a cost of $20,639, and a roofing project in 2010 with a budget of $8,000. The plumbing infrastructure was updated in 2012 with the installation of a new 40-gallon gas water heater, replacing the old unit.

The property has experienced various maintenance and infrastructure issues in recent years, with the most notable incident being a sewage backup problem reported in December 2020 that was resolved by the PUC Sewer Operations team. The building's vicinity has seen recurring parking violations, particularly between 2020-2021, with multiple citations issued for sidewalk parking and driveway blocking incidents involving various vehicles. The area has also faced some quality-of-life challenges, including graffiti (in 2021 and 2024) and street cleaning issues (in 2020). While these incidents are worth noting, most have been promptly addressed by city enforcement agencies.

Risk rating

How 151 Valley 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
