Initial analysis

The two-unit residential building at 55-57 Valley Street in Noe Valley, owned by Sagarika Chalasani, has undergone several notable maintenance and improvement projects since its construction in 1988. Most recently, a significant reroofing project valued at $28,000 was permitted in July 2024, indicating ongoing maintenance of the property's infrastructure. Historical improvements include a garage renovation in 2001, where the front doors were replaced with 21-foot aluminum/glass sectional rollups, and modifications to a rear deck in 2000, which involved raising its height from 10 to 12 feet and included foundation work under the garage. The building's permit history also shows attention to street space management in 2011, with two permits issued for this purpose.

The property has experienced multiple parking-related incidents in recent years, with six recorded cases between 2021 and 2024, including two sidewalk parking violations in 2024 and a verified driveway blocking incident in 2022 that resulted in a citation. Other service requests include a water quality inquiry in February 2021 that was accepted by the Water Quality department, and a street cleaning sign repair in 2013. An abandoned vehicle complaint from 2012 was resolved when the vehicle was no longer present upon inspection. The building's permit and service call history suggests regular maintenance and response to local conditions, with particular attention to parking regulation enforcement in the immediate vicinity.

Risk rating

How 55-57 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.
