Initial analysis

The three-unit residential building at 1252-1256 Hyde Street in Nob Hill, owned by Richard & Diana Woo Leong 1, has undergone significant and repetitive work on its rear stair and porch structures over the past several years. Beginning in 2021, the property has seen four consecutive projects related to repairing and rebuilding rear stairs and porches, with the most recent activity occurring in September 2023 involving a $20,000 revision to rebuild and reconfigure the existing wood stair. These structural improvements demonstrate ongoing maintenance of essential egress pathways, though they suggest potential recurring issues with the rear access structures. The building also received comprehensive window upgrades in 1992, installation of new laundry room facilities in 2022 (including plumbing and electrical work), and underwent reroofing in 2015.

While the building's maintenance record shows regular upkeep of major systems, there is a concerning pattern of recent street cleaning issues in the surrounding area, with multiple reports of garbage, debris, and waste (including medical waste and hazardous materials like needles) recorded between 2022 and 2025. These external maintenance challenges, documented through multiple 311 calls, could potentially affect resident quality of life, though they relate to public spaces rather than the building itself. The property's only documented building violation occurred in 2009 regarding hot water heater seismic bracing, which was promptly resolved within one month. The building's age (constructed in 1909) and history of stair/porch work may suggest ongoing attention to maintaining safety and accessibility standards, particularly as these structures serve as critical means of egress for residents.

Risk rating

How 1252-1256 Hyde 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
