Initial analysis

The three-unit multi-family residential building at 622-626 Hyde Street, constructed in 1910, has undergone several significant maintenance and safety-related improvements over its history. Most notably, a substantial roofing project was completed in May 2018 at a cost of $9,800, which included the removal of old roofing layers, installation of fiberglass base, bitumen membrane application, and top coating. The building's parapet safety compliance was addressed in 1986, and it has passed routine housing inspections, with the most recent on record from 2003 showing no active issues. The property has experienced multiple fire safety system activations, primarily involving smoke detectors and alarm systems, though all incidents were determined to be unintentional or due to malfunction, with no civilian injuries reported.

In recent years, particularly from 2021 through 2024, there have been numerous calls and complaints regarding the surrounding street conditions, including multiple reports of human waste, debris, and abandoned items, particularly mattresses, though these issues primarily relate to the street rather than the building itself. A noise complaint was filed in May 2024, which was advised to be handled by SFPD, and there was one encampment cleanup in February 2022. The most recent building-related permit activity was a street space permit issued in May 2018. While the building's maintenance record shows attention to structural and safety requirements, the external environment has experienced ongoing challenges with street cleanliness and safety, though these are more reflective of neighborhood conditions than building-specific issues.

Risk rating

How 622-626 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

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 47.3%
Moderate concern 17.7%
