Initial analysis

The property at 530-534 Buchanan Street in Hayes Valley is a two-story multi-family residential building constructed in 1908, containing three units. The building's recent history has been marked by significant maintenance issues, most notably a complaint filed in October 2023 regarding disconnected downspouts causing rainwater to enter windows, which remains in a not-active status with Housing Inspection Services. The roof has undergone recent work, with a $9,500 reroofing project completed in 2021, following an expired roofing permit from 1998. Historical records indicate various maintenance and improvement efforts, including bathroom remodeling and dry rot repairs in 1989, termite repairs in 1987, and unsuccessful attempts to establish a laundromat in the same year.

The surrounding area has experienced a series of environmental and safety incidents over the past few years, with the most notable issues occurring in 2024, including multiple instances of hazardous liquid spills requiring street cleaning services. Other recent concerns include reports of medical waste (needles) in 2023, graffiti on a bike rack, and several illegal parking incidents. The property owners, Tieu Holman & Nguyen Hoa Ki, have maintained permits for various improvements over the decades, with the most significant recent work being the roof replacement in 2021, though the building's age suggests ongoing maintenance challenges are to be expected. The street-facing portion of the property has faced urban environmental challenges typical of the Hayes Valley neighborhood, including issues with debris, hazardous materials, and illegal parking, though these street-level concerns are generally managed through city services and not directly related to the building's condition.

Risk rating

How 530-534 Buchanan 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.
