Initial analysis

The three-story, six-unit multi-family residential building at 667-671 Castro Street, owned by Castro 667 LLC, was constructed in 1906 and has undergone significant seismic safety improvements in recent years. Most notably, the building completed a mandatory soft-story retrofit in 2017-2020, including new plywood shear walls and foundations, demonstrating compliance with San Francisco's seismic safety requirements. The property has seen several major improvements, including the addition of an accessory dwelling unit in 2018 valued at $214,000, and a reroofing project currently permitted for $14,800 in 2024. However, the building's history includes several concerning tenant experience issues between 2020-2021, including complaints about construction noise during the COVID-19 pandemic, which allegedly violated emergency ordinances, and a brief period in 2006 when multiple Housing Code violations were documented, including issues with egress obstruction, stairs, water heaters, rodent infestation, and fire safety concerns - all of which were abated by October 2006.

In 2023, there was a fire complaint regarding blocked exits, though this was determined to have "No Merit." The building's fire safety systems have been tested in recent years, with three documented incidents (smoke detector activation, carbon monoxide detector activation, and smoke removal) recorded, none resulting in civilian injuries. The property has maintained compliance with its soft-story retrofit requirements, achieving a "Work Complete, CFC Issued" status. Recent maintenance includes regular response to street cleaning needs and addressing encampment reports in the vicinity, though these are external to the building itself. The permit history and inspection records suggest ongoing investment in building improvements and compliance with safety regulations, though periodic tenant complaints indicate some challenges with construction management and property maintenance over the years.

Risk rating

How 667-671 Castro 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
