Initial analysis

The property at 480-498 Castro Street is a mixed-use building built in 1900, consisting of 9 residential units and commercial space, currently owned by Claire Investments, Inc.

Most recently, in October 2024, a bathroom remodel was initiated to update wiring to code and install new LED lighting throughout, with an estimated cost of $35,000. The building has seen substantial accessibility improvements, including the installation of a handicap stairlift in 2022.

The property has experienced some maintenance and compliance challenges, particularly in late 2015 and early 2016, when multiple violations were recorded related to rodent infestation, heating system issues, and various safety concerns. All of these violations were abated by December 2015. In 2023, there were several complaints regarding unauthorized work (now resolved), and there is currently an active complaint regarding common areas filed in May 2023. The building's mechanical systems have been regularly updated, including multiple water heater replacements (2015-2016), furnace system installations (2014-2016), and plumbing improvements. Notably, there have been some recent concerns about the Walgreens storefront's compliance with planning code transparency requirements, which was marked as "Abated" in 2024.

Risk rating

How 480-498 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

Out of 1278 buildings in this neighborhood, 1240 are predicted to be safer.
