Initial analysis

The property at 1645-1649 Castro Street is a two-story, four-unit multi-family residential building with ground-floor commercial space, constructed in 1900 in the Noe Valley neighborhood. The building has undergone several significant maintenance and improvement projects over the past few decades, including termite repairs in 2017 ($9,700), a complete reroofing in 2011 ($24,000), window replacements in 2002 ($4,000), and a major remodel of the upstairs apartment bathroom and kitchen that same year ($6,500). Earlier structural work included stucco replacement in 1992 and a house trap installation in 2008, demonstrating ongoing attention to the building's maintenance needs.

Recent external conditions around the property have raised concerns, particularly in late 2024, with multiple reports of overflowing city garbage cans and debris issues in the immediate vicinity, with at least ten documented incidents between October and December 2024. While these external sanitation issues have been consistently resolved by city services, they represent a pattern of neighborhood maintenance challenges. The building's owner, Alice J Sacca 2008 Revoc Trust, has maintained active ownership through regular permit filings for necessary repairs and upgrades, though it's worth noting that some earlier permits from 1998 and 2002 show as expired rather than completed. The most recent planning record indicates an accepted ABC referral for a Type 21 application at 1649 Castro Street, though no developer information is provided.

Risk rating

How 1645-1649 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.
