Initial analysis

The three-story mixed-use building at 4058-4060 18th Street, constructed in 1901, features two residential units and commercial space, currently housing the Castro Country Club (formerly Blind Butcher) restaurant. Major renovations occurred between 2013-2014, including the conversion of a ground-floor garage to a restaurant, comprehensive fire safety improvements (sprinkler systems, ANSUL system, and fire alarm monitoring), and electrical upgrades. During this period, the building underwent significant infrastructural enhancements, including new plumbing installations, HVAC improvements, and electrical service upgrades.

Recent challenges have included multiple maintenance issues in the surrounding area, as evidenced by numerous 311 calls in late 2024 regarding garbage, debris, and waste management. Two notable noise complaints were filed in December 2024. Historical concerns include a 2014 violation regarding ventilation installation, which was resolved by 2018, and construction-related noise complaints in 2020. The property has maintained an active compliance record with fire safety regulations, addressing all documented fire complaints promptly, with the most recent fire-related issues recorded in 2023 being marked as duplicates or corrected conditions. The building's renovation and conversion projects have received appropriate permits and approvals, including Conditional Use authorization and compliance with all relevant planning and zoning regulations.

Risk rating

How 4058-4060 18Th 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.
