Initial analysis

548 Columbus Avenue is a two-story, mixed-use building constructed in 1906, featuring both residential (2 units) and commercial space, currently owned by Intl Settlement Holding Corp. The property has undergone several significant improvements and modifications over the past decade, with the most recent major renovation completed in 2022 costing $35,000, which included bathroom and kitchen remodeling, electrical upgrades, flooring replacement, and interior repainting. The commercial space has seen substantial transformation, particularly in 2017 when a salon was converted into a pasta making and distribution retail space, involving comprehensive plumbing and electrical work valued at $40,000, along with the installation of a new sign and retractable awning. During this period, the building also received important infrastructure upgrades, including a new furnace installation and various plumbing improvements.

The property has experienced several fire safety-related incidents and violations, most notably in 2024 when multiple fire code violations were issued regarding alarm systems and fire safety equipment, though these were subsequently addressed and abated. A pattern of fire safety concerns is evident from records dating back to 2010, including issues with blocked exits, exit maintenance, and the need for proper alarm system maintenance, though most of these violations have been resolved. The building's commercial space holds an ABC Type 21 license for specialty grocery sales, with specific restrictions regarding food manufacturing on the premises. Recent 311 calls from late 2024 and 2025 indicate ongoing issues with garbage and debris management around the property, as well as some concerns related to delivery service noise. The building's maintenance record shows regular upkeep, including roof work in 1996 and various other improvements over the years, suggesting active management of both residential and commercial spaces.

Risk rating

How 548 Columbus Ave'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
