Initial analysis

The 3-story multi-family residential building at 750-760 Columbus Avenue, owned by Tomac Property Ventures LLC, was built in 1909 and contains 8 units. It has undergone significant structural and infrastructure modifications over the years, including several T-Mobile antenna installations and maintenance (most recently in 2020 with a $25,000 permit), a complete kitchen and bath remodel in 2016, and multiple plumbing improvements. The building faced serious plumbing issues in 2011-2012, including multiple sewage backup incidents, grease trap violations, and defective backwater valves that required enforcement intervention. While these violations were eventually abated, they indicated persistent maintenance challenges during that period.

Recent concerns have emerged as of 2023-2024, including an active complaint filed in September 2023 regarding unauthorized work on the store entrance and doors. The property completed its soft-story retrofit requirements as a Tier 4 property, receiving a CFC (Certificate of Final Completion). Fire safety compliance records show three violations related to exit obstructions in 2007, though these were marked as corrected. The building's utility infrastructure has been updated regularly, with electrical work including the removal of old equipment and installation of new systems, most recently in 2021. The property has also experienced various maintenance challenges as evidenced by multiple 311 calls in 2024 regarding sanitation issues in the immediate vicinity, though these are not directly related to the building's internal conditions.

Risk rating

How 750-760 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.
