Initial analysis

The property at 3231-3233 16th Street, located in the Mission Dolores neighborhood, is a two-story multi-family residential building constructed in 1910, currently owned by the Colm J Brennan Revocable Trust. The building underwent significant redevelopment beginning in 2018, when permits were issued to demolish an existing garage and shed, and construct a new four-story residential building containing five units at the front of the property. This new construction was completed with minimal commercial space, contrary to initial plans. The project included extensive fire safety upgrades in 2023, with the installation of a comprehensive fire sprinkler system throughout the building ($215,898) and a new fire alarm monitoring system ($23,918). The building now features a variety of unit types, including 2 two-bedroom, one-bath units, 1 one-bedroom, one-bath unit, and 2 studio units, with common hallways.

The property has undergone numerous improvements and renovations over recent years, including plumbing upgrades such as gas lines, floor heating systems, and waste/vent systems ($215,898). Multiple permits were issued for electrical work, including new service installation and kitchen renovations. While the building has experienced some maintenance issues in the past, including several graffiti incidents and a missing side sewer vent cover in 2018, these were promptly addressed by city services. The most recent building modifications, completed in 2023, involved significant internal improvements including changes to unit entries, kitchen relocations, bathroom renovations, and laundry closet additions. The building now meets current safety standards with modern fire safety systems and updated residential amenities. The property has maintained proper permits and inspections throughout its renovation process, with only one cancelled permit in 2020 related to kitchen remodeling.

Risk rating

How 3231-3233 16Th 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.
