Initial analysis

The 321-323 Collingwood Street property is a four-story, three-unit multi-family residential building constructed in 1924 and currently owned by the Chatterjee Family 1997 Trust. The building underwent significant renovations in 2014-2015, including a comprehensive remodeling of all units costing $234,000, followed by various structural improvements such as foundation repairs at five locations ($20,000), replacement of a cracked retaining wall ($10,000), and a complete roof replacement ($10,400). The renovation period also included substantial electrical upgrades, with the installation of new 225-amp overhead service and comprehensive wiring improvements across all units, as well as plumbing enhancements including bathroom remodels and radiant heating installation.

The property has a history of maintenance and safety compliance issues that were addressed in early 2008, including the installation of fire extinguishers, gas shutoff tools, smoke detectors, handrails, and garbage receptacle relocation. While all these violations were officially abated by February 2008, recent records from September 2023 indicate recurring issues with sidewalk parking violations in the vicinity, involving a specific vehicle (blue Audi - 9GBE978). The building's recent history has shown active maintenance and upgrading work, with all major permits from 2014-2015 being completed, including plumbing and electrical systems modernization. The property has maintained compliance with housing codes since resolving the 2007 violations, with no recent building code violations or major maintenance issues on record.

Risk rating

How 321-323 Collingwood 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.

Neighborhood percentile

Neighborhood location
