Initial analysis

The property at 590-594 Lombard Street is a 2-story, 3-unit multi-family residential building located in North Beach, owned by Purvin Colton and originally constructed in 1926. The building has undergone significant renovations and improvements over the past decade, including comprehensive plumbing updates in 2017-2018 that replaced systems in all three units' bathrooms, kitchens, and laundry rooms, as well as the installation of a new underground fire service and sprinkler system. Electrical upgrades have included kitchen and bathroom remodels, full rewiring of multiple living spaces, and the recent installation of a solar inverter and battery backup system for sump pump maintenance in 2021.

The building has experienced several notable compliance issues, particularly between 2016-2019. There were multiple instances of work being performed beyond the scope of permits, including unauthorized roof deck modifications and garage height adjustments, which resulted in violations and required correction. A 2017 violation related to the rear roof deck and vacant building status was ultimately abated by November 2018. More recently, there have been three junk removal cases in 2024, though these appear to be external to the building itself. The property has received multiple street space permits between 2017-2018, indicating ongoing exterior maintenance and improvements. While a 2019 Fire Violation was issued regarding the alarm system, this was subsequently abated, and there have been no reported fire incidents resulting in injuries. The building's records show regular maintenance and upgrading of systems over time, with most historical violations having been resolved.

Risk rating

How 590-594 Lombard 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.
