Initial analysis

The property at 218 Union Street is a 4-story, 7-unit multi-family residential building constructed in 1963 and currently owned by Kristofer M. Votruba. The building has undergone several significant modifications and improvements over the years, with a particular focus on the roof deck area. Most recently, in October 2023, a permit was filed for a 1-hour parapet structure at the property line of the roof deck and urban garden. This follows a history of roof-related compliance issues, including a 2021 violation regarding unpermitted privacy screens and seating on the roof deck, which was subsequently legalized with a $2,000 permit. The building has completed mandatory seismic retrofitting and related improvements valued at $20,000 in 2015, and electrical system upgrades including the installation of new sub-panels for multiple units in 2016 and a solar PV system in 2014.

The building's maintenance history shows attention to safety concerns, with multiple permits related to fire safety improvements, including fire wall construction and emergency lighting installations. Notable compliance issues have included several violations regarding unpermitted construction and safety concerns, particularly related to the roof decks, which have been addressed through subsequent permits and changes. A 2019 complaint regarding potential lead paint concerns was filed, as well as various tenant-related complaints regarding appliance installations and maintenance issues that appear to have been resolved. The building successfully completed its Tier 3 soft story retrofit requirements and received a Certificate of Final Completion. Two fire-related incidents were recorded, but both were false alarms with no reported injuries. Recent activity at the property includes several 311 calls regarding parking issues and building maintenance matters, with the most recent being a request for service filed in October 2023.

Risk rating

How 218 Union 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

Out of 684 buildings in this neighborhood, 629 are predicted to be safer.
