Initial analysis

The 3-unit multi-family residential building at 1115-1119 Union Street in Russian Hill, built in 1948 and currently owned by John & Athena Konstin Revoc, has undergone significant renovations and improvements over the past decade. Most notably, in 2012-2013, substantial work was completed including a major second-level remodel ($60,000) featuring kitchen and bathroom updates, deck installation, and comprehensive electrical work ($60,000) involving new circuits, lighting, and smoke detectors. The building received additional safety upgrades with the installation of 12 sprinkler heads in late 2013 ($6,000) and a complete reroofing project in 2016 ($18,750). Infrastructure improvements include the replacement of three heating systems and water heaters in 2014, installation of on-demand water heaters, and a new fireplace.

The building's maintenance record shows attention to both basic upkeep and safety enhancements, though there were some violations in 2004-2008 that have since been resolved. These included issues with security features (deadbolts), handrails, stairs, and lead paint concerns, all of which were abated by April 2008. A more recent complaint from 2019 regarding generator noise during construction work suggests ongoing maintenance activities, though this issue was also marked as not active. The property has undergone significant modernization while maintaining compliance with building codes, as evidenced by the numerous permits and successful completion of major systems upgrades.

Risk rating

How 1115-1119 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.
