Initial analysis

The two-unit residential building at 1862-1864 Union Street in Cow Hollow, owned by Blk Properties Inc, has undergone several significant improvements since its 1906 construction. Most notably, in 2019, the building received substantial structural reinforcement with a $50,000 foundation replacement along the west side, converting from brick to a more robust concrete grade beam foundation. The ground floor retail space has seen considerable recent activity, including a 2018 alteration and storefront replacement valued at $104,000, followed by electrical upgrades including the installation of numerous new outlets, switches, and lighting fixtures. A foundation-related complaint was filed in May 2018 regarding potential undermining from neighboring excavation, though this issue appears to have been resolved.

The property has maintained an active maintenance and improvement record, with earlier work including a 2003 retaining wall replacement costing $35,000, and various urban maintenance responses to street-related issues such as pavement defects, illegal postings, and graffiti removal in the surrounding area. Two significant planning proposals have been noted: one involving the removal of a non-historic storefront in favor of new aluminum storefront construction for retail tenant Kryolan, and another regarding the possible relocation and remodeling of residential units at the rear of the property. The most recent service calls have primarily related to street-level concerns rather than building-specific issues, with the latest being a bicycle sharing operations complaint in June 2023.

Risk rating

How 1862-1864 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
