Initial analysis

The two-story, three-unit multi-family residential building at 1021-1025 Lake Street, owned by Koburov Tr, has undergone significant renovations and improvements since its construction in 1912. Most notably, in late 2023, the building underwent facade and window improvements, including the removal of a non-historic brick facade and replacement with matching stucco, along with window and door replacements, with a $40,000 permit cost. Between 2012 and 2014, substantial unit improvements were completed, including kitchen and bathroom renovations in units 1025 and 1023, an interior remodel on the third floor, and installation of new electrical systems throughout. The building has had proper maintenance of essential systems, with roof replacement in 2014, exterior stair repairs in 2016, and plumbing work including sewer repairs in 2008.

The property has experienced some challenges, particularly regarding its sewer systems, with multiple sewer backup incidents reported through 311 calls in April 2022. A building fire with equipment failure as the ignition source was recorded, though with no civilian injuries reported. Two routine housing inspections in 2001 and 2008 were completed and marked as abated. Recent building improvement activities include attempts to enhance insulation and stucco finishes, though a permit for these revisions was withdrawn in December 2023. The building's location has seen frequent parking enforcement actions, with multiple citations issued for driveway blocking between 2021-2024, as well as one incident involving a damaged tree that could not be removed due to graffiti concerns. While there have been maintenance and safety incidents, the overall pattern suggests regular upkeep and modernization efforts by the owners, with most building permits marked as complete and proper handling of major systems upgrades and repairs.

Risk rating

How 1021-1025 Lake 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 660 buildings in this neighborhood, 323 are predicted to be safer.
