Initial analysis

The property at 1383 21st Avenue in the Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1940, currently owned by the Jung Family Trust. The building has experienced significant maintenance issues, particularly evident in early 2024 when multiple violations were issued, including problems with mold/mildew on walls, damaged walls, weatherproofing issues with siding, and various other maintenance concerns. These violations, filed on February 26, 2024, were all officially abated by July 12, 2024, suggesting remediation efforts were undertaken. During this period, the owners filed multiple building permits to address structural and safety concerns, including repairs to dry rot on decks and stairs, roofing work, and other maintenance tasks totaling approximately $19,000 in permitted work. A significant complaint was logged by tenants in February 2024 regarding water intrusion, window issues, peeling paint, and balcony deterioration, though records indicate that about 20-25 contractors had previously inspected the unit. An electrical upgrade was completed in 2013 for the ground level breezeway, and three complaints regarding an alleged illegal unit downstairs were filed in June 2013, though these were subsequently closed without resolution. The front windows, mentioned in multiple complaints, were reportedly experiencing issues with water damage and swelling. The building has a history of various maintenance and compliance issues that require monitoring, although recent permits and completed work suggest active management of some of these concerns.

Risk rating

How 1383 21St Ave'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.
