Initial analysis

The property at 1249 21st Avenue in the Central Sunset neighborhood is a two-story, four-unit multi-family residential building constructed in 1972, currently owned by Piotrkowski Tr. The building has undergone one major maintenance work on record, a reroofing project completed in 1990. Between 2000 and 2002, the property experienced multiple fire safety-related violations, including issues with combustible storage, smoke enclosure doors, and fire escape platform obstructions. All these violations were addressed and abated by September 2002, as confirmed through routine housing inspections conducted in June 2000 and August 2002. The most recent routine inspection was completed in September 2009, with no remaining violations noted.

In terms of external incidents and maintenance issues, the building's vicinity has been the subject of several 311 calls over the years, including a damaged tree report in 2015 (resolved through limb removal), graffiti on a pole in 2016, general street cleaning needs in 2013, and a damaged parking meter in 2009 (which was promptly serviced the following day). While these external issues were addressed, they primarily relate to public infrastructure rather than building-specific concerns. The property's documented history shows no recent building code violations or major maintenance issues in the past decade, with the last recorded housing inspection being routine and without noted deficiencies.

Risk rating

How 1249 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.

Neighborhood percentile
