Initial analysis

The property at 314 21st Avenue is a three-story, two-unit multi-family residential building located in San Francisco's Central Richmond neighborhood, owned by Maeghan Kelly Kossar and constructed in 1920. The building underwent significant renovations in 2012-2013, including a comprehensive $55,000 unit conversion project that reconfigured bedrooms and bathrooms across two floors, as well as a substantial kitchen and bathroom remodel ($62,000) that included window replacements and stucco repairs. During this renovation period, major safety upgrades were implemented, most notably the installation of a new fire sprinkler system throughout the building ($18,000), along with electrical system updates including new services for unit #1 and installation of modern fixtures and safety equipment.

More recent history shows attention to basic infrastructure maintenance, including reroofing work in 2012 and garage door replacement. The building has experienced four minor fire-related incidents, all of which were either false alarms or contained cooking fires, with no civilian injuries reported. Recent municipal service calls in 2024 have primarily concerned street maintenance and parking enforcement issues in the vicinity of the building, with three notable cleaning-related calls between February and March 2024, and two documented instances of sidewalk parking violations. Of particular note is a January 2024 report of a collapsed sidewalk, though city inspectors found no such condition during their follow-up inspection. The property has maintained active compliance with necessary permits and inspections, though there was a single complaint filed in 2012 regarding an unpermitted garage door replacement, which was subsequently addressed through proper permitting processes.

Risk rating

How 314 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.
