Initial analysis

The two-unit residential building located at 2363-2365 21st Avenue in the Parkside neighborhood is a two-story flats and duplex structure built in 1926 and currently owned by the Tina & Mason Lee Family Trust. The property has undergone several permitted improvements over the years, including completed kitchen renovations in 1997, electrical upgrades in 2004 (installation of 30 lights and 15 switches), garage improvements in 2003 with seismic reinforcement ($25,000), and more recently, a street space and sidewalk permit issued in 2010. Noteworthy though less recent work includes a stairway replacement project from 1999, which has since expired.

The building has experienced significant issues with driveway access in 2024, with multiple parking enforcement calls recorded throughout the year. Between April and October 2024, there were at least ten separate incidents of driveway blocking reported, resulting in several citations being issued, though in many cases officers were unable to locate the offending vehicles. This pattern of parking violations suggests ongoing challenges with driveway access, though these incidents are more related to public street parking issues rather than building safety concerns. The only recorded fire-related incident was a combustible materials complaint in July 2009, which was investigated and found to have no merit.

Risk rating

How 2363-2365 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
71th percentile

Out of 255 buildings in this neighborhood, 74 are predicted to be safer.

Neighborhood location

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 58.2%
Moderate concern 22.9%
Severe concern 18.9%
