Initial analysis

The property at 2309-2311 24th Avenue is a two-unit, two-story multi-family residential building constructed in 1926, currently owned by Aleck Chan. This Parkside Flats & Duplex building has undergone several significant improvements over the years, with the most notable being the installation of a solar power system in 2017 comprising 13 PV modules with a total capacity of 4.615 kW, representing a modernization of the building's energy systems. In 2004, substantial renovations were completed including repairs to the backyard deck and stairs, along with the addition of new storage and a half-bathroom on the ground floor, costing approximately $20,000. Earlier modifications were made in 1997 when 1/2-inch plywood was installed on the garage walls.

The building's recent maintenance history shows attention to various infrastructure needs, including electrical upgrades such as additional outlets for a bathroom, storage room, and gas heater in 2005. The surrounding area has experienced typical urban maintenance issues, with several 311 calls between 2012 and 2024 primarily related to street cleaning, general maintenance, and infrastructure concerns. These include reports of garbage (most recently in July 2024), a curb defect (March 2023), and various park maintenance issues. Notably, there have been no serious complaints or incidents related to the building's structural integrity or safety over this period, and all reported issues have been officially resolved through appropriate channels, suggesting regular municipal oversight of the property's vicinity.

Risk rating

How 2309-2311 24Th 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.
