Initial analysis

The property at 410-412 24th Ave in the Central Richmond neighborhood is a two-story, 5-unit multi-family residential building constructed in 1904, currently owned by Lin Hua Yan. The building has undergone several significant modifications over the past decade, with the most recent being a commercial space conversion to a gym in July 2023, involving light fixture updates and minor electrical work ($8,000). The property has experienced multiple code compliance issues, particularly in 2023-2024, with active complaints regarding unpermitted work and an alleged illegal unit in the rear commercial space. These recent complaints cited unauthorized sheetrock installation, bathroom construction, and electrical work. Several historical violations were recorded in 2014, including hazardous electrical conditions, glazing issues, and water damage, though these appear to have been resolved. The building has undergone various improvements over the years, including a 2015 kitchen remodel, water heater installation, and electrical upgrades.

The property's maintenance history reveals recurring issues with water damage, weatherproofing, and safety systems. Notable complaints include 2019 reports of bathroom conditions, rodent infestation, and window issues, along with 2021 concerns about ceiling leaks and mold. Historical records show the installation of an automatic fire sprinkler system in 1990 and more recent fire alarm system concerns in 2021, which were reportedly corrected in early 2022. The building's recent permit activity includes electrical improvements (2023) and various maintenance work, though multiple permits from 2013-2015 were either cancelled or expired. While the property has maintained basic safety systems, including smoke detectors and sprinklers, the pattern of recent complaints suggests ongoing challenges with building maintenance and compliance with current codes and regulations.

Risk rating

How 410-412 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.
