Initial analysis

This two-unit residential building, located at 2414-2416 43rd Avenue in San Francisco's Outer Parkside neighborhood, was constructed in 1946 and is currently owned by Jian Calvin Biao. The property has undergone several significant modifications and improvements over the past few years, most notably the legalization of a ground-floor dwelling unit in 2019 which included 523 square feet of living space comprising a living/dining area, kitchen, bedroom, and bathroom. This project, which cost approximately $60,000, also required the installation of a fire sprinkler system. The building has seen recent infrastructure improvements including a complete reroofing project in December 2024 (cost: $8,800) and a main service conduit inspection in December 2023, indicating ongoing maintenance of essential systems.

The property has experienced some maintenance and compliance challenges, with multiple permits from 2022 for plumbing and electrical work related to a ground floor kitchen and bathroom installation, though these permits are now listed as expired. The street surrounding the property has been the subject of various municipal service calls in 2024, including reports of garbage and debris, abandoned vehicles, and an overgrown tree requiring maintenance. While many of these street-related issues have been resolved by city services, there are currently three open cases from late 2024 regarding illegal postings and a tree maintenance request. The property's parking facilities underwent notable change as part of the unit legalization process, with the garage door being removed and the opening converted to include a residential wooden door and a double-hung window, though some concerns about parking availability may have emerged from this modification.

Risk rating

How 2414-2416 43Rd 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.
