Initial analysis

The property at 515-517 14th Avenue is a two-unit, two-story multi-family residential building located in the Central Richmond neighborhood. Built in 1923 and owned by Yuan Allen G L & Jiang Paul, the building underwent several significant changes and faced multiple violations in 2001. The most concerning issue during that time was the illegal conversion of a garage space into a two-room apartment, creating an unauthorized third dwelling unit in the building. This unauthorized unit reportedly lacked proper fire safety measures, including fire-rated construction, two exits, automatic fire sprinklers, and smoke detectors, as well as legal heat and adequate light and ventilation. Additionally, there were multiple health and safety concerns related to lead paint hazards, plumbing and electrical violations, and egress obstructions. All these violations were officially abated by June 12, 2002.

The building has had two documented permitted improvements: in 2001, a conversion project was completed to remove a sink and stove to create a laundry area, playroom, and storage room (valued at $7,000), and in 1986, non-structural work was performed to replace bathtubs, toilets, and cabinets. More recently, in recent 311 calls from 2020 to 2024, there have been various requests for street and sidewalk cleaning, including reports of garbage, debris, and waste issues in the surrounding area. These external maintenance issues were generally resolved by the Parks Department or Public Works, with the most recent complaint dating to December 2024 regarding garbage and debris.

Risk rating

How 515-517 14Th 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
