Initial analysis

The three-story, two-unit multi-family residential building at 2374 21st Avenue in San Francisco's Parkside neighborhood, owned by Tan Julie Lee & Tian Kin, was constructed in 1985. The building's documented history shows several significant renovation activities, most notably in late 2015 when a major renovation project was undertaken costing $5,000, which included bathroom cabinets, tiling, lighting upgrades, kitchen improvements, flooring refinishing, and window replacements at the rear of both units. This renovation was somewhat controversial, as it followed a tenant complaint filed in October 2015 regarding unauthorized remodeling work in the upper unit, involving hammering, drilling, and the presence of multiple dumpsters, though this complaint was later marked as not active.

The building's earlier history shows typical development progression, with permits issued in 1983 for its construction. The property has experienced a minimal number of neighborhood issues, with only two reported incidents of graffiti in the surrounding area - one in 2020 involving a pole and another in 2017 that was determined to be offensive. Both graffiti incidents were resolved through normal municipal processes. The most recent building permit activity from 2015 represents the last major documented improvement to the property, with no subsequent building complaints or permits on record through October 2023.

Risk rating

How 2374 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
89th percentile

Out of 255 buildings in this neighborhood, 28 are predicted to be safer.
