Initial analysis

The two-unit residential building at 1214-1216 23rd Avenue in San Francisco's Central Sunset neighborhood has undergone several significant changes since its construction in 1923. Most recently, in early 2024, the property faced multiple building violations related to lead paint hazards, including issues with peeling paint and non-compliance with San Francisco lead ordinance regulations. These violations were officially abated by May 2024. The building's renovation history includes significant work completed in 2003, when $28,000 was spent to create study rooms and bathrooms on the ground floor of both units, with corresponding electrical upgrades including additional receptacles, light outlets, smoke detectors, and switches. Earlier improvements involved the replacement of aluminum windows in the sunroom in 1993.

The property has experienced various maintenance and infrastructure issues over the years, including concerns about illegal units reported in 2004 (resolved in 2012), sidewalk defects in 2017 and 2019 (though no hazardous conditions were found), and a sewage backup incident in 2019. More recent service requests have included general maintenance matters such as a paint shop service request in 2024 and a Christmas tree removal in early 2023. Historical permit records show earlier work including sidewalk modifications and various maintenance items, though some permits from the 2000s have an unusual duplicate entry. The current ownership is listed as Michelle Quang Ngan & Denni, and the building is classified as a Flats & Duplex structure with two stories.

Risk rating

How 1214-1216 23Rd 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.
