Initial analysis

The two-unit residential building at 1494-1496 28th Avenue in San Francisco's Central Sunset neighborhood, owned by the Yvonne Ng Trust, is a two-story flats and duplex structure built in 1939. The building's history includes several significant improvements and events, beginning with substantial additions in 1984 when a family room, bedroom, and bathroom were added. In 1989, repairs were made to address earthquake damage, specifically to the front stucco. A notable complaint was filed in 2009 regarding unpermitted remodeling of the downstairs unit, though this issue was quickly addressed within two weeks. More recent records from 2023-2024 show multiple municipal service interactions, primarily related to street cleaning and parking enforcement issues, including two citations for sidewalk parking violations in April and May 2024. The most recent building-related activity was a construction noise complaint in October 2023, which was transferred to the appropriate department for tracking. The property has also seen regular municipal services for waste management, including multiple reports of debris and garbage issues that were resolved, and seasonal services like Christmas tree removal in January 2023. Two street space permits were issued, one in 2017 and another in 2007, though their specific purpose remains general in nature.

Risk rating

How 1494-1496 28Th 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
50th percentile

Out of 814 buildings in this neighborhood, 407 are predicted to be safer.
