Initial analysis

The Lai/ng Family Trust owns this two-unit residential building located at 1486-1488 17th Ave in San Francisco's Inner Sunset neighborhood. This two-story flats and duplex structure, built in 1946, has undergone several significant renovations and maintenance work over the past few decades. Most recently, in 2018, the building underwent reroofing work costing $11,600, though this permit has since expired. A gas houseline extension project was completed in 2012, which involved extending the two separate houselines serving units 1486 and 1488.

Looking further back, the building received some exterior improvements in 2001 with the installation of vinyl siding on the right side of the house, though this area is not visible from the street. Two major repairs were completed in 1995, including reroofing work and repairs to the front walls, stucco, and sheathing, which had suffered damage from pests. The building's maintenance history shows a pattern of regular upkeep, particularly regarding roofing structures and exterior elements, though several of the older permits from the 1990s and 2001 are listed as expired rather than completed.

Risk rating

How 1486-1488 17Th 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.
