Initial analysis

The property at 1501-1503 24th Avenue is a two-unit, two-story multi-family residential building located in the Central Sunset neighborhood, built in 1939 and owned by Simon Lau and Lisa Chiu. The building's permit history shows significant maintenance and improvement work carried out from 1989 through 2019, including major structural work such as dry rot repair of exterior walls in 1991, wood header replacement, and the installation of a bay window. Earlier improvements included kitchen renovations in 1990, a vertical addition, and window upgrades in 1989. A street space permit was issued in 2019, and there is an open complaint from July 2019 regarding waterproofing, painting, and landscaping issues.

The property has experienced several infrastructure and maintenance challenges in the surrounding area, with multiple 311 calls recorded between 2024 and 2023. Recent issues include illegal parking incidents, sidewalk blockage by construction equipment, and various garbage and debris problems on the street and sidewalk. Notably, there was one flood-related incident reported in December 2024, though it appeared to be street-related and required no further attention. The building's complaint history shows past concerns about over-occupancy in 2009, but this complaint is no longer active. While the property has undergone significant improvements over the years, the recent pattern of municipal service calls in the vicinity suggests ongoing challenges with street maintenance and parking issues, though these are primarily external to the building itself.

Risk rating

How 1501-1503 24Th 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.
