Initial analysis

The two-unit residential building at 1503-1505 25th Avenue in San Francisco's Central Sunset neighborhood is a two-story flats and duplex structure built in 1939, currently owned by Victor Hong Shan So. The property has experienced several infrastructure challenges in recent years, with the most notable being two significant sewer-related incidents in early 2024: flooding on the property at the end of January and a sewage back-up discharge from a side sewer vent on Christmas Eve, both of which required intervention from PUC Sewer Operations and were marked as resolved. The building's maintenance history includes at least one documented repair attempt, with a permit issued in 1996 for stucco repair work on the front bay window area, though this permit has since expired.

The property has been subject to numerous municipal service calls between 2022 and 2024, with recurring issues related to street and sidewalk cleanliness. This includes multiple reports of abandoned mattresses (September and November 2024), loose garbage (November 2024), and an incident of human waste or urine (August 2024). The building's immediate vicinity has also faced parking enforcement challenges, with three documented incidents of illegal parking between March 2023 and March 2024, resulting in citations for vehicles blocking driveways or parking on sidewalks. The property has maintained compliance with service resolutions, as all reported issues have been officially closed, though many of these incidents suggest ongoing environmental and infrastructural concerns in the immediate area.

Risk rating

How 1503-1505 25Th 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
