Initial analysis

The two-unit residential building at 25 Grafton Avenue, owned by Yee Ming, was constructed in 1923 in the Ingleside neighborhood, and has experienced several significant events over its history, with particular attention needed to recent developments. Most notably, in March 2021, a permit was filed for substantial modifications including the demolition of three storage sheds and construction of a two-story accessory dwelling unit in the rear yard, representing a significant investment of $160,000. The building has undergone various maintenance issues over the years, including a 1999 complaint about mold and improper ventilation in the bathroom and kitchen, though this was resolved by December 1999. A plumbing-related violation occurred in 2003 regarding unpermitted work, which was quickly abated within a week.

The property has experienced recurring issues with parking violations in recent months, with multiple 311 calls between November 2024 and January 2025 regarding sidewalk parking. Six of these resulted in citations being issued, suggesting an ongoing parking enforcement challenge in the immediate vicinity, though several requests were either unable to be validated or officers could not locate the offending vehicle. Additionally, there are records of five fire-related complaints between 2008 and 2017, most of which were determined to have no merit or were otherwise resolved, though there were two violations issued in March 2008 regarding hazardous materials making exits unsafe and locked exit doors requiring special effort to open. The building's most recent known complaint concerns a parking issue from January 2025, representing the most current documented concern related to the property.

Risk rating

How 25 Grafton 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.
