Initial analysis

The property at 247 17th Avenue in the Central Richmond district is a two-unit, two-story multi-family residential building constructed in 1911, currently owned by Michael A. Su. The building underwent significant changes when a major renovation project was proposed in 2015, which included horizontal and vertical additions with extensive interior modifications, though this particular permit was ultimately cancelled. Earlier building history shows the structure experienced fire damage in 1991 requiring repairs, and there were attempts in 1989 to demolish the existing single-family dwelling and construct a two-family dwelling, though those permits were cancelled.

Recent incidents at the property have primarily involved parking-related complaints, with multiple reports of vehicles parking on sidewalks and blocking driveways throughout 2023 and 2024, leading to several citations being issued. The most concerning recent issue was a sewage back-up incident from the side sewer vent in November 2024, which was resolved by field personnel. The building's history includes a reroof project from 1996, though this permit has expired. Planning records from the property indicate various proposals over the years, including a major alteration project that aimed to convert the existing structure into a two-unit building with modern amenities, parking spaces, and bicycle storage, though the extent of these improvements as suggested in the permits is not entirely clear in the current building's status.

Risk rating

How 247 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.

Neighborhood percentile

Out of 2250 buildings in this neighborhood, 1012 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 76.1%
Moderate concern 19.3%
Severe concern 4.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
