Initial analysis

The Leung Family Trust owns this two-unit residential building located at 1717-1719 9th Avenue in San Francisco's Inner Sunset neighborhood. Built in 1924, this duplex underwent significant renovations between 2008-2010, converting what was originally a single-family home into a multi-unit dwelling. The transformation included a horizontal extension to the rear of the building on both first and second floors, with the first floor becoming an additional unit containing one bedroom, a study, kitchen, and bathroom. The second floor was remodeled to include two bedrooms, a study, kitchen, and two bathrooms. The conversion also involved upgrading the parking facilities from one car to accommodate two compact vehicles. During this renovation period, comprehensive upgrades were performed, including the installation of two new furnace units, complete plumbing work for three bathrooms, two kitchens, laundry facilities, electrical system overhauls including new wiring and panels, and the installation of numerous modern amenities such as eight smoke detectors, a hydro massage tub, and various kitchen appliances.

The building's recent history (2020-2024) indicates recurring issues with parking violations, particularly sidewalk parking, with multiple citations issued for vehicles blocking sidewalks near the property. There was also one instance of a driveway blocking violation in October 2023 that resulted in a citation. The only infrastructure maintenance issue recorded was a streetlight outage in June 2014, which was promptly resolved with the installation of a new 100W lamp. All building permits from 2008-2010 are marked as complete, showing successful execution of the major renovation work that transformed the property into its current configuration.

Risk rating

How 1717-1719 9Th 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 1493 buildings in this neighborhood, 15 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.

Neighborhood location

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

12-Month severity forecast
No violation 87.5%
Moderate concern 10.1%
Severe concern 2.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
