Initial analysis

171 17th Avenue is a two-unit, two-story multi-family residential building located in the Lake -- The Presidio neighborhood, owned by Gateway Equity LLC and built in 1914. The property has encountered several noteworthy issues in recent years, with the most concerning being an active building complaint filed in May 2019 regarding an alleged illegal unit and property maintenance violations. More recent developments from November 2024 include two environmental health-related complaints about infestation and inadequate building exterior maintenance, both of which were transferred to the San Francisco Department of Public Health's Healthy Housing Program. The building's maintenance history shows minimal documented improvements, with only one known permit from 1995 for reroofing work that has since expired.

The property has experienced multiple parking-related incidents between September and October 2021, with several cases of driveway blocking documented, resulting in some citations being issued. There were also reports of illegal parking in August 2021, and the building's immediate vicinity faced park proximity challenges, with adjacent encampment cleanup required in October 2021. Additionally, a malfunctioning smoke detector activation was recorded at the property, though no civilian injuries were reported. While the building has survived through a century of urban development, the recent pattern of complaints and violations suggests ongoing maintenance and management challenges that may impact resident quality of life.

Risk rating

How 171 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 660 buildings in this neighborhood, 343 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.

Construction spend, owner's portfolio

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 78.8%
Moderate concern 17.5%
Severe concern 3.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
