Initial analysis

The two-unit, two-story multi-family residential building at 171 7th Avenue, located in the Lake-Presidio neighborhood, has a history dating back to 1908. The property has undergone several maintenance and improvement projects over the years, with the most significant recent work being the replacement of seven front windows with wood windows in 2015 at a cost of $8,500. Infrastructure maintenance is documented with repairs to rear stairs in 1990 addressing dry rot issues, though an attempt to repair the rear wall siding in 1987 and a permit from 1983 were either expired or cancelled.

The building's recent history has been marked by multiple parking enforcement issues between 2019 and 2021, with several documented cases of vehicles parking on sidewalks, blocking driveways, and double parking in the vicinity. While most of these incidents were resolved through citations or officer intervention, there appears to be an ongoing challenge with parking compliance in the area. Notably, there were two incidents of human or animal waste on the street reported in April 2023, which were resolved through Department of Public Works intervention. The property has also required three street space permits (2008, 2016) in recent years, though these were minor in cost ($1 each).

Risk rating

How 171 7Th 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, 191 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.

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

Building age

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

12-Month severity forecast
No violation 83.8%
Moderate concern 12.3%
Severe concern 3.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
