Initial analysis

The two-unit residential building at 101 17th Avenue, constructed in 1911, has experienced several significant events throughout its history, with the most recent building permit issued in 2018 for a street space permit. The property faced multiple violations in 2003, when unauthorized construction work was identified, including garage modifications, security gate installations, window replacements, and kitchen renovations. These violations led to abatement proceedings, which were ultimately resolved by 2013. The building has undergone several proper maintenance works, including two roofing projects in 2004 (cost: $16,000) and 2006 (cost: $6,720), and various fence-related improvements in the early 2000s.

Recent records show two fire-related complaints in February 2017 regarding illegal occupancy and blocked exits, though both were marked as having "No Jurisdiction." The property has experienced three false alarms or false calls related to fire detection systems, and one minor contained cooking fire incident, with no civilian injuries reported in any of these incidents. The most recent building complaint was filed in November 2024, though the details are minimal and the status is marked as "Not Active." Current issues include a potentially hazardous situation involving exposed hot and cold plumbing pipes reported in February 2003 and some reports of sidewalk defects, parking violations, and street cleaning matters in the vicinity, as evidenced by recent 311 calls throughout 2024.

Risk rating

How 101 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
51th percentile

Out of 660 buildings in this neighborhood, 323 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 78.0%
Moderate concern 17.7%
Severe concern 4.3%
