Rochester, MN Contractor List With Phone Numbers (2026)

Rochester, Minnesota — the Mayo Clinic metro — runs one of the most contactable permit feeds of any mid-size city we track. In the last 30 days alone, PermitGrab indexed 1,375 building permits, newest dated June 20, 2026, and from that activity built 205 named contractor businesses with 252 distinct, deduplicated phone numbers. That is unusually high phone coverage — the Rochester source publishes contact information on most permit rows, so nearly every named contractor comes with a dial-ready number.

The figure that matters for outreach is 252 distinct contractor phone numbers, deduplicated so one busy electrician is one number, not the handful of permits they filed. For a city this size, that is a dense, current, dial-ready list rather than a thin sample.

Where the Work Is

The trade mix is broad-based residential and infrastructure: General Construction leads with 145 distinct businesses, followed by Electrical (63), Plumbing (40), Windows & Doors (23), HVAC (22), and Additions (20). The strong electrical and plumbing presence alongside GC reflects the Mayo-driven construction and steady housing demand around the medical campus.

Who This Helps

Building-material suppliers reach 145 general contractors. Electrical and plumbing wholesalers reach the two largest mechanical pools at 63 and 40 shops. Window, door, and HVAC suppliers get clear retrofit segments. And software, insurance, and fleet vendors reach a tight list of small businesses demonstrably active this month, almost all with a phone attached.

Freshness Is the Point

This list refreshes as the City of Rochester publishes — newest record days old, 1,375 permits in the last month. See the live feed on the Rochester permits page, and see PermitGrab pricing for the full named list with phones delivered daily.
