What permits do you need to open a contractor or trade in Rochester?

There is no single figure, and any site quoting one is rounding away the part that matters. Of the 10 records listed for a contractor or trade in Rochester, MN, 1 apply to every business of this type and 9 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.

3 of the 10 are charged as a range or a formula set by the issuing agency, and 3 have no fee published at all. The ones that vary:

Commercial Building Permit: Valuation-based: $25.00 ($1–$500); $25 + $2.00 per additional $100 ($501–$2,000); $55 + $9.00/$1,000 ($2,001–$25,000); $262 + $6.50/$1,000 ($25,001–$50,000); $424.50 + $4.50/$1,000 ($50,001–$100,000); $649.50 + $3.50/$1,000 ($100,001–$500,000); $2,049.50 + $3.00/$1,000 ($500,001–$1,000,000); $3,549.50 + $2.00/$1,000 above $1,000,000. Plan review is 65% of the building permit fee. Trade permits carry a separate $25 application fee plus a $90 administrative fee, on top of their own valuation scale. Working without a permit draws a penalty of $100 (1st), $150 (2nd), or $200 (3rd occurrence).

Trade Contractor Licences: Heating (HVAC) Contractor $125; Master Installer $60; Sewers & Drains $90; Sidewalks – Cement $90; Sidewalks – Asphalt $90; Sign – Erect & Maintain $90; Tree Trimmer $90.

Residential Building Contractor or Remodeler Licence: $500–$700 for two years, banded by gross annual receipts, including the recovery fund contribution

Permits for a contractor or trade in Rochester, MN come from 4 separate offices: City of Rochester Building Safety Division, City of Rochester City Clerk, Office of the Minnesota Secretary of State, Business Services Division, Minnesota Department of Labor and Industry, Construction Codes and Licensing Division. No single office issues them all, which is why an opening means filing in several places rather than one.

Quoted directly from the city's own page: 'Electrical, Plumbing, HVAC (State), Residential Building: Licensed through Minnesota Department of Labor & Industry.' No separate city-issued general contractor licence or bond requirement was found.

There is no fee because there is no such licence. Quoted directly: 'There is no general business license required by the City of Rochester. Only certain specific types of businesses are required to obtain a license from the City.' Confirmed city-specific licence categories with 2026 fees: Massage Therapist $112 (+$150 investigation fee), Massage Therapy Business $220 (+$250 investigation fee), Pawnbrokers $750, Sidewalk Cafés/Parklets $300 (2-year term), Vending Cart $375.

Post is the cheap channel in Minnesota, which is the reverse of almost everywhere else. The extra twenty dollars online or over the counter is an expedited-service premium, not a convenience charge: the Secretary of State processes mail on an ordinary first-come queue and treats online and in-person filings as expedited, typically two to five business days. A corporation costs the same $135, a nonprofit $70. The recurring obligation is free but real — see the annual renewal.

The same $135 as an LLC, with no share-based component, so Minnesota gives no filing-cost reason to prefer either structure — and the annual renewal is free for both. The same twenty-dollar expedited premium applies online or in person. A foreign corporation pays considerably more to qualify, at $200 by post.

No fee at all for a domestic LLC, corporation, nonprofit, cooperative or limited partnership, on any filing channel — but it is compulsory, and free does not mean optional. Miss it and a corporation is administratively dissolved and an LLC administratively terminated at the end of that calendar year, with a foreign entity's authority revoked. The saving grace is that reinstatement is retroactive: it restores the entity as of the dissolution date and validates contracts entered in the meantime. An entity inactive more than six years cannot be reinstated online at all. Foreign corporations and limited liability partnerships do pay, at $115 and $135 by post.

No fee, because Minnesota issues no general business licence — and its own start-up guide makes the point by where it uses the phrase. The guide describes state licensure entirely in terms of specific activities, trades and professions, and reserves the words general business licence for the local tier, noting that some local governments require one involving no more than registration and payment of a fee. The state's directory of licences is organised by regulated activity with no omnibus entry. Minneapolis and St Paul both run licensing departments, so a city licence is a real possibility even though a state one is not.

Minnesota requires no surety bond of a residential contractor, which is unusual — instead the licence fee itself funds a contractor recovery fund, and the contribution is banded by turnover: $320 under a million dollars of gross receipts, $420 to five million and $520 above, on top of a $180 base. The fund compensates homeowners up to $100,000 a claim and $550,000 against any one licensee. Insurance is still required, at $100,000 per occurrence and $300,000 aggregate. The licence is needed by anyone contracting directly with an owner of one to four residential units across more than one of eight skill areas, anyone building for resale, and anyone doing roofing at all. Under fifteen thousand dollars of residential receipts you can hold a certificate of exemption for ten dollars instead. Since July 2023 residential solar installers need this licence too, expressly so homeowners can reach the recovery fund. Every licence needs a qualifying person who passes an exam and does fourteen hours of continuing education per cycle, and the licence cannot be renewed if that person's registration has lapsed.

A $25,000 surety bond is required here where the residential builder licence needs none, along with $100,000 of liability cover per occurrence. The company must designate a responsible licensed individual holding an active master electrician licence, who has to be an owner, officer, member or salaried employee actively engaged in the company's electrical work, and who cannot serve as the responsible individual for any other contractor. A licensed electrician may supervise no more than two unlicensed employees. Plumbing contractors pay the same $188 but on a different clock, expiring on 31 December of odd-numbered years, and carry their own $25,000 bond.

This is the one people get wrong. Minnesota licenses electricians and plumbers but issues no state licence for mechanical or HVAC contractors at all — and yet an HVAC business still cannot lawfully contract for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work without filing a $25,000 bond with the department, at a hundred dollars for two years. The department says so plainly and adds that mechanical contractors must also comply with local licensing requirements. Individual HVAC workers likewise need no state licence, but cities may require a competency card the department neither issues nor tracks. So the practical position is a state bond filing on top of a patchwork of city rules.
