Minnesota Contractor License & Trade Guide
Minnesota centralizes much of residential and skilled-trade licensing through the Department of Labor and Industry (DLI). The supplied source identifies company prefixes BC · CR · RR, electrical credentials such as EM · EJ, plumbing credentials PM · PJ, and the MB mechanical contractor bond. It also makes two routing distinctions clear: Q registrations belong to qualifying people, not the contractor company, and asbestos/lead credentials run through the Minnesota Department of Health.

01 · Licensing model
How Minnesota Actually Licenses Contractors
Minnesota combines statewide residential company licensing, statewide electrical and plumbing credentials, a mechanical bond system, qualifying-person registrations and separate MDH environmental credentials.
DLI handles the core construction lanes; MDH and local AHJs fill the gaps.
The supplied source identifies BC Residential Building Contractor, CR Residential Remodeler and RR Residential Roofer as company credentials. Electrical and plumbing use separate individual credential ladders. HVAC/mechanical is different: Minnesota uses the MB mechanical contractor bond rather than a statewide competency license.
Critical routing rule: a QB, QC, QR or QI number is a qualifying-person registration, not the company contractor license. Commercial general contracting has no universal statewide license in the source, and local requirements remain important for HVAC and other out-of-scope work.

Minnesota Trade Routing Guide
Twelve practical guides connect Minnesota credentials and local routing rules to the permit categories where contractors, trades and suppliers can identify project activity.
BCPRIORITY TRADE 01Residential Building / New Construction+
Licensing / qualification
Statewide residential building contractor licensing is through DLI. Verify the company license and qualifying person before routing residential construction opportunities.
Routing note
BC is the company credential.
Opportunity fit
Use for new one- to four-family residential construction and broad residential building scopes.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
CRPRIORITY TRADE 02Residential Remodeling+
Licensing / qualification
CR is the company license for residential remodeling. It is distinct from BC and from the qualifying person registration.
Routing note
Verify the company license, not only a Q registration.
Opportunity fit
Strong lead categories include additions, kitchens, baths, structural remodels and whole-home renovations.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
RRPRIORITY TRADE 03Residential Roofing+
Licensing / qualification
Residential roofing is separately licensed statewide through DLI under the RR prefix.
Routing note
Confirm active RR status before routing roofing work.
Opportunity fit
Useful for reroof, storm restoration and roof replacement permit signals.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
EM/EJPRIORITY TRADE 04Electrical+
Licensing / qualification
Minnesota uses statewide DLI electrical credentials, including master and journeyworker levels.
Routing note
Electrical contractors also operate under DLI business licensing/registration requirements.
Opportunity fit
Route panel, service, new wiring, solar electrical and major electrical alteration opportunities to properly credentialed firms.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
PM/PJPRIORITY TRADE 05Plumbing+

Routing note
Verify active plumbing credentials and contractor status where required.
Opportunity fit
Strong signals include water heater, repipe, addition, bath, commercial TI and new construction permits.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
MBPRIORITY TRADE 06HVAC / Mechanical+
Licensing / qualification
Minnesota is unusual: there is no statewide HVAC competency license. A mechanical contractor bond is the core statewide DLI requirement for covered mechanical contracting.
Routing note
MB is a bond record, not a competency license.
Opportunity fit
Local licensing can still matter, so verify the city where the project sits.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
MIPRIORITY TRADE 07Manufactured Home Installation+
Licensing / qualification
Minnesota DLI separately regulates manufactured-home installers.
Routing note
MI is the source-designated manufactured-home installer prefix.
Opportunity fit
Use for setup, replacement, manufactured housing communities and installer verification.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
ASBPRIORITY TRADE 08Asbestos+
Licensing / qualification
Minnesota Department of Health, not DLI, regulates asbestos contractor and individual credentials.

Separate agency and credential system.
Opportunity fit
Relevant to demolition, renovation, school, commercial and pre-renovation environmental work.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
LEADPRIORITY TRADE 09Lead+
Licensing / qualification
MDH separately regulates lead firms and individual lead disciplines.
Routing note
Do not treat this as a DLI two-letter contractor prefix.
Opportunity fit
Relevant to pre-1978 renovation, paint disturbance, window replacement and abatement work.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
QB/QC/QR/QIPRIORITY TRADE 10Qualifying Person Registrations+
Licensing / qualification
Q registrations belong to the qualifying person and are not the company contractor license.
Routing note
Never gate a company solely on a Q number.
Opportunity fit
Match the qualifying person to the active BC, CR, RR or MI company credential.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
LOCALPRIORITY TRADE 11Commercial General Contracting+
Licensing / qualification
Minnesota has no statewide commercial general contractor license.
Routing note
Commercial GC requirements can be local or project-specific.
Opportunity fit
Verify the local building department, owner requirements and permit rules.
TigerLeads use
Use permit and project data as an early signal, then verify the contractor credential, jurisdiction and commercial availability before outreach.
LOCAL-HVACPRIORITY TRADE 12Local HVAC Licensing+
Licensing / qualification
Because HVAC is not competency-licensed statewide, local mechanical/HVAC requirements can be especially important.

06 · Verification workflow
Verify Minnesota in the Right Order
Minnesota can be misread when company licenses, Q registrations, individual trade credentials and the mechanical bond are treated as interchangeable. Keep each record in its proper lane.
01
Identify the project jurisdiction
Determine the city or local building department so local commercial, mechanical and permit requirements are not missed.
02
Read the permit scope
Determine whether the work is residential building, remodeling, roofing, electrical, plumbing, HVAC/mechanical or environmental.
03
Verify the company credential
For BC, CR, RR and MI lanes, verify the contractor company record rather than relying on the qualifying person alone.
04
Match the Q registration
QB, QC, QR and QI identify the qualifying person. Use them as supporting qualification records, not substitutes for the company license.
05
Use the correct agency
DLI handles core construction credentials and the MB mechanical bond. MDH handles asbestos and lead credentials.
06
Re-check live rules
Local licensing, exemptions, permits, insurance, bonds and credential status can change. Use the current issuing authority before operational reliance.
07 · Official verification

Minnesota Contractor Licensing Questions
Common questions about Minnesota DLI company licenses, skilled-trade credentials, Q registrations, HVAC bonding, MDH environmental credentials and permit-based opportunity routing.
01Does Minnesota require a contractor license?+
Yes for covered residential contracting. DLI licenses residential building contractors, remodelers and roofers statewide. Commercial general contracting does not have one universal statewide GC license.
02What do BC, CR and RR mean?+
BC is Residential Building Contractor, CR is Residential Remodeler and RR is Residential Roofer. These are company-level DLI credentials.
03What is a Q registration?+
QB, QC, QR and QI identify qualifying-person registrations. They are not substitutes for the company license.
04Does Minnesota license HVAC contractors?+
Not with a statewide competency license. The source identifies a $25,000 mechanical contractor bond requirement through DLI, while local HVAC licensing can still apply.
05What does MB mean?+
MB is the source-designated mechanical contractor bond record. Treat it as a bond/registration lane rather than a trade competency license.
06Who licenses electricians?+
Minnesota DLI regulates electrical licensing statewide, including master and journeyworker electrician credentials.
07Who licenses plumbers?+
Minnesota DLI regulates plumbing statewide, including master and journeyworker plumber credentials.
08Does Minnesota have a statewide commercial GC license?+
No universal statewide commercial general contractor license is identified in the source. Commercial work can still be subject to local permits, registrations and project requirements.
09Who regulates asbestos?+
The Minnesota Department of Health regulates asbestos contractor and individual credentials separately from DLI.
10Who regulates lead work?+
MDH separately regulates lead firms and individual lead disciplines.
11How should TigerLeads treat a Q number?+
As supporting qualifier information only. Company eligibility should be tied to the active company credential, not solely the qualifying-person registration.
12Can a permit be treated as an open bid?+
No. A permit is a project signal. It can indicate that work is planned or underway, but it does not prove that a subcontract or purchase is still unawarded.
13Where should HVAC firms be verified?+
Check the DLI mechanical bond and then the local jurisdiction for any city-specific mechanical or HVAC licensing.
14Are local licenses pre-empted for state-licensed residential work?+
The source notes state licensing pre-empts local licensing for covered work, while local rules remain relevant for exemption holders, HVAC and out-of-scope/commercial work.
15What is the best way to verify a Minnesota contractor?+
Start with the DLI license lookup for DLI-regulated credentials and MDH for asbestos/lead, then verify local requirements for work outside statewide licensing.
16Why do prefixes matter for data routing?+
The prefix can identify the credential type quickly, helping normalize contractor records before active-status verification.
17Does a company license replace individual trade credentials?+
No. Electrical and plumbing work can involve both company/business requirements and properly credentialed individuals.
18What should contractors do before accepting a lead?+
Confirm scope, jurisdiction, permit stage, licensing, bond/insurance requirements and whether the opportunity is still commercially available.
Minnesota opportunity intelligence
Find the project. Route the right trade.
TigerLeads turns permit activity into early construction opportunity intelligence. Use Minnesota licensing and routing data to qualify who can pursue the work, then confirm whether the project is still commercially available.
