- MN-REMOD is the qualifying remodeler (QC) exam tied to Minnesota's residential remodeler (CR) business license.
- The exam has 110 multiple-choice questions in 330 minutes with a 70% minimum passing score.
- Roughly 60% of questions cover the 2020 Minnesota Residential Code; the rest cover statutes and rules.
- Passing gives you QC registration only - the business still needs its own CR license, insurance, and workers comp.
What Is MN-REMOD Certification?
MN-REMOD refers to the Minnesota Residential Remodeler License Exam - the qualifying remodeler examination, commonly labeled "QC" in state paperwork, that a business must pass in order to hold a residential remodeler (CR) business license. It is administered directly by the Minnesota Department of Labor and Industry (DLI), Construction Codes and Licensing Division, which both governs and delivers the exam. There is no third-party testing vendor and no separate certifying association involved.
It's important to understand what this exam is not. The QC exam is distinct from the qualifying builder examination that supports the residential building contractor (CBR) license. A remodeler who passes QC and holds an active CR license can legally perform work on existing residential structures - additions, remodels, repairs - but the CR license does not authorize new home construction or building a detached garage from the ground up. If your work touches only existing structures, QC is the exam you want. If you're unsure which exam path fits your business plans, the MN-REMOD requirements guide breaks down eligibility for both tracks.
Who Administers the Exam
Because DLI both writes the rules and runs the test, there's no ambiguity about where to look for authoritative information - everything flows from DLI's Construction Codes and Licensing Division. DLI supplies the reference materials used during testing, sets the fee structure, and manages the renewal cycle for qualifying-person registrations. This centralization also means the exam content maps directly and predictably to the state's own code adoption and reference manual, rather than to a generalized national body of knowledge.
No prerequisite education or documented work experience is required just to sit for the exam. However, to actually use a passing score, the person taking the test must have an eligible ownership, officer, or managing-employee relationship to the remodeling business that will hold the CR license - you can't pass QC on behalf of a company you have no formal tie to.
Exam Format and Question Style
The MN-REMOD (QC) exam consists of 110 multiple-choice questions administered over 330 minutes, with a minimum passing score of 70%. Every question carries equal point value - there's no partial credit for near-misses, and no weighting that makes any single question worth more than another. That flat scoring structure is one of the mechanical details covered in more depth in the MN-REMOD passing score breakdown.
Question format is more varied than a simple "pick one of four" test:
- Each question offers five answer options, not the more common four.
- Some questions require selecting more than one correct answer.
- Some questions ask you to identify the incorrect statement among the choices - meaning you must evaluate every option rather than stop at the first plausible answer.
This format rewards careful reading over quick pattern-matching. Candidates who skim answer choices looking for a familiar phrase tend to get tripped up on the "which statement is false" style questions specifically because the correct answer is the outlier, not the best-sounding option.
Key Takeaway
Read every one of the five options on each question before answering - the exam intentionally uses negatively worded and multi-select questions that punish quick guessing.
The Ten MN-REMOD Exam Domains
DLI organizes the QC exam's technical content around ten official domains. Roughly 60% of the total exam draws from residential-code material tied to these domains, with the remainder covering business statutes and rules that apply to licensed remodelers. For a full breakdown of how each domain is weighted and tested, see the complete guide to all 10 content areas.
Domain 1: Plans and Specifications
Covers reading and interpreting construction documents accurately enough to identify code compliance issues before work begins.
- Symbol and notation interpretation on residential drawings
Domain 2: Energy Code (Envelope Criteria)
Focuses on insulation, air sealing, and envelope performance requirements under the current energy code adopted by Minnesota.
- Minimum R-values and envelope assembly requirements for remodeled spaces
Domain 3: Building Planning/Life Safety
Addresses egress, fire separation, and other life-safety provisions that apply when altering existing residential structures.
- Egress window and emergency escape requirements in remodeled bedrooms
Domain 4: Sitework
Covers grading, drainage, and site preparation considerations relevant to remodeling and additions.
- Site drainage requirements around foundations during additions
Domain 5: Concrete & Masonry Footings and Foundations
Tests foundational construction knowledge as it applies to additions and structural remodel work.
- Footing depth and foundation wall requirements for additions
Domain 6: Carpentry
Covers framing methods, structural connections, and wood construction requirements under the 2020 Minnesota Residential Code.
- Header sizing and load-bearing wall modifications common in remodels
Domain 7: Roofing
Addresses roofing materials, flashing, and installation requirements for reroofing and roof-related remodel work.
- Flashing details at roof-to-wall intersections
Domain 8: Exterior Finishes
Covers siding, cladding, and weather-resistive barrier requirements for exterior remodel projects.
- Water-resistive barrier and siding attachment requirements
Domain 9: Foam Plastic Insulation
Focuses on code requirements specific to foam plastic insulation products, including thermal barrier and ignition barrier rules.
- Thermal barrier requirements when foam insulation is exposed
Domain 10: Interior Finishes
Covers interior wall, ceiling, and finish material requirements relevant to remodeling projects.
- Fire-rated assembly requirements for interior finish materials
Beyond these ten technical domains, expect a meaningful portion of the exam to test Minnesota business statutes and rules governing licensed remodelers - contract requirements, licensing obligations, and related regulatory content that doesn't fit neatly into a code chapter.
What Happens on Exam Day
The QC exam is administered in person, and DLI supplies the core reference materials you're allowed to use during the test:
- The 2020 Minnesota Residential Code
- The DLI Reference Manual for Residential Building Contractor and Remodeler License Exam
- A standard desktop calculator
Personal reference books, handwritten notes, tabs with commentary, and any electronic devices are prohibited. This "closed personal materials, open state materials" setup means your prep should focus heavily on navigating the code book and reference manual quickly - knowing which chapter and table to flip to under time pressure - rather than memorizing every clause outright. The official examination guide referencing this format is dated June 2020, so make sure any materials you study from reflect the current code edition DLI actually issues at the test site.
Fees, Registration, and Licensing Mechanics
The QC exam application costs $50 per attempt, and this fee is nonrefundable regardless of outcome. If you don't pass, DLI requires a 30-day waiting period before you can reapply, along with a brand-new application and another $50 fee - there's no discounted retake rate. A full cost comparison across the exam and licensing path is available in the MN-REMOD certification cost breakdown.
Passing the exam creates your QC registration - it does not, on its own, create a business license. To actually operate as a licensed remodeler, the business must separately secure:
- An eligible qualifying person (the individual who passed QC and has a qualifying relationship to the business)
- Liability insurance
- Workers compensation compliance
| Item | Cost |
|---|---|
| Exam application (per attempt) | $50, nonrefundable |
| Initial CR business license | $180 |
| Contractor Recovery Fund assessment (under $1M receipts) | $320 |
| Contractor Recovery Fund assessment ($1M-$5M receipts) | $420 |
| Contractor Recovery Fund assessment (over $5M receipts) | $520 |
| On-time two-year renewal (under $1M receipts) | $505 |
| On-time two-year renewal ($1M-$5M receipts) | $605 |
| On-time two-year renewal (over $5M receipts) | $705 |
The CR business license renews every two years by March 31. Separately, the qualifying person's QC registration runs on its own two-year cycle starting from the date the exam was passed, not tied to the business license calendar. That registration renews automatically once the qualifying person completes 14 approved continuing education hours, including at least one hour of energy-code content and one hour of business management content.
Key Takeaway
Track two separate renewal clocks: the business's CR license (every two years by March 31) and the qualifying person's QC registration (two years from the exam pass date, tied to CE completion).
Who Actually Needs This Credential
QC/CR licensing applies specifically to businesses and individuals performing remodeling work on existing residential structures in Minnesota - additions, kitchen and bath remodels, structural alterations, and similar scope. It does not cover new home construction, which falls under the separate qualifying builder exam and CBR license path.
In practice, the people pursuing this exam tend to be established remodeling contractors formalizing their qualifying-person status, employees being promoted into an ownership or managing role who now need to carry the license personally, or new business owners entering the remodeling trade who need a qualifying person on staff before they can legally operate. If you're evaluating whether this path fits your career goals or your company's staffing needs, the MN-REMOD jobs overview and the ROI analysis on MN-REMOD certification are useful next reads.
Building a Domain-Based Study Plan
Because the exam splits roughly 60/40 between residential code content and statutes/rules, an efficient study plan allocates more total time to the ten technical domains while still setting aside dedicated blocks for business law. Rather than studying domains in the order they're listed, group them by how they show up in real remodel scopes - structural domains together, envelope/insulation domains together, finish-related domains together - since questions often blend related concepts.
Structural Foundation
- Domain 5 (Concrete & Masonry Footings and Foundations) and Domain 6 (Carpentry) - the domains most likely to involve calculation-style or multi-select questions
Envelope and Insulation
- Domain 2 (Energy Code) and Domain 9 (Foam Plastic Insulation), studied together since both hinge on assembly and thermal barrier requirements
Exterior and Life Safety
- Domain 7 (Roofing), Domain 8 (Exterior Finishes), and Domain 3 (Building Planning/Life Safety)
Documentation, Site, and Interior
- Domain 1 (Plans and Specifications), Domain 4 (Sitework), Domain 10 (Interior Finishes), plus a full pass through business statutes and rules
In the final stretch before your scheduled date, shift from reading to practicing the actual question style: five-option choices, multi-select items, and "identify the incorrect statement" formats. A structured walkthrough like the MN-REMOD study guide for passing on your first attempt can help sequence this, and running full-length timed sets on our practice test platform is the closest way to simulate the 330-minute, 110-question pace before test day. If you're still deciding when to sit for the exam relative to your CE and licensing deadlines, the exam dates and scheduling guide covers the timing logistics.
