- The MN-REMOD exam covers 10 technical domains plus separate business statutes and rules content.
- You have 330 minutes for 110 multiple-choice questions and need a 70% score to pass.
- DLI reports roughly 60% of questions come from residential-code content, not general business material.
- All questions carry equal point value with no partial credit, so five-option and multi-select items matter equally.
Exam Overview: Why the Domains Matter
The Minnesota Residential Remodeler License Exam (MN-REMOD) is the qualifying remodeler examination - often abbreviated QC - administered in person by the Minnesota Department of Labor and Industry (DLI), Construction Codes and Licensing Division. Passing QC is what allows an individual to serve as the qualifying person for a residential remodeler business (CR) license. It is a distinct credential from the qualifying builder examination, and the scope of what CR authorizes matters just as much as the score you earn: a CR license covers work on existing residential structures, not the construction of new homes or detached garages.
DLI organizes the technical content of the exam into ten domains. Understanding what each domain actually tests - not just its title - is the difference between guessing on unfamiliar wording and recognizing exactly what the 2020 Minnesota Residential Code section is asking. This guide breaks down all ten domains in the order they appear on the official exam guide, dated June 2020, and explains how they fit into the exam's overall structure.
MN-REMOD Question Format and Structure
Before drilling into domain content, it helps to understand the mechanics you'll face on test day. DLI's exam guide lays out a consistent format:
- 110 multiple-choice questions in a single sitting
- 330 minutes allotted to complete the exam
- 70% minimum passing score - no partial credit on any item
- Five answer options per question, with some items requiring multiple correct selections or asking you to identify the one incorrect statement among the choices
- Administered in person, with DLI supplying the 2020 Minnesota Residential Code, the DLI Reference Manual for Residential Building Contractor and Remodeler License Exam, and a standard desktop calculator
- No personal reference books, notes, or electronic devices allowed at your seat
Because every question is worth the same amount regardless of difficulty or domain, a tricky multi-select item on Domain 9 (Foam Plastic Insulation) counts exactly as much as a straightforward question on Domain 6 (Carpentry). That flat scoring structure is a key reason candidates shouldn't skip the smaller domains just because they sound less central to daily remodeling work - see the MN-REMOD Passing Score breakdown for how the 70% threshold interacts with 110 equally-weighted questions.
Key Takeaway
Since there's no partial credit and every question counts the same, don't triage by domain size - build baseline competence across all ten before test day.
Domain 1: Plans and Specifications
Plans and Specifications
This domain tests your ability to read and interpret construction documents the way a code official or general contractor would - plan symbols, dimensioning conventions, and how specifications relate back to code-required details.
- Reading elevation and section drawings for remodel scope
- Recognizing where specifications override or supplement drawn details
- Identifying missing or inconsistent information that would trigger a plan review question
Domain 2: Energy Code (Envelope Criteria)
Energy Code (Envelope Criteria)
This domain focuses on the building envelope requirements within Minnesota's energy code - insulation, air sealing, fenestration, and how envelope performance requirements apply specifically to remodel and addition work rather than new construction.
- Envelope component requirements as they apply to existing-structure remodeling
- Air barrier and insulation continuity concepts
- Fenestration (window/door) performance criteria
Energy code knowledge doesn't end at the exam. Once you pass, DLI's continuing education requirement for maintaining your QC registration specifically mandates at least one energy-code CE hour every two-year cycle - so this domain has staying power well beyond test day.
Domain 3: Building Planning/Life Safety
Building Planning/Life Safety
This domain covers the code provisions that protect occupants - egress, fire separation, smoke and carbon monoxide alarm placement, and general life-safety planning as it applies to remodeled or altered residential spaces.
- Egress window and door requirements in remodel scenarios
- Smoke and CO alarm placement triggered by remodel work
- Fire-rated separation requirements between dwelling units or attached garages
Domain 4: Sitework
Sitework
Sitework questions address grading, drainage, and site-related code provisions that affect how a remodel project - especially additions - interacts with the surrounding lot.
- Grading and drainage away from the foundation
- Site preparation requirements tied to additions or exterior remodel work
- Erosion and sediment control basics as they intersect with residential code
Domain 5: Concrete & Masonry Footings and Foundations
Concrete & Masonry Footings and Foundations
This domain tests footing and foundation requirements from the residential code - sizing, reinforcement, and masonry provisions relevant to remodel and addition scenarios where new foundation work ties into existing structures.
- Footing depth and sizing requirements
- Foundation wall and masonry code provisions
- Connections between new foundation work and existing structures
Domain 6: Carpentry
Carpentry
Carpentry is one of the most hands-on domains, covering framing methods, structural member sizing, and connection details that residential remodelers apply constantly on the job.
- Framing member spans and sizing tables
- Structural connections and fastening schedules
- Load path considerations in remodel and addition framing
Domain 7: Roofing
Roofing
Roofing questions cover residential code requirements for roof coverings, underlayment, flashing, and ventilation as they apply to reroofing and remodel projects.
- Roof covering and underlayment requirements
- Flashing details at penetrations, valleys, and transitions
- Attic and roof ventilation code provisions
Domain 8: Exterior Finishes
Exterior Finishes
This domain addresses siding, exterior cladding, and weather-resistive barrier requirements - a frequent focus for remodelers replacing or upgrading exterior finishes on existing homes.
- Weather-resistive barrier and drainage plane requirements
- Siding installation and clearance provisions
- Code requirements for exterior finish transitions and flashing integration
Domain 9: Foam Plastic Insulation
Foam Plastic Insulation
A narrower but exam-relevant domain covering thermal barrier requirements, ignition barriers, and code limitations on foam plastic insulation use in residential remodel applications.
- Thermal barrier requirements over foam plastic
- Ignition barrier exceptions and when they apply
- Approved foam plastic applications in basement and attic remodels
Domain 10: Interior Finishes
Interior Finishes
The final technical domain covers wall and ceiling finish materials, including fire-rating and flame-spread requirements that apply to interior remodel work.
- Gypsum board and interior finish material requirements
- Flame-spread and smoke-development ratings for interior finishes
- Interior finish requirements in fire-separated spaces
Code Content vs. Statutes and Rules
The ten domains above represent the technical, code-based knowledge areas, but they don't make up the entire exam. DLI describes roughly 60% of exam questions as residential-code content pulled from these ten domains, with the remaining share addressing industry statutes and rules - licensing requirements, business practices, and regulatory obligations that fall outside the 2020 Minnesota Residential Code itself.
This split matters for study planning. Candidates who focus exclusively on code sections and skip statutory material are leaving a meaningful portion of the exam unaddressed. For a full breakdown of how statutes and rules questions are typically structured alongside the ten technical domains, see the MN-REMOD Study Guide.
| Content Area | Approximate Share | Source Material |
|---|---|---|
| Residential Code (10 domains) | ~60% of questions | 2020 Minnesota Residential Code |
| Industry Statutes and Rules | Remaining share | DLI Reference Manual and licensing statutes |
Mapping the Domains to a Study Schedule
With ten technical domains plus statutes and rules to cover in 330 exam minutes, sequencing your prep matters more than cramming. A domain-first approach - working through the heavier, code-dense areas early and saving narrower domains for review weeks - tends to fit the structure of this exam better than a generic weekly template.
Structural and Envelope Foundations
- Domain 5 (Concrete & Masonry Footings and Foundations)
- Domain 6 (Carpentry)
- Domain 2 (Energy Code / Envelope Criteria)
Envelope and Exterior Systems
- Domain 7 (Roofing)
- Domain 8 (Exterior Finishes)
- Domain 9 (Foam Plastic Insulation)
Life Safety, Planning, and Site
- Domain 3 (Building Planning/Life Safety)
- Domain 4 (Sitework)
- Domain 1 (Plans and Specifications)
Interior Finishes and Statutes Review
- Domain 10 (Interior Finishes)
- Industry statutes and rules review
- Full-length timed practice under 330-minute conditions
If six weeks feels ambitious given your schedule, adjust the pace rather than the sequence - the order in which structural, envelope, and finish domains build on one another stays useful. For candidates weighing how much total prep time this exam actually demands, How Hard Is the MN-REMOD Exam? covers difficulty expectations in more depth, and a full practice test is one of the fastest ways to see which domains need another pass before you commit to a test date.
What Happens After You Pass
Passing the MN-REMOD exam creates your QC registration - it does not, by itself, grant you a CR business license. To actually operate as a licensed residential remodeler, the business also needs an eligible qualifying person relationship, liability insurance, and workers' compensation compliance in place separately.
Two separate renewal clocks then start running:
- QC registration runs on a two-year cycle from your exam passing date and renews automatically once you complete 14 approved continuing education hours, including at least one energy-code hour and one business-management hour.
- CR business license renews every two years by March 31, with on-time renewal totals of $505, $605, or $705 depending on gross annual receipts tier.
Initial business licensing carries its own cost structure too - a $180 license fee plus a Contractor Recovery Fund assessment of $320, $420, or $520 based on gross annual receipts. For the complete fee picture across application, licensing, and renewal, see the MN-REMOD Certification Cost breakdown.
If you don't pass on your first attempt, DLI requires a 30-day wait before reapplying, along with a new $50 application fee - reinforcing why a domain-by-domain study approach beats rushing in underprepared.
Key Takeaway
Passing QC is a milestone, not the finish line - track your separate CE renewal cycle and CR business license renewal deadlines so registration doesn't lapse.
Frequently Asked Questions
There are 10 official technical domains, ranging from Plans and Specifications through Interior Finishes, plus separate industry statutes and rules content that isn't tied to a specific numbered domain.
DLI does not publish a per-domain weighting breakdown. What is documented is that all 110 questions carry equal point value with no partial credit, and that roughly 60% of questions overall address residential-code content across the 10 domains.
No. DLI does not require prerequisite education or work experience to sit for the MN-REMOD exam, though the qualifying person must have an eligible ownership, officer, or managing-employee relationship to the business.
None of your own. DLI supplies the 2020 Minnesota Residential Code, the DLI Reference Manual for Residential Building Contractor and Remodeler License Exam, and a standard desktop calculator. Personal reference books, notes, and electronic devices are prohibited.
The exam produces a single overall pass/fail result at the 70% threshold, not domain-by-domain pass marks. If you don't reach 70%, you must wait 30 days and submit a new application and $50 fee to retake the full exam.
