MI-RB Cheat Sheet 2026: One-Page Review of Must-Know Facts

Quick Facts Snapshot

This is the one-page version of the Michigan Residential Builder License Examination (MI-RB) that you skim the night before test day. Every number below comes straight from the current PSI candidate handbook and LARA's published rules for the individual Residential Builder license - not a limited Maintenance & Alteration exam, and not any other credential that happens to share the "MI-RB" initials.

• Governing body: Michigan Department of Licensing and Regulatory Affairs (LARA), Bureau of Construction Codes.
• Test administrator: PSI Services LLC, computer-based, offered in English and Spanish.
• Exam or retest fee: $117.
• Initial individual license application fee: $195 (separate from the exam fee).
• Scored questions: 160 total (50 Business and Law + 110 Practice/Trade), plus up to 10 unscored experimental items you cannot identify during the test.
• Time limit: 240 minutes for the full, closed-book, multiple-choice exam.
• Passing score: 116 correct out of 160, or 72.5%.

For the full breakdown of how these numbers were built, see the dedicated MI-RB Passing Score 2026 guide and the MI-RB Certification Cost breakdown.

Exam Format at a Glance

Unlike some state builder exams that split into separate sittings, Michigan's version is delivered as one combined, closed-book, multiple-choice examination. Business and Law and Practice/Trade questions are mixed into a single 240-minute session, and - critically - they are scored together as one examination, including on retakes. You cannot "pass" Business and Law and only need to retake Practice/Trade; a retake means sitting the full 160-question exam again for another $117.

The handbook also lists the 2015 Michigan Residential Code among its examination references, so questions grounded in code language should be expected throughout the Practice/Trade portion, not just in a standalone "code" domain.

All 23 Domains in One Table

Michigan organizes the exam into 23 domains: 8 under Business and Law and 15 under Practice/Trade. The table below is the fastest way to see exactly how many questions each domain contributes. For narrative explanations of what each domain actually tests, cross-reference the MI-RB Exam Domains 2026 complete guide.

Add the Business and Law column and you get exactly 50; add the Practice/Trade column and you get exactly 110 - the two halves of the 160-question exam.

Business and Law Cheat Sheet (Domains 1-8)

Regulatory and Statutory Requirements is the single heaviest domain in this half of the exam at 13 questions, followed by Insurance, Bonds and Liens at 11. Together those two domains alone account for nearly half of all Business and Law questions, so they deserve first priority in any final review pass.

The remaining six domains - Types of Business Organization, Estimating, Contracts, Project Management and Administration, Accounting and Finance, and Personnel - are smaller individually but still worth full mastery, since Estimating alone contributes just 1 question while Contracts contributes 7. A single missed easy question in a low-weight domain hurts the same as one in a high-weight domain.

Practice/Trade Cheat Sheet (Domains 9-23)

Practice/Trade is where Michigan's exam earns its reputation for depth. Carpentry sits at 16 questions, making it the largest domain on the entire 160-question exam - larger than any single Business and Law domain. Plans, Specifications and Estimating (14 questions) and Footings and Foundation Walls (11 questions) round out the top three Practice/Trade domains.

Domains like Ventilation and Specialties carry only 2 questions each, and Estimating (Business and Law side) carries just 1 - these are still fair game but should get proportionally less of your final review time. For a domain-by-domain study plan built around these exact weights, see the MI-RB Study Guide 2026.

Registration and Fee Mechanics

Money and paperwork mistakes cause avoidable delays. Here is the mechanical sequence:

1. Complete 60 hours of LARA-approved prelicensure education.
2. Submit your individual license application to LARA, including a physical Michigan business address, identification, education verification, and good-moral-character certification.
3. Get LARA approval before you can schedule a test with PSI.
4. Pay the $117 exam fee and sit the 240-minute, 160-question combined exam.
5. If you pass, pay the $195 initial individual license application fee to activate licensure.

A company and its qualifying officer maintain their respective licenses separately - passing the exam individually does not automatically license a business entity.

Prelicensure Education Checklist

Before you're eligible to sit for the exam, standard applicants must complete 60 hours of approved prelicensure education. That total is not freeform - it's structured:

• At least six hours in each of seven prescribed subject areas (36 hours minimum across the required set).
• 18 elective hours to fill out the remaining balance of the 60-hour total.

Once you understand exactly what LARA and PSI expect procedurally, the next natural question is how tough the content itself actually is - covered in How Hard Is the MI-RB Exam? and, if you're still deciding whether to pursue licensure at all, in Is the MI-RB Certification Worth It?.

Final Review Schedule by Domain Weight

In the last stretch before test day, allocate review time proportional to each domain's question count rather than spreading effort evenly across all 23 domains. A four-week compressed review built directly off the weight table above looks like this:

This is a compressed structure, not a replacement for a full study plan - the detailed week-by-week approach lives in the MI-RB Study Guide. If you want to gauge readiness before committing to this schedule, run a timed set on the MI-RB practice test platform first.

Renewal and Continuing Education

Passing the exam is the beginning of an ongoing obligation, not the end of one. Individual licenses renew every three years by May 31 in the license's assigned renewal year, and renewal years are staggered across licensees. The renewal fee is $150.

• First two renewal cycles: 21 continuing-education hours required each cycle.
• Every cycle after that: 3 continuing-education hours required.
• Recordkeeping: retain completion records - LARA can audit them.

Last-Minute Review Traps

A few recurring mistakes show up in candidate reports right before test day:

• Treating Business and Law as an afterthought. It's still 50 of your 160 questions - nearly a third of the exam - and it's scored together with Practice/Trade.
• Ignoring low-weight domains entirely. Estimating carries just 1 question and Specialties and Ventilation carry 2 each, but skipping them completely leaves easy points on the table.
• Underestimating the 240-minute pace. With 160 scored questions plus up to 10 unscored ones, you have roughly a minute and a half per question on average - practice under real time pressure rather than untimed drilling.
• Confusing raw score with percentage. The pass threshold is stated both ways - 116 correct and 72.5% - and they describe the same target.
