What Does BC-A,B Mean?

Tennessee divides building contractor licenses into different classifications based on the type of construction you want to perform.

Put them together and you get BC-A,B, a combined residential and full commercial building classification.

BC-A,B vs. BC-A,b(sm): Know the Difference

The names are annoyingly similar, but the difference can have a major effect on the projects you can contract.

If you expect your commercial projects to grow beyond $1.5 million, BC-A,B may make more sense than BC-A,b(sm).

If you also need industrial construction authority, then you should compare BC-A,B with the full BC Residential / Commercial / Industrial classification.

What Types of Projects Can a BC-A,B Contractor Take?

The residential side can include qualifying:

• Single-family homes.
• Duplexes.
• Three-family residences.
• Four-family residences.
• Residential additions and remodeling.
• Accessory-use structures connected to residential work.

The commercial side can include qualifying:

• Office buildings.
• Retail stores.
• Restaurants.
• Warehouses.
• Schools.
• Churches.
• Commercial renovations.
• Multifamily buildings with more than four units.
• Residential buildings exceeding three stories.
• Other commercial buildings for public use and occupancy.

The current Prov description also states that the BC-A,B examination covers all 34 Tennessee building categories applicable to residential and commercial construction.

When Is a Tennessee Contractor License Required?

Tennessee generally requires a contractor license before contracting for a project of $25,000 or more.

"Contracting" starts earlier than some people expect. It can include:

• Bidding.
• Offering to perform the work.
• Negotiating the price.
• Signing the contract.
• Acting as a qualifying construction manager or consultant.

Tennessee wants the license in place before the regulated contracting activity happens.

Winning a giant bid and then starting your license application is a little like buying a plane ticket and beginning flight school on the way to the airport.

Review the Tennessee Contractor Licensing requirements before bidding.

Step 1: Choose the Business Entity That Will Hold the License

Tennessee issues the contractor license to the approved business entity.

The entity may be:

• A sole proprietor.
• A partnership.
• A corporation.
• An LLC.

Corporations, LLCs, and applicable partnerships must be properly registered with the Tennessee Secretary of State.

Keep the legal business name consistent across your:

• Contractor application.
• Financial statement or qualifying surety bond.
• Insurance.
• Secretary of State registration.
• Other licensing documents.

One missing comma in an LLC name can sometimes create more paperwork than an entire set of building plans.

Step 2: Select a Qualifying Agent

Tennessee uses the term Qualifying Agent, or QA, for the individual who qualifies the business for the contractor classification.

The QA is normally the person who passes the required trade examination.

A QA may be an:

• Owner.
• Officer.
• Partner.
• Qualifying full-time employee.

Tennessee's current QA guidance says a full-time employee QA may generally be listed on only one contractor license. A person with majority ownership in multiple companies may qualify those companies when the Board's requirements are met.

Step 3: Build Relevant Residential and Commercial Experience

Tennessee reviews experience when deciding whether an applicant qualifies for the requested classification and monetary limit.

The Board's application guidance states that it prefers approximately three years of relevant experience.

For BC-A,B, strong experience can include:

• Residential building construction.
• Commercial building construction.
• Estimating and bidding.
• Plan reading.
• Sitework.
• Foundations.
• Concrete.
• Masonry.
• Structural steel.
• Carpentry.
• Roofing.
• Interior finishes.
• Commercial code compliance.
• Scheduling.
• Subcontractor management.
• Jobsite safety.

The Board also considers whether your experience makes sense for the monetary limit you request.

If you request authority for very large projects, be ready to show experience with work of meaningful size and complexity.

Step 4: Register for the Correct BC-A,B Exam

Tennessee offers several building exams with similar names.

For this classification, the trade exam is:

Do not accidentally register for:

• BC-A Residential.
• BC-b(sm) Small Commercial.
• BC-A,b(sm) Residential / Small Commercial.
• BC-B Commercial only.
• BC Residential / Commercial / Industrial.

Prov specifically warns candidates to determine the correct exam before registering because the examination provider does not decide which classification you need.

Step 5: Understand the Current BC-A,B Exam

Tennessee's current Prov examination for BC-A,B is:

• 100 questions.
• 2-hour time limit.
• 73% passing score.
• $53 examination fee.
• Open book.

Two hours for 100 questions gives you an average of only 72 seconds per question.

That is fast.

An open-book exam can feel comforting until you realize the clock has absolutely no interest in watching you read an entire chapter about concrete.

Speed, reference organization, and knowing where information lives are critical.

Step 6: Know the BC-A,B Exam Breakdown

The current Prov outline divides the 100 questions into these subject areas:

Estimating, code, concrete, masonry, and structural steel make up a very large part of the current examination.

That commercial emphasis is one reason BC-A,B preparation feels different from studying for BC-A residential alone.

Step 7: Get the Correct Exam References

Prov currently lists the following primary references for the BC-A,B examination:

• International Building Code, 2021.
• International Residential Code, 2021.
• Study Guide for Commercial Building Contractor, 2024.
• OSHA 29 CFR Part 1926.
• Residential Home Builder Study Guide.

Through January 1, 2027, Prov is also allowing certain reference books approved under Tennessee's previous PSI testing program.

After that transition date, candidates should expect Prov's listed references to control unless the testing program announces another change.

One option is the Tennessee BC-A,B Combined Residential / Commercial Contractor Complete Book Package.

Step 8: Prepare Your Open-Book References Correctly

Prov permits reference preparation, but the rules are strict.

Current rules allow:

• Highlighting.
• Underlining in pen.
• Permanent tabs.
• Approved reference books.

Current rules prohibit:

• Handwritten notes.
• Moveable or repositionable tabs.
• Post-it notes.
• Loose added documents.
• Photocopied pages added to books.
• Unauthorized practice exams.
• Unauthorized exam-prep guides in the testing room.

You also cannot mark in the books while the exam is underway.

Candidates who want organized exam references can review the Tennessee BC-A,B Highlighted & Tabbed Book Package.

Step 9: Learn the International Building Code

The 2021 International Building Code is one of the most important commercial references on the exam.

Practice locating:

• Occupancy classifications.
• Construction types.
• Allowable building heights.
• Allowable areas.
• Fire-resistance ratings.
• Fire barriers and partitions.
• Means of egress.
• Exit requirements.
• Accessibility provisions.
• Interior finishes.
• Special inspections.
• Structural requirements.

Do not simply read the IBC from beginning to end.

Practice using questions to identify the correct chapter, table, exception, and footnote.

Step 10: Do Not Ignore the Residential Side

BC-A,B is a combined examination, so commercial preparation alone is not enough.

Be comfortable with residential topics including:

• Building planning.
• Residential foundations.
• Floor construction.
• Wood wall framing.
• Roof and ceiling construction.
• Stairs and guards.
• Weather protection.
• Residential insulation.
• Residential building systems.

A combined license means combined studying. The exam is not going to politely separate itself into "house morning" and "commercial afternoon."

Step 11: Practice Concrete, Masonry, and Structural Steel

These three areas alone account for a major share of the current BC-A,B exam.

Review:

• Concrete quantities.
• Reinforcement.
• Placement and curing.
• Footings.
• Masonry units.
• Mortar and grout.
• Masonry reinforcement.
• Structural steel terminology.
• Steel framing.
• Connections.
• Commercial structural construction methods.

These subjects are especially important for contractors moving from mostly residential work into full commercial construction.

Step 12: Practice Estimating and Plan Reading

Estimating and plan reading currently account for 15 questions, making this one of the largest sections on the exam.

Practice:

• Reading floor plans.
• Reading elevations.
• Understanding building sections.
• Reading details.
• Using drawing scales.
• Calculating areas.
• Calculating volumes.
• Estimating concrete.
• Estimating masonry.
• Estimating roofing.
• Understanding construction sequencing.

Good estimating skills help you pass the exam and have the additional benefit of keeping your company from accidentally donating materials to every customer.

Step 13: Study OSHA Safety

OSHA currently accounts for six questions on the trade examination.

Review common construction-safety areas such as:

• Fall protection.
• Scaffolds.
• Ladders.
• Excavations.
• Personal protective equipment.
• Electrical jobsite hazards.
• Power tools.
• Material handling.

Six questions may not sound enormous, but a licensing exam is a terrible place to voluntarily donate six points.

Step 14: Use Timed Practice Exams

The two-hour time limit should shape your entire study plan.

1. Study one subject at a time.
2. Answer practice questions without a timer.
3. Find each answer in the proper reference.
4. Review every incorrect answer.
5. Repeat the subject under time pressure.
6. Practice switching rapidly between the IBC, IRC, OSHA, and study guides.
7. Complete full 100-question timed practice sessions.

Track slow correct answers as well as wrong answers.

Finding the right answer in five minutes is great during study. During a 72-second-per-question exam, it needs improvement.

For structured preparation, review the Tennessee BC-A,B Combined Residential / Commercial Online Exam Prep Course.

Step 15: Pass Tennessee Business and Law

New Tennessee contractor applicants normally also need the separate Tennessee Contractor Business and Law examination.

The current test contains:

• 50 questions.
• 73% passing score.
• $53 exam fee.
• Open-book format.

Tennessee is still coming out of its 2026 exam-provider transition. Prov's current online examination page displays a 2.5-hour allowance for Business and Law, while the June 2026 PDF bulletin lists 2 hours.

Business and Law covers:

• Business organization.
• Licensing.
• Estimating and bidding.
• Contracts.
• Project management.
• Risk management.
• OSHA safety.
• Financial management.
• Labor law.
• Tax law.
• Lien law.

Step 16: Choose Your Financial Qualification Method

Tennessee assigns every contractor license a monetary limit.

You currently have two major financial qualification approaches.

Review the Tennessee Contractor Forms and Financial Resources before choosing the option that fits your business.

Step 17: Understand the Monetary Limit

Your classification tells Tennessee what kind of work you may perform.

Your monetary limit tells Tennessee how large a project you may contract.

Under the traditional financial-statement method, the Board commonly bases the monetary limit on up to ten times the lesser of:

• Working capital.
• Net worth.

Experience also matters.

For example, qualifying financially for a large monetary limit does not guarantee that the Board will approve it if your construction history does not demonstrate experience at that level.

Step 18: Obtain General Liability Insurance

Tennessee requires general liability insurance, with the minimum amount based on your monetary limit.

• Monetary limit up to $500,000: at least $100,000 coverage.
• $500,001 through $1,500,000: at least $500,000 coverage.
• More than $1,500,000 through Unlimited: at least $1,000,000 coverage.

Your Certificate of Insurance should identify the properly licensed business entity and comply with the Board's certificate-holder requirements.

A quote or insurance invoice is not the same thing as the required Certificate of Insurance.

Step 19: Handle Workers' Compensation

Tennessee contractor applicants also need to address workers' compensation.

Depending on the business structure, employees, subcontractors, and available exemptions, you may need:

• Workers' compensation insurance.
• Construction Services Provider exemption documentation.
• Other exemption documentation allowed under Tennessee law.

The licensing requirement and your real-world insurance obligations on a specific project are not always identical, so work with your insurance professional and Tennessee authorities when necessary.

Step 20: Submit the Tennessee Contractor Application

After your exams and supporting documents are ready, submit your application to the Tennessee Board for Licensing Contractors.

Tennessee currently uses the CORE online licensing system.

The current initial contractor application fee is $250.

Your application can require:

• Business entity information.
• Qualifying Agent information.
• BC-A,B trade exam score.
• Business and Law score.
• Experience information.
• Letter of reference.
• Financial statement or qualifying surety bond.
• General liability insurance.
• Workers' compensation information or exemption.
• Secretary of State documents when applicable.
• Affidavits and disclosures.

Passing the exam is not the same thing as receiving the license.

The Board must approve the application and issue the license before you operate under the BC-A,B classification.

What Happens If You Fail?

Prov currently allows Tennessee contractor candidates to retake an unsuccessful examination as many times as needed.

There is currently:

• No mandatory waiting period between failed attempts.
• No Board limit on the number of retakes.
• A new $53 exam fee for each attempt.

After two failed attempts, candidates who score within 10 points of the required 73% may qualify for an examination review under the current Prov policy.

Use the diagnostic report to adjust your study plan. If concrete and structural steel caused the damage, studying roofing for another week is probably not the heroic comeback strategy you need.

Can You Take the Tennessee Exam From Home?

Yes. Prov currently offers remote testing through Examroom for Tennessee contractor candidates, in addition to physical testing locations.

Prov also operates Tennessee-based testing locations and testing facilities elsewhere in the United States.

Remote candidates need to meet the current technical, room, identity, and proctoring requirements.

Your approved books must still comply with the same reference rules.

Does Tennessee Accept the NASCLA Commercial Exam?

Tennessee currently accepts the NASCLA National Commercial examination for the BC-B commercial classification.

That can be useful for contractors who already passed NASCLA or plan to pursue licenses in multiple NASCLA-participating states.

However, BC-A,B is a combined residential and commercial classification.

Does Tennessee Have Reciprocity?

Tennessee has trade-exam waiver agreements with several states.

Current participating contractor jurisdictions include certain classifications from:

• Alabama.
• Arkansas.
• Louisiana.
• Mississippi.
• North Carolina.
• South Carolina.
• West Virginia.
• Other states for specific trades.

Reciprocity is a trade-exam waiver, not permission to work in Tennessee using another state's contractor license.

Reciprocal applicants still need the Tennessee license and must satisfy the state's remaining application, business, financial, insurance, and Business and Law requirements when applicable.

How Long Is the Tennessee Contractor License Valid?

A Tennessee contractor license is generally issued for two years.

The current renewal fee is $200.

Renewal may require:

• Updated financial documentation or qualifying surety bond.
• Current general liability insurance.
• Workers' compensation or exemption documentation.
• Active Tennessee Secretary of State registration when applicable.
• Responses to renewal questions and disclosures.

Do not continue contracting after expiration while assuming a grace period will save you. Tennessee specifically warns that an expired contractor license is not authorized to continue operating.

Does BC-A,B Require Residential Continuing Education?

This is an important difference from the BC-A,b(sm) classification.

Tennessee's current Residential Continuing Education rule and Board RCE page specifically identify:

• BC-A.
• BC-A/r.
• BC-A,b(sm).

The current rule does not expressly list BC-A,B among the classifications required to complete the eight-hour Residential Continuing Education program.

Helpful Tennessee BC-A,B Resources

Frequently Asked Questions

Here are common questions about becoming a Tennessee BC-A,B Combined Residential / Commercial Contractor.

Key Takeaways

• BC-A,B combines Tennessee residential and full commercial building authority. Unlike BC-A,b(sm), it does not carry the $1.5 million small-commercial classification cap, although your Board-approved monetary limit still controls project size.
• The current BC-A,B trade exam has 100 questions and only two hours. Candidates need 73% to pass, so fast open-book navigation is a major part of preparation.
• The current trade references include the 2021 IBC, 2021 IRC, 2024 Commercial Building Contractor Study Guide, OSHA 29 CFR 1926, and Residential Home Builder Study Guide.
• Business and Law is a separate licensing exam. Passing the trade test alone does not complete the Tennessee contractor licensing process.
• Exams are only part of licensing. Tennessee also considers experience, financial strength, monetary limits, insurance, the Qualifying Agent, business registration, and Board approval.

Final Thoughts Before You Start

Tennessee's BC-A,B Combined Residential / Commercial Contractor classification is a strong option for contractors who want room to grow.

BC-A gives you the residential side of the business. BC-B opens the door to full commercial building construction. Together, they can cover everything from a new single-family home to offices, retail spaces, warehouses, schools, churches, and larger multifamily projects, all subject to your actual license monetary limit.

That broader scope is the biggest reason to compare BC-A,B carefully with BC-A,b(sm). The small-commercial combination can be a great license, but its commercial classification stops at $1.5 million. BC-A,B removes that classification cap and lets the Board-approved monetary limit determine how large your projects can become.

The broader license also means a broader exam.

The current BC-A,B test has 100 questions covering residential and commercial construction, and you only get two hours. That works out to about 72 seconds per question. You cannot treat an open-book test like a leisurely research project.

Learn the references before test day. Know when to open the IBC, when to use the IRC, where OSHA information lives, and which study guide is most likely to answer a construction-method question. Practice finding answers instead of simply reading books.

Give extra attention to estimating, general code, concrete, masonry, and structural steel. Those subjects carry a lot of weight on the current exam. Residential knowledge still matters too, especially because this is a combined classification.

Do not ignore Business and Law. A successful contractor has to understand contracts, bidding, licensing, taxes, liens, financial management, risk, and project management. Knowing how to construct a building is only half the battle if the paperwork quietly sets the other half on fire.

After the exams, focus on your contractor application. Choose the right business entity, keep the Qualifying Agent properly connected to the company, request a monetary limit that makes sense for your finances and experience, obtain the required insurance, and make sure your supporting documents all use the same legal business name.

Tennessee's new 2026 surety bond option also gives applicants another way to meet financial qualification requirements when the current rules are satisfied. That may be worth discussing with your financial and surety professionals if a traditional CPA financial statement is not the route you want to use.

When you are ready to organize your exam preparation, explore the Tennessee BC-A,B Combined Residential / Commercial Contractor resources from 1 Exam Prep. A focused study plan, properly prepared reference books, timed practice, and a clear licensing strategy can turn a very broad contractor exam into a process that feels much more manageable.
