Contractors in Louisiana are licensed by the Louisiana State Licensing Board for Contractors (LSLBC) under La. R.S. Title 37, Chapter 24 (R.S. 37:2150 et seq.). The board sets standards and exam requirements, issues credentials, and enforces the licensing law statewide.La. R.S. 37:2150 et seq.

A Louisiana commercial contractor license is required for commercial work costing at least:

• a.$7,500
• b.$100,000
• c.$50,000✓
• d.$10,000

A commercial contractor license is required for commercial work of $50,000 or more under La. R.S. 37:2150.1. The threshold applies to public and private commercial projects.La. R.S. 37:2150.1

The electrical, mechanical, and plumbing (E/M/P) classifications in Louisiana are licensed at a lower threshold than general commercial work. That E/M/P threshold is:

• a.$75,000
• b.$100,000
• c.$10,000✓
• d.$50,000

The electrical, mechanical, and plumbing classifications carry a $10,000 threshold, lower than the $50,000 general commercial threshold. These three trades are regulated at that reduced dollar level.La. R.S. 37:2150.1 (E/M/P)

A Louisiana residential contractor license is required for new residential construction costing at least:

• a.$7,500
• b.$75,000
• c.$50,000✓
• d.$10,000

Home improvement work in Louisiana requires registration with the LSLBC once the work reaches:

• a.$100,000
• b.$7,500✓
• c.$500
• d.$50,000

Home improvement registration covers work on an existing home of at least $7,500 but less than $50,000, with no structural work. This registration is separate from the full residential or commercial license.La. R.S. 37:2150.1 (home improvement)

• a.$50,000
• b.$100,000

Under La. R.S. 37:2158, when may a person submit a bid on Louisiana work that requires a license?

• a.Only after the final inspection has been passed and the owner has accepted the work
• b.Only when the person already holds the proper license and classification✓
• c.Only after the contract is signed
• d.At any time, because a license is needed only to build and never to submit a bid

La. R.S. 37:2158 makes it a violation to bid or perform work without the required license or the proper classification. The contractor must be licensed before bidding. On a public bid, the license number must appear on the bid envelope (La. R.S. 37:2165).La. R.S. 37:2158

A builder plans a new single-family home in Louisiana with a construction cost of $60,000. A study guide says the residential trigger is $75,000. What is correct?

• a.No residential work is ever licensed in Louisiana
• b.A residential license is required, because new residential construction of $50,000 or more triggers licensing and $75,000 is outdated✓
• c.No license is needed, because the residential trigger is $75,000 and a $60,000 home falls below it, exactly as the study guide says it does
• d.Only a home-improvement registration is needed

New residential construction of $50,000 or more requires a residential license; the $75,000 figure is outdated. A $60,000 new home exceeds the correct $50,000 trigger, so the residential license is required.La. R.S. 37:2150.1 (residential threshold)

A mechanical contractor takes a Louisiana commercial HVAC job worth $15,000. Does this work require a license?

• a.No, because it is under $50,000
• b.No, mechanical work is never licensed
• c.Yes, because the E/M/P threshold is $10,000 and $15,000 exceeds it✓
• d.Only a home-improvement registration is needed

The electrical, mechanical, and plumbing classifications are triggered at $10,000, not $50,000. A $15,000 commercial mechanical job exceeds the E/M/P threshold, so the mechanical license is required even though it is under the general commercial $50,000 line.La. R.S. 37:2150.1 (E/M/P)

What exposure does a person who bids or contracts covered Louisiana work without a license face?

• a.Only a written warning letter from the board, with no fine for a first or any later offense
• b.Fines and other penalties under the statute, plus a weak position to enforce payment✓
• c.A guaranteed award of the contract, since the low bidder must be accepted regardless of licensure
• d.No penalty of any kind

Bidding or contracting work that requires a license without one violates La. R.S. 37:2158 and 37:2163. It exposes the violator to board fines under La. R.S. 37:2164 and criminal penalties under La. R.S. 37:2163. The unlicensed contractor is also in a weak position to enforce payment, because it may not file a claim or lien for money owed (La. R.S. 37:2159). Getting the correct classification before bidding avoids both risks.La. R.S. 37:2163; La. R.S. 37:2164

A contractor performs an $8,000 kitchen remodel with no structural work on an existing Louisiana home. Which credential does this residential improvement work implicate?

• a.No credential, because all residential work is exempt
• b.A home-improvement registration, because the work is $7,500 or more✓
• c.A commercial Building Construction license, because $8,000 is commercial
• d.A Highway, Street, and Bridge classification

Home improvement of at least $7,500 but less than $50,000, with no structural work, requires registration with the LSLBC. An $8,000 non-structural remodel of an existing home falls in that range, so the home-improvement registration applies.La. R.S. 37:2150.1 (home improvement)

A general contractor bids a private Louisiana office build-out priced at $120,000 without any contractor license. What is the core legal problem?

• a.Only mold remediation requires a license
• b.The project exceeds the $50,000 commercial threshold, so bidding without the proper license violates the law✓
• c.The licensing threshold is $75,000 per trade, so the job is exempt once it is divided among three subcontractors
• d.There is no legal problem, because commercial work in Louisiana is unlicensed unless public money pays for it

Commercial work of $50,000 or more requires a commercial license, and it is unlawful to bid such work without it. A $120,000 office build-out far exceeds the threshold, so bidding unlicensed violates La. R.S. 37:2158.La. R.S. 37:2150.1 (commercial threshold)

On a Louisiana public works bid, what license-related information must appear on the bid envelope?

• a.Only the contractor's phone number
• b.Nothing related to licensing
• c.The architect's home address
• d.The contractor's license number✓

La. R.S. 37:2165 requires the contractor's license number on the bid envelope, tying the bidding process to proper licensure. A bid without the license number on the envelope is rejected and not read aloud.La. R.S. 37:2165

A contractor licensed in another state applies for a Louisiana license by reciprocity. What does La. R.S. 37:2153 say about the business law requirement?

• a.It is waived automatically whenever the trade exam is waived
• b.It cannot be waived, although the trade exam may be✓
• c.It is replaced by the other state's law exam
• d.It applies only to Building Construction work

The board may waive the trade portion of the examination for an applicant licensed in a comparable classification in another state. The business law requirement cannot be waived (La. R.S. 37:2153(F)(5)), so the qualifying party still completes the Louisiana Business and Law exam.La. R.S. 37:2153(F)(5)

Who sits the Louisiana Business and Law examination for a contracting company?

• a.A qualifying party for the company✓
• b.No one; companies are exempt from the exam
• c.The company's outside attorney only
• d.Every field laborer individually

A qualifying party for the company sits the Louisiana Business and Law examination. The board requires it of the qualifying party for commercial, residential, and mold remediation applicants. The qualifying party carries the company's examination and responsibility for compliant contracting.LSLBC Business and Law requirement

A candidate passes the NASCLA Accredited Commercial General Building exam and wants a Louisiana Building Construction license. What else is required on the exam side?

• a.Retaking the NASCLA examination every year to keep the license
• b.Nothing more, because NASCLA alone licenses the contractor in every state
• c.Also passing the Louisiana Business and Law examination✓
• d.Passing the Louisiana bar examination administered to attorneys

NASCLA covers only the trade/technical portion for the Building Construction scope. To be licensed, the candidate must also pass the separate Louisiana Business and Law examination administered by the LSLBC.NASCLA + LSLBC Business and Law requirement

Home improvement and mold remediation both start at $7,500 in Louisiana. How are the two credentials classed?

• b.Both are registrations for small jobs, and neither one is ever a license
• c.Mold remediation is a registration; home improvement is a license
• d.Both are unregulated activities until the work reaches $50,000

Home improvement is a registration for work on an existing home of at least $7,500 but less than $50,000, with no structural work (La. R.S. 37:2150.1). Mold remediation of $7,500 or more requires a license and is a major classification (La. R.S. 37:2156.1).La. R.S. 37:2150.1; La. R.S. 37:2156.1

• a.A 50-question test taken online in the LSLBC Contractor Licensing Portal✓
• b.A take-home essay that is graded by the parish clerk of court
• c.A proctored exam booked through PSI at one of its test centers
• d.A hands-on demonstration of trade skills held on a job site

The board describes the Louisiana Business and Law exam as a 50-question test that the qualifying party takes online in the LSLBC Contractor Licensing Portal after approval. A score of 70 or above passes. PSI administers the trade exams, not the Business and Law exam.LSLBC, What Happens After I Apply
