Louisiana Raises Insurance Minimum, Adds Fourplex Roofing and Well Rules

The Louisiana State Licensing Board for Contractors has raised the minimum liability insurance required of residential, home improvement and mold remediation licensees from $100,000 to $500,000, effective August 1, 2026. The same round of changes brings buildings with up to four dwelling units under the state's residential roofing licensing rule and creates a new license requirement for water well and environmental well work, starting at a project value of $1.

This article covers what the board's July 13, 2026 memo and the underlying statutes say, and what the changes mean for contractors already licensed in Louisiana and for companies that want to work there.

At a glance

• Who: the Louisiana State Licensing Board for Contractors (LSLBC), under Act 757 and Act 481 of the 2026 Regular Session.
• What changed: a higher liability insurance minimum, a fourplex rule for residential roofing, and a new water well and environmental well licensing requirement.
• When: the water well licensing rule took effect July 1, 2026. The insurance increase and the roofing rule take effect August 1, 2026.
• Who it affects: residential construction, home improvement and mold remediation licensees (insurance); anyone bidding or performing roofing work on a building with up to four dwelling units (roofing); anyone bidding, constructing, modifying, repairing or maintaining a water well or environmental well or hole (water well).

The liability insurance minimum goes to $500,000

Residential construction and its subclassifications, mold remediation, and home improvement applicants and licensees must now carry at least $500,000 in liability insurance, or $500,000 in liability protection through an authorized liability trust fund, up from the previous $100,000 minimum. The board's memo states the requirement directly: licensees "must maintain at least $500,000 in liability insurance or qualifying liability protection through an authorized liability trust fund."

Proof of the coverage has to come from the licensee's agent, broker or insurer, not from the licensee directly. It must identify the licensee, the insurer, the broker and the broker's address, the policy number, and the coverage dates. It must cover at least six months, include every scope of work the licensee is licensed to perform with no exclusions, and list the board as the certificate holder. Required workers' compensation and liability protection must stay continuously in effect while the license or registration is active.

Fourplex buildings now count as residential roofing

For residential roofing specifically, the board now treats a building used primarily as a residence and containing up to four dwelling units in one structure as a residential roofing project. A person who advertises, solicits, quotes, bids, contracts, supervises or performs roofing work worth $7,500 or more on that kind of building needs the Residential Roofing or Residential Construction classification.

The practical effect lands on duplexes, triplexes and fourplexes. Roofing work on those buildings, once it reaches the $7,500 project value, now falls under the same residential roofing licensing rule as a single family home.

A license for water well and environmental well work, from the first dollar

The lowest threshold in this round of changes covers water wells and environmental wells or holes. Since July 1, 2026, a person who advertises, solicits, quotes, bids, supervises, directs, oversees, constructs, modifies, repairs or maintains any part of a water well or environmental well or hole for a project worth $1 or more needs the appropriate LSLBC license and classification, subject to applicable exemptions.

The licensing covers potable and nonpotable water wells, along with specialized borings used for environmental assessment, sampling or analysis, including observation, monitor, piezometer, recovery, horizontal, cathodic protection and geotechnical boreholes. A water well or environmental well contractor must pass the appropriate examination, register with the board, stay in good standing with the Louisiana Department of Conservation and Energy, and complete five hours of board approved continuing education every year.

Also starting August 1, 2026, the general exemption that lets a subcontractor work for a residential construction license holder without holding their own license stops covering water well work. A subcontractor performing water well work for a residential construction license holder now has to hold the appropriate license and classification, and contract directly with that license holder.

What this means for contractors already licensed in Louisiana

Any residential construction, home improvement or mold remediation licensee needs to check its current liability policy against the new $500,000 minimum before the August 1, 2026 effective date. A policy sitting at the old $100,000 level will not meet the requirement, and the board's own notice to license holders warns that failing to meet the new standard can lead to suspension of licensure.

Roofing contractors working on small multifamily buildings should recheck whether a duplex, triplex or fourplex roofing job now needs the Residential Roofing or Residential Construction classification. Anyone who touches water wells, including as a subcontractor on a residential job, needs to confirm licensing and registration before starting work worth more than a dollar.

For companies that want to work in Louisiana

The LSLBC issues licenses by major classification, including Residential Construction, Mold Remediation and Home Improvement, each requiring a qualifying party who meets the exam and experience requirements for that classification. The Louisiana contractor license page covers the classifications, the financial and insurance requirements, and the rules for replacing a qualifying party.

A company whose owner does not yet hold the experience or exams for a classification can be qualified by a licensed qualifying agent who is an owner or a full time employee and who supervises the company's work. Contractor qualifier services explains how The Licensing Company helps with that.
