Maine does not license concrete, foundation, or flatwork contractors, and there is no statewide contractor registration. The state layer is consumer law: a contract to build, remodel, or repair a residence of 3 or fewer units for more than $3,000 must be in writing and contain the terms in 10 M.R.S. § 1487, including a down payment capped at one-third of the price.
Excavation for footings, slabs, or driveways falls under Maine's underground facility damage prevention law: excavators must notify the Dig Safe system at least 3 business days, but not more than 30 calendar days, before digging (23 M.R.S. § 3360-A), and the Public Utilities Commission may impose administrative penalties of up to $1,000 for a first violation. Foundation work is inspected locally where MUBEC is enforced (towns over 4,000 residents).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Maine has no state contractor license or registration for this trade, so the state layer is consumer law: the Home Construction Contracts Act applies to residential jobs (3 or fewer units) over $3,000. Building codes are local in practice — the Maine Uniform Building and Energy Code (MUBEC) must be enforced in municipalities with more than 4,000 residents (10 M.R.S. § 9724), through local building officials, shared officials, or certified third-party inspectors (25 M.R.S. § 2373). Smaller towns need not enforce MUBEC but may not adopt any other building code. Electrical, plumbing, and fuel-burning work belongs to state-licensed trades, and towns may not license those trades themselves.
The local offices section below names the exact permit desk for every Maine county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Maine issues no license and keeps no registry for this trade; the Attorney General warns homeowners to research contractors themselves.
Residential jobs over $3,000 need a written contract with the statutory terms; the AG publishes a free model contract and required addendum.
The Public Utilities Commission may impose an administrative penalty of up to $1,000 for a first Dig Safe violation, more for repeats within 12 months.
A practical sequence for a new concrete contractor in Maine. Actual agency processing times are noted in the ledger above.
Each item names the issuing authority, cycle, and citation.
Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Each violation of the Home Construction Contracts Act — no written contract, missing terms, oversized deposit, unwritten change orders — is a civil violation.
A violation of the Act is prima facie evidence of a violation of the Maine Unfair Trade Practices Act, opening the door to Attorney General enforcement and consumer suits.
Doing electrical, plumbing, or fuel-burning installation work without the required state license is unlicensed practice.

Pending verification: Whether any Maine city or town requires its own license or registration for general building trades — no statewide bar was found for general contractors (unlike electricians, plumbers, and fuel technicians, whom 32 M.R.S. §§ 1103, 3302(2), and 18105 protect from municipal licensing); check locally · The exact effective date of the 2021 I-code edition of MUBEC — the 16-642 C.M.R. ch. 5 rule text says it takes effect 90 days after the Public Safety Commissioner's approval, and the Bureau of Building Codes and Standards site blocked automated retrieval, so the date was not confirmed on an official page · Permit practice in municipalities of 4,000 or fewer residents, which need not enforce MUBEC (10 M.R.S. § 9724(1-A)) — whether a building permit is required there depends on local ordinance · Whether every concrete job on a residence (e.g., a detached driveway or patio) counts as a 'home construction contract' to 'build, remodel or repair a residence' under 10 M.R.S. § 1486(4) — the definition does not address site work
