Residential building and remodeling licensed at state level; local municipalities enforce the State Building Code. Only electrical work regulated at state level; all other trades regulated locally. State regulates electrical work for road construction and out-of-state contractors on contracts above **\$2,500**. Registration required for all construction exceeding **\$4,000** per project. Prequalification required for all highway work; no general state contractor license. State licensing required for electrical, plumbing, and asbestos abatement.
