A
General Engineering Contractor
Covers fixed works that require specialized engineering knowledge and skill — grading, drainage, paving, utilities, site work, and structural site preparation. This is the foundation for getting a property graded, drained, and ready to build on.
B
General Building Contractor
Covers structures built to support, shelter, and enclose people or property, where the work uses at least two unrelated building trades. This is the classification behind whole-home builds, additions, and major remodels.
C-9
Drywall
Covers laying out and installing gypsum wallboard and its assemblies — including non-structural metal framing — and the taping and texturing that produce a continuous smooth or textured surface ready for finish.
C-10
Electrical
Covers placing, installing, erecting, and connecting wires, fixtures, appliances, raceways, conduits, and solar photovoltaic systems — anything that generates, transmits, transforms, or uses electrical energy.
C-33
Painting & Decorating
Covers preparing surfaces — scraping, sandblasting, and similar prep — then applying paints, coatings, stains, textures, and papers to decorate, protect, fireproof, and waterproof.
All under one license
Holding these classifications together means fewer hand-offs between separate contractors, tighter coordination, and more speed — one accountable team moving the work from site prep through final paint.
