Permits and sales tax in New Jersey
In New Jersey, work that touches structure, electrical, plumbing or mechanical systems generally needs a permit from your town's construction office under the NJ Uniform Construction Code. We prepare the drawings, file the permit and schedule the building, electrical and plumbing inspections.
New Jersey treats most permanent home improvements as capital improvements, which are exempt from sales tax on the labor when the homeowner signs Form ST-8. We give you the form with your contract.
