Clarkstown homeowners should check the town building route before a renovation becomes a half-finished problem. The town has a Building Department page and a building-permits page for additions, decks, accessory structures, and other property work. Before work starts, confirm the permit type, required plans, order of inspections, and certificate needed to close the file.
Buyers can use the same route to ask about finished basements or past additions. Ask the town before spending contractor money.
Check Clarkstown’s building-permit information against the renovation before signing a work contract. Keep the address, project description, application or permit number, inspection steps, and final certificate question with the job.
