Doubts
FAQ’s
Do I need a permit for a home extension in Nassau or Suffolk County?
Yes. All structural changes, home additions, and dormers require building permits. TCR Builders handles the entire permitting and approval process for you, ensuring full compliance with local zoning laws and building codes.
How long does a second floor addition take to build?
While timelines vary based on the project’s exact scope, a standard second floor addition typically takes 3 to 5 months from the start of framing to the final inspection. We provide a detailed project timeline before construction begins.
Will a home addition increase my property taxes in Long Island?
Generally, yes. Adding square footage or new bathrooms increases your home’s assessed value. However, the exact increase depends on your specific town’s reassessment policies. The significant boost in your property’s resale value typically outweighs the tax adjustment.
Can you match the new extension to my existing home's exterior?
Absolutely. We carefully source siding, roofing materials, and windows to seamlessly blend the new structure with your home’s original architectural style, ensuring a cohesive and premium exterior finish.
