General Construction & Additions in Chappaqua - Frequently Asked Questions
Can I Add Square Footage to My Chappaqua Home?
In most cases yes, given the hamlet's typically larger lots, subject to Town of New Castle zoning and setback rules we confirm during the feasibility check.

Zoning for Chappaqua is set by the Town of New Castle, since the hamlet isn't separately incorporated. We check the specific zoning district your property falls under before design work starts.
How Does Tree Cover Affect Construction in Chappaqua?
Mature trees can constrain equipment access and staging on wooded Chappaqua lots, which we plan around during project setup rather than discovering on-site.
