Permits & Licensing in Nassau County
Nassau County and its towns have their own permit and contractor-licensing rules. Structural work, additions, decks, and electrical or plumbing changes typically require permits, and that work is coordinated with licensed trades. Cosmetic updates like paint, flooring, and cabinets usually don’t. Always confirm your contractor is properly licensed to work in your town before signing a contract — it protects your home and your investment.
