Take Advantage of NYS Grants & Local Tax Exemptions

Building an Accessory Dwelling Unit in the Mid-Hudson Valley has never been more financially advantageous. Between state funding programs and municipal tax incentives, eligible property owners can significantly offset construction costs while adding long-term equity to their homes.

  • NYS Plus One ADU Program: Eligible homeowners across Dutchess, Ulster, Orange, and Putnam counties can access up to $125,000 in state grant funding to build or convert fully compliant secondary units.

  • Local Property Tax Exemptions (RPTL § 421-p): Protect your investment. Recent New York real property tax laws allow participating municipalities to offer phased tax exemptions on the added value of newly constructed ADUs.

Troy Construction handles the full technical execution—ensuring your design, utility hookups, and building plans meet all local municipal codes required for grant and tax incentive compliance.

From Initial Feasibility to Turn-Key Handover

Constructing a detached cottage or garage apartment requires navigating strict local zoning, setback requirements, and utility capacity. Troy Construction manages every phase under one roof, keeping your project on schedule.

  • Zoning & Feasibility Assessment: We analyze your lot dimensions, setbacks, water/sewer capabilities, and local municipal bylaws across Dutchess, Ulster, Orange, or Putnam counties.

  • Architectural Design & Permitting: Custom layouts tailored to your property, engineered for energy efficiency and submitted directly for local building department approvals.

  • Master Construction & Utility Integration: Vincent Troy directly oversees foundation work, framing, plumbing/electrical tie-ins, and luxury interior finishes.
