Downtown White Plains
Westchester's largest office and retail center, with Class A office towers, the Westchester mall, medical offices and restaurants.
Westchester County
Corporate offices on the Platinum Mile, medical practices in White Plains and Valhalla, retail in Scarsdale and restaurants along the Hudson — commercial construction across Westchester.
Westchester County combines a major corporate office market with a large healthcare sector, busy downtowns and destination dining along the Hudson. Downtown White Plains is the county’s business center. The Platinum Mile along I-287 hosts corporate headquarters in Rye Brook, Harrison and Purchase. Valhalla is a major healthcare and medical education hub. And the Rivertowns, from Dobbs Ferry to Croton-on-Hudson, mix corporate campuses with village retail and restaurants.
Quedan Construction is a Westchester general contractor building offices, medical and dental practices, retail stores, restaurants and commercial kitchens across Southern, Central and Northern Westchester and the Rivertowns.
From Class A towers in White Plains to headquarters campuses on the Platinum Mile and in Armonk, we build corporate, financial and professional offices — coordinating landlord standards, campus rules and local permits.
Westchester’s health systems and private practices create steady demand for medical construction. We build physician practices, dental offices, imaging suites and specialty clinics in White Plains, Valhalla, Scarsdale, Rye, Mount Kisco and beyond.
We build stores in White Plains, Scarsdale, Yonkers and Port Chester, and restaurants and bars in the Rivertowns, Rye, New Rochelle and White Plains — with storefront approvals from local review boards built into the schedule.
Like Long Island, Westchester has no single building department. Permits are issued by the city, town or village where your project is located, under the New York State Uniform Fire Prevention and Building Code. Many villages also have architectural or historic review boards for storefronts and signage, and food service establishments are permitted by the Westchester County Department of Health. We map the approval path for your address before design begins.

Local know-how
Westchester permits are issued by the city, town or village where the project is located. Each has its own submission requirements, fees and review times.
Many Westchester villages require architectural or historic review for storefronts, signage and exterior changes — sometimes before a building permit can be issued.
Westchester projects follow the New York State Uniform Fire Prevention and Building Code and NYS Energy Code, not the NYC Construction Codes.
Food service establishments in Westchester are permitted by the Westchester County Department of Health, which reviews plans and inspects before opening.
