Plescia Construction & Development is a commercial general contractor and construction management firm building across Westchester County — delivering corporate office build-outs, healthcare and life-sciences space, retail, and the high-rise mixed-use redevelopment reshaping the county’s cities. Westchester is one of the strongest suburban commercial markets in the country, and we build to the standard its owners, corporations, and institutions expect.

Commercial Construction Across Westchester County

Westchester pairs a deep corporate economy with a major healthcare and life-sciences sector and a wave of downtown redevelopment. Downtown White Plains and the I-287 corridor anchor the office market; Westchester Medical Center, White Plains Hospital, and the Regeneron campus in Tarrytown anchor healthcare and biotech; and cities like New Rochelle and Yonkers are in the middle of some of the most active downtown development in the region. Each of these markets asks something specific from a contractor, and we build to it.

Our Westchester County work spans the full range of commercial space:

  • Office and corporate — build-outs and renovations in downtown White Plains, along the I-287 corridor, and in the corporate centers of Harrison, Purchase, and Tarrytown.
  • Healthcare and life sciences — exam suites, imaging, ambulatory space, and lab and life-sciences fit-outs serving the county’s major health systems and research campuses.
  • Retail and mixed-use — anchor and in-line retail and the ground-floor commercial in the county’s downtown redevelopment.
  • Restaurant and hospitality — kitchens, dining rooms, and hospitality space across the county.
  • Light industrial and flex — service, distribution, and flex space in Westchester’s commercial corridors.

Communities We Serve

We work throughout Westchester County — White Plains, Yonkers, New Rochelle, and Mount Vernon; Harrison, Rye, Rye Brook, and Port Chester; Tarrytown, Sleepy Hollow, and Greenburgh; Scarsdale, Eastchester, and Bronxville; Mount Kisco, Bedford, and the northern Westchester communities; and Peekskill and Ossining along the Hudson. Each city, town, and village brings its own building department and approvals picture, and we plan for it.

Permitting Across Westchester County’s Cities, Towns, and Villages

Westchester projects don’t run through the NYC Department of Buildings. Every commercial project answers to the building department of its city, town, or village, plus county and planning-board review — and a downtown White Plains high-rise, a corporate office in Harrison, and a Main Street storefront in a village each follow a different path. We manage the full route: building permits, site plan and planning-board review, and the inspections that keep a project moving.

Several requirements shape commercial work here:

  • City, town, and village building departments — the Cities of White Plains, Yonkers, New Rochelle, Mount Vernon, Peekskill, and Rye, plus the county’s many towns and villages, each run their own permitting and inspections.
  • Site plan, planning-board, and zoning review — ground-up and larger commercial projects go through site plan, planning-board, and often zoning-board review, with downtown overlay zones in cities like New Rochelle shaping the process.
  • Westchester County health and environmental approvals — water, sanitary, and environmental review at the county level, with State Environmental Quality Review (SEQRA) on larger projects.
  • New York State code and fire safety — work is built to the New York State Uniform Code, with local fire marshal review for life safety.

Knowing each city’s process — and its development incentives — is what keeps a Westchester project on schedule.

How We Manage Risk on Westchester County Projects

From a downtown high-rise fit-out to a corporate office renovation or a medical build-out, the same discipline applies: plan the site and the approvals realistically, protect the businesses and traffic around the work, and keep life-safety systems live throughout. We coordinate deliveries, phasing, and logistics with owners and tenants, and we carry the insurance limits and trade relationships that Westchester owners, corporations, and institutions expect.

Every job runs through a single point of accountability. Owners, tenants, building departments, and the design team work through one team that owns the schedule, the budget, and the safety plan — not a chain of subcontractors pointing at each other.

Representative Commercial Work

Plescia’s portfolio spans office, healthcare, retail, and mixed-use work of the kind Westchester County demands. While every market has its own specifics, the discipline is the same one we bring to projects across our New York, New Jersey, Florida, and Texas markets: realistic schedules, transparent budgets, and a finished space that performs. We’re glad to walk prospective Westchester County clients through relevant past work during an initial conversation.
