White Plains IT Market Overview
The White Plains IT Market in 2026
A Head-Office County, With a Number Behind It
The sector that literally counts corporate head offices is NAICS 55, management of companies and enterprises. Westchester runs it at 1.31 times the national concentration, 9,488 jobs across 298 establishments at an average annual pay of $204,395. The downtown 10601 ZIP code alone holds 31,532 employees. This is a market of corporate functions, professional services and regulated data, and it prices accordingly.
Healthcare Is the Largest Employer, and It Is Building
White Plains Hospital reports more than 5,300 employees organisation-wide and calls itself the largest employer in Westchester County. It broke ground in May 2025 on an estimated $750 million expansion taking it from 292 beds to 436 by 2028. NewYork-Presbyterian's behavioural health centre and Burke Rehabilitation are also in the city. Healthcare runs at a location quotient of 1.30 countywide.
Offices Are Emptying and Becoming Housing
White Plains carries the highest office rents in Westchester, $34.54 overall and $37.89 for Class A, alongside vacancy in the low twenties. The response has been conversion rather than re-letting: a 350,000 square foot former AT&T control centre became 245 apartments, the Galleria mall is to be demolished for a mixed-use scheme, and the New York Power Authority is moving into a new tower while considering disposing of its 417,000 square foot building on Main Street. For an IT buyer that means a lot of local offices are moving, shrinking or being fitted out.
