Who’s behind it
Operated by Topside Real Estate
Topside is a boutique commercial brokerage in Newport Beach: twenty-five years in Orange County office, industrial, and retail, and over a thousand closed transactions on both the landlord and tenant side. That second part matters: when a Topside broker negotiates for you, they already know what the other side is going to do.
OC Office Space exists because the tools built for institutional investors were never built for the business that just needs 6,000 square feet in Irvine by spring. This one is.
