Irvine holds the largest office listing in Orange County on this site — 299 units across 33 buildings — and the widest practical choice: rates run $286 to $714 per m² a year and units span 5 m² to 530 m², median 55 m². Addresses run from Spectrum Center Drive in the south to Von Karman Avenue and Alton Parkway in the business core.
Spectrum Center Drive sits beside the Irvine Spectrum retail district and carries the newest towers, at the upper end of the range. Von Karman Avenue runs through the Irvine Business Complex near John Wayne Airport — the traditional professional address, and the densest cluster in this listing. Alton Parkway and Murphy Avenue move inland towards the industrial-flex stock, where the rate falls toward the $286 floor and parking is generous.
Depth of choice is Irvine's real advantage: at almost any size between a single desk and a 530 m² floor there are several competing addresses within a ten-minute drive. That is unusual — most cities in this listing offer one or two options per size band. Each card shows the floor area, the floor and the asking rate per m² per year.
