Cranford's office supply in this catalogue is highly concentrated: 2 buildings and 17 units, with Commerce Drive accounting for the addresses. That concentration is the first thing to plan around, because a tenant in Cranford is effectively negotiating with one of two landlords and the alternatives inside the township are limited to whatever those 17 listings hold at the time.
The Cranford units run from 5 to 172 m² with the median at 64 m². A 64 m² suite houses roughly eight to twelve people once meeting space is carved out, and the 172 m² top end is the only route in Cranford to a whole-floor tenancy without splitting operations between the 2 buildings.
Quoted rents in Cranford span $265 to $450 per m² a year with a median of $314, and across just 2 buildings that band reflects a serviced-versus-conventional split rather than any location premium. What the $314 median actually buys in Cranford is access — a Raritan Valley Line station in the township and the Garden State Parkway on its edge — so the case for the address rests on commuting reach across Union County, not on a downtown setting.
A Cranford search is best started from the 172 m² ceiling: if the requirement is larger, the 2-building supply cannot serve it and the fallback is combining units within one address. If the requirement is 64 m² or below — the Cranford median — the 17 listings give enough choice to push on lease term and fit-out contribution instead of arguing over the headline rate.
