San Juan's listing is built around a single property, The Outlets at Monteheidra on Camino Los Romeros, which alone accounts for 20 available office lots. Concentration of that kind means a tenant comparing options in San Juan is comparing 20 suites inside one managed building in the Cupey area, where parking, security and access terms are identical across every unit.
Available areas in San Juan run from 5 m² to 520 m², and the median suite is 60 m². The distance between that 60 m² median and the 520 m² top lot shows the address serving two tenant types at once: small professional practices taking a single room, and a company that needs a whole floor plate in San Juan without moving to a second building.
Rates in San Juan sit between $345 and $665 per m² a year, with the median at $390 — far closer to the bottom of the range than to the top. Most of the 20 San Juan lots are therefore priced near $390, and paying toward $665 buys something specific, such as frontage or a large contiguous area, rather than a general market premium.
Cost planning in San Juan is simpler than in a multi-building market: the $345 floor and the $390 median describe suites under one roof, so a quote well above $390 reflects the individual unit — its size or its position in the building — and can be checked directly against the neighbouring lots on the same list.
