Every office listing in the district on 10 August 2026 puts the mainstream asking range at AED 1,850–2,935/ft² with asking rents of 145–263 AED/ft²/year, implying a gross band of 6.1–11.2% on asking-over-asking arithmetic. The broker estimate from a named research note is 7–9% gross (Chestertons, February 2026). Both describe the mainstream. Neither describes the top of the market.
The trophy towers are a different asset. Business Bay's landmark offices ask 5,500–7,350 AED/ft², which takes the gross yield down to 4–5% — below the average Dubai apartment. Which is the thing to hold on to here: inside one postcode the yield runs from better-than-an-apartment to worse-than-one, decided entirely by which tower you pick.
And the cheapest units here are the most expensive per foot. The sub-AED-1M offices in Business Bay are micro-lots in older towers — 221–230 ft² asking 2,805–2,935/ft², 282–440 ft² asking 2,159–2,725/ft². You are paying for the address and for the divisibility, not for area. They let well, though: in one of those towers a fully furnished 440 ft² unit asks 250 AED/ft²/year against an unfurnished 407 ft² unit in the same building at 164 — a 52% premium on the rate, which is one of the few places in Dubai where the fitted premium is real. The full set of seven same-building pairs, including the three where the premium is zero or negative, is in Grade A Offices: What Supports a Rental Premium.
Two running costs come with the office, and neither shows up in the headline price. Service charge: 15–20 AED/ft²/year for Business Bay — and that is a Mollak residential proxy, because no public service-charge index exists for offices; the rate for a specific building is public in Mollak, per project. Fit-out: for Business Bay specifically, 214–284 AED/ft² light, 284–374 standard, 374–524 premium (TR Design Build, updated July 2026), with a 40–60% uplift on a basic fit-out when starting from shell & core. Lumena and Haus of Tenet are sold shell & core, so for them that uplift is part of the entry price, not an option; HQ by Rove is the district's exception, selling fitted and furnished.
