Every guide here exists because a client asked the same question twice and the answers online disagreed. That pattern turns out to be the norm in UAE office and licensing questions: official pages publish the rule but not the price, consultancies publish the price but not the source, and comparison articles average the two into a figure nobody can stand behind.
So these guides follow one discipline. An official figure is labelled official. A market range is labelled a market range and names where it came from. Where sources genuinely contradict each other — the mainland minimum office size, the Ras Al Khaimah registration fee base, the free zone tax de minimis — the contradiction is shown rather than resolved, because resolving it would mean inventing a number.
Where to start
If you are early and the question is which structure, start with mainland versus free zone — it sets out what each route requires of the office itself and gives a decision sequence that holds up.
If the structure is settled and the question is how big, go to office space per visa. The 9 m²-per-visa ratio is the single number most downstream decisions depend on.
If you already know the shape and the question is how much, read Dubai versus Ras Al Khaimah for the floor-area gap and what a RAKEZ flexi desk costs for the packaged end of the market.
And if a bank or a landlord has already said no, the two operational guides are office requirements for a UAE bank account and tenancy registration in Ras Al Khaimah — the second of which starts by correcting the question, because Ejari is a Dubai system and does not exist here.
