Koh Chang has a small, resort-driven office footprint in Trat province — almost no purpose-built commercial stock, a business base built around resort and villa-management administration, concentrated between White Sand Beach's tourist strip, Klong Prao's immigration and villa-management cluster, and Bang Bao's fishing-pier tour-operator scene. Builds on our national office overview. General information only, never paid placement.
Don't expect office towers, or even much purpose-built commercial space, on Koh Chang — the island's "office market" is almost entirely resort and villa-management back offices, concentrated in White Sand Beach and Klong Prao, with Bang Bao's stilted fishing pier serving as the base for tour-operator and boat-charter admin. A smaller, newer layer of real estate offices has grown alongside the island's limited low-rise condo development. The Ao Thammachat car ferry — Koh Chang's only active ferry route, since there's no airport on-island — keeps construction and fit-out costs high, reinforcing why almost nobody commissions new commercial stock here. The same Thai-entity, BOI or Treaty of Amity rules govern who can sign a lease as anywhere else in Thailand.
As a general pattern rather than a live quote, Koh Chang office and small commercial space sits below Koh Samui's already-modest market and roughly in line with Koh Lanta's — the island's small resort-driven economy, near-total lack of purpose-built stock and hotel-dominated tenant base leave essentially no formal Grade A/B benchmarking to point to. White Sand Beach space, where footfall and visibility carry a premium, generally costs more than equivalent space in Klong Son or Bang Bao. Because so much activity happens inside a working resort rather than a standalone office, "market rent" for Koh Chang is thinner and harder to benchmark than almost anywhere else covered on BAANLYY — always confirm actual figures with a commercial agent covering the Trat area before relying on any number on this page.
Koh Chang's defining commercial-real-estate pattern is that "office space" and "resort" are usually the same lease. A hotel's front desk, reservations system and staff back office typically sit inside — or directly behind — the same premises where guests check in, rather than in a separate leased unit. That keeps overhead low for small, owner-operated resorts, but it also means a lease for this kind of space is often a mixed hospitality-and-office arrangement rather than a standard commercial lease, and diligence on the space needs to account for the resort's own hotel-licensing and land-title standing (particularly near the Mu Ko Chang National Park boundary) alongside the usual lease terms — worth flagging to a lawyer reviewing any agreement.
Koh Chang has no airport of its own — the nearest is Trat, served by Bangkok Airways and about a 20-minute drive from the ferry piers. Everything arriving on the island, including construction materials and commercial fit-out equipment, ultimately crosses via the Ao Thammachat car ferry to Ao Sapparot pier, now the island's only active ferry route (running roughly 06:00 to 19:30 daily). That adds cost and lead time to any renovation or new build relative to airport-served markets like Koh Samui or Phuket, and it's a major reason so few operators invest in purpose-built commercial stock: it's simply cheaper and faster to adapt existing resort or villa premises than to commission something new. Anyone planning a fit-out or expansion on Koh Chang should budget extra time and freight cost for materials versus a mainland or airport-served-island project.
The company-structure requirements are the same as anywhere in Thailand: landlords typically contract with a registered legal entity, not an individual or an overseas parent company directly. That means having a Thai entity in place — a standard limited company under the Foreign Business Act, a BOI-promoted company where applicable, or (US nationals/companies only) a US-Thai Treaty of Amity certificate — before signing. No permanent law firm is confirmed on Koh Chang itself or in Trat town on the mainland, so most residents and businesses use a Pattaya-based firm covering the Trat area, or a Bangkok or Koh Samui firm serving Gulf-coast islands remotely. Given how much of Koh Chang's commercial stock is bundled into an existing resort or villa-management operation, many foreign entrepreneurs enter the market by buying into or taking over an existing business (including its premises) rather than negotiating a fresh commercial lease from scratch. Confirm your company structure and any sector restrictions with the Department of Business Development before committing.
