İşyeri Açma ve Çalışma Ruhsatı: the Baseline Municipal Licence

Almost any physical premises used for commercial activity in Turkey — an office, shop, workshop or restaurant — needs a workplace opening and operation licence (İşyeri Açma ve Çalışma Ruhsatı) issued by the local municipality, separate from your Trade Registry company registration. The municipality checks zoning compliance, fire safety, and, for certain activities, health inspection before issuing this licence, and operating without it can result in closure orders rather than just a fine.

Sector-Specific Additional Licences

Beyond the baseline municipal licence, specific sectors need additional approvals: food and beverage businesses need hygiene certification from the health directorate (see our restaurant licensing guide), construction and real estate development need zoning and building permits (see our construction company guide), and regulated professions (health, education, financial services) need approval from their respective ministry or regulatory board on top of the standard business licence.

Timeline and Common Delays

Licensing timelines vary significantly by municipality and sector, but a realistic expectation is several weeks to a few months for a straightforward retail or office premises, longer for food service or anything requiring fire department sign-off. The most common delay is a mismatch between the property's registered zoning use and your intended business activity — confirm the property's zoning classification before signing a lease, not after.

What Happens if You Operate Without the Right Licence

Operating without the required workplace licence can result in an administrative fine and, in more serious or repeated cases, an order to close the premises until the licence is obtained — this is a meaningfully different risk than simply being under-registered for tax purposes. If you are taking over an existing premises from a previous tenant, confirm whether the existing licence transfers to you or whether you need to reapply, since assumptions here are a common source of costly delays.
