Between Bursa and Yalova, which spa districts have the most foreign-owned thermal residences and what usage rules apply?

If you are comparing Bursa and Yalova for thermal property, the focus points are clear: Çekirge and Oylat in Bursa, and Termal and Armutlu in Yalova, because these are the officially designated thermal tourism districts where purchase activity by foreigners is concentrated within each province. Official statistics confirm that both provinces attract foreign buyers overall, but Turkey does not publish a district-level breakdown of “foreign-owned thermal residences,” so comparisons rely on where thermal tourism districts are located and where foreign purchases are recorded at the provincial level. In practice, most foreign-owned thermal homes in this corridor cluster around Yalova’s Termal and Armutlu, and Bursa’s Çekirge (Osmangazi) and Oylat (İnegöl), which are the main state-designated thermal tourism areas. [1][2]

Where foreign-owned thermal residences cluster in Bursa and Yalova

Turkey’s Ministry of Culture and Tourism formally designates “Culture and Tourism Protection and Development Regions” and “Tourism Centers,” including thermal tourism centers, and these designations define where thermal resorts and associated residences can be developed. In Bursa, Çekirge (within the central district of Osmangazi) and Oylat (in İnegöl district) are recognized thermal tourism areas. In Yalova, the Termal district and Armutlu district are designated thermal tourism centers. These four are the principal spa districts for residential development tied to thermal facilities in the two provinces. [2][6]

While Turkey’s statistical agency does not provide a count of foreign-owned properties by district or by property subtype such as “thermal residence,” it does publish annual and monthly house sales to foreigners by province. In these series, Yalova and Bursa have consistently appeared among the top provinces for foreign purchases in recent years, indicating active cross-border demand in both markets. For example, TurkStat’s “House Sales Statistics” show that both provinces recorded measurable sales to foreign nationals during 2022–2024, with Yalova often ranked among leading destinations relative to its population size. These are the same provinces that contain the above thermal districts, which is why these districts are the logical places where foreign-owned thermal residences are concentrated. [1]

The presence of officially designated thermal tourism centers is relevant because such designations influence zoning, investment licensing and facility permitting. In Yalova, the Termal and Armutlu thermal tourism centers are long-established spa localities with licensed bath complexes and resort developments. In Bursa, Çekirge’s historic hot springs and the Oylat area’s spa infrastructure are similarly protected and promoted under the tourism framework. These formal designations, rather than informal marketing labels, are the dependable way to identify where thermal residences can legally exist at scale in each province. [2][7]

Legal basis for foreign ownership and where it applies

Foreign real persons may acquire real estate in Turkey under Article 35 of the Land Registry Law No. 2644, subject to national security restrictions, the district-level 10% area cap, and the nationwide maximum of 30 hectares per person. These rules apply uniformly to Bursa and Yalova. The acquisition is processed by the Land Registry Directorate, and ownership confers the same condominium rights and obligations as for Turkish citizens unless a special restriction is annotated on the title deed. [3]

The development and classification of thermal tourism properties are governed by the Tourism Encouragement Law No. 2634 and related secondary legislation. If a project is licensed as a tourism accommodation facility or is within a tourism center, the land-use and building function are specified in the zoning and in the facility’s license. A residence located within a plot designated for tourism accommodation may carry operational constraints compared with a standard dwelling, especially on how it can be occupied or rented. These constraints come from the facility license and zoning status, not from the nationality of the owner. [6]

Separately, thermal spa operations are regulated under the Spa Regulation (Kaplıcalar Yönetmeliği) issued by the Ministry of Health. This regulation covers the authorization, classification, and health and safety requirements for the use of thermal waters and the operation of spa facilities. Where a “thermal residence” is integrated with a licensed spa complex, the operation of the spa component must comply with this regulation, and property owners are bound by the facility’s operating rules that flow from the license and the management plan. [7]

Usage rules that typically apply to thermal residences

Three legal layers shape how a thermal residence can be used in Çekirge, Oylat, Termal, or Armutlu. First, if the unit is a standard apartment under the Condominium Law No. 634, the owner enjoys full residential use subject to the management plan and must contribute to common expenses; failure to pay allows the management to pursue statutory remedies. These obligations and rights are identical for foreign and Turkish owners. [4]

Second, if the property is structured as timeshare, Turkish law treats this as a “timeshare right” (devre mülk hakkı) under Articles 57 to 60 of the Condominium Law. The timeshare deed specifies the periods during which each holder has the right of use; these periods are typically set in weeks, are recorded in the land registry, and are governed by the site’s management plan. Timeshare holders must pay proportional common charges and comply with facility rules during their allocated time. Transfers of timeshare rights follow the same formalities as real property transfers, including registration and, where applicable, notarial instruments. [4]

Third, if the unit is rented out, tourism-oriented short-term rentals are regulated by Law No. 7464 on the Tourism-Oriented Rental of Residences. As of 2023, offering a dwelling for short stays of fewer than 100 days requires a permit from the Ministry of Culture and Tourism and the display of a permit plate; the law also imposes administrative fines for non-compliance. Where the residence is located in a building or site with a tourism function, additional rules in the management plan or the facility’s license may apply, including limitations on daily rentals or requirements for guest registration. These rental rules apply equally in Bursa and Yalova. [5][6]

Where a thermal residence is part of a licensed spa or accommodation facility, owners may be required to adhere to health, safety, and hygiene protocols stemming from the Spa Regulation and the facility’s operating license, especially for shared thermal pools, treatment areas, and water usage. Site management may enforce hours of use, medical screening requirements set by the health authority, and technical rules on water handling, because these are conditions of the operator’s license under the Ministry of Health’s regulation. These conditions relate to facility operations rather than to land ownership, but they affect how owners and guests can use the thermal amenities. [7]

What this means for choosing between Bursa and Yalova

There is no official dataset ranking “which spa district has the most foreign-owned thermal residences” in a precise numerical sense, because Turkey’s public statistics report by province and do not break down foreign ownership by district or by specialized property subtype like “thermal residence.” However, if your search is limited to the established thermal districts in these provinces, the relevant Bursa districts are Çekirge (Osmangazi) and Oylat (İnegöl), and the relevant Yalova districts are Termal and Armutlu. These are the legally recognized thermal tourism centers, and they are situated in provinces that record ongoing foreign purchases. Due diligence should therefore focus on title annotations, zoning status, whether the project is residential, timeshare, or tourism accommodation, and the applicable rental and spa-operations rules. If you are planning a purchase for investment or mixed personal use, seek advice from a licensed attorney and tax adviser, as this information is general and your specific situation may differ.
