What it freezes is a specific list: the conversion of a construction servitude into freehold condominium ownership, the ex officio change of the property's registered class, and the utility connections of the units that lack it. This guide separates the administrative consequences from the myths and shows where the shortfall turns into a defect claim.
In Türkiye an apartment with no occupancy permit (yapı kullanma izni, commonly “iskân”) can still be sold, but three things cannot be done: freehold condominium ownership (kat mülkiyeti) cannot be established, because Article 12(a) of Condominium Law No. 634 lists the permit among the documents to be filed with the land registry; the property’s registered class is not changed ex officio; and under Article 31 of Zoning Law No. 3194 the building is not supplied with electricity, water and sewerage until the permit is obtained, although independent units that hold a permit are supplied. The municipality or governorate must decide a permit application within 30 days under Article 30, failing which use is deemed permitted. A building erected in conformity with a construction permit obtained by 1 July 2022 (for buildings constructed before 31 December 2021 the permit condition does not apply) may receive a temporary water and electricity connection under Provisional Article 11 of the same Law, which creates no acquired right.
A missing occupancy permit in Türkiye does not stop you buying the apartment, and it does not by itself make the building unlawful. What it stops is a short, specific list of transactions: the conversion of a construction servitude into freehold condominium ownership, the ex officio change of the property’s registered class, and, for the units that lack it, the electricity, water and sewerage connections. Everything else that is commonly said about the yapı kullanma izni is either a consequence of those three, or is not in the legislation at all. This guide separates them, reading Articles 30 to 32 of Zoning Law No. 3194 alongside Articles 3, 10, 12 and 14 of Condominium Law No. 634. The position is stated as at October 2026.
What is an occupancy permit (yapı kullanma izni) in Türkiye?
Article 30 of Law No. 3194 sets a use prohibition, not a formality. Where a building is completely finished, permission is required for the whole of it; where parts capable of separate use are finished, permission is required for those parts. The application is made by the owner, and the administration that issued the construction permit, the municipality or the governorate, must establish two things before granting it: that the building conforms to the permit and its annexes, and that there is no technical objection to its use.
Two features of the article are usually missed. The first is a deadline running against the administration: municipalities and governorates must conclude an owner’s application within thirty days, failing which use of the building, or of the finished part, is deemed permitted at the end of that period. The second is the sentence that closes the article, and it cuts the other way: a permit granted under Article 30 does not release the owner from liability arising out of failure to comply with the Law and with the permit and its annexes, nor from any obligation to pay taxes, duties and fees. The occupancy permit is a use authorisation. It is not an amnesty, and it is not a certificate of legality.
Article 31 then supplies the definition that drives most of the commercial consequences: the completion date of the construction is the date the use permit is granted. Until that date, in the eyes of the zoning legislation, the building is not finished, however habitable it looks.
Which transactions are blocked without an occupancy permit?
The blocked list is short and it is registral before it is practical.
| Transaction | Position without an occupancy permit | Source |
|---|---|---|
| Sale and transfer of title of the unit | Not blocked. A construction servitude over a land share is transferred in the ordinary way, together with the land share | Law No. 634, Arts. 14 and 5 |
| Establishing freehold condominium ownership (kat mülkiyeti) | Blocked. The occupancy permit is one of the documents that must be filed with the land registry | Law No. 634, Art. 12(a) |
| Converting an existing construction servitude into freehold ownership | Blocked. Conversion is ex officio, but only on the basis of the permit issued for the whole building | Law No. 634, Art. 3/3 and 10/6 |
| Change of the registered class of the property (cins değişikliği) | Blocked. The ex officio procedure is triggered by the permit being uploaded to the Spatial Address Registration System and sent to the cadastre office | Law No. 634, Art. 10/6 |
| Electricity, water and sewerage in the unit's own name | Blocked for units without a permit; available for units that have one | Law No. 3194, Art. 31 |
| Curing the position for your apartment alone | Not possible. Freehold ownership cannot be established over one or several sections without converting the whole immovable | Law No. 634, Art. 10/2 |
The first row is wider than most buyers expect. Article 14 of Law No. 634 frames the construction servitude as one created over land on which no building has been erected or whose building has not been completed; it is nevertheless a right entered in the land register, and Article 5 fixes how closely it is tied to the land share by forbidding that share to be transferred, inherited or encumbered separately from condominium ownership or from the construction servitude. A delayed permit therefore does not reduce the buyer to a possessor without title. What it does is freeze the character of the right at a servitude attached to a land share and postpone the moment when the unit appears in the register as an independent immovable. The security structure stays in the same place: a mortgage taken by a lender sits on the construction servitude until the conversion happens.
The registral entries deserve emphasis, because they explain why a delayed permit is felt years later. Article 10/6 of Law No. 634, as amended in 2021, makes both steps automatic once the permit exists: the class change of every building for which an occupancy permit is issued is carried out ex officio, the authority competent to issue the permit uploads it to the Spatial Address Registration System (Mekânsal Adres Kayıt Sistemi) and sends it electronically to the cadastre office, which prepares the registration notice from the permit and the building application project, the land registry records the change without seeking any further document, and where the immovable already carries a construction servitude, that servitude is converted into freehold condominium ownership ex officio on the basis of the original deed and the Article 12 documents, free of the revolving-fund service fee. Article 3/3 adds that a single land owner, or any one of the co-owners holding a construction servitude, can trigger the conversion. The whole machine is built to run by itself. The permit is the switch.
Can a flat without an occupancy permit get electricity and water?
Article 31 is the provision most often quoted and most often quoted incompletely. It provides that buildings for which a use permit has not been granted and has not been obtained are not supplied with electricity, water and sewerage services and installations until the permit is obtained. The next sentence, in the same article, then provides that independent units which have obtained the use permit are supplied with those services.
That exception is the practical route out for an individual apartment. Read with Article 30’s rule that finished parts capable of separate use may be permitted separately, it means the question to put to the municipality is not “when will the block be signed off” but “can this unit be signed off now”. A partial permit for the completed section restores that unit’s subscriptions even while the rest of the site remains open.
A separate, temporary route sits in Provisional Article 11 of Law No. 3194, added in 2008 and amended by Law No. 7417 in 2022. For a building that was erected in conformity with a construction permit obtained by 1 July 2022 but has no occupancy permit, water and/or electricity may be connected temporarily on application, within the subscriber group defined for it, where it is documented that one or more infrastructure services (road, electricity, water, telephone, sewerage, natural gas) have been brought to the building and the technical requirements of the relevant regulations are met. For buildings constructed before 31 December 2021 the condition of a construction permit and conformity with it does not apply. The connection creates no acquired right: if the municipality asks the distribution company to cut the electricity, the subscription is cancelled. Article 31 itself lists only electricity, water and sewerage; it does not mention natural gas or telephone lines.
One further gate is independent of zoning law altogether. Article 11/3 of Disaster Insurance Law No. 6305 requires the relevant undertaking to verify that compulsory earthquake insurance is in place when water and electricity subscriptions are made for buildings and independent units within the scheme, and Article 11/2 stops the land registry from carrying out registration or deletion transactions unless valid cover is evidenced at the date of the transaction. A buyer working through a stalled building therefore has two documents to track, not one.
Missing paperwork or an unlawful building?
This is the distinction that decides how serious the file is, and it is the one most often blurred in listings. The enforcement machinery is in Article 32, and it is triggered by construction started without a permit, or carried out contrary to the permit, its annexed studies and projects, or the zoning legislation. Where that is detected, the building is sealed and work stops immediately; since the 2020 amendment, the administration must notify the land registry in writing within seven days so that the non-conformity is recorded in the declarations column of the title register, and that record cannot be removed until the administration notifies that the breach has been cured. The owner then has one month to bring the building into conformity or obtain a permit; failing that, the construction permit is cancelled and the building is demolished by resolution of the municipal committee or the provincial administrative board, with the cost recovered from the owner.
None of that follows from a building that was constructed in accordance with its permit and whose owner simply never applied for sign-off. The administrative fines in Article 42 point the same way: they are imposed on buildings constructed without a permit or contrary to the permit and its annexed studies, projects and the zoning legislation. Occupation aggravates rather than creates liability, where the works are complete and the building is not in use the fine is increased by 10 per cent, and where it is complete and in use by 20 per cent. The lira figures in Article 42 are the nominal amounts in the enacted text and are increased each calendar year by the revaluation rate under repeated Article 298 of Tax Procedure Law No. 213, so any current figure must be taken from the year’s announcement rather than from the statute.
For a buyer, the practical test is therefore: read the declarations column of the title register first. An Article 32 annotation converts an administrative delay into a legal defect with a demolition file behind it, a materially different purchase from an unsigned-off but compliant block, and the point at which the general due-diligence sequence for foreign buyers needs to be widened rather than repeated. Where the permit or register extract shown by the seller does not match the municipality’s file, the issue is no longer zoning but the remedies covered in the note on real-estate fraud and title cancellation.
The Building Registration Certificate, and why it is not a route in
Provisional Article 16 of Law No. 3194, the 2018 zoning settlement, is still offered as a solution. As a fresh application it no longer exists: it required the building to have been constructed before 31 December 2017, the application to be made to the Ministry or an authorised body by 31 October 2018, and the registration fee to be paid by 31 December 2018.
What matters now is a certificate already in hand, and it does two things. First, buildings holding one may, on request, be connected temporarily to water, electricity and natural gas, taking into account the subscriber group defined for them in the relevant legislation, a discretionary and provisional connection, not the permanent supply that follows an occupancy permit. Second, and more significantly, the fifth paragraph allows the class change and the establishment of condominium ownership without an occupancy permit for buildings that took a construction permit but never obtained sign-off, and for buildings with no construction permit at all, on three cumulative conditions: the consent of all owners, the surrender of areas corresponding to public service zones on the zoning plan, and payment of twice the registration fee.
The limits are written into the article. The certificate is valid only until the building is rebuilt or an urban transformation scheme is applied, and current zoning legislation governs any renewal. The provision does not apply within the mapped Bosphorus shoreline and foreground zone, the mapped area of the İstanbul historic peninsula, or the Gallipoli Historic Area. And buildings standing on immovables owned privately by third parties are excluded from the article altogether.
When does a missing permit give the buyer a claim against the seller?
Where the shortfall was not disclosed, it is a legal defect and the standard warranty analysis applies to it. Article 219 of Turkish Code of Obligations No. 6098 makes the seller liable for material, legal or economic defects that destroy the value of the property for its intended use or materially reduce the benefits the buyer expected from it, and the following sentence states that the seller is liable even without knowing of them. Article 8/2 of Consumer Protection Law No. 6502 treats legal shortfalls the same way, and adds that a good is defective where it lacks features stated in advertising or on an internet portal, which is how a listing promising “iskânlı” delivery becomes contractual content.
The remedies are four in both regimes: rescission on declaring readiness to return the property, price reduction in proportion to the defect, free repair unless it requires excessive expense, and replacement with a defect-free equivalent where possible, with damages reserved under the general provisions (Article 227 of Law No. 6098; Article 11 of Law No. 6502). For a home, free repair or replacement must be delivered within sixty working days of the request under Article 11/4, the thirty-working-day figure belongs to movables. In practice the elected remedy for a stalled permit is usually price reduction or damages, because “repair” here means completing an administrative process the seller may not control.
On timing, Article 244/3 of Law No. 6098 gives five years from the transfer of ownership for claims arising from a building being defective, and twenty years where the seller is grossly at fault; Article 231’s general two-year rule is displaced. Where the defect is traced to the contractor’s work rather than the seller’s disclosure, Article 478 runs five years from delivery for immovable structures and twenty on gross fault, the sequence set out in the companion note on warranty and limitation periods for construction defects. For a consumer buying a home, Article 12 of Law No. 6502 gives five years from delivery and Article 12/3 disapplies limitation entirely where the defect was concealed by gross fault or fraud.
Two counterweights belong in the same paragraph. Article 10/1 of Law No. 6502 presumes that defects appearing within six months of delivery existed at delivery, unless the presumption is incompatible with the nature of the goods or of the defect. But Article 10/2 provides that there is no non-conformity where the buyer knew of the defect, or could be expected to have known of it, when the contract was made, so a purchase contract in which the buyer acknowledged the missing permit will be put in front of them. Where the claim proceeds, the forum and procedure questions are set out separately in the note on bringing a claim against a developer in the consumer courts, and the transactional side sits with our real estate law work.
The short version
The occupancy permit is a switch, not a wall. Turning it on releases the class change, the automatic conversion to freehold condominium ownership and the permanent utility connections, all of which the legislation is drafted to perform ex officio the moment the document exists. Leaving it off does not void the sale, does not by itself make the building unlawful, and does not necessarily cut a particular apartment off from electricity and water. What it does is hold the register in a provisional state that no individual owner can exit alone, and that is the reason to establish, before signing, exactly what stands between the building and Article 30.
