A building permit (Yapı Ruhsatı) is tied to a particular project, parcel, scope and time. For a buyer, checking only that “a permit exists” is insufficient. The permit must belong to the property under review, cover the relevant construction or alteration and still be meaningful in light of later amendments, renewals, completion and occupancy records. Deadline control means tracking the permit’s dates and subsequent official actions so that an old or superseded permit is not presented as proof of the building’s current legal condition.
Identify the permit precisely
Record the competent municipality or authority, permit number, issue date, parcel identifiers, building/block and stated construction scope. Compare these with current TKGM cadastral data and the unit being purchased. If the seller gives a photocopy that lacks annexes or project references, obtain enough official information to establish what the permit actually authorised. A permit issued for the same parcel but for another block or an earlier phase cannot automatically be applied to the target unit.
Track amendments and later permits
Buildings may have amendment permits, renovation permits or updated approved projects. Create a chronology rather than treating the first permit as the whole story. Identify any change that affected floor count, use, common areas, façade, structural system or independent-unit arrangement. If the physical building differs materially from the project relied on, escalate to the municipality or qualified professional. The transaction file should identify which permit and project version represents the present building.
Separate permit status from occupancy
Yapı Ruhsatı authorises construction; Yapı Kullanma İzin Belgesi addresses use after completion. One should not be used as a substitute for the other. A building can have a historic construction permit while questions remain about completion, alterations or occupancy. For new or recently completed property, cross-check the EKB and occupancy documentation where applicable. The buyer should know whether the review concerns authorised construction, authorised use, or both.
Control timing before payments
When a purchase depends on completion of a permit-related correction or revised approval, tie major payments to receipt of the official evidence. Record the responsible authority, expected document, target date and consequence if the deadline is missed. Do not accept a developer’s statement that a revision is “in process” as equivalent to an issued approval. If construction continues, obtain a current status close to each major payment milestone.
Closing-day refresh
Before transfer, confirm that no new municipal notice, amendment, cancellation, enforcement action or project change has arisen after the earlier review. Save the date and source of the final check. Stop if the permit identifiers cannot be reconciled with the parcel or building, if a material physical change has no clear approval basis, or if the transaction depends on a future permit that has not yet been issued. A robust file allows a later reviewer to see the complete permit timeline and the exact official evidence on which the buyer relied.
Treat permit status as date-specific evidence
A building permit can be amended, renewed, superseded or affected by later works. Record the permit number, issuing authority, relevant dates and the property identifiers used to match it. If the file contains an amendment, determine whether it supplements the original permit or replaces part of the approved work. Do not rely on a photocopy whose relationship to the current building cannot be established. A long gap between technical review and closing should trigger a fresh municipal check where the risk justifies it.
Deadline control also means separating permit validity from completion or occupancy. A valid construction permit does not by itself prove that the building was completed in accordance with the approved project, and an expired period does not automatically tell you the legal status of works already performed. Those questions require the relevant municipal record and, when necessary, technical/legal review. The transaction file should state exactly what the permit evidence proves and what remains outside its scope, so a date label is not used as a substitute for substantive compliance analysis.
