Source Freshness Review — Building Permit Status
A building permit (yapı ruhsatı) is an official permission document issued by the competent administration after the required documents and projects are approved. For due diligence, the important question is not simply whether a permit once existed. The source-freshness review asks whether the permit status being relied upon still describes the project and parcel on the date of the transaction decision. A genuine historic permit may be stale if a later amendment, re-permitting event, lapse, parcel change or project revision has altered the current administrative position.
Start with the competent administrative record
Record the permit number and date, the issuing municipality or other competent administration, the parcel identifiers, the building/project description and the approved-project version connected to that permit. The Ministry’s guidance on permit and occupancy processes describes the building permit as an approved official permission issued by the relevant administration after the prescribed documents and projects are approved; it also notes that the permit is issued for the parcel. That makes parcel identity a core freshness control. A permit from the correct developer but the wrong parcel is not acceptable evidence for the asset under review.
The current record of the issuing administration should control the answer to “what permit is in force now?” A seller’s PDF, architect’s archive or old municipal receipt may help reconstruct history, but should not be treated as proof that no later administrative action occurred. Where the relevant municipality offers an electronic service through e-Devlet or its own system, use it within its stated scope; otherwise obtain the current information from the competent unit. TKGM Parcel Query can help check parcel identity, but it does not by itself establish building-permit validity.
Freshness is event-driven
A permit should be revalidated whenever the project has been amended, the parcel has been divided or consolidated, construction has stopped for a long period, a new permit or tadilat ruhsatı is mentioned, the building’s use or key physical parameters change, or the file contains a later municipal decision. Also refresh the review when a contract, valuation report, technical report or marketing material quotes a permit number/date that differs from the administration’s current record.
Current regulations matter because permit consequences can change. On 1 July 2026 the Ministry announced amendments to the Planned Areas Zoning Regulation, including clarified rules for re-permitting buildings whose permits became ineffective. The announcement states that a building whose permit has become ineffective must obtain a new permit under the applicable framework, with different treatment depending on whether construction began within two years of the original permit date. A review after that change should not rely on an older procedural summary without checking the current regulation and the project’s facts.
Do not confuse permit with occupancy permission
A building permit authorizes construction within its approved scope; an occupancy/use permission (yapı kullanma izin belgesi) concerns completion and use of the completed building. One does not substitute for the other. A building may have a historic building permit but require separate review of whether construction followed the approved project and whether an occupancy permit was issued. Likewise, utility connections, tax records, physical occupation or the age of the building do not independently prove that the building permit is currently valid.
Build a freshness timeline
For each controlling event, preserve the date, issuing authority, document number and link to the parcel. The timeline should start with the original permit, then record each amendment or replacement permit, project revision, formal extension/re-permitting event where applicable, and finally the current administrative confirmation obtained for the transaction. If there is a gap—for example, a seller shows a 2018 permit and a 2025 architectural revision but no corresponding administrative amendment—do not fill the gap by assumption. Record it as unresolved and request the competent evidence.
Project and parcel reconciliation
The permit should be tested against the approved project and current parcel identity. Confirm the same ada/parsel, address and building context. If cadastral identifiers changed, reconstruct the parcel history instead of forcing a visual address match. If the project changed, compare what the new permit or amendment actually authorized: floor count, building area, use, number of independent sections or other relevant parameters. The freshness question is not whether the building “looks similar” to the permit, but whether the current administrative record and the project relied upon are the same legal/technical version.
Decision consequences of stale evidence
A stale permit status can distort valuation, finance assumptions, construction-completion risk, redevelopment expectations and closing conditions. For an off-plan or incomplete project, uncertainty about current permit status can be especially material because the buyer is relying on future lawful construction. For an existing unit, the permit remains relevant to the building history but must be assessed together with occupancy permission, approved project and any later alterations. If the permit has become ineffective or requires re-permitting, do not convert that into a generic “minor paperwork issue”; determine what work can lawfully continue, what current rules apply, and what cost or timing consequence follows.
Closing standard
Close the source-freshness review only when the file identifies the current permit number/date, issuing authority, parcel, approved project version, later amendments or replacements, the date of the latest official verification and any unresolved issue. The conclusion should state “current permit status confirmed as of [date]” or precisely identify the gap. A long article, a scan bearing a municipal logo, or the existence of an old permit number does not satisfy this test.
