Urban Renewal by Simple Majority: 15 Days

If unanimity cannot be reached on a risky-building parcel, the new development can be decided by owners holding a simple majority by shares. A dissenting owner’s share is not put up for sale merely because the owner voted “no”.

This guide was prepared on 25 October 2026. It is not a new legislative announcement. It explains the current process following the regulation of 6 February 2024 together with the notification forms published by the Urban Transformation Presidency on 4 February 2026.

Simple majority is not a headcount

Under the Presidency’s current process guidance, the majority is calculated by ownership shares, not number of owners. Six signatures in a ten-unit building may therefore not prove the result. Land shares in the title register and the aggregate share of participating owners must be checked together.

A “no” vote does not trigger an automatic sale

The decision and the offer containing the agreement terms must be duly notified to a non-participating owner, including where the offer can be inspected. A share sale is based not on disagreement alone but on a valid decision, offer, notice and failure to accept within the prescribed time.

When does the 15-day period run?

Official guidance allows notice through a notary or by posting at the relevant neighbourhood headman’s office for 15 days. If the non-participating owner inspects yet does not accept within that period, the sale process may arise. The method, start and end dates, and delivery or posting records should be retained.

Sale is a separate administrative stage

Expiry of the period does not itself transfer the share. An application to the competent authority, file and notice review, valuation and sale/auction steps follow separately. The Presidency’s guidance points to district municipalities in Istanbul, but delegated competence and the office holding the file should be confirmed in writing on the application date.

Which documents should owners check?

Review the title and land-share table, meeting notice and minutes, the offer or contract voted on, notarial notice or posting records and any valuation. Procedure, authority to represent, inheritance or title disputes and pending litigation can affect the outcome. File-specific legal advice should be obtained for time-limited steps.
