# How Should a Turnkey Renovation Contract Be? Legal and Technical Clauses Protecting the Client

A turnkey renovation contract is a critical document that determines rights and obligations for both the client and the company. Incorrectly prepared contracts lead to disputes and financial losses. In this guide, we address the legal and technical clauses that must be in the contract, conditions protecting the client, and important points from a master's perspective when doing renovation in Kadıköy, Bakırköy, Beşiktaş, Şişli, and all Istanbul districts.

Importance of Renovation Contract: Why Critical?

A turnkey renovation contract is critically important for the following reasons:

1. Determining Rights and Obligations: Rights and obligations of both parties are clarified

2. Cost Transparency: Total cost and payment plan are determined

3. Warranty Conditions: Warranty scope and duration are clarified

4. Dispute Resolution: Methods to be applied in case of dispute are determined

5. Legal Protection: Provides legal protection for both parties

Master's Note

Verbal agreements are legally invalid. A written contract must definitely be made. Renovation work done without a contract may be difficult to prove in case of dispute.

Basic Information That Must Be in the Contract

A turnkey renovation contract must definitely include the following information:

1. Identity Information of Parties

  • Client: Name, surname, ID number, address, phone
  • Company: Company name, tax number, address, phone, authorized person

2. Subject and Scope of Work

  • Renovation Scope: Which works will be done (kitchen, bathroom, complete renovation, etc.)
  • Work Location: Apartment address, floor, apartment number
  • Start and End Date: Start and delivery date of work

3. Technical Specifications

Technical specifications are one of the most important parts of the contract. Should include:

Material List

  • Brand, model, characteristics of materials to be used
  • Material quantities (square meters, pieces, etc.)
  • Material quality classes

Work Details

  • Detailed list of works to be done
  • Application techniques
  • Standards (TS, EN standards)

Master's Note

In technical specifications, vague expressions like "quality material" should not be used. Specific expressions like "X brand Y model ceramic, 60x60 cm, porcelain" should be used.

Payment Plan: Payment Conditions Protecting the Client

Payment plan should be arranged in a way that protects the client.

Recommended Payment Plan

Step 1: Site Visit and Project (At Signature)
  • 10-15% of total amount
  • In return for site visit and project preparation
Step 2: Material Purchase (At Work Start)
  • 30-40% of total amount
  • For material purchase
Step 3: Work Progress (At Halfway Point)
  • 30-40% of total amount
  • According to work progress
Step 4: Delivery (When Work is Completed)
  • 15-20% of total amount
  • After work completion and acceptance

Master's Note

In payment plan, final payment (delivery payment) must definitely be between 15-20%. Low final payment increases the risk of the company leaving work unfinished.

Payment Methods

  • Cash Payment: Against receipt
  • Bank Transfer: Transfer receipt should be kept
  • Check: Dated checks are risky (not recommended)
