# 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
- 30-40% of total amount
- For material purchase
- 30-40% of total amount
- According to work progress
- 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)
Warranty Conditions: Warranty Conditions Protecting the Client
Warranty conditions should be clearly stated in the contract.

| Structural Work | 10 years |
Warranty Scope
Warranty scope should be clearly stated:
Within Warranty Scope:- Workmanship errors
- Material errors
- Applications not in compliance with standards
- Normal wear and tear
- User error
- Natural disasters
Master's Note
In warranty conditions, general expressions like "all works are within warranty scope" should not be used. Specific warranty periods should be stated for each work category.
Contract Termination and Cancellation Conditions
Contract termination and cancellation conditions should be stated for both parties.
Termination by Client
Client can terminate the contract in the following situations:
1. Company Not Fulfilling Obligations: Works not being completed on time, non-compliance with quality standards
2. Additional Cost Request: Additional cost requests not stated in contract

3. Additional Work Request: Additional work requests not stated in contract
Additional Cost and Change Requests
Additional cost and change requests should be clearly regulated in the contract.
Additional Work Requests
Client can request additional work after contract is signed. In this case:
1. Written Approval: Additional work request should be made in writing
2. Cost Determination: Additional work cost should be notified to client
3. Getting Approval: Work should start after client approval is obtained
Change Requests
Client may want to change materials stated in contract. In this case:
1. Difference Calculation: Material difference should be calculated

Master's Note
Additional cost and change requests should not be made verbally. Must definitely be made in writing (email, WhatsApp message, etc.) and approval should be obtained.

1. Discussion and Negotiation
First step is discussion and negotiation between parties.
2. Mediation
