Final answer:
The first thing a contractor should do before beginning work on a home extension is to obtain permits and approvals, conduct an inspection of the existing structure, and collaborate with the homeowner to develop a detailed plan.
Step-by-step explanation:
When adding an extension to a home, the first thing a contractor should do before beginning work is to obtain the necessary permits and approvals from the local government. This is important to ensure that the extension complies with building codes and regulations.
The contractor should also conduct a thorough inspection of the existing structure to identify any potential issues or limitations that may affect the extension. This may include assessing the foundation, structural integrity, and feasibility of the site.
Additionally, the contractor should collaborate with the homeowner to develop a detailed plan and obtain any required architectural or engineering drawings. This will help in determining the scope of work, materials needed, and estimated costs for the project.
