What does a general contractor do?

<div>General contractors are the ones that coordinate home construction projects. They are in charge of the day-to-day oversight of the subcontractors to ensure that the project is completed on time and to resolve problems as they arise. General contractors:<ul><li>Complete pre-construction planning, both with the customer and crew</li><li>Provide realistic cost estimates</li><li>Develop construction timelines</li><li>Ensure deadlines are met</li><li>Acquire permits as needed</li><li>Purchase supplies and materials</li></ul></div>

What questions should I ask a general contractor?

<div>Before hiring a general contractor for your home project, it’s a great idea to write down a list of questions to discuss with each prospect. Some example questions to get you started include:<ul><li>Which types of insurance do you carry?</li><li>Can you provide a list of references?</li><li>What is the expected timeline for this project?</li><li>How will my project be supervised?</li><li>Will you hire subcontractors for the job?</li><li>What is the best way to communicate changes?</li><li>Will you obtain all of the required building permits?</li></ul></div>

Should general contractors be certified or licensed?

<div>While city and state laws vary on general contractor licensing requirements, hiring an unlicensed general contractor could lead to poor quality work, costly future expenses, and potential code violations. Be sure to check our <a href="https://www.angi.com/angi-license-check.htm">state licensing tool</a> to review the local general contractor guidelines for your area.As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: <ul><li>The owner, principal, or relevant manager passed a criminal background check</li><li>Required to have applicable state and local licenses</li><li>Maintain an average star rating of 3.0 or better on our network, if they have at least one review</li><li>Paying to advertise their services</li><li>Meeting any other eligibility criteria required by Angi</li></ul>Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.</div>
