Hello, my parents are remodeling their home and I was wondering what kind of fee is the industry standard for the general contractor of the project to charge? I believe it's typically set up as Cost Of Materials + Percentage Fee Of Contractor = Total Project Cost. My question is what is the typical percentage fee of the general contractor for a major home remodel project (e.g. 10%, 15%, etc)? The project is anticipated to go around 6 months and is adding about 1200 square feet to the home (included a new a/c, ductwork, fireplaces, roof, etc) if that info makes any difference. Thanks!
