Our building expertise includes not only remodeling of existing homes, but new custom home construction, multifamily housing, tenant improvements, commercial and industrial office buildings. Our professional staff has the experience necessary to give you the confidence to start your next project today.

"McGee construction recently insulated, dry walled, and added electrical outlets my garage. They were quick and efficient in completing the project. It was a pleasure working with Cade who coordinated everything and was very hands on making sure everything was to our liking. Cade was very hands on making sure things were kept at a certain standard. We got quotes from 5 other companies and McGee Construction was the company we ultimately decided to go with because they are very fairly priced and overall just had good vibes when talking with them. We definitely do not regret our choice and would recommend them for anyone looking to start a new project for their home."

"Full kitchen and bathroom remodel. (Loft condo) From my initial meetings with Anar the owner, to meeting the team that did the install It was an entirely stellar experience. Anar presented me with samples and a clear understanding of the project scope. A project manager was assigned that came out to the site on a regular basis to monitor progress and quality. The two gentleman that came out to do the installation were personable..and maintained a clean workspace and professional attitude throughout. Both obviously skilled for the job duties. There was great care taken during the project on communication regarding the installations, and leaving the site as undisturbed as possible (clean) and with respect to property rules. (Condo). The fixtures and materials offered were all top quality and brands. Project oversight and city permits were all handled by the project manager. A very high level of communication and attention to detail were provided throughout the project. My spouse and I are very happy with the results, and this is added tremendously to the value of the property. This is our first remodel, and although it is an inherently stressful undertaking, Anar and his team really delivered with service and quality. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ gentleman! Thank you again!

Home Building questions, answered by experts

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

Many providers assist with obtaining necessary permits. Confirm with your contractor.

Complex plumbing is tricky and expensive in an off-the-ground dwelling like this. By considering options like composting toilets, rainwater collection, and gray-water sinks, you save money and help the environment. 

Yes, a garage apartment is generally considered a valuable asset as long as the new structure has been legally built. It's important to weigh the cost to build a garage with an apartment against the cost to convert a garage to living space if you already have a garage.

Any straightforward rectangular home layout is more uncomplicated than custom rooms, additions, or stylistic features. In stock plans, single-story ranch homes, cape cods, and colonials are common. Layouts with a single roof ridge are easier to build than those with multiple dormers, chimneys, or ridges.
