Tell Us About Your BuildWhy owner-builders need CMGWA
Our process and program are built on the knowledge base of a general contractor and project manager with more than 20 years of management experience.
CMGWA provides administrative and project-organization services and does not act as the homeowner’s general contractor.Incorrect quantities, missed lead times, and materials arriving out of sequence can stall multiple trades at once.
Selections, bids, documents, and owner decisions must be ready before the next phase—not after the crew is waiting.
You remain the owner-builder and make every construction decision. CMGWA organizes the budget information, bid documents, schedules, selections, and project records that help you keep the build moving.
A smarter owner-builder path
A traditional general contractor may charge substantial overhead and markup to manage your custom home. As an owner-builder, you can keep control of those dollars and choose the licensed, bonded, and insured contractors you want to hire.
CMGWA provides the administrative structure that a complex build demands. We organize owner-provided information and records while you direct the project, select contractors, approve purchases, and make every construction decision.
Talk Through Your BuildDo the math
Traditional general contractors commonly add 15–30% to subcontractor, supplier, and material bids. On a custom-home build, that percentage compounds across the entire project—and the total can climb quickly.
That is why our clients save, on average, $100K. When owner-builder rules and lender requirements allow, you do not need to pay traditional general-contractor markup. You do need a proven system built from the knowledge base of a general contractor and project manager with more than 20 years of management experience.
