Q: Can I choose my own contractors?

Yes. The homeowner selects, hires, directs, and pays properly licensed, bonded, and insured contractors. CMGWA may administratively send owner-approved bid requests and organize responses.

Q: Do you help with permits?

Yes. At the homeowner’s request, CMGWA can prepare permit paperwork using homeowner-provided information and organize related documents and status records. The homeowner reviews, signs, and submits the paperwork and remains responsible for applications, approvals, compliance, and required professionals.

You don’t need a general contractor to manage your build. But without the right organization, a few wrong decisions, missed deadlines, or incorrect material orders can quickly erase the money you planned to save.

Why owner-builders need CMGWA

Saving the markup is only the beginning.

20+ years

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.

One wrong order can cost thousands.

Incorrect quantities, missed lead times, and materials arriving out of sequence can stall multiple trades at once.

One delayed decision can cost months.

Selections, bids, documents, and owner decisions must be ready before the next phase—not after the crew is waiting.

Organization protects your savings.

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

You do not need traditional builder markup. You do need a system.

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 Build

Do the math

That 15–30% markup can easily become more than $100K.

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.

Common questions

What Washington owner-builders want to know.

Is CMGWA my general contractor?

No, because you act as your own general contractor. That’s how we save our clients, on average, $100K. You still get all the organization, administrative management, supplier discounts, and warranties.

Can I choose my own contractors?

Yes. You select, hire, direct, and pay properly licensed, bonded, and insured contractors. At your request, CMGWA may administratively send owner-approved bid requests and organize responses for your review.

Do you help with financing?

CMGWA may provide lender contact information and organize owner-provided information into a budget document. The homeowner and lender make all financing decisions.

Do you create my build budget for the bank?

Yes, we do. We prepare your build budget sheet so you can hand it to the bank. Most banks won’t work with owner-builders, but we have relationships with a few lenders who work with our owner-builder program because they know our process and experience.

Do you create our schedule?

Yes. We create your build schedule and help keep your build on track. Ask us how.

Do you get our bids?

Yes, we do. We request and organize bids for your review, and our software helps you compare them so you know you’re getting what you need and comparing apples to apples.

Do you help with permits?

Yes. If you want us to, CMGWA can fill out permit paperwork using the information you provide and organize related documents and status records. You review, sign, and submit the paperwork and remain responsible for applications, approvals, compliance, and required professionals.

How much can I save as an owner-builder?

Our clients save, on average, $100K. Actual savings depend on the location, size of the home, finishes, bids, market conditions, and other project-specific factors.
