"Straight Edge Builders did a great job navigating the complexities of converting our two-story garage to a new home for my parents. They stuck with us as we worked to overcome mistakes by the architects (don?t hire Powell & Associates) and permitting issues. They always had someone working so we never felt abandoned for another job. This was important because we needed it done as soon as possible. This project was unique for a variety of reasons. The property is a historic landmark which required them to work well with our consultant and other specialty contractors. They balanced preservation requirements with modern design and handicapped accessibility throughout. Overall, Mitch and Dustin exceeded expectations at every turn. They expertly customized the project to our unique needs. We would highly recommend them for any project that requires skill, adaptability, and a high level of care."

FAQs for drafting or cadd service projects in Ontario, CA

You’ll want the right pro for the job. Hire a draftsperson when you need cost-efficient technical drawings, choose an architect for a full design and aesthetics, and bring in a structural engineer if safety or load-bearing elements are in play. Each expert keeps your plans code-compliant and your project on track.

Yes, a qualified draftsperson can produce a complete set of residential blueprints for building a house without an architect’s oversight. Look for a drafting pro in your area with current certification and solid experience, then confirm with your local building department that the draftsperson’s stamp meets building codes in the area where you live.

Technically, you can draw your own blueprints, but drafting an accurate, code-ready plan is a tall order. Misplaced walls or overlooked regulations can trigger expensive delays once construction starts. If you want to stay on schedule and meet local requirements, let an architect, draftsperson, or engineer refine—or redraw—your plans. Their fee is minor compared with the cost of fixing mistakes in the field.
