Permit-Ready Design Documentation

PermitPro Design specializes in preparing clear, buildable, and permit-ready design documentation for residential projects. We focus on ADUs, garage conversions, structural modifications, home additions, and new residential construction. Our work includes architectural drawings, structural design, foundation plans, wall and roof framing plans, MEP layouts, structural calculations, and plan check revision support — all the documentation you need to move a project from concept to permit approval. We work with homeowners, contractors, builders, architects, permit expediters, real estate investors, and developers across a wide range of project types and locations.

What We Do

Our Core Values

Permit-Focused Documentation

Every drawing and calculation we prepare is organized and detailed with permit review in mind — clear enough for reviewers, accurate enough for contractors.

Cross-Discipline Coordination

Architectural, structural, and MEP documents are coordinated together so the drawing set is complete and consistent before submission.

Works With Your Team

We collaborate with homeowners, contractors, architects, and permit expediters to produce documentation that works for everyone involved.

Full Revision Support

We stay with projects through plan check responses, revision rounds, and resubmission — not just the initial drawing delivery.

ADU & Garage Expertise

We specialize in the residential project types that homeowners and contractors actually build — ADUs, garages, additions, and structural modifications.

Clear, Buildable Drawings

Our drawings are properly dimensioned, clearly noted, and detailed enough for field use — not just for permit review.
