Expert permit drawings for Commercial and home additions, decks, bathrooms, and basements
How it works
From your first call to permit approval — we handle everything.
Step 1:
Free consultation:
Call or message us to describe your project. We'll ask about the type of addition, your city or county, and your timeline. No commitment required — just a conversation. Hablamos Español
Step 2
Project review & quote:
We review your property details and city or county requirements. You receive a clear quote with scope of work and estimated turnaround time — no hidden fees.
Step 3:
We prepare your drawings:
Our team creates all required construction drawings — floor plans, site plans, structural details — tailored to your local building department's exact requirements.
Step 4:
Submit to the city or county:
We prepare the complete permit package ready for submission. We know what each jurisdiction requires, so your application goes in complete and correct the first time.
Step 5:
Permit approved — start building:
Your permit is approved and you're ready to break ground. If the city requests any corrections, we handle revisions and resubmittal at no extra charge
