Architectural CAD Drafting

Residential & Commercial
From single-family additions and ADUs to commercial tenant improvements and mixed-use projects. Complete CAD solutions across every project type at the same standard.
CAD Solutions Beyond Drafting
BIM coordination, as-built documentation, redline-to-CAD conversion, contractor bid packages, and construction design support, all under one roof.

Why CADTRI
We understand construction from every angle.
Whether you are a contractor, architect, developer, or property owner, we know what works and what gets rejected.
Permit-Ready Every Time
Our professional CAD services are built specifically to get permits approved on the first submission. We research your jurisdiction, understand what the plan checker wants, and deliver drawings that work.
BIM Coordination That Prevents Problems
We coordinate architectural, structural, MEP, and all other systems so conflicts are caught before they reach the plan checker. That saves you money. That saves you time.
Strategy Before CAD
Before we open AutoCAD, we do project planning to confirm the project can actually happen. We answer the real questions: can this be built, will the city approve it, and what is the timeline.
Complete Compliance Documentation
Title 24 energy compliance, accessibility requirements, and all the building compliance documentation that makes permits stick. Handled as part of every complete drawing package.
How It Works
From intake to permit approval.
A structured four-step process designed to eliminate surprises and keep your project on schedule.
We Research Your Jurisdiction
Before we touch CAD software, we figure out what your city actually wants. That is how permit set preparation gets done right, built to local standards from day one.
We Build It Right the First Time
Our architectural CAD drafting follows every local requirement. Coordinated, complete, and ready to submit, not a draft requiring additional work on your end.
You Submit. We Stay Available.
If the city has questions, we respond. If they want revisions, we handle them. That is what real construction documentation services look like.
You Get Your Permit
That is the goal. Permits that actually happen, on schedule. The engagement is not closed until the permit is issued.
