AutoCAD Drafting & Design in Arizona
Commercial tenant improvement plans and residential construction documents for Phoenix, the West Valley, and greater Maricopa County — produced by a locally based drafting studio.
REH Drafting & Design is headquartered in the Phoenix West Valley, and Arizona is home turf. That matters because a drawing set isn't generic: it's built for a specific jurisdiction's submittal checklist, plan-review habits, and code adoptions. We produce permit-ready AutoCAD construction documents for commercial and residential projects across Maricopa County.
Commercial Tenant Improvement in Arizona
Phoenix and the West Valley are absorbing commercial tenants fast — and every office suite, restaurant space, and converted warehouse needs a permit set the city will approve. Our commercial tenant improvement drafting covers office, retail, and restaurant buildouts, change-of-occupancy conversions, and interior remodels, with code analysis and ADA coordination built into the set from day one.
- Title sheet with code analysis and occupant load for your jurisdiction
- Demolition, floor, ceiling, power, and finish plans
- Plan-check support through the city's review cycles until approval

What's in an Arizona TI permit set
Every project is scoped to what your jurisdiction actually requires, but a representative Maricopa County tenant improvement set includes:
- Title sheet with code analysis: occupancy classification, occupant load, and egress summary against the adopted International Building Code and local Arizona amendments, so the reviewer's first questions are answered on sheet one
- Existing conditions and demolition plans: clearly separating what stays from what goes
- Proposed floor plans: dimensioned partitions, door and hardware schedules, and wall types
- Reflected ceiling, power, data, and finish plans coordinated with how the tenant will actually run the space
- Accessibility details to the ICC A117.1 standard the building code references
- Coordination sheets for the mechanical, electrical, plumbing, and structural work your licensed consultants stamp
Change of occupancy in Arizona
A change of occupancy happens when a space's new use falls in a different occupancy group under the building code — for example converting a warehouse (Group S) into offices (Group B). The building department then evaluates the space against current code for the new use, which can pull in accessibility upgrades, added restrooms, mechanical ventilation, egress changes, and fire separation. It is the single biggest driver of unexpected cost and schedule on a Maricopa County TI, so we map those triggers before you commit. The mechanics are walked through in our warehouse-to-office conversion guide.

Residential Drafting in Arizona
From custom homes on West Valley acreage to casitas and ADUs in established Phoenix neighborhoods, our residential drafting service delivers the site plans, floor plans, elevations, and details Maricopa County jurisdictions require. Arizona's ADU and guest-house rules have their own quirks — we cover them in our guide to the difference between a Casita and a Guest House.

Why Local Matters at Plan Review
Every Arizona jurisdiction runs its own submittal requirements, review queues, and comment styles. A set that anticipates them moves; a set that doesn't gets bounced, and every bounce costs weeks. Because REH combines drafting with project management, jurisdiction requirements, code analysis, and consultant coordination are handled as one workflow — from first submittal through approval.
