Commercial Tenant Improvement Drafting
Commercial TI drawings that clear plan review.
Complete, code-referenced AutoCAD construction documents for office, retail, restaurant, and change-of-occupancy tenant improvements across Arizona and Southern California.
Commercial tenant improvement, by state
Based in the Phoenix West Valley, we draft permit-ready tenant improvements across Arizona and Southern California. Choose your state for local jurisdictions, what's in a permit set, and completed work.
A TI lives or dies at plan review.
The finishes and furniture don't matter until the building department approves a set that clearly shows what exists, what's proposed, and how it complies. Most schedule blowouts are documentation problems — and they're cheapest to fix before you submit.
What derails a TI
- Occupant load miscalculated
- Accessibility caught at plan review
- Missing fire separation between uses
- A set that never clearly showed existing vs. proposed
- Every bounce costs weeks
How REH prevents it
- Code analysis on sheet one — the reviewer's first questions, answered
- Existing vs. proposed clearly separated
- ADA and egress designed in, not bolted on
- Consultant coordination handled as one workflow
- Plan-check support from submittal to approval
Built for the people who move the project.
Business Owners
Signed a lease and need to open. We flag code issues before they cost you rent, and keep the permit moving.
Landlords & Property Managers
Test fits and TI sets that turn vacant space into leasable, code-compliant suites.
General Contractors
Clean, coordinated documents your crews and the inspector can actually build from.
What drives the cost and timeline of a TI set.
No two projects price the same. Rather than a flat number, here's what actually moves it — so there are no surprises in your proposal.
Scope of work
Reconfiguring a suite is a fraction of a full shell-to-finish buildout.
Change of occupancy
A new use group triggers accessibility, egress, and fire-separation review — the single biggest cost driver.
Jurisdiction
Each city's submittal requirements and review load shape the sheet list and schedule.
Consultant coordination
Structural, MEP, and health-department scope adds coordinated sheets to the set.
Every project is confirmed with a written, fixed-fee proposal after a short consult — no open-ended hourly surprises.
