Commercial General Contracting
Arizona's Licensed Commercial Construction Leader
Commercial construction in Arizona demands more than a license — it requires a contractor with the experience, systems, and professional discipline to manage complex projects from pre-construction through final delivery. Partain Builders LLC brings all of that and more.
As a KB-1 Dual Building Contractor (ROC 343653), we are licensed to perform the full range of commercial building construction in Arizona — from ground-up office buildings and retail centers to industrial facilities, medical offices, and tenant improvements. Our dual licensing also includes an A General Engineering license (ROC 352354), which extends our capability to projects that involve engineering-related construction work.
We manage every phase of your commercial construction project — pre-construction planning, permitting, subcontractor management, quality control, and closeout — with a single point of accountability and clear communication throughout.

How We Work
Our Construction Process
01
Pre-Construction Planning
We begin every project with thorough pre-construction planning — reviewing plans, identifying risks, establishing schedules, and building a detailed budget before a single shovel hits the ground.
02
Permitting & Compliance
Our team manages the permitting process from start to finish, coordinating with local jurisdictions, plan reviewers, and inspectors to keep your project moving without delays.
03
Construction Management
We manage all trades, subcontractors, and suppliers with a focus on quality, safety, and schedule adherence. Daily site supervision ensures nothing falls through the cracks.
04
Quality Control & Closeout
Rigorous quality control throughout construction and a thorough closeout process — punch lists, final inspections, documentation, and owner training — ensure a smooth project completion.
