Our ADU Construction Process in Coachella
Every adu construction in Coachella follows the same proven process we have refined over 17 years of Coachella Valley construction. Here is exactly what to expect when you hire Niem Construction.
Feasibility Study & ADU Design
We evaluate your property, confirm ADU eligibility under California law and local zoning, and design a unit that maximizes livable space within your lot's allowable footprint.
Permit Application & Plan Review
We submit complete construction plans to the building department, navigate ADU-specific regulations, and secure all required permits. California law mandates 60-day permit processing for ADUs.
Site Work & Foundation
Grading, utility trenching, and foundation work begin. For detached ADUs, we install new sewer, water, electrical, and gas connections from the main property.
Framing Through Finish
Framing, roofing, exterior, rough plumbing, electrical, HVAC, insulation, drywall, flooring, cabinetry, and all interior finishes are completed by our team.
Final Inspections & Certificate of Occupancy
We coordinate all required inspections, address any city corrections, and obtain your Certificate of Occupancy so the ADU is legally permitted and ready for use or rental.
