How Location Affects Your Buildout Timeline

Los Angeles County

LA has complex permitting. Add 2-4 weeks for permit approval. High demand for contractors can also extend scheduling. We are expert general contractors in Los Angeles and can help navigate this.

San Diego County

San Diego offers more streamlined permitting, but projects requiring specialized materials may see minor delays.

Phoenix, AZ & St. George, UT

These markets often have faster permitting but unique weather considerations (summer heat, winter snow) that can affect schedules.

Key Phases of a Commercial Buildout

  1. Pre-Construction (2-8 weeks): Design, permitting, and final planning.
  2. Demolition & Site Prep (1-2 weeks): Clearing the existing space.
  3. Rough Construction (3-8 weeks): Framing and MEP (Mechanical, Electrical, Plumbing).
  4. Finish Work (2-6 weeks): Drywall, flooring, paint, and fixtures.
  5. Final Inspections & Occupancy (1-2 weeks): Final walkthrough and Certificate of Occupancy.

How to Minimize Delays

  • Hire an Experienced Local Contractor: Their knowledge of local codes and inspectors is invaluable.
  • Finalize Plans Early: Avoid change orders, the #1 cause of delays.
  • Order Long-Lead Items ASAP: Custom fixtures or specialty equipment should be ordered during the permit phase.
