How Location Impacts Your Timeline

Permitting and labor availability vary significantly by location. Here’s a quick overview:

Los Angeles & Orange County

Expect longer permit times (add 2-4 weeks) due to complex regulations, especially in coastal zones. High demand for skilled labor means booking contractors well in advance is crucial. Learn more about our services as a general contractor in Los Angeles.

San Diego County

Generally balanced timelines with year-round construction weather. Coastal Commission can add time to projects near the water. See our expertise as a general contractor in San Diego.

Arizona & Utah

Faster permitting but be mindful of seasonal weather. Extreme summer heat in Phoenix or winter snow in Flagstaff can impact schedules.

How to Keep Your Project On Schedule

  • Finalize Designs Early: Avoid change orders, which are a primary cause of delays and cost overruns.
  • Hire an Experienced Local Contractor: They understand local permit processes and have established relationships with inspectors.
  • Order Long-Lead Items Early: Custom windows, doors, and specialty fixtures should be ordered during the permit phase.
  • Budget for Contingencies: A 15-20% buffer in both your timeline and budget is essential.
