1-3 days of work, 1-4 weeks including permitting. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are linear footage and number of gates; material: chain link, wood, vinyl, aluminum or composite; fence height (4 ft front yard versus 6 ft rear yard).
