Contractors set their service radius once and rarely revisit it. Permit volume moves every quarter, and the difference between a 30-minute drive and a 55-minute drive is often the difference between bidding against ten firms and bidding against two.

How to redraw the map
- Rank your ZIPs by permits per month, then divide by the number of crews you can realistically send there.
- Drop the ZIPs where drive time exceeds your billable-hour tolerance, even if volume looks good.
- Watch for ZIPs that doubled quarter over quarter — those are subdivisions coming online, and early entrants get the repeat builder relationship.
Why the swings matter more than the average
March came in at 910 units and April at 1,224. Averaging those hides a 34 percent swing in workload that hit crews about six weeks later. Tracking permits weekly is how you staff for the swing instead of reacting to it.
