Low voltage is the only trade that gets cheaper the earlier it is involved and more expensive every week after. Pre-wire during rough-in costs a fraction of a retrofit through finished drywall, and the homeowner never sees the difference.
The window
A new residential permit gives you roughly six to ten weeks before walls close. That is the entire selling window for structured wiring, network drops, and camera rough-ins on that address.
Commercial is the better margin
- Office and medical up-fits need access control, door hardware integration, and network cabling on a fixed schedule.
- Warehouse and light industrial filings drive camera counts and long cable runs.
- Any filing that lists an electrical subcontractor is a partner lead as much as a project lead.
