Pro Tips from Michigan Contractors
1. Document Your Work
Even without permit requirements, maintain detailed documentation including cable test results, as-built drawings, and photos. This protects you during warranty claims and helps customers with future moves or additions.
2. Understand the Line Between Low Voltage and Electrical
Any work involving 120V or higher requires an electrical permit and licensed electrician in Michigan. This includes installing outlets for network equipment, UPS power circuits, and server room electrical.
3. Get Written Scope Agreements
Since no permit process defines the scope, clear written agreements with customers are essential. Define exactly what is included and excluded from your work.
4. Consider BICSI Certification
While Michigan does not require it, BICSI Registered Communications Distribution Designer (RCDD) or Installer certifications demonstrate professionalism and can differentiate your business.
