What does a Dwelling Certificate permit a contractor to do?

• A. Only sales
• B. It permits planning, sales, installation, maintenance, or servicing of a one- or two-family dwelling fire protection sprinkler system or any part of such a system
• C. Only residential wiring
• D. Only maintenance for commercial systems

Answer: (B)

A Dwelling Certificate sets the scope of work for a contractor on fire protection sprinkler systems in one- or two-family homes. It covers the full range of activities needed to bring and keep a dwelling sprinkler system in service: planning the system, selling it, installing components, and performing maintenance or servicing of the system or any part of it. This breadth is what makes it the best choice, because it includes design, procurement, installation, and ongoing care.

The other options are too narrow or outside the dwelling scope: restricting to sales omits installation and servicing; focusing only on residential wiring isn’t about sprinkler work; and limiting maintenance to commercial systems doesn’t apply to dwelling systems at all.
