Permits for Home Additions: What Homeowners Should Expect

Why permits belong at the beginning of the plan

A room addition changes more than the amount of living space in a home. Structural loads, electrical work, HVAC, plumbing, setbacks, drainage and zoning can all affect what needs to be reviewed.

What may be reviewed

The exact requirements depend on the project and locality, but an addition may involve zoning review, building plans, structural details and inspections at different stages of construction.
