Frequently Asked Questions
Does a sunroom add value to a home?
Yes, but the ROI varies. A well-built four-season sunroom returns about 50-75% of its cost. Three-season rooms return slightly less. The value depends heavily on climate — sunrooms are more valued in northern and temperate climates where they extend outdoor enjoyment.
Do I need a permit for a sunroom?
Almost always yes — a sunroom is a structural addition to your home that must meet building codes. Permits typically cost $500-$2,000 and require structural, electrical, and sometimes HVAC inspections.
