Frequently Asked Questions
How much does a sunroom cost?
Three-season sunrooms cost $8,000–$25,000. Four-season (insulated, HVAC-connected) sunrooms cost $20,000–$60,000+. Screen enclosures are the most affordable at $5,000–$15,000. Cost depends on size, foundation type, glass quality, and whether HVAC is extended into the space.
Do sunrooms add value to your home?
Sunrooms return 40–70% of their cost at resale, depending on quality. Four-season sunrooms with HVAC add more value than three-season or screen-only enclosures. In warmer climates (Southeast, Southwest), sunrooms are especially desirable and may return higher percentages.
Do I need a permit for a sunroom?
Almost always yes. Sunrooms are considered additions and require building permits in virtually every jurisdiction. Four-season sunrooms may also require plumbing and electrical permits if HVAC, lighting, or outlets are included. Your contractor should handle the permitting process.
What is the difference between a three-season and four-season sunroom?
A three-season sunroom uses single-pane glass and no insulation — comfortable spring through fall but too cold in winter. A four-season sunroom has insulated walls, double/triple-pane glass, and HVAC — usable year-round as additional living space. Four-season costs roughly 2x more.
