Frequently Asked Questions

How much does a sunroom addition cost in Provo?

Sunroom additions in Provo cost $14,800–$117,600. A basic 3-season room (200 sqft) runs $14,800–$9,600. A 4-season heated/cooled sunroom costs $9,600–$44,000. A full solarium with glass roof can reach $117,600. Prefab kits start around $8,000–$15,000 but require a prepared foundation.

3-season vs. 4-season sunroom — what's the difference in Provo?

A 3-season room has screened or thin-glass walls with no HVAC — comfortable spring through fall but unusable in winter in Provo. A 4-season room has insulated walls, double-pane windows, and a mini-split system — livable year-round and often counts as conditioned square footage, adding more home value.

Does a sunroom add home value in Provo?

A 4-season sunroom typically returns 50–70% of its cost at resale in Provo. A well-built sunroom adds livable square footage, improves natural light, and has strong buyer appeal. 3-season rooms return less (30–50%) since they're seasonal.

Do I need a permit for a sunroom in Provo?

Yes — sunrooms are permanent structure additions and require a building permit in virtually all jurisdictions in Provo. You'll need architectural drawings for a 4-season room. Processing typically takes 2–6 weeks. Your contractor should handle the permit application.
