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

A 3-season room has screened or thin-glass walls with no HVAC — comfortable spring through fall but unusable in winter in Bowie MD. 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 Bowie MD?

A 4-season sunroom typically returns 50–70% of its cost at resale in Bowie MD. 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 Bowie MD?

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