Do I need a permit for attic remodeling in Houston?

How do you handle HVAC for an attic conversion?

We extend the existing HVAC system with new ductwork or add a ductless mini-split depending on your system capacity and the attic size. Houston summers make proper climate control in attic conversions non-negotiable — we size this correctly so the space is comfortable year-round.

How long does an attic remodel take?

A standard attic conversion with drywall, flooring, HVAC, and electrical typically takes 6–12 weeks from permit approval. More complex projects with bathroom additions or significant structural work run 12–18 weeks. We provide a detailed timeline before work starts.

What’s Included in Our Attic Remodel

Structural assessment & engineering — We evaluate existing rafters/trusses, load capacity, and headroom before committing to a scope. Truss modifications require engineered drawings.
City of Houston permits — We pull all required building, electrical, and mechanical permits and schedule all inspections. You don’t have to deal with the city.
HVAC extension or mini-split — Houston attics need proper cooling. We extend existing ductwork or add a ductless mini-split sized for the space. No guessing on BTU requirements.
Electrical rough-in & finish — Circuits, outlets, switches, recessed lighting, and any required panel upgrades. All work to NEC code.
Insulation & drywall — Spray foam or batt insulation to code, drywall hang and finish, ready for paint. We use moisture-resistant drywall where appropriate.

Most Houston attics can be converted if they have adequate headroom (typically 7.5 ft minimum in the main area), structurally sound rafters or trusses, and access for a proper staircase. Truss-framed roofs (common in post-1980s Houston homes) require structural engineering to open the space. We assess all of this in our free on-site consultation at no charge.
