Do I Need a Permit to Finish My Basement in Texas?
Basement finishing permit requirements. Egress windows, inspections, and what you need before starting your basement remodel.
Yes — any framing, electrical, plumbing, or mechanical work requires a permit.
What Requires a Permit
Framing walls, adding electrical circuits, installing plumbing, and modifying HVAC in a basement all require a building permit. Cosmetic work — painting, laying floating floors over existing concrete, and adding furniture — does not.
Egress Windows Are Non-Negotiable
Every basement bedroom must have an egress window: minimum 5.7 sq ft net clear opening, sill no higher than 44 inches above the floor (the IRC standard most jurisdictions follow). Window wells deeper than 44 inches need a permanently attached ladder or steps. This is a life-safety requirement — inspectors will not pass a basement without proper egress.
The Four Inspections
Expect four inspections: framing (walls, fire blocking, egress openings), MEP rough-in (electrical, plumbing, HVAC before walls are closed), insulation (exterior walls, vapor barrier), and final (drywall, fixtures, smoke/CO detectors). Do not close walls before passing framing and rough-in inspections.
Common Mistakes
Enclosing the furnace room without combustion air supply, skipping egress windows in bedrooms, not adding enough electrical circuits (you'll want dedicated circuits for the bathroom and any kitchen/wet bar), and forgetting smoke detectors in every bedroom and outside sleeping areas.
Yes, you need a permit. The biggest requirement is egress windows for bedrooms. Budget 4 inspections and don't close walls before passing rough-in.
