Austin TX General Contractor
Room Addition Austin TX
Jay's Construction Contractors adds rooms to Austin homes — bedrooms for growing families, dedicated home offices for remote workers, bathrooms for expanding households, and bonus rooms for entertainment. We handle permits, framing, roofing, and finish work. No money upfront.
Expand Your Austin Home Without Moving
Austin's neighborhoods are established and desirable — but the homes in Hyde Park, Crestview, South Lamar, East Austin, and other in-town areas were often built in an era of smaller floor plans. A room addition lets you stay in the neighborhood you love, keep your kids in their school, and add the space you actually need without facing today's competitive Austin real estate market.
Jay's Construction Contractors builds room additions that are fully integrated into your existing home — same roofline style, matching exterior cladding, consistent interior finishes. We do not build obvious-looking afterthoughts. Every addition we construct is engineered to look like it was part of the original plan.
Before any project begins, Jay visits your property to assess your lot, discuss zoning constraints, and understand your goals. Austin's zoning code includes rules about setbacks, impervious cover, and floor-to-area ratios that determine what you can build. We know the rules and design within them — no surprises at permit time.

Our Room Addition Process
We start every room addition project with a free site visit and consultation. Jay reviews your lot survey, assesses structural considerations, and talks through your goals. We then develop a detailed scope of work and provide a written estimate — no vague ranges, no hidden fees.
After you approve the scope, we submit permit drawings to the City of Austin. Once permitted, we begin site work: footing excavation, concrete pour, and slab or crawl space construction as required. Framing, roofing, and exterior sheathing come next, followed by insulation, mechanical rough-in, drywall, trim, flooring, and paint.
Throughout construction we coordinate all required city inspections. On completion, we walk the new space with you, address any punch-list items, and deliver the final inspection paperwork confirming the addition is fully permitted and code-compliant.

Can you add a room without major disruption to my home?

A standard room addition takes 8 to 14 weeks from permit issuance. City of Austin permitting itself can take 4 to 8 weeks depending on project complexity.
