Home Additions in Phoenix, AZ

Phoenix's wide mix of pre-1990 ranch homes in Arcadia, Encanto, North Central, and Coronado is ideal for additions. Generous lots, single-story footprints, and underbuilt 1,200–1,800 sq ft floor plans leave plenty of room for primary-suite additions, great-room expansions, and second-story pop-tops that more than double living area.

Newer Phoenix (Desert Ridge, Ahwatukee) usually requires more careful HOA review and tighter setbacks, but offers excellent candidates for detached casitas and back-of-lot ADUs under the City of Phoenix accessory dwelling ordinance.

We sequence design, structural engineering, permitting, foundation, framing, MEP, drywall, and finish under a single contract — one schedule and one weekly walk-through.

ProWorx Restoration designs and builds home additions across the Phoenix metro that look and perform like original construction. Typical scope: extra bedrooms, primary-suite expansions, family rooms, home offices, sunrooms, casitas, ADUs, and second-story additions. We self-perform framing through finish and manage licensed MEP trades under a single contract, with Arizona ROC #349454.

Adding square footage in Arizona means working around realities that don't apply elsewhere: slab-on-grade foundations that require core-drilling and slab patching for any new plumbing branch, post-tension slabs that need engineered tendon scans before any saw work, 110°F roof-tile work windows that compress the dry-in schedule, and HVAC systems that frequently can't handle the added load without zoning or supplementing. We surface and budget all of this during pre-construction, not during framing.
