    Home Additions Built for Scottsdale Homes

    Scottsdale additions almost always run through a community Design Review Board before the City of Scottsdale will issue permits. DC Ranch, Silverleaf, Desert Mountain, Troon, and Grayhawk each have distinct material palettes, massing rules, and submittal cycles — we've completed full DRB packages for all of them.
    Common scopes: primary-suite expansions with spa baths, detached guest casitas over 600–1,200 sq ft, garage-to-living conversions plus new detached garages, and great-room expansions with view-corridor preservation.
    Older Scottsdale (Old Town, Hy-View, Village Grove) trends toward second-story additions and pop-up casitas on tear-down-candidate ranch lots — we work both ends of the market.

    Why Scottsdale Home Additions Is Different

    DRB review adds 6–12 weeks before any permit is filed. We submit massing studies, material boards, and exterior elevations on the front end so design changes aren't fought during framing.
    North Scottsdale hillside lots (Troon, Pinnacle Peak, Desert Mountain) frequently trigger Hillside Development Standards review — additional engineering, drainage, and ESLO compliance. We coordinate the civil engineer and surveyor up front.

    How We Approach Home Additions

    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.
