Home Addition Construction

Every addition starts with a feasibility review — lot coverage, setbacks, HOA architectural rules, and existing structural capacity. We then produce stamped drawings, run structural engineering for any second-story or load-bearing modification, and submit to the city alongside the HOA ARC package. Construction sequences footings, framing, dry-in, MEP rough, inspections, drywall, finishes, and exterior tie-in. For most single-story additions in Phoenix, Chandler, or Gilbert, plan on 12–18 weeks on site after permits. Second-story work runs 18–26 weeks. We provide weekly schedule updates and a single project manager from contract through final inspection. See related residential construction work.

Three constraints dominate Phoenix-metro additions. First, slab-on-grade construction: any new bathroom or kitchen in an addition needs slab cuts or core-drilling for drains, and post-tension slabs require tendon scans before any saw work. Second, HVAC capacity — existing 3- or 4-ton systems often cannot heat and cool added square footage, so we either zone, supplement, or upsize the system. Third, electrical panel capacity. 1990s–2000s tract homes often run 150–200A panels already near capacity; a primary-suite addition with an electric tankless heater, mini-split, or EV-adjacent loads frequently triggers a panel upgrade. We surface all three during the pre-construction walk so they're budgeted, not surprises.

We frame to IRC and Arizona-amended IBC with hurricane-rated framing where wind exposure warrants. Stucco matches the existing three-coat assembly with color samples pulled before mobilization. Roof tile is sourced from the original supplier when possible; when discontinued we pull tile from inconspicuous areas (rear-facing slopes) for visible elevations. Windows are dual-pane low-E with U-factor and SHGC meeting the Arizona Energy Code. All work is permitted and inspected, backed by a written workmanship warranty, and performed under ROC #349454. For damage-driven additions, we coordinate scope and pricing with your carrier through our insurance restoration process.
