Permits, Plans & the City
Additions live or die in permitting. As your licensed general contractor (AZ ROC #366121) we coordinate drawings, engineering, and city permits — Glendale, Peoria, Phoenix, and the rest of the West Valley — and we build to pass inspection the first time.
Frequently Asked Questions
How much does a room addition cost in the Phoenix area?
Most additions run $250–$400+ per square foot depending on scope — a bathroom in the addition, kitchen tie-ins, and structural complexity move the number. We quote firm after a free site visit and a look at your lot.
How long does an addition take?
A typical room addition runs 8–14 weeks from permit approval; casitas and ADUs longer. Permitting itself varies by city — we handle it and keep you posted.
Is a casita/ADU worth it?
In the West Valley, usually yes — rental income and multigenerational living keep demand high, and Arizona law has made ADUs easier to permit. We can walk your lot and tell you honestly what fits.
Do you handle the design?
We work with drafting and engineering partners for plans and calcs, and manage that process inside your project — one contract, one point of contact.
