Most casita frustration comes from fuzzy handoffs: nobody says who checks the lot, who prices the job, who pulls the permit, who builds. Here is our process with the names attached. Short version: we plan, price, and coordinate; licensed Arizona contractor partners build.
Who: Modern Casita Builders. Send your address and city. We screen zoning, setbacks, lot coverage, and your city’s meter & permit rules, and answer within 1 business day with a straight yes / probably / no.
Who: us, with the licensed building partner. A site review looks at access, utilities, and anything unusual on your lot. Then you get your model’s final price in writing — including separate-meter work if your city requires it — before any contract exists.
Who: the licensed building partner. It prepares engineered plans for your lot, submits them, and pulls the building permit under its own Arizona ROC license. Your contract for construction is with the partner, and it names the partner as the builder.
Who: the licensed partner builds; the city inspects. Foundation, framing, systems, finishes — then final inspection and keys. We stay your point of contact for questions the whole way.
Address, city, and how to reach you. We do the rest of the homework.
