Modern Casita Builders exists because of a simple frustration: in Arizona’s casita industry, almost nobody will tell you a price. We will — and we’ll show you the city rules that move it.
Modern Casita Builders was founded by Christian Marquez — a licensed Arizona real estate agent (The Marquez Group at At Home Real Estate, AZ license SA657877000), a rental-property owner who manages his own units, and someone who helped start three of the Valley’s casita companies before this one. He has sat in the sales meetings, walked the lots, and watched how casita pricing gets built from the inside.
What he saw: good builders doing honest work, wrapped in a sales process that hides the only number homeowners actually ask for. Prices behind “free consultation” walls. Meter rules nobody mentions until they show up as a change order. Marketing claims nobody can verify.
Modern Casita Builders is the planning, feasibility, and marketing side: we screen your lot, explain your city, price the project honestly, and coordinate the process. The construction itself is performed by licensed Arizona contractor partners — they hold the ROC licenses, pull the permits, sign the build contracts, and warranty their work. That structure is deliberate and it’s spelled out on the Licensing & How We Work page.
Christian also brings the two perspectives most casita salespeople don’t have: he’s a landlord, so the rent math on this site is written by someone who collects it; and he’s a licensed Realtor, so when a casita doesn’t pencil on your lot, he can tell you what your property’s other options are worth instead of forcing a build that doesn’t fit.
