We build casitas, guest houses, garage conversions and in-law suites. We work across the East Valley and Phoenix. Arizona law now lets homeowners in larger cities add up to two ADUs to their lot.
ARIZONA'S ADU LAW
House Bill 2720 took effect on January 1, 2025. Cities with 75,000 people or more must allow ADUs anywhere a single-family home is allowed. Near us, that means Phoenix, Scottsdale, Mesa, Gilbert, Chandler and Tempe.
Your lot and your HOA still matter. We go over both at the free consultation.
WHAT WE BUILD
A detached casita gives family or guests their own space. It can also bring in rent. We build them from the ground up, from the slab to the finishes.
What's Included
Free consultation and estimate
Your garage already has a slab, walls and a roof. Turning it into a bedroom or a suite is often a quicker way to add living space.
What's Included
Free consultation and estimate
An in-law suite keeps a parent close and still gives everyone privacy. We build it as an attached unit or convert space you already have.

HOW IT WORKS
We visit your home, look at the lot and talk through what you want to build and why.
You get a clear quote. Then we handle the design coordination, permits and zoning with your city.
Our crew builds the unit and keeps you posted as it goes. We schedule the city inspections.
We walk the finished space with you. Then it's ready for family, guests or a tenant.

REVIEWS
We hired Masizo Development to build our Casita and working with Steve was a pleasure. Steve did everything he said in a timely manner. One of the best things I liked is that Steve always stayed in contact with me and was always reachable. From the Design until the project was completed Steve made the project and all his contractors easy. All the subcontractors that Masizo used were as nice and friendly as Steve. We will be working with Masizo on the next project. Thanks to Steve and the entire Masizo Development crew.
Greg Gallagher7 months ago on GoogleWe hired Masizo development to redo the entire master bathroom! Loved Steve! There's a lot going on in the world so finding good people that care was important. The team was great and make you feel like family. We plan on using them again for other projects like our future casita home build in Phoenix. Can't say enough goodness about this company you will be in good hands! Very responsive and thoughtful.
Angela Reyes3 years ago on GoogleWe decided to build a custom ADU casita from the ground up in the back of our home in Phoenix. Our plan was to build a new ADU for us to move into and rent out the existing front house out. We wanted to make sure that we hired a team that was well versed, not only ADU construction, but also has experience in custom home development. I liked the fact that Steve was licensed and communicated very well through out the entire project. This made the process a lot easier from the planning stage through the construction. I thought their team was very knowledgeable and professional. I was very pleased with their work and the timeline it was completed. They were very transparent the entire time and i am going to use them again in the future as well as recommend to anyone! Thanks guys
