Ground-up builds, on your lot
Custom Home Builder in Phoenix, AZ
A custom home is the largest construction project most people will ever commission, and the way it usually goes wrong isn't bad framing or bad concrete — it's the gaps between companies. The designer who doesn't talk to the builder. The site contractor who finishes and disappears before the foundation crew has questions. The permit that sits unfiled while everyone assumes someone else sent it. Masizo Development closes those gaps by owning all of it: we take your project from raw lot to final inspection as one licensed general contractor (AZ ROC #336058 in Arizona, CA LIC #1107781 in California), on one contract, with one phone number that always reaches someone accountable. We've been doing it in Arizona for 28 years.

One builder
One Builder, From Lot to Keys
Ground-up construction has more moving parts than any remodel: land evaluation, plans, engineering, permits, site work, foundation, framing, roofing, mechanical systems, finishes, and a long parade of inspections. When those parts belong to separate companies, every handoff is a place for time and money to leak. When they belong to one builder, the schedule is one schedule, the budget is one budget, and a question at any phase has one answer.
That's the structure of every Masizo custom build:
- You own the lot; we build on it — or we help you judge a lot before you buy.
- We coordinate design whether you bring finished plans or a folder of ideas.
- We file the permits and schedule every city or county inspection ourselves.
- You sign one contract and get one written quote before work begins.
Your lot
Build on Your Own Lot
Raw land is rarely build-ready, and the Valley's land varies more than listings suggest. An infill lot in Gilbert or Tempe usually has water, sewer, and power at the line; a parcel out toward Queen Creek or San Tan Valley may need a well, a septic system, and a meaningful run of new utility line before a foundation is even possible. None of that makes a lot unbuildable — but all of it belongs in the budget from day one, not discovered at trenching.
So the first thing we do on every custom build is walk the land. We look at access for equipment, utility availability and distances, drainage and grading, and which jurisdiction — city or county — will govern the permits. Only after that site review do we talk seriously about plans, because the site decides more of the design than most buyers expect.
Thinking of Buying Land? Call First
The cheapest site visit we make is the one before you close escrow. If you're shopping for a lot, we'll gladly tell you what a given parcel will demand — well versus municipal water, septic versus sewer, county permitting versus city — so the purchase price and the real cost of building there can be weighed together. Plenty of good lots look expensive and aren't; some bargains are bargains because of what's missing underground.
Design paths
Design Your Way: Bring Plans or Bring Ideas
There are two honest paths into a custom home, and we build both.
You have plans. An architect or designer has already drawn your home. We review the plans against your lot and the local code, price the build in a clear written quote, and construct what's drawn — flagging anything in the drawings that will cause trouble before it becomes expensive.
You have ideas. You know the rooms you need, the way you live, maybe a style you love — but nothing is on paper. We coordinate the design work within the project, so the people drawing the home and the people building it are on the same team from the first sketch. That connection matters: a designer who knows the builder's pricing in real time produces plans you can actually afford, instead of a beautiful set of drawings followed by a bruising round of cuts.
Either way, there's no requirement to hire an architect on your own before talking to us, and either way the project runs under a single contract.
Permits & inspections
Permits and Inspections, Handled Completely
Permitting a new home isn't one approval; it's a sequence of them, and the sequence differs between a city building department and a county one. Submittals get reviewed, revisions get requested, and once construction starts, the work can't advance past certain points until an inspector has signed off — foundation before it's poured over, framing before it's covered, systems before the drywall goes up. A single missed or failed inspection can idle a job site for weeks.
We run that whole process. We prepare the permit package, respond to plan-review comments, schedule each inspection to land when the work is ready for it, and are on site when the inspector arrives. You'll hear from us as each milestone passes — and at the end, it's our job to secure the final sign-off that makes the house legally yours to occupy.
The build
The Build, Phase by Phase
Once permits are in hand, the project moves through the same disciplined order every time: site preparation and grading; foundation; framing, which is the first week the house stops being abstract; the roof, which dries the structure in; the systems rough-in — electrical, plumbing, and HVAC threaded through the open frame; insulation and drywall; and finally finishes, from flooring and cabinetry to fixtures and paint. Throughout, you get regular updates tied to real milestones, and changes along the way are priced in writing before anyone acts on them — because "we'll settle up later" is how custom builds turn hostile.
The last step is a walkthrough with you, room by room, after the final inspection has passed. Then keys.
Where the money goes
What Actually Drives the Cost of a Custom Build
We don't publish price-per-square-foot figures, because on custom work they mislead more than they inform. What we can tell you is where the money genuinely goes, so the conversation at your lot starts honest. The site comes first: a parcel that needs a well, septic, long utility runs, or significant grading carries real cost before the house itself begins, while a serviced infill lot spends that same money above ground. The structure's complexity matters more than its size — a simple roofline and an efficient footprint build for less than the same square footage arranged in wings and angles. Then come the selections: windows, cabinetry, counters, flooring, and fixtures span enormous ranges, and this is where owners hold the most control over the final number. Our written quote breaks these layers apart instead of burying them in one figure, so when you choose, you're choosing with your eyes open.

Good to know
Custom home questions, answered.
Will you build on a lot I already own?
Yes — building on your lot is the core of what we do. The first step is a free visit to the property, where we check access, utility availability, drainage, and which jurisdiction's rules apply. Those answers shape the plans and the budget, so we insist on seeing the land before anyone commits to a design.
Can you look at a lot before I buy it?
Please ask us to. A lot that needs a well, a septic system, or a long utility run is a very different project from one with city services at the property line, and the listing won't always make that obvious. A short conversation before you sign can save you from buying a problem — or confirm you've found a good one.
Do I need to hire an architect before calling you?
No. Some clients arrive with finished plans, and we build from them. Others arrive with a sketch, a Pinterest board, or just a list of rooms — and we coordinate the design work as part of the project. Either way you sign one contract, with one company responsible for the result.
Who handles permits and inspections?
We do. We prepare and file the permit package with your city or county, then schedule and attend every required inspection through final sign-off. A missed inspection can stall a build for weeks, so we treat the inspection calendar as part of the construction schedule, not an afterthought.
Where do you build?
Across the Phoenix Valley — we're based in Gilbert and build throughout Gilbert, Mesa, Chandler, Queen Creek, San Tan Valley, Tempe, Scottsdale, Phoenix, Fountain Hills, and Paradise Valley. That range includes everything from city infill lots to county land in the Queen Creek and San Tan Valley area, and the permitting differences between them are ground we cover week in, week out.
Are you licensed and insured?
Yes. Masizo Development holds Arizona general contractor license AZ ROC #336058 and California license CA LIC #1107781, plus a separate Arizona restoration license (AZ ROC #347030), and we're insured. We've been building in Arizona for 28 years. You can verify our Arizona licenses directly with the Registrar of Contractors.
What happens at the free consultation?
We meet you at the lot. We walk it together, talk through what you want to build, flag anything about the site that will affect cost or design, and explain the path from where you stand to move-in. Afterward you get a clear written quote — not a teaser number that grows later. Call (602) 909-7630 to set it up.
