Who we are
Most construction headaches aren't about craftsmanship — they're about handoffs. The framer blames the designer, the roofer blames the framer, and the homeowner carries a phone list nobody wants to answer. Masizo was built against that model. We've spent 28 years in Arizona as a single point of responsibility: one company that designs with you, pulls the permits, builds the structure, finishes the interior, and stands behind the result. The same discipline runs our restoration side — because a company that can rebuild your house is the right company to dry it out, and you shouldn't need two contracts to get from flood to finished drywall.
We're Masizo Development LLC — Arizona general contractor license AZ ROC #336058, Arizona restoration license AZ ROC #347030, and California license CA LIC #1107781 for select out-of-state projects. IICRC certified. Insured. BBB accredited, A+ rated. Those credentials are on every page of this site because they're the difference between a contractor and a guy with a truck.
Build
Ground-up builds, from design coordination through final walkthrough. Permits and inspections handled, structure engineered for the desert, finishes at the level you actually pictured.
Design-to-build · Permits & inspections · Finish carpentry
Detached guest houses, attached in-law suites, and garage conversions, with the permit and zoning work carried for you. Arizona law now requires most Valley cities to allow them — our Arizona ADU law guide explains exactly what you can build on your lot.
Zoning & permits · Detached or attached · Interior buildout
Bedrooms, living space, and expansions with real foundations and engineered structure, tied into your home's electrical, plumbing, and HVAC so the new square footage never feels bolted on.
Foundations · Framing & roof tie-in · HVAC & finish
Remodel
Whole-house transformations: layout and structural changes, systems brought up to date, and every finish selected on purpose.
Structural changes · Layout & systems · Full finish
Cabinetry, countertops, appliance and electrical work, flooring, lighting, backsplash — the room your house actually revolves around, rebuilt to work.
Cabinetry & counters · Electrical · Lighting & tile
Shower and tub installations, tile and vanities, and the plumbing and ventilation work that decides whether a bathroom stays beautiful.
Showers & tubs · Tile & vanities · Plumbing & vent
Protect
Replacements, tile, shingle, and flat systems, leak repair, and inspections — built for monsoon season and a hundred-and-fifteen-degree summer.

How it works
Every project starts with a no-cost, on-site consultation. We look at the real conditions — not photos, not guesses — and listen to what you're actually trying to get out of the space.
You receive a detailed proposal: scope, timeline, and transparent pricing. No vague allowances, no hidden line items, no number that mysteriously grows once the walls are open without a conversation first.
Permits, city coordination, scheduling, trades, inspections, communication — our job, start to finish. Your job is decisions and walkthroughs. A bathroom runs weeks; a custom home runs months; either way, you'll know the plan before we swing a hammer.

Why Masizo
We started building here in 1998. The contractors who last this long in this market are the ones whose work holds up — and whose phone gets answered.
Arizona general (AZ ROC #336058), Arizona restoration (AZ ROC #347030), California (CA LIC #1107781). Look them up — we'd rather you verify than take our word.
The restoration industry's own certification standard, real insurance, and an accreditation that has to be earned and kept.

Good to know
We're based in Gilbert and work across the East Valley and greater Phoenix metro — Gilbert, Mesa, Chandler, Queen Creek, San Tan Valley, Tempe, Scottsdale, Phoenix, Fountain Hills, and Paradise Valley. We also take on select projects in California under our California contractor license (CA LIC #1107781). If you're near but not in one of those cities, call us; the answer is usually yes.
Yes — and they start with a visit, not a phone guess. We come to your property, walk the project with you, and follow up with a written, no-obligation quote. You'll know the scope and the number before you commit to anything.
Yes. Masizo Development LLC holds an Arizona general contractor license (AZ ROC #336058), a separate Arizona restoration license (AZ ROC #347030), and a California contractor license (CA LIC #1107781). We're insured, IICRC certified for restoration work, and BBB accredited with an A+ rating.
It depends entirely on scope. A bathroom remodel is measured in weeks; a ground-up custom home is measured in months; everything else lands in between. What we promise on every job is a written timeline at the proposal stage — set before work starts, not discovered along the way.
Restoration is an emergency line for us, not a scheduling queue — we operate 24 hours a day, 7 days a week. Our IICRC-certified crew assesses the damage, stops it from spreading, documents everything, and works directly with your insurance company through mitigation and rebuild. One call at (602) 909-7630 starts it.
Always. Permit applications, plan review, coordination with city planning staff, scheduling inspections, and being on site when the inspector arrives — that's all part of what you hire a general contractor to carry. You will never be sent to a city counter to sort out your own project.
Service area
Home base is Gilbert, and most of our work is across the East Valley and Phoenix metro: Gilbert, Mesa, Chandler, Queen Creek, San Tan Valley, Tempe, Scottsdale, Phoenix, Fountain Hills, and Paradise Valley. Under our California license we also take on select projects out of state. See the full map and city list on our service areas page — and if your city isn't on it, call anyway; the East Valley doesn't have hard edges and neither do we.
