ADUs in Gilbert & Queen Creek: How Revival Contracting Can Add a Casita, Guest House, or In-Law Suite to Your Property

If you've been thinking about adding an accessory dwelling unit (ADU) to your Gilbert or Queen Creek home, there's never been a better time.
New Arizona law has made the process easier than ever — and Revival Contracting is ready to build it.

What is an ADU?
An accessory dwelling unit (ADU) — also called a casita, guest house, or in-law suite — is a self-contained living space built on the same lot as your primary home.
It has its own bedroom, bathroom, and kitchen, making it a fully independent unit that adds real value and real flexibility to your property.

In the East Valley, ADUs are surging in popularity. Whether you want to house an aging parent nearby, give an adult child their own space, earn rental income from a long-term tenant, or simply add versatile square footage to your property, an ADU delivers on every front.

Gilbert & Queen Creek ADU rules: what you need to know
Arizona passed landmark legislation (HB 2720 and HB 2928) that makes it easier for single-family homeowners to build ADUs. As of 2026, these "by-right" rules are fully integrated into local codes across Gilbert, Queen Creek, and the rest of the state.

Key rules for Gilbert & Queen Creek homeowners: 
You are generally entitled to build at least one attached and one detached ADU on your single-family lot. ADUs may not exceed 75% of your primary home's square footage, or 1,000 sq ft — whichever is smaller. Side and rear setbacks are a minimum of 5 feet. Your ADU can be rented long-term (90 days or more), but cannot be used as a short-term Airbnb-style rental in Gilbert. Queen Creek requires construction plans that include foundation, framing, elevations, and materials.

If your property has an HOA, their CC&Rs may still apply — Revival Contracting can help you navigate this.

Types of ADUs Revival Contracting builds
We design and build all major ADU types for East Valley homeowners. Every project starts with your goals and your lot — not a cookie-cutter floor plan.
DETACHED

• Backyard casita
  • A freestanding structure in your backyard.
  • Maximum privacy for guests, family, or renters. The most popular ADU type in Gilbert and Queen Creek.

ATTACHED

• Home addition ADU
  • Connected to your existing home with a separate entrance.
  • Ideal for multigenerational living with easy access between the units.

GARAGE CONVERSION

• Garage conversion
  • Transform an underused garage into a livable, permitted ADU.
  • A cost-effective way to add a full apartment to your existing footprint.

INTERIOR

  • Carve out a separate suite within your existing home — bonus rooms, over-garage spaces, and large floor plans are prime candidates.

Why build an ADU in the East Valley right now?
Gilbert and Queen Creek are two of the fastest-growing communities in the entire country. Land is being absorbed quickly, and both towns attract multigenerational families looking to stay close together without living under one roof.
An ADU gives you exactly that: proximity with independence.

Beyond family use, long-term rental demand in the East Valley remains extremely strong.
A well-built ADU can generate meaningful monthly income while significantly increasing your home's appraised value — often more than the construction cost itself.

And with Arizona's new by-right laws in place, you no longer need special zoning variances or neighbor approval. If your lot is zoned residential, you have the right to build.

Frequently asked questions about ADUs in Gilbert & Queen Creek

Yes — long-term rentals (leases of 90 days or more) are permitted. Short-term vacation rentals through platforms like Airbnb are not allowed under Gilbert's current rules.
Do I need my HOA's approval? 
State law does not override HOA CC&Rs. If your community has an HOA, we'll help you review the relevant rules before breaking ground.
How big can my ADU be? 
Up to 1,000 sq ft, or 75% of your primary home's gross floor area — whichever is smaller. On lots over one acre, additional options may be available.
How long does an ADU take to build? 
Most detached casitas take 4–7 months from permit approval to move-in, depending on size and complexity. Garage conversions and attached ADUs can be faster.
