Adu Construction Ahwatukee, AZ

Custom home construction services in Scottsdale for homeowners seeking quality and craftsmanship.

Local ADU Construction Expertise

In Scottsdale, accessory dwelling units (ADUs) unlock your property's full potential. Whether you need rental income, space for family, or a guest house, ADU construction in Scottsdale opens legal, practical options. We handle design, permits, and building so you don't navigate complex regulations alone.

How We Work

Your ADU project follows a clear, transparent process from initial consultation through final inspection.

We Start with Your Site

Every ADU begins with facts, not guesses. We evaluate your Scottsdale property for setback limits, utility connections, zoning compliance, and design fit within your lot size.

Scottsdale's regulations require separate metered electrical and gas lines for your ADU. We confirm your property can support these separate connections before moving forward. This upfront review prevents costly surprises.

We Design for Scottsdale's Code

Detached ADUs in Scottsdale must meet specific setback rules—typically five feet from side or rear lines. Attached ADUs have their own height and proximity standards. Our designs fit these rules precisely.

We handle architectural plans, structural engineering, and utility layouts. All drawings are pre-reviewed against Scottsdale's adopted building codes to reduce revision cycles.

We Secure Permits

Scottsdale requires a pre-application meeting, detailed plan submittals, and city staff review. We prepare all documents, manage back-and-forth communication, and shepherd your project through approval.

Once approved, you receive your permit and can break ground. We ensure every page of your permit is clear and ready for on-site inspectors.

We Build with Inspection Checkpoints

Construction includes scheduled inspections at foundation, framing, electrical, plumbing, and final stages. We prepare the site for each inspection and coordinate with the city.

Every step is documented. Your ADU is built to code and confirmed in writing by the city before we move to the next phase.

You Receive Your Final Permit

Once the final inspection passes, Scottsdale issues a Certificate of Occupancy. Your ADU is legal, insurable, and ready to use—whether as a guest house, rental unit, or family space.

You'll always know what's happening next—and when.

Our Services

We build all three types of ADUs allowed in Scottsdale, each with its own benefits and regulations.

Detached ADUs

Detached ADU in rear yard, meeting Scottsdale setback requirements

A detached ADU stands alone on your property—a true guest house or rental unit. Scottsdale allows placement in rear or side yards, with five-foot setbacks from property lines.

Detached units work well for families needing separate spaces, landlords seeking rental income, or homeowners in neighborhoods like Arcadia or Old Town looking to maximize usable property.

Attached ADUs

Attached ADU adjacent to primary residence

An attached ADU connects directly to your main house—an addition built under one roof. This type is ideal when lot size or shape limits detached placement.

Attached units share an exterior wall with your main dwelling. They're common in Scottsdale's established neighborhoods where lots are smaller, and they often cost less to build than detached units.

Affordable Detached ADUs

Affordable ADU project meeting income-based requirements

Scottsdale's zoning allows an additional third detached ADU on larger properties (one acre or more) if at least one ADU is deed-restricted for affordable housing. This supports Scottsdale's housing diversity.

We manage the legal requirements, affordability deed language, and income verifications so you can confidently build an affordable unit that benefits the community.

Why It Matters

ADUs solve real problems for Scottsdale homeowners while respecting neighborhood character.

Housing Pressure and Smart Solutions

Scottsdale faces significant challenges related to housing supply and affordability. ADUs offer a practical solution by allowing homeowners to convert existing spaces or build new structures on their property. This increase in supply can help meet the demand for housing without altering the character of established neighborhoods.

An ADU lets you stay in your Scottsdale home while adding flexible living space or income—without selling or moving.

Legally Protected Now

Scottsdale's zoning ordinance was amended in January 2026 to comply with HB2928. The new law expands the ability for ADUs to be built on residential lots. You have legal clarity—no more uncertainty about whether your city will allow an ADU.

Previous legislation restricted the building of ADUs within the operating vicinity of airports. However, the new law reduced the size of those restriction areas and thus expanded areas in Scottsdale where ADUs can be built. Most Scottsdale properties now qualify for ADU construction.

Serving Scottsdale and Surrounding Areas

We specialize in Scottsdale's unique zoning landscape and neighborhood contexts.

Scottsdale's Neighborhoods, Scottsdale's Rules

Scottsdale's zoning districts—like R1-43 and R1-190 residential zones—have specific setback, height, and utility requirements for ADUs. We know each zone's rules and design accordingly.

Whether your property is in the Foothills, Old Town, Arcadia, or Paradise Valley neighborhoods, we apply Scottsdale's Foothills Overlay and preservation requirements where they apply. Design that respects your area's character is always built in from day one.

Local Expertise You Can Trust

Scottsdale's code update just happened this year. Most contractors haven't caught up yet. We have. Our team navigates the new ordinance, knows the permit timeline, and coordinates directly with Scottsdale planning and building staff.

You get a partner who speaks Scottsdale's language and has already built ADUs under the new rules. That experience saves you headaches, rework, and wasted time.

Have Questions?

Get answers to the most common questions about ADU construction in Scottsdale.

Can I build an ADU on my Scottsdale property?

If you own a single-family home in Scottsdale with an existing main house and your lot isn't in an airport restriction zone, you can likely build at least one ADU. We evaluate your property during a free site review to confirm eligibility.

What's the difference between attached and detached ADUs?

Attached ADUs connect directly to your main house; detached units stand alone. Detached units work better on larger or oddly-shaped lots. Attached units cost less and fit tighter properties. Both are fully legal in Scottsdale under current code.

Does Scottsdale require separate utilities for an ADU?

Yes. Scottsdale mandates separately metered electrical and gas lines for your ADU. Water and sewer use the main tap but split on private property. We design all utility layouts to meet these requirements.

Can I rent out my ADU?

Yes. Arizona law protects your right to rent your ADU as a long-term rental. Scottsdale allows short-term rentals too, but requires you to live on-site if you do. Check with your HOA, as some restrict rentals.

What are Scottsdale's setback rules for detached ADUs?

Detached ADUs in Scottsdale must be set back at least five feet from rear and side property lines. They cannot be placed in front yards. Our design process ensures your unit meets these setbacks exactly.

What inspections does the city require during construction?

Scottsdale requires inspections at foundation, framing, electrical, plumbing, and final completion stages. We schedule each inspection in advance and prepare the site so the inspector can verify compliance quickly.
