Adu Construction Tucson, AZ

Custom home construction in Tucson, Arizona from foundation through final inspection.

Local ADU Construction Expertise

In Tucson, accessory dwelling unit construction gives homeowners a proven way to add a complete second unit on your property. ADU construction in Tucson works with city-approved designs and handles all permits, inspections, and building codes so your casita meets current regulations.

How We Work

We build each ADU from the ground up with a clear process. You're involved at every phase so there are no surprises or hidden steps.

What's Involved

Design & Plans

We review your property and create a design that fits your lot size and Tucson's setback rules.

Permits & Approvals

We submit all paperwork to Tucson's Planning and Development Services and guide approvals through completion.

Foundation & Build

We pour the foundation, frame walls, rough in utilities, and install materials that meet Tucson building codes.

Finish & Inspection

City inspectors sign off at each stage. We finish interior, test all systems, and obtain the Certificate of Occupancy.

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

Our Services

We handle complete ADU construction from start to finish using proven methods and Tucson-compliant builds.

Detached Casita Builds

A detached casita sits separate from your main home and offers full independence for rental or guest use. A 650–1,000 sq. ft. casita in Tucson neighborhoods like Armory Park or Blenman-Elm works well on most residential lots.

We build the casita to code with a cool roof (required in Tucson), proper setbacks, and full electrical, plumbing, and HVAC.

Attached & Accessory Units

An attached ADU shares a wall or roof with your primary residence and uses existing utilities more efficiently. This option maximizes tight lots in areas like Civano or the northeast neighborhoods.

We design attached units to blend with your home's architecture while meeting all setback and height requirements.

Conversion & Renovation

If you have an existing garage, storage, or outbuilding, we can convert it into a permitted ADU. Many Tucson homeowners avoid rebuilding by converting existing structures to full dwelling units.

Conversions require new foundations or structural upgrades, kitchen and bathroom builds, and separate utility meters.

Why It Matters

An ADU adds real value and flexibility to your Tucson home.

Compliance & Peace of Mind

Tucson ADUs can be up to 75% of the primary home's square footage, capped at 1,000 sq. ft., with all lots allowed at least 650 sq. ft. We stay current with every code update so your ADU passes inspection on first submission.

Tucson now allows multiple ADUs per lot under recent amendments. We help you understand what qualifies for your property.

Rental Income & Flexibility

An ADU gives you income from long-term tenants or guest stays, covers mortgage payments, or supports aging parents on-site. Tucson homeowners use casitas for family reunions, adult children, or steady rental cash flow.

A permitted unit also increases property value and attracts serious buyers if you ever sell.

Serving Tucson and Surrounding Areas

We build ADUs across every Tucson neighborhood, from the central urban areas to the foothills.

Central & East Tucson

Neighborhoods like Armory Park, Blenman-Elm, and Civano have smaller historic lots and active communities. We've completed dozens of ADUs in these walkable areas where every square foot counts.

North & Foothills

The Catalina Foothills and northeast suburbs offer larger lots and scenic views. We design casitas that complement mountain landscapes and respect neighborhood aesthetics.

Frequently Asked Questions

Common questions about ADU construction in Tucson

Can I build an ADU on any Tucson residential lot?

Tucson permits at least one ADU per residential lot. Lot size and zoning affect the maximum square footage allowed, but nearly every homeowner can add at least a 650 sq. ft. unit.

What does Tucson require for ADU construction?

ADU height must not exceed 12 feet or the height of the primary residence, whichever is less. Front setback is determined by the existing residential structure; side and rear setbacks require a minimum distance of 5 feet from property lines. Builders must use durable materials and comply with building codes that emphasize safety, durability, and compatibility with the main residence.

How much does an ADU cost in Tucson?

Cost depends on size, lot conditions, finishes, and whether you're building new or converting. Contact us for a detailed estimate after we review your property.

Do I need a permit for an ADU in Tucson?

Yes. Property owners must submit ADU plans to Tucson's Planning and Development Services Department for review to ensure all ADUs meet local zoning, safety, and building standards.

Can I rent out an ADU in Tucson?

Yes. Long-term rentals are permitted under Tucson law. Short-term rentals have specific owner-occupancy requirements—we explain all rules during your consultation.

Does an HOA prevent me from building an ADU?

City law permits ADUs on residential lots, but HOA rules may apply. A homeowner within an Association is still subject to the Association's Governing Documents; city ordinances allowing ADUs do not supersede HOA rules that prohibit or restrict them. Review your governing documents or contact your HOA.
