How Much Does It Cost to Add a Bedroom in Arizona?

Adding a bedroom is one of the smartest ways to grow your home’s value and livable space — especially in Arizona, where extra square footage can majorly bump resale. But what does it actually cost?
At KC KREW, we build and remodel homes across Scottsdale, Phoenix, and surrounding areas. Here’s what you really need to know.
Typical Cost to Add a Bedroom in Arizona
Most bedroom additions run between $200 and $350 per sq. ft.
So for a 12' x 12' (144 sq. ft.) bedroom, that usually means:
Finish Level Estimated Total
-Basic Build $28,000 - $35,000
Structure, drywall, basic flooring & electrical.
- Mid-Range $35,000 - $45,000
Upgraded flooring, trim, lighting.
- High-End $45,000+
Custom windows, built-ins, luxury fixtures.
What Drives the Price?
Key cost factors:
Foundation & excavation: Especially if your lot slopes.
Tying into existing HVAC & electrical: May require a panel upgrade.
Matching exterior finishes: Stucco, roofing, and paint to blend seamlessly.
Permits & plans: Usually $2,000–$5,000 in Arizona.
Who Pulls the Permits?
We do.
As your licensed Arizona contractor, KC KREW
handles:
-City permits & inspections
-Engineering or architectural plans if needed
-Scheduling all inspections so your project stays stress-free.
This keeps your addition legal & insurable,
and protects your investment long term.
Will It Pay Off?
Absolutely.
Going from a 2-bedroom to a 3-bedroom home often jumps your property class, meaning more buyers and higher appraisals.
Plus, you get extra livable space that’s custom to your lifestyle.
How Long Does It Take?
4–6 weeks for simpler builds
8–10+ weeks if you’re adding custom finishes, big roofline changes, or new HVAC zones.
Quick FAQs
How does financing work?
-Most of our clients use a HELOC (home equity line of credit) or cash-out refinance. We can also connect you with lenders.
Is it cheaper to build up or out?
-Usually building out is more cost effective — building up often means reinforcing your entire structure.
What happens if I build without a permit?
-You risk big fines & forced tear-outs. If that’s you — don’t stress. We can help get retroactive permits & inspections to fix it.
