Second story additions in Phoenix
When the lot is full, the way to grow is up. A second story asks the most of an existing house, and it is the work our KB-1 Dual license covers. We tie in the stairs, wiring, plumbing and HVAC so the new floor feels original, under a roofline that fits the street.
Room additions and primary suites
If the lot has room, building out is simpler and easier to live with. We take on the bigger ones. Think a primary suite with a full bath and closet, a great room or a multi-generational wing. If it means removing a load bearing wall to join old and new, it is part of the same job.
How an addition gets built with Radiant
Honest feasibility first
We walk the house and lot and hear what you need. Then we tell you if it fits the structure, the setbacks and the budget. If a smaller addition would serve you better, we say so.
Engineering and permits
Every structural change gets stamped engineering. We pull permits under ROC #367703, and you can look up our license yourself.
The build, communicated
You talk to Shane the whole way. He brings five years of hands-on experience. Trusted subcontractors do the work, and Radiant backs all of it. If an older wall or slab hides a surprise, you hear the same day, with options.
Tie-in, finish and final walk
The new space is finished to match the old, inside and out. We walk it with you room by room. We are done when you can't find anything left to fix.
Radiant is a faith-based company, named for Psalm 34:5: "Those who look to him are radiant." On your addition, that means telling you the truth about the numbers and showing up when we say we will. We treat your home like it belongs to people we care about. If your family is carrying something heavy during the build, we would be honored to pray for you.

Home addition questions we hear most
Can my house support a second story addition?
Many Valley homes can. An engineer checks the foundation, framing and soil first. Some need reinforcing, and some suit a partial second story. You'll know which before you pay for full plans.
How much does a home addition cost in Phoenix?
It depends on what you add and what the house must carry. A second story costs more per square foot than building out. We give firm numbers after a walkthrough and an engineer's look.
Do I need a permit for a home addition?
Yes, every time. Phoenix and nearby cities require plan review and inspections, and we pull every permit under ROC #367703. Unpermitted work surfaces at sale or appraisal and costs far more to fix.
Can we live in the house during the addition?
Usually, yes. A ground-floor addition stays outside your walls until the tie-in. A second story is harder, with loud, dusty weeks while the roof comes off. We plan around your family and warn you ahead.
How long does a home addition take?
Design, engineering and permits usually take a few months. The build runs a couple of months for a simple ground-floor addition and longer for a second story. You get a real schedule once plans are approved.
