Star has gone from a small farm town to one of the fastest-growing cities in Ada County, and it still has both halves of that in its building stock — new subdivisions going in alongside working acreage and older farmhouses on generous parcels.
That mix is why so much of our work here is outbuildings and acreage construction: RV shops, detached garages, equipment storage, and custom homes on land people bought specifically for the room.

What we find in Star homes
The great majority of Star’s housing is recent subdivision construction — well-framed two-story and single-level homes from roughly 2005 onward that need layout and finish work rather than repair. Around and between those subdivisions sit older farmhouses and ranch homes on acreage, some dating to the mid-century and earlier, which typically need systems work, insulation, and structural attention to previous additions. The acreage parcels are where the interesting projects are: shops, barns, ADUs, and custom homes with real room to site them.
Permitting and planning in Star
Permits run through City of Star Planning & Zoning, with Ada County handling unincorporated parcels — and around Star the city limits are genuinely irregular, so confirming the jurisdiction from the parcel record matters more here than in most places. Irrigation easements are widespread across the surrounding farmland and routinely determine where a shop or second structure can sit. Parcels in the Boise River bottom may fall within mapped floodplain, which affects elevation and permitting for new structures. Acreage outside city services will need well and septic with district health approval.

Learn moreBuilding in Star: common questions
Can you build an RV shop on my Star acreage?
This is one of the most common projects we do out here. The two things that decide the design are the zoning height limit and the actual height of your coach — a Class A with roof air needs meaningfully more door clearance than a standard twelve-foot door, and that drives wall height and truss selection. We measure first and design to it.
Am I inside Star city limits or in Ada County?
Around Star that is a real question, not a formality — the boundary is irregular and a Star mailing address does not settle it. The two jurisdictions apply different standards to accessory structures and dwellings, so we confirm it from the parcel record before scoping anything.
Do you build custom homes on acreage in Star?
Yes, and it is a good share of our new construction. Expect the front end to include well and septic feasibility, power service, driveway and approach permitting, irrigation easement review, and floodplain checking if the parcel is in the river bottom.

“The finished work was excellent, delivered on time, and inside our budget. What more is there to ask?”
Our experience with GW Construction was outstanding from beginning to end. They were recommended to us by a real estate agent we trusted, who was helping us plan a remodel of a home we had just purchased. Past contractors had been hit or miss for us, so committing to a renovation north of $70,000 made us genuinely nervous. That changed at the first meeting. Derek listened carefully to what we wanted the remodel to accomplish and then carried the plan out faithfully. Just as valuable, he offered real insight where he saw a way to improve on our thinking, and told us plainly when an idea of ours was not economically sensible or carried a downside we had not considered. He was straightforward, transparent, and respectful throughout. Communication was excellent — calls, emails, and texts were returned promptly. He even introduced us to each of the subcontractors so we could build a relationship with them directly. Most importantly, the finished work was excellent, delivered on time, and inside our budget. What more is there to ask? Highly recommended.
Jack and Sue Serrino“He has completed more than 25 projects for my clients over the years, and I intend to keep sending them his way.”
Derek is far and away the best contractor I have worked with, and his ability to listen to my clients and respond to what they actually need has exceeded anything I expected. Being classically trained and professionally educated shows in the work. His grasp of both the practical and the possible means he handles small and large-scale jobs equally well, and there is genuinely nothing I would hesitate to refer to him. He has completed more than 25 projects for my clients over the years, and I intend to keep sending them his way.
