Emerald Isle Construction is a locally owned general contractor serving Kuna, Idaho, where most requests are remodeling: kitchens, bathrooms and basements in houses only a few years old. It also builds additions and custom homes, and handles the City of Kuna's own permit process.
Three kinds of work, each with its own page, because each plays out differently here. Start with the one that matches your project.
This is the work Kuna asks for most. The city added 92 new homes in August 2026 alone, and the first phases of developments like Falcon Crest, Ashton Estates, Memory Ranch and Paloma Ridge are now old enough that owners want the kitchen, the bathrooms and the basement finished to their own standard rather than the builder’s. Almost all of it is permitted work through the city, and we handle that.

Kuna lots often allow building out rather than up, which is usually the simpler addition — provided setbacks and easements allow it, and we check both before design. Any addition to an existing home is a permitted project with the city, and if it adds plumbing or moves the mechanical system, those are permits too.

New construction in Kuna is mostly happening inside platted subdivisions rather than on scattered lots, so a custom build here usually starts with a lot in a development that is still permitting. The city’s own utilities — water, pressurized irrigation and sewer — reach those lots, which removes the well-and-septic questions that come up in some neighboring towns.

Kuna counted 24,011 residents in the 2020 Census, and the Census Bureau ranked it the eleventh fastest-growing city in the United States among cities over 20,000 for the year to July 2025. Three things follow from that for anyone building here.
Kuna is in Ada County, but permits inside the city come from the City of Kuna’s own Building Department at City Hall, 751 W. 4th Street, Monday to Friday, 8 am to 5 pm. Permits and inspections run through the city’s online portal. Inspection requests received by 4 pm are scheduled for the next business day; a permit must be picked up within 180 days of issue and work must begin within 180 days or it is void. The city builds to the 2018 International Residential Code. The full list of what needs a permit is on the remodeling page; the short version is that anything touching plumbing, wiring, mechanical or structure does, and so does installing a fence.
Kuna owns and operates its own water system — wells, storage tanks, and a separate pressurized irrigation supply — and its own wastewater system, with two treatment facilities including a membrane bioreactor plant on the north side. For a builder that means one utility to deal with rather than a patchwork of districts, and it means a property still on septic that connects to city sewer must abandon the septic system to Idaho DEQ requirements. See the City’s wastewater page.
The City publishes a monthly building permit report. August 2026’s runs to 626 permits, 92 of them new homes, in Linrock, Memory Ranch, Paloma Ridge, Sabinos Rocky Ridge, Ewing Meadows, Valor Golf Village, Bellaro Springs, Riverton, Valor West, Journeys End, Lugarno Terra North, Ashton Estates, Falcon Crest and Crimson Point. Several are on their seventh and eighth phases. That is the map of where Kuna is building now — and, a few years on, where it will be remodeling.

Every project runs on the same standards: quality materials, detailed execution, and open communication. Clients count on reliable timelines, transparent budgets, and a straight answer when something changes.
We are locally owned and work across the Treasure Valley, Kuna included. That matters as a practical thing rather than a slogan: we already know which desk a Kuna permit lands on, when to book the inspection so the schedule holds, and which questions to ask about a lot before anyone falls in love with it.

Yes — south of Meridian. But building permits inside the city limits come from the city, and so do water and sewer.

Several are on their seventh and eighth phases.
Yes, both, city-owned and city-operated, including pressurized irrigation water. What that means for adding plumbing in a remodel is covered on the remodeling page.
