Do you need a permit to coat a garage floor in Kuna?
In Kuna, grinding, crack filling and coating an existing garage floor is covered as finish work, which doesn't need a building permit under the International Residential Code. Kuna adopts the IRC as adopted by the State of Idaho with no local amendments (Kuna City Code 4-1-1-1), so Section R105.2's exemption for painting, tiling, carpeting and similar finish work applies as written. Kuna's code does require a permit to erect or alter a building (4-1-3), and floor coatings aren't named in either rule, so call the Kuna Building Department at (208) 922-5546 to confirm for your project.

Quiet hours in Kuna
Kuna's quiet hours run from 11 p.m. to 7 a.m. every day (Kuna City Code 10-6-3), and the city's Building Department says no construction during those hours. There's no separate weekend rule.
Winter roads and your garage floor
The Ada County Highway District maintains public streets in Kuna, and the Idaho Transportation Department handles the state highways. ACHD says it sprays liquid magnesium chloride on priority roads before storms so snow and ice don't bond, and spreads road salt and a salt and sand mix.
All of that rides into the garage on your tires and melts on the slab. The Federal Highway Administration says chemical deicers can make freeze and thaw damage to concrete worse, that surface scaling is the most common damage they cause on slabs, and that magnesium chloride and calcium chloride raise the most concern. A coated floor gives the melt a sealed, non porous surface to sit on instead of bare concrete, so you can squeegee it out the door.
New build in Kuna?
Polyrez, the coating system we use, says new concrete needs to cure at least 28 days before it’s coated, and the slab, the air and the material all need to be between 50°F and 80°F while it goes down. The Federal Highway Administration also recommends letting new concrete dry at least 30 days before deicers hit it. Tell us your closing date and we’ll plan the install around it.
