Do you need a permit to coat a garage floor in Middleton?
Middleton adopts the International Residential Code as Idaho adopts it (City Code 4-1-2), which today is the 2018 edition, and Section R105.2 of that code lists "painting, papering, tiling, carpeting, cabinets, counter tops and similar finish work" as work that doesn't need a permit. Middleton's own permit rule (4-1-1) is broader, though. It requires a permit to construct, remodel, renovate or add to any structure over 200 square feet, lists only a few exemptions, and says to contact the city building official for other exemptions. Floor coatings aren't named either way, so call the Middleton Building Department at (208) 585-3133 before the job to confirm a coating on your existing garage floor doesn't need a permit.

Grinding dust and rinse water in Middleton
Middleton's code (8-1-19) makes it unlawful to discharge wastewater or other polluted water into any drop inlet, like a street storm drain, or any natural outlet in the city. Grinding slurry, coating residue and soapy wash water should be collected and thrown away, not washed into the street.

Quiet hours in Middleton
Middleton's noise code (8-1-5) says business noise that can be heard inside another home or 100 feet away is off limits from 10 p.m. to 7 a.m. Sunday through Thursday, and from midnight to 7 a.m. on Fridays, Saturdays and federal holidays. In June, July and August, the code says construction noise may start at 7 a.m. and has to end by 10 p.m.
Winter roads and your garage floor
Middleton's Public Works Department takes care of roads inside city limits, Canyon Highway District No. 4 handles roads outside the city, and ITD handles State Highway 44. The city has said its crews stockpile sand for intersections and start clearing snow and sanding intersections once about two inches of snow comes with freezing temperatures.
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 Middleton?
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.
