Do you need a permit to coat a garage floor in Eagle?
In Eagle, grinding, crack filling and coating an existing garage floor is finish work, which doesn't need a building permit. Eagle City Code 7-1A-2 adopts the residential code the State of Idaho uses, which is the 2018 International Residential Code today, and Eagle's local changes in 7-1A-4 leave the Section R105.2 exemption for "painting, papering, tiling, carpeting, cabinets, counter tops and similar finish work" in place. The code doesn't name floor coatings, and the city's own advice is never to guess, so call the Eagle Building Division at 208-489-8760 if your project includes anything beyond the coating, like structural repairs, wiring or plumbing.

Grinding dust and rinse water in Eagle
Eagle doesn't have a separate stormwater discharge ordinance, but Eagle City Code 4-1-4 makes it unlawful to create a nuisance in streets, gutters or storm drains, and section 4-1-1 lists paint and other hazardous materials as nuisance materials. Section 5-2-2 also bans sweeping dirt from inside a building out onto the street.

Quiet hours in Eagle
Eagle City Code 4-9-3 bans loud or offensive noise from machinery and similar sources between 10 p.m. and 8 a.m., but construction noise can start at 7 a.m. Monday through Friday, or 6 a.m. in June, July and August. There's no early start on weekends, so loud work waits until 8 a.m. on Saturday and Sunday.
Winter roads and your garage floor
The City of Eagle says the Ada County Highway District (ACHD) is responsible for removing snow on public roads, and property owners are responsible for clearing the sidewalks in front of their homes. 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 Eagle?
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.
