Do you need a permit to coat a garage floor in Meridian?
Grinding, crack filling and coating an existing garage floor in Meridian is covered as finish work, which doesn't need a building permit. Meridian adopts the 2018 International Residential Code in Meridian City Code 10-1-1, and the code's list of work exempt from permits (Section R105.2) includes painting, tiling, carpeting and similar finish work, a part Meridian did not change. The city's own residential Do I Need a Permit? handout also lists interior carpet or flooring as work that needs no permit. Floor coatings aren't named word for word, so call Meridian Building Services at (208) 887-2211 to confirm for your project, especially if it involves slab, structural, plumbing or electrical work.

Grinding dust and rinse water in Meridian
Meridian's nuisance code makes it illegal to create a nuisance in streets, gutters or storm drains, and it counts paint, oil and fuel as nuisance materials (Meridian City Code 4-2-1 and 4-2-4). The storm drains belong to the Ada County Highway District, so keep grinding slurry, coating leftovers and rinse water on your property and out of the gutter.

Quiet hours in Meridian
Meridian's noise rule (City Code 6-3-6) bans noise you can hear 50 feet or more away between 11 p.m. and 6 a.m., plus noise that unreasonably disturbs neighbors at any hour. It doesn't set separate construction hours or a different weekend schedule.
Winter roads and your garage floor
The Ada County Highway District maintains Meridian's public streets, and the Idaho Transportation Department handles the state highways and freeways. 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 Meridian?
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.
