Choosing the Right Slab Thickness
Slab thickness for a garage comes down to load. 4 inches handles everyday passenger vehicles in most residential garages, while a heavy truck, a vehicle lift or regular equipment storage usually calls for 5 to 6 inches with added reinforcement. Finishing a basement too? Our Basement Floors page covers that job.

Garage Slab Requirements in Middletown
Garage slab requirements in New Castle County include air-entrained concrete: the county’s inspection checklist reminds contractors that garage slabs and exterior concrete must be air-entrained under IRC 402.2. Air entrainment puts tiny air bubbles in the mix, which gives water room to expand when it freezes. It’s a fair question to ask on any garage floor quote you’re comparing.
The Town of Middletown requires a building permit for any accessory structure, garages included, through its License and Inspection Department at Town Hall.
Middletown requires a town building permit for a garage, issued by the Permits, Licensing and Inspections office at Town Hall within about 10 business days. The office’s review also checks the flood zone and the town’s water resource protection areas.
The town builds to the 2024 International Residential Code, and detached garages need a 5-foot side and rear yard.
