Determining Fees


Fees for most permits are calculated by determining the value added to the property or the cost of construction. This value is used with the fee tables as published in the appropriate code governing the work.

Flat Fees


There are some routine items that are “flat fee” permits such as fences, seasonal or temporary pools, and non-covered decks between 1-300 square feet in size.

How to get a Quote


We are happy to help estimate the permit fees for a project but until an application is submitted and reviewed an exact fee cannot be given. All fees are calculated by the building official.

Site Maintenance


The contractor will be responsible for all debris on the site and should take all necessary measures to ensure it does not blow away from the site. Subcontractors hauling debris will be required to cover all loads and a trash containment system is required at all sites, approved styles are:
  • Dumpster type container
  • Trailer
  • Fenced in containment area
Site maintenance will become a part of all inspections as well as inspection on a random basis.

The City of Johnston uses the National Weather Service’s 24 hour prediction to reflect when/how concrete may be poured as follows:

10° or below - No concrete may be poured
25° or below - Concrete must be covered for a minimum of 48 hours
