What are the fees for issuance of an IRC residential project (building) permit?
The following fees are required for the permitting of projects for 1-and 2-family residential buildings, townhouses, and associated accessory buildings. These fees help off-set the time and travel for field inspectors who are working to ensure the contractor and/or owner has clear direction on how to meet the requirements of the code and that the project does not experience delays or additional costs because of preventable issues during the construction process.
Work beginning prior to issuance of a permit will occur a penalty of an additional 100% of the calculated permit fee (double fees). Trade work performed without permit may result in the building project permit being locked until the appropriate permits are issued.
