Application Process

1. Confirm whether the property is within Gastonia city limits and whether a city zoning permit or land development review is required before county building submission.
2. Use the county Permit Applications page to select the correct residential, commercial, demolition, trade, pool, accessory structure, or manufactured home package.
3. Assemble the required forms, plans, valuation information, and any outside approvals noted by the county, including city zoning approval where applicable.
4. Submit the application and attachments through Gaston County Citizen Self Service or follow county instructions for manual submittal assistance.
5. County staff performs plan review and will assess applicable permit, technology, and review fees; Gastonia zoning or development approvals may need to be completed before issuance.
6. Pay fees. County issues the building permit after approvals are complete.

General Requirements

County permits are required for building, electrical, plumbing, mechanical, demolition, pool, deck, detached structure, manufactured home, and similar work covered by the county permit packages and state code.
