Installing a Swimming Pool, Spa, or Hot Tub

Installing a Swimming Pool, Spa, or Hot Tub

Your swimming pool, hot tub, or spa requires permits and inspections in order to ensure that it is safe for your enjoyment. Installation of swimming pools, spas, and hot tubs are required to comply with the 2021 International Swimming Pool and Spa Code (ISPSC) and Carroll County amendments. We encourage you to review our Pool Barrier Guidelines before applying for a permit.

Note: The site of the pool will need to be approved by the Carroll County Zoning Administration and the Carroll County Health Department to ensure that the proposed structure is a sufficient distance away from septic systems, water infrastructure, etc. For help with site selection, please contact:

Carroll County Zoning Administration 410-386-2980
Carroll County Health Department 410-876-1884

Permits Required

Your swimming pool will require a building permit and an electrical permit. Please see the list below for the documents required for your permits. The pool contractor is required to fill out and sign the Pool Enclosure Affidavit requiring a pool barrier be erected before water can be added to the pool. After the building permit is filed, your licensed electrician will need to submit an electrical permit application.

Your hot tub or spa only requires an electrical permit. If installed on an existing deck, structural details of the deck shall be submitted and will be evaluated. A building permit will be required if additional support is needed.

Permit Process

Many factors affect the speed with which your application(s) are approved. For best results, it is critical that you carefully review your application and design documents prior to submission to ensure that all necessary documents are included and that the design is compliant with the county code. Normally, permits can be issued within 10-15 business days if the application is complete, accurate, and code-compliant.

Note: Electrical permits for spas and hot tubs can be applied for, processed, and issued on the same day.
