Summary

In the townships Olmsted County zones directly, a private swimming pool is an accessory use allowed in any residential district, but Section 10.23 attaches conditions and Section 3.06 requires a Zoning Certificate from the Zoning Administrator before it goes in the ground, confirming the pool meets the ordinance's distance and fencing standards.

These county ordinances apply to unincorporated areas of Olmsted County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Swimming pools shall be allowed in any Residential Zoning District as an accessory use and subject to the following conditions and requirements... It shall be unlawful to use, occupy or permit the use or occupancy of any building or premises or part thereof, hereafter, created, erected, changed, converted, altered, or enlarged in its use or structure until a zoning certificate shall have been issued by the Zoning Administrator stating that the use of the building or land conforms to the requirements of this ordinance.
