802.1.4.1 Permit required. A plumbing permit is required for the recirculated water distribution piping, the filter, the circulating pump, and the potable water fill line.

Full Breakdown
Section 8-5-11 of Detroit's Building Code adds a local provision to the Michigan Plumbing Code requiring a plumbing permit for a private residential pool's recirculated water distribution piping, filter, circulating pump, and potable water fill line. If the pool is instead filled with a garden hose, the hose bibb must have a vacuum breaker installed, and that installation likewise needs its own permit. The Buildings, Safety Engineering, and Environmental Department (BSEED) issues these permits and inspects the work before use: separate from any zoning or fencing rules that also apply to a backyard pool.
Violations & Fines
Installing a pool's water system without the required permit is a plumbing code violation; Detroit can fine up to $500 and jail up to 90 days per day the violation continues (Code § 108.4(c)).
