Quick answer

Ann Arbor issues a swimming pool permit through the Building Department and prices above ground pools as a flat $125 building permit line item. The fee schedule footnote makes clear that the pool permit does not cover the wiring or the water connections: separate plumbing and electrical permits are required, and the electrical schedule carries its own swimming pools, spas and hot tubs line. Pools are also treated as accessory buildings under the zoning ordinance, so accessory building setback, height and rear open space limits apply. The city publishes no size, depth or volume exemption for residential pools.

How to apply in Ann Arbor

A residential pool permit application covers both construction and safety: a scaled site plan, structural plans for the pool, a barrier plan showing how the pool will be enclosed, and an electrical plan covering bonding and the equipment disconnect.

What most pool permit applications include:

  • Pool and spa design and construction fall under the residential code chapter that folds in the swimming pool and spa code, and permit review checks plans against that chapter (IRC R326).
  • The site plan must show pool equipment such as pumps, filters, and heaters set back at least 36 inches from the outside of the required barrier (ISPSC 305.2.9).
  • For an in-ground pool, engineered structural plans covering the shell and reinforcing steel, with the responsible structural engineer's license information, are a standard part of the submittal (per official pool submittal checklists).
  • A barrier plan identifying the fence, pool structure, or dwelling wall that will enclose the pool must be submitted and must comply with the code's barrier chapter (ISPSC 305).
  • Electrical plans must show the pool's equipotential bonding design, since the shell, perimeter surfaces, and metal fittings within 5 feet of the water must all tie into a common bonding grid (NEC 680.26).
  • The electrical plan must also show a disconnecting means for the pool equipment that is readily accessible and within sight of the equipment (NEC 680.13).

Inspections and closing out your permit

Pool inspections track the concrete pour: the steel and bonding grid are checked before gunite or shotcrete goes in, bonding is checked again before decking is poured, and the permanent barrier and remaining electrical work are checked at final before the pool can be filled and used.

  1. Before gunite or shotcrete is sprayed, the inspector checks the rebar against the engineered plans and confirms the equipotential bonding wire is stubbed out and tied into the steel, since it will be buried in concrete afterward (NEC 680.26).
  2. A bonding inspection separately confirms coping, decking, ladders, handrail cups, and any other metal within 5 feet of the water are tied to the bonding grid, and it must pass before coping is installed (NEC 680.26).
  3. A temporary barrier at least 4 feet high must enclose the site from the moment excavation starts until the permanent barrier is finished, and inspectors check for it throughout construction (ISPSC 305.1.1).
  4. A pre-plaster inspection confirms the circulation equipment's electrical work is installed and all bonding is complete before the pool's interior finish goes on (NEC 680.26).
  5. At final inspection the permanent barrier is checked against the code's requirements and the equipment and cover-mechanism bonding must be complete before the pool can be filled and used (ISPSC 305, NEC 680.26).

Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Ann Arbor permit portal or by phone at 734.794.6263 ext. 0.

Can a homeowner pull a pool permit themselves in Ann Arbor?
Under Michigan law (MCL 339.2403(b), (c); MCL 339.2401(a)(iii), (b)(ii)(A); MCL 339.5737(3)(g); MCL 339.6107(2)(d); MCL 339.5819): Yes. A Michigan homeowner may pull the building permit and do the work on their own home without a residential builder license, because the licensing article both defines the trade to exclude them and exempts them outright. MCL 339.2401(a)(iii) says a residential builder is a person that erects a residential structure except for the person's own use and occupancy on the person's property, and MCL 339.2403(b) exempts an owner of property with reference to a structure on the property for the owner's own use and occupancy. Own use and occupancy is the condition, so the exemption does not cover building to sell, and MCL 339.2403(c) limits owners of rental property to maintenance and alteration of that property. The statute sets no cap on how many times a homeowner may use the exemption; the only frequency rule in the article catches purchase, substantial rehabilitation, and resale of the same structure more than twice in 1 calendar year, and MCL 339.2401(b)(ii)(A) exempts work for the person's own use and occupancy from even that. Homeowners can also pull their own trade permits: electrical work in a single family home and accompanying outbuildings owned and occupied or to be occupied by the person doing the work (MCL 339.5737(3)(g)), their own plumbing, building sewer, or private sewer in their single-family dwelling if a permit is secured (MCL 339.6107(2)(d)), and a heating or refrigerating system if the owner affirms in the permit application that they are or will become the owner and occupant (MCL 339.5819). Confirm how Ann Arbor applies this before you apply.
