Can I run water, power, and plumbing to my detached garage in Royal Oak?
Be careful here. Royal Oak bars an accessory building from combining utility services in a way that makes it easily convertible to habitable space (§ 770-22A(11)). This is the city's anti-conversion rule. A detached garage with power, water, sewer, and a finished interior starts to look like a future apartment, and the code is written to stop that before it is built.
The rule targets the combination, not any single service. The exact line between an allowed workshop hookup and an easily convertible space is a city call, not something the text spells out.
A detached unit could not become a dwelling anyway. Royal Oak permits no general accessory dwelling units, and senior accessory housing must be within or attached to the house (§ 770-71).
Describe your planned hookups to the planning division at 248-246-3280 before pulling permits.
