Troy, MI Home Business: Zoning & Home Occupation Permits (2026)

10 of the Chapter 39 Zoning Ordinance lists ten standards, A through J, that every Troy home occupation must meet. The use must stay clearly incidental and secondary to the dwelling's residential purpose (A) and cannot change the structure's character, appearance, or trigger any interior or exterior alteration uncommon to residential buildings (B). It cannot create a nuisance from noise, vibration, glare, fumes, odor, electrical interference, or fire hazard (C), and cannot push sewage or water use above what a typical single-family home generates (D).

No employees are allowed besides family members residing in the unit (E), and the business must operate entirely inside the dwelling or an accessory building with no outside display (F). Sections G through J add the traffic, signage, retail-sales, and outdoor-storage limits covered elsewhere in this Article. The citywide use table classifies 'Home occupations' with an 'A' designation, meaning accessory use permitted by right, across the R-1A through R-1E, RT, MF, UR, and MHP residential districts, though it is marked 'NP', not permitted, in districts such as CF and GB. 10 lists home occupations among the categories eligible for the Zoning Administrator's administrative plan review instead of full site plan approval.
