Key Differences
Cincinnati and Provo share a similar owner-occupancy framework for ADUs — both require the owner to reside in either the primary dwelling or the accessory unit (Cincinnati Municipal Code §1421-06(l); Provo City Code §14.30.030(4)(a)) — but they diverge sharply on parking. Cincinnati exempts ADUs from off-street parking requirements entirely (Cincinnati Municipal Code §1421-06(j)), while Provo requires at least four off-street spaces for the lot. Short-term rentals are permitted citywide in Cincinnati with a registration requirement (Cincinnati Municipal Code Chapter 856), while Provo bans short-term rentals outright in agricultural and residential zones (Provo City Code §6.33.020(2)). Home businesses are allowed in both cities. Provo confirms a Home Occupation Permit requirement (Provo City Code §14.41.020); Cincinnati's municipal code appears to allow home occupations by-right subject to standards (§1421-50), but whether a separate city permit or business license also applies has not been independently confirmed in this corpus — check with Cincinnati Development Services for the current requirement.
Cost Comparison
Cincinnati's ADU building permit fees run roughly $400–$2,500 based on construction value, with a total estimated fee burden of about $800–$4,000. Provo's ADU building permit fees are similarly based on construction value, typically $400–$2,000, plus utility connection fees, with the city's consolidated fee schedule (an external document) governing current totals. Both ranges are drawn from each city's cached fee schedule and should be confirmed with Cincinnati Development Services or Provo Development Services before budgeting a project.
Our Verdict
Cincinnati is the more accommodating city for an ADU rental strategy — no added parking requirement and STR use is permitted citywide with straightforward registration, whereas Provo requires four parking spaces and bans short-term rentals in residential zones entirely. Both cities require the owner to live in one of the two units, so neither is a pure investment-property play. If your priority is building an ADU without a parking mandate and keeping short-term rental as an option, Cincinnati is the stronger choice; Provo's rules work better if you're not pursuing STR income and can accommodate the added parking requirement.

Frequently Asked Questions
Does Cincinnati require extra parking for an ADU?
No. Cincinnati exempts accessory dwelling units from its off-street parking requirements entirely (Cincinnati Municipal Code §1421-06(j)). Provo, by contrast, requires at least 4 off-street parking spaces for a lot with an ADU (Provo City Code §14.30.030(5)).
Can I rent out my ADU short-term in Provo?
No. Provo prohibits short-term rentals in agricultural and residential zones under City Code §6.33.020(2), so an ADU in a residential zone cannot be used as a short-term rental.
Do I have to live in my ADU or my house in Cincinnati?
One or the other. Cincinnati requires the owner of the lot to maintain a residence in either the principal single-family dwelling or the accessory dwelling unit (Cincinnati Municipal Code §1421-06(l)).
Is a separate city permit required for a home business in Cincinnati?
Cincinnati's home occupation rules (Municipal Code §1421-50) appear to permit qualifying home occupations by right, but whether a separate permit or business license also applies has not been independently confirmed — check with Cincinnati Development Services for the current requirement. Provo confirms a Home Occupation Permit is required (Provo City Code §14.41.020).
