Answers from the rulebook for Aurora
Aurora’s own rules
Building permitRequired
Erecting, moving, adding to, or structurally altering a building inside Aurora city requires a zoning (improvement location) permit. This is the zoning permit, not the building-code permit, which was not located.
The zoning permit is issued by the planning director or designee under plot plan review or site plan review.
Under 152.295 a permit is also required before land is established or changed in use or character.
Under 152.296 a zoning permit application is made on a form prescribed by the plan commission.
Per 152.296 criteria, work must be initiated within one year of issuance or the permit expires; it must be substantially completed within two years.
“no building or other structure may be erected, moved, added to. or structurally altered, nor shall any building, structure, or land be established or changed in use or character without a permit.”
Certificate of occupancyRequired
Occupancy of buildings in Aurora city under the zoning code
The source states that failure to obtain a zoning permit and certificate of occupancy is a violation, which implies a certificate of occupancy is required; the issuing procedure and inspection steps were not located.
“failure to obtain a zoning permit and a certificate of occupancy shall be a violation of this subchapter and will be punishable under the provisions of this chapter.”
Local zoningPresent
Land inside Aurora city limits: Aurora city adopts and administers its own zoning code (Chapter 152 Zoning Code), which divides the city into zoning districts.
Chapter 152 also covers territory within the extraterritorial jurisdiction of the plan commission, which is outside city limits and is not answered by this claim.
The American Legal Publishing copy is stated to be current only through Ordinance 2022-016, passed 12-19-22; later amendments were not checked.
“for the purpose of this chapter, the city and the territory within the extraterritorial jurisdiction of the plan commission are hereby divided into eight categories of zoning districts as follows:”
