Frequently Asked Questions
Why do I need a building permit?
Building permits and inspections basically protect the consumer from unscrupulous contractors who may not build to the codes. They also help the do-it-yourself homeowner, who may not have a working knowledge of building codes, ensure that their building projects are completed safely and in accordance with current building codes.
When do I need a permit?
A permit is required for the erection, repair, alteration, improvement and addition of or to any building within the City. Permits are not required for ordinary maintenance or repair, unless the alteration changes the exterior lines or limits of the building, changes the number of living units within the building, or relates to the sanitary condition, which requires a building permit regardless of the cost of the improvement. Replacement windows do not require a permit. We do require a permit to put siding on your house. You do not need a permit to put a fence around your property, but you must ensure the fence lies within your property lines and that the fence complies with zoning regulations of your property.
Where do I get a plumbing permit?
All plumbing permits are obtained through the Clinton County Health Department located at 111 S. Nelson Avenue. Their phone number is (937) 382-7251.
What if we live outside the city limits of Wilmington?
Building permits and zoning issues outside of the city limits are under the jurisdiction of the Clinton County Building & Zoning Department. They are located at 111 S. Nelson Avenue, and their phone number is (937) 383-2054.
Do I have to go to Columbus to get a State Permit for a commercial building?
No. The City of Wilmington Building Department became a State of Ohio Certified Building Department in 1991, which enables us to issue commercial building permits and perform all inspections for those permits, except plumbing, which is handled through the Clinton County Health Department.
Does the City of Wilmington issue permits for construction of mobile/manufactured homes?
Mobile/manufactured homes must go through a third party for permitting and inspections. Please contact the Ohio Manufactured Homes Commission Website at www.omhc.ohio.gov or by phone at (614)734-8454 for more information. If you are planning on constructing a mobile/manufactured home within the City limits, you will need to contact our office for zoning approval.
What building codes do you enforce?
Residential building is enforced under the 2013 Residential Code of Ohio. Commercial building work is enforced under the 2011 Ohio Building Code. Electrical work is under the 2011 National Electrical Code.
Where can I see a copy of the code?
Code books are available for viewing in our office, as well as the Clinton County Law Library and the Public Library. In addition, several of the local building supply businesses have the code books available at the contractor's desk.
What is zoning?
Zoning refers to legislation that basically maintains the integrity of the neighborhood, whether residential or commercial. An extreme example of the benefits of zoning would be as follows: Zoning legislation would stop your neighbor from operating a landfill next to your home located in a nice quiet subdivision. By maintaining the integrity of the neighborhood, zoning protects your property value and enables you to enjoy your home, without excessive noise from traffic or industry right next door.
Do I need a zoning permit?
No. There is not a separate zoning permit. Building permits are reviewed for zoning as well as building codes. If you are planning to build a mobile/manufactured home, however, you will need to apply for zoning and site approval through our Building Department.
