Clinton County Building Department 2026: Permits, Inspections & Services

Clinton County, Michigan Building Permits & Inspections: 2026 Guide

If you are building a new home, adding a room, replacing a roof, installing electrical or plumbing work, putting in a deck, or planning another construction project in Clinton County, the first question is not simply “Do I need a permit?” You also need to make sure Clinton County is actually the office responsible for your property.

Clinton County’s current Building Department page says permit applications, plans and supporting documents can be submitted by email, in person or by mail, with email generally being the most efficient method. During busy periods, the county warns applicants to allow roughly 10–14 business days for review.

This page is for Clinton County, Michigan. Clinton County also exists in other states, including Ohio, Indiana and New York. Do not use the Michigan contact details below if your project is outside Clinton County, Michigan.

First Check: Does Clinton County Issue the Permit for Your Property?

This is one of the easiest places to make a costly mistake. A Clinton County mailing address does not automatically mean the county Building Department controls every building permit.

The county’s published jurisdiction list identifies building jurisdiction for the following 13 townships, two cities and six villages:

The same county jurisdiction document lists these locations as not covered by the Clinton County Building Department for ordinary building jurisdiction:

• Bath Charter Township
• City of DeWitt
• City of East Lansing
• City of Grand Ledge
• City of Lansing
• DeWitt Charter Township
• Watertown Charter Township
• Village of Bath

Before preparing plans, use the county’s official jurisdiction information or call 989-224-5181 with the property address and parcel information.

What Services Does the Clinton County Building Department Handle?

Do You Need a Building Permit?

Michigan requires a building permit before many construction, alteration, addition, demolition and occupancy-change projects begin. Clinton County’s own FAQ says a permit is generally required when construction physically alters or adds to a structure or when the work is regulated by applicable codes or ordinances.

Ordinary minor repairs may not require a building permit, but the exemption does not extend to work that affects structural supports, required exits, regulated wiring, plumbing, mechanical systems or other safety-related systems.

How to Apply for a Clinton County Building Permit

1. Confirm the permitting jurisdiction.
   Use the property address and parcel information to make sure Clinton County is the correct enforcing agency. If you are in Bath Charter Township, DeWitt Charter Township, Watertown Charter Township or another separately administered city, contact that jurisdiction before submitting county building forms.
2. Check zoning or land-use approval first.
   Many new structures, additions, decks and accessory buildings need zoning review before the building permit can be completed. The county Forms Center includes a zoning/land-use form and jurisdiction guidance.
3. Choose the correct application and project checklist.
   Open the Clinton County Forms Center. Select the residential building, commercial building, electrical, mechanical, plumbing, demolition, SESC or other form that matches your work. For homes, the county also publishes dedicated packets for new houses, decks, pools and accessory structures.
4. Prepare the plans and supporting documents.
   A residential building application asks for the project address, parcel ID, township, owner information, project type, project valuation, dimensions and contractor information. The county requires a plan copy and tells applicants to follow the checklist for the particular project.
5. Submit the complete packet.
   The current county page allows applications, plans and supporting documents to be sent by email, delivered in person or mailed. The county says email is generally the most efficient option. Send permit materials to permits@clinton-county.org unless the particular form instructs otherwise.
6. Allow time for review and respond to corrections.
   The current Building Department page warns applicants that review can take approximately 10–14 business days during busy building season. An older county FAQ mentions 3–5 business days, so 10–14 business days is the safer planning assumption in 2026. Incomplete or unclear plans may be returned or held until missing details are supplied.
7. Receive the permit before starting regulated work.
   Do not treat application submission as approval. Wait until the permit has actually been issued, follow the approved plans, post the permit as required and request inspections before covered work is concealed.

Documents to Prepare Before You Apply

The exact packet depends on the project, but preparing these items before submission can prevent avoidable delays:

• Property address and parcel ID.
• Property owner’s name and contact information.
• Township, city or village jurisdiction.
• Clear description of the proposed work.
• Project valuation where requested.
• Site or plot plan showing the project location.
• Floor plans with dimensions for applicable building work.
• Foundation plan where applicable.
• Building cross sections and structural details.
• Braced-wall information when required.
• Truss specifications when applicable.
• Contractor business and license information.
• Zoning or local land-use approval when required.
• SESC application or waiver information if the project disturbs soil.
• Any septic, well, driveway, utility or other outside approvals required for the specific site.

For a simple project such as a replacement roof, the documentation may be much lighter. A new home or major addition can involve several approvals and separate trade permits.

Can You Apply Online?

Yes, but not every permit follows the same online path.

Clinton County uses BS&A Online for participating permit services, record searches and payments.

The county specifically states that online building permits are available for:

• Roofing
• Siding
• Windows/doors involving three or more

The county also provides online application links for plumbing, mechanical and electrical permits.

Clinton County Building Permit Fees in 2026

There is no single flat fee for every construction permit. The county’s building FAQ says building permit charges are based on project valuation using ICC Building Valuation Data. For an exact building-permit estimate, contact the department with the project scope and valuation information.

Fees can change and complicated projects can have several permits. Treat the amounts above as published county charges, not a final project quote.

How to Schedule a Clinton County Building Inspection

The county’s current instruction is straightforward:

• Call 989-224-5183.
• Give at least 24 hours’ notice.
• Leave the request before 4:00 p.m. on the business day before you need the inspection.
• Use the dedicated inspection line for scheduling.

The county lists these general inspection days:

Have This Information Ready When You Call

The county’s permit-holder instructions ask callers to be ready with:

1. Permit number.
2. Complete inspection-site address.
3. Homeowner and contractor name.
4. Type of construction, such as new home, addition or commercial project.
5. Type of inspection requested.
6. Whether the building is open or how the inspector will gain authorized access.
7. A phone number where you can be reached.

The permit should be posted where required and the inspection location must be identifiable. If the work is not ready or the inspector cannot access the building, a reinspection charge can result.

Typical Inspection Sequence

Building Inspections

• Footing: After forms or trenches are ready but before concrete is poured.
• Foundation wall: After required reinforcement and forms are ready, before concrete where applicable.
• Backfill: After required waterproofing/damp-proofing and drainage preparation, before concealment.
• Rough frame: After framing and related structural work is installed but before insulation or drywall. Required rough electrical, plumbing and mechanical inspections should be completed first where applicable.
• Insulation: Before insulation is concealed.
• Final: After the project is complete and required trade finals have been approved.

Electrical Inspections

• Temporary or permanent electrical service when ready for connection.
• Rough electrical before insulation or drywall covers the work.
• Final inspection after fixtures, devices and required covers are installed and the electrical work is complete.

Mechanical Inspections

• Underground work before it is covered by dirt or concrete.
• Rough mechanical before systems are concealed.
• Final inspection when equipment and required systems are complete and operating.

Plumbing Inspections

• Underground water and drain lines before fill or concrete covers them.
• Rough plumbing before insulation or wall coverings conceal piping.
• Final inspection after fixtures and systems are complete and operating.

Soil Erosion and Sedimentation Control (SESC)

Clinton County’s SESC program is especially important for new homes, additions, grading and other projects that disturb land.

According to the county’s SESC guide, a permit is generally required when:

• An earth change occurs within 500 feet of a lake, stream or wetland.
• An earth change occurs within 100 feet of a county drain.
• The project disturbs one acre or more.
• Certain removal of clay, gravel, sand, peat or topsoil meets the ordinance conditions.

A project disturbing less than 225 square feet may qualify for a waiver in certain situations when it is close to a lake, stream or county/municipal drain. Some minor earth changes that are stabilized within 24 hours may qualify for an exemption.

Because the exact facts matter, submit the project information and allow the county to determine whether a permit, waiver or exemption applies.

Use the official Clinton County SESC page for the ordinance, user guide, forms and current fee information.

For active SESC sites, common practical responsibilities include protecting storm inlets, maintaining silt fencing, controlling mud and sediment tracked onto roads, stabilizing disturbed land and preserving vegetation where possible.

Michigan Building Codes Used in 2026

Clinton County administers permits under Michigan’s state construction-code system. As of October 2026, Michigan LARA lists these primary current code editions:

For current statewide editions, amendments and rule changes, check the Michigan Bureau of Construction Codes code-book page.

Code adoption can change during a long project. If your drawings depend on a particular code provision, confirm the applicable edition for the permit application date before finalizing the design.

Can a Homeowner Pull Their Own Permit?

Michigan allows qualifying homeowners to perform certain work on a single-family home they own and occupy or are about to occupy, subject to the applicable law and permit requirements.

For example, the county electrical, mechanical and plumbing forms include homeowner affidavits. Those affidavits are not a way to obtain a homeowner permit so an unlicensed third party can perform work that legally requires a licensed contractor.

If a licensed contractor is performing the work, make sure the contractor obtains or is properly associated with the required permit and is registered with Clinton County when county registration is required.

How Long Is a Building Permit Active?

The county’s published building FAQ states that construction should begin within 180 days after permit issuance and that work should not stop for more than 180 days, otherwise the permit can expire.

If your project has been delayed, do not simply restart construction. Contact the Building Department with the permit number and ask whether the permit remains active or whether an extension, renewal or new permit is needed.

Check an Existing Permit or Building Record

Clinton County participates in BS&A Online, which provides building-department record search functions.

1. Open Clinton County BS&A Online.
2. Choose the Building Department record search.
3. Search using the available address, parcel number, owner name or building record number.
4. Review the displayed permit and record information.
5. If the record is unclear, old or missing, contact the county directly before assuming no permit exists.

Online data can be useful when buying a property, checking open permits or confirming previous construction, but the county remains the source for an official interpretation of a record.
