Common questions about Dakota County permits, shoreland and floodplain rules, deck exemptions, contractor licensing, and unpermitted work consequences.
How do I know if my property is in a Dakota County shoreland or floodplain area?
Use the Dakota County GIS Property Search tool (linked in the sidebar) to check your property. If your land is within 1,000 feet of a public water body or in a FEMA-designated floodplain, you'll need an additional permit from Dakota County Water Resources before starting work. Call (952) 891-7000 if you're unsure — it's worth checking before you apply to your city, not after.
When does a deck require a building permit in Dakota County?
Decks over 200 sq ft require a building permit across most Dakota County cities. Ground-level decks not attached to the house and under 30 inches high are typically exempt — but must still meet zoning setbacks. Any deck attached to the house or elevated requires a permit regardless of size. Always confirm with your specific city before building.
Does my contractor need to be licensed in Dakota County?
Yes. All contractors doing permitted work must hold a valid Minnesota state license. Mechanical (HVAC), plumbing, and electrical contractors each have specific state licensing requirements. Verify any contractor at the DOLI license lookup before hiring. If they won't pull a permit, walk away.
What happens if I do work without a permit in Dakota County?
Cities can require completed work to be opened or demolished for inspection at your cost. A penalty fee — typically equal to the permit fee — is charged on top. Unpermitted work must be disclosed when selling and can delay or kill a sale. If the work is in a shoreland or floodplain area, the consequences are more serious and may involve county-level enforcement as well.
Determine which city or township your property is located in. Each has its own building department and permit requirements. Use Dakota County property search tools if uncertain.
Prepare site plans, construction drawings, contractor information with state license number, and project specifications. Requirements vary by project type and city.
Most Dakota County cities accept online permit applications. Create an account on your city's permit portal, complete the application, upload required documents, and pay application fees.
After permit approval, schedule required inspections through your city's online portal or by phone. Most cities require 24-hour advance notice. Keep approved plans on-site during all inspections.

Properties within 1,000 feet of public waters or in FEMA floodplains require additional permits from Dakota County Water Resources. Call (952) 891-7000 for determinations.
