Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

Project questions
Union County Planning and Zoning is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
No verified online portal was located in the reviewed public materials. Contact 605-356-3354 and request the current application route before preparing a final submittal.
A typical review timeline was not verified. Ask the agency for its current completeness and review estimate.
Call Union County Planning and Zoning at 605-356-3354 to coordinate any required inspection. The Planning Director or an authorized representative may inspect at reasonable times to enforce the ordinance or investigate a suspected violation, following lawful entry procedures. No online inspection scheduler or published staged structural-inspection sequence was found; state trade inspections are separate.
Union County administers its 2008 Revised Zoning Regulations, as subsequently amended, within the county's unincorporated territory. No separate county-adopted structural model-code edition was verified. For covered new nonresidential work begun after July 1, 2026 where no local structural code applies, South Dakota's statutory design baseline is the 2024 International Building Code, subject to exclusions for residential structures, manufactured/mobile homes, farmsteads, and accessory farm buildings. State electrical, plumbing, and other trade requirements remain separate. The county ordinance broadly requires a separate building permit to erect, construct, change, enlarge, alter, repair, move, improve, remove, convert, demolish, use, occupy, or maintain each regulated building, structure, or land-use change; it publishes no general cosmetic-work exemption list. The Planning Director may waive the site-plan submission when plan review is unnecessary, but this is not a permit exemption. South Dakota law prohibits requiring a permit for an owner-occupied detached single-family home's same-size repair or substantially similar replacement of a door, downspout, fascia, fence panel or post, gutter, nonstructural siding, soffit, or window, except for designated historic property.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
