Review expectation
The ordinance requires the Zoning Officer to grant or deny a routine permit within a reasonable time but gives no fixed number of days. A permit expires if the work is not substantially completed within two years; the officer may extend it when substantial progress has been made. Small-wind-system applications have a specific one-month decision deadline unless reasons for delay are given.

How are inspections scheduled?
Call 605-345-9502 to schedule an appointment with the Zoning Administrator. The officer may inspect buildings or premises as necessary for zoning enforcement and may enter at reasonable times after presenting credentials and requesting entry; no public structural inspection sequence or online scheduler is published.
Which codes and exemptions should I review?
N/A. Day County's permit is a zoning/building-use approval; the adopted 2026 zoning ordinance does not identify a county-adopted structural IBC or IRC edition. It requires applicable state construction and electrical codes for small wind systems and South Dakota onsite-wastewater rules where relevant. A permit is required before erecting, moving, adding to, structurally altering, or using a building or structure, and before excavation or filling, grading, lagooning, or dredging associated with future construction. The adopted ordinance publishes no general size-based shed or cosmetic-work exemption. Limited ordinary repairs to a lawful nonconforming structure may be made without increasing its nonconformity, subject to the ordinance's value and volume limits.
