Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
2021 International Building Code and 2021 International Residential Code, adopted by Brookings County Ordinance 2026-01. The county booklet states these codes regulate new residences, residential additions and garages, agricultural-structure snow loads, and mobile/manufactured-home tie-downs. Electrical work must comply with the National Electrical Code and receive state inspection.
Inspection lane
Call the Brookings County Zoning Office at 605-696-8350 at least 24 hours before every required inspection. Typical residential inspections are foundation or slab before concealment/backfill, framing/plumbing/insulation before sheetrock, and final after completion; garages and agricultural snow loads are inspected at completion, and mobile/manufactured-home tie-downs within 30 days of placement. State inspectors handle electrical work.
Minor-work playbook
No county building permit is required for buildings under 120 square feet such as playhouses, tool sheds, and yard-storage buildings; minor repairs such as residing, shingling, and painting when remodeling does not increase structure size; semi-portable agricultural structures such as feed bunks, water tanks, temporary grain storage, and calf shelters; fences, trees, shrubs, and retaining walls, although shelterbelts must meet setbacks; or private wells, stock dams, irrigation facilities, rural-water service lines, and compliant household septic systems.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Call the Brookings County Zoning Office at 605-696-8350 at least 24 hours before every required inspection. Typical residential inspections are foundation or slab before concealment/backfill, framing/plumbing/insulation before sheetrock, and final after completion; garages and agricultural snow loads are inspected at completion, and mobile/manufactured-home tie-downs within 30 days of placement. State inspectors handle electrical work.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
