For a Jackson shed, garage, deck, or similar project, square feet are one field—not the permit answer. The City’s storage-building FAQ adds foundation to its size wording, while its broader residential guidance names several accessory structures and separates building, zoning, trade, inspection, and final records.
Start with the actual structure and complete scope. Then ask City permit staff to classify that record in writing before work.
Use this nine-field scope card
| Field | What to record | Why it stays separate |
|---|---|---|
| 1. Authority | Address, boundary source, and City-office confirmation | A Jackson mailing address can be outside City limits |
| 2. Structure/use | Shed, storage building, garage, deck, fence, pool, shelter, or other use | One category’s wording may not control another |
| 3. Footprint | Exterior length, width, and calculated square feet | Size alone does not decide foundation, zoning, or trades |
| 4. Foundation | Slab, footing, piers, anchors, skids, or other support as designed | The City FAQ expressly uses foundation in its storage-building distinction |
| 5. Structural scope | Framing, loads, attachment, openings, roof, and site work | A “portable” label may omit actual work |
| 6. Trades | Electrical, plumbing, fuel gas, mechanical, or other systems | Trade permits are separate records |
| 7. Site/zoning | Plot, setbacks, easements, drainage/flood facts, and zoning response | Building and placement questions differ |
| 8. Permit decisions | Applications, written classifications, issued permits, plans, and conditions | A question or receipt is not issuance |
| 9. Completion | Inspection requests/results, accepted corrections, and final City approval | Work appearing finished is not final approval |
The current Residential Buildings and Permits page names garages, decks, and sheds among accessory structures and says requirements vary by scope and complexity. It also says applications are reviewed for building-code, zoning, and safety requirements, with inspections at stages and final approval before a project is considered complete.
Keep the 108-square-foot wording narrow
Jackson’s permit FAQ says accessory storage buildings greater than 108 square feet require a building permit. It also says storage buildings below 108 square feet require a permit when they include a permanent foundation.
Two measurement examples show what to put on the card:
- 8 feet × 10 feet = 80 square feet;
- 10 feet × 12 feet = 120 square feet.
Those calculations document a rectangular footprint. They do not classify the project. The 80-square-foot example still needs a foundation, use, site, zoning, structural, and trade record. The 120-square-foot example does not reveal the whole permit package or every related approval.
Do not extend the storage-building wording to a deck, garage, fence, storm shelter, pool, play structure, or another use. The same FAQ separately names storm shelters of any type and in-ground pools. That separation is evidence that project type matters.
Define “portable” and “basic repair” with facts
The broader Building Permits page lists fences, tents, satellite dishes, and portable storage buildings among permit categories. A seller’s “portable” label is therefore not an exemption record.
Record how the structure reaches the site, rests on or attaches to the ground, connects to utilities, handles wind/load forces, and will be used. If a project alters an existing building, describe what is removed and changed.
The FAQ describes basic repairs as nonstructural examples such as carpet, paint, siding, and shingle replacement that do not enlarge or alter the basic structure. Do not rename an addition, opening change, structural repair, new deck, or utility installation “basic repair” to fit that sentence.
Carry every trade as its own permit lane
The FAQ says electrical, plumbing, fuel-gas, and mechanical permits are separate from the building permit. Create one row for each trade in the project:
| Trade | Exact scope | Applicant/contractor | Permit number | Rough result | Final result |
|---|---|---|---|---|---|
| Electrical | |||||
| Plumbing | |||||
| Fuel gas | |||||
| Mechanical |
Leave an unused row marked “City confirmed not applicable” with the date and response. Do not silently remove it from the project record.
Close the file with the City’s result
Match the built structure to the approved site and construction records. Retain each inspection request, result, correction, revised plan, and later approval. A contractor saying an inspector visited is not the result; a passed rough inspection is not a passed final.
Before final payment, preserve the permit’s final status and every separate trade closeout. If use, size, foundation, site, or trade scope changes, reopen the City question rather than carrying the original answer forward.
Source and method
Local Service Ledger reviewed three City of Jackson pages on August 12, 2026. We separated their project categories, narrow storage-building wording, trade permits, inspections, and final approval into nine fields. We did not inspect a property or determine permit requirements.
