A shed with new wiring and a fence-only job do not follow the same application choice in Jackson’s public permit portal. Before buying a structure or arranging delivery, describe its use, placement, support and utility work to the City. A product advertised as “portable” does not answer those questions.
The City’s residential overview names garages, decks and sheds among accessory projects and says requirements depend on scope and complexity. Its Building Permits page also lists portable storage buildings. Neither current page supplies a general size-based exemption.
Which portal description fits the work?
The official application page distinguishes the following situations. This is LSL’s comparison of the public descriptions—not a determination that a particular property qualifies.
| Proposed work | What the Jackson portal says | Question to resolve before applying |
|---|---|---|
| An accessory project associated with a one- or two-family residence | The residential building application covers new construction, renovations, alterations and additions; the City’s separate overview includes accessory structures | Does this structure and use belong in the residential application, and what site/construction documents are needed? |
| Electrical, gas, mechanical or plumbing work as part of a larger building project | Related trades are requested within the larger residential or commercial application by the lead applicant | Which trades and contractors must be included in that application? |
| Only electrical, gas, mechanical or plumbing work, not associated with a residential or commercial building permit | Each trade has a standalone application choice | Is this genuinely standalone work, or part of an existing building project? |
| A fence-only project | The fence description says to use the fence application, not the residential building application | Does the proposal include a gate, alteration or enclosure that needs to be described with the fence? |
| An onsite portable storage container or POD | The portal provides a separate POD application | Is the proposed item a POD, another accessory structure or a different use? |
The trade distinction concerns where to apply. It does not eliminate trade review or inspections, and it does not mean every shed needs every trade. Describe what will actually be installed. Do not create several standalone applications solely because an older checklist gave each trade its own row.
Send a project description, not just a product name
Use this short LSL prompt when asking the City to classify the proposal:
At [address/parcel], I propose [use and structure], measuring [exterior dimensions], supported by [foundation/anchoring details], located [position shown on a site sketch]. It will [attach to an existing building or remain separate] and include [actual electrical, gas, plumbing or mechanical work]. Which application and documents should cover this complete scope?
These are useful screening details, not a substitute for the City’s application or a promise that a sketch is sufficient. Confirm City jurisdiction first; a Jackson mailing address alone is not the answer.
Two hypothetical rectangular footprints illustrate the measurement, not permit eligibility: 8 × 10 feet = 80 square feet and 10 × 12 feet = 120 square feet. Neither calculation establishes a foundation, setback, use, structural design or utility requirement. Have the City resolve those questions before treating a vendor’s dimensions as clearance to place the structure.
If the plan changes—from storage to an occupied workspace, for example—send the changed use and systems back to the office. The earlier answer addressed the earlier scope.
Why the former size test is no longer here
Our earlier guide cited a City FAQ about 108 square feet and permanent foundations. That URL returned 404 during the September 12 review. The accessible current City pages and portal do not reproduce a numeric test. We have therefore withdrawn that advice, not concluded that Jackson changed its rule.
The overlapping article, “Jackson’s accessory-building test includes size and foundation,” has been consolidated here. It also incorrectly treated exactly 108 square feet as covered by wording that only described greater-than and less-than cases. Readers should ask permit staff for the current applicable rule rather than rely on either former interpretation.
The public portal lists 601-960-1160 for permit assistance. Once the correct application is identified, see our separate Jackson application-review and issuance guide for the City’s physical-plan instruction, review dependencies and inspection route.
What LSL checked
On September 12, 2026, we read the two current City pages and the publicly rendered OpenGov application descriptions linked by the City. We compared application scope, retained two illustrative footprint calculations and removed unsupported FAQ-based classifications. We did not submit a project, consult staff, inspect a property or test a logged-in workflow. Recheck the linked descriptions when ready to apply.
