Ocean Springs's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Ocean Springs, Mississippi, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Shed Rules

Ocean Springs regulates sheds and outbuildings through local building and zoning codes. Small sheds under 120 to 200 square feet may be exempt from permit requirements in many municipalities.

Key details: Permit Exempt: Under 120 to 200 sq ft. Setback: 3 to 5 ft from property line. Habitation: Prohibited. Flood Zone: Additional rules apply.

Unpermitted structure: $100 to $300 fine. Structures violating setbacks may require relocation or removal. Habitation of sheds results in immediate enforcement action.

Ocean Springs is more permissive than most cities when it comes to shed rules. That said, there are still limits.

ADU Rules

The Ocean Springs Unified Development Code Section 6.3 permits one internal, attached, or detached accessory dwelling unit (ADU) in association with any single-family dwelling. Section 6.3 covers detached ADU specifications, scale requirements, building design standards, occupancy rules, parking, and utilities. ADUs are authorized through the city's local zoning power under Miss. Code Ann. § 17-1-9 (municipal zoning enabling act). Permits are issued by the Ocean Springs Building Department at 1014 Porter Avenue (228-875-6712).

Key details: Code Section: Ocean Springs UDC § 6.3. Allowed Types: Internal, attached, or detached. ADUs Per Lot: One per single-family dwelling. State Authority: Miss. Code Ann. § 17-1-9. Building Code: 2018 IRC (adopted Aug. 21, 2018).

Building an ADU without a permit violates Ocean Springs' Unified Development Code and the adopted 2018 IRC. Unpermitted construction can be required to come into compliance through after-the-fact permitting, modification, or removal. Ocean Springs code enforcement may issue stop-work orders and citations.

Garage Conversions

Ocean Springs' Unified Development Code permits one internal, attached, or detached accessory dwelling unit per single-family lot, which is the typical pathway for legal garage conversions. A building permit and zoning compliance review are required, plus coastal wind-load engineering for Jackson County.

Key details: Code Source: Unified Development Code (Appendix C/D). ADUs Per Lot: 1 (internal, attached, or detached). Building Code: MS-adopted IRC/IBC. Wind Design: ASCE 7 coastal Jackson County. Flood Zone: FEMA elevation rules in AE/VE.

Occupying converted space without a permit, failing required wind or flood elevation standards, or exceeding the one-ADU-per-lot limit can result in stop-work orders, permit revocation, and required removal of unpermitted construction. Confirm fine amounts with Community Development at 228-875-4415.

The Bottom Line

Ocean Springs's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Ocean Springs is broadly strict or permissive.

These rules come from Ocean Springs's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
