How Hernando Handles Accessory Structures: A Practical Guide

Hernando maintains 32 local ordinances across all categories, and 3 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Hernando falls on the strict-to-permissive spectrum compared to other cities.

ADU Rules

Hernando, Mississippi regulates accessory uses through Article XII (Accessory Buildings and Uses) of its Zoning Ordinance, codified as Appendix B of the Code of Ordinances. The ordinance defines an accessory building as a subordinate building incidental and customary to the principal building or use on the same lot, and Mississippi has no statewide ADU mandate, leaving authority to municipalities under Miss. Code Ann. Title 17 (Local Government). Building permits for accessory structures are issued by the Office of Planning / Building Department.

Key details: Governing Document: Zoning Ord. App. B, Art. XII. Adoption Date: Effective July 17, 2007. State ADU Statute: None (Miss. Code Ann. Title 17). Building Code: 2024 IBC adopted by City. Permits: Building Department / mgoconnect.org.

Constructing an accessory building or interior conversion that creates a separate dwelling unit without zoning approval and a building permit is a violation of Appendix B (Zoning) and the adopted building codes. Enforcement is through the Office of Planning and Building Department; remedies include stop-work orders, required removal or modification, and civil fines. Continued occupancy of an unpermitted dwelling can trigger additional building official action.

This is one of the stricter rules in Hernando's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Garage Conversions

Garage conversion in Hernando, MS needs a building permit and zoning review from the Office of Planning. Work must meet the 2024 IBC adopted by Hernando and Zoning Ordinance Article XII. Loss of off-street parking and creating a second dwelling are common denial reasons.

Key details: Required Permits: Building permit + zoning review. Building Code: 2024 IBC/IRC + 2023 NEC. Zoning Reference: Hernando Zoning Ord. Art. XII. Accessory Bldg Setback: 5 ft from side and rear lot lines. Second Dwelling in SF Zones: Generally not allowed by right.

Converting a garage without a building permit and zoning review, or creating an unpermitted second dwelling unit, violates the Hernando Zoning Ordinance and adopted Building Code and can trigger stop-work orders, fines, and denial of future Certificates of Occupancy.

Shed Rules

Hernando 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.

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

The Bottom Line

Hernando'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 Hernando is broadly strict or permissive.

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