Shed Permit in Indianapolis, IN
Permit Summary
Do You Need a Shed Permit?
Exemptions
For a Class 2 residential structure, a building permit is not required when the structure spans 200 square feet or less of base area, is one story, is not placed on or attached to a permanent foundation, and contains no electrical power distribution system, heating system, space-heating equipment, cooling system, or space-cooling equipment. Separately, an Improvement Location Permit is not required for a mini-barn or shed of 200 square feet or less that is not on a permanent foundation, although all applicable zoning rules still apply. The Class 1 building-permit exemption has different conditions, including a height under 15 feet.
Attached Shed Rules
DBNS's residential submittal checklist treats additions separately from new accessory structures. An attached storage addition should therefore be reviewed under the applicable addition/alteration requirements rather than assumed to qualify for the freestanding accessory-structure path. In all cases, the Class 2 small-structure exemption is unavailable when the structure is placed on or attached to a permanent foundation.
Shed Use Rules
In dwelling districts, sheds are treated as minor residential structures/accessory structures. Accessory uses must be customarily incidental and subordinate to the primary use, under the same ownership and on the same lot, and may not precede the primary building. The Indiana Residential Code applies additional requirements when an accessory structure contains habitable rooms, so converting a storage shed to habitable or dwelling space is not covered by the simple storage-shed rules.
Zoning & Placement Rules
Zoning Rules
An Improvement Location Permit is generally required before locating, erecting, altering, or repairing a structure unless an exemption applies. A mini-barn or shed of 200 square feet or less that is not on a permanent foundation is exempt from the Improvement Location Permit, but all applicable zoning standards still apply. In dwelling districts, an accessory use must be incidental and subordinate to the primary use, under the same ownership and on the same lot, and the accessory structure may not be established before the primary building.
Setback Rules
Setbacks depend on the zoning district and site. For minor residential structures on lots in D-A, D-S, D-1, D-2, D-3, D-4, D-5, D-5II and qualifying D-8 dwelling districts with single-family detached, single-family attached, or two-family dwellings, the structure must meet the district's minimum front and side setbacks (and the established front setback when greater), remain at least 5 feet from a rear lot line, satisfy side-yard requirements independently of the primary building, and stay out of platted easements. Other dwelling districts and special contexts use their own perimeter-yard and dimensional standards.
Maximum Height Rules
Height is zoning-district-specific. The dwelling-district dimensional tables generally cap accessory buildings at 24 feet in D-A through D-5II and qualifying D-8 residential situations, 25 feet in D-6 through D-10 and multifamily D-8 situations, and 20 feet in D-11. In addition, an accessory building or minor residential structure generally must be lower than the primary building. Agricultural-use buildings in qualifying D-A situations have a separate height exception.
Lot Coverage Rules
In dwelling districts, the combined horizontal area of the primary building, accessory buildings, game courts, and minor residential structures must preserve the minimum open space required by the zoning district. The footprint of any one accessory building or minor residential structure must also be smaller than the footprint of the primary building. Commercial and mixed-use districts have different accessory-building area limits, so the applicable zoning district must be checked.
Special Area Rules
Permit exemptions do not waive separate special-area approvals. Exterior work in an Indianapolis Historic Preservation Commission historic district can require a Certificate of Appropriateness, and work in applicable flood-control areas can require a floodplain development permit. DBNS also identifies Regional Center and other site-specific approvals as possible prerequisites when applicable.
Construction Requirements
Foundation Rules
The local Class 2 building-permit exemption is available only when the shed is not placed on or attached to a permanent foundation. Under the currently effective 2020 Indiana Residential Code, Table R309 provides no footing/foundation requirement for portable accessory structures up to 200 square feet; monolithic-footing accessory structures up to 721 square feet use the table's specified footing options, while structures with conventional foundations must comply with the Indiana Residential Code.
Fire Separation Rules
Residential sheds subject to the 2020 Indiana Residential Code must comply with IRC Section R302.1 requirements for exterior walls, projections, openings, and penetrations based on fire-separation distance. Indiana has specific amendments and interpretations for qualifying conditions, so zoning setbacks alone do not establish fire-code compliance.
Permit & Review Path
Permit / Review Path
First determine whether the Class 2 structural exemption applies and, separately, whether the Improvement Location Permit exemption applies. If both apply, no ordinary structural or Improvement Location Permit application is required, but zoning and any special-area rules still govern. Otherwise, a residential applicant submits the applicable Residential Development Application/Improvement Location Permit materials or Class 2 Structural Permit Application with the DBNS checklist and plans through the city's permit system. Class 2 applicants may use city review/inspection or the private-provider path authorized by IC 36-7-2.5. Required prerequisite approvals must be resolved before issuance, and permitted work is subject to applicable inspections and completion documentation.
Trade Permits & Professional Design
Trade Permit Rules
Electrical, plumbing, heating/cooling, and other craft permits may be required when those systems are installed. For Class 2 sheds, installing an electrical power distribution system or heating/cooling equipment also removes eligibility for the small-structure building-permit exemption in Sec. 536-201. Trade work remains subject to the applicable Indianapolis licensing, permit, and inspection rules.
Professional Design Rules
DBNS's residential accessory-structure checklist specifically calls for engineer-sealed truss specifications when applicable. Indianapolis Code Sec. 536-206 also requires architect- or engineer-prepared and sealed plans when state rules require professional design/design release. Whether a design professional is required therefore depends on the structure, framing system, and state-code classification.
What You Need Before Applying
Requirements
Determine whether the project qualifies for both the structural-permit exemption and the separate Improvement Location Permit exemption. All sheds remain subject to applicable zoning even when a permit exemption applies. When a permit is required, submit the applicable DBNS application and plans, obtain any prerequisite zoning or special-area approvals, and comply with the current Indiana building codes and Indianapolis zoning standards.
Required Documents
For a permit-required residential accessory structure, DBNS's current checklist calls for the applicable Residential Development Application when an Improvement Location Permit is required or a Class 2 Structural Permit Application, the Residential Plan Submittal Checklist, a Statement of Intent when the property owner performs the work, and a complete plan set. Accessory-structure plans include floor plans, wall cross-sections from roof to foundation, a foundation plan, and window/door framing details; a site plan and four elevations are required when an Improvement Location Permit applies. Engineer-sealed truss specifications and special-approval documents are required when applicable.
