Solar Permit in Indianapolis, Indiana
Permit required
Yes, a permit is required
Before installing a residential rooftop or ground-mounted solar photovoltaic system, and before energizing it, since an interconnection agreement with AES Indiana is a listed requirement.

Quick answer
The city's own residential solar requirements checklist lists electrical, structural and improvement location permits from DBNS, plus drainage, as the permits and approvals needed for a residential solar photovoltaic system, with no size exemption published. The checklist also requires that construction documents be reviewed or designed and, if needed, sealed by a professional engineer registered in Indiana, that the applicant hold an appropriate electrical system interconnection agreement with AES Indiana, and that the applicant verify compliance with zoning, planned development, historic and conservation district rules. The zoning ordinance limits where panels may go: accessory renewable energy facilities for solar shall only be located in side and rear yards or on rooftops, and rooftop solar may exceed the maximum height requirement by a maximum of 18 inches. Panels placed in a floodplain also need a permit from the Indiana DNR Division of Water.

What a solar permit costs in Indianapolis
How to apply in Indianapolis
A rooftop solar PV permit application is a combined structural and electrical plan set: a site plan and roof framing details proving the array's mounting can carry its added loads, plus a one line electrical diagram covering listed modules and inverters, disconnects, and the rapid shutdown design. Utility interconnection is a separate approval that runs in parallel with the permit.
What most solar permit applications include:
- Both a building permit and a separate electrical permit are required, since the array must be designed and installed to the residential code's solar provisions and to the National Electrical Code (IRC R324.3).
- The plan set identifies listed equipment: PV modules listed to UL 1703 (or both UL 61730-1 and UL 61730-2), and inverters listed to UL 1741, with grid-tied inverters listed for utility interaction (IRC R324.3.1).
- Structural drawings show that the roof framing is designed to structurally support the array and withstand the gravity loads it adds (IRC R324.4.1).
- The site plan lays out roof access pathways at least 36 inches wide, plus a ridge setback sized to how much of the roof the array covers, so firefighters retain pathways and ventilation access (IRC R324.6.1, IRC R324.6.2).
- The one line electrical diagram shows the rapid shutdown method and the location of its single initiation device, since one control point must bring all system conductors down to safe levels (NEC 690.12, NEC 690.56(C)).
- Interconnecting the array to the utility grid at a defined point of connection is a separate application process from the local building or electrical permit and must be approved before the system can operate (NEC 705.12).
- Some permitting offices route applications through SolarAPP+, an automated review platform that checks the plan set against code requirements and issues eligible permits instantly (DOE SolarAPP+).

Inspections and closing out your permit
Inspectors verify the installed array against the approved plans, and some agencies run a rough check of roof attachments and penetrations while they are still exposed before the wiring and roofing close them in. The final inspection confirms rapid shutdown, disconnects, grounding, and required labels are installed correctly, and the system cannot be energized until the utility separately approves interconnection.
- Where an agency runs a rough or pre-inspection, it checks the array's roof penetrations while they are still exposed, confirming they are flashed and sealed (IRC R324.4.3).
- The inspector confirms whether rapid shutdown is required, how it is accomplished, and that it is properly identified (NEC 690.12, NEC 690.56(C)).
- PV disconnecting means must be permanently marked and installed where they are readily accessible, which the inspector confirms in the field (NEC 690.13).
- Bonding and grounding of the array, including every exposed non current carrying metal part and the grounding electrode system, is checked before sign off (NEC 690.43, NEC 690.47).
- At the service equipment, the inspector looks for the required rapid shutdown placard, a labeled diagram showing the initiation device's location in the specified colors and letter sizes (NEC 690.56(C)).
- Utility interconnection is inspected and approved separately from the local building department's sign off, and the system cannot be energized until both approvals are in hand (NEC 705.12).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Indianapolis permit portal or by phone at 317.327.8700.

- How long does a solar permit take in Indianapolis?
- DBNS target for initial review is 10 business days for remodels, additions and similar residential projects. Times can vary by workload and project scope, so confirm with the office.
- Where do you apply for a solar permit in Indianapolis?
- You can apply through the Indianapolis permit portal or contact the City of Indianapolis Department of Business and Neighborhood Services (DBNS) directly. The links are listed on this page.
- Can a homeowner pull a solar permit themselves in Indianapolis?
- Under Indiana law (IC 36-7-8-3(a); IC 36-7-8-3(d); IC 25-28.5-1-11; IC 25-28.5-1-32(5)): Indiana is unusually permissive toward the homeowner doing the work. IC 36-7-8-3(d) provides that a county building standards ordinance adopted under that section does not apply to private homes that are built by individuals and used for their own occupancy, although the onsite sewage system still must comply with state law. That exemption is narrow: it reaches county ordinances for unincorporated areas under IC 36-7-8, not a city or town permit ordinance, so a homeowner inside municipal limits still answers to the local building department. On the trades, Indiana licenses plumbers at the state level but exempts the homeowner: IC 25-28.5-1-11 makes it unlawful to act as a plumbing contractor or journeyman plumber without a state license, while IC 25-28.5-1-32(5) excludes the owner occupant of a dwelling of eight or fewer residential units who is installing, altering, or repairing the plumbing system. Electricians are not licensed by the state at all: Indiana Code Title 25, which houses the professions and occupations licensing chapters, contains no electrician licensing chapter, and IC 36-7-8-3(a) instead lets a county adopt electrical standards by ordinance, so electrical licensing in Indiana is a local matter. Confirm how Indianapolis applies this before you apply.
