Local installation conditions
Marion County permits electrical work through the City of Indianapolis Department of Business and Neighborhood Services, and most participating installers pull that permit as part of the job rather than asking the homeowner to handle it. If your home is in a historic district such as Lockerbie Square, Herron-Morton, or Old Northside, exterior conduit routing may need extra thought, which is exactly the kind of thing a photo answers in seconds.
Housing stock in Indianapolis
Older near-downtown neighborhoods frequently have detached garages served by a small subpanel or, in some cases, no dedicated circuit at all. That can mean a trench or an overhead run, which is the most common reason two Indianapolis quotes for 'the same' charger come back hundreds of dollars apart.

Utility and permitting
Most of Indianapolis is served by AES Indiana, which offers time-of-day residential rate options that reward overnight charging. Ask your installer whether a separately metered or load-managed setup makes sense for your household before the work is scheduled.
