Permit required

In Ohio, a New Home Construction requires a building permit.

Building a custom home from the ground up requires comprehensive oversight from the city. This involves a master building permit that encompasses zoning, foundation, framing, plumbing, electrical, and HVAC. It is the most heavily regulated residential project, ensuring the dwelling is safe for human habitation.

As one of the more densely populated areas in Ohio, Montgomery County (around 536,096 residents) tends to see higher application volumes at its building department, so it helps to prepare your documentation in advance.

Code Compliance & Inspections

Because of severe winter weather in Ohio, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Ohio Building Code.

Concurrent Permits & HOAs

For Montgomery County residents, we recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Homeowners associations often maintain stricter rules regarding materials and dimensions for your New Home Construction than the county itself.

Zoning & Cost Factors

Ohio utilizes a mix of township and municipal zoning, with state law providing specific exemptions for agricultural activities from local zoning interference. Fortunately, Ohio maintains relatively builder-friendly regulations, keeping base permit fees competitive.
