Do You Need I'On Design Committee Approval to Renovate?

For exterior and landscape changes, yes. I'On's design review is run by the I'On Design Committee (IDC) of the I'On Assembly, the neighborhood's homeowners association, under its Architectural & Landscape Guidelines. The Town of Mount Pleasant issues the building permit separately.

Quick answer

In I'On, exterior and landscape changes go to the I'On Design Committee (IDC) of the I'On Assembly before work starts. The IDC publishes its Architectural & Landscape Guidelines, its application review process, its application deadlines and meeting dates, and its applications and checklists on ioncommunity.com. This is private covenant review, separate from the Town. The building permit comes from the Town of Mount Pleasant through its online permitting system.

Who approves exterior changes in I'On?

The I'On Design Committee applies the community's Architectural & Landscape Guidelines. I'On was planned as a traditional neighborhood, with porches close to the street, a strong street wall and consistent materials, so the guidelines care about how a change reads from the street as much as about the change itself.

The IDC is not a Town board. Its authority comes from the covenants recorded against I'On lots. That is why its process, deadlines and fees come from the Assembly, not from Town Hall.

Where are the deadlines and forms?

The IDC section of the I'On community site has four parts. Read them in this order:

Deadlines and meeting dates change each year, so take them from the current schedule on the I'On site, not from a third-party page, including this one.

Step by step

  1. Read the Architectural & Landscape Guidelines for the change you have in mind.
  2. Pick the application and checklist that match the project.
  3. Take the deadline from the IDC's current deadline and meeting-date schedule.
  4. Submit a complete package: drawings, materials and anything else the checklist asks for.
  5. After IDC approval, apply for the Town of Mount Pleasant building permit through the Town's online permitting system. Licensed trade subcontractors pull their own permits.

Does an interior remodel in I'On need IDC approval?

The IDC's remit is architectural and landscape: what you see from outside. A kitchen or bath that stays inside the walls is normally a Town permit question only. It needs a permit if plumbing, electrical or structure changes. If the work changes a window, adds a roof vent or moves a condenser, check the IDC guidelines first.
