Construction Plan Requirements

As part of the Building Permit Application ,a detailed construction plan must be submitted to the Building Inspector before the Building Permit can be issued. The reason for this procedure is to assure that the project you are planning will meet the current State of Connecticut Building Code. If you were to build a project without proper plan review, your project may be rejected and this would surely cost extra time and money.

Following is a list of items that should be included on the building plan:
  • Draw the plan neatly and to scale (1/4" per foot etc.)
  • Show a plan view or overhead showing size of building with doors and window openings. Label each room as to the use of that room.
  • Show a cross section or a side view of the foundation type that will be used in this project.
  • Show a cross section or elevation of any wall section showing floor joist, studs, wall plates, ceiling joists rafters and roofing materials.
  • Show a detail of any guardrails and handrail systems at landings, decks and stairways.
  • Any bedroom addition must show an egress size window in each of the bedrooms.
