Mechanical Plans
  • New dwellings require:

  • For alterations or additions to existing dwellings, the same requirements apply.

This allows the required information to bypass mechanical plan review and be reviewed at a later date by the field inspector at the time of the mechanical inspection.
  • When adding or replacing exterior units, a scaled, certified plat is required. It must clearly indicate the location of the new or replacement unit(s).
  • New houses will show the water service location and pipe size on the site/grading plan.
  • Renovations and additions to existing dwellings may continue to use the existing water service
  • Plumbing riser diagrams are not required, except for unusual features such as solar water heating systems.
  • All projects will show plumbing fixture layouts as part of the architectural plans.
  • Compliance with the IRC for electrical is by field inspection only.
  • The Department of Environmental Services (DES) will need to review any boxes, devices, switches, towers, conduit, etc. that will be installed within the right of way. Plans shall show the riser diagram and a profile of purposed equipment.
