Town of Cornish’s own rules

  • Lot area is in thousands of square feet in Table 2.
  • Rural residential district (rr) is described as requiring larger minimum lot sizes to maintain rural character.

• Mandatory utility hookupConditional

  A new home inside Cornish town limits. Public sewer is available only in the village district; public water is a metered town service.

  sewer availability: village district only

Town of Cornish does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Who permits septicState (with conditions)

  Subsurface sewage disposal on private land inside Cornish town limits where the property is not served by public sewer. The state subsurface wastewater rules govern; the Cornish plumbing inspector and code enforcement officer administer the local permit step.

  • Municipal sewer exists only in the village district per the town page.

  “The Local Plumbing Inspector (hereafter, LPI) shall enforce all the provisions of this rule as a sworn agent of the municipal jurisdiction.”
