Per Montgomery County: An amendment to Montgomery County Code Chapter 8-27 regarding the demolition or removal of buildings will go into effect on Monday, Aug. 21, to ensure that when a residential building is demolished or substantially demolished, a demolition permit will be required. The law also will require any new home rebuilt on that site have a new home building permit. The County’s Department of Permitting Services (DPS) issues the permits.
The amended legislation redefines the term demolition to include removal of two-thirds (67 percent) of first story exterior walls of a single-family or two-family dwelling (duplex or townhouse) or if less than one-third of existing first-floor exterior walls (enclosing a habitable space of a house) are left in place above the basement or foundation.
