Home Additions in Colesville, MD

The addition packet follows the 2021 International Energy Conservation Code as amended by Montgomery County Executive Regulation 13-24. An addition that does not increase conditioned floor area by more than 70 square feet is exempt from the building thermal-envelope rules of Section R402, except the glazing rules, when the building with the addition does not use more energy than the existing building.

With the energy selection form, the Colesville plans mark the thermal envelope, show insulation R-values or U-factors and where the insulation goes, and show each window and door U-factor from Table R402.1.2. The mechanical system design criteria form is prepared by a mechanical contractor. Real Elite coordinates that trade for the Colesville addition and does not do the HVAC work.

The submittal includes a Maryland Department of Assessments and Taxation Real Property Data Search printout that shows the land area. When the Colesville house is in a historic location, the packet includes stamped plans and a letter of conditions from the Historic Preservation Commission. Work that disturbs 5,000 square feet, or that moves 100 cubic yards of earth, needs a sediment-control permit. A Colesville revision can be filed only before final inspection. Changes are dated and clouded, and the revision uses the same permit number in the Department of Permitting Services online service.
