El Portal Administrative Site Ketron/Greenleaf Addition
The owners of a private home in the El Portal Administrative Site would like to add to their residence. The house is located within a residential neighborhood administered by the National Park Service (NPS) to provide housing for employees, contractors, and park partners.
The homeowners would like to build a one bedroom, one bathroom studio as an addition to their existing residence. In order to obtain a Mariposa County building permit to construct this addition they must first obtain the approval of the NPS.
The footprint for the addition will encompass the existing studio unit and total 20' x 32'. The new addition will include an accessory room, bedroom, bathroom, external stairs and new decks. The majority of the work will be done by the homeowner.
There will be ground disturbance during the construction of the addition's 12' x 20' concrete slab foundation, plus pier supports for stairs and the deck, and new utilities lines. The new studio, as well as a portion of the current residence, will be sided with a green hardibacker siding to match all new construction with the original home. The roof will be metal of a light color.
