Additions are considered major alterations and are generally considered to be those, which substantially alter the existing structure and become as an original fixture of the existing house.  Major building alterations include, but are not limited to, construction of driveways, garages, porches, greenhouses (attached and detached), rooms, fireplaces, chimneys, other additions to a home, etc.

When planning an addition, please consider filing your application for that addition as soon as the very first concept plans are drawn.  This will allow the Architectural Review Board to work with you and your designer so your project will head in the right direction, and you will avoid additional costs for changes.

Additions to townhouses are not allowed.

Carports are not permitted.

• The location of major alterations should not impair the view, the amount of sunlight, or the natural ventilation of adjacent properties.  Room additions and garages must meet Loudoun County setback requirements and may not be constructed across Building Restriction Lines (BRL). 

• The design of major alterations should be compatible in scale, materials and color with the house and adjacent homes. Pitched roofs must match the slope of the roof on the house.

• New windows and doors should match the type used in the house and should be located in a manner which will relate well to the location of exterior openings in the existing house. If changes in grade or other conditions which will affect drainage are anticipated, they must be indicated.  Approval will be denied if adjoining properties are adversely affected by changes in drainage. 

• Construction materials must be stored so that impairment of views from neighboring properties is minimized.  Excess materials should immediately be removed after completion of construction. 

• No debris may be allowed to accumulate during construction.
