A “sunroom” is a patio enclosure constructed with glass walls. Glass roofing is not permitted for sunrooms. Building permits from League City are required prior to ARC approval.
Location:
Sunrooms may not encroach on any utility or drainage easement (unless the utility companies involved have granted their written consent to such encroachment), nor may it violate the building setback lines applicable to the residential dwelling on any lot. Sunrooms must not interfere with drainage or cause water to flow onto any adjacent lot. Sunrooms must be located in the rear yard and must be a minimum of five (5) feet from side fence lines and eight (8) feet from the rear fence line.
Material:
Supporting structural members must be of a color and shade similar to and harmonious with the exterior of the residence. Glass must be tinted in a shade compatible with the exterior of the residence. No metallic or direct reflecting style shading/tinting of the glass will be permitted. Applicants may be required to submit actual samples of the glass with the proposed shading/tinting material applied for approval. Additional landscape screening may be required.
Prohibited Accessories:
No sunroom shall have exposed air conditioning or heating duct work installed on the exterior thereof. HVAC vents must be attached to the main residence. No ductwork shall be visible. Window coverings are not required; however, only interior covering will be permitted; there shall be no exterior coverings of the sun room glass permitted.
Dimensions:
The lowest point of the sunroom may not exceed nine (9) feet from ground level (typical first floor plate height). The sunroom roof shall provide an attractive slope with a minimum 4/12 roof pitch away from the house, at an angle that does not exceed that of the roof of the residence. Flat roof sunrooms are not permitted. The sunroom shall not protrude from the sides of the residence. Sunrooms may not encroach the building line.
Modifications:
If a patio is modified as a part of a sunroom project, the patio modification shall abide by the Patio ARC Guideline.
