The Covenants and Standards, which apply to all properties in The Woodlands, require that the placement, construction, alteration or repair of any temporary or permanent structure or improvement on a lot with an existing single family dwelling must have the prior written approval of the Residential Design Review Committee or their designated staff. In addition to the Standards, Neighborhood Criteria establish more specific regulations which vary from one neighborhood to another. All improvements must also comply with the Neighborhood Criteria applicable to that lot.
