Architectural Design Guidelines

Article 2 of the Mayfield Declaration Document requires all homeowners to obtain pre-approval from the Design Review Committee (DRC) before making certain improvements (defined in paragraph 1.6) to their Lots. Homeowners must complete and submit to the DRC a design review request (DRR) form. (Click on the link below to open and save a blank copy of the DRR form.) Per paragraph 2.5 of the Declaration Document, DRR forms are considered automatically disapproved if the DRC does not respond within 45 days of receipt of the DRR form.

The DRC’s policy is to approve or reject DRR forms based on the DRC’s architectural policies and design standards. A copy of the DRC’s current Architectural Design Guidelines can be opened and/or downloaded using the link below. Homeowners submitting a DRR form must indicate on their DRR form that they are familiar with the DRC’s current architectural policies and design standards.

City Permits

Homeowners are responsible for contacting the City of Thornton to determine whether a permit from the City must be obtained. Receiving approval for a project from the Design Review Committee does not mean the project will be approved by the City and vice versa. Installation of sheds, driveways, driveway extensions, sidewalks, fences and trees are a few types of projects that require approval from both the DRC and City of Thornton.
