Exterior Modifications
Exterior Modifications All exterior alterations or improvements to properties in Stillwater must be reviewed and approved before construction by the Architectural Control Committee (ACC). Residents must submit a home improvement application describing the work to be performed. The ACC will review the request and render a decision. If the request is not approved as submitted, the ACC may provide suggestions for making changes so it can be resubmitted for approval.  

As soon as you have gathered your information, you are ready to get started!  

To complete your application, click on Ask. Request. Submit. tab at the top of this page and select “Make a Home Improvement Request.” Once you have opened the form, enter all the information needed for the committee to make an informed decision. Any applications dealing with the house’s exterior appearance (such as painting or roofing) must be accompanied by project details, or the application might be disapproved for lack of information. Also, remember to include a plat map or survey of the property that indicates the project in conjunction with the property lines and easements when applicable.
