169 Architectural Control Committee


Architectural Approval

All exterior additions and/or modifications to a home or lot in Thornhill require prior approval by the community's Architectural Control Committee (ACC). This includes exterior paint, siding, fences, windows, decks, mailboxes, screened porches and many other types of projects.  If you are not sure if your project requires prior approval, please reach out to Superior, or to the Board (This email address is being protected from spambots. You need JavaScript enabled to view it.) before getting underway.

Begin by reviewing the Community Guidelines, then fill out the Architectural Request for Approval Form that can be found on pps. 14-18 and submit it to Superior (This email address is being protected from spambots. You need JavaScript enabled to view it.). Be sure to fill out the form completely, including the Acknowledgement of Adjacent Owners section, and provide all supporting documentation.

Once Superior determines that your application is complete, it is passed to the ACC Committee for review.  ACC responds to most requests within 30 days, but large or complex projects may take longer.  Please note that the 30-day review period does not begin until the application is complete and sent to the committee. Missing information will result in a denial of your request. When ACC has reached a decision, you will be notified by Superior via email.  Be sure to factor the review period into your project plans and do not begin your project until written approval from ACC is received.

A note on mailbox replacement - An ACC application must be submitted for mailbox replacement.  The preferred mailbox style is similar to the Providence Crossing or Vineyard Grape styles offered by Watson Steel and Iron (with whom Thornhill has negotiation exception pricing).  Plastic or PVC mailboxes will not be approved.

Please submit ACC applications to: 

Superior Association Management, LLC.
P.O. Box 2427

As property owners, each of us has an obligation to maintain our homes and yards to an acceptable community standard.  Our property management company reviews and addresses complaints related to maintenance, and each month conducts a drive through of the community to note violations.  Common areas of concern are the condition of a home's exterior paint, excessive mildew, and damaged or rotten siding or trim work around windows and doors.  The yard items are most often related to excessive weeds, edging along the streets and walkways, dead trees, shrubs, and unkempt lawns and planting beds.  There are also municipal issues for which a lot may be cited, such as basketball goals and other items placed in the street, shrubbery at street corners blocking sight lines, low-hanging tree limbs over roadways and vehicles parked on lawns.

A little extra care around your home and grounds makes a big difference in how the community looks, and is an important part of the reason that Thornhill property values remain high.  If you receive a violation letter for an issue on your lot, please be sure to cure it within the time allotted, or reach out to Superior Management with questions, concerns or information about a repair plan. The typical cure period for a violation is 30 days, and failure to remedy it timely can result in daily fines.  We encourage members to address violation matters promptly!

Violation letters must be sent by US Mail and once mailed, an owner is considered notified. If you will be out of town for an extended period, please let Superior know. We also encourage members who travel to avail themselves of a free mail notification service called "Informed Delivery". To learn more about USPS's Informed Delivery service, click here.
