Residential Design Criteria

The Lake Saint Louis Architectural Review Board’s mission is to promote an overall desirable visual appearance the City by ensuring that all proposed work brought for consideration of the board is appealing, compatible, and complimentary design and composition.

The Architectural Review Board (ARB) reviews designs for proposed new homes, additions and swimming pools.  Before a building permit is issued for most proposed residential construction within the City of Lake Saint Louis, the ARB must approve the project.  Certain residential developments within the City of Lake Saint Louis have had designs for their dwelling units previously approved by the Lake Saint Louis Planning & Zoning Commission.  The structures within those developments need not receive ARB approval.


In certain other areas, the Lake Saint Louis Community Association’s Architectural Control Committee decides the appropriateness of proposed colors, materials, and other matters.

Exterior Design, Finishes & Materials

Materials and finishes should be selected for their durability and wear as well as for their beauty.  All materials used on enclosures or additions must match the materials and architectural style of the existing house.


Generally, buildings are to be designed to be compatible with the topography and vegetation of the site so that grading and tree removal is minimized. Buildings are also to be designed to be compatible with adjacent or nearby structures in terms of scale. 

Similarity of Design

In areas within which the ARB has jurisdiction, new single-family residential structures with identical or similar front elevation designs are not permitted on lots within three hundred feet of each other. Such features as window style and placement, the size and configuration of the front elevation, roofline, and exterior materials should all be considered during the review of a proposed project.


Colors for residential dwellings must be compatible with neighboring residences, the natural surroundings, and with community standards. Identical color schemes are not permitted within two hundred feet, or four hundred feet in a cul-de-sac, of any lot line of a structure of the same color, unless previously approved by the Planning and Zoning Commission.

 Primary and secondary colors are not permitted.

Color selections may not be gaudy, garish, inharmonious or discordant in view of the range of colors in customary use throughout the neighborhood and the community at large. The color selection shall not be materially and obviously dissimilar to the exterior color selections of other buildings in the surrounding neighborhood or to the range of colors in customary use in the community at large as to appear to be jarring, clashing, exotic or bizarre. However, reasonable variations in individual exterior color schemes may be permitted.


Residential foundation landscaping shall consist of:

  • May include ornamental trees (less than 30 feet height at maturity) in planting:
    • Minimum of 3 feet between plantings and property line
    • Minimum of 3 feet between plantings and structure
  • Minimum of 1 shrub for every 5 feet of foundation - corner to corner
  • Minimum of 18 inches height at installation
  • Mix of evergreen and deciduous shrubs

Trees shall not be counted “in lieu” of shrubs
