The Downtown-wide Design Guidelines and Neighborhood Design Guidelines will ensure that what is built in the Downtown will be attractive, aesthetically coherent, practical, and of beauty and value. Specifically, the Guidelines will show how buildings and landscapes support and reinforce physical, three-dimensional intentions of the Plan and create places containing pleasing proportions, scale, and character that people will want to inhabit. The Guidelines also lay out the framework for developing a community’s sense of place and its identity and connection to the region.

The Howard County Zoning Regulations allow for "active adult housing" as either a conditional use in residential zoning districts or as a permitted use in other zoning districts. Age-restricted developments must be appropriately designed for adults at least 55 years of age. Site improvements must ensure accessible routes between parking, dwelling units, and common areas. Individual dwellings must incorporate universal design features to be adaptable for residents with mobility and functional limitations that often result from aging.

Adopted in 1998, the Guidelines describe the architectural and landscape elements that reflect Ellicott City's history and suggest guidelines for rehabilitation and new construction that will best preserve the town's historic character. The guidelines provide a framework for the Historic District Commission's review of applications and help property owners plan their projects and prepare applications for the Commission. Guidelines do not dictate specific solutions that must always prevail; they are not regulations. Their purpose is to provide consistent ground rules for residents and the Historic District Commission, while allowing creativity and individual solutions.
Adopted in 1995, the Guidelines describe the architectural and landscape elements that determine the historic character of Lawyers Hill and suggest guidelines for rehabilitation and new construction that will best preserve the neighborhood's character. Local historic districts safeguard the heritage of the County by preserving the historic cultural, social, economic, political and architectural elements that characterize these districts. To carry out this purpose, Title 16, Subtitle 6 of the Howard County Code establishes the Historic District Commission and authorizes the Commission to review exterior alterations to properties in designated historic districts.
