D-MU Detached Dwelling Mixed-Use Overlay Zoning Districts address those areas of detached dwelling development where a mixed-use environment is desired, where some detached dwellings are used for residential uses and others for first-floor non-residential uses. These Overlay Districts are tied directly to the underlying detached residential district in order to maintain the existing character of the development and the neighborhood. Non-residential uses are restricted to only those uses that are compatible with residential uses. Ord. 16-581 Ord. 17-015
