Zoning Handbook

The Capitol Hill Commercial Mixed-Use zones include the MU-25 and MU-26 zones and are intended to:

  • Encourage the adaptive use and reuse of existing buildings, many of which are located in the Capitol Hill Historic District, particularly with respect to the portions of the buildings that exceed the commercial floor area ratio permitted in the underlying zone districts;
  • Concentrate non-residential uses in commercial zone districts in certain areas of Capitol Hill, thereby enhancing and protecting the residential character of the areas surrounding the commercial zone districts and relieving pressure to use properties zoned residential for commercial uses; and
  • Provide appropriate incentives for new infill construction that is compatible with the Capitol Hill Historic District and its predominance of low-scale row house structures.

The MU-25 zone is intended to permit moderate-density mixed-use development.
