RM-1 — Multiple-Family Residential
No district-wide numeric maximum building-coverage percentage is stated in Article 6 Chapter 1, to which Table 6 refers. Lot area/density, yards, building separation, parking and recreation requirements still constrain development. Section 138-6.104.H requires recreation area of at least 5% of gross development area, with each recreation area at least 5,000 square feet. This is not a 95% building-coverage allowance.
RMH — Manufactured Housing Park
No district-wide maximum building-coverage percentage is stated in Article 6 Chapter 4. Home-site area, building separation, streets and recreation constrain development. Parks with at least 50 sites require open space at least 2% of gross site area or 25,000 square feet, whichever is greater; perimeter buffers do not count. Do not infer a coverage percentage from that open-space requirement or import R-1 coverage from the height-only cross-reference.
MR — Mixed Residential (overlay)
Article 6 Chapter 5 does not set a separate maximum building-coverage percentage. Section 138-6.505 requires formal or active open space of at least 5% of gross lot area; it does not authorize 95% building coverage. Density, yards, site plan and other applicable standards remain in force.
