Full Breakdown

Carmel regulates building height by zoning district, not a single citywide cap. UDO Section 5.14 (HT-01: General Height Standards) provides that maximum and minimum heights 'shall be as indicated on the two-page layout for the subject zoning district in Article 2.'

Height for pitched-roof buildings is measured from the midpoint of the pitched roof.
