Building height in McKinney, TX

What the McKinney zoning ordinance says about building height, district by district. Section numbers link to the official ordinance.

R43 — Residential Estate

Maximum 45 feet. Measured from the average of the highest and lowest grade points of the lot to the highest point of the structure; roofs sloped 5:12 or greater are measured to the roof midpoint (Sec. 204EE).

UDC Table 2-3 (Sec. 204D); Sec. 204EE

C1 — Neighborhood Commercial

Maximum 35 feet. Mixed-use residential and multi-family buildings in this non-residential district follow Sec. 206G instead.

UDC Table 2-13 (Sec. 204N)

AG — Agriculture

Maximum 35 feet (Table 2-21). The linear PDF text extraction had dropped this figure from the height row, but the source table image prints it clearly, matching Table 2-25's non-residential summary.

UDC Table 2-21 (Sec. 204V); Table 2-25

AP — Airport

Maximum 45 feet, but no structure may exceed FAA height regulations or Chapter 118 of the McKinney Code, whichever is more restrictive (Sec. 204EE).

UDC Table 2-22 (Sec. 204W); Sec. 204EE

HC — Highway Commercial Overlay

Four subzones along University Drive (US 380), the Central Expressway/Sam Rayburn Tollway corridor (US 75/SH 121), and similar regional highways: Suburban (no height increase over the base district), Low-Rise (non-residential buildings up to 3 stories), Mid-Rise (up to 6 stories with a Sec. 203G.1 design exception), and High-Rise (up to 12 stories). Where the HC Overlay conflicts with the base district, the more permissive standard controls, except in the Suburban Subzone where the more restrictive standard controls.

UDC Sec. 204AA

All districts

Building height is measured from the average of the highest and lowest grade points of the lot to the highest point of the structure (to the roof midpoint for slopes of 5:12 or greater). Cooling towers, chimneys, and vent stacks may exceed the district maximum by up to 5 feet. Height cannot exceed FAA regulations or Chapter 118 (Airport Height, Hazard, and Land Use Regulations) where applicable, whichever is more restrictive. Religious assembly primary structures may reach up to 75 feet with increased setbacks and a landscape buffer, in most districts except MTC.
