Summary
The Lake County UDO caps building height by district. R-1 residential allows 2.5 stories / 35 feet, while R-2 and R-3 allow 2 stories / 25 feet. Chimneys, steeples, and similar features may exceed the limit.
Building height is measured as the vertical distance from average grade at the street side of the building (along the building base) to the highest point ... to the mid-point between the eaves and peak of the principal roof structure for hip, gabled, and gambrel roofs.
Full Breakdown
Under Table 2-3 of the Lake County UDO, maximum building height in the R-1 district is 2.5 stories or 35 feet; R-2 and R-3 districts allow 2 stories or 25 feet. Building height is measured from average grade at the street side of the building to the highest point (or, for pitched roofs, the mid-point between eaves and peak). A 'half-story' is space under a sloping roof where the roof-decking/wall intersection is not more than 3.5 feet above the top floor. Elevators, stairways, fire or parapet walls, steeples, cupolas, flagpoles, chimneys, smokestacks, silos, and similar structures may exceed the height limit provided they are not used for human occupancy.
Violations & Fines
A building exceeding district height is a nonconforming or violating structure; unresolved zoning violations are nuisances per se carrying citation penalties up to $2,500 (first) and $7,500 (subsequent) under IC 36-1-3-8.
