Summary
A single-family detached dwelling in Dubuque's R-1 district is capped at 30 feet under the Bulk Regulations table. Institutional uses like a place of religious exercise or school in the same district can reach 75 feet, but only by adding a foot of yard setback on every side for each foot the building exceeds the base 30-foot limit.

Full Breakdown
Section 16-5-2-7's Bulk Regulations table sets the maximum height for a single-family detached dwelling in R-1 at 30 feet, the same figure applied to bed and breakfast homes, licensed adult day services and childcare centers in that district's table. A place of religious exercise or school in R-1 carries a separate 75-foot maximum, but footnote 1 to the table conditions that taller allowance: the building must provide at least one additional foot of yard space on all sides for every additional foot by which it exceeds the district's ordinary height limit, trading extra height for extra setback. Section 16-3-10 separately allows specific building features, chimneys, cooling towers, condensers, elevator bulkheads, belfries, stacks, ornamental towers, monuments, cupolas, domes, spires, stair towers and similar mechanical appurtenances, to exceed the prescribed height limit as long as they are required for a permitted use, though an equipment penthouse cannot make up more than 30 percent of the roof area under that same exemption.
Violations & Fines
Building a single-family home taller than the R-1 table's 30-foot limit, or an institutional building exceeding 75 feet without providing the required added yard setback, is a municipal infraction under section 1-4-2, carrying a civil penalty of up to $750 for a first offense and up to $1,000 for repeat offenses, with each day of the violation a separate offense.
