Summary

TABLE 50-14.5-1 R-1 DISTRICT DIMENSIONAL STANDARDS ... STRUCTURE HEIGHT Maximum height of bulding 30 ft. ... Exceptions to Building Height Limits Television and radio towers, accessory communications towers for private use, religious assembly or ornamental spires and towers, belfries, monuments, tanks, water and fire towers, stage tower or scenery lofts, cooling towers, chimneys, elevator penthouses, air conditioning penthouses, skylights, smokestacks, conveyors, storage elevators and facilities, flagpoles, accessory wind power equipment or accessory rooftop solar collectors
Full Breakdown
5-1 of the Unified Development Chapter (Chapter 50) sets the maximum height of a building in Duluth's R-1 Residential-Traditional district at 30 feet, the same flat limit that applies in the R-C, RR-1 and RR-2 districts, so the city treats 30 feet as its baseline single-family residential ceiling. 3 lists 'Exceptions to Building Height Limits' covering television and radio towers, accessory communications towers for private use, religious assembly or ornamental spires and towers, belfries, monuments, tanks, water and fire towers, stage towers or scenery lofts, cooling towers, chimneys, elevator penthouses, air conditioning penthouses, skylights, smokestacks, conveyors, storage elevators and facilities, flagpoles, accessory wind power equipment and accessory rooftop solar collectors, all of which may rise above the district's 30-foot limit.
In the Form District only, the spire and tower exception applies solely if the applicant proposes an Iconic Building, a limitation that does not reach the R-1 district. 5-1 is read together with the citywide exceptions list rather than as a standalone ceiling.
Violations & Fines
The building official administers Chapter 50 and will not approve a construction or alteration permit that would exceed the district height limit. Under Section 50-39.4, the property owner and any person who violates Chapter 50, including its height standards, is guilty of a misdemeanor and may be fined under City Code Section 1-7 or Section 12-6; the city may first issue a written compliance order under Section 50-39.2 giving at least 14 days to correct an over-height structure, and the penalty is waived if the violation is corrected within the stated time.
