Summary

In the City of Oregon, Ohio's Advanced Manufacturing District, Codified Ordinances Section 1145.04(d) caps maximum lot coverage at eighty percent (80%), meaning buildings, parking, loading areas and other coverage cannot occupy more than four-fifths of a development site in that district.

(d) Maximum Lot Coverage: Eighty percent (80%).

Full Breakdown

04, the Advanced Manufacturing District's Development Standards section, sets a hard numeric ceiling on how much of a site can be covered: subsection (d) caps 'Maximum Lot Coverage' at eighty percent (80%), immediately after the section's front, side and rear setback figures in subsections (a) through (c) and just before the 60-foot maximum building height in subsection (e). 07(b)(1). 06(c) adds a continuous screening requirement along the entire shared boundary, either a row of shade trees and a double hedge, a 6-foot wall or fence plus hedge and shade trees, or a double staggered row of evergreens.

Ordinance 066-2022, passed March 28, 2022, adopted the 80% cap along with the rest of the district's dimensional standards when Council created the Advanced Manufacturing District.

Violations & Fines

Exceeding the 80% lot coverage cap, or occupying the required landscape and buffer area with building, parking or storage, is a Zoning Ordinance violation. Section 1105.99 makes such a violation a misdemeanor with a fine of up to $100 plus costs, and treats each day the excess coverage continues after notice as a new, separately chargeable offense against the owner or developer.

Frequently Asked Questions

What is the maximum lot coverage in Oregon's Advanced Manufacturing District?
Eighty percent. Section 1145.04(d) caps combined building, parking, loading and paved coverage at 80% of the lot in the Advanced Manufacturing District, leaving the remaining area for the district's required front, side and rear setbacks and landscaping.
Does the uncovered 20% have to be landscaped?
Effectively, yes. Section 1145.06 requires a landscaped zone at least 40 feet wide along the right-of-way, planted parking islands, and, where the site borders a residential use, a continuous screening buffer of trees, hedges or a wall along the shared property line.
Does the 80% cap apply outside the Advanced Manufacturing District?
No. Section 1145.04(d) is written specifically for the Advanced Manufacturing District created by Ordinance 066-2022; other Oregon zoning districts set their own dimensional standards in their own chapters rather than sharing this figure.
What happens if a development in the AMD exceeds the coverage cap?
It is a Zoning Ordinance violation under Section 1105.99, a misdemeanor punishable by up to $100 plus court costs, with each day the excess coverage continues after notice from the Zoning Inspector treated as a separate offense.
