2025.docx 
Hi All,
 
I have another document for you to noodle.  The attached should be considered an outline to guide a discussion on a 
larger code amendment for duplexes. From my perspective, a duplex is just that, a single, sole use of a property.  The 
items I listed would envision just that; one duplex on piece of property.  With some basic design standards, we should 
be able to ensure compatibility when they’re building this on a common sized lot.  These lots are typically in areas 
where single family homes are prevalent.  If they are proposing multiple structures, it’s a multi-family development, 
and those standards kick in.
 
Anyway, food for thought.  Any and all input is welcome.

POTENTIAL CODE AMENDMENTS FOR DUPLEXES
1. Clarify that only one duplex is allowed per lot, without being subject to all 
multi-family development standards.  This would include density, setbacks, 
parking, accessibility, etc.
2. Clarify that only one kitchen is allowed per unit and that appliances, sinks, and 
accommodations that would support later installations are prohibited.  In short, 
no sinks and kitchen counters in individual units.
3. Like kitchens, clarify that one washer/dryer combo is allowed per unit.  It could 
be that one “housekeeping unit” per unit is allowed.
4. Eliminate the allowance for tandem parking for duplexes.  An alternative could 
be that it is only allowed for a single duplex, as the sole use of a property.
5. Clarify that all rooms, other than common space (kitchen, living room, and 
bathrooms) shall be considered bedrooms for the purposes of parking and 
occupancy limits.
6. Require a minimum of 150 sq. ft. of open space per unit.  This would be in 
addition to any required setbacks.
7. Consider requiring an increased setback for any duplex exceeding two stories 
in height.  For example, a 5’ setback for the first two stories, and 10’ for 
additional.
8. Consider a requirement for a front door, with covered porch (establish min. 
size) oriented to each street frontage.  Specify one primary entrance allowed 
per unit.
9. In new construction, where alley access is available, require all parking come 
from the alley.  New driveways are prohibited.  
10.In new construction, establish a maximum driveway width, and require a 
minimum separation (7’?) between individual driveways.  Also, include a 
minimum landscaped setback between driveways and the property line.  
11.Provide specific requirements for right-of-way improvements.  Curb, gutter, 
sidewalk, street widening, and alley paving.
12.Consider requiring a deed restriction, similar to the approach taken with ADUs 
for any new duplex.
