Middle Housing

People who live in Gladstone — or want to — have different housing needs. More housing variety can help meet those needs. In many residential areas the city only allowed people to build new single-detached homes, a housing type that can be expensive and usually is occupied by homeowners rather than renters.

New zoning code for residential areas allows middle housing on all lots that also allow single detached homes. The intent for this new code is to increase the supply of middle and attainable housing and provide equitable access and housing choice for all.

 

What is Middle Housing?

A range of multi-unit or clustered housing types, compatible in scale with single-family homes, that help meet the growing demand for walkable, urban living, respond to household demographics, and meet the need for more housing choices at different price points. — DANIEL PAROLEK, author “Missing Middle Housing”

 

What are the different types of Middle housing?

Duplexes, triplexes, quadplexes, townhomes and cottage clusters. These housing types can be detached or attached, which helps with site design flexibility and can help maintain an existing house on the property. See images below for examples of each middle housing type.

 

What areas of Gladstone will be affected?

The code applies to all residential zoning districts citywide including: R7.2, RS and MR Zoning Districts.
