Cottage Clusters & Middle Housing

Cottage Cluster and Middle Housing Builder in Gresham

More homes on one lot, for landowners and developers.

What is middle housing?

Middle housing is everything between a single-family house and an apartment building: duplexes, triplexes, fourplexes, townhouses, and cottage clusters, usually on one lot. Oregon's House Bill 2001 requires Portland-metro cities, Gresham included, to allow these in residential zones that used to permit only one house per lot. A cottage cluster is a group of small homes arranged around a shared courtyard, and the cottages can sit closer together than the rules for a single house would normally allow.

What you can build

A lot that held one house can now hold several. Bring the address and we tell you how many fit.

Cottages and a courtyard

Cottage Clusters

A group of small homes around a shared courtyard. GenTerra built the first cluster the City of Gresham approved.

Two to four homes

Duplexes and Fourplexes

Two, three, or four homes on one lot. Rent them, sell them, or keep one for family.

Rows and lots

Townhomes and Land Division

Attached townhomes, or splitting a large parcel into buildable lots. We check which path is shorter.

For landowners and developers

A lot that could hold one house can now hold several, and in many cases you can do it without subdividing, which means fewer permits and a shorter path. Owners use this to add rental units on a large residential lot, to split a parcel and develop one half, or to build for family. We recently worked with an owner dividing a parcel to keep a daycare on one side and put a fourplex on the other. Every project starts with the zoning, and that is where we start too.

Our work

The first approved cottage cluster in the City of Gresham. About a year from a bare lot to finished homes, we sat with the architect on the cottages, handled every permitting step, and managed the build.

What we handle

1

Feasibility

What the zoning allows on your lot, how many units fit, and whether a cluster on one lot or a subdivision is the shorter route.

2

Design

We work with an architect on the unit plans, the site layout, and the shared courtyard.

3

Permitting

Joel Kastel, GenTerra's owner, worked on the city's side of permitting. He assembles the submission, coordinates engineers, and works through the city's comments.

4

Construction

One general contractor managing the whole site, from utilities to final inspection.

What owners say

"They took our lot from a zoning question to four finished cottages around a courtyard. One contractor the whole way."

"We split the parcel and built a fourplex on half. They knew the middle-housing rules cold and kept the city moving."

"First cottage cluster our city had seen. GenTerra had done it before, and it showed."

Middle housing questions

Do I have to subdivide my lot to build middle housing?

Often no. Oregon's middle-housing rules allow several homes on one lot in residential zones. Subdividing is an option when you want to sell the homes separately, and we walk through both paths with you.

Can the cottages be sold individually?

Yes, through a subdivision or a condominium structure. Many owners keep the cluster and rent the units. The right structure depends on your goals, and your attorney sets it up.

How many homes can I fit on my lot?

It depends on the lot size, the zone, and the setbacks. Bring the address and we tell you how many the city will allow and where they fit.

How long does a cottage cluster take?

Our Gresham cluster ran about a year from ground-breaking to finish, plus the design and permitting time before that.

Where do you build middle housing?

Gresham, Portland, and East Multnomah County. See our service area.
