More homes on one lot, for landowners and developers.
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.
A lot that held one house can now hold several. Bring the address and we tell you how many fit.
A group of small homes around a shared courtyard. GenTerra built the first cluster the City of Gresham approved.
Two, three, or four homes on one lot. Rent them, sell them, or keep one for family.
Attached townhomes, or splitting a large parcel into buildable lots. We check which path is shorter.
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.
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 the zoning allows on your lot, how many units fit, and whether a cluster on one lot or a subdivision is the shorter route.
We work with an architect on the unit plans, the site layout, and the shared courtyard.
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.
One general contractor managing the whole site, from utilities to final inspection.
"They took our lot from a zoning question to four finished cottages around a courtyard. One contractor the whole way."
Placeholder review. Replace with a real one."We split the parcel and built a fourplex on half. They knew the middle-housing rules cold and kept the city moving."
Placeholder review. Replace with a real one."First cottage cluster our city had seen. GenTerra had done it before, and it showed."
Placeholder review. Replace with a real one.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.
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.
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.
Our Gresham cluster ran about a year from ground-breaking to finish, plus the design and permitting time before that.
