Cottage Clusters
Cottage Clusters Small Homes. Big Opportunity.
You don't have to build large to build well. Whether you are developing a community of compact homes around a shared courtyard, maximizing a single lot with multiple small dwellings, or responding to Oregon's growing demand for attainable housing, a well-planned cottage cluster delivers density without sacrificing character.
Serving Woodburn, Salem, Portland, and the surrounding Oregon communities, we turn Oregon's middle housing laws and your property's potential into clear, buildable plans.
Cottage Cluster Site Plans
Arranging multiple small homes on a single lot requires precise site planning. We design layouts that meet Oregon's cottage cluster standards for unit count, courtyard size, and setback requirements.
Individual Cottage Floor Plans
Each unit in a cottage cluster must function as a complete, comfortable home. We design efficient floor plans that maximize livability within the compact footprints Oregon's middle housing rules allow.
Shared Amenity & Courtyard Design
A cottage cluster is defined by its common outdoor space. We design courtyard configurations and shared amenity areas that satisfy code requirements and create genuine community appeal.
Our Process For Your Cottage Cluster
A cottage cluster involves multiple structures on a single lot, each meeting residential code independently while sharing site infrastructure and common space. Here is how we ensure success:
On-Site Consultation
We start by measuring your lot and studying the zoning designation. Unit count, courtyard dimensions, parking requirements, and utility connections all shape what your property can support before design begins.
Design & 3D Modeling
We draft the initial site layout and individual cottage floor plans. Using 3D modeling tools, we help you visualize how the finished cluster will feel from the street and within the shared courtyard.
Code Compliance
We refine the plans to meet the Oregon Residential Specialty Code and middle housing design standards. This includes energy calculations, seismic bracing considerations, egress requirements, and courtyard dimension standards.
Permit-Ready Docs
You receive a full set of plans—including site plans, floor plans, elevations, and cross-sections—ready to submit to your city or county building department
Frequently Asked Questions
Everything you need to know about the planning and permitting process in Oregon.
How many cottages can I build on my lot in Oregon?
Oregon's middle housing laws allow cottage clusters on any lot zoned for single-family residential use. The number of units allowed depends on lot size, with a minimum courtyard area required per unit. We review your specific parcel before design begins.
What is the difference between a Drafter and an Architect for a cottage cluster project?
For most residential cottage cluster projects, a licensed architect is not required. A professional drafter like Topline provides the technical drawings needed for permits and construction, often at a lower cost, while still ensuring code compliance and strong design.
Can a cottage cluster include an ADU in addition to the primary cottages?
Oregon's middle housing rules and ADU regulations interact in ways that vary by jurisdiction. We are familiar with how local cities and counties interpret these overlapping codes and will advise you on what is allowable on your specific property.
