Custom 2 Bedroom Cottage Quadplex Development in Bend Oregon.
High-Return Middle Housing Infill Project
Zoning: Middle Housing- Quadplex (RS Zone)
Scope: Three Custom 2 Bedroom Cottages Added to an Existing Rental Home
By leveraging the City of Bend’s Middle Housing code, Tailored Homes helped transform a single-family rental property into a four-unit income-producing asset—without land acquisition costs while maintaining neighborhood compatibility.
Project Overview: Maximizing Rental Density Under Oregon Middle Housing Rules
Their objective was clear:Increase unit count, optimize cash flow, and maximize the property’s long-term value under Oregon’s new Middle Housing legislation.
Tailored Homes collaborated closely with the owners, a local civil engineer, and a designer to evaluate zoning allowances, site constraints, and infrastructure capacity. The optimal strategy was to retain the existing rental home and construct three detached 2-bedroom cottages, legally establishing the site as a quadplex under Bend’s Middle Housing code.
This approach allowed the owners to:
- Maximize rental income per lot
- Reduce per-unit construction cost compared to stacked multifamily
- Maintain strong tenant appeal with detached living units
- Increase long-term asset value and exit flexibility
Infill Construction Challenges—and How They Were Solved
Site Planning & Topography
The sloped backyard required a site plan that balanced:
- Drainage continuity for the original home
- City of Bend slope and grading requirements
- Private outdoor space for each cottage
Through close coordination with civil engineering and landscape professionals, the final layout delivered functional infrastructure and attractive tenant-ready outdoor environments.
Construction Access on a Constrained Lot
Backyard access for materials and equipment was limited. Tailored Homes implemented phased scheduling and logistics planning to minimize labor inefficiencies and protect the existing rental home during construction.
Utility Infrastructure & Coordination
A major complexity of this project involved separate utility distribution for three new detached units. Power, gas, water, and sewer systems were redesigned and installed in coordination with the City of Bend and local utility providers—without delaying the overall build schedule.
During excavation, an undocumented septic tank was discovered. The team immediately initiated permitting for abandonment and removal, resolving the issue quickly and keeping the project on track.
The final outcome:
- A fully legal quadplex in a high-demand Bend neighborhood
- Detached units with strong long-term rental appeal
- Optimized density without sacrificing design or livability
- A scalable model for investors pursuing Oregon Middle Housing and ADU strategies
