Additional dwelling. Exceptional standard.
An ADU (Additional Dwelling Unit) or SDU (Secondary Dwelling Unit) is a self-contained living space on your existing property — a garden suite, laneway house, or detached unit with its own entrance, kitchen, and bathroom.
Whether it's for aging parents, adult children, rental income, or a private home office — we deliver a turnkey unit built to the same standard as our custom homes.
No subcontractor runaround. No separate firms for design, engineering, and permits. One team handles everything.
Our Turnkey Process
Five phases. One team. Zero gaps.
Every ADU and SDU project moves through our full-service pipeline — designed to eliminate the chaos of coordinating multiple firms.
01
Consult
We assess your property, zoning, goals, and budget. You leave with a clear picture of what's possible.
02
Design
Custom architectural design tailored to your lot, lifestyle, and the character of the main home.
03
Engineer
Structural, mechanical, and site engineering handled by D.E.C.C Inc. — fully integrated with our build team.
04
Permit
D.E.C.C Inc. manages the full permit application and approval process. No back-and-forth on your end.
05
Construct
Frisina Build executes the construction — premium finishes, clean site, disciplined schedule, and hands-on leadership.
Engineering & Permit Partner
D.E.C.C Inc.
Our ADU/SDU program is powered by a direct partnership with D.E.C.C Inc. — handling all structural engineering, mechanical design, and permit submissions. This integration eliminates the delays and miscommunication that come from managing separate engineering and permit firms.
One scope. One timeline. One point of accountability from design through approval.
Why Frisina Build
