Local Intelligence
What Canby Homeowners Need to Know Before Submitting
Size & Zoning Rules
Any new square footage added to your Canby home counts against the same zoning envelope that governs ADU size, meaning large additions may affect your ability to add a future ADU. Canby's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
Canby does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
If the addition creates a second unit or is later converted to a rental, Canby's ADU market supports approximately $1,544/month for a 2-bedroom unit.
Permit Process & Fees
Clackamas County Building Codes Division permit fees for this project type typically range from $5,000 to $11,000 depending on project valuation and scope. Plan check runs approximately 8 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Addition permit packages submitted to Clackamas County Building Codes Division must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural drawings are always required for any load-bearing elements, second-story work, or new foundation.
Visit Clackamas County Building Codes Division ↗⚠ Common Pitfall in Canby
Because Canby sits on ground classified as Seismic Design Category D, Clackamas County will scrutinize your engineer's lateral bracing and foundation details closely during plan review, which is often what drags a straightforward ADU review past the typical 8-week estimate. Many Canby lots also still run on older sewer laterals installed before the city's newer subdivisions, so the county may require a sewer scope inspection to confirm the line can handle a second unit — an extra step that can add another inspection cycle if the pipe needs relining. Because the county handles plan review instead of the city itself, expect to submit through Clackamas County's online portal rather than at Canby City Hall, which trips up homeowners who assume local staff will guide them through the process in person.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Canby ADU projects, that per-sqft cost figure is really a state-level estimate rather than a Canby-specific number, so I'd get two or three local contractor quotes before you budget off it — and I'd also call Clackamas County Building Codes Division directly, since the 8-week timeline can stretch if your drawing set comes back with corrections on first submittal."

What drawings are required to permit a home addition in Canby? +
Canby's building department requires: a site plan showing the addition's footprint and setbacks, floor plans for all affected levels, all four exterior elevations, an electrical plan, and energy compliance (Title 24 in California). Structural plans stamped by a licensed engineer are required for any load-bearing elements — included in our Premium package.

What setbacks apply to home additions in Canby? +
Canby enforces minimum setbacks from property lines for all additions: typically 4–5 ft side setbacks and 5 ft rear setbacks, though these vary by zoning district and lot size. Your addition must stay within the buildable envelope. Our site plan documents existing and proposed setbacks and flags any zoning variances required.
Do I need structural drawings for a home addition in Canby? +
Yes, for most additions. Any load-bearing walls, new foundations, second-story construction, or roof structure changes require stamped structural drawings from a licensed engineer. California's CBC (California Building Code) and seismic requirements make structural plans mandatory for most addition types. Our Standard and Premium packages include stamped structural drawings.

Will a home addition increase my home's value in Canby? +
In Canby, where median home values are approximately $500,000, a permitted home addition adds square footage that appraisers value as part of the home's gross living area. Return on investment varies by addition type — master suite additions, family room expansions, and additional bedrooms typically recoup 50–75% of project cost in appraised value in OR markets.
Can I add a second story to my home in Canby? +
Second-story additions are permitted in most Canby residential zones, subject to height limits and design review requirements.
