Quick Answers About Canby, OR ADUs
Market Context
Canby has a median home value of $500,000. Adding an ADU typically increases that by 25% — approximately $125,000 in added equity. A 1-bedroom ADU in Canby rents for approximately $1,562/month in the Clackamas County rental market , yielding a 4.3% cap rate on the investment. Occupancy averages 93% in this market.
Top Canby neighborhoods for ADU investment include Northside Canby (Knight Elementary / Canby Community Park), South Canby (Ackerman Middle / Baker Prairie), SE Canby, NE Canby, Faist Farms. Established R-1 single-family blocks with large ~8,000 sq ft lots, walking distance to Knight Elementary and Canby Community Park, driving steady school-and-family rental demand ideal for detached ADUs. Mature single-family neighborhood near Ackerman Middle and Baker Prairie schools with sizable R-1 lots and consistent rental demand from school staff and families.
Permit Process
Permit applications are reviewed by the Clackamas County Building Codes Division , with a plan check timeline of approximately 8 weeks. Permit fees in Canby range from $5,000 to $11,000 depending on project scope. Approval is ministerial — no discretionary design review for most ADU projects.
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.
"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."
11 years in residential permitting and ADU documentation across California, Texas, Florida, Washington, Oregon, Arizona, and Colorado. This guide was researched and verified against Canby's building department records and current 2026 Oregon's HB 2001 ADU law.
Property Eligibility
Is My Canby, OR Property Eligible for an ADU?
Canby homeowners are governed by Oregon's HB 2001 (2019). Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Canby under Oregon's HB 2001 (2019). No owner-occupancy requirement in Canby — you can rent both units as investment properties. Oregon doesn't set a fixed statutory review-day count the way California does — confirm the current timeline with the Clackamas County Building Codes Division.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under Oregon's HB 2001 (2019) — the exact number and type allowed depends on Canby's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 30% of Canby homes are in an HOA. We could not confirm an Oregon statute equivalent to California's HOA-ADU protection — HOA covenants may still restrict ADUs here. Our drawings include HOA submission formatting.
Always verify eligibility with Clackamas County Building Codes Division before designing.

Canby ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Canby construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 25% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

Local Zoning Rules
2026 Canby ADU Rules
Canby's 2026 ADU ordinance caps new units at 800 sq ft and 25 ft of height — on the tighter side, which narrows floor plan options. Setbacks run 5 ft side and 5 ft rear, close to the regional baseline. Because of Canby's Seismic Design Category D classification, structural drawings for a detached ADU here need a licensed engineer's stamp — architectural sheets for a code-compliant unit under the size cap generally don't.
Permit fees run $5,000–$11,000 — in line with what most homeowners budget for permitting, and plan check takes about 8 weeks at Clackamas County Building Codes Division. Submit directly to the department online — link below.
| Regulation | Canby Allowance |
|---|---|
| Max ADU Size | 800 sq ft |
| Max Height | 25 ft |
| Side Setback | 5 ft |
