Zoning, building permits and septic rules in Canby, Oregon

Does Canby, Oregon have zoning, and what does it mean for your lot?

Yes. The City of Canby publishes a zoning and development code that governs land inside Canby city limits1. The City's index lists residential, commercial and industrial zones plus downtown and industrial-park overlays8. The zoning map and the "index of allowed uses" are on the Development Services page2.

Which district your lot sits in decides what you can build, so check the zoning map before you make an offer. We could not confirm Canby's rules on minimum lot size, setbacks, accessory dwellings, manufactured homes, RVs or tiny homes from the sources we reviewed, because those standards vary by district. Ask a planner at City of Canby Development Services; the department says "when in doubt, ask a planner"2. Clackamas County's separate zoning ordinance applies only to unincorporated land9.

Do you need a building permit in Canby, and who issues it?

Yes, building work in Canby is permitted, but in two steps. The City of Canby gives land-use approval first, and Clackamas County then issues the building, plumbing and electrical permits2. The City's own process states that the building permit will not be issued until the City has given an approval letter and all City fees are paid4. Both the City and the County charge review fees10.

For projects that need site and design review, the process includes a written decision and a 10-day appeal period, and the building permit cannot be issued until that period ends4. Canby has adopted the Oregon specialty building codes by reference11. Applications go through the county's Development Direct portal12.

How do septic permits work inside Canby?

Septic is a different question from building permits. Inside Canby, an owner whose building abuts a street or right-of-way with a City public sanitary sewer must connect within 90 days of official notice, provided the sewer is available at the property and the structure is within 100 feet of it5. Where no public sewer is available, the building sewer connects to a private system that must meet DEQ, the Oregon plumbing code and Clackamas County requirements13.

The Clackamas County Septic Program regulates septic installation, repair and maintenance for properties not served by community sewer14. Construction permits are needed to install, replace, repair or alter a septic system, and an approved site evaluation is required for most types3. We could not confirm a Canby-specific septic permit or inspection rule, so call the Septic Program at 503-742-4740 before you plan on a septic system within city limits14.

Can you live in an RV or tiny home on your land in Canby?

We could not confirm it. The City's zoning index did not show an operative rule on living in an RV, camping on private land or tiny-home occupancy inside Canby, so ask City planning before you buy or park anything. Clackamas County's rule allowing one RV as a second dwelling covers only unincorporated land outside cities15, so it does not answer the question for a lot inside Canby. Call City of Canby Development Services at 503-266-70012.

Building a home in Canby: the steps, in order

  1. Confirm the zoning district and allowed uses with City of Canby Development Services2.
  2. Check whether the lot is in a special flood hazard area; if so, a City development permit is required before construction or fill begins6.
  3. Get City land-use approval, including site and design review where it applies, and pay City fees4.
  4. Take the City's approval letter and approved site plan to Clackamas County for release of the building permit4.
  5. Arrange sewer connection with the City, or a county septic permit if no sewer is available53.
  6. Build under county inspections; the county does the final building inspection only after all other required inspections are approved16.

If you plan to build your own home, Oregon's owner-builder rule exempts an owner-built dwelling from the structural code's ceiling-height and room-size requirements, but a building permit is still issued7. We could not confirm a separate owner-builder rule inside Canby.

What stays with Clackamas County, and what to check before you buy in Canby

Outside Canby city limits, the county's rules apply instead: for land in unincorporated Clackamas County, see the Clackamas County page. Inside Canby, the county still issues the building permits2 and runs the septic program14; floodplain development permits inside the city come from the City6.

Before you buy, check the zoning district, flood hazard status, sewer availability at the lot line, and what the property tax will be. Clackamas County's effective property tax rate is 0.9%17. Oregon requires a state approach permit from ODOT for a new driveway connection to a state highway18; we could not confirm Canby's own driveway rule.

Watch-outs

  • The City of Canby does not issue building permits itself; Clackamas County does, and only after City approval and payment of City fees24.
  • Both the City and Clackamas County charge review fees, so budget for two sets of fees10.
  • We could not confirm Canby's setbacks, minimum lot size, building height, accessory dwelling or short-term rental rules; ask City planning at 503-266-7001 before you rely on any of them2.
  • A building permit cannot be issued until the 10-day land-use appeal period ends for projects that need site and design review4.
