Do you need a building permit in Independence, Oregon?
Yes. The City of Independence requires a building permit to construct, enlarge, alter, move or demolish any one- or two-family dwelling or related structure inside city limits1. Oregon runs one statewide building code, which cities and counties administer10. Some minor work is exempt, so ask the city before assuming a small project needs nothing1.
Before anyone moves into a new home, the building official must issue a certificate of occupancy, unless a temporary certificate is issued11. The city's land is separate from unincorporated Polk County, where the county processes building permits outside city limits12.
Who issues building permits in Independence, and how do you reach them?
The City of Independence Building Department issues building permits inside city limits, and applications and inspection requests go through Oregon ePermitting413. The city says it no longer takes phone or email inspection requests4. For questions, call 503-837-1177 or email permits@ci.independence.or.us13.
Electrical permits are the exception: Independence sends them to Polk County4. The city publishes a permit fee schedule and calculator, and it sets the actual fee by permit type14.
Does Independence, Oregon have zoning?
Yes. Land inside Independence city limits is zoned under the Independence Development Code, and the city asks applicants to consult with it on which requirements apply2.
In the Low-Density Residential (RS) zone, a detached single-unit home needs a lot of at least 4,800 square feet7. Primary structures in RS need front and rear setbacks of at least 10 feet and a side setback of 5 feet, or 10 feet on a corner lot15. Residential buildings in RS may rise to 35 feet16. Other zones have different numbers, so confirm the district for your lot with the city.
Individual manufactured homes are a permitted use in any zone where single-family homes are permitted6. The home must be multi-sectional, double-wide or wider, and enclose at least 1,000 square feet17. They cannot go in a historic district6.
How do septic permits work in Independence, Oregon?
We could not confirm who administers onsite septic systems inside Independence city limits, or what inspections apply there. Call Polk County Environmental Health and the city building department before you count on a septic system3.
City services are the default for new lots. Lots in a subdivision must be served by a city water supply system and a city sewage disposal system18. For land outside city limits, Polk County conducts septic site evaluations and issues septic permit specifications8. Water-supply wells are separate: a landowner who builds a well needs a state permit, a $550 fee and a $10,000 bond or letter of credit, unless a licensed well constructor does the work9.
Can you live in an RV or tiny home in Independence, Oregon?
Only briefly. Outside a designated RV park, a camper or RV may be used for sleeping or living for up to 15 days after the owner first gets a temporary-stay permit from the City, and the city issues that permit once per vehicle per calendar year5. RV living is also allowed in designated areas of manufactured-dwelling parks under additional standards5.
We could not confirm a city rule for tiny homes, so call the City of Independence building department at 503-837-1177 before buying a lot for one13. A manufactured home is the better-documented path: it needs to be a double-wide or wider and at least 1,000 square feet17.
Building a home in Independence, Oregon: the steps, in order

- Check whether the lot is in the special flood hazard area, where a development permit is required before construction or fill19.
- Apply for the building permit online through Oregon ePermitting4.
- Arrange electrical permits through Polk County4.
- Schedule inspections through the online portal4.
- Get the certificate of occupancy before anyone moves in11.

Watch-outs
- The city's building page says a new building official is coming, so confirm the current contact before relying on any staff name or inspection schedule13.
- We could not confirm who handles septic systems, short-term rentals or driveway access permits inside Independence city limits; ask the city building department and Polk County Environmental Health3.
- Do not apply Polk County's unincorporated-area rules, such as its accessory dwelling or lot-size rules, to a lot inside Independence; the city's own code controls there2.
