Do you need a building permit in Marion County, Oregon?

Yes. Unincorporated Marion County requires a permit to construct, enlarge, alter, move or replace a home or related structure¹². A carport, garage or shed also needs a structural permit when it is larger than 200 square feet, or when it exceeds 10 feet from finished floor to the top plate even at a smaller size². Listed minor work can be permit-exempt, including replacement doors or windows in existing openings and patios or decks no more than 30 inches above grade, but the work must still meet code². A qualifying agricultural, forestry or equine building can receive a county-approved structural-code exemption, but it cannot be a dwelling and electrical, plumbing and mechanical permits still apply¹¹. Oregon's owner-builder exemption only relaxes specified structural-code rules for ceiling heights, room sizes and temperature levels; it does not waive the building permit⁹.

Who is the Marion County building department, and how do you reach them?

Marion County Building Inspection is the building permit office for unincorporated Marion County at 5155 Silverton Road NE, Salem, OR 97305; call 503-588-5147 or email [email protected]¹⁵. The office does not start new applications or release permits with a balance due after 4:30 p.m.¹⁵. Building Inspection reviews new-construction and remodeling plans in unincorporated Marion County and in cities without their own building-inspection programs¹⁵. Jurisdiction can vary by permit type in incorporated cities that contract with Marion County, so confirm the correct issuer before applying¹. Oregon ePermitting lets applicants in participating jurisdictions track status, pay fees, upload documents, schedule inspections and review results, but each jurisdiction decides which permits it sells online¹⁶. Residential structural fees use the ICC valuation table current each April 1, while alteration and repair valuation is set by the building official at fair market value¹⁷.

Does Marion County have zoning?

Yes. Marion County administers Title 17 outside urban growth boundaries and Title 16 for unincorporated land within urban growth boundaries; parcel-specific rules depend on the mapped zone³. Marion County will not issue a building permit when the proposed use violates a county ordinance⁶. New farm parcels in the Exclusive Farm Use zone use a local-average calculation, rounded to the nearest 10 acres, with an 80-acre minimum floor and additional land-division criteria or exceptions¹². New EFU structures generally have 20-foot front, rear and side setbacks, while certain qualifying older small parcels have a reduced side-yard exception and nonfarm dwellings can face a 200-foot setback from abutting farm or timber land¹⁸. EFU dwellings generally have a 35-foot height limit¹⁹. Those EFU figures do not answer other zones: ask Marion County Planning at 503-588-5038 to identify the parcel's zone and applicable standards²⁰.

How do septic permits work in Marion County?

Marion County Building Inspection issues septic-system permits throughout Marion County as a contract agent of the Oregon Department of Environmental Quality⁵⁸. A permit is required for new onsite systems and for many alterations, repairs and connections; the process can require a site evaluation, application materials, fees and county inspection⁷. Only 7.7% of Marion County soils lack severe limitations for a conventional drain field, so arrange the site evaluation before fixing a house location or budget²¹. Oregon generally requires a property to connect when a public or community sewer is legally and physically available, although exceptions and local service-area rules matter²². Composting toilets are allowed only under state standards, and they do not eliminate lawful graywater disposal or an otherwise required sewer connection²³. Call Building Inspection at 503-588-5147 for the correct septic application path⁸.

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

Marion County allows an RV to be occupied on an unincorporated property that already has a dwelling for no more than 120 days in a calendar year; a qualifying hardship dwelling is a separate path¹⁰. The RV must have the owner's consent, safe approved water and sewage disposal, and compliance with applicable sanitation, plumbing, electrical and sewerage standards¹⁰. A tiny house on wheels cannot be used as a permanent dwelling in Marion County's urban or rural unincorporated areas; the identified exception for a structure on wheels is temporary RV use for a medical hardship¹³. A non-wheeled tiny house can serve as an accessory dwelling unit in an urban growth-boundary area outside city limits if it meets the urban ADU standards¹⁴. That urban ADU needs a building permit, is capped at 900 square feet or 75% of the main dwelling footprint, whichever is less, and may be detached only in the zones that allow that form¹⁴. Ask Marion County Planning how the parcel's zone treats the proposed unit²⁰.

How do you build a home in Marion County, step by step?

Ask Marion County Planning to identify the parcel's zone and confirm the proposed dwelling, setbacks and access before design work begins²⁰³.
Determine whether public sewer is available; otherwise begin the county septic site-evaluation and permit process early²²⁷.
If the landowner will personally construct, alter or abandon a well, obtain the Oregon Water Resources Department landowner permit before work begins²⁴.
Obtain a Marion County access permit when creating, rebuilding, widening, improving or changing the use of an access within the covered public right-of-way²⁵²⁶.
Submit the home plans and permit application to Marion County Building Inspection¹¹⁵.
Schedule the project-specific inspections; typical stages include footing, foundation, utilities, framing, insulation and final inspections²⁷.
Before occupying a new dwelling or townhouse, provide the required contractor information and receive the residential certificate of occupancy²⁸.

What should you check before buying land in Marion County?

Confirm the parcel's zone, allowed dwelling type, setbacks and lot-creation history with Marion County Planning before assuming that acreage alone makes it buildable²⁰³. Ask the Marion County Floodplain Program to check whether the parcel is in a flood-hazard area because floodplain or floodway development usually requires permit review and approval²⁹. Only 7.7% of Marion County soils lack severe limitations for a conventional septic drain field, so make septic feasibility a purchase contingency²¹. A landowner who personally constructs, alters or abandons a well must obtain a state landowner permit before starting work²⁴. Check whether driveway work needs a county access permit; the covered process has a $50 fee and applies within the public right-of-way²⁵. About 53.3% of county land has a slope of 15% or less, while 53.2% is wooded, so clearing, grading and access costs can differ sharply by site³⁰³¹. The effective property-tax rate in Marion County is about 0.9%, and the median annual property-tax bill is about $3,382³²³³.

Watch-outs

The 120-day RV allowance applies to an unincorporated property with a dwelling; it is not blanket permission for full-time RV living on vacant land¹⁰.
A tiny house on wheels cannot be used as a permanent dwelling in unincorporated Marion County; ask Marion County Planning about the separate medical-hardship RV path or a code-compliant non-wheeled unit¹³²⁰.
We could not confirm a countywide minimum dwelling size or a complete countywide lot-coverage rule; ask Marion County Planning for the standards attached to the parcel's mapped zone²⁰.
