Lane County

Running from the Willamette Valley to the coast, and one of the small number of counties to have adopted both optional rural housing statutes — rural accessory dwelling units by ordinance in 2023, and recreational vehicles as rental dwellings. Two things make its resource land unusual. Its forest land is split into two zones that differ sharply on dwellings: the Impacted Forest zone carries the template, lot of record and large tract routes, while the Nonimpacted Forest zone carries none of them. And it is one of only two Oregon counties with a Marginal Lands designation, applied to resource land that met neither the farm nor the forest productivity tests, where a dwelling on a vacant parcel created before 1 July 1983 is listed as permitted outright.

District codes checked against the county code. District codes are taken from the Lane Code Chapter 16 table of contents and the zone articles themselves, as published May 2026: Nonimpacted Forest Lands (F-1) at 16.210, Impacted Forest Lands (F-2) at 16.211, Exclusive Farm Use (E-RCP) at 16.212, Marginal Lands (ML-RCP) at 16.214, and the Rural Residential zone at 16.290, which states that land in that zone is designated on the map as RR-1, RR-2, RR-5 or RR-10. The rural residential codes are stored here unhyphenated to match the statewide DLCD vocabulary; the county writes them with a hyphen. Two districts the chapter also carries — Natural Resource (NR-RCP) at 16.213 and Suburban Residential (RA-RCP) at 16.229 — are deliberately absent, because neither is a rural farm, forest or rural residential class this tool reasons about. Confirm the designation for a specific parcel with the county regardless: mapped boundaries are not a substitute for the county’s own determination.

Rural districts

Local district codes vary between counties. Each maps to a broader class that determines which pathways generally apply.

RR1

Rural Residential — RR-1 district

Rural residential

Land zoned to allow rural living on acreage. This is generally where a first dwelling is most likely to be achievable, and where second-dwelling options such as accessory dwellings or RVs are most likely to be available if the county permits them at all.

The suffix in this district's code is not a reliable guide to how much land is required. County code generally sets a two acre minimum for creating a new lot or parcel for residential purposes here, for as long as state commission rules require it, with a limited exception. An existing parcel may nonetheless be smaller than that. Confirm the actual size of the parcel and the current minimum with the county before relying on either.

RR2

Rural Residential — RR-2 district

Rural residential

Land zoned to allow rural living on acreage. This is generally where a first dwelling is most likely to be achievable, and where second-dwelling options such as accessory dwellings or RVs are most likely to be available if the county permits them at all.

Existing parcels may be smaller than the district's nominal acreage. Confirm the actual parcel size with the county.

RR5

Rural Residential — RR-5 district

Rural residential

Land zoned to allow rural living on acreage. This is generally where a first dwelling is most likely to be achievable, and where second-dwelling options such as accessory dwellings or RVs are most likely to be available if the county permits them at all.

Existing parcels may be smaller than the district's nominal acreage. Confirm the actual parcel size with the county.

E-RCP

Exclusive Farm Use

Exclusive farm use

Land zoned primarily to protect commercial agriculture. New dwellings are generally not allowed unless a narrow statutory test is met, and those tests are fact-intensive rather than automatic.

Lane Code 16.212. The use table splits almost every dwelling route by whether the land is High Value Farmland: a nonfarm dwelling on high value farmland and a nonfarm dwelling on non-high-value farmland are two separate provisions, each shown as prohibited on the other class. Which class a parcel falls in is therefore the first question rather than a detail.

F-1

Nonimpacted Forest Lands

Forest / conservation

Land zoned primarily to protect forest use and conservation values. New dwellings are generally not allowed except through narrow statutory tests, often with additional fire-related siting requirements.

Lane Code 16.210. The more restrictive of the two forest zones, and the difference matters: the F-1 use table lists no template dwelling, no lot of record dwelling and no large tract forest dwelling. Aside from a caretaker residence and a temporary hardship dwelling, the residential route listed is alteration, restoration or replacement of a lawfully established dwelling.

F-2

Impacted Forest Lands

Forest / conservation

Land zoned primarily to protect forest use and conservation values. New dwellings are generally not allowed except through narrow statutory tests, often with additional fire-related siting requirements.

Lane Code 16.211. Unlike F-1, the F-2 use table lists a template dwelling, a lot of record dwelling and a large tract forest dwelling alongside replacement of a lawfully established dwelling. The template test counts lots and dwellings that existed on 1 January 1993 inside a 160-acre square centred on the tract.

See pathways

ML-RCP

Marginal Lands

Mixed farm and forest

Land zoned for a mix of farm and forest use, typically in larger parcels. Dwelling approval is generally constrained and depends heavily on parcel history and the specific county's provisions.

Lane Code 16.214. Marginal Lands is a designation only two Oregon counties carry, applied to resource land that met neither the farm nor the forest productivity tests, and it is materially more permissive than either. The use table lists a dwelling on a vacant lot or parcel created before 1 July 1983 as permitted outright.

Pathways in this county

  • raw holdGenerally available

    Holding the land without placing a dwelling on it is generally available in every rural district. Under Oregon’s assessed value limit the tax base on unimproved land generally grows slowly until new construction occurs. Farm and forest land is also commonly under a special assessment that lowers the tax while the land stays in that use, and taking it out can trigger a deferred tax.

  • second dwelling rvAvailable with conditions

    The county adopted the state option allowing a recreational vehicle to be rented as a dwelling by Ordinance 25.01, effective February 27, 2025, at Lane Code 16.290(9), amended by Ordinance 25-07 in May 2026. One recreational vehicle used for residential purposes under a residential rental agreement is allowed on a rural residential lot or parcel that is not within an urban reserve, is developed with a lawfully established single-family dwelling occupied as the owner's primary residence, has no other dwelling units including a temporary medical hardship dwelling, has no part of the house rented as a tenancy, is not subject to an open code enforcement action, and — a condition the county added — is not within the regulatory floodplain defined in Lane Code 16.244. Before the use is established the owner records a covenant against vacation occupancy or other short-term use, the vehicle is owned or leased by the tenant, fully licensed and ready for highway use on its wheels or jacking system with quick-disconnect utilities and no permanent additions, a written rental agreement is in place, and the owner provides sewage disposal, water, electricity and any required drainage to a gravel, concrete or asphalt parking pad; the vehicle contains an operable toilet and sink or the owner provides them. The vehicle sits at least 10 feet from the house and other structures, at least 30 feet from land zoned F-1, F-2 or EFU, and any structure over it is open on at least two sides. County staff estimated that about 12,800 rural residential properties met the statute's minimum criteria and that roughly 790 of them lie entirely within the floodplain.

  • second dwelling aduAvailable with conditions

    This county adopted Ordinance 23-05 in August 2023, allowing accessory dwelling units on rural residential zoned property. County materials describe the parcel as generally needing to be at least two acres, with one single-family dwelling already on the property, and served by a fire protection service provider. State law generally limits the unit to 900 square feet and generally prohibits vacation rental use. Under state law a property generally may have either an accessory dwelling unit or a rented recreational vehicle, but not both.

  • primary dwellingAvailable with conditions

    Rural residential districts are generally the most likely rural districts to support a first dwelling, subject to the county's development standards, approved sanitation, legal access and applicable setbacks. Approval is still a county determination rather than an entitlement.

  • short term rentalNot yet researched

    This county's treatment of short-term rentals in unincorporated areas has not been researched here. Treat it as an open question rather than as permitted or prohibited. Note that this pathway presupposes a lawfully established dwelling to let — on bare land it generally becomes relevant only once a dwelling exists. Note separately that state law generally bars vacation occupancy of both a rural accessory dwelling unit and a rented recreational vehicle, so neither of those pathways can be combined with holiday letting regardless of the county's position.

  • temporary occupancy during constructionNot yet researched

    Counties commonly offer some form of temporary occupancy arrangement while a permitted dwelling is under construction, and neighbouring counties do. This county’s own provisions were looked for and not established, so this is recorded as an open question rather than as an available option. County materials found instead cover temporary dwellings for a documented medical hardship, which is a different arrangement.

  • primary dwellingAvailable with conditions

    Lane has two forest zones and they differ sharply, so which one a parcel is in is the first question. The Impacted Forest Lands zone (F-2) lists a template dwelling, a lot of record dwelling and a large tract forest dwelling in its use table, alongside replacement of a lawfully established dwelling. The Nonimpacted Forest Lands zone (F-1) lists none of those three — aside from a caretaker residence and a temporary hardship dwelling, its residential route is alteration, restoration or replacement of a lawfully established dwelling. Where the template route applies it counts lots and dwellings that existed on 1 January 1993 within a 160-acre square centred on the tract, so it turns on what surrounds a parcel rather than on the parcel itself.

  • primary dwellingAvailable with conditions

    The Exclusive Farm Use use table lists several dwelling routes rather than one: a primary farm dwelling, a relative farm help dwelling, an accessory farm dwelling for year-round or seasonal farm workers, a nonfarm dwelling, and alteration, restoration or replacement of a lawfully established dwelling. Nearly all of them are split by whether the land is High Value Farmland — a nonfarm dwelling on high value farmland and a nonfarm dwelling on non-high-value farmland are separate provisions, each shown as prohibited on the other class. Which class the parcel falls in therefore decides which routes are open before any of them is assessed.

  • primary dwellingAvailable with conditions

    Marginal Lands is a designation only two Oregon counties carry, applied to resource land that met neither the farm nor the forest productivity tests, and it is materially more permissive than either. The use table lists a dwelling on a vacant lot or parcel created before 1 July 1983 as permitted outright, and a dwelling on a vacant lot or parcel created under the county’s own Marginal Lands division provisions likewise. The question here is therefore when and how the parcel was created rather than what can be grown on it, which is a title question answerable from the deed chain.

  • non resource rezoneAvailable with conditions

    Changing a resource designation requires a plan amendment, which in Oregon generally means demonstrating that the land does not meet the definition of agricultural or forest land, or taking an exception to the relevant statewide planning goal. These are lengthy, expensive and contested proceedings decided on evidence rather than intention, and they are appealable to the Land Use Board of Appeals. Generally a sensible undertaking only for an existing owner.

  • second dwelling rvNot yet researched

    Lane has adopted the state option allowing a recreational vehicle to be rented as a dwelling, but that adoption is recorded here for rural residential zoned property. Whether the county extends it to farm, forest or marginal lands zoned property has not been established, and the resource zone use tables read for this entry do not list the use. Treat it as an open question in these districts rather than as available or unavailable.

  • temporary occupancy during constructionNot yet researched

    No provision expressly allowing occupancy of a recreational vehicle or temporary structure during construction was located in the resource zone use tables read for this entry. All four zones do list a temporary hardship dwelling, which is a different route with its own documentation requirements. Treat construction-period occupancy as an open question in these districts.

  • short term rentalNot yet researched

    This county’s treatment of short-term letting in resource zones has not been researched here. Treat it as an open question rather than as permitted or prohibited. The pathway also presupposes a lawfully established dwelling to let, which in these districts is itself the harder question.
