Subdividing Land in Camas County, Idaho

The clustering provision has a specific, size-based lot-yield schedule

Camas County's Subdivision Ordinance gives owners of qualifying agricultural land the option to cluster their dwelling units rather than spread them across the full parcel at the 80-acre base density. As reported in the county's subdivision ordinance materials, the eligibility threshold and yield are tied directly to how much contiguous land the owner starts with: an owner holding a quarter section (roughly 160 acres) is described as eligible for up to three clustered building lots; an owner holding a half section (roughly 320 acres) for up to six; and an owner holding a full section (roughly 640 acres) for up to twelve. Clustered lots themselves have to sit together on one contiguous piece of the parcel, with each lot no smaller than 1 acre and no larger than 10 acres.

That's a meaningfully different, more specific structure than "large-lot rural zoning" -- it's a documented formula, not a general policy of flexibility. If a listing for a larger Camas County agricultural tract advertises potential for several smaller building lots, this clustering schedule is almost certainly the mechanism being referenced, and the actual number of lots available depends directly on how much contiguous qualifying land is included in the calculation.

A real gap worth flagging: the lot-yield schedule doesn't obviously match the hub's 80-acre base density

Camas County's Agricultural zoning sets a base standard of one dwelling unit per 80 contiguous acres. Run straight through that ratio, a 160-acre quarter section would support two units, a 320-acre half section four, and a 640-acre full section eight. The clustering lot-yield schedule reported above -- three, six, and twelve lots for the same three parcel sizes -- doesn't line up with that math; it implies a denser ratio of roughly one unit per 53 acres instead. We were not able to independently reconcile this discrepancy from public sourcing, and it's possible the clustering provision uses a different base standard than the straight Agricultural-district density, was adopted or amended at a different time than the current base-density figure, or applies to a specific sub-area or version of the ordinance not fully captured in available public documents.

The practical takeaway for a buyer: don't do this math yourself and treat the result as final. Ask Camas County Planning and Zoning directly, in writing, exactly how many clustered lots a specific parcel of a specific size and location currently qualifies for under the current adopted Subdivision Ordinance -- and get the citation to the specific ordinance section they're relying on -- before valuing a parcel on the assumption of either the 80-acre base density or the lot-yield schedule described here.

It's a one-time option, not a repeatable subdivision tool

One clear, specific rule does emerge from the available sourcing: once a property has been run through the cluster-development calculation, it is no longer eligible for clustering consideration in the future. In other words, a landowner (or a chain of subsequent owners) can't keep re-clustering the same underlying acreage every time it changes hands or gets re-platted to generate additional lots beyond the original calculation. If you're buying a parcel specifically because of its clustering potential, confirm with the county whether that potential has already been used by a prior owner -- a parcel that looks like raw, unclustered acreage on paper may have already had its one cluster calculation consumed by an earlier transaction or plat.

Practical steps before relying on a specific subdivision outcome

1. Get written confirmation from Camas County Planning and Zoning of the current, adopted lot-yield schedule (and its relationship to the 80-acre base density) before assuming a specific number of buildable lots for a given parcel size.
2. Ask specifically whether the parcel you're evaluating, or any parent parcel it was split from, has already used its one-time cluster-development eligibility.
3. Request the current Subdivision Ordinance application checklist directly from the county rather than relying on a summary -- ordinance drafts and amendments referenced in county records span at least 2008, 2012, 2014, 2016, and 2019, so confirm you are working from the version currently in force.
4. If a real estate listing markets a parcel's cluster-subdivision potential, ask the seller or their agent for the specific county correspondence or approval documenting that potential, rather than taking the acreage-based math at face value.
