Selling vacant land in Valley County, Idaho: complete 2026 guide

01The Valley County land market in 2026

Valley County covers 3,733 square miles (3,665 land, 68 water) in west-central Idaho, ranking fifth-largest by area. The 2020 census put population at 11,746 across three incorporated cities: Cascade (county seat), Donnelly, and McCall (the largest). The county is named after the Long Valley of the North Fork of the Payette River.

The vacant land market splits into four practical sub-markets:

• McCall and Payette Lake. The dominant market. McCall sits at 5,030 feet on the southern shore of Payette Lake (4,986.7 acres, max depth 304 feet). Buyers are out-of-state second-home buyers and retirees. Waterfront and near-water lots carry a premium that does not appear on the assessor roll.
• Donnelly, Lake Cascade north shore, and Tamarack. Lake Cascade is 47 sq mi, the fourth-largest reservoir in Idaho, completed by the Bureau of Reclamation in 1948. Donnelly is the closest incorporated town to Tamarack Resort on the west shore. Lake recreation at lower entry than McCall.
• Cascade and the south end. Lower per-acre prices, larger parcels, more agricultural and recreational use. Working buyers, hunters, retirees, occasional ranch operators.
• Back-country and federal-edge parcels. Pistol Creek, Trails End, Yellow Pine, Warm Lake. Limited road access (sometimes seasonal only), tighter mortgage availability, lower comparables. Recreational, often cash.

Per LandSearch, there are roughly 222 undeveloped land listings countywide averaging $539,081 list and $50,411 per acre. McCall-area listings (165 of them) average roughly $157,465 per acre. The ~3x gap is the McCall premium in one number.

For the broader improved-property market, Redfin's September 2025 McCall data showed median home sale prices at roughly $617,000, with homes selling in approximately 103 days on market at about 4 percent below list. Improved residential is leading vacant land down off the 2022 peak.

02Zoning, lot size, and the septic-driven minimums

Valley County's land use code lives at Title 9 (Land Use and Development) of the Valley County Code, with subdivision-specific provisions at Title 9, Chapter 12, and zoning classifications referenced at section 9-12-3. The county uses a performance-based approach rather than the dense district-by-district matrix common in Idaho's bigger counties.

The practical minimum lot sizes used by Valley County Planning and Zoning are tied directly to water and sewage infrastructure:

If your parcel sits inside an HOA or improvement district running central water and sewer (Tamarack Village, some McCall-area subdivisions, parts of Donnelly), it can be much smaller than the one-acre baseline. Out in the woods on well and drainfield, the 1-acre floor controls. Cities (McCall, Donnelly, Cascade) have their own zoning codes and are separate jurisdictions; McCall has a more conventional district map plus a McCall Municipal Airport Influence Overlay covered later.

03Water rights: Snake River Basin Adjudication

Idaho's water-rights universe was reset by the Snake River Basin Adjudication (SRBA), the legal inventory of roughly 150,000 water rights across the Snake River basin and its tributaries, covering 38 of Idaho's 44 counties. The Final Unified Decree was signed on August 25, 2014, by the Fifth Judicial District Court in Twin Falls and issued more than 158,000 partial decrees in the process. The decree is conclusive as to the nature and extent of water rights with a priority date prior to November 19, 1987.

Valley County is geographically split: most of the populated valley (McCall, Donnelly, Cascade, Tamarack, Brundage) sits in the Payette River drainage, which feeds the Snake and was therefore inside the SRBA. The northeastern back-country (Yellow Pine area and beyond) drains to the Salmon River, which is a separate basin. Pull the Idaho Department of Water Resources water-right report for any parcel that claims irrigation, stockwater, or other beneficial use before listing.

Practical implications: a decreed senior-priority right (especially pre-1900) is a tradable asset and should be priced and disclosed up front; junior or deferred stockwater/domestic claims may not be fully decreed and can be challenged in dry years (do not advertise unsourced "water rights"); domestic-only use without a right is allowed if the parcel meets Idaho's domestic-purpose exemption (confirm with IDWR).

04Idaho homeowner exemption and circuit breaker

Idaho has no Oregon-style Measure 50, no California Prop 13, and no Washington 1-percent levy cap built around assessed-value freezes. Idaho's main residential property-tax relief is the homeowner's exemption under Idaho Code 63-602G. It exempts 50 percent of the value of your home and up to one acre of land, capped at $125,000. The cap was set in 2021 and stays at that level unless the legislature changes it.

The exemption requires owner-occupied primary residence on or before the last business day of December, with an application filed by that day. Vacant land with no qualifying dwelling does not qualify; neither do second homes or rentals.

Idaho also runs the property tax reduction program (the "circuit breaker"). Per the Idaho State Tax Commission's 2026 brochure, qualifying owners with 2025 income at or below $39,130 (after deductible medical) may reduce property taxes on the home and one acre by up to $1,500. Eligibility requires age 65+, blindness, disability, widow/widower status, former POW/hostage, or motherless/fatherless child under 18.

05Price ranges by sub-market

These are 2024 to early 2026 ballpark ranges synthesized from LandSearch, Redfin, and recent comps. Specific parcels move on lake frontage, ski access, road quality, water rights, septic feasibility, and HOA status.

If a cash offer prices your parcel materially below the bottom of the band for your sub-market, you have a wholesale assignment offer, not a market offer.

06Who actually buys Valley County land

Five buyer pools are active in Valley County in 2026:

• Out-of-state second-home and retirement buyers (historically CA, WA, UT, TX) drove the 2021-22 spike; smaller in 2026 but still the dominant retail buyer for McCall.
• Boise-area weekend-home buyers on the 100-mile Highway 55 commute, less price-sensitive after Treasure Valley appreciation.
• Ski-resort buyers at Brundage Northwoods/Norhaven and Tamarack Village, buying lifestyle product, not raw land.
• Recreational and hunting buyers on larger back-country parcels south and east of Cascade. Cash-heavy.
• Land flippers and wholesalers contracting parcels at 40 to 60 percent of fair value for assignment. This pool generated the cash offer in most landowners' mailboxes.

07Wholesale vs retail vs developer math

The cash offer in your mail is not the same animal as the price a McCall realtor would list your parcel at. Wholesale buyers sign assignable contracts and price for discount that absorbs closing, holding, marketing, and assignment fee, typically landing at 40 to 60 percent of fair retail. Retail buyers keep the land, pay cash or use a recreational-land loan, take six months, and pay 90 to 100 percent of fair retail (sometimes higher on Payette Lake waterfront and Brundage ski lots). Developer offers are almost nonexistent on raw rural Valley County land because the 1-acre well/septic minimum and lack of central services make conventional residential subdivision uneconomic; developers do show up for in-town McCall infill and master-planned ski/lake communities.

Translation: if your parcel is raw acreage outside an HOA and your only competing offers are mail-based cash buyers, the bidder universe is wholesalers competing for the same discount.

08Septic, wells, and Central District Health

Outside city limits and HOA central systems, you need both a well and an on-site septic system. Septic permitting in Valley County runs through Central District Health (CDH), which covers Ada, Boise, Elmore, and Valley counties under Idaho's Individual/Subsurface Sewage Disposal Rules (IDAPA 58.01.03). The Valley County CDH office sits at 703 1st St., McCall, ID 83638, 208-634-7194.

Practical steps when listing a parcel that needs new septic: order a CDH site evaluation (to-scale plot plan showing dwelling, well, primary septic, and replacement drainfield); get perc data, because failed perc, high water table, shallow bedrock, or steep slope can force a sand-mound or other advanced system at triple the cost (or kill buildability outright); confirm setbacks near Payette Lake, Lake Cascade, the Payette River, the Salmon River, and known seasonal high water; and disclose results in the listing (a "buildable lot" with no feasibility study is not the same as a CDH-approved 4-bedroom standard site).

Wells in the McCall area are typically 100 to 400 feet deep on the bench lands. Lakeshore and valley-floor lots can hit water shallower; back-country granite parcels can run much deeper. Get a local driller quote and disclose nearby known dry holes.

09Tamarack Resort and what its HOA means

Tamarack Resort, on the west shore of Lake Cascade roughly 90 miles north of Boise near Donnelly, is the largest single development in Valley County and has a complex ownership history that still affects per-lot pricing. The majority owners filed for Chapter 11 bankruptcy on February 20, 2008, after defaulting on a $260 million Credit Suisse loan. The resort closed, then reopened skiing on December 20, 2010, under the homeowner-formed Tamarack Municipal Association (TMA). Credit Suisse acquired most assets at a sheriff's sale on March 10, 2014. Tamarack Resort Holdings (Imperium Blue) closed its acquisition on November 30, 2018. In October 2021, MMG Equity Partners took full control.

If you own a Tamarack lot in 2026, two things matter for a sale. First, the TMA assessment funds infrastructure, services, and a portion of the ski operation; get a current statement and disclose it. Second, the development trajectory has gone from "ghost town" to active construction over the last several years, with completed lifts, restaurants, and a bike park that did not exist five years ago, which means 2019-2021 comparable sales underprice 2026 product.

10Brundage Mountain and the slopeside neighborhoods

Brundage Mountain, eight miles north of McCall, was acquired by Brundage Mountain Holdings (an Idaho family group) in November 2020. Since 2021, the resort has reinvested roughly $35 million from residential development into ski-area improvements, including the high-speed Centennial Express chairlift (winter 2023-24) and the new Mountain Adventure Center (winter 2024-25). The mountain averages 320+ inches of snow per year with a 1,921-foot vertical drop.

Two slopeside neighborhoods drive most of the new land activity: Northwoods, Brundage's first ski-in/ski-out neighborhood with 32 lots on Lower Rodeo (development began 2022); and Norhaven, the second slopeside community with 39 planned units (ground broke 2025). If you own a Brundage-area parcel outside these master-planned neighborhoods, the ski-area momentum is a tailwind, but raw "near Brundage" land does not automatically clear $400K to $1M+ per lot like Northwoods/Norhaven product. Comps must be inside the same access and amenity envelope.

11Federal land, USFS checkerboard, and access

Valley County is largely federal. The Payette National Forest alone covers roughly 2.3 million acres across Valley, Idaho, Adams, and Washington counties, with headquarters in McCall and five ranger districts (McCall, Krassel, New Meadows, Council, Weiser). Parts of the Boise National Forest and Salmon-Challis National Forest also sit inside Valley County. About 790,000 acres of the Payette is inside the Frank Church-River of No Return Wilderness, the largest contiguous wilderness in the lower 48.

Practical implications: access often crosses federal land, so confirm whether your access route is a county road, state road, recorded easement, or a USFS road open year-round (seasonal closures are common in winter). Adjacency to federal land is mostly a benefit because the un-developable backdrop is a buyer feature, with wildfire risk as the trade-off. Full inholdings inside the Payette with no neighbors on three or four sides sell at a discount because access, services, and resale liquidity are all harder. Idaho Department of Lands endowment lands also surround Payette and Little Payette lakes, and pending IDL/USFS exchanges can affect long-term value.

12Snow load, building code, and McCall airport overlay

Per Valley County Code section 6-1-8, the design snow load across most of the county runs 120 to 150 psf depending on location, based on the 1986 University of Idaho snow load study and the Valley County snow load zone map. The Pistol Creek and Trails End back-country areas use a lower 60 psf live load. Commercial, public-use, and assembly buildings must be designed for the basic design snow load with stamped plans from an Idaho-licensed architect or engineer.

This matters for raw-land pricing in two ways: build cost in Valley County is materially higher per square foot than the same build in Boise because of the structural load; and parcels already site-graded with engineered cuts, fills, and known foundation conditions sell at a premium because the buyer has fewer surprises.

For parcels in or near the City of McCall, the McCall Municipal Airport Influence Overlay (Section 3.7.05, McCall City Code) imposes additional restrictions on uses, structure heights, and light/glare in the approach and noise-impact zones around McCall Municipal Airport (KMYL). The airport sits at 5,021 feet elevation and includes a U.S. Forest Service Smokejumper Base. If your parcel sits inside the overlay, it governs in addition to the underlying zoning.

13Wildfire, the 2024 fire season, and insurance

Wildfire is a permanent feature of Valley County land, not a once-in-a-decade event. The 2024 fire season alone produced the West Mountain Complex on the Payette National Forest, including:

• The Snag Fire, 11 miles east of Cascade, burning roughly 25,235 acres by late August 2024.
• The Wolf Creek Fire, 5 miles west of Donnelly, at 1,154 acres.
• The Dollar Fire, 18 miles northeast of Cascade, at 1,865 acres.
• The Lava Fire on the Boise and Payette National Forests north of Emmett and west of Lake Cascade, growing to roughly 97,844 acres by September 20, 2024, all lightning-started.

None of those fires hit the McCall corridor directly, but smoke impact and insurance posture both move on regional fire activity. Several national carriers have pulled back from high-risk Idaho ZIPs, and buyers may need to shop carriers or use non-standard policies; disclose any prior non-renewals on the existing structure. FireWise USA community certification carries better insurance availability and faster mortgage approval. Defensible-space zones (typically 30, 100, and 200 feet around any structure) should be cleared to standard before listing if you clear the lot at all.

14School districts and what they signal

Valley County has two school districts. McCall-Donnelly Joint School District 421 serves McCall, Donnelly, and the northern half of the county, with total enrollment around 1,189 students. Cascade School District 422 serves Cascade and the south end, with combined elementary and junior-senior high enrollment of about 260 students.

For a vacant-land seller, the district line is real money. Out-of-state buyers shopping for a primary or extended-stay home in Valley County typically default to McCall-Donnelly because the schools are larger and rated higher on common comparison sites. Cascade District serves a smaller, more local market. Confirm which district your parcel sits in by APN before listing because some Donnelly-area parcels fall into Cascade and some Cascade-area parcels fall into McCall-Donnelly.

15Timeline, listing, and the cleanest path to close

A clean Valley County land sale typically runs three to six months in McCall and Donnelly, and four to nine months in Cascade and back-country areas, from list to close at retail. A wholesale cash sale can close in 14 to 30 days at 40 to 50 percent of value. Accelerators that move a retail listing closer to the fast end: clean title (no open mortgages, judgment liens, lis pendens, or unreleased deeds of trust); current property tax balance; HOA payoff letter from the relevant association (Tamarack Municipal Association, Brundage Northwoods, McCall lake-area HOAs); well log or a clear statement that no well exists; CDH septic feasibility already on file; recorded plat and a clear statement of legal access; and an IDWR water-right report if any beneficial use is claimed.

This is the package a DirtIQ Complete report pulls together in one document. The cleaner the package, the shorter the diligence on the buyer side, the less rope a contingent buyer has to walk.

16The five mistakes that destroy value

1. Accepting the first cash offer without comping the sub-market. The mail offer is priced for the wholesaler's margin, not your number. A 30-minute pull of recent LandSearch or LandWatch comps for your specific town and acreage band usually shows the spread.
2. Mispricing the access. A "10-minute drive from McCall" parcel on a privately maintained dirt road is not the same as a "10-minute drive from McCall" parcel on a paved county road. Plowed-in-winter, year-round, recorded-easement access is a price multiplier.
3. Failing to disclose septic status. An un-perc'd parcel listed as "buildable" creates buyer mistrust and renegotiation. Pull the CDH feasibility before listing or price the parcel as a "needs feasibility" speculative lot.
4. Ignoring HOA mechanics in Tamarack and Brundage areas. Outstanding TMA or association assessments transfer with title. Resolve and document before listing.
5. Listing in October. Valley County's selling season runs roughly May through September. Winter listings sit. If you have a choice, list in spring.
