How Much Does It Actually Cost to Develop Raw Land in Park County?
The number on the listing is just the starting point. What you spend after closing is where most buyers get surprised.
If you are looking at raw land in Park County, Montana, and thinking about what it would cost to build on it, the purchase price is only part of the equation. The bigger number, the one most buyers underestimate, is what it costs to turn a piece of dirt into a place you can actually live on.
This guide breaks down the real costs, line by line, based on what buyers in Paradise Valley, Livingston, and the surrounding corridors actually spend to develop raw land in 2026. No ranges pulled from national averages. Costs specific to this area, this geology, this climate.
The short answer: Developing raw land in Park County typically costs $75,000 to $200,000 or more before you break ground on a house, depending on distance from utilities, road access, soil conditions, and water depth. The biggest variables are well drilling, power line extension, and road construction. Budget at least $100,000 for site development on a property more than a quarter mile from existing infrastructure.
Legacy Lands Real Estate has helped buyers navigate these costs across Paradise Valley, Livingston, the Shields Valley, and south toward Gardiner for decades. What follows is what we tell every buyer considering raw land here.
What Does "Raw Land" Actually Mean in Park County?
Raw land means no well, no septic, no power, no improved road, and sometimes no legal access. In Park County, that describes a significant portion of the parcels available outside Livingston city limits.
The distinction matters because each missing piece of infrastructure has a real cost attached to it. A parcel with power at the property line and a county-maintained road is a completely different financial proposition than 40 acres at the end of a two-track in the Absarokas. Both might be listed as "raw land," but the development gap between them could be $150,000 or more.
Before you make an offer on any raw parcel, you need to price out every line item below. Not after closing. Before.
How Much Does It Cost to Drill a Well in Park County?
Well drilling is usually the first infrastructure question, and it is one of the hardest to predict. In Park County, a complete private well system typically costs between $10,000 and $30,000, with most residential wells landing in the $15,000 to $25,000 range.
The per-foot drilling cost runs $25 to $65 depending on geology. In the valley floor along the Yellowstone River corridor, wells often hit water at 40 to 80 feet. On the benches above the valley, expect 100 to 200 feet or deeper. Up in the side canyons like Mill Creek or Tom Miner Basin, depths vary wildly and hard rock drilling pushes costs toward the higher end.
Steel casing, required for deeper wells and certain soil conditions, costs roughly double what PVC casing does. Add the pump, pressure tank, electrical hookup, and water testing, and you are looking at the full range above.
One critical note for 2026: Montana's . You now need to file a Notice of Intent (Form 602I) with the before developing any new exempt well. The filing fee is $400, and DNRC has 10 business days to authorize or deny it. An exempt well can pump up to 35 gallons per minute and not exceed 10 acre-feet per year. If your intended use exceeds those limits, you need a full water rights permit, which is a longer and more expensive process.
Budget for a well: $15,000 to $25,000 for most Park County parcels, plus the $400 DNRC filing fee. Add $2,000 to $5,000 if you hit rock or need to go deeper than 150 feet.
What Does a Septic System Cost in Park County?
Every rural property in Park County needs a septic system. There is no public sewer outside Livingston city limits. In 2026, septic installation costs in the Livingston area range from roughly $10,000 to $30,000, with most conventional systems running $15,000 to $20,000.
The cost depends heavily on soil. A perc test (percolation test) determines how well your soil absorbs water, and that test dictates what type of system you need. Sandy, well-draining soil along the valley floor often allows a conventional gravity system, the cheapest option. Clay-heavy soils on the benches or in side valleys may require an engineered system, a mound system, or a sand filter system, each of which costs more.
The reviews all septic applications. The review fee runs about $675 per subdivision, plus additional fees depending on the configuration. You will also need a site evaluation, which typically costs $500 to $1,000 from a licensed soil scientist or engineer.
| System Type | Typical Cost | When Required |
|---|---|---|
| Conventional gravity | $10,000 to $15,000 | Good soil drainage, adequate setbacks |
| Pressure distribution | $15,000 to $22,000 | Moderate soil, larger drain field needed |
| Mound system | $20,000 to $30,000 | Poor soil drainage, high water table |
| Sand filter | $18,000 to $28,000 | Shallow bedrock, environmental sensitivity |
Budget for septic: $15,000 to $25,000 for most parcels, including the perc test, design, permitting, and installation. Get the soil tested before you close on the property, not after.
How Much Does It Cost to Run Power to a Rural Parcel?
Power line extension is where costs can escalate fast, especially on remote parcels. NorthWestern Energy serves most of Park County, and the cost to extend power depends almost entirely on distance from the nearest existing line.
Overhead power line installation runs $5 to $15 per linear foot. Underground lines cost $10 to $25 per foot. Each utility pole costs $1,200 to $5,600 to install, and in rural stretches, poles are spaced roughly every 300 feet.
Some quick math: if the nearest power line is a quarter mile (1,320 feet) from your building site, an overhead extension could run $7,000 to $20,000. At half a mile, you are looking at $15,000 to $40,000. At a full mile, costs can exceed $50,000.
provides the first cost estimate free of charge, and they will assess your specific run before you commit. Request this estimate during your due diligence period, not after closing.
The alternative is off-grid solar, which has come down in cost but requires a battery system, backup generator, and careful load planning. A complete off-grid solar setup for a modest home in this climate runs $25,000 to $60,000, and you need to account for Montana's short winter days and heavy snow loads on panels.
Budget for power: $10,000 to $50,000 for grid connection depending on distance, or $25,000 to $60,000 for a complete off-grid solar system.
What Does Road Access Cost to Build or Improve?
Road access is the cost most buyers fail to research. If your parcel does not have direct access from a county-maintained road, you need to build or improve a private road, and that gets expensive quickly.
A basic gravel driveway or access road in Park County runs $15 to $25 per linear foot for grading, gravel base, and drainage. For a quarter-mile access road (1,320 feet), that is $20,000 to $33,000. A longer run, say half a mile through sloped or timbered terrain, can reach $40,000 to $75,000 once you factor in culverts, drainage ditches, and grade work.
If you need to cross a creek or drainage, add $5,000 to $20,000 for a proper culvert or low-water crossing. If the county requires a specific road standard for fire access or school bus routes, costs go up further.
One thing buyers often miss: legal access is different from physical access. A two-track that crosses your neighbor's land is not legal access unless you have a recorded easement. Verify legal access with a title search and survey before you commit to the purchase.
Budget for road access: $20,000 to $75,000 for a private access road, depending on length, terrain, and drainage requirements. Budget $0 if the parcel fronts a county road.
What Are the Other Costs Most Buyers Forget?
Beyond the big four (well, septic, power, road), several smaller costs add up. Most buyers budget for the major items but miss these:
Land survey: A boundary survey in Montana runs $800 to $5,500 depending on acreage and terrain. For a 20-acre parcel with clear corners, expect $1,500 to $3,000. For larger or heavily wooded parcels, costs climb. Schedule surveys during the off-season (November through February) to potentially save 20-30%.
Site grading and excavation: Preparing a building pad, driveway cuts, and drainage on a sloped site runs $5,000 to $15,000 in this area.
Permits and fees: include zoning compliance permits at $300, floodplain permits at $300, and various review fees. Montana building permits through the typically run $1,500 to $5,000 depending on the project scope.
Soil and environmental testing: Beyond the perc test, you may need radon testing, environmental assessments, or geotechnical reports. Budget $1,000 to $3,000 for the full battery.
Fire mitigation: Many areas in Park County fall within the wildland-urban interface. Your insurance company may require defensible space clearing, which runs $2,000 to $8,000 depending on timber density.
What Does the Total Development Budget Actually Look Like?
Here is a realistic range for developing a raw parcel in Park County into a buildable site, before you start construction on a house:
| Item | Low Estimate | High Estimate |
|---|---|---|
| Well drilling and completion | $15,000 | $30,000 |
| Septic system | $10,000 | $30,000 |
| Power extension (0.25 mile) | $10,000 | $25,000 |
| Road access (0.25 mile) | $20,000 | $35,000 |
| Land survey | $1,500 | $3,500 |
| Site grading | $5,000 | $15,000 |
| Permits and fees | $2,500 | $6,000 |
| Testing and assessments | $1,000 | $3,000 |
| Fire mitigation | $2,000 | $8,000 |
| Total site development | $67,000 | $155,500 |
That is the cost to get a basic raw parcel to the point where a builder can start framing a house. The house itself, at current Montana construction costs of $200 to $400 per square foot in the Gallatin and Park County corridor, is a separate line item entirely.
A 2,000-square-foot home on a developed site in Park County is running $400,000 to $700,000 in construction costs alone in 2026. Add that to the site development costs above and the purchase price of the land, and you have the real number. Of course, all of this depends on the scope of the work, the topograpy, etc.. Our goal is just to give you a rough idea buit researching these costs yourself is your best bet.
What Tradeoffs Should You Think About Before Buying Raw Land?
Raw land in Park County is not a bad investment. It is a different investment than most buyers initially calculate.
The tradeoff is real: raw land is cheaper per acre than improved parcels, sometimes dramatically so. A 20-acre raw parcel might list at $150,000, while a comparable 20 acres with well, septic, power, and road access lists at $300,000 or more. The question is whether you save money by developing it yourself or whether you are just deferring (and sometimes multiplying) the costs.
Factors that tip the math in favor of buying raw:
You want a specific location that only exists as raw land
You have the time to manage the development process (12 to 18 months is typical)
You can phase the development to spread costs over multiple building seasons
You are comfortable managing contractors in a rural market where good ones are booked 6 to 12 months out
Factors that tip the math against raw:
You need to build and move in quickly
The parcel is more than half a mile from utilities
Soil conditions are unknown or marginal
Legal access is unclear or requires easement negotiation
Next Steps
If you are considering raw land in Park County, do three things before making an offer:
Get a development cost estimate first. Walk the property with a builder or site developer who knows this area. Get real numbers on well depth, power distance, and road requirements before you write a check.
Talk to the county. can tell you about zoning restrictions, floodplain issues, and any pending subdivision or development regulations that affect your parcel.
Call a broker who knows the land. Not every piece of raw land in Park County is worth developing. Some parcels have issues that make development impractical or prohibitively expensive. A broker who has walked the property and knows the area can save you from a costly mistake.

Frequently Asked Questions
How much does it cost to develop raw land in Park County, Montana?
Total site development costs for raw land in Park County typically range from $67,000 to $155,000 or more, covering well drilling, septic installation, power extension, road access, surveying, grading, permits, and testing. The exact cost depends on distance from utilities, soil conditions, water depth, and terrain.
Do I need a permit to drill a well on my property in Montana?
As of January 1, 2026, you must file a Notice of Intent with the Montana DNRC before developing any new exempt well. The filing fee is $400. An exempt well can pump up to 35 gallons per minute and not exceed 10 acre-feet per year. Wells exceeding those limits require a full water rights permit.
How deep are wells in Paradise Valley?
Well depth in Paradise Valley varies significantly by location. Along the valley floor near the Yellowstone River, wells often reach water at 40 to 80 feet. On the benches above the valley, expect 100 to 200 feet or deeper. Side canyons like Mill Creek and Tom Miner Basin can vary widely.
What type of septic system do I need in Park County?
The type of septic system depends on your soil. A perc test determines drainage capacity. Well-draining soil allows a conventional gravity system ($10,000 to $15,000). Poor soil may require a mound system ($20,000 to $30,000) or sand filter ($18,000 to $28,000). The Park County Sanitarian reviews all applications.
Can I live off-grid on raw land in Park County?
Yes, off-grid living is legal in Park County. A complete off-grid solar system for a modest home runs $25,000 to $60,000, including batteries and a backup generator. You will still need a well and septic system. Account for Montana's short winter days and heavy snow loads when sizing a solar array.
How long does it take to develop raw land in Park County?
Plan for 12 to 18 months from purchase to a buildable site, assuming no major permitting delays. Well drilling, septic permitting, and power extension each have lead times, and good contractors in this market are often booked 6 to 12 months out. Winter weather limits the building season to roughly May through October.
Is raw land cheaper than improved parcels in Park County?
Raw land is typically 30-50% cheaper per acre than comparable improved parcels. However, once you add development costs ($67,000 to $155,000), the total investment often approaches or exceeds the price of an already-improved parcel. The math depends on distance from utilities and soil conditions.
What should I check before buying raw land in Montana?
Before making an offer, verify legal access (recorded easement or county road frontage), check well depth in the area, get a perc test for septic feasibility, confirm distance to the nearest power line, review zoning and floodplain status with Park County Planning, and request a development cost estimate from a local builder.
