Buying acreage in Elbert County comes down to answering three questions before you sign anything: where is your water coming from, where is your waste going, and what does the county allow you to do with the land. The number to remember is 35 acres, the threshold Colorado uses for well permits; below it, a well is typically limited to indoor household use only, per Colorado's Division of Water Resources. I have walked buyers through this in Kiowa, Bennett, Deer Trail, Strasburg, and Byers more times than I can count, and we live on acreage in Kiowa ourselves. This guide covers the permit and zoning side: what the state and county allow, which sign-offs you need, and what the paperwork should show. If you are a first-time buyer wondering what to inspect and budget for, start with my first-time buyer's guide to wells, septic, and easements.
- Confirm the parcel size before anything else. Under 35 acres usually means your well is limited to indoor use only, no yard, no livestock.
- Ask for septic (OWTS) permit records and confirm Elbert County Public Health signed off on the system.
- Find out if a percolation test has ever been run on the property, because it can determine whether you are allowed to build at all.
- Check the property's zoning district and minimum lot size before you plan a barn, guest house, or extra structure.
- Ask about groundwater trends in the area, especially if you are counting on that well for the next few decades.
What Does the 35-Acre Well Permit Rule Actually Mean for You?
Thirty-five acres is the magic number in Colorado water law, and it is worth memorizing before you tour a single property. According to Colorado Division of Water Resources deputy state engineer Sarah Brucker, wells on parcels smaller than 35 acres are likely limited to indoor use only (Colorado Public Radio, July 2025). That means no filling a stock tank, no watering more than a token patch of yard, nothing outside the house itself.
Get to 35 acres or more, and the same well permit can serve up to three single family homes, water up to an acre of lawn and garden, and supply your animals. That is a massive difference if you are picturing a horse pasture or a big vegetable garden.
There is also a separate category called an exempt well, limited to ordinary household purposes and fire protection, which sits outside Colorado's normal water rights priority system (Colorado Division of Water Resources, Guideline 2023-1). Ask which type of well permit is attached to a property before you assume anything about what you can do with the water.
Is Elbert County's Groundwater Supply Something to Watch?
Yes, and it is worth understanding before you commit to a well as your only water source for the next several decades. Roughly half of Elbert County's water use comes from groundwater pumped out of the Denver Basin aquifer system, which includes the upper Dawson, lower Dawson, Denver, Arapahoe, and Laramie-Fox Hills aquifers, according to a U.S. Geological Survey study done in cooperation with Elbert County (USGS, January 2026).
That same study tracked groundwater levels from 2015 through 2023 and found every one of those five aquifers trending downward, with median declines ranging from about a quarter foot per year in the upper Dawson to nearly two-thirds of a foot per year in the lower Dawson and Denver aquifers.
None of that means your well will run dry next year. It does mean asking a seller for well flow history and depth records is a smart move, not a paranoid one.
How Does Septic Permitting Work When You Buy or Sell Acreage Here?
Elbert County treats septic, officially called an OWTS or onsite wastewater treatment system, as its own permitting process separate from the county building department. Elbert County Public Health has to approve the septic installation before the building department will release a certificate of occupancy on new construction.
What Sellers Have to Do
At resale, the seller is required to get a use permit before the property can sell, and that requires an inspection from a licensed inspector in Elbert County to accompany the application. If you are buying an older acreage property, ask early whether that use permit and inspection have already happened. It can hold up closing if nobody starts the process in time.
What That Means for You as a Buyer
Do not assume a septic system that has worked fine for twenty years will sail through inspection. Get a copy of the actual inspection report, not just a verbal "it's fine," and build a little schedule cushion into your contract in case the system needs work before the use permit gets issued.
What Is a Percolation Test, and Why Does It Matter for Your Build Plans?
A percolation test, or perc test, measures how fast water drains through the soil on a property, and Elbert County's Board of Health uses that number to decide whether a lot can support a standard septic system or needs something bigger and more expensive.
Under the county's lot-size ordinance, a percolation rate slower than 45 minutes per inch, a slope over 5 percent, the need for subsurface drainage, or tricky topography can all trigger a requirement for a larger lot size before the county will approve septic capacity. In plain English, poor soil drainage can mean the county wants more land around that septic system, not less.
If a property does not already have a perc test on file, get one done before you get too attached to a specific building spot. It can change what you are allowed to build, and where.
Zoning and Lot-Size Rules Set What You Can Actually Do With the Land
Elbert County's zoning code sets minimum lot sizes and dimensional standards that vary by zoning district, and those standards affect everything from whether you can split a parcel to whether you can add a second structure. I am not going to hand you a single number here, because it genuinely depends on the zoning district your specific parcel sits in.
What I will tell you is to call the Elbert County planning department, or have your agent do it, before you assume anything about splitting land, adding an accessory building, or running a home-based business out on your acreage. It is a five-minute phone call that can save you months of frustration.
How Is Buying Acreage Different From a Standard Subdivision Purchase in Parker or Castle Rock?
If you have shopped for a house in Parker, Castle Rock, or Aurora, you are used to municipal water, municipal sewer, and an HOA that already told you exactly what you can and cannot do with your yard. Out here in Kiowa, Elizabeth, Agate, and the rest of Elbert County, and in Eastern Plains towns like Bennett, Deer Trail, Strasburg, and Byers just to the north, you are usually your own utility. Your well is your water department. Your septic system is your sewer district.
That is exactly why buyers come out here in the first place, more space, more say over your own land, and a slower pace than Denver traffic. It also means the due diligence list is longer, and skipping it costs a lot more than a bad HOA fee ever could.
What Should You Do Before You Write an Offer on Elbert County Acreage?
Think of it as a permit trail. Pull the well permit and confirm what type it is and what it actually allows. Ask for septic inspection and use permit records, or find out who is going to get them before closing. Find out if a perc test exists, and if it does not, get one scheduled. Call the county planning department about your specific zoning district before you plan any outbuildings.
None of this is meant to scare you off acreage. I love this part of the state, and I think a lot of people moving out from Denver, Aurora, and Colorado Springs are going to be happier out here once they know what they are actually walking into.
