ILC vs. Boundary Survey: Which One Do You Actually Need for Land Surveying in Rifle CO?
Choosing the right survey type in Colorado can save property owners time, money, and legal headaches. Whether you are closing on a home, planning a fence build, or pulling a new construction permit in the Rifle, CO, area, understanding which document you actually need matters. As the land surveying professionals property owners depend on, we can help clarify requirements before a project begins. The two survey types look similar on the surface, but they serve very different legal purposes under Colorado law.
What Is an ILC in Colorado?
An ILC, or Improvement Location Certificate, shows where existing structures sit on a property. We certify, based on a visual inspection and existing records, where improvements such as the house, garage, fences, and driveway appear to sit relative to the property's boundaries and any easements. It answers one basic question: does anything look obviously wrong?
The document is governed by Colorado Revised Statutes section 38-51-108, which requires that it be prominently labeled as an improvement location certificate and carry a disclaimer stating it is not a land survey plat or improvement survey plat, and that it is not to be relied upon for the establishment of fence, building, or other future improvement lines.
Lenders and title companies most commonly request an ILC at closing during the transfer of title. ILCs can often be completed faster than a full boundary survey, making them practical for straightforward residential transactions. Consulting our land surveying team early can prevent delays at closing.
What Is a Boundary Survey in Colorado?
A boundary survey legally establishes where a property's lines actually are. It identifies and monuments corners, reviews title documents and easements, and produces a certified map that carries legal weight an ILC cannot.
As professional land surveyors, we review the current legal description, deed information of adjoining properties, and make a thorough effort to recover monuments in the field, including public land monuments such as section corners and quarter corners. Courts and title insurers rely on a full survey when boundary certainty is needed. If a dispute arises, an ILC will not settle it.
When Does Each Survey Type Apply in Garfield County?
The right survey type depends on your project goal. Garfield County and the City of Rifle have specific documentation requirements tied to land use change permits, building permits, and subdivision platting.
Real estate closing: When a homebuyer requests Owner's Extended Coverage title insurance, the title company orders what is commonly called "the survey," which is actually an ILC. An ILC is usually sufficient for a standard residential closing in Garfield County.
Building a fence or adding a structure: You need a land survey plat to confirm your property line. An ILC does not set or verify property corners, and the certificate itself states it cannot be relied on to build a fence or locate exact lines. On rural parcels near Rifle where lot lines may not be obvious from the ground, this distinction matters even more.
New construction and Garfield County permits: Any structure built within a certain distance of a property line and not within a previously surveyed building envelope shall have a licensed surveyor's signature and professional stamp on the drawing. In those cases, an ILC is generally not enough. Our
land surveying team can prepare the stamped documentation Garfield County requires.
Boundary disputes or title issues: A true survey such as an improvement survey plat or land survey plat is required to clarify discrepancies. Properties along the Colorado River corridor near Rifle can carry complex title histories, making a full boundary survey the safer choice for rural acreage transactions.
Three Frequently Asked Questions
Can an ILC Be Used to Install a Fence in Colorado?
No. Under Colorado law, an ILC carries a mandatory disclaimer stating it cannot be relied upon for fence lines or future improvement lines. It does not locate exact boundaries, does not establish property corners, and is not to be legally relied upon for locations of property lines or future improvements. A land survey plat is required when placing a fence on or near a property line.
Does Garfield County Require a Boundary Survey for a Building Permit?
It depends on the project. Garfield County's building checklist requires site plans to show all property lines, building envelopes, and setback distances from boundaries. For structures located outside a recorded building envelope, a licensed surveyor's stamp on the site plan drawing may be required. Confirm requirements directly with Garfield County Community Development before submitting.
Which Survey Type Is Right for a Rural Acreage Purchase Near Rifle, CO?
For rural parcels, a boundary survey often provides stronger protection. The cost gap between an ILC and a full survey on rural land narrows considerably. When a parcel has an irregular legal description, access easements, or sits adjacent to Bureau of Land Management or U.S. Forest Service land, a full boundary survey is the more prudent investment. As experienced land surveying professionals, we can evaluate your parcel and recommend the appropriate document before you commit to a purchase.
Get the Right Survey for Your Rifle Area Project
Choosing between an ILC and a boundary survey comes down to what you need the document to do. An ILC works well for a standard home purchase closing. A boundary survey is the right call for fence placement, new construction outside a recorded building envelope, resolving a title dispute, or purchasing rural acreage with complex legal descriptions.
