A fence seems simple, until it starts leaning, violates code, or creates tension with your neighbor. In Littleton, where soil shifts seasonally and local regulations carry real weight, small oversights can quickly turn into expensive repairs.
At MH Fence Co, we’ve seen it all. As a trusted fence company in Littleton, we work with homeowners every day who come to us after a fence has already started failing, or after a project went sideways because of something that could have been prevented in the first five minutes of planning.
The most common fencing mistakes include improper post installation, ignoring local regulations, building on the wrong property line, and choosing materials that aren’t built for Colorado’s freeze-thaw cycles. Many homeowners also underestimate post spacing requirements, skip permits, or fail to account for drainage and soil movement before breaking ground.
In Littleton specifically, clay-heavy soil expands and contracts with the seasons, and that movement will expose any weakness in a poorly set post. Another frequent mistake is prioritizing upfront savings over long-term durability, such as choosing untreated wood posts over steel-supported systems. The result is repairs within a few years instead of decades of reliable performance.
A well-built Littleton fence isn’t just about appearance. It’s about structural integrity, code compliance, and avoiding conflicts that could have been prevented with a little planning upfront.
What Are Common Fencing Mistakes to Avoid?
Here are the most frequent, and costly, missteps our team at MH Fence Co encounters on job sites across the area:
Skipping permits or HOA approval Most fences in Littleton require permits, particularly when height or placement is involved. Ignoring this step can lead to fines, delays, or even forced removal of a finished fence.
Incorrect post installation Shallow or improperly secured posts are the number one reason fences fail prematurely. In Colorado, frost heave can literally push posts upward if they aren’t set deep enough, and that’s a problem no homeowner wants to discover after winter.
Choosing the wrong material for the climate Not all wood or fencing materials perform equally under high-altitude sun and shifting soil. Choosing based on price alone often backfires within a season or two.
Improper spacing and layout Uneven panels and incorrect post spacing weaken the overall structure and affect the visual consistency of the finished fence. It’s one of those details that’s easy to get right, and equally easy to get wrong.
Building on the wrong boundary Even a few inches off can trigger legal disputes with neighbors. Verifying your property line before installation is a non-negotiable step that every reputable Littleton fence company will insist on.
Do You Have to Give Your Neighbor the Good Side of the Fence?
This is one of those questions that starts practical and quickly becomes personal.
In many areas, including Littleton, it’s considered standard practice, and sometimes required by HOA rules, to face the “good side” of the fence outward toward your neighbor or the street. The “good side” refers to the finished, smooth face without visible rails or structural posts showing through.
While it isn’t always a legal requirement, it’s a strong neighborhood norm that helps maintain curb appeal and prevents unnecessary friction. Many modern fence styles, like board-on-board or shadowbox designs, solve this entirely by presenting a finished look on both sides, which is often the smarter long-term investment.
When MH Fence Co consults with homeowners across Littleton, this is one of the first design conversations we have, because the right choice at the planning stage prevents a lot of awkward conversations down the road.
What Is the 1 3 Rule for Fence Posts?
The 1/3 rule is a straightforward but critical guideline for fence stability, and one of the most commonly ignored.
The rule is simple: at least one-third of every fence post should be buried underground. For a standard 6-foot fence, that means posts need to be set approximately 2 feet deep.
Why this matters in Littleton:
- Deeper posts resist wind load and lateral pressure
- They reduce movement caused by Littleton’s expanding clay soil
- They prevent shifting during the region’s freeze-thaw cycles
Cutting corners on post depth might save an hour of labor upfront, but it’s one of the fastest ways to end up with a leaning fence within a year or two. Every project completed by MH Fence Co follows this standard as a baseline, because proper depth is the foundation everything else depends on.
Who Owns Both Sides of a Fence?
Fence ownership can feel unclear, but it generally comes down to where the fence is physically placed relative to the property line.
- Fence fully inside your property line → You own it
- Fence sitting directly on the boundary → It may be shared responsibility
- Fence installed by a neighbor inside their property line → They own it
In Littleton, property surveys are essential. A significant number of neighbor disputes arise simply because boundaries were never clearly identified before installation began.
A practical approach: Before any work starts, confirm your property line and have a brief conversation with your neighbor. It takes 10 minutes and prevents years of friction. As one of the leading fence companies in Littleton, CO, MH Fence Co recommends this step to every homeowner, not because it’s legally required, but because it’s the right way to start a project.
Build It Right the First Time
Fencing mistakes are rarely dramatic. They’re small oversights, a post set two inches too shallow, a permit skipped, a property line assumed rather than confirmed, that compound quietly over time until the problem becomes impossible to ignore.
The good news is that every one of these mistakes is preventable with the right guidance and a team that knows Littleton’s soil, climate, and code requirements. If you’re planning a new fence in Littleton, MH Fence Co offers site evaluations that cover everything from property lines to soil conditions before a single post goes in the ground.
