Easements That Block Construction: Lines, Pipes, Access
A restrictive easement can seal off the building envelope or kill a project late. See the easement types that most often block construction and how to spot them early.
When a project collapses late, it is rarely the building rights that fail. The local plan has been read, the plot ratio penciled in, the municipality is positive. What topples the project is often a registered easement nobody took seriously: a building line running through the only viable building zone, a pipe corridor beneath the planned house, an access right the neighbour suddenly refuses to grant. They do not appear in the local plan, but they bind the property just as tightly — and they do not live in a tidy folder, they live in tingbogen (the Land Registry).
An easement that restricts construction is a private-law or public-law burden that limits what you may do with the site. It runs with the property, not the owner, and it does not disappear when ownership changes hands. The difference between a project that lands and one that runs aground is often simply when the burden gets discovered — in the due diligence phase, where it can be priced in or negotiated away, or after the deed is signed, where it is yours.
What a restrictive easement actually does
A restrictive easement does not remove ownership, but it removes freedom to use the land. It can prohibit building within a particular zone, limit building height, require a specific distance to the boundary, protect a neighbour’s view, or reserve an area for a pipe or a road. It is typically negative — it tells you what you may not do — and it binds any later purchaser by virtue of being registered.
The crucial point is that easements operate independently of the public-law planning framework. A local plan may permit a detached single-family house in two storeys, and an easement from the 1940s may nonetheless forbid building above one storey on precisely the part of the site where the house is meant to stand. Both apply. You must comply with the stricter one. When you want to understand building rights on paper, you read the plan — but how to read a local plan correctly settles only one half; the easements settle the other.
Rule of thumb: the local plan says what you may build in theory. The easements say what you can actually build on this site. The rules stack — the strictest wins.
The three easement types that most often block construction
Building lines
A building line defines an area where no construction may be erected — typically to safeguard future road widening, sight lines at an intersection, a setback from a watercourse, or a high-voltage line. It can be registered as a private easement or imposed under public law, for example via road legislation.
The danger with building lines is geometric. On a large site you simply move the building zone; on a narrow or shallow site a building line can consume the entire area where a house could realistically sit. Two building lines from two sides can together leave a building zone too small for the project — without either one looking dramatic on its own. Always plot the building lines onto the cadastral map before you start calculating floor area.
Pipe corridors
A pipe corridor is an area reserved for a utility or sewer line, often with a covenant that forbids building and deep-rooted planting over the line, and that secures the line owner access for operation and repair. Water, wastewater, district heating, electricity, gas, and fibre can all have registered corridors.
A pipe easement rarely kills a project outright, but it dictates placement. You generally may not build on top of the corridor, and relocating the line is possible but requires the line owner’s consent and can cost considerably — both in works and in time. Find the corridor before you fix the position of the house, not after.
Access rights and right-of-way easements
A right-of-way gives another property the right to pass over your site — or gives your site the right to pass over the neighbour’s. On back-lying sites with no direct access to a public road, the right-of-way is often the only lawful access, and it is a precondition for the municipality even approving construction. If the right-of-way is unclear, limited to “agricultural use”, or registered solely in favour of one particular use, an intensification — say from one house to several dwellings — may fall outside what the right-of-way covers.
Here you must read the wording closely: who holds the right, for what purpose, and is there a limit on traffic volume? A right-of-way that suits a single-family house will not necessarily hold up for a terraced-housing project.
Where they hide — and why they get overlooked
All three types live in tingbogen (the Land Registry), but they are not always easy to read. The easements section can hold references to old documents that exist only as scanned covenants from before digital land registration. A line such as “Document on building lines etc.” does not itself reveal whether the building line hits your building zone — you have to retrieve and read the underlying document. Understanding how a land registry certificate is built up with title, encumbrances, and burdens is the precondition for even tracing your way to the right documents.
The usual reasons burdens get overlooked:
- The easement is old and vaguely worded. A covenant from the 1930s may describe the building zone by reference to a missing appendix, or use measurements that cannot readily be transferred to today’s cadastre.
- It is not in the local plan. Many confuse “planning status” with “all constraints”. Plandata.dk (the public planning data portal) covers the public-law planning framework — not the private-law easements.
- It looks harmless. A sight-line easement or a height restriction seems innocuous until it is laid over a concrete building application.
Easements are only one item in the overall review of a site. Build them in as a fixed step in the site due diligence checklist from cadastre to project proposal, so they do not become an afterthought.
What to do when you find a blocking burden
Not every burden is a death blow. Once you have identified a registered burden in a construction project, there are typically four routes:
- Design around it. If the building zone still accommodates the project clear of the building line or the corridor, it is solved on the drawing board. Cheapest and fastest.
- Get it cancelled or amended. Easements can be lifted or adjusted — by agreement with the party entitled to enforce, by expropriation, by court ruling, or because they have lapsed. This requires a clear picture of who holds the enforcement right. See how to cancel or amend an easement that blocks development for the procedures.
- Price it in. If the burden can be handled for a fee — a pipe relocation, an agreement with a neighbour — then factor cost and time into the budget, and let it be reflected in the purchase price.
- Walk away. If the burden makes the project unfinanceable and cannot be removed, the most expensive mistake is to discover it after the deal.
What matters is that the choice is made before the deed — while price, conditions, and the exit option are still open.
How to find them early with Arcili
The manual exercise is manageable, but it is easy to skip under time pressure: pull the land registry certificate, read the easements section, request the underlying covenants, plot building lines and corridors onto the cadastre, and hold them up against the building rights in the local plan. It is not hard — it just often gets done too late.
In Arcili, land registration, planning status, BBR (the Buildings & Dwellings Register), and the cadastre are gathered on the same property in the Ejendomme (Properties) module, so the burdens are visible already in the initial screening — not buried in a document someone should have requested. It does not replace the legal review of the individual covenant, but it ensures you know where to look before you negotiate price.
