Editorial review 2026-09-12 · Jurisdiction: Sweden — Planning and Building Act chapter 9 marklov as explained by Boverket
Marklov versus bygglov — the ground-works permit is a different Plan- och bygglagen object
Is a Swedish ground-works permit a small building permit, or its own Planning and Building Act object? Boverket’s marklov page, last changed 1 December 2025 and used here from the PBL Knowledge Bank, records the current wording of chapter 9 section 47 as Act 2025:974: a marklov is required for a height change of more than 0.5 metres unless the work only follows the levels the detailed plan already set, for actions the plan says need a marklov, and for tree, forestry or permeability measures where chapter 4 section 10 still applies. The height is measured against the part of the plot where the work happens, not against a distant corner of the same property. Boverket cites Mark- och miljööverdomstolen P 7602–17 for that reading. Chapter 9 section 50 is the no-double-permit rule: if the same work is already covered by a bygglov, a separate marklov is not required. That is not the same sentence as “grading is free because a hall will need a bygglov later.” The later building permit has to actually cover the ground works. After 1 December 2025 a municipality cannot introduce a new, expanded lovplikt for trees or permeability in a plan. Older plan rules can still apply. Reduced lovplikt that a PBL plan introduced expires on 30 November 2027. Förhandsbesked cannot be sought for marklov — the förhandsbesked page already recorded that limit. A marklov is also not a startbesked. Work that needs a marklov still needs the start decision before it begins. A voluntary marklov is allowed under chapter 9 section 52 even when the statute does not require one. That voluntary paper is still not a bygglov and not a reserved hall. Microsoft’s 16 November 2021 Sweden-region note names Gävle, Sandviken and Staffanstorp. EcoDataCenter names Falun. Google names Horndal. atNorth’s 23 February 2026 SWE04 note names Sollefteå. evroc’s 3 February 2025 note names Arlandastad in Sigtuna. None of those pages is a marklov decision. The building-permits page already owns what a bygglov examines. The startbesked page already owns the start gate. This page only asks which published ground-works paper the hall file is sitting on. This is orientation, not counsel.

General orientation. Assess the specific project separately. Applies to: Readers placing a grading, site-preparation or marklov sentence on a Swedish hall file as if a building-permit form already covered the ground works.
Reading order
Seat chapter 9 section 47 before any municipal apply-here page. Marklov is its own object: a height change of more than half a metre on the worked part of the plot, actions a detailed plan requires a marklov for, and — where the plan still says so — trees, forestry or permeability. Write the measured part of the plot and the plan sentence on one line before you say grading is free.
Then keep chapter 9 section 50 on its own row. No separate marklov is required when a bygglov already covers the same ground works. A future hall bygglov that has not been applied for does not cover today’s cut. Boverket’s sister page on marklov outside a plan records a narrower duty outside a detaljplan. Read the plan map before you choose the page.
Then keep förhandsbesked and startbesked on later rows. Förhandsbesked cannot be sought for marklov. A marklov is not a startbesked. After 1 December 2025 a plan cannot introduce a new expanded tree or permeability lovplikt. Reduced lovplikt in a PBL plan expires on 30 November 2027. Those dates are handbook facts. They are not a hall calendar.
Then keep named project rows as geography. Microsoft Gävle–Sandviken–Staffanstorp, EcoDataCenter Falun, Google Horndal, SWE04 Sollefteå and evroc Arlandastad stay operator papers. This register does not publish a measured 0.5-metre cut or a marklov decision for those cadastral units.
- Marklov is its own chapter 9 object. It is not a small bygglov.
- The default height trigger is more than 0.5 metres on the worked part of the plot.
- No separate marklov is required when a bygglov already covers the same ground works.
- Förhandsbesked cannot be sought for marklov. Marklov is not a startbesked.
What a marklov clock and a bygglov clock actually measure
A marklov measures whether the named ground works may be carried out under the plan and the statute. It does not measure the building’s use, the fire section or a reserved feeder. A bygglov measures the building object. When the same application already covers the grading, chapter 9 section 50 keeps a second ticket off the desk. When it does not, the grading still needs its own paper.
The 0.5-metre trigger measures the worked part of the plot. Boverket’s case cite, MÖD P 7602–17, refuses a convenient far-corner reading. A campus-scale cut-and-fill story that never names the measured part is not a marklov file.
The building committee’s prövning of a marklov is not a plan comment and not an environmental permit. Neighbours, the plan’s use provisions and related PBL chapters stay on their own rows. A voluntary marklov under chapter 9 section 52 is still a marklov, not a reserved hall.
What this page does not prove: that every Swedish hall pad needs a marklov; that a 0.5-metre cut on a campus is already measured; that a municipal fee exists at a named number; or that a startbesked has been issued. Those facts need the municipal file.
What named primary sources show
Boverket’s marklov page, last changed 1 December 2025, remains the dated national commentary for chapter 9 section 47 as Act 2025:974, the 0.5-metre trigger, the worked-part measurement, chapter 9 section 50, the 1 December 2025 and 30 November 2027 lovplikt dates, and the voluntary marklov under chapter 9 section 52. Boverket’s pages on marklov outside a plan and on how a marklov is examined remain the neighbouring letterheads.
Planning and Building Act 2010:900 chapter 9, and chapter 4 section 10 for plan-required tree, forestry and permeability rules, remain the statutory papers. The förhandsbesked page in this register remains the source for the sentence that förhandsbesked cannot be sought for marklov. Named operator rows remain geography.
No cited source here publishes a measured 0.5-metre cut, a marklov decision or a municipal fee for a named Swedish hall.
A matrix instead of a grading-is-free slogan
Draw one page with object rows and evidence columns. Marklov, a bygglov that covers the same work, förhandsbesked, startbesked, a plan rule on trees and a named campus town are different columns. Empty cells stay empty. A campus press note is a geography footnote, not a grading decision.
Do not invent a hall pad or a municipal fee from the 0.5-metre sentence. That remains a statutory trigger from one dated Boverket page.
| Object | What a source can show | What this page will not invent |
|---|---|---|
| Marklov | Boverket 1 Dec 2025: PBL ch. 9 § 47 as Act 2025:974; >0.5 m on the worked part | A reserved feeder or a hall pad |
| Bygglov covering the same work | PBL ch. 9 § 50: no separate marklov | That future grading is already free |
| Förhandsbesked | Sister page: cannot be sought for marklov | A location test of the cut |
| Startbesked | Later gate: marked work may begin | The marklov itself |
| Named campus town | Microsoft 16 Nov 2021; Falun; Horndal; SWE04; Arlandastad 3 Feb 2025 | A measured 0.5-metre cut |
Common misreads
The first misread is to treat marklov as a small bygglov. The statute gave it its own section. The second is to measure the 0.5-metre trigger against a convenient far corner of the property. Boverket’s case cite measures the part of the plot where the work happens. The third is to read chapter 9 section 50 as “grading is free because a hall will need a bygglov later.”
The fourth is to apply for förhandsbesked to test a marklov question. The handbook says that paper cannot be sought. The fifth is to treat a marklov as a startbesked. The sixth is to invent a municipal fee or a hall megawatt. The seventh is to collapse this page into the förhandsbesked page or the kontrollplan page.
What to ask next
Ask whether the detailed plan already sets the finished levels, whether the measured cut exceeds half a metre on the worked part of the plot, and whether a bygglov application already covers the same ground works. Keep förhandsbesked and startbesked on later rows.
Then open the building-permits page, the förhandsbesked page, the startbesked page and the detaljplan hub. If the operator will not name the measured part of the plot and the plan sentence, record the gap. Do not fill it from a site-preparation slide. This page is not legal advice.
- Does the plan already set the finished ground levels for the worked part of the plot?
- Is the measured height change more than 0.5 metres on that part?
- Does a current bygglov application already cover the same ground works?
- Has förhandsbesked been sought for a marklov question?
- Has a campus town been treated as a grading decision?
What this does and does not prove
This page proves that Boverket already publishes marklov as its own chapter 9 object, with a half-metre trigger on the worked part of the plot and a no-separate-marklov rule when bygglov already covers the same work — and that those facts are not a reserved hall megawatt.
It does not prove that a named Swedish hall pad needs a marklov. It does not invent a measured cut for Horndal or Arlandastad. It does not treat a campus press note as a grading decision.
Empty cells stay empty. Until a later primary source names the measured part of the plot and the dated municipal decision, the marklov clock stays a method, not a census. DataCenterSweden records the method.
