When you only wanted to redo the bathroom and suddenly you’re talking about “PEM”
I swear I’ve seen this movie a thousand times: you start out excited, browsing floors and faucets… and then someone drops, “you need the City Council’s permission.” And you’re left with the same face you’d make if they told you that to change your tiles you need NASA’s approval.
The first time it happened to me, my brain went straight to: “Wait… what is this, building the Death Star?” And that’s when the key word shows up—the one that rules almost everything here: PEM (Material Execution Budget).
Don’t let the name scare you—it’s simple. PEM is what the work costs on the ground: materials + labor, without VAT and without the company’s profit margin. I explain it like this: PEM is “the meat at the butcher’s,” before the restaurant plates it nicely and charges you gold for it.
Why does PEM matter so much? Because in many municipalities, fees and the construction tax are calculated as a percentage of PEM. That’s why two “similar” renovations can pay very different amounts—not only because of the budget, but because of the local tax ordinance and the procedure you fall under (responsible declaration, minor works, major works, or a new-build permit).
At Your Home in Good Hands, we see it all the time: the shock usually isn’t the construction work… it’s walking into the Urban Planning maze without a map. So let’s make it easy: what you pay, what it usually costs, and how long it can take, no drama—just a clear method.
What the City actually charges you: fees, construction tax, and the “surprise extras”
Here’s the key: when people say “municipal fees,” they often throw everything into the same bucket. Not because they’re careless—because in real life it all lands on your desk together and feels like one big hit.
- Urban planning/permit processing fee
You pay for the administrative handling: opening the file, reviewing it, reporting on it, and so on. It can be a percentage of PEM or a fixed rate depending on the type of work. - Construction tax (ICIO equivalent)
This is the municipal tax tied to carrying out the works. It’s usually a percentage of PEM (and it varies a lot from one municipality to another). - Extras that appear once you’re already in the thick of it
The most common ones:
- Public space occupation fee if you place a dumpster, rubble bag, scaffolding, or store materials on the street (charged by time and/or area).
- Waste deposit/guarantee (a refundable deposit to ensure you manage debris properly; if you prove proper disposal, it’s usually returned under the municipality’s process).
Quick cheat sheet so you don’t mix things up:
| Item | How it’s usually calculated | When it shows up |
|---|---|---|
| Permit processing fee | % of PEM or fixed rate | When you file the application |
| Construction tax | % of PEM | With the permit / self-assessment |
| Extras (street + waste) | Depends on local rules | If there’s a dumpster/scaffolding/debris |
With this in mind, you won’t get blindsided: it’s not “one fee”—it’s a bundle.
The quick rule to estimate the cost without losing your mind
Here’s the friend-to-friend method. It won’t give you the exact number (the local ordinance does that), but it puts you in a really useful range for planning.
1) Ask for the PEM (even if you have an “all-in” quote)
If you only have the final quote, ask: “What’s the PEM?” If they can’t break it out, at least you’ll know the city may calculate on a base that’s different from your “total with VAT.”
2) Use a compass: 5%–7% of PEM (fees + construction tax)
As a quick mental rule so you don’t underestimate, many people use about 5% to 7% of PEM for the permit fee + construction tax.
Important: it’s a planning compass, not a universal law. The real figure comes from your local ordinance and the specific procedure.
3) Add extras if they apply (dumpster and waste)
If there’s a dumpster on the street or lots of debris, assume you might pay public space occupation and/or a waste deposit. Even if it ends up small, it’s better to budget it than to get surprised at the worst moment.
To make it real, here’s a quick two-case example (renovation vs new build):
| Case | PEM (example) | Estimated range (5%–7%) |
|---|---|---|
| Typical bathroom/kitchen renovation | €10,000 | €500–€700 |
| New build (small/medium home) | €120,000 | €6,000–€8,400 |
This doesn’t replace the ordinance, but it kills the anxiety: you’ll know whether you’re dealing with “hundreds” or “thousands.”
How long it takes: from “you can start now” to “make some tea”
Timelines depend less on “is it a bathroom or a kitchen?” and more on which procedure your municipality requires. And differences can be huge between towns (and even between seasons, because planning departments get overloaded too).
Responsible declaration / prior notice (the fast lane)
This is the “file it and go” mode. In many places, if everything is complete, you can start almost immediately (or very soon). It’s basically “I declare I comply”—and if they inspect, you really need to comply.
Permit with prior review (the slow lane)
If the work affects structure, façade, major changes, extensions, protected buildings, or it’s a new build, there’s usually a prior review. That’s when you run into:
- Requests for corrections (“this is missing,” “fix that”)
- Municipal technician timelines
- Department workload
A rough guide to set expectations:
| Procedure | When can you start? | Typical timeframe |
|---|---|---|
| Responsible declaration | Almost immediately if complete | Days / a few weeks |
| Minor works permit | After validation/authorization | Weeks |
| Major works permit | Once the permit is granted | Months (can stretch) |
| New build permit | Once the permit is granted | Months + more back-and-forth |
Mental trick: what stretches timelines isn’t the plaster—it’s the paperwork.
Signs your “simple renovation” might actually be major works
If you see yourself in one or more of these, don’t treat it like a tiny job without checking the procedure:
- You’ll touch structural elements or load-bearing walls
- You’ll modify the façade, balconies, openings, or visible exterior elements
- There’s an extension, added floor, enclosed porch, or volume changes
- The building is protected/listed or under special urban planning rules
- You change the use (for example, commercial space to dwelling) or it affects common areas
This checklist is gold because it prevents the classic: “I thought it was simple, and then they asked for a full project.”
How to avoid surprises without turning this into a bureaucratic novel
Here’s what I’d do before starting—simple version:
- Find your municipality’s local tax ordinance (fee + construction tax).
- Confirm the procedure that applies (declaration, minor works, major works, new build).
- Prepare a decent document pack (description/memo, PEM/budget, drawings if needed, and whatever your technician requires).
- If there’s a dumpster or scaffolding, plan the street occupation from day one.
- Don’t play “I’ll do it without paperwork”—regularizing mid-project is a stress factory.
Back to beers: how not to get hit by surprise costs
In the end, this is about having a map. If you told me tomorrow “I’m starting a renovation” or “I’m doing a new build,” I’d do this:
- Identify the procedure
- Get the PEM
- Estimate with the 5%–7% compass
- Confirm in the local ordinance
- Add extras if there’s street/debris
- File everything complete so you don’t enter the endless correction loop
And when you do it like that, something funny happens: the renovation is still a renovation (dust, decisions, and at least one “why did we choose this color?” moment), but the City Council stops feeling like a final boss fight.
If you want, at Your Home in Good Hands we can help you identify the right procedure and get a realistic estimate range based on your municipality and your project—before you call the contractor and the clock starts ticking.
Frequently asked questions so you don’t get lost in the maze
Are “municipal fees” and the construction tax the same thing?
No. The fee usually covers the administrative processing of your application. The construction tax is a tax linked to executing the works. Often you pay both, which is why people mix them up.
Is PEM the same as the total project quote?
Not necessarily. PEM is usually the “on-site” cost (materials + labor) without profit margin and without VAT. Your total quote may include additional items (profit, VAT, management, etc.). That’s why it helps to ask for PEM—or at least understand what base the municipality uses.
Can I start as soon as I file the paperwork?
It depends. With a responsible declaration/prior notice, many municipalities let you start almost immediately if everything is complete. With a permit (major works or a new build), you normally have to wait for approval.
Is a full renovation always “major works”?
Not always. “Full renovation” doesn’t automatically mean major works. The deciding factors are usually whether you touch structure, façade, load-bearing walls, or whether the building is protected or under special rules. If you’re unsure, treat it as a serious case and confirm before you open the wall.
Do I pay more if they request corrections or additional documents?
Most of the time, corrections trigger back-and-forth that delays the file. Payment rules vary (self-assessment vs provisional/final assessment), so the best move is to avoid requests by filing a complete, well-prepared package from day one.
Do dumpsters or scaffolding always trigger extra charges?
If you occupy public space, it’s common to have a public space occupation fee (by day, by area, or both). The exact amount and steps depend on your municipality, so it’s worth checking before you order the dumpster “for tomorrow.”
