What Actually Changed in the 2026 Czech Building Law?
The 2026 Czech building law (zákon č. 283/2021 Sb., the new Building Act) replaced a system that had been frustrating homeowners, developers, and tradespeople for decades. If you own property in the Czech Republic — or you're planning a renovation, extension, or new build — these changes affect you directly. The short version: the permit process is faster, more of it happens digitally, and some smaller projects no longer need a full building permit at all.
But "simpler" doesn't mean "no rules." The new law reorganised which authority handles your application, changed timelines, introduced a single digital portal, and redefined what counts as a minor modification versus a major construction project. Below is a practical breakdown of every change that matters if you're a homeowner in Czechia.
The Old System vs. the New: Why the Law Changed
Under the previous Building Act (zákon č. 183/2006 Sb.), getting a building permit in Czechia was notoriously slow. Projects routinely waited 12–18 months for approval. The process involved multiple authorities — environmental, heritage, fire safety, hygiene — each with separate proceedings. Neighbours could delay your project with repeated objections, and the paperwork was almost entirely paper-based.
The new law aims to fix this by:
- Creating a single permitting authority — one building office handles your entire application instead of forcing you to collect approvals from a dozen separate agencies
- Setting strict decision deadlines — authorities must issue a decision within 30 days for simple builds and 60 days for complex ones (previously there was no enforceable deadline)
- Digitising the process — a new online portal (Portál stavebníka) lets you submit applications, track progress, and receive decisions electronically
- Reducing the number of proceedings — the separate zoning decision (územní rozhodnutí) and building permit (stavební povolení) are merged into a single permit
For homeowners, this means less waiting, fewer offices to visit, and — in theory — a much more predictable timeline for your project.
What Homeowners Can Now Do Without a Full Permit
One of the most impactful changes is the expansion of projects that require only a notification (ohlášení) or no permit at all. This matters if you're planning smaller work on your house or apartment.
Projects that now need no permit or notification
- Fences up to 2 metres high
- Garden sheds, gazebos, and similar structures up to 40 m² (previously 25 m²) with a height limit of 5 metres, on your own land
- Swimming pools up to 40 m² on your property
- Interior modifications that don't affect load-bearing walls, fire safety, or the building's external appearance
- Replacing windows and doors with identical dimensions
- Solar panel installations on existing rooftops (within certain size limits)
Projects that need only a simple notification
- Detached houses up to 80 m² footprint and two storeys (on land zoned for residential use)
- Extensions that don't exceed 40 m²
- Garage constructions within size limits
- Certain changes to the building's purpose (e.g., converting a ground-floor shop into a flat, subject to conditions)
The notification process is far simpler: you submit the form, and if the authority doesn't object within 30 days, you can proceed. Compare that to the old system where even a garden shed could trigger months of paperwork.
Important caveat: if your property is in a heritage zone (památková zóna), national park, or other protected area, stricter rules still apply regardless of project size. Always confirm with your local building authority if you're unsure.
The New Digital Portal: Portál Stavebníka
The Portál stavebníka is the single online system where all building-related applications are submitted and tracked. For expats in the Czech Republic, this is both good and bad news.
What works well
- You can submit your application entirely online — no need to physically visit the stavební úřad (building office)
- All communication with the authority happens through the portal, with automatic notifications
- You can track the status of your application in real time
- Project documentation can be uploaded digitally (PDF/A format required for technical drawings)
What's challenging for English speakers
- The portal is currently only in Czech — there is no English-language version
- You need a Czech electronic identity (eIdentita) or a datová schránka (data box) to log in
- All submitted documentation must be in Czech
If you don't speak Czech fluently, you'll likely need a Czech-speaking project manager or general contractor to handle the submission process on your behalf. Many contractors experienced with expat clients offer this as part of their service.
How the New Law Affects Renovation Projects
If you're renovating an apartment or house in Czechia, the practical impact depends on the scope of your project.
Cosmetic renovations (no permit needed)
Painting, new flooring, replacing kitchen cabinets, tiling a bathroom, updating electrical outlets within existing circuits — none of this required a permit before, and it still doesn't. You can hire tradespeople and start immediately.
Structural renovations (notification or permit)
If your renovation involves removing or modifying load-bearing walls, changing the layout of plumbing risers, adding or removing windows, or changing the building's energy profile, you'll need either a notification or a full permit depending on the extent of the work.
The key change: under the new law, the merged single-permit process means you no longer need a separate zoning decision even for major interior restructuring. One application, one decision, one timeline.
What about SVJ approval?
If you live in a bytový dům (apartment building) managed by an SVJ (společenství vlastníků jednotek — homeowners' association), the building law change doesn't override SVJ rules. You still need SVJ approval for any work that affects common areas, building facades, shared utilities, or structural elements. The SVJ approval process is governed by civil law, not the Building Act, so it remains unchanged.
New Rules on Neighbour Objections
This is one of the most significant changes for homeowners. Under the old law, neighbours could file objections that essentially paused your permit process indefinitely, sometimes adding years to a project timeline.
The 2026 law changes this in three ways:
- Defined objection window: neighbours must submit objections within a strict 30-day period after being notified. Late objections are not accepted.
- Limited scope of valid objections: objections must relate to a direct, demonstrable impact on the neighbour's property — shadow cast, noise, structural risk, etc. General complaints ("I don't like the design") are not valid grounds.
- Authority must decide regardless: the building office must issue its decision within the statutory deadline even if objections are pending review. The objection process runs in parallel, not sequentially.
This doesn't mean neighbours have no rights — they absolutely do. But it prevents the situation where a single objection could stall a project for a year or more while bureaucratic appeals wound through the system.
Deadlines That Are Actually Enforced
The new Building Act introduces something the old law lacked: consequences for the authority if they miss their decision deadline.
- 30 days for simple projects (notifications, small builds)
- 60 days for complex projects (large builds, projects in protected areas)
- If the authority fails to decide within the deadline, the application is automatically approved (so-called "fiction of consent")
In practice, this mechanism is still being tested, and there are reports that some offices are finding procedural ways to extend timelines. But the legal framework is now much more homeowner-friendly than before. If your application is complete and correctly submitted, the clock starts ticking — and the authority knows it.
What This Means If You're Planning a Project in 2026
Here's the practical takeaway for homeowners in the Czech Republic right now:
- Check if your project actually needs a permit. The expanded list of permit-free modifications means your renovation might not require any official approval. Confirm with your local stavební úřad or your contractor.
- Hire a contractor who understands the new system. The transition period means some professionals are still learning the new procedures. Ask specifically whether they've submitted projects through the new digital portal.
- Budget for project management if you don't speak Czech. The portal and all official communication are in Czech. A Czech-speaking project manager or contractor is not optional for most expats — it's essential.
- Get your documentation right the first time. The faster deadlines only help you if your application is complete. Incomplete submissions get sent back, and the clock resets.
- Keep written records of everything. Get written quotes, written contracts, and keep copies of all submissions. The digital portal helps with this, but maintain your own records too.

- Neighbour objections are now time-limited and must relate to demonstrable property impact
- If the authority misses its deadline, your application is automatically approved
- SVJ rules in apartment buildings still apply separately — the new law doesn't change those
- For expats, a Czech-speaking general contractor or project manager is practically essential for navigating the system
