Home / Antenna on a housing association roof
You own your flat, a radio licence is in the drawer and an antenna in the box — and between you and the bands stands the housing association board. This guide brings together in one place everything that works in this conversation: the regulations, case law, ready answers to common objections and a template letter to the association that you can print and submit. This is about installations up to 3 metres high — a typical base antenna for 2 m and 70 cm.
If you’ve no time for the whole thing — this is the crux. The rest of the page expands on these four points.
An antenna with a height not exceeding 3 m installed on a building does not require either a building permit or a notification — art. 29(4)(3) of the Building Law (Prawo budowlane). You don’t go to any authority.
The roof is common property (art. 3(2) uwl), of which you are a co‑owner. Art. 12(1) of the Act on Ownership of Premises (ustawa o własności lokali) gives you the right to use it in common in line with its purpose — and roofs have always carried chimneys, services and antennas.
Consent to install a small, reversible installation is an act of ordinary management — and the board takes such decisions independently (art. 22(1) uwl). No meeting or vote is needed: written consent from the board is enough.
Freedom to communicate and to receive information is protected by the Constitution (arts 49 and 54) and by art. 10 ECHR. Strasbourg has already held that evicting a tenant for a satellite dish breaches the Convention.
It’s the only threshold that really matters on the administration side. Below it you’re outside the whole building procedure.
The Building Law (Prawo budowlane) of 7 July 1994, art. 29(4)(3): neither a building permit nor a notification is required for carrying out construction works consisting of installing on buildings (…) equipment, including antenna support structures and radiocommunication installations, as well as accessories and power equipment associated with such devices, with a height not exceeding 3 m.
A typical 2 m and 70 cm base antenna is 2–2.5 m long. Together with a short chimney mount or a wall bracket you’ll be within the limit with no trouble. That means: no application, no notification, no design documentation, no fee.
The same structure with a height above 3 m falls under art. 29(3)(3) — it requires notification to the architectural and building administration authority (the starosta or the mayor of a city with county rights) under art. 30. You still don’t need a building permit — but there’s a procedure, tacit consent and the possibility of the authority’s objection.
If the building is entered in the heritage register or lies in an area entered in the register, the exemptions of art. 29 work differently — the works require a notification, and to it you must attach the permit of the provincial conservator of monuments (art. 29(7) of the Building Law in conjunction with the heritage protection regulations). Check this before you write to the association — in such a building the argument looks different.
You measure the entire installed structure — mast plus antenna — not just the bit sticking up above the ridge. A 2.5 m antenna on a half‑metre bracket is already exactly 3 m. If you’re on the borderline, choose a shorter support: the difference between ‘no formalities’ and ‘notification’ is huge when talking to the association.
This is the crux of the dispute — and it’s where both sides most often get their rights wrong.
Art. 3(2) of the Act on Ownership of Premises (ustawa o własności lokali): the common property comprises the land and those parts of the building and installations which are not for the exclusive use of the owners of the individual premises. The roof, facade, chimneys and service risers — all of that is common, and you are their co‑owner. So you’re not asking for access to someone else’s property, but to use your own, in the part corresponding to your share.
Art. 12(1) uwl: the owner of a unit has the right to use the common property in common in accordance with its purpose. The roof of a multi‑unit building has for decades also served a technical function — carrying chimneys, services and antennas. Using it for that purpose is in line with its purpose, not a change to it.
Art. 22(1) uwl: acts of ordinary management are taken by the board independently. Installing a small antenna system falls within those bounds — it doesn’t change the purpose of the common property, isn’t a superstructure or reconstruction, doesn’t affect the building’s structure, is fully reversible and imposes no costs on the association.
This is confirmed by art. 22(3) uwl, which lists matters that go beyond ordinary management — superstructure and reconstruction, a change to the purpose of part of the common property, division, acquisition of property. Antenna installation isn’t on that list. In practice, the board just as independently agrees to satellite dishes, air‑conditioners or cameras.
There is a single boundary — art. 12(1), second sentence, uwl and art. 206 of the Civil Code: you must use it in a way that does not hinder others’ use. An antenna weighing a few kilograms on a chimney does not breach that condition.
Small association (up to three units) is governed not by the Act on Ownership of Premises, but by the Civil Code provisions on co‑ownership. For acts of ordinary management the consent of a majority of co‑owners calculated according to their shares is sufficient (art. 201 Civil Code). The path is different; the substantive arguments remain the same.
The most common mistake boards make: confusing the right to set conditions with the right to refuse arbitrarily. They are not the same.
| May | May not |
|---|---|
| Specify the method of installation: no interference with the roof covering, on chimney clamps, by a qualified installer | Refuse without stating a substantive reason or relying solely on aesthetics |
| Indicate a location less visible from the street, provided this does not worsen the station’s operating conditions | Demand a building design and a building permit where the law does not require them |
| Require reinstatement after removal and repair of any damage | Send the matter to a general meeting and make consent conditional on collecting neighbours’ signatures |
| Require temporary removal for the duration of roof renovation | Order removal of an existing installation without demonstrating damage or risk |
| Set a reasonable fee for using the common parts (a benefit of the association, art. 12(2) uwl) | Set a prohibitive fee that in practice amounts to a ban, or vary fees arbitrarily |
| Require public liability insurance and nomination of the person responsible for the installation | Make consent conditional on giving up statutory rights or on the consent of all neighbours |
Order matters. Most cases are lost not on the law, but because someone started with installation and ended up with a demand to take it down.
Antenna model, its length, weight, mounting method, total height of the structure, transmitter power and operating bands. Attach the manufacturer’s datasheet. Specifics defuse most fears even before any discussion.
e.g. Diamond X-200N · 2.5 m · 1.6 kg · chimney clamps · 2 m and 70 cm · 100 WThe register of monuments, the municipal monument register, conservation protection in the local plan. If the building is protected — you need a separate conservator’s permit and that changes the whole conversation.
Not a ‘test’ email. A letter with the date, a description of the installation, the legal basis and a specific demand: the board’s consent and written confirmation within a set timeframe. You’ll find a template below. Keep the proof of delivery — that’s what starts the deadlines.
Write into the letter yourself: installation by a qualified contractor, without breaching the roof covering, public liability insurance, repair of any damage, temporary removal for the duration of any renovation, reinstatement afterwards. A board with nothing left to add will find it much harder to refuse.
An oral “all right, go and hang it” is worthless when the board or the administrator changes. Ask for a written statement with a signature, date and a list of the agreed conditions — one sheet of paper saves two years of grief.
An antenna put up “on the sly” turns the tables: you become the party that has infringed someone else’s rights, and the association gets a ready-made claim for reinstatement. Patience at this stage is cheap; lack of it — is not.
If the board fails to reply or refuses without giving a reason, send a notice with a specific deadline and a request to indicate the circumstances justifying the refusal and the conditions upon which consent will be granted. Only then does a sensible civil route open up — described below.
Eight lines you’ll hear from the board — and what you can say back without raising your voice.
| Objection | Response |
|---|---|
| “You need a building permit” | No. An installation up to 3 m on a building structure requires neither a permit nor a notification — article 29(4)(3) of the Building Law (Prawo budowlane). It’s enough to cite the provision and state the height of the structure. |
| “This is a matter for a meeting, not for the board” | Matters of ordinary management are handled by the board on its own (art. 22 ust. 1 uwl), and installing a small, removable installation fits within those limits — it’s not on the list of matters exceeding ordinary management in art. 22 ust. 3. The board agrees to satellite dishes or air-conditioning units on its own, after all. |
| “It spoils the building’s appearance” | Aesthetics on its own is not a legal basis for refusing to use the common property in line with its purpose. It can be taken into account in the conditions — colour, placement on the courtyard side, a mast instead of a lattice tower — but not as grounds for a ban. |
| “It will damage the roof and we’ll lose the warranty” | Propose a non-invasive installation: chimney clamps or a wall bracket, without penetrating the roof covering. Add public liability insurance and a written undertaking to repair any damage. Once a risk has been mitigated, it stops being an argument. |
| “The radiation will harm residents” | Permissible electromagnetic field levels in Poland are defined by the Regulation of the Minister of Health of 17 December 2019. An amateur station operates intermittently, at powers on the order of tens of watts, with an antenna elevated above where people are. State the EIRP, the distances and — if needed — offer to measure. Details in the section on EMF below. |
| “It will interfere with television and the internet” | Amateur equipment must meet electromagnetic compatibility requirements, and the operator is responsible for resolving any interference he actually causes. Propose a clause in the consent conditions: in the event of confirmed interference you will take remedial action. A purely hypothetical allegation does not justify a refusal. |
| “The antenna will come off in a gale” | Manufacturers state the permissible wind speed for the mast and the antenna. Attach the datasheet, indicate a contractor with the necessary qualifications and insurance. It’s the same level of risk as the communal TV antenna that has stood there for years. |
| “We’ll agree, but for 300 PLN per month” | Charging is permissible, but it must relate to actual use of the common part. A rate that in practice amounts to a ban is an abuse of right (art. 5 k.c.) and a breach of the principles of proper management — and, incidentally, hard to defend to the other owners. |
Tone counts for more here than legal provisions. A housing association is neighbours, not a public authority — and a court case with the people next door costs more than the antenna. Start with a conversation and specifics, save the legalities for the second paragraph of the letter, not the first sentence of the conversation.
It comes up almost every time. It almost always rests on an association with a mobile base station, which has different power, duty cycle and purpose.
Permissible electromagnetic field levels in the environment are set by the Regulation of the Minister of Health of 17 December 2019 — it concerns places accessible to the public and applies to every installation, regardless of its size.
Environmental classification is a separate thing: the Regulation of the Council of Ministers of 10 September 2019 on projects likely to have a significant impact on the environment (Dz.U. 2019 poz. 1839). Radiocommunication installations fall under it only after exceeding EIRP thresholds linked to the distance to places accessible to the public — and, importantly, there is no exemption there for the amateur service. It’s worth calculating where you stand before someone calculates it for you.
EIRP is the transmitter power multiplied by the antenna gain (minus the losses in the coax). With 50 W at the antenna input and 6 dBi antenna gain the EIRP is approx. 200 W; with 100 W and 8 dBi — approx. 630 W. Distance is measured from the electrical centre of the antenna in the main beam axis, and for a vertical that axis lies horizontally — i.e. towards neighbouring windows, not downwards to the flats under the roof.
In practice the strongest argument is a trio of numbers: power, antenna gain and the distance to the nearest place where someone is present. Add to that the fact that an amateur station transmits for a fraction of the time, not continuously.
| EIRP of a single antenna | Places accessible to the public closer than | Effect |
|---|---|---|
| from 15 W | 5 m | a project that may potentially have a significant impact on the environment § 3(1)(8) of the Regulation of the Council of Ministers of 10.09.2019 |
| from 100 W | 20 m | |
| from 500 W | 40 m | |
| from 1000 W | 70 m | |
| from 2000 W | 100 m | a project that is always likely to have a significant impact § 2(1)(7) of that Regulation |
| from 5000 W | 150 m |
Results of electromagnetic field measurements in Poland are publicly available in the SI2PEM system (si2pem.gov.pl). If there is a mobile operator’s mast nearby, it’s worth showing neighbours what levels occur there already today — your antenna usually pales into insignificance by comparison.
The board’s position is not a judgment. The right to make joint use of the common property flows directly from the statute and can be enforced — precisely so that it doesn’t depend on someone’s mood.
Before you go to court, send a notice: ask them to indicate the specific circumstances that justify the refusal, and the conditions upon which consent will be granted. Set a realistic deadline — 14 or 30 days.
This letter does two things at once. Some boards simply give way because they have nothing to put in the ‘reason’ box. And if they don’t — you have it on paper that the refusal had no substantive justification, and that is the best possible evidence in any further proceedings.
The legal basis for the claim is art. 12(1) of the Act on Ownership of Premises (ustawa o własności lokali) in conjunction with art. 206 of the Civil Code (Kodeks cywilny) — allowing joint use of the common property to the extent corresponding to your share and the property’s intended purpose.
Also helpful is art. 5 of the Civil Code (k.c.) — the prohibition on exercising a right contrary to its socio‑economic purpose and the principles of social coexistence. A refusal whose only aim is to hinder a neighbour’s lawful activity falls into this category.
Collect evidence from day one: delivery confirmations of letters, correspondence with the board and the administrator, notes from conversations, photos of other antennas and devices already mounted on the same roof. These are often the strongest — they show you were held to a different standard.
An application for consent with legal justification. You fill in the details, print it, and submit it with proof of receipt.
The letter is firm but not combative — the aim is written consent, not a court case. If the association has its own application form, treat this document as an attachment providing the justification.
A complete set of references worth having to hand when speaking with the board — and which the template letter quotes verbatim.
One note about being fair in your argument: there’s a claim online that the housing association has no say in the matter. That’s shorthand. The roof is communal, so the management can set conditions for installation and the location — however, any refusal must have objective grounds. A letter based on this accurate version is much harder to knock down than one that relies on a non-existent ban on refusal.
This material is for information and comes from a radio amateur’s perspective, not a law firm’s.
Regulations do change, and every housing association has its own agreement, rules and history — some even have the management of the common property regulated differently from the statutory rules. Before taking the matter to court, check the current wording of the provisions cited and — if the stakes are higher — have a lawyer review your letter. Legal position as at August 2026.
If you’ve gone through this process yourself and something worked differently from how I’ve described it here — drop me a line. I’ll be happy to update the guide with experiences from real cases. 73!
