GDPR for Owner Associations: What Data You Can Share, and With Whom
Published 7 August 2026 · IgeraSolutions Editorial Team · 10 min read
In short
Under the General Data Protection Regulation (Regulation (EU) 2016/679), an owner association or property manager may process a resident's contact details, ownership records and payment history where this is necessary to run the building — but posting a named debtor's balance on a communal noticeboard, or sharing health information about a resident without a lawful basis, is a breach of GDPR that has already resulted in fines by national data protection authorities across the EU.
Every owner association, residents' committee and managing agent in the EU processes personal data as a matter of course: names, addresses, IBANs, phone numbers, sometimes information about a resident's mobility needs when a lift or ramp is being planned. None of this is optional to collect, and none of it is free to mishandle. GDPR has applied to every EU member state since 25 May 2018, and it makes no exception for the volunteer board of a 20-unit apartment building.
This article sets out, in practical terms, what data an owner association or property manager can lawfully collect and share, which legal basis applies to each use case, and the mistakes that most often turn an ordinary management task — chasing an unpaid service charge, arranging accessibility works — into a data protection complaint.

1. Does GDPR actually apply to a residents' association?
Yes, without exception. GDPR applies to any "controller" that processes personal data of identifiable individuals in the EU, regardless of size or legal form. An owner association — whether it is a formally incorporated entity, an informal residents' committee, or a building managed entirely through a professional property manager — is a data controller the moment it holds a spreadsheet of unit owners' names, phone numbers and payment status.
Where a professional property management company handles the day-to-day administration, the relationship is usually one of joint controllers, or the property manager acts as a processor under a contract with the association (GDPR Art. 28). Either way, someone is legally accountable for how that data is collected, stored, shared and eventually deleted — and "we're just a small volunteer board" is not a defence recognised anywhere in the regulation.
2. What data can lawfully be processed — and on what basis
GDPR Article 6 requires every processing activity to rest on one of six legal bases. In practice, an owner association will rely almost entirely on two of them: legitimate interest and legal obligation, with consent playing a much narrower role than most boards assume.
2.1 Contact details and ownership records
Name, unit number, correspondence address, phone number and email fall squarely within the association's legitimate interest (GDPR Art. 6.1.f) in running the building: convening meetings, sending notices, distributing minutes, and identifying who is entitled to vote. No separate consent form is required for this baseline processing — it is inherent to co-ownership. What is required is transparency: residents should be told, typically in a short privacy notice attached to the association's rules or welcome pack, what is collected and why.
2.2 Payment records and service charge history
Payment history, IBANs and outstanding balances are processed under a mix of legitimate interest (recovering charges the association is owed) and, in several member states, a specific legal obligation under national property law to keep accurate accounts and report them to the general assembly. Retention should be limited to what national civil and tax law requires for accounting and limitation-period purposes — typically five to ten years depending on the member state — not kept indefinitely "just in case."
2.3 Health and disability-related information
This is where associations most often stumble. Health data, including information revealing a disability, is a special category of data under GDPR Article 9 and is subject to a general prohibition on processing, lifted only in specific circumstances. If a resident requests a reserved parking space, a stairlift, or priority access to a lift because of reduced mobility, the association does not need to know their diagnosis — it needs to know that a reasonable accommodation is justified.
In practice this means: request only the minimum evidence needed (often a disability certificate or a doctor's confirmation of functional need, not full medical records), obtain explicit consent from the resident for that specific disclosure (Art. 9.2.a), restrict access to the board member or manager actually handling the request, and never discuss or minute the underlying medical reason in a document that is visible to the wider building. The accommodation itself — a widened doorway, a reserved space — is a legitimate, documentable operational decision; the medical justification behind it is not something the whole assembly needs to see.
2.4 CCTV and access control data
Where an association operates CCTV in common areas, footage is personal data and must be justified by a documented legitimate interest (security of the building), limited to common areas only (never covering private balconies, windows of neighbouring buildings, or public pavements beyond what is necessary), signed with clear notices, and retained for a short, defined period — national guidance from most EU data protection authorities points to 30 days as a reasonable default absent an active incident.
