AI in condominiums can save time: answering simple questions, organising documents, summarising minutes. But the same technology makes it possible to create, in an afternoon, a management company website with flawless copy, computer-generated team photos and promises of instant replies. Behind the website there may be no registered company, no office and no managers. In this guide we explain the warning signs, how to check a company before trusting it with the building’s accounts, what Portuguese law says about the administrator’s liability and where AI genuinely helps.
In short
- A well-made website does not prove there is a real company behind it.
- Check the commercial registration, the address, the professional liability insurance and buildings the company already manages.
- The administrator is liable in civil law when they fail to carry out their duties, with or without AI.
- Owners’ data is protected by the GDPR.
- AI is useful for support tasks; decisions and responsibility remain with people.
Companies that only exist on screen
Creating a condominium management brand has never been easier. AI tools generate the logo, the copy, the images and even automatic replies to requests for quotes. The problem is not the technology: it is using it to appear to be something you are not. The signs repeat themselves:
- No visible company tax number (NIPC) and no verifiable address.
- Team photos that appear nowhere else or look computer-generated.
- Claims of «many years of experience» on a website whose domain was registered a few months ago.
- No privacy policy or information on who processes owners’ data.
- Absolute promises, such as a guaranteed reply within minutes for any breakdown, even on stormy days.
- Prices far below the market with no explanation of what is included.
How to check a company
| What to check | Where | What you should find |
|---|---|---|
| Commercial registration | Permanent certificate | A registered company, its purpose and managers |
| Domain date | WHOIS search | A registration date consistent with the experience claimed |
| Insurance | Professional liability policy | Insurer, amount covered and validity |
| Clients | References from buildings managed | Contacts you can confirm |
| Complaints | Complaints Book | A way to complain and any history |
| Personal data | Privacy policy | Data controller and contacts |
The commercial registration is the simplest proof that the company exists:
«A certidão permanente de registo comercial permite o acesso online aos registos e documentos de empresas, sociedades, cooperativas, empresas públicas ou outras entidades que estejam sujeitas a registo comercial.» — gov.pt, Checking the permanent commercial registry certificate
In plain English: the permanent commercial registry certificate gives online access to the registrations and documents of companies, cooperatives, public companies and other entities subject to commercial registration.
Ask the company for the access code to its permanent certificate and check it. For .pt domains, the DNS.PT WHOIS search shows, among other data, the date the domain was registered. Check whether the company has an electronic Complaints Book. And ask to speak to the management of one or two buildings the company already manages.
Liability cannot be delegated to an algorithm
A chatbot can answer a question about the date of the general meeting, but it cannot be held liable for an insurance policy that was not renewed. The law gives the duties to the administrator and holds them liable:
«3 – O administrador de condomínio que não cumprir as funções que lhe são cometidas neste artigo, noutras disposições legais ou em deliberações da assembleia de condóminos é civilmente responsável pela sua omissão […].» — Civil Code, article 1436(3)
In plain English: an administrator who fails to carry out the duties set by this article, by other legal provisions or by decisions of the general meeting is liable in civil law for that failure.
Calling general meetings, preparing the budget, collecting charges, checking the fire insurance, carrying out decisions and presenting the accounts are duties of whoever is elected (article 1436(1)). A company that has no people to carry them out cannot guarantee any of them, however modern its website.
Owners' personal data
A management company processes names, addresses, contacts, debts and sometimes CCTV images. That data is protected by the General Data Protection Regulation. Before hiring, ask who the data controller is, where the data is stored and whether it is used to train AI systems. The CNPD is the supervisory authority in Portugal. The European regulation on artificial intelligence (Regulation (EU) 2024/1689) also sets transparency obligations, such as telling people that they are interacting with an AI system.
Where AI genuinely helps
- Answering frequently asked questions, such as payment deadlines or emergency contacts.
- Organising and searching minutes, accounts and contracts.
- Preparing drafts of notices of meeting and minutes, reviewed by a person.
- Sorting maintenance requests by urgency.
- Helping with voting and counting at remote meetings, under human control.
The rule is simple: AI prepares, a person decides and is accountable. See why managing condominiums the old way is a risk, how our own condominium software works, and why technology and proximity are not a dilemma.
Fake messages in the management's name
AI also makes fake messages more convincing. An email with the management company’s logo asking for charges to be paid to a new IBAN, a message with a link to «settle a debt», a call with a voice that sounds like the manager’s. Before paying or sending data, always confirm through the management company’s usual contact, not the one in the message. A change to the condominium’s bank account should be communicated formally and, ideally, be backed by a decision of the meeting or a signed notice. If you receive a suspicious message, tell the management company and your neighbours.
Before you sign
- Ask for the permanent certificate access code and check the registration.
- Ask for the professional liability policy and check its validity.
- Ask for references from current buildings.
- Book a clarification meeting, in person or by video, with the manager who will look after the building. See why the clarification session is decisive.
- Read the contract and the privacy policy.
- Check that the bank account will be in the condominium’s name.
How Condoroo helps
Condoroo uses technology every day, including AI tools, to organise documents, follow up requests and prepare general meetings. Decisions and responsibility lie with the team: more than 20 professionals who manage more than 600 condominiums. We have professional liability insurance of €500,000, we have held the DECO seal for the third year in a row and the bank account is always in the condominium’s name.
AI in condominiums: frequently asked questions
How do I know whether a condominium company is real?
Ask for the access code to its permanent commercial registry certificate, its address, its professional liability policy and references from buildings it already manages.
Is a website with good reviews enough?
No. Copy, images and even reviews can be generated automatically. Always check the company’s official details.
How can I see how long a website has existed?
For .pt domains, the DNS.PT WHOIS search shows the date the domain was registered.
Can a chatbot replace the administrator?
No. The administrator’s duties, and liability for failing to carry them out, belong to whoever was elected (article 1436 of the Civil Code).
Can my data be used to train AI?
Only under the terms of the GDPR. Ask the company and read the privacy policy before hiring.
Is AI useful in condominium management?
Yes, for support tasks such as answering frequently asked questions or organising documents, always with human review.
