Caderneta Predial
Tax registerRecords fiscal value and registered area. Doesn't confirm that the registered area matches the actual floor plan - a gap that matters at resale.

Automated reminders from Portugal's system
The gap nobody fills
A system built for people who live inside it, operating on people who do not - and residents who do.
HomeOS is built for every owner
Whether you manage your property from London, Amsterdam, or Lisbon, Portugal's system assumes you already know. HomeOS fills that gap.
The notary shook your hand. Your lawyer sent a congratulations email. The keys are yours.
And now you're sitting with a folder of Portuguese documents that took six months to assemble, relating to an asset worth several hundred thousand euros - one you may visit four times a year, or one you pass every day without fully understanding what you own.
The Caderneta Predial tells you the fiscal value and registered area - but not whether that area matches the actual floor plan. The Certidão de Registo Predial confirms ownership as of the date it was issued, but expires in six months and nobody tells you to renew it.
The Licença de Utilização says the building was approved for residential use at some point - not whether the 2019 renovation was licensed.
Then there's the operational layer. IMI lands once a year, sometimes twice. The condominium sends invoices that pile up. The gas installation certification expires and nobody sends a reminder. The EPBD renovation passport deadline passes and you find out from a LinkedIn post.
This is the standard experience for property owners in Portugal. A system that assumes you already know everything it never told you.
What's in your folder - and what it doesn't tell you
The documents. The gaps.
Every property in Portugal generates a set of mandatory documents. Each tells part of the story. None tell the whole story - and the expiry dates are your responsibility.
Certidão de Registo Predial
Expires 6 monthsConfirms ownership and encumbrances on the date it was issued. Expires in six months. No automatic renewal alert exists.
Licença de Utilização
Habitation licenceConfirms the building was approved for residential use at some point. Doesn't tell you whether later renovations were licensed.
Gas Installation Certification
Hard deadline 2028Required under DL 97/2017. Pre-2018 installations face an August 2028 compliance deadline. No centralised reminder system.
Energy Performance Certificate
EPBD linked · May 2026Required for rental and sale. Valid for 10 years. The EU EPBD Directive ties renovation obligations to this certificate.
Condominium invoices & AGM resolutions
OngoingIncludes extraordinary contributions, maintenance votes, and AGM resolutions. Easy to miss. Consequences are not.
HomeOS · What it does
One dashboard. Your property, without the chaos.
Three modules built around organised documents, compliance visibility, and a renovation paper trail.

Document vault
Every document your property generates, stored and tagged in one place. Expiry dates tracked automatically. Nothing lapses without a warning.

- Automatic expiry alerts before documents lapse
- Upload anything; HomeOS reads the dates
- Share access with your lawyer or fiscal representative
MODULE 02
Compliance calendar
IMI, condominium obligations, gas certification, EPC renewal, EPBD deadlines - mapped to your property's specific municipality and building type. The reminders Portugal never sends.

- Gas certification renewal (DL 97/2017)
- EPBD renovation passport deadlines
- Condominium AGM and extraordinary levy tracking
MODULE 03
Renovation history
A full record of what was done to the property and when - licensed works, unlicensed works, everything in between. Export-ready for sale, audit, or EPBD compliance.
