# Find the year a house in Czechia was built

> Search the address and see the house’s completion period, floors and height, wherever the register records them.

## What the record says about a house’s age. Completion period, floors and size in one place.

- **Completion period.** From the register, where known. A date entered in bulk for a whole municipality is shown as a period. Where it is missing, the record says “unknown”.
- **Height and volume.** From the building’s outline, always marked as measured or estimated.
- **Heat demand.** The yearly heat demand worked out from the house’s geometry and the local climate. Useful when you plan a renovation.

## From address to a year you can rely on. Three steps.

1. **Find the house.** Type the address or click the house on the map.
2. **Read the period.** It is in the register section, with the floors and the use. The official record is also in [RÚIAN’s public remote access](https://vdp.cuzk.gov.cz/), the state register of addresses and buildings.
3. **Check the papers.** The exact year is in the occupancy decision or consent (kolaudace) at the building authority, and often in the energy performance certificate.

## Year built questions. What the record holds, and what it does not yet.

### Why does a house show a period and not an exact year?

For many older houses the register gives a date entered in bulk, such as the same day for a whole municipality. Such a date looks exact but is not, so baseray shows it as a period.

### Is the year of occupancy approval the same as the year built?

The year built is usually taken to be the year of completion, that is, of the occupancy approval (kolaudace). Building may have started several years earlier, and the house may have been renovated later.

### Can I find the year built in the cadastre?

No. The cadastre records plots, buildings and owners. The completion date is recorded, for some buildings, by the RÚIAN register.
