# OVK for property owners and managers

Own or manage property in Sweden from abroad? Here is what you need to know about the **mandatory ventilation inspection**, and how we take care of it.

If you own or manage a residential or commercial building in Sweden, the ventilation system must be inspected regularly under a Swedish law known as **OVK** (*obligatorisk ventilationskontroll*, mandatory ventilation inspection). The obligation rests with the owner, wherever the owner lives. This page explains what that means in practice. For the background, read [What is OVK?](https://www.ovkkollen.se/en/what-is-ovk.md)

## Your obligations as an owner

- **You are responsible.** The property owner is always responsible for having OVK carried out within the correct interval. In a housing cooperative (*bostadsrättsförening*) the board carries the responsibility. A property manager can handle the practical work, but the legal responsibility stays with the owner.
- **Use a certified inspector.** Only certified ventilation inspectors (*funktionskontrollanter*) are allowed to carry out OVK.
- **Inform residents.** Residents or tenants must be told in good time when the inspection will take place and must give access to their homes.
- **Act on deficiencies.** If the inspection finds deficiencies, you must correct them within a set time and have a follow-up inspection.
- **Keep the certificate displayed.** After the inspection a certificate is displayed in the building, and a copy of the protocol is sent to the municipality.

Failure to comply can lead to an order from the municipality and a financial penalty (*vite*), and can affect the value and insurance terms of the property.

## How often is OVK required?

For most apartment buildings and office buildings the interval is **3 years** for buildings with mechanical supply and exhaust ventilation (FT or FTX) and **6 years** for buildings with natural or exhaust-only ventilation (S, F or FX). Preschools, schools and healthcare premises are inspected every **3 years** regardless of system. Detached and semi-detached houses normally need only one inspection when the ventilation system is taken into use. A full table is in [What is OVK?](https://www.ovkkollen.se/en/what-is-ovk.md)

## What we take care of

**Notification of residents.** We provide ready-made notices and, if agreed in advance, we can send them for you.

**Scheduling and access.** We plan the inspection with you so that disturbance is kept to a minimum.

**The inspection itself.** Air flows are measured, fans, vents, filters and ducts are inspected, and the system is assessed against the requirements that applied when the building was constructed.

**Protocol and certificate.** We issue the OVK protocol, send a copy to the municipality and provide the certificate for the building.

**Follow-up.** If deficiencies are found, we help with proposed measures and can coordinate cleaning or air balancing.

## Managing several properties?

We work nationwide and adapt to your structure for notification, invoicing and reporting, so that nothing falls between the cracks across your portfolio.
