2. Apply for building permit from the building control department of your municipality. When you have received the permit, remember to also deliver the water and sewer plans of the property (so-called KVV plans) to the building control department and apply for an approval of the appointed KVV site manager.
In Espoo, deliver one copy of the water and sewer plans approved by the building control department (including water and sewer installations review, layout and floor plan for the water meter premises) to the customer service office of the HSY Espoo water services.
The Building Control Departments of Helsinki and Vantaa will deliver the copies of the plans to HSY.
