Overview

Tanum has had a plot queue for places including Fjällbacka, Grebbestad, Hamburgsund and Resö, but says the queue is being phased out. Read the current sale rules rather than relying on an old queue position. Once you find a plot, check its planning rules and whether water and wastewater will be public or private.Plans for new homesWater and wastewater

Planning & detailed development plans

Tanum lists adopted detailed plans by locality, including Tanumshede, Grebbestad and Fjällbacka. Open the document for the exact property you are considering. It may control building area, position and design differently from the next area. Ask the municipality for help finding the right plan if the property reference or an older map is unclear.Adopted detailed plans

Building permits

Tanum's permit guide explains that a new home needs more than an elevation drawing. The site and ground plans should show its position, access, parking and how water, wastewater and rainwater will be handled. Check which documents your plot needs before ordering drawings. Wait for the formal start notice before work begins.Your application step by step

Water services vary across Tanum

Water & wastewater

Tanum describes both public and private water and wastewater as common in the municipality. Check the specific plot: can it connect to the public network, or does it need a well and private wastewater system? A new private wastewater system needs permission. Investigate this early, particularly for a coastal or rural property where space and water conditions affect the solution.Water and wastewater

Maps & documents

Tanum says a new-build map is normally needed for a new home inside a detailed-plan or continuous built-up area. It provides boundaries, buildings and levels for the site plan. The municipality notes that preparation time varies during the year. Ask the map and permit teams what your location needs before setting the application schedule.When is a new-build map needed?

Coast and inland mean different routines

Living in Tanum

Tanum includes inland Tanumshede and coastal places such as Grebbestad, Fjällbacka and Hamburgsund. A seaside setting may appeal, but daily journeys and services vary between these towns and farther inland. Visit the plot outside the holiday season and test the route to work, school and shops before deciding.About Tanum
