Adding a dome to an existing house is subject to local zoning regulations, which vary from one area to another.
You might want to consider extra revenues and think about building a short term rental dome for exemple, or a glamping unit, or off the grid dome, for guests.
In some zones, only one main dwelling is allowed, meaning that adding another full living space might not be permitted. However, certain cities may allow smaller structures, like a dome, as an accessory use or as a simple shed without kitchen or plumbing. To determine whether you can add a dome to your property, it’s crucial to check the specific zoning maps and regulations set by your local municipality.
