Hello,

Does anyone have experience with building a garden shed, and what should be considered?

My parents plan to install a prefabricated wooden house of about 25-30m² (270-320 sq ft) on a garden plot in Saxony.
Electricity and water will continue to be supplied from the neighboring property, as before, and both will be connected inside the house. Wastewater is expected to drain safely as it does now. The property will be used as a weekend retreat.
What I am unsure about is how the toilet situation should be handled in the future.

Currently, there is a small garden shed of about 12m² (130 sq ft) on the property. This will be removed to make room for the new house.
The existing shed is located directly on the property boundary along a path, for which there is a shared usage right. From when do the 3m (10 ft) setback requirements from the property line apply here?

According to the city’s website, small structures up to 10m² (110 sq ft) do not require approval.
Does this mean that a building permit or planning permission needs to be submitted?
Does the application have to be signed by an architect or structural engineer?

According to the house manufacturer, a strip or pad foundation is required under the house.
Does a structural engineer also need to be hired separately, or is that included with the prefab homes?

What else should be considered?

A clearance of 3 meters (10 feet) must be observed. You do not need a special permit for this, so it’s not a big deal.

Is that your opinion, or do you have any background information on where this is stated?

I found the following in the Saxony Building Code:

§ 63a Projects Exempt from Approval
(1) The construction and alteration of the following structural works, other facilities, and installations do not require a building permit:
1. Buildings
a) Buildings without habitable rooms, toilets, or fireplaces, if the buildings have a gross volume of no more than 15 m³ (530 cubic feet), no more than 6 m³ (212 cubic feet) in rural areas, and are not used for sales or exhibition purposes,
...
f) Weekend houses on weekend sites with a built-up area of up to 40 m² (430 square feet) and a ridge height of 3.50 m (11.5 feet),
g) Garden sheds in permanent small garden allotment areas according to the Federal Small Gardens Act (BKleingG) of February 28, 1983 (BGBl. I p. 210), as amended most recently by Article 9 of the law of August 18, 1997 (BGBl. I p. 2081, 2111), in the respective current version,


The building exceeds 15 m³ (530 cubic feet),
It is not located in a small garden allotment,
And I am missing the definition of a weekend site. I would imagine that refers more to a plot by a lake.

As long as he does not have a legal dispute initiated by his neighbors, he does not need to worry. Asking his neighbors will clarify the situation.

Well, that's quite a well-founded statement!
Can Musketier then rely on you in case of an emergency?

I will do that 😉

I spoke with my parents again. The garden shed is planned to be right in the middle of the property anyway. Setbacks from the boundaries will be met on all sides. Toward the end of the year, on my advice, they want to schedule an appointment with the building authority to find out whether a building permit / planning permission is required. Then construction can start next year.
