§ 6 ThürBO

# Abstandsflächen in Thüringen

In Thüringen the depth of the setback area is 0.4 H, at least 3. m. The governing provision is § 6 ThürBO. H is the wall height from ground level to the point where the wall meets the roof surface.

The dimensions

## What § 6 ThürBO requires

| Standard factor | 0.4 H |
|---|---|
| Minimum depth | 3. m |
| Commercial and industrial zones | 0.2 H – gilt auch für gewerbeähnliche Sondergebiete |
| Central area | no separate rule — the standard factor applies |
| Roof allowance | Das Land kennt keine anteilige Dachanrechnung. Die Wandhöhe H wird stattdessen unmittelbar an der Dachhaut bzw. abschnittsweise ermittelt. H wird lotrecht von jedem Punkt der Wandoberkante oder der Dachhaut ermittelt. |
| Special rule for residential buildings | 3 m genügen für ALLE Gebäude der Gebäudeklassen 1 und 2 mit höchstens drei oberirdischen Geschossen – nicht nur für Wohngebäude. |

Work it out yourself

## Calculating Abstandsflächen in Thüringen

Set eaves height, roof pitch, building depth and distance to the boundary — the required depth is calculated under § 6 ThürBO as you go. The roof allowance is what stands out: the same building yields different values of H across the 16 states.

Under § 6 ThürBO

6.00 m

35 °

10.00 m

3.00 m

Ridge above eaves 3.50 m

of which counted 3.50 m

governing height H 9.50 m

required depth 3.80 m

The setback area extends 0.80 m beyond the boundary. 3.80 m would be required, 3.00 m are kept.

A symmetrical gable roof and level ground are assumed. The figure is geometric, not a statement about permissibility: a local by-law, a development plan or a building encumbrance can set different dimensions.

Worked through

## Worked examples at a glance

Depth = 0.4 × H, but never less than 3. m. These values apply to a wall in the standard case; commercial zones, core zones and privileged boundary structures follow the figures above and below.

| Wall height H | Calculation | Depth of the setback area |
|---|---|---|
| 3. m | 0.4 × 3. = 1.2 m → minimum applies | 3. m |
| 4.5 m | 0.4 × 4.5 = 1.8 m → minimum applies | 3. m |
| 6.5 m | 0.4 × 6.5 = 2.6 m → minimum applies | 3. m |
| 9. m | 0.4 × 9. = 3.6 m | 3.6 m |
| 12. m | 0.4 × 12. = 4.8 m | 4.8 m |

Building on the boundary

## What may stand on the boundary in Thüringen without a setback area

Garages, carports and garden sheds may stand directly on the property boundary under narrow conditions. The dimensions differ in every state.

| Height | 3. m |
|---|---|
| Length per boundary | 9. m |
| Total length along all boundaries | 18. m |
| Additional conditions | die Grenzbebauung steht in § 6 Abs. 7, nicht wie sonst in Abs. 8. Die 18 m fassen die Nummern 1, 2 und 4 zusammen. Dächer bis 45° erzeugen im Grenzfall keine Abstandsfläche; Terrassen bis 1 m sind privilegiert. |
| Habitable rooms and fireplaces | Aufenthaltsräume und Feuerstätten ausgeschlossen |

In comparison

## What is different in Thüringen

Die 3-Meter-Regel gilt für alle Gebäude, nicht nur für Wohngebäude – Thüringen ist damit bei Nebengebäuden großzügiger als jedes andere Land.

On the roof allowance: Das Land kennt keine anteilige Dachanrechnung. Die Wandhöhe H wird stattdessen unmittelbar an der Dachhaut bzw. abschnittsweise ermittelt. This system is shared by 4 of the 16 states. The formula that guides usually claim applies across Germany — "over 70° in full, over 45° one third" — applies in only four.

## What this page does not answer

These figures reproduce the state building code. A local by-law, a development plan or a registered building encumbrance can set different dimensions — and there is no nationwide register of such by-laws. Only the building authority's own information is binding.

Also not covered: provisions in the development plan, registered building encumbrances, the duty of mutual consideration between neighbours, fire-safety distances, and whether a project is exempt from a permit.

And the most common error: exempt from a permit does not mean exempt from setbacks. A carport that needs no building application must still keep the setback areas.
