4. Municipalities may publish the geobase data through their own geoservices and provide it to third parties.

5. Within 5 working days, the Department for Spatial Planning integrates the binding geobase data and regulations received from the municipality and its data management office into the cantonal geodatabase and forwards confirmation to the Department for Geoinformation that the data meets the requirements described in Article 5, Paragraph 2 of the Federal Ordinance on the Cadastre of Public-Law Restrictions on Landownership (ÖREBKV)[6].

6. The Department for Geoinformation publishes these through the cantonal geoservices and in the ÖREB cadastre.

1. In cases of differing interpretations regarding the course of zoning boundaries that do not lie on parcel boundaries, the municipality shall reach an agreement with the leading Office for Spatial Planning, the municipal data management office, and the concerned landowners on a common determination.

2. The municipal data management office shall record the result of the agreement and incorporate it into the binding geospatial dataset. It archives this dataset and makes it available to the Office for Spatial Planning pursuant to § 3b para. 5.

3. If no agreement can be reached, the municipality shall issue an order.

1. In the event of a change in the coordinates of the official survey, particularly as a result of initial surveys, renewals, or a change in the reference framework, the data management offices of the municipalities shall, in consultation with the Office for Spatial Planning and the Office for Geoinformation, geometrically adjust the dataset of the relevant spatial planning to the survey within a reasonable period of time.

1. The Cantonal Concept of Spatial Development and the Cantonal Structure Plan encompass the following subject areas

a. Settlement,

b. Nature and Landscape,

c. Transportation,

d. Supply and Disposal, and other Land Uses.

1. If the municipalities, within the scope of their land-use planning, determine that deviations from the statutory building distances along cantonal roads, public waters, and railway lines necessitate the delineation of building lines, they shall request the Building and Environmental Protection Directorate to declare within 3 months whether it intends to establish the building lines itself or will leave the delineation of the building lines to the municipality.

2. Should the Building and Environmental Protection Directorate waive the delineation of building lines, it shall inform the municipality of the conditions that must be observed.

3. Within the framework of a preliminary examination procedure, the Building and Environmental Protection Directorate determines whether the cantonal conditions are being complied with.

1. If no objections have been raised during the public notification procedure against a cantonal land use plan, or if raised objections have been resolved with legal finality, the Building and Environmental Protection Directorate shall issue a certificate of legal finality.

1. In consideration of public and private interests and in acknowledgment of the special circumstances of the individual case, the municipal council can apply for exceptions to the building permit authority, providing written justification, provided that this is stipulated in the zoning regulations.

2. Unless the municipalities enact other provisions, this particularly applies

a. when the application of these regulations renders an architecturally and urbanistically reasonable solution impossible;

b. when it achieves a better integration into the valuable historical town center;

1. Natural Terrain is defined as

a. the natural, original topography of the construction site; or

b. the topography as it has existed for at least 30 years prior to the construction application.

2. If the terrain has been altered within the last 30 years and an accurate determination of the natural terrain is not possible, or only possible with disproportionate effort, due to artificial changes to the terrain (structures and installations), even after reviewing previous construction permit documents, the topography relevant to the construction project shall be determined by the construction permit authority after consulting the municipality.

1. The prevailing terrain is considered to be the naturally formed land contour. If this cannot be determined due to previous excavations and fillings, the natural contour of the surrounding area shall be used as a basis. For planning or development purposes, the prevailing terrain may be determined differently in a planning or building permit procedure.

2. If the terrain has been altered, the contour relevant to the building project shall be determined by the building permit authority after consultation with the municipality.

1. Provisions Regarding the Measurement of the Building Profile and Roof Structures Are Established in the Zoning Regulations.

2. The municipalities illustrate in the accompanying report the effects on the long-term development possibilities of the surrounding districts and coordinate them with the district planning.

3. In justified exceptions, such as in urban planning with special locations, deviations from the shadow casting rule according to paragraph 1 letter b may be permitted.

4. The municipal council requests the approval of the deviation according to paragraph 3 from the government council with the application for approval of the district plan.

1. A retail unit is defined as one or more retail enterprises (shopping centers) with an unrestricted customer base and a product range for daily or periodic needs. They may include specialty shops, service establishments, showrooms, restaurants, etc.

2. Retail units must structurally and in terms of accessibility form a cohesive unit.

3. Retail units with a sales area of more than 5,000 square meters of net shop area must meet increased location requirements regarding central function, accessibility, connection to public transportation, and minimal impact on residential areas.

2. Retail units with more than 5,000 m² of net sales area must be well accessible by public transport.

1. Good accessibility by public transport is provided when, at a walking distance of up to 350 meters between the sales unit and the stop, a service frequency of at least every 10 minutes is planned as the basic offering.

2. Multiple connections to public transport are to be assessed cumulatively.

3. For peak times, the service offering should be adjusted to meet demand.

4. If the connection to public transport is made via a local bus, the timetable must be coordinated with the higher-level public transport connections.

1. Extensions of sales units created within the framework of a district planning procedure require a corresponding amendment to the district plan.

1. The application to the municipal council to initiate a land redistribution procedure must be submitted in writing, with justification, and must specify a possible delineation of the perimeter.

1. The readjustment perimeter delineates as a readjustment area those parcels of land to which the provisions regarding land readjustment apply.

2. Where it proves to be sensible, perimeter adjustments are to be made to properties that are intersected by the readjustment perimeter.

3. If there are roads or water bodies at the edge of the readjustment area, their axes form the readjustment perimeter.

1. The reallocation perimeter must be submitted to the Office for Geoinformation for preliminary review. This office obtains the report from the Office for Spatial Planning and, if necessary, from other relevant departments.

1. Depending on the jurisdiction, the municipal council or the government council determines to the Directorate of Economic Affairs and Health and the affected landowners that the land reallocation has been decided.

2. Subsequently, the Directorate of Economic Affairs and Health issues the implementation decision to the authorities and departments interested in the land reallocation.

1. In the execution resolution, the responsible land registry office is invited to record the annotation of the participation obligation of the affected properties.

2. The Office of Geoinformation shall delete the annotation in the land register upon the request of the Implementation Commission, as soon as any objections to the cost distribution have been legally settled, and the compensation payments as well as the reallocation costs have been paid or secured.

1. The Execution Commission consists of 3-7 members, and the Valuation Commission consists of 3-5 members.

1. Competent Cantonal Authority for Actual or Legal Changes to Land in the Reallocation Area is the Office for Geoinformation.

1. The road network plan must be legally binding for the reallocation perimeter before the commencement of the reallocation work.

2. Building and road alignment plans must be legally binding before the laying out of the reallocation plan.

1. For built-up properties and those parcels of land that derive little to no benefit from the land consolidation, the deduction for public use land areas is to be appropriately reduced.

1. The area to be relinquished to the community without compensation shall generally not exceed 12% of the reallocation area.

1. If existing public traffic facilities are eliminated in the reallocation area, their land must be contributed free of charge for the benefit of the new traffic facilities.

2. Exempt from this are areas for traffic facilities that the public body has purchased. The purchase costs are to be offset against the construction costs of the new traffic facilities.

1. The work for the maintenance of official surveying may only be carried out by a licensed engineer-surveyor.

2. This particularly concerns the drafting of the reallocation plan (as per the provision mentioned below), the settlement of rights and encumbrances, the staking out and demarcation of the reallocation, as well as the preparation of the adjusted reallocation plan for approval by the government council.

1. The reallocation plan with the land and ownership register includes the depiction of the previous and new ownership circumstances.

2. With the written consent of all involved landowners and other persons with a legal interest, the posting of the reallocation plan can be waived.

3. Upon a justified request from the execution commission, the Department of Economic Affairs and Health may declare the reallocation as completed for individual plots of land following the posting procedure, provided they are not affected by objections.

1. The Decisions of the Appraisal Commission at the Time of the Presentation of the Reallocation Plan Shall Include in Particular

a. the market value of the parcels involved for over- and under-allocations,

b. the market value for compensated assignments to the community,

c. the market value for the acquisition of parcels for which there is no reallocation claim,

d. the valuation in the land readjustment according to values, and

e. the reduction for areas designated for public needs.

1. The reallocation plan to be approved is the objection-adjusted publication document. It consists only of the plan depicting the new property status (mutation plan) and the area and owner register.

2. The Government Council conducts a legal review upon approval. It specifically examines whether the land reallocation procedure was correctly carried out, whether the reallocation plan can base itself on a legally binding land use plan, and whether there is a complete clearance of rights and encumbrances.

1. Before the municipality decides on the new boundary line, it shall obtain the opinion of the Office for Geoinformation.

1. A land reallocation can be conducted or continued under private law from the outset or after the resolution for implementation.

2. The public law provisions regarding the preliminary examination procedure, the preparation of the reallocation plan, the designation of areas for public needs, the rectification of rights and encumbrances, and the legally binding land use planning must be observed.

3. If the private law agreement is not concluded, the procedure, upon request by one or more landowners, will be converted into a public law procedure by resolution of the Directorate of Economic Affairs and Health. The procedure either starts anew or continues from the last procedural step conducted under private law.

1. The following requests for mutation require approval

a. Boundary mutations of developed parcels;

b. Boundary mutations of undeveloped parcels that border a cantonal road;

c. Boundary mutations of parcels outside construction zones or of parcels that lie both within and outside a construction zone;

h. Boundary mutations of parcels affected by an intended or ongoing construction application;

i. * Privately agreed upon land reallocations;

j. * Boundary mutations of parcels with a contaminated site (Art. 5 AltlV).

2. No approval is required if the aforementioned cases involve boundary changes resulting from the transfer of land to public roads and waters or are mandated by an order from the building permit authority.

1. Mutation requests requiring approval must be submitted to the Surveying and Land Improvement Office (Office).

2. The Office invites the municipality and affected service departments to provide comments, setting a deadline for their responses.

3. The Office issues both approving and rejecting decisions.

1. The municipalities and offices that have caused a condition to be entered in the land register shall monitor the enforcement and request the deletion.

1. Where plots are accessed via annotation plots, they must have a width of at least 3 m.

2. Under special circumstances, the approving authority may grant exceptions.

1. For the calculation of building usage (building index, usage index, exploitation index according to ORL), the parcel area existing at the time the construction permit is granted is decisive, unless the municipality has provided for the transfer of usage according to § 88 RBG.

2. Parcel sections that lie within the agricultural zone or forest area may not be included in the calculation.

3. Parcel sections that lie within other zones (for example, green and shore protection zones) may be wholly or partially included in the usage calculation, provided the zoning regulations allow for it.

4. The municipal council can permit the inclusion of land ceded for roads and facilities in the usage calculation, provided it was considered in the land compensation and the zoning regulations allow for it.

1. The countable plot area (aGSF) includes the parcel areas or parts of parcels located within the corresponding building zone at the time of the granting of the building permit.

2. Parts of parcels that overlap with other zones (such as shoreline protection zones) can be wholly or partially included in the usage calculation, provided the zoning regulations allow for this.

3. The municipal council may permit the inclusion of land ceded for roads and facilities in the usage calculation, provided this was considered in the land compensation and the zoning regulations allow for it.

1. The building ratio indicates in percentage terms how much of the relevant parcel area may be built upon. For the calculation, the outer outline of the structures above the natural terrain is considered.

2. The zoning regulations specify which buildings or building components are not counted towards the built-up area.

1. The Building Coverage Ratio (BCR) is the ratio of the accountable building area (ABA) to the accountable land area.

2. The accountable building area is considered to be the area within the projected facade line.

1. The utilization ratio determines in percentage terms the relationship between the usable floor area and the relevant parcel area.

2. The zoning regulations specify which buildings or building components are not included in the usable floor area.

1. The Green Area Ratio (GZ) is the ratio of the eligible green area (aGrF) to the eligible plot area.

2. Eligible green areas are considered to be natural and/or planted ground surfaces of a property that are not sealed and do not serve as storage space.

1. The utilization ratio is the proportion between the accountable gross floor area of the buildings and the accountable plot area.

2. The accountable gross floor area is considered to be the sum of all above-ground and underground floor areas that serve and can be used for living, working, and commercial purposes. Wall and partition thicknesses are included.

3. The zoning regulations specify which buildings or building components are not counted towards the accountable gross floor area.

2. The Gross Floor Area of the Main Buildings (BGFH) includes

a. Above-ground full storey areas, including perimeter walls;

b. All attic floor areas, regardless of use (including walls, stairs, corridors, etc.), which have a height of at least 2.30 m from the upper edge of the attic floor to the lower edge of the roof structure and a width of more than 2.00 m within the roof profile;

c. Basement areas, including associated partition and perimeter walls, stairs, and accesses, which meet the residential hygiene requirements regardless of use (10% window area, 2.30 m room height);

d. Areas of unheated intermediate climate spaces such as glazed balconies, conservatories, vestibules, and similar.

3. The Gross Floor Area of the Main Buildings (BGFH) does not include

a. At least one-sided open, covered, or uncovered balconies;

b. At least one-sided open, covered entrance areas and seating areas.

1. If a building plot is located in different zones, the architectural utilization must be determined separately.

2. For developments that appropriately reflect the character of the various zones, the municipal council may allow the consolidation of the utilization in one building structure, provided that the zoning regulations permit it.

1. If multiple buildings are erected on a parcel that is to be subsequently subdivided (standard construction method, exception development according to a unified plan, neighborhood plan), the structural utilization must be maintained in its entirety.

2. If underutilized individual parcels arise from a subsequent subdivision, the permitting authority must ensure that corresponding construction restrictions are recorded in the land register for these parcels.

3. If the structural utilization is increased within the framework of zoning regulations, the municipal council, upon application by the property owner and in agreement with the construction permitting authority, must review whether the construction restrictions should be lifted.

1. The boundary distance is determined by the polygon formed using all boundary distances.

2. Relevant for the calculation of the boundary distance are the lengths of the facades and the number of stories. Regardless of the building profiles specified in the zoning regulations of the municipality, a facade height of up to 4.5 m is considered single-story for the measurement of the boundary distance. An additional 3.5 m is added for each further story (see the concordance table below for the calculation of the boundary distance; GZ = Number of Stories, FH = Facade Height, FL = Facade Length)

| | GZ 1 | GZ 2 | GZ 3 | GZ 4 | GZ 5 |

| --- | --- | --- | --- | --- | --- |

| | FH up to 4.5 m | FH 4.5-8 m | FH 8-11.5 m | FH 11.5-15 m | FH 15-18.5 m |

| FL up to 6 m | 2.0 | 2.5 | 3.0 | 3.5 | 4.0 |

| FL over 6-12 m | 2.5 | 3.0 | 4.0 | 5.0 | 6.0 |

| FL over 12-24 m | 3.0 | 4.0 | 5.5 | 7.0 | 8.5 |

| FL over 24-36 m | 3.0 | 5.0 | 7.0 | 9.0 | 11.0 |

3. The facade height relevant for the boundary distance is measured from the intersection point of the facade with the lowest point of the natural terrain to the intersection point of the facade with the upper edge of the rafters (raw measurement).

a. * Gable triangles taller than 6 m (intersection of the facade with the upper edge of rafters to the ridge upper edge of rafters) are added to the facade height by half their height.

b. * If the roof slope on the eaves side is more than 60°, the facade for gable roofs is measured up to the ridge and for mansard roofs up to the middle ridge.

c. * Facade recesses are not considered if the recess is not at least 4.00 m long or one-fourth of the facade length.

4. If the building body is

a. * stepped in height and/or offset in depth, or

b. * kinked by at least 20° in the building line,

5. For round buildings or round facade parts, the boundary distance is measured analogously to the table according to paragraph 2. Instead of the facade length, the chord length applies (see appendices).

6. In the case of atypical facades, the building permit authority determines the boundary distance.

3. The height relevant for the boundary distance is measured from the intersection point of the facade with the lowest point of the relevant terrain to the intersection point of the facade with the top edge of the rafters (raw measurement).

a. Gable triangles taller than 6 meters (from the intersection point of the facade with the top edge of the rafters to the ridge top edge of the rafters) are counted towards the height by half of their height.

b. If the roof pitch at the eaves side exceeds 60°, the facade is fully counted up to the ridge for gable roofs and up to the middle ridge for mansard roofs.

c. Facade recesses are not considered unless the recess is at least 4.00 meters long or accounts for 1/4 of the facade length.

1. The building length is the longer side of the rectangle with the smallest area that encompasses the projected facade line.

1. The building width is the shorter side of the smallest rectangle by area that encompasses the projected façade line.

1. Building Height: The building height is the greatest height difference between the intersection line of the gable-sided facade alignment with the top edge of the roof structure and the corresponding facade line.

1. The knee wall height is the height difference between the top edge of the unfinished attic floor and the intersection line of the facade alignment with the top edge of the roof structure.

1. The clear height is the vertical distance between the top edge of the finished floor and the bottom edge of the finished ceiling or beam layer, when the usability of a story is determined by the beam layer.

1. Full stories are all floors of buildings except basement, attic, and penthouse floors.

2. In the case of attached buildings and buildings that are tiered in height or position, the number of full stories is determined separately for each building part or for each building.

1. Basements are floors where the upper edge of the finished floor, measured along the facade line, projects above the permissible level over the facade line on average to a limited extent. The average is determined by the mean of the maximum basement heights for each facade line above the relevant terrain.

2. Basements may, unless otherwise provided by the municipality, project a maximum of 1.20 meters in hillside locations and a maximum of 80 centimeters on flat terrain above the applicable or lowered terrain.

3. Unless otherwise provided by the municipality, the length of an excavation may not exceed one-third of the total length of the projected facade line and may not be deeper than 1 meter.

1. Attic floors are the stories whose knee wall heights do not exceed the permissible measure of 1.20 meters.

1. Penthouse floors are additional floors constructed on flat roofs. Unless otherwise stipulated by the municipality, the penthouse floor must be set back by at least 3 meters from the floor below on at least one entire facade and may cover a maximum of 50% of the area of the floor below.

1. The facade height is the greatest height difference between the intersection line of the facade alignment with the top edge of the roof structure and the corresponding facade line.

1. The following structural elements may project from façades that meet the minimum boundary distance to neighboring parcels

a. Main and front roofs up to 1 m,

b. Open balconies, provided they constitute less than 1/3 of the façade length, up to 1.00 m,

c. Other structural elements up to 0.50 m.[16]

2. The following may project over building lines and statutory distances up to 1.50 m

Main roofs, front roofs, and open, continuous balconies. Other structural elements may project from the façade only up to 0.50 m.[17]

3. When building and street lines coincide, main roofs, front roofs, and balconies must have a clear height of 2.50 m above the sidewalk level and a distance of at least 0.50 m from the sidewalk edge. Other structural elements may project from the façade only up to 0.20 m.[18]

4. When building and street lines coincide and there is no sidewalk present, all structural elements projecting from the façade must maintain a clear height of 4.50 m.

1. The building frontage line is the vertical plane formed by vertical lines through the outermost points of the building structure above the reference terrain: projecting and insignificantly recessed parts of the building are not taken into account.

1. The facade line is the intersection line of the facade alignment and the relevant terrain.

1. The projected facade line is the projection of the facade line onto the plane of the official survey.

1. Between the building and street line or within the statutory distance from traffic areas, the following may be erected

a. Facilities for energy and water supply as well as telecommunications,

b. Bicycle shelters of lightweight construction,

c. Open-sided carports,

d. Windbreaks up to 4 square meters of floor area,

e. Pergolas.

2. In core zones, only facilities for energy and water supply as well as telecommunications are permitted.

1. The owners of properties are required to tolerate the installation of street signs, facilities for public lighting, hydrant and valve signs, hydrants, fittings for public pipelines, electric distribution boxes NE7, survey control points, and similar facilities necessary for public interest.

2. The regulations concerning statutory distances and building lines do not apply to public facilities.

1. Single-story ancillary structures such as garages, sheds, and other small constructions may be placed arbitrarily close to a main building on the same parcel or, with the written consent of the neighbor, arbitrarily close to the boundary if

a. the structure is not connected to a main building,

b. the structure does not serve residential purposes,

c. the floor area does not exceed 36 m² for garages or 20 m² for other ancillary structures,

d. the facade height of the building wall facing the main building or neighboring property does not exceed 2.5 m.

2. If a neighbor consents to an ancillary structure with a reduced boundary distance, they simultaneously acquire the right to construct a comparable structure with the same boundary distance on the opposite side of their parcel.

3. For ancillary structures under this provision that have been demonstrably in place without the neighbor's consent and unchallenged for at least 3 years, the consent is considered tacitly granted. This also applies to other constructions requiring consent, such as retaining walls, foundations, excavations, and embankments (§ 92 Para. 1 and 2, § 93 Para. 1 RBG).

4. The boundary distance for swimming pools must not be less than 2 m without the written consent of the neighboring party.

1. Small structures are standalone buildings that do not exceed permissible dimensions and contain only ancillary use areas.

2. Extensions are built together with another building, do not exceed permissible dimensions, and contain only ancillary use areas.

3. Single-story small structures such as garages, sheds, and others may be placed at any proximity to a main building on the same parcel or with the written consent of the neighbor at any proximity to the boundary, provided that
