Metal Hall Legalisation in Bulgaria – Building Permits and Required Documents

The procedure for obtaining the necessary permits and documentation for a relocatable metal hall depends on the structure’s technical specifications, dimensions and intended use. Halls can be constructed using various materials, including metal sheeting, PVC membranes, rigid PVC panels and sandwich panels.

Before planning a relocatable hall, it is essential to establish whether the structure is classified as a building or qualifies as a movable structure under Bulgaria’s Spatial Development Act (SDA).

Global RTS offers a range of mobile and relocatable structures for sale and rental, designed in accordance with applicable regulations and safety requirements.

Metal Hall Legalisation in Bulgaria – Permanent or Movable Structure?

Determining the legal classification of a hall under the Bulgarian Spatial Development Act (ЗУТ) is the first step in planning a project.

Each structure must be assessed to establish whether it qualifies as a building or meets the legal requirements for a movable structure. This assessment considers the structural design, intended use and connection to the ground.

Movable Structures under Article 56 of the Spatial Development Act

To qualify under Article 56, both the structural characteristics and the intended purpose of the facility must be assessed.

The ability to dismantle and relocate a structure, or the type of anchoring used, does not automatically establish its status as a movable structure.

A placement permit is issued in accordance with the applicable municipal procedures.

Category IV and V Buildings under the Spatial Development Act

When a metal hall or another type of industrial structure requires substantial reinforced concrete foundations and is intended for permanent use, it is generally treated as a conventional building.

In such cases, the full building permit procedure applies, including the preparation and approval of an investment design.

Key Differences Between Movable Structures and Buildings

Feature	Movable structure (Article 56)	Building (Category IV/V)
Main permit	Placement permit	Building permit
Ground connection	Without reinforced concrete foundations	Requires reinforced concrete foundations
Approval timeframe	As short as possible, subject to municipal procedures	Typically 1–3 months
Flexibility	Can be dismantled and relocated	Intended for permanent installation
Main documentation	Structural assessment and architectural placement plan	Complete investment design documentation

Building Permits for Industrial Halls in Bulgaria – Required Procedures

When a building permit for an industrial hall is required, the investor must complete several administrative steps.

1. Obtaining a Cadastral Sketch and Design Visa

The process begins with obtaining an up-to-date cadastral sketch of the property from the Agency for Geodesy, Cartography and Cadastre.

An application is then submitted to the municipality’s Chief Architect for a design visa, which establishes the permitted development parameters for the property.

2. Preparing the Design Documentation

The investment design for a mobile or metal hall includes the documentation required for its specific purpose, structural system and equipment.

The following list is indicative and does not cover every requirement applicable to individual projects.

• Architectural design: Floor plans, elevations and cross-sections of the structure.

• Structural design: Detailed structural calculations for all load-bearing elements, including stability assessments and wind and snow load calculations based on the location.

• Fire safety: Fire risk assessment and provision of appropriate evacuation routes.

• Health and Safety Plan: Organisation of installation and construction activities in accordance with applicable safety requirements.

3. Design Approval and Building Permit Issuance

The project documentation undergoes the necessary consultations and compliance assessments under the applicable procedures.

It is then submitted for approval and the issuance of a building permit by the municipality’s Chief Architect.

Industrial Halls for Sale and Rental from Global RTS

Global RTS offers both professional industrial halls and economical EasyStore halls for sale and rental.

Our structures are designed to meet applicable construction and safety requirements. We also provide professional installation, dismantling and maintenance services.

How to Build a Relocatable Industrial Hall – Documentation and Project Stages

Building a metal hall or a mobile structure with PVC membranes, insulated sandwich panels or rigid PVC panels requires coordination between administrative preparation and technical implementation.

Preparing the correct documentation helps avoid delays during construction and reduces the risk of interruptions by regulatory authorities.

Required Documents for Industrial Hall Construction

• Proof of property ownership, established building rights or another applicable legal basis for construction on the site.

• Design visa or an approved placement plan issued by the Chief Architect.

• Required architectural and engineering design documentation.

• Structural engineering design, including load-bearing capacity and stability calculations.

• Fire safety assessment confirming compliance with applicable requirements.

• Agreements with utility providers for electricity, water supply and wastewater connections, where applicable.

• Decision or official opinion from the Regional Inspectorate of Environment and Water concerning the need for an Environmental Impact Assessment (EIA), where applicable.

Our completed prefabricated industrial hall project in Veliko Tarnovo is an example of a structure delivered following project planning and preparation.

For similar applications, clients can also choose our arched industrial halls, which provide generous interior volume and covered space according to the selected dimensions and configuration.

Planning a Relocatable Hall – Structural Design and Technical Documentation

Every technical design for a metal or relocatable hall requires careful consideration of structural elements, height specifications and cladding materials.

Load-bearing structures made from aluminium profiles offer relatively low structural weight, with technical performance determined by the selected system and project requirements.

Cladding and roofing options can be adapted to the intended application, ranging from PVC membranes and sandwich panels to metal sheeting and glazed façades.

Key Engineering Parameters

• Wind and snow loads: Structural calculations are prepared according to the location of the facility and the relevant climatic conditions in Bulgaria.

• Anchoring system: Depending on the site and structural requirements, anchoring options include bolts for concrete foundations or specialised ground anchors for installation on suitable existing surfaces, such as asphalt or levelled gravel.

• Functional layout: Planning the positioning of industrial doors, pedestrian access points, lighting and ventilation systems according to operational requirements.

Standard and Custom-Designed Industrial Halls

Global RTS offers a wide range of standard industrial structures for sale and rental.

For projects requiring non-standard dimensions or configurations, our engineering department can prepare a custom design tailored to the client’s requirements.

Frequently Asked Questions

Can an Existing Metal Hall Built Without Permits Be Legalised?

Not every metal hall constructed without the required documentation can be legalised.

The assessment depends on the year of construction, the legal classification of the structure and its compliance with applicable regulations.

For certain structures built before 31 March 2001, Bulgaria’s legal tolerance provisions may apply, provided the relevant conditions are met.

A certificate of tolerance is not equivalent to formal legalisation.

How Long Does It Take to Obtain a Placement Permit under Article 56?

The processing period depends on the municipality and the specific administrative procedure.

The overall timeframe also depends on the required documentation, consultations and any additional information requested by the authorities.

The Global RTS team assists with structural assessments and the preparation of technical documentation to help complete the process within the shortest possible timeframe.

What Is the Difference in Documentation When Purchasing or Renting a Hall?

When purchasing a hall, the investor receives the relevant engineering and structural documentation required for long-term operation or for obtaining approval as a permanent structure, where applicable.

When renting a mobile hall, Global RTS provides the necessary safety certificates and technical assessments to support the tenant’s application for a placement permit covering the rental period.
