Converting a building to a new use? Asbestos requirements change with occupancy.
When a building changes use, warehouse to offices, factory to apartments, school to community centre, the asbestos requirements often change too. Different occupancy types have different exposure thresholds, ventilation requirements, and management obligations.
A change of use typically triggers the need for a comprehensive asbestos survey even if one was previously done for the original use. Materials that were acceptable to leave in place in an unoccupied warehouse may need removal when the building becomes a residential or public space.
The planning and building permit process for change of use usually requires documentation of asbestos status. Failing to address asbestos before conversion can result in permit refusal, project delays, and future liability.
The Problem
Converting buildings to office use, whether from residential, retail, or industrial, introduces employee occupancy standards that require asbestos to be managed to workplace health regulations. The building's existing asbestos status may be inadequate for the new use.
Office conversions typically involve extensive interior works, new partitions, raised floors, suspended ceilings, and IT infrastructure, all of which may disturb existing asbestos materials. A pre-conversion survey is essential to plan the works safely and budget accurately for any removal needed.
What You Need
Frequently Asked Questions
Is an asbestos survey needed before changing a building's use?
Yes, any change of use that involves refurbishment work requires a refurbishment asbestos survey beforehand. The change in occupancy profile may also trigger new management obligations under asbestos regulations.
How much does a full asbestos survey cost?
A full management survey typically costs between €350-€1,200 (£300-£1,000) depending on property size and complexity. Refurbishment/demolition surveys cost more due to their intrusive nature, typically €600-€3,000. Prices vary significantly by country and surveyor.
Do I need an asbestos survey before changing the use of a building?
Yes. A change of use often triggers regulatory requirements for an asbestos assessment, particularly when converting commercial or industrial premises to residential use. The survey identifies any ACMs that may need management or removal before the new use begins.
Which type of asbestos is used for commercial purposes?
Chrysotile (white asbestos) was the most widely used commercially, found in cement products, brake linings, and textiles. Amosite (brown) and crocidolite (blue) were used in insulation and fireproofing applications.
Is a little bit of asbestos ok?
There is no officially recognised safe level of asbestos exposure. While the risk from a single brief exposure is very low, UK regulations under CAR 2012 require that all exposure be kept as low as reasonably practicable.
