Yes, it is generally acceptable to take a tape measure with you during a house viewing. Bringing a tape measure can be useful for measuring room dimensions, doorways, or other spaces to ensure that your furniture and belongings will fit comfortably in the property. It can also help you assess the feasibility of any planned renovations or modifications.
However, it’s always a good idea to obtain permission from the homeowner or estate agent before taking measurements. Additionally, be respectful of the property and avoid causing any damage or inconvenience while measuring. Taking accurate measurements can provide valuable information for your decision-making process when considering a property.
