Guidance for using laser rangefinders in measuring house area
When we buy a house, the sales staff will tell the buyer the area of the house; After applying for the property certificate, another property area will be written on the certificate. So, how were these areas measured?
It is understood that the area measurement of commercial housing is carried out in two stages. Firstly, surveyors measure the predicted area of the house based on drawings and other data; After the completion of the house, the area measurement must begin. During the area measurement phase, surveyors need to conduct household measurements using advanced equipment such as laser rangefinders to measure the length, width, and height of the house. Based on this data, the interior area of the house is calculated, and the area of shared buildings such as staircases and elevators is measured.
Experts analyze that many citizens equate the interior area of a property with the usable area, but there is actually a difference between the two. "The area inside the house is larger than the usable area because the area inside the house is half the area of a wall, and half of the area of the neighbor's common wall, which needs to be included in the usable area." After purchasing a house, some citizens often use tools such as a tape measure to measure the usable area of the house, and obtain area data to compare with the data on the property certificate. The staff stated that when citizens use a tape measure to measure, there are often errors in the measured data due to factors such as usage methods and the tightness of the tape measure. Moreover, this only measures the area used, not the area inside the set.
So, what if there are any objections to the surveying results of one's own house? Surveyors have stated that citizens can first apply for retesting. Laser rangefinders can accurately measure all areas, and if there are any objections, they can apply for administrative reconsideration.
