What is the difference between a building line and a building line?

The property line consists of the right of way and the building control line. The red line of the road is the planning control line of the land used for urban roads (including residential roads); The building control line is the control line at the base of the building. On the side adjacent to the road, the red line of the road is generally used as the building control line, and if it is necessary for urban planning, the competent authority may set a building control line in addition to the road line, which is generally called the construction of the setback road red line.

No building may exceed a given building line. The General Principles for the Design of Civil Buildings (JGJ37-87) stipulates that the steps, platforms, window shafts, underground buildings and building foundations of buildings, except for the urban pipelines connected to the base, are not allowed to protrude from the red line of the road. Architectural protrusions that allow protrusion of the right line of the road:

1. Over the pavement ground: (1) Window sashes and window covers are allowed to protrude above 2 meters, and the protrusion width is not more than 0 4 meters; (2) 2 More than 50 meters are allowed to protrude movable sunshade, and the protruding width should not be greater than the width of the sidewalk minus 1 meter, and should not be greater than 3 meters; (3) 3 More than 50 meters are allowed to protrude balconies, convex windows, canopies, eaves, and the protruding width should not be greater than 1 meter; (4) More than 5 meters are allowed to protrude the canopy and eaves, and the protruding width should not be greater than the width of the sidewalk by 1 meter, and not more than 3 meters. 2 Over a road with no sidewalk:

1) 2 More than 50 meters are allowed to protrude window sashes and window covers, and the protrusion width should not be greater than 0 4 meters; (2) More than 5 meters are allowed to protrude canopies and eaves, and the protruding width should not be greater than 1 meter.

The urban green line refers to the control line of various types of urban green space.

The urban blue line refers to the territorial boundaries for the protection and control of urban surface water bodies such as rivers, rivers, lakes, reservoirs, canals and wetlands determined by urban planning.

The high-voltage corridor refers to the special passage between two parallel lines formed by the conductors on both sides of the high-voltage overhead power line of 35kV and above extending to the outside for a certain distance under the condition of calculating the maximum wind deviation and safety distance of the conductor.

There is no difference, the building line is also called the "building control line", which is the control line of the base position of the building, that is, the building red line.

Three red lines of construction:

1.The red line of the road is the planning control line of the land used for urban roads (including residential roads);

The outermost line on both sides of the road.

2.The land use red line is the planning control line of the land use range.

The outermost boundary line of a building and its greenery, roads, etc.

3.The building line, generally known as the building control line, is the control line at the location of the building's base.

The outermost edge of the building touching the ground.

The building red line, also known as the building control line, is the boundary line that controls the street surface of buildings or structures (such as exterior walls, steps, etc.) on both sides of the urban road in urban planning and management.

The property line generally consists of a road line and a building control line. The red line of the road is the planning control line of the land used for urban roads (including residential roads), and the building control line is the control line of the base position of the building. The base is adjacent to the road, and the red line of the road is generally used as the building control line.

If due to the needs of urban planning, the competent authority may set a building control line in addition to the road line, which is generally called the setback road red line. The building line can coincide with the road line, and generally in new cities, the building line is often retreated behind the road line, so as to free up land, improve or beautify the environment, and achieve good results.

The red line of land use is a line that connects some coordinate points around a certain plot, and the land area within the red line is the scope of land used to obtain the right to use. When developing and constructing the building community of this plot, it is also necessary to set back the red line by about 2 meters, which varies from place to place, depending on the regulations of the local planning bureau. The buildings of the community must be within the red line, and the land that has been withdrawn is not allowed to be occupied.

The red line of the site is only marked on the red line map, and it cannot be seen on the site. However, the setback line is clear at a glance, and the wall of the community is the setback line.

Legal basis

Construction Law of the People's Republic of China

Article 41 Construction enterprises shall abide by the provisions of laws and regulations on environmental protection and production safety, and take measures to control and deal with the pollution and harm to the environment caused by all kinds of dust, waste gas, waste water, solid waste, noise and vibration on the construction site. Article 42 In any of the following circumstances, the construction unit shall go through the application and approval procedures in accordance with the relevant provisions of the State:

1) It is necessary to temporarily occupy a site outside the scope of planning approval;

2) It may damage public facilities such as roads, pipelines, electricity, posts and telecommunications;

3) It is necessary to temporarily cut off water, electricity, or road traffic;

4) It is necessary to carry out blasting operations;

5) Other circumstances where laws and regulations provide that it is necessary to go through approval formalities.

Also known as the "building control line", it refers to the boundary line that controls the street surface of buildings or structures (such as exterior walls and steps) on both sides of the urban road in urban planning and management. No building or structure facing the street shall exceed the building line.

The property line is the maximum building area.

When the investor obtains the development right of a certain piece of land, the relevant leading department will give a red line for the construction, which means that the building built by the investor shall not exceed this range. Some civil buildings, such as residential areas, will build fences along the red line of the building, and the walls can be planned according to the designer's design, such as the construction of a square, then set up steps or greening along the red line of the building.

However, if a free-standing building is constructed, it is generally not built against the building line. This is to ensure that there is sufficient spacing between the buildings to allow for basic facilities such as walking, lighting, safe passage, etc.

1. Their planning scope is different.

Planning lines are defined in the same way as building lines, and perimeter lines are the planning lines used along the walls.

2. The colors they represent are different.

The building line and planning line are red lines, and the fence lines are black lines.

3. The types of threads they use are different.

The building line and the planning line are single-point and single-dash lines, and the fence line is a dashed line.

Building lines, building control lines.

The building red line, also known as the "building control line", refers to the boundary that controls the frontage of buildings or structures (such as exterior walls, steps, etc.) along both sides of the urban road in urban planning and management, and is also the boundary that the façade of the building cannot exceed. No building or structure facing the street shall exceed the building line.

The planning line is also known as the building line.

The red line generally refers to the boundary line of various land uses. Sometimes a building line that determines the location of buildings along the street is also called a red line, that is, a building red line.

The boundary line of the planned urban road width reflects the width of the road line, which includes: the width of the road required for the passage of motor or non-motor vehicle and pedestrian traffic; The increased width required to lay underground and above-ground pipelines and urban utilities.

Fence line: The fence line is drawn according to the design needs, not limited by planning conditions, and is reasonable.
