Even for industries too, the selection of site is very important. Besides the fact that sufficient water and electricity should be available , the Vaastu of the plot, such as the shape of the plot, the roads facing the plot and the ground level inside and outside the site are very important.

The various principles of Vaastu which aid in setting up an industry are as follows:
1. Main roads towards east, north or north-east are advisable with wide gates on two sides.
2. Gates in north-east or east or north-west are recommended.
3. Guard room should be either on north-west side of north-gate or south-east side of east gate.
4. Minimum space should be kept in south and west where big trees could be grown. More open space should be left in north and east where lawns and other greenery can be grown.
5. The floor levels in south-west must be higher than other sides and height of the building also must be higher than all the other corners. Care has to be taken to have the store rooms in south-west fully loaded with stocks to the extend possible.As and when the stocks are consumed they should be replaced immediately.
6. Car parking may be provided in north-west if open area is available. For light vehicles north-east could also be used.
7. Administrative offices are to be located either in north or east, away from boundry walls with less height than the main factory. Here special care has to be taken in keep int north-east corner open.
8. Staff quarters may be constructed in south-east and north-west. If quarters are multi-storeyed and if the height is more than of main factory, they should be constructed in south-west without touching the main premises.
9. Toilets should be places in north-west or south-eastern part of the buildings, and not in north-east or south-west.
10. Wells, bore wells water pumps and water ponds etc. should be in the north-eastern area.
11. Over head tanks may be erected in west and nearby, duly maintaining the heights. South-west and north-east sides including north and east should be avoided, for constructing overhead tanks. This is a bit controversial subject and hence one should be very careful in locating the overhead tanks and also the water tanks above the ground level.
12. Heavy machinery has to be installed in south, west or south-west in the factory.
13. Raw materials storage, whether inside the factory or sheds outside, should be in south or west or south-west.
14. Finished products are to be kept in the north-west corner. It will help for quick movements of the stocks.
15. Products under process or unfinished goods may be kept in west direction.
16. Weighing machine may be located near the gate either in north or east because that area is not
subjected to permanent weight.
17. Transformers, generators, motors, boilers, furnaces, oil engines should be kept in south-east or close to south-east.
