Another point to note will be that food factories usually command a premium in terms of rental rates or sale prices. This may be due to the approved use of the premises and may also be due the demand for food factories in Singapore. Hence, a B2 factory with much lower rental rate or sale price as compared to a B2 food factory is quite unlikely to be a B2 approved food factory and may instead be a B2 general industrial space.
Of course, proper due diligence is advisable to be done in order to determine whether it is a B2 general industrial factory or a B2 approved food factory as there are also various factors such as remaining tenure, location and specifications which may affect the prices.
