Offences Against Property
(1) Entering another's property intending to commit an offence or to intimidate/insult/annoy its possessor, or unlawfully remaining after lawful entry with such intent, is "criminal trespass". (2) Criminal trespass by entering/remaining in a human dwelling, place of worship, or property-custody building/tent/vessel is "house-trespass" (even partial bodily entry counts). (3)-(4) Criminal trespass is punished with up to 3 months' imprisonment, up to ₹5,000 fine, or both; house-trespass with up to 1 year's imprisonment, up to ₹5,000 fine, or both.
This defines the foundational trespass offence - entering property with a bad intent (not just entering without permission) - with an enhanced penalty specifically when the trespassed property is a home, place of worship, or property-storage building.
Entering someone's home without permission specifically to intimidate or harass them, even without stealing anything, meets this section's definition of house-trespass.
