Why is it odan için and not odanın için?
Odan means 'your room' (oda + -n). The postposition için (for) directly follows regular nouns and possessive nouns without needing an extra genitive case (the 'of' ending). You only need that extra ending before için when using standalone pronouns (like senin için - for you). Since odan is a noun, odan için is all you need.
