对，只能出租房间。记得通知HDB， 还有报税。Renting out EC rooms No prior approval from HDB is required if you rent out your bedroom(s) in the EC within the MOP. However, with effect from 1 Feb 2010, you must register the subletting of bedrooms with HDB within 7 days of doing so. You are also required to notify HDB when you renew or terminate the subletting of bedrooms, and when there are changes to your subtenants’ particulars. You may approach the HDB Branch managing your EC to register the subletting. http://www.hdb.gov.sg/fi10/fi10321p.nsf/w/BuyingNewFlatECConditionsafterPurchase?OpenDocument
