Sorry, it's 15%. Your lawyer should have sent you the necessary information when the condo has TOP and is ready for key collection.
What should I do when there are defects in my new home?
You may follow the steps below, which are based on the terms in the S & P agreement:-
Step 1:
Give advance written notice to the developer highlighting specific details of the defect(s). If no response is received by one month from the date of notice, proceed to Steps 2a and 3a. (The notice can be in various forms e.g. developer-issued inspection form for reporting defects, letters, etc)
Step 2:
Make arrangements with the developer to either conduct a joint inspection of the defect, or fix an appointment for the developer to carry out necessary repairs if the inspection is not necessary. (Please note that to agree on a suitable time for repairs to be carried out, coordination by both parties is required.)
Step 3:
After an appointment has been fixed, contribute by helping to ensure that the area for repair has been cleared, to facilitate the smooth completion of work. (This will help prevent damage to your furnishings and belongings while repairs are being carried out.)
Step 4:
At the appointed day and time, make sure that someone is in the premises to grant access to the workmen to carry out rectification works.
Step 5:
Acknowledge to confirm that repairs have been carried out. (This will help all parties to account for the status of the work and prevent any complications that may arise. Additional defects may be dealt with in the same manner as described above)
What if there is no response from developer?
Step 2a:
Issue written notice to the developer of your intention (Notice of Intent) to rectify the defects and also provide the estimated cost of such work.
Step 3a:
You may commence your own rectification works if the developer does not carry out the work within 14 days from the date of notice, and recover the cost from the developer. The cost may be deducted from the sum held by the Singapore Academy of Law as stakeholder for the developer.
