Which part of the hdb website can i find it? currently http://www.hdb.gov.sg/fi10/fi10324p.nsf/w/HomeRenoGuidelinesBuilding?OpenDocument#3year only mention about toilet 3-year restriction period on removal of toilets wall and floor tiles provided by HDB The toilets in your flat come with wall and floor tiles. As the toilets are designed to be wet areas, a waterproofing membrane has been laid on the cement screed before laying the floor tiles. This is to prevent water from leaking through the ceiling of the flat immediately below your flat. Hence, flat owners are not allowed to replace the toilet floor and wall tiles provided by HDB for a period of 3 years. Flat owners may however lay new toilet floor finishes over the existing floor finishes using adhesives. The 3-year restriction period will commence from the completion date of the block to allow flat owners greater flexibility to blend in their renovation works with the interior decor of their flats. The Kitchen part is just about type of reno you can do.
