3 - Years Restriction Period on Removal of Toilet Floorand Wall Tiles Provided by HDB

The toilets in your flat come with wall and floor tiles. As the toiletsare designed to be wet areas, a waterproofing membrane has beenlaid on the cement screed before laying the floor tiles. This is toprevent water from leaking through the ceiling of the flatimmediately below your flat.

Hence, flat owners are not allowed to replace the toilet floor and walltiles provided by HDB for a period of 3 years. Flat owners may howeverlay new toilet floor finishes over the existing floor finishes usingadhesives.

Previously, this 3-year restriction period commenced from the dateof key collection. From 1 April 2005, the 3-year restriction period willcommence from the completion date of the block. This relaxation willallow flat owners greater flexibility to blend in their renovation workswith the interior decor of their flats.

on Household Shelters

The store/pantry in your HDB flat is designed and constructed to also serveas a civil defence shelter in times of emergency. Specially designed andwell-prepared to protect you and your loved ones in an emergency, thestore/pantry has strengthened walls, floor and ceiling and a steel door whichlooks like a normal household door.

Like the other structural components of the flat, the reinforced walls, floortiles, ceiling and steel door of the store/pantry cannot be hacked or drilledduring any renovation works.

Certain finishes and fixtures are not permitted as they are not easilyremovable before an emergency and may instead become hazards tooccupants sheltering inside during the emergency. Lighting, power point,telephone point and MATV outlet are also provided within the shelter so thatyou can stay inside and yet be able to communicate with the outside.

Frequently Asked Questions on Renovation work

You should check whether the renovation item requires a renovation permit and if so, applyfor it before you commence on the renovation works. You can refer to the informationguidebook on "Renovation Guide For Your HDB Flat" or renovation guides at the HDBInfoWEB at www.hdb.gov.sg.

If the works require a renovation permit, you have to authorise your registered renovationcontractors to submit your renovation application on your behalf. Your registered renovationcontractor will need to submit the application for renovation permit electronically.

If the renovation work involves the removal or repositioning of fittings, demolition orconstruction of walls, the scanning of layout plans, elevations, sections or details of theproposed work may be required.The layout plan can be purchased via HDB InfoWEBusing the “Purchase of Residential Floor Plan” e-Service or from the “Sale of ArchitecturalPlan” counter at 3rd Storey Atrium (next to payment counter), HDB Hub 480 Lorong 6 ToaPayoh Singapore 310480, or using the self service kiosk at any HDB Branch Office.

You can carry out renovation work which does not affect the structural stability of your flat.Examples of permitted renovation work are:• Laying of ceramic/homogeneous/terrazzo/marble/parquet or other tiles as floor

finishes.• Laying of additional wall tiles up to ceiling height.• Construction of kitchen cabinet base with cement mortar.• Installation of grilles in windows or at balcony openings.• Installation of cornices.

For more details, as well as for works requiring renovation permit, please refer to theinformation guidebook on ‘Renovation Guide For Your HDB Flat'. Alternatively, you canalso visit the HDB InfoWEB at www.hdb.gov.sg.

Contractors not registered with HDB are not allowed to carry out any renovation works inHDB flats. Therefore, you must not sign any contract with any contractor not registeredwith HDB to renovate your flat.

Since flat owners need not apply renovation permit for certainrenovation items, why can't flat owners engage contractors who arenot registered with HDB to carry out these works?Although a renovation permit is no longer required, flat owners are still required to engageHDB registered renovation contractors to carry out the renovation works and comply with theguidelines and conditions governing the respective renovation items. There is a need forHDB to regulate the activities of the renovation contractors within HDB estates to ensure thestructural integrity of HDB buildings, a safe living environment and minimal unsightlyalteration to the form of HDB buildings when carrying out renovation works in HDB flats.
