Buy it from HDB's Purchase of Residential Floor Plan e-Service at services2.hdb.gov.sg. It costs S$5 per plan including GST, takes a Visa or MasterCard, and is open to the public, not only to the owner. If the plan is available it downloads straight after payment; otherwise HDB emails it within 3 working days. Check your own records first: you may already have one.
This is the procedural page. For what the plan actually shows, what it can be used for and where it falls short, see HDB floor plan purchase.
Every figure below comes from HDB's own get help page (last updated 27 August 2026) and terms and conditions (last updated 10 September 2026), both read on 2 October 2026. HDB says it may revise its fees, and the e-Service shows you the current fee before you pay, so the screen in front of you outranks this page.
Step 0: check whether you already have it
This step is free, and for a good share of readers it ends the exercise. Before opening any payment page, look in four places:
- Your Sales Brochure. If you bought the flat new from HDB, HDB's renovation permit page says you can use the floor plan in the Sales Brochure given to you at flat selection. If you are the original owner, it may be in the folder you have not opened since.
- The HDB Flat Portal and your key collection documents. Third-party sources say buyers of new flats can download their unit's plan free through the portal during the purchase stage, and that a hardcopy is handed over at key collection. We could not find either on an HDB page, so treat them as worth checking rather than as guarantees: log in, go through the key collection folder, and look before you pay.
- Your conveyancing file. The lawyer who acted on the purchase frequently holds a copy in the completion pack.
- Your property agent, or the previous owner. Both are cheaper to ask than HDB is to pay.
Step 1: get these ready
HDB's get help page lists what the e-Service asks for: the purchaser's name, a contact number, the address of each floor plan you want, an email address, and a credit card number, Visa or MasterCard. That list does not mention Singpass. Have the exact block, street and unit number in front of you rather than working from memory, and type the email address carefully: HDB gives no refund when the address or email you entered was wrong.
You do not need to be the owner. HDB describes the service as one that "allows the public to purchase the floor plans" of existing HDB flats, so a buyer doing due diligence, a tenant or a contractor can buy the plan as readily as the owner can. The service runs 24 hours a day, apart from maintenance, and works from overseas provided you give a local contact number and a valid email address.
Step 2: open the e-Service
The service is called Purchase of Residential Floor Plan, and it lives at services2.hdb.gov.sg. HDB's get help page is explicit that "The Residential Unit Floor Plan is only available online through the e-Service." HDB's renovation permit page separately mentions buying one at a self-service kiosk at any HDB Branch, but the online route is the one HDB's floor plan pages describe.
Step 3: select the flat and the plans
Enter the address and select the plan or plans you want. HDB caps each application at 5 plans; if you need more, submit another application once the previous one is complete. Managing agents and estate managers buying in volume should plan around that limit rather than discover it at checkout.
Step 4: pay
The fee is S$5 per unit floor plan, inclusive of GST, payable by credit card, Visa or MasterCard. HDB notes that it may revise its fees, so read the figure on the screen before you confirm. Once paid, the fee is not refunded except case by case: a claim must reach HDB within 2 weeks of payment, quoting the reference number, and there is no refund at all if the address or email you entered was wrong.
HDB does not issue a receipt. Instead, an acknowledgement page appears after payment with your order reference number on it. Save or screenshot it: every follow-up depends on that number.
Step 5: receive the plan
If the plan is available, you can download it immediately after payment. If not, HDB processes it and emails it to you within 3 working days. Check the address you entered, and check your spam folder before assuming nothing came.
The plan is an A4 sheet at 1:100. To print it to scale, set Page Sizing to "Actual Size" in the print settings; any fit-to-page option will quietly shrink it, and every ruler measurement with it. HDB keeps the copyright, and the plan may not be reproduced or published without HDB's written consent.
If the plan does not arrive, or does not exist
If nothing has arrived after 3 working days, email HDB at hdb_sop@hdb.gov.sg with your order reference number. The terms and conditions page also gives an enquiry line, 6490 3203.
Some units have no plan to sell. HDB's terms say a plan is not available for a unit at the construction stage, or for one undergoing an improvement or conversion scheme. Beyond those cases, we could not confirm whether plans exist for every flat, including the oldest SIT-era and early HDB blocks, so a nil result is not necessarily an error in your application.
A different problem, and a much more common one: the plan arrives, and it is not the flat you live in. That is almost always previous owners' renovation work, which never reaches the archived drawing. HDB's terms say so directly: renovation by the flat owner, and any recess area the owner bought, are not shown on the plan, which HDB provides "as is" and "to be used only as a guide". The archive is a record of the original build, not a live record of the unit. What to do about that gap is set out in what to do when the floor plan is missing or wrong.
If you are renovating: what your contractor needs from you
HDB states it plainly on its renovation permit page: "Renovation contractors are to submit to HDB, the flat's floor plan showing the proposed work, together with the electronic application for renovations."
So the division of labour is fixed. Your contractor submits the permit application electronically. You supply the plan they mark up. Works such as the demolition of walls are evaluated by HDB, which refers to ensuring that your flat's structural integrity is not compromised, so the plan is also how your contractor identifies which walls they may propose to touch at all. Get the plan before the quotation, not after. The permit itself, what needs one and who applies, is covered in HDB renovation permit.
If it is not an HDB flat, you are in the wrong queue
HDB holds HDB flats. For a private condominium or landed house, the approved building and structural plans come from BCA's Plan Purchase System, which charges S$45 per address to search and then S$65 per plan reference number, both inclusive of GST. The planning records, meaning the Written Permission and the plans approved under it, come from URA's Buy Planning Records (DC 15) e-service, whose search fee is S$109 inclusive of 9% GST. The full BCA procedure is in BCA plan purchase, and condo floor plans in Singapore matches each route to the document it actually returns.
When buying the plan is not the answer at all
Buy the plan from HDB first. It is the cheapest possible answer and for most flats it is the correct one. The exceptions are narrow and specific: fitted carpentry where a centimetre of error is expensive, a dispute about what a previous owner altered, a need for verified dimensions rather than a schematic layout, maisonettes and jumbo or converted flats where the record may not reflect the unit, and commercial or institutional HDB property undergoing A&A works where a Qualified Person needs existing-condition drawings.
In those cases the deliverable is a measured record of the unit as it stands today: 3D laser scanning to capture it and as-built documentation to draw it up. That is a drawing service. It does not replace a Qualified Person's submission to the authority, a Professional Engineer's structural assessment, or a Registered Surveyor's endorsement of boundaries or strata area, and no scan changes who is entitled to sign what. Send us the flat type and what the drawing is for and we will tell you straight whether it is warranted.
