Buy it from HDB's Purchase of Residential Floor Plan e-Service at services2.hdb.gov.sg. The service is reported to take a Singpass login, a card payment of S$5 per plan, and to email the plan to you as a PDF. 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.
One caveat that shapes everything below. HDB's public pages render their content with JavaScript and the e-Service sits behind a Singpass login, so on 14 August 2026 no automated fetch could read the fee, the payment methods or the delivery timing off an HDB page. Every figure here is attributed for that reason. The e-Service itself is the authority on all of them, and it will show you the current fee before you commit to paying.
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 key collection documents. A hardcopy is reported to be handed over at key collection. If you are the original owner, it may be in the folder you have not opened since.
- The HDB flat portal. It is widely reported that buyers can download their unit's floor plan at no charge through the portal during the purchase stage. We could not confirm that on an HDB page, so treat it as worth checking rather than as a guarantee: log in 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
The e-Service is reported to ask for a Singpass login, the flat address, a valid email address, a local contact number, and a credit card, Visa or Mastercard. Have the exact block, street and unit number in front of you rather than working from memory.
Eligibility is the one item we cannot resolve for you. We could not establish whether the e-Service is open to any user or restricted to the registered owner or occupier of the flat, and we are not going to repeat a third-party claim in either direction. The service will tell you at login.
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 supporting pages are its get help page and its terms and conditions page. Log in with Singpass when prompted.
Step 3: select the flat and the plans
Enter the address and select the plan or plans you want. The e-Service is reported to cap each application at 5 plans; if you need more, submit a second application. 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 listed as S$5 per unit floor plan, inclusive of GST, payable by credit card, Visa or Mastercard. Read the figure on the screen in front of you rather than trusting this page or any other: published third-party figures for government e-services go stale quietly, and no page outside HDB can tell you today's fee with authority. We could not establish whether any refund is available if the plan turns out not to exist, so treat the payment as spent once made.
Step 5: receive the plan
Delivery is listed as a softcopy PDF by email. If the plan is already available it is reported to be downloadable immediately after payment; otherwise it is reported to be processed and emailed within about 3 working days. Check the address you entered, and check your spam folder before assuming nothing came.
If the plan does not arrive, or does not exist
Start with HDB itself: the get help and terms and conditions pages linked above are the right first stop, and the e-Service records your application. 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. 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.
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.
