GUIDE TO SET UP AN URBAN FARM ON HDB MULTI-STOREY CARPARK ROOFDECK
Highlights
SFA aims for Singapore to produce 30% of its nutritional needs by 2030. Rooftop farms are one of the
solutions and SFA has worked with HDB to secure under-utilised HDB multi-storey car park (“MSCP”)
rooftop parking decks (the “Premise”) to be converted to increase the supply of space to meet farming
needs. SFA will be progressively appointing farm operators for the various sites.
If you are thinking of setting up an Urban Farm at a HDB MSCP rooftop parking deck, this guide will let
you have a better understanding of the procedures to follow, including information on the various
submissions, fees and timelines involved. This guide also introduces the government agencies
overseeing the necessary permits, should you wish to contact them to make specific enquiries.
The following agencies have contributed to this guide: Singapore Food Agency, Housing Development
Board, Building & Construction Authority, National Environment Agency, Public Utilities Board, Urban
Redevelopment Authority and Singapore Civil Defence Force.

a separate application to PUB. Further information can be found online, at:
https://www.pub.gov.sg/savewater/atwork/alternatesources
- The collected rainwater is only allowed for non-potable use within the Successful Tenderer’s

to other parties for use at other premises is not allowed.
7. After all relevant agencies’ approval are obtained, construction and related works can commence.
Please adhere to these guidelines for any proposed works at the MSCP Premise.
a) The proposed works and all daily operations, equipment and fittings shall not affect
the safety aspects of the building, including structural safety, fire safety, operational
safety, etc. Where measures need to be taken arising from the works and operations,
this is to be done at the Successful Tenderer’s own cost
6b) The proposed works shall not affect the vehicular access/ driveways/ parking lots and
operational requirements to serve the existing HDB precincts. The consultant/
contractor is also required to ensure motorists and pedestrians safety.
c) Ensure that the proposed works will not cause ground settlement and all protective
measures are to be implemented to ensure the vehicular road access/driveway is not
adversely affected by the proposed works. No dumping or stockpiling of building
materials, equipment etc. are allowed in HDB car parks and access.
d) At all times, the function of the driveways should not be compromised e.g. for refuse
collection, fire-fighting etc. Motorists need to be able to gain access to HDB car parks
at all times.
e) Necessary measures must be put in place to ensure public safety at all times and
warning signage must be erected adequately. HDB Branch must be kept informed of
the work schedule and details once available especially when it is approaching HDB’s
car parks / access roads.
f) For car parks that have been implemented with the Electronic Parking System (EPS),
should any of the EPS equipment be affected by the proposed works, the consultant/
contractor is to bear all costs relating to the relocation/ replacement of the equipment
(e.g. relocation/diversion of EPS, loss of parking revenue, replacement of EPS parts,
etc.). The consultant/contractor is also required to make arrangement with HDB’s
appointed EPS service provider on the relocation/ replacement works. Should the EPS
contract be terminated prior to the contract end date due to the proposed works,
HDB will seek compensation for the losses and expenses due to the early termination
of the contract period.

Helpful Tips
1. For works requiring a QP, consider engaging someone who is familiar with and understands
farm operations/ needs
2. Appoint a competent licenced builder to ensure that building works are built in accordance to
approved plans and are code compliant. This will minimise issues during post-construction
inspections.
Submissions to NEA
3. To facilitate NEA submission, you are advised to provide the following information:
a. Tabulation of refuse output and clarify how each generated waste stream will be
stored, transported and disposed;
b. Farming process activities, proposed working hours, type of chemicals/fertilisers
used;
c. Clarify mitigation measures to ensure that the proposed use will not cause odour,
noise or pollution issues to the premises and its vicinity; and
d. Ensure no roof gutters are installed and avoid features that may result in water
stagnation and become potential breeding habitat for mosquitoes.
9e. To declare upfront any requirements that are not able to comply with the Code of
Practice on Environmental Health (COPEH) and the Code of Practice for Pollution
Control SS593:2013.
4. If you have a specific question related to your submitted farm plans, please contact the
NEA processing officer assigned to your project. Otherwise, please submit a Building Plan
Consultation Request at
https://www.eportal.nea.gov.sg/app/#/applications/create/building-plan-
consultation-request or drop an email to DCLD_Consultation@nea.gov.sg for all other
enquiries.
Submissions to URA
5. Waiver application process for URA’s Addition and Alteration submissions via CoreNet:
a. QP submits a waiver on the CORENET platform, indicating the specific URA condition
/ guideline to be waived
b. The QP will have to provide the reasons for the deviation, consider the potential
impact on the amenity of surrounding developments and streetscape, and propose
appropriate mitigating measures.
c. The request will be considered on a case-by-case basis and a reply will typically be
provided within fifteen (15) working days.
Submissions to PUB
6. Check if your development plans are eligible for PUB’s Simplified Submission Scheme. This will
reduce the processing time.
7. Check your BIM model using PUB’s e-Plan Checker for compliance with PUB's requirements
before making your submission to CORENET. This reduces your clearance time provided the
modelling submitted has been reviewed and cleared of all non-compliances. For more info on
PUB's BIM e-Checker, please refer to the following link at
https://buildingplanchecker.pub.gov.sg.
8. If you have questions about your submission, you can book a consultation or find out the
status of submission through our QP Portal E-services at
https://www.pub.gov.sg/compliance/qualifiedpersonsportal/eservices. For further
assistance, please call PUB Building Plan Division (BPD) hotline at 67313512 during office
hours between 9am to 5pm, or email to pub_bpu@pub.gov.sg.
Submissions to BCA
9. Structural design standards to be used are indicated in the BCA’s Approved Document, which can be
consulted here:
https://www.bca.gov.sg/Publications/BuildingControlAct/others/Approveddocument.pdf
10. The safety of occupants is paramount. For safety reasons, requests for partial TOP (i.e. splitting of the
development plot to allow for TOP to be received earlier for part of the site) will not be accepted if
there are on-going structural works and/or crane hoisting works within the land site.
1011. The Code on Envelope Thermal Transfer Value (ETTV) calls for sufficient thickness of glass to prevent
energy loss if a greenhouse is air-conditioned. Alternatively, a developer can provide energy saving
mitigation measures such as solar panels to make up for energy loss from the use of thinner glass.
12. Please refer to SS 555: 2019 for design and technical compliance to Lightning Protection System.
Maintenance Matters
The following maintenance matters are also highlighted for attention:-
a) The Successful Tenderer will be responsible for taking over the property in as-is condition, and
maintenance of the space within the tenanted boundary. Generally, the tenanted boundary
is pegged to the bottom of the vehicular ramp serving the parking deck, but it will exclude
shared building systems.
b) The Successful Tenderer shall apply for and bear all costs for installation of water and electrical
sub-meters. The tenant must also open its own utilities account and cover all related charges
incurred for supply of water, sanitation, refuse removal, electricity usage etc. The utilities
account will need to commence together with the tenancy commencement date, even if there
is any concessionary rent-free period granted.
c) The Successful Tenderer will be held responsible for the maintenance of the site, e.g. cleaning,
pest control, proper refuse removal from site to the bin centre, and fulfil all other
maintenance responsibilities as stated in the Tenancy Agreement.
