DC - Business 2 (Industrial)

Introduction

Industrial developments comprise factories, warehouses, telecommunication and utility buildings. These developments may be allowed on land zoned Business 1 (B1) or Business 2 (B2).

Depending on the nature of their activities, clean and light industries are allowed in Business 1 (B1) zone. General and special industries are to be located in Business 2 (B2) zone.

The National Environment Agency (NEA) would require a 100m nuisance buffer from a B2 zone to the surrounding area. The different types of industries and their associated buffer requirements can be found in NEA's Code of Practice for Pollution Control (SS593). QPs / developers / owners may also submit an Industrial Siting Consultation (ISC) to NEA to seek advice on the proposed use of their industrial premises  - more information can be found on NEA's website.

Gross Plot Ratio

The Gross Plot Ratio (GPR) of a B2 development is guided by the GPR specified in the Master Plan (MP). This upper bound GPR may not always be achievable because of site limitations like plot size, shape of the plot, site topography or ground conditions, building setbacks, building height or technical requirements of other authorities that may affect the site.

The area of the land required to be set aside for Drainage Reserve1 (DR) and/or Road Reserve2 (RR) to be vested in the State may be included in the site area to compute the gross floor area (GFA) for a GPR – see figure below.

1 Drainage Reserve: An area safeguarded for purposes of building or widening a public drain.

2 Road Reserve: The plot of land to be vested in the State as required under the Street Works Act. It is demarcated by the line of Road Reserve in the Road Line Plan and the site boundary.

GPR for sites where vesting is required
GPR for sites where vesting is required

B2-White

B2 sites located next to MRT stations may be zoned B2-W. The white component is to provide flexibility for industrial companies in such locations to accommodate synergistic White uses.

For such B2-W sites, a minimum GPR shall be achieved for the permissible B2 uses first. This minimum GPR for B2 uses is indicated in the square brackets on the Master Plan.

For example, in the map below, the site next to Joo Koon MRT Station is zoned “2.5 [B-2.0] W”. A B2-W site would have an overall allowable GPR of 2.5. A minimum GPR of 2.0 must be achieved and used for industrial purposes before the remaining GPR 0.5 may be unlocked for White uses.

Refer to the section on Allowable Uses for the list of allowable uses within the White component.

Bonus GFA Incentive Schemes

The Bonus GFA schemes applicable to Business 2 are:

Built Environment Transformation Scheme

The Built Environment (BE) Transformation GFA scheme aims to encourage adoption of higher tier Construction Industry Transformation Map (ITM) outcomes in areas of digitisation, productivity and sustainability. The incentive scheme is jointly administered by BCA and URA. Applicants may qualify for the scheme by adopting stipulated ITM outcomes as part of the development proposal. 

Eligibility

The incentive is applicable for new erection or major Addition & Alterations to private sites of at least 5000sqm GFA1. Sites launched under the Government Land Sales (GLS) programme prior to 31 March 2022 may also be eligible for the incentive scheme.

The types of developments eligible for the incentive scheme are as follows:

Residential2

Condominium and Flats development  

Non- Residential

Commercial, Industrial and Institutional developments, such as office, retail, business parks, community building, hotel, hospital or white site developments 

Mixed use

Combination of the above 

1Smaller developments of less than 5,000 sqm GFA may be considered on a case-by-case basis if agencies determine that sizeable productivity and sustainability outcomes relative to the development proposal can be achieved based on BE ITM measures proposed by the developers.

2The maximum allowable number of dwelling units for residential developments located outside of Central Area is derived from the Master Plan permissible intensity, which excludes any bonus GFA the site is eligible for.

Quantum of bonus GFA allowed

Private sites may be granted up to 3% bonus GFA under the scheme3. The scheme is applicable for new proposals till 23 November 2026.

GLS sites are eligible up to 2% bonus GFA. The scheme is applicable for new GLS launched prior to 31 March 2022.

The cumulative bonus GFA shall be kept within the overall budget of 10% above the Master Plan Gross Plot Ratio (GPR), or the maximum allowable GFA of the development. It shall not form the future development potential of the site upon redevelopment. 

The quantum of allowable bonus GFA under the BE Transformation Scheme is based on the proposed uses, use quantum that complies with the Master Plan zoning, and any additional requirements imposed as part of the endorsement for the bonus GFA. 

Should development proposals fall within areas with specific planning considerations (e.g. storey height controls) or are unable to fully accommodate the additional intensity due to on-site conditions (e.g. areas with traffic concerns), the bonus GFA under the BE Transformation Scheme that can be approved may be lower than the endorsed quantum, and/or the bonus GFA may be limited to a particular use or uses.

3Applications submitted under the Strategic Development Incentive (SDI) and Central Business District (CBD) incentive schemes will have to comply with stipulated outcomes in the areas of digitalisation, productivity and sustainability. The required ITM outcomes will be separately assessed in relation to the context of the proposal, upon submission of the outline application for the SDI/CBDI development proposal. ITM outcomes will be imposed as conditions for planning approval for redevelopment proposals via the SDI/CBD Incentive scheme. SDI/CBDI proposals will not qualify for the additional GFA under the BE Transformation Gross Floor Area Incentive Scheme.

Submission

Applicants are to submit an application to BCA with supporting documents on the proposed ITM outcome concept plan and detail the proposed ITM outcome to be adopted for the development proposal. The submission can be made at this link

Following BCA’s grant of letter of acceptance, applicants shall submit the development proposal with the proposed quantum and use group of the proposed bonus BE Transformation GFA to URA, for detailed assessment. The development application shall be submitted within 6 months from BCA’s grant of Letter of Acceptance, and shall include a copy of the Letter of Acceptance, and the BE Transformation GFA computation form. The submission process and verification of ITM outcomes is summarised at this link.

Requirements on ITM Outcomes for Bonus BE Transformation GFA

Applicants are to comply with BE ITM outcomes for the bonus scheme based on the building type. The specific requirements for the development proposal will be shared in detail as part of the application process to BCA for the Letter of Acceptance.

ORA within Privately-Owned Public Spaces (POPS)

Refer to section on POPS.

District Cooling System (DCS) or Centralised Cooling System (CCS) scheme

The scheme aims to encourage building owners to adopt either DCS or CCS for their building. This could be by collaborating with other building owners to establish new DCS or CCS networks, or tapping onto an existing DCS or CCS network in the area.

Host Developments

Host buildings in DCS and CCS networks will need to set aside spaces for the district cooling plant and chiller plants respectively to serve the larger network. Such Mechanical and Electrical (M&E) spaces needed to support the DCS/CCS network will be allowed as bonus Utility GFA, over and above the Master Plan allowable GFA for the site. The additional Utility GFA may be subject to payment of Land Betterment Charge (LBC), if any.  

For CCS networks:

  • If the host building’s original in-building chiller plant (IBCP) spaces are computed as GFA, these can then be computed as bonus Utility GFA. The freed up GFA from the original IBCP can be put to other uses in the development. 

  • If the host building’s original IBCP spaces are exempted from GFA1, bonus GFA equivalent to the size of the IBCP room will be allowed over and above the Master Plan allowable GFA for the site. Bonus GFA may be subject to payment of LBC based on its proposed use.

The DCS/CCS-related M&E spaces may also be considered for GFA exemption if the spaces fulfil the respective criteria of the prevailing M&E-related GFA exemption schemes

1Applies to IBCP spaces within the building envelope that were previously granted GFA exemption based on the relevant GFA exemption provisions. Does not apply to open-to-sky IBCP spaces (e.g. on the rooftop)

Submission requirements

The following information / documents are to be furnished to URA as part of the development application (DA):

To indicate clearly on the submission plans how the bonus GFA / freed up GFA from the existing IBCP spaces will be put to use.

Receiving Developments

Developments receiving chilled water from the host building(s) in a DCS/CCS network benefit from not having to provide their own in-building chiller plant (IBCP) systems. The following GFA incentives are applicable for such receiving developments:

Scenario

GFA incentives

Decommissioning of the IBCP space in an existing building, as part of Addition & Alteration (A&A) works

Where the existing IBCP space is computed as GFA

  • The building owner can choose to convert the IBCP space in-situ to another use or decant the GFA from the decommissioned IBCP space to another part of the building1.

  • Proposed use of the converted or decanted GFA may be subject to payment of LBC, if any.

Where the existing IBCP space is exempted from GFA2

  • Bonus GFA equivalent to the size of the decommissioned IBCP space will be allowed over and above the Master Plan allowable GFA for the site1

  • Bonus GFA may be subject to payment of LBC based on its proposed use

1Owners should first consider converting the decommissioned IBCP space to other uses in situ, as opposed to demolishing the floor slab of the IBCP space to decant the GFA / deploy bonus GFA elsewhere within the development. Proposals to demolish the floor slab will be subject to evaluation, with justifications to be provided (e.g. whether there are constraints faced in retrofitting the original IBCP space for other uses)

2Applies to IBCP spaces within the building envelope that were previously granted GFA exemption based on the relevant GFA exemption provisions. Does not apply to open-to-sky IBCP spaces (e.g. on the rooftop)

Building requires the provision of M&E spaces to support the connection to the DCS/CCS network (e.g. heat exchanger room)

  • Such DCS/CCS-related M&E spaces will be allowed as bonus Utility GFA, over and above the Master Plan allowable GFA for the site. The additional Utility GFA may be subject to payment of LBC, if any.

  • These M&E spaces may also qualify for GFA exemption if the spaces fulfil the respective criteria of the prevailing M&E-related GFA exemption schemes

Submission requirements 

The following information / documents are to be furnished to URA as part of the development application (DA):

 

DCS/CCS Receiving Development

Network plan

Plan showing the existing DCS/CCS network that the development is intending to connect to

Service provider

Supporting documents showing that a DCS/CCS service provider for network has been identified, with the new network or connection found to be feasible (e.g. feasibility study by service provider, service agreement)

Provision of cooling-related M&E spaces

The necessary DCS/CCS cooling-related M&E spaces to be clearly reflected on the submission plans (e.g. heat exchanger room)

Proposed use of decommissioned IBCP spaces (as part of A&A works)

All existing IBCP spaces are to be decommissioned. To clearly show the location of all the existing IBCP spaces on the submission plans, and the proposed use of the decommissioned IBCP spaces.

If GFA from the decommissioned IBCP space is proposed to be decanted to other parts of the development, to provide justifications why the original IBCP space could not be converted for other uses in situ

Eligibility

The following types of developments will not be eligible for the GFA incentives:

  • Existing buildings that are already connected and part of a DCS/CCS network, as the GFA incentives will not retroactively apply to such buildings.

  • Where it is a mandatory requirement for the development to adopt DCS/CCS (e.g. as part of conditions of tender in Government Land Sales sites). 

Specific to receiving developments who wish to tap onto an existing DCS/CCS network, the following criteria are to be met before the GFA incentives will apply:

  • The receiving development was originally approved at a time when there was no operational DCS/CCS network in the area; or

  • The receiving development shall be a minimum age of 10 years1 (from date of original TOP).

Where necessary, the bonus GFA may be approved on temporary basis for monitoring purposes of this new scheme.

1 This is the average lifespan of an IBCP system. The intent is to discourage the premature decommissioning of IBCP systems of newly completed buildings. Owners of newer buildings can instead consider switching to DCS as part of their planned IBCP replacement cycles (i.e. after 10 years).

The Bonus GFA is allowed over and above the MP GPR subject to a maximum of 10% of the MP GPR. When the site is redeveloped in future, the additional GFA already used under the bonus GFA incentive schemes shall not be carried over. In other words, the GPR for the site shall revert to the GPR specified in the prevailing MP.

Although a site may make use of multiple bonus GFA incentive schemes, the total bonus GFA shall not exceed the overall cap of 10% above the MP GPR.

Building Setback from Boundary

Setback Requirements
Setback Requirements

All industrial developments shall be sufficiently set back from the road and common boundary. The setback distance is measured from the road reserve1 line or boundary line to the external wall of the building, excluding land to be vested to the State for road and/or drainage purpose.

All industrial developments fronting a public road shall provide a road buffer, the width of which depends on the hierarchy of the road. A green buffer shall be set aside in the road buffer depending on the width of the road buffer.

The buffer requirements for the Road Categories 1 to 5 are in Table 1 below. The common boundary setback requirements are in Table 2 below.

Parking

LTA prescribes the parking provision standards and requirements for motor vehicles and bicycles. The requirements are usually based on the quantum of the gross floor area or the number of units of the development uses.

Separately, to enhance commuter experience and reduce congestion at Pick-up and Drop-off Points (PUDOs), LTA and URA collaborated with the industry to develop a design guide for PUDOs containing best practices that building owners and professionals can consider applying to new and existing PUDOs.

Car and Motor-Cycle Parking

Under LTA’s Range-based Parking Provision Standards (RPPS), developments are subject to car and motor-cycle1 parking provision requirements.

Unless explicitly approved as private parking lots in the approved plans, all car and motor-cycle parking lots shall be treated as common property.

1 Motor-cycle parking provision is mandatory in all non-residential developments.

Range-based Parking Provision Standards (RPPS)

The RPPS allows developments to provide any level of car and motor-cycle parking provision within a specified range, defined by a lower bound and an upper bound – see figure below. The range varies according to location zones and land uses. Details may be found in LTA’s Code of Practice for Vehicle Parking Provision in Developments.

Range-based Parking Provision Standards
Range-based Parking Provision Standards

New B2 developments shall be subject to a process of waiver evaluation by LTA, if one wishes to provide surplus car and motor-cycle parking lots, ie parking provision above the upper bound based on the new RPPS.

Private Parking Lots

Within multi-user developments, industrial strata units may be allowed to have their own private car/lorry parking lots subject to the following:

  • The private parking lots are surplus parking lots over and above LTA’s minimum parking provision;

  • The floor area of the private parking lots shall be computed as GFA under the 40% ancillary quantum of each strata-unit;

  • The private parking lots are physically contiguous to the industrial strata unit.

For approved private car/lorry parking areas that were previously not computed as GFA, they may be converted to other allowable useable area subject to the following:

  • These areas are computed as GFA and the resultant GFA does not exceed the current MP GPR Control for the development site;

  • The proposed conversion is authorised by the MCST via a 90% resolution;

  • The remaining number of parking lots after conversion still meet LTA’s minimum parking provision;

  • SLA may levy Land Betterment Charge, where applicable.

Bicycle Parking

To promote a car-lite society, B2 developments may be required to provide bicycle parking facilities within the developments. Refer to LTA’s Code of Practice for Vehicle Parking Provision in Developments here for the list of requirements.

Unless explicitly approved as private parking lots in the approved plans, all bicycle parking lots shall be treated as common property.

Bicycle parking lots provided according to LTA’s new standards are exempted from GFA computation. Surplus provision of bicycle parking lots may be exempted from GFA computation depending on merits and context of the development.

Minimum Unit Size

Minimum Unit Size
Minimum Unit Size

The minimum size of an industrial unit is 150sqm. This is deemed a meaningful space to meet the operational needs of industrial uses.

Use Quantum

At least 60% of the total B2 industrial GFA (ie minimum 60%) shall be used for industrial purpose1. The remaining 40% may be used for ancillary (or supporting) uses. Tables 1 and 2 below shows the applicable use quantum control for a single-user or multi-user industrial development respectively.

Guidelines for Allowable Uses

Guidelines on Showroom

Showroom in industrial premises are meant primarily for the display of two categories of products as follows:

  • Products that are not typically transacted or exchanged over the counter (eg bulky items such as furniture, motor vehicle).

  • Products that are predominantly delivered and installed off-site (eg floor tiles)

Incidental sales of small items or “cash-and-carry” products may be considered only if the main activity of the showroom is for display of the two categories of products listed above.

Showroom proposals will only be considered as part of a Change of Use application, after the building has obtained a Temporary Occupation Permit (TOP) and when the prospective end-user or business operator for the showroom space is known.

Showroom may be considered subject to the following:

  • Showroom shall be confined to the 1st storey of the development.

  • SLA may assess such showrooms based on Group A Commercial rate for the purpose of computing Land Betterment Charge.

Guidelines on Ancillary Display Area

An ancillary display area is meant only for the display of products related to the predominant industrial operations in the development.

Ancillary display area may be considered subject to the following conditions:

  • Displayed products are purely for corporate or demonstration purposes that serve corporate customers of the industrial companies only and not open to public;

  • These products cannot be sold on-the-premises or on site;

  • There shall be no strata-subdivision or sub-leasing of these areas; and

  • Endorsement from relevant agencies (eg HDB & JTC for leased premises; EDB & ESG for private premises) may be required.

SLA may assess such ancillary display areas based on Group D Industrial rate for the purpose of computing Land Betterment Charge.

Conversion of Previously-Approved Ancillary Showroom

If an existing industrial development has a previously approved ancillary showroom (now re-termed Display Area), the owner or operator of such ancillary showroom may apply for planning permission to convert it to a showroom in accordance with the showroom definition and guideline stated above.

Alternatively, the previously approved ancillary showroom may be expanded to function as an enlarged ancillary display area in accordance with the current definition for ancillary display area and guideline stated above.

Guidelines on Temporary Workers’ Dormitory

Workers' dormitory are premises used to house migrant workers who are engaged to carry out industrial or production or construction activities. Dormitories may comprise new extensions to existing buildings or new building blocks within an industrial development or may be converted from existing spaces within an industrial development.

New workers’ dormitories located outside specified areas (refer to Table 1 and 2 below) or renewal of existing dormitories may be considered on Temporary Permission (TP) for up to 5 years subject to compliance with prevailing guidelines and the use not causing disamenities.

To provide more temporary housing options for migrant workers while additional purpose-built dormitories are being constructed, URA and technical agencies will now assess applications for (i) new temporary workers’ dormitories and (ii) increase in the number of workers in existing dormitories located within the specified industrial areas (refer to Table 1 below) on individual basis. If supported, the use will be on 3-years TP, and may not be renewed subsequently.

Note: The following guidelines are for workers’ dormitories located within industrial developments. Independent workers’ dormitories located separately from the industrial development may be allowed only on land zoned Civic and Community Institution. Click here for Guidelines for independent workers’ dormitories.

Types of Temporary Workers’ Dormitories

  • Ancillary dormitories may house only workers employed by the owner or lessee of the industrial development and workers who work on-site in the subject development.

  • Secondary dormitories may house workers not employed by the owner or lessee of the industrial development as well as workers who work on- and off-site.

Location

  • All new proposed workers’ dormitories or increase in capacity within industrial developments are assessed on the merits of the case.

  • New applications located within 13 specified industrial areas (refer to Table 1) will only be considered if the proposals meet prevailing guidelines, and can be supported by existing infrastructure as assessed by technical agencies. Please refer to the circular dated 10 Feb 2023 for more information.

  • Prior clearances from NEA, PUB, SCDF, and LTA shall be obtained before a proposal is submitted to URA for evaluation.

Earthworks, Retaining Walls, and Boundary Walls

Earthworks

Earthworks are defined as any operations or works in, on, or over land which result in substantial modification to the existing ground terrain, land form, or slope. These include excavation, formation of a new slope or embankment, and cut and fill operations.

Extensive earthworks are discouraged as it may change the existing terrain. Earthworks may also result in the building of high retaining walls that mar the streetscape and have adverse impacts on the surrounding areas. Earthworks on any development site, where necessary, shall be minimised.

Planning permission is required if earthworks involve more than 2,000sqm of land or change in the level of the land of more than 1.5m anywhere in the development site or relative to the neighbouring land.

The guidelines for earthworks are dependent on where the earthworks are carried out.

Location of Allowable Earthworks
Location of Allowable Earthworks

Earthworks within the building setback area

Earthworks may not be allowed within the building setback area, except in the following circumstances:

  • When the proposed earthworks are to match the existing platform levels of the neighbouring sites;

  • When the sites are on undulating or sloping terrain, with large differences in platform levels within the site, or between the site and the road;

  • When the earthcut is necessary to build a fully submerged basement. The area within the building setback shall be reinstated to the original platform level upon the completion of the basement.

Earthworks within the build-able area (ie outside the building setback area)

Earthworks within the build-able area of more than 1m are subject to evaluation depending on merits. If the earthfill of more than 1m is allowed, the earthfilled area shall not be counted as an additional storey provided the overall aggregate building height complies with the maximum allowable building height measured from the allowable platform level.

Earthworks within the entire development site

Earthfill involving the entire development site may only be considered if the proposed earthworks are required to meet the technical requirements of PUB. Such earthfill may be allowed up to the Minimum Platform Level (MPL)1 stipulated by PUB.

1 Minimum Platform Level (MPL): The minimum 1st storey level to be provided within the site. The MPL is determined by the Public Utilities Board (PUB).

Retaining & Boundary Walls

Allowable Height of Retaining and Boundary Walls
Allowable Height of Retaining and Boundary Walls

The maximum allowable height for boundary walls is 1.8m.

High retaining walls shall be avoided wherever possible, particularly for small in-fill plots. If they have to be built and can be allowed, they shall meet the following requirements:

  • the height shall be less than 1.5m;

  • retaining walls higher than 1.5m may be considered due to site constraints and the need for extensive excavation;

  • the total visible height of the solid boundary-cum-retaining wall shall not exceed 2.8m, of which the solid boundary wall shall not exceed 1.8m.

If the retaining walls are to meet the MPL requirement stipulated by PUB for drainage purposes, the retaining walls along the site boundaries (except along boundaries that abut foreshore, roads, or waterbodies with drainage reserve equal to or more than 17.5m wide) need not be tiered as these are transitory, pending the redevelopment of the neighbouring land to the same MPL.

The above are general guidelines for earthworks and retaining walls. For industrial developments, these guidelines will apply differently depending on the type of development on the neighbouring parcels of land.

Earthworks for industrial scenarios where the guidelines apply (see full illustration here)
Earthworks for industrial scenarios where the guidelines apply (see full illustration here)
Earthworks for industrial scenarios where the guidelines do not apply (see full illustration here)
Earthworks for industrial scenarios where the guidelines do not apply (see full illustration here)
  1. Where the boundary is shared with an industrial development (B1/B2) or a business park:

    • The existing earthworks guidelines and controls on retaining and boundary walls shall not apply.

  2. Where the boundary is not shared with an industrial development (B1/B2) or a business park:

    • The existing earthworks guidelines and controls on retaining and boundary walls shall apply.

  3. Where the boundary abuts a public road:

    • The existing controls on earthworks, retaining, and boundary walls shall apply.

    • Earthworks guidelines shall not apply if the development beyond the public road is an industrial development (B1/B2) or a business park.

  4. Where the boundary abuts a drainage reserve4:

    • The existing controls on retaining and boundary walls shall not apply.

    • Earthworks guidelines shall not apply only if the development beyond the drainage reserve is an industrial development (B1/B2) or a business park. If the development beyond the drainage reserve is not an industrial development or business park, the earthworks guidelines shall apply.
