Statistical Gross Floor Area (SGFA) and Plan Fees
Learn how to compute Statistical Gross Floor Area (SGFA) and define General Building and Specified Building for the purpose of application of plan fees rates.

How Plan Fees are charged
Plan fees are computed based on the type and extent of building works as stipulated in the Second Schedule of the Building Control Regulations. This approach ensures that fees are proportionate to the regulatory effort.
Rates of fees are also different for Type 1 and non-Type 1 buildings. Type 1 building means any agricultural or industrial building, being a building that is constructed or used, or is to be constructed or used, primarily for one or more of the purposes as outlined in Second Schedule of the Building Control Regulations.
What is SGFA
Statistical Gross Floor Area (SGFA) is used to proxy the extent of the building works.
The type of building works may be further broken down into general buildings and specified buildings.
SGFA of general buildings consist of all floor areas in a development. This includes:
All floor areas within the building, such as:
Floor areas, including ledges
Catwalks
Lift motor room
Roof terraces/ Sky terraces/ Maintenance roofs etc., regardless of usage
Constructed areas within the development, such as:
Landscape deck
E-deck
Elevated floor areas
Covered areas, such as:
Car porches & garages in landed housing
Communal landscaped areas
Entrance canopies and covered main entrances
Public spaces and concourse areas
Drop-off points
Walkways and footways
Linkways and sky bridges
Urban verandahs
Car parks including driveway & ramp up
Loading and unloading bays
Area of plan view of specified buildings, on the other hand mean the areas of the following non-exhaustive list of structures:
A bridge
A bund
A canal
A chimney
A dry dock
A jetty
A landing stage
A lighting mast
A pier
A retaining wall
A tank (other than a water tank on a roof)
A tunnel
An underpass
A wharf
A sewage treatment plant
A silo
A slip dock
A slope
A swimming pool
Any other similar structure
A building’s SGFA can also be categorised into:
Above sublevel:
for storey that has a finished floor level not more than 6 metres below the finished floor level of the first storey.
for the first storey of the building.
for any storey above the first storey.
Below sublevel:
for storey that has a finished floor level is more than 6 metres below the finished floor level of the first storey.
For projects in which the first set of plans is submitted to the Commissioner of Building Control (CBC) for approval on or after 1 October 2025, the fee structure have been streamlined such that SGFA within the development are to be aggregated regardless of building type (general or specified building). Please see circular [PDF, 400 KB] for more details below for the Plan Fee Structure for the new rate to be applied.
Please refer to the Second Schedule of the Building Control Regulations for further details.
Other components in the computation of Plan Fees
For Addition & Alteration (A&A) and reconstruction works, as well as departures and deviations from approved plans, there are also flat fees charged per storey on top of the new SGFA of the development. Please see below for the Plan Fee Structure for more details.
From 21 May 2025, BCA has also streamlined the fees payable for facade A&A works. Instead of a flat fee per storey, fees are computed at a rate of $500 per typical design per building, regardless of the building typology and number of storeys of the building where the proposed façade A&A works will be performed. Please see this circular [PDF, 193 KB] for more details.
Plan Fee Structure
Details of the revised fees structure applicable for all projects whose first set of plans is submitted to BCA for approval on or after 30 December 2024 are tabulated below:
Plan fees for various types of building works, including new SGFA, A/A works, amendments, and demolition, with rates based on area, storeys, or height.
S/N | Type of Building Works | SGFA/Area of Plan View/No. of storeys | Rate |
|---|---|---|---|
1 | New SGFA for General Building and/or New Area of Plan View for Specified Building | A1 below sublevel | $400/100m2 |
B1 above sublevel | For 1st 2,500 m2 of SGFA $300/100m2 | ||
Subsequent SGFA $270/100m2 | |||
2 | New SGFA for Type 1 Building and its New Area of Plan View for Specified Building Note: Plan Fee for Mixed Development where the Specified Building does not form part of the Type 1 Building shall be computed under item 1 | A3 below sublevel | $400/100m2 |
B3 above sublevel | For 1st 10,000 m2 of SGFA $150/100m2 | ||
Subsequent SGFA $220/100m2 | |||
3 | A/A works without structural (ST) plan Submission [Any increase in area to be computed under item (1) or (2)] | No. of Storey | $200/storey |
4 | A/A works for Residential Bldg with structural (ST) plan Submission [Any increase in area to be computed under item (1) or (2)] | No. of Storey | $200/storey |
5 | A/A works for Non- Residential Bldg with structural (ST) plan Submission [Any increase in area to be computed under item (1) or (2)] | No. of Storey | $400/storey |
6 | Amendment / Deviation to Approved Plan [Any increase in area to be computed under item (1) or (2)] | No. of Storey | $200/storey |
7 | Demolition of Entire Building | No. of Storey | $200/storey |
Height of Building (m) | $200 for every 5 metres or part thereof the building |
