Management of State Land

Heritage Conservation

SLA plays a vital part in the conservation of heritage through the rejuvenation of State properties. In the process, economic and social value is unlocked for the State.

Land Reinstatement & Remediation

SLA also plays a crucial role in maintaining public health and safety, as well as environmental standards for State Land. This is done through the administering ofthe Land Reinstatement and Remediation Framework, which provides guidance on management of environmental issues in the land recycling process.

Technological Initiatives

SLA actively leverages on technology, geospatial information and analytics for better decision-making and service delivery in the management of State Land and Properties.

In line with the drive towards a Smart Nation, SLA is at the forefront of exploring, testing and implementing cutting-edge technology, with the goal of enhancing operational efficiency and productivity.

Find out more about some of our technological initiatives here:

1. SmartLAMD


2. Contractor’s App


3. Smart Unmanned Aerial Vehicles Enhanced (SUAVE) – Mainland Singapore

SLA operationalised the SUAVE flights in January 2018 to inspect State land and properties. Images captured from the UAV are analysed using advanced image analytics to automatically detect issues that require follow up, such as building defects, debris and water-ponding. 

Maintenance issues can now be detected automatically and comprehensively for SLA officers to follow up promptly.  This saves time and eliminates safety risks for officers conducting physical inspections at possibly inaccessible and dangerous sites.

4. Smart Unmanned Aerial Vehicles Enhanced (SUAVE) – Offshore Islands

SLA has also been looking to use fully automated UAV system to perform scheduled inspections on offshore islands under its care. 

Fully automated UAVs which fly using pre-planned waypoints and predefined flight schedules will obtain images and videos of the subject islands at scheduled timings. 

The UAVs are able to capture real-time images and videos which can be analysed to detect maintenance issues. This allows our officers to stay attuned to ground conditions, enabling them to provide prompt and quality service delivery. The trial has been completed and SLA is working with CAAS and MOT to implement the system.

5. Remote Utilities Monitoring (RUM)

SLA manages several offshore islands which do not have direct supply of utilities. This results in a need to constantly monitor the levels of the water storage tank and diesel tank, which helps ensure timely replenishment and prevents disruption of water and power supply.  

RUM uses smart meters to actively monitor utilities supply and consumption rate, thereby eliminating the need for officers to travel between islands to check on the water and diesel levels manually. The monitoring function not only sends replenishment alerts to officers to ensure a constant supply of fresh water and electricity to visitors on the islands, but also allows SLA to discern normal usage from wastage at the various endpoints where the smart meters are deployed. 

Encroachment and Enforcement

As the custodian of State Land and Property, SLA is responsible for safeguarding them against misuse. To do this, SLA officers attend to reported cases of encroachment or feedback. This is followed by investigation and enforcement of rules, if necessary.

What constitutes encroachment onto State Land? An encroachment onto State Land occurs when physical structures from private land extend onto State Land.

The use and/or occupation of State Land without permission also constitutes encroachment.

Are outdoor refreshment/ display areas operating on State land considered encroachments? Yes. Shops selling food, beverage, merchandise, etc are required to confine their business activities (including those sitting and display areas) within the business premises which they own / have leased.

Operators must obtain planning permission from URA for outdoor refreshment/display areas on State land first and then apply to SLA for a Temporary Occupation Licence (TOL) for the use of the State land (Hyperlink to rental of state lane page). 

What does SLA do after detecting an encroachment?
SLA will require the removal of encroachments The encroacher will need to bear the costs of removal.

If the encroacher fails to do so, enforcement action will be taken in accordance with the State Lands Encroachments Act.  

What can I do to verify if my property is encroaching on State land?
Property owners may wish to engage registered land surveyors to verify that there are no encroachments from their property on State land. 


What should I do if encroachment on State land is found stemming from my property after a survey?

You can write in to SLA to find out whether the encroachment can be regularised or it has to be removed.

For property owners whose buildings have projections or features encroaching onto State land, how can the encroachments be regularised?
SLA will follow up to consult the relevant agencies. If there are no objections from them, the encroachment does not pose any safety issues, inconveniences or negative externalities to the public, and does not pose any constraint to future development, we will allow the encroachment to be regularised. Depending on the extent of the encroachment, they can be regularised as follows:

  • For encroachments of 3-10cm , the owner of the encroaching property will be required to lodge a letter of undertaking with SLA to undertake the removal of encroachments as and when the State land is required for developments and to reinstate the affected State land to our satisfaction. 

  • For encroachments of more than 10cm, the owner of the encroaching property is required to take up a Temporary Occupation Licence (TOL) for the State land occupied by the encroachments and pay the requisite TOL fees. 

 SLA will also enter a notification of the encroachments in the land register so that successive owners of the encroaching property are notified of the existing encroachments onto State land.

State Land is a precious resource for all Singaporeans and must be managed responsibly. Here is a list of DOs and DON’Ts that we should follow:

Planting and farming on State Land may attract pests and create inconveniences to other people. Do check with your nearest Community Centre for venues allocated for these activities.

For property owners. Do ensure that the fencing around your property does not obstruct footpaths or extend beyond your property’s boundaries.

For property owners. When carrying out construction work, do engage a Registered Surveyor to ensure that all works are confined within your property’s boundary.

Don’t place or store items on State land, especially in back-lanes, as it would obstruct cleaning and rescue efforts should an emergency arise.

Don’t fence up back-lanes on State Land, as they provide access to utilities and emergency vehicles.
