Sometimes, yes, but only on specific sites, and the restriction is unusually tight compared to most other industrial uses. JTC’s own guidance for self-storage providers states plainly that Business 2 zoned sites on JTC land are not eligible for self-storage use at all, and that Business 1 sites carry a further carve-out: a published map of B1 sites reserved for clean and light manufacturing excludes self-storage even there.[1] A warehouse operator or a light-manufacturing tenant doesn’t face this kind of site-by-site exclusion. A self-storage operator does.
This matters to an operator shortlisting a unit for a new facility, an existing self-storage business on JTC land trying to work out whether its site is at risk when the lease comes up for renewal, and a landlord or buyer evaluating whether a property’s zoning can actually support self-storage use before marketing it that way. What follows is where self-storage sits relative to URA’s B1/B2 framework, why JTC treats it more restrictively than ordinary warehousing, the quantum and approved-use checks that still apply on top of the site question, and what the April 2025 policy change actually changed.
Self-Storage Is Not Just “Warehousing” for Zoning Purposes
URA’s planning framework treats storage and warehousing as a named B1 allowable use, and most general storage operations fit that category without special scrutiny.[2] Self-storage, however, is treated differently by JTC once the land is JTC-owned or JTC-leased, because the business model itself, renting out subdivided storage units directly to the public and to small businesses, changes the character of the use from industrial storage to something closer to a consumer-facing service running on industrial land. That distinction is why JTC’s self-storage guidance exists as a separate, more restrictive track rather than folding into the general warehousing rules.[1]
On JTC land specifically, the rule is a direct exclusion, not a case-by-case nuisance assessment: B2 sites, reserved for general industrial uses that typically involve heavier manufacturing activity, are not eligible for self-storage use under any circumstance.[1] Business Park sites carry the same exclusion. That leaves B1 as the only zoning category where self-storage is even considered, and even there it isn’t automatic.
The B1 Reserved-Sites Map Is the First Thing to Check
Not every B1 site on JTC land is open to self-storage. JTC maintains a map identifying B1 sites reserved for clean and light manufacturing activity, precision engineering, electronics assembly, and similar light-industrial uses, and self-storage use is disallowed on those reserved sites regardless of what else the zoning permits.[1] A B1 property outside that reserved footprint goes through case-by-case assessment weighing planning considerations and the approvals required from other agencies such as NEA and LTA.[1]
This is the detail an operator or buyer most commonly skips: confirming a site carries a B1 label is not the same as confirming it sits outside JTC’s reserved-sites map. The two checks are separate, and only JTC (for JTC land) or URA (for privately held B1 land not on the reserved map) can confirm the second one for a specific address.
What Changed in April 2025
JTC held a moratorium on new change-of-use applications to self-storage on its industrial land from late 2021, a response to rapid, largely unplanned growth of self-storage facilities on sites meant for manufacturing tenants. That moratorium lifted on 1 April 2025, reopening change-of-use applications for self-storage on B1 sites outside the reserved map, subject to the same case-by-case assessment and other agencies’ sign-off described above.[1]
The policy reset also has consequences for operators who moved in during or around the moratorium period. JTC has said existing self-storage facilities on JTC land will be allowed to continue operating until the end of their current lease or sublet term, which protects current occupiers in the near term without guaranteeing renewal.[1] Operators sitting on sites that fall inside a reserved B1 area, or that were originally zoned B2 or Business Park, should plan around the likelihood that a lease renewal at the same site for the same use will not be straightforward, rather than assume continuity.
The 60:40 Quantum Control Still Applies
Clearing the site-eligibility question doesn’t remove the standard URA quantum control that applies to industrial buildings generally: a defined majority of a development’s gross floor area has to be given over to core industrial or production-type activity, with the remainder available for ancillary functions such as offices, reception counters, or staff facilities.[1][3] For a self-storage facility, the storage units themselves count as the core use; the walk-in reception desk, retail counter for boxes and packing supplies, and back-office space have to stay inside the ancillary allowance rather than expand past it. An operator building out a large customer-facing showroom or retail frontage on top of the storage floor risks tripping this quantum control even on a site where self-storage use itself is permitted.
Change of Use Still Needs Confirming Before Fit-Out
A change-of-use application goes to URA for evaluation unless the premises already carries an approved use covering warehouse or storage operations.[1][4] Confirm the specific unit’s recorded approved use through URA’s Enquiry on Approved Use of Premises rather than relying on the building’s general B1 label or a previous tenant’s description of the space, since approved use is recorded per unit, not per building.[5] If the existing approved use doesn’t already cover storage/warehousing, a change-of-use application has to clear, with JTC’s additional self-storage eligibility check layered on top where the land is JTC-held.
What Doesn’t Change: Fire Safety and Hazardous-Item Exclusions
Two constraints apply to a self-storage facility regardless of which zoning question it clears.
Fire safety for a subdivided storage occupancy. A self-storage floor, partitioned into dozens or hundreds of individual lockable units with internal corridors, is a materially different fire safety submission from open-floor warehouse racking. SCDF’s Fire Code 2023 sets out requirements for storage occupancies under Purpose Group VIII, covering compartmentation, means of escape, and fire detection that a subdivided layout has to satisfy on its own terms, not by analogy to a single-tenant warehouse.[6] This submission needs to go in with the actual unit layout, not a generic warehouse fit-out plan.
No chemical or hazardous-item storage. URA’s B1 allowable-use entry for warehousing carries an explicit exclusion for chemical storage, and that exclusion carries straight through to self-storage.[2] This is also why every self-storage operator in Singapore maintains a list of prohibited items, flammables, chemicals, compressed gas, and similar hazardous goods, as a standard condition of use: it isn’t just a liability precaution, it’s the zoning condition the facility operates under.
| Scenario | Allowed? | What decides it |
|---|---|---|
| B2 or Business Park site (JTC land) | No | Excluded outright by JTC’s self-storage policy |
| B1 site inside JTC’s reserved clean/light-manufacturing map | No | Reserved for manufacturing tenants regardless of other factors |
| B1 site outside the reserved map | Case by case | Subject to planning assessment and NEA/LTA sign-off |
| Existing facility on a site now ineligible | Allowed until lease/sublet ends | No guarantee of renewal at the same site |
| Storage units plus large retail/showroom frontage | Depends | Must stay within the ancillary-use quantum allowance |
| Any self-storage facility, any eligible site | Hazardous items excluded | Same chemical-storage exclusion that applies to B1 warehousing |
Practical Checks Before Committing to a Site
- Confirm the site isn’t B2 or Business Park on JTC land. Both are excluded from self-storage use outright, independent of everything else.
- Check JTC’s reserved-sites map for a B1 address. A B1 label alone doesn’t confirm eligibility; the reserved-map status is a separate, binding check.
- Confirm the unit’s approved use through URA, rather than assuming a general B1 or warehouse zoning covers self-storage automatically.
- Model the floor plan against the 60:40 quantum control, especially if the business plan includes a significant retail or customer-service footprint.
- Brief the fire safety consultant on the actual subdivided-unit layout early, since SCDF’s assessment for a corridor-and-cubicle storage floor differs from a standard warehouse submission.
- Build the prohibited-items list into tenancy agreements from day one, consistent with the chemical-storage exclusion that applies to the use itself.
Caveats
JTC’s reserved-sites map and case-by-case assessment criteria are subject to review, and the April 2025 policy reset followed a multi-year moratorium, which suggests this is an area where guidance can shift again. Confirm current site eligibility directly with JTC’s cluster officer for JTC land, or with URA for non-JTC B1 land, before committing to a lease or acquisition built around self-storage use.
Takeaway
Self-storage faces a narrower path onto industrial land than almost any other B1-eligible use: B2 and Business Park sites are excluded outright, and even B1 sites split between a reserved manufacturing map and a case-by-case track for everything else. The April 2025 policy reset reopened that case-by-case track after a multi-year moratorium, but it didn’t remove the underlying site restriction, the 60:40 quantum control, or the standard change-of-use and approved-use checks that apply to any storage use. Confirm site eligibility before confirming anything else about a self-storage deal.
