Extending a leased factory touches three layers of rights at once: the landlord’s rights over the works, the State’s construction management, and the tenant’s right of use inside the lease term. Building without a permit on someone else’s land is the fastest way to turn a capacity project into a penalty decision and a demolition order. This article sets out the permit sequence and how to allocate costs and ownership of the extension before breaking ground.
An extension is the strangest item in a lease relationship: the tenant pays to build on the landlord’s asset, yet permits and works documentation must stand on the owner’s underlying rights. Every agreement — who applies, who pays, who owns the added part at expiry — must be fixed in writing before construction starts, because once the structure stands, the tenant’s negotiating position nearly vanishes. The locking file for this step is a trio: the landlord’s consent, the construction permit, and the completion acceptance record.
Legal basis in force for this topic (checked on 20 October 2026)
The Law on Construction 50/2014/QH13 (amended and supplemented by Law 62/2020/QH14) governs construction investment, and its Article 89 lists the cases exempt from a construction permit alongside the cases that require one before breaking ground. New builds, area extensions and changes to a factory’s load-bearing structure usually fall in the permit-required group, so the tenant’s default assumption must be “no permit, no build”, unless the item verifiably falls inside an exemption confirmed in writing.
Project and quality management for the extension sits in two guiding decrees: Decree 15/2021/ND-CP on construction investment project management governs project management organisation, construction supervision and the capacity conditions of contractors and supervision consultants; Decree 06/2021/ND-CP details construction quality management, execution and maintenance, including completion acceptance of work items and of the whole works before exploitation and use. For an FDI tenant, these two frames are the basis for building its own supervision apparatus rather than leaving everything to the contractor.
The construction contract for the extension also sits under the 2015 Civil Code on contract formation and performance, including guarantees under Article 335, damages and breach handling; warranty retention money and sectional acceptance must be designed into the contract from the start. And because the extension stands on a leased factory, the lease needs its own annex recording the landlord’s consent and the fate of the added works when the lease ends.
Analysis by practical question
We lease the factory and want to extend it — how do we proceed? The safe sequence runs in four interlocking steps: obtain the landlord’s written consent with the proposed drawings; determine whether the item requires a construction permit under Article 89 of the Law on Construction; file the permit application under the appropriate named subject and start work only after the permit issues; then supervise and complete acceptance under Decree 06/2021/ND-CP before putting the extension into use. Skipping any step puts the risk not on the schedule but on a possible stop-work or demolition outcome for what was already built.
Who applies for the permit: the landlord or the tenant? The named applicant must attach to the rights over the works and the land, so inside a lease the file usually needs the landlord as applicant or co-applicant, authorising the tenant to run the procedure. A tenant should not put the whole file in its own name over an asset it does not own, because the permit and as-built records become part of the works documentation belonging to the landlord. This allocation — who signs, who files, who keeps the original as-built file — belongs in the extension consent annex right away.
Who bears the extension cost? In practice the tenant bears the cost by default because the extension serves the tenant’s production needs, but this is a negotiation point, not a rigid rule. If the extension raises the factory’s long-term value and stays with the landlord after expiry, the tenant has grounds to negotiate cost sharing, or an exchange for reduced rent or a longer term. Any sharing deal must tie to settlement mechanics and acceptance records, so that overruns outside the budget do not end up unowned.
When the lease ends, who owns the extension? An extension integrated with the main works normally becomes part of the landlord’s real estate when the lease ends, unless the parties agreed the tenant may remove it, take it away, or be compensated for residual value. This clause must be settled before building, with a valuation formula for any compensation. A tenant who builds first and asks later usually receives the least favourable default outcome: losing the entire value invested in the extension.
What happens if we build without a permit? Building without a permit, or not in accordance with one, on a leased factory can draw administrative penalties in the construction field, a stop-work order and, in serious cases, demolition of the violating part to restore the original state. The risk does not stop at fines: an unpermitted structure has no valid as-built file, which complicates fire acceptance, location registration and customer or partner audits. For an FDI tenant, one unpermitted extension can collapse the plant’s entire compliance schedule.
A safe implementation sequence
- Assign a single owner to follow expanding a leased factory extensions mezzanine floors permit procedures after completion day, because reporting, renewal and incident duties of expanding a leased factory extensions mezzanine floors permit procedures usually arrive much later than the signing date of expanding a leased factory extensions mezzanine floors permit procedures.
- Fix the budget and a weekly timetable for expanding a leased factory extensions mezzanine floors permit procedures, separating domestic payments, items dependent on authorities, and a contingency for supplementary rounds on expanding a leased factory extensions mezzanine floors permit procedures.
