Clear height and floor load capacity are the two invisible parameters that decide whether a factory works for your sector, and neither can be verified by eye on a site visit. A wrong load figure in a brochure can lead a tenant to sign for a factory its heaviest production line cannot be placed in. This article shows how to verify technical parameters from design documentation and lock them into the lease as landlord commitments.
A factory’s technical parameters differ from every other term in that their errors surface only after machinery is in position — the moment every cost is already sunk. Verifying load capacity and height therefore cannot stop at a broker’s introduction; it must reach the as-built file, structural design drawings and an actual measurement record. The locking file for this step is a technical-parameter annex signed by the landlord, turning advertising numbers into contract commitments.
Legal basis in force for this topic (checked on 20 October 2026)
The foundation remains the asset lease contract under the 2015 Civil Code (Law No. 91/2015/QH13): Article 472 establishes the asset lease contract, Article 475 allows subleasing with the lessor’s consent, and rent, term and payment method are agreed by the parties within the limits of the law. On that foundation, a factory’s technical parameters form part of the description of the leased asset: once the landlord commits load capacity and height figures in the contract, any deviation becomes a leased-asset quality issue rather than an advertising matter.
The right to lease factories inside industrial parks derives from the 2024 Law on Land (Law No. 31/2024/QH15, in force from 1 August 2024) through the land-rent payment form in the land lease with the infrastructure company, and houses and works put into lease business must satisfy the 2023 Law on Real Estate Business (Law No. 29/2023/QH15, in force from 1 August 2024) on lawful ownership, no dispute and no seizure. Land-use and sublease violations are penalised under Decree 123/2024/ND-CP as amended by Decree 281/2026/ND-CP (in force from 31 August 2026), consolidated in Consolidated Text 73/2026/VBHN-BNNMT.
One technical point deserves care: design floor load and actual usable load are two different numbers, because an older factory floor may have lost bearing capacity after years of operation, alteration and loading. A tenant with heavy equipment or high-bay racking should require a current-state structural appraisal instead of reading only the original design file, and record the appraisal result as the basis of the parameter annex.
Analysis by practical question
For heavy machinery, how much floor load capacity is required? The right figure does not live in a universal tariff; it lives in that factory’s design documentation, set against the concentrated load of the heaviest equipment and the distributed load of the whole line. The tenant should require the landlord to supply the design load parameters from the as-built file, then have a structural engineer test them against the actual machine layout plan. Where equipment imposes large point loads — presses, moulding machines — load-spreading or local reinforcement must be planned at the factory-selection stage, not after the machines reach port.
How much clear height does a high-bay warehouse need? The clear height needed is decided by the racking system and handling equipment: the tenant must add planned rack height, forklift safety clearance and headroom for fire systems above. The detail most often missed is that the documented height is measured to the lowest point of structure — beams, pipes, sprinkler heads — not to the roof. The reliable verification is an on-site measurement, with the measured figure recorded in the parameter annex together with a cross-section drawing of the factory.
If the factory falls short, can it be reinforced? Technically, many shortfalls can be reinforced — strengthening foundations, adding load-bearing structure, redistributing loads — but legally and economically, reinforcing a leased asset is a separate project needing the landlord’s consent and possibly construction procedures of its own. The tenant needs an independent structural assessment before deciding, because reinforcing a floor for heavy machinery sometimes costs more than the rent difference of a factory that already meets standard. Every reinforcement deal must carry restoration and end-of-term cost-allocation clauses.
Roughly how much does reinforcement cost? Reinforcement cost depends entirely on the technical solution: load spreading with machine plinths is a different world from foundation strengthening or added columns and beams. A trustworthy figure comes only from contractor quotations built on the current-state structural appraisal. The tenant should obtain at least two independent quotations and add production-interruption cost during the reinforcement, the factor most often forgotten in the first budget.
Who do we ask for our sector’s requirements? Three sources must be combined: the factory’s design and as-built file for what the works actually have; equipment suppliers and line designers for what your sector actually needs; and an independent structural consultant to test the two sides against each other. The landlord and broker are sources of documents, not of technical conclusions, because they have a direct interest in letting the factory. The final conclusion should be a signed technical document from the appraisal unit, used as the basis for negotiation and for the contract annex.
