Should You Build to Suit or Lease a Ready-Built Factory?

October 30, 2026

A ready-built factory is faster and lower risk. A built-to-suit factory fits your process better and costs you time and a longer commitment. For most first-time tenants in southern Vietnam, a ready-built unit is the better start. A custom build makes sense when your process cannot fit a standard shell, when you need a large area on one site, or when you are ready to commit for ten years or more.

What each option means

Ready-built. The developer or owner built the shell before finding a tenant. You inspect it, sign a lease and fit it out. The spec is fixed: clear height, column grid, floor load, transformer and docks are already there.

Built to suit (BTS). You give the developer a specification. The developer designs, permits and builds the factory on land it controls inside an industrial park, then leases it to you. The developer owns the building and often recovers the cost through rent over a long term.

There is also a middle path: a ready-built unit with landlord upgrades. The landlord adds a crane, extra docks or a bigger transformer and recovers the cost in the rent. It is quicker than a full build and covers many gaps.

Side-by-side comparison

Point	Ready-built	Built to suit
Time to handover	Weeks to a few months	Often a year or more, including design and permits
Fit to your process	Must be checked, may need upgrades	Designed around your layout
Typical lease term	About 3 years minimum, longer for large units	Often 10 years or more
Upfront cash	Deposit and fit-out	Deposit, and often larger security and fit-out
Exit flexibility	Easier, units re-let quickly	Harder, a custom building is hard to re-let
Rent	Listed range, negotiable	Set by project cost and term
Permit risk	Mostly already done	Construction and fire permits are part of the schedule

Treat the time and term rows as planning figures. Each developer sets its own, and you should get them in writing.

When ready-built is the right choice

• You need to start production in months. A customer is waiting, or you are moving orders out of another country.
• Your process fits a standard shell. Assembly, packing, light machining and many plastics and electronics lines run well in 8 to 10 m clear height with a 2 to 3 ton per m² floor.
• Volumes are uncertain. A three-year lease lets you test the market without a ten-year promise.
• You want a lower cash commitment. The money goes into machines, not into a building.

The ready-built factory checklist shows how to test whether a unit fits.

When built to suit is worth it

• Your process needs a spec that does not exist. Examples are very high clear height, heavy floor loads for large presses, a long crane runway or a layout that follows a continuous line.
• You need a large area on one site. If you need 15,000 m² or more in one building, there may be no standard unit available. See our guide to large factories for rent.
• You plan to stay ten years or more. The longer commitment is then acceptable and gives you a building made for the job.
• You need fire, hygiene or cleanroom features built in. Retrofitting is costly in an old shell.

The costs that surprise tenants

The longer minimum term. A custom building is hard for the landlord to re-let, so the landlord wants the term to repay the build. A short exit will cost a lot or may not be offered.

Change orders. If you alter the specification during design or construction, the cost and the schedule move. Freeze the specification early and agree how changes are priced.

Handover risk. The lease should say what happens if the building is late: a rent-free period that grows with each month of delay is a common way to deal with this. Ask for the construction schedule as an exhibit to the lease.

Permits. The developer usually handles the construction permit. Fire prevention design review and acceptance must be passed before you can operate. Check who is responsible and what happens if acceptance is delayed.

A step-by-step way to decide

1. Write your hard specs. Floor area, clear height, floor load, kVA, crane and docks. Mark each as “must have” or “nice to have”.
2. Search the ready-built market first. If two or three units meet every “must have”, the case for building is weak.
3. Price the gap. If a ready-built unit lacks one item, ask for a landlord upgrade and see the rent change.
4. Compare total cost over the term. Add rent, fit-out and the cost of waiting. One extra year without production can cost more than the rent difference.
5. Decide the term you can live with. If you cannot commit for ten years, start ready-built.

A staged approach

Many tenants do both. They lease a standard unit for the first three to five years, run the process, learn what spec they really need, and then plan a custom building with real data. The first lease should include a renewal option or a notice period that fits the timeline of the second project. This keeps cash low at the start and gives you a better brief later.

What a built-to-suit lease should say

A custom building is only as safe as the contract. Before you sign, make sure the documents cover:

• The specification. Clear height, column grid, floor load, power, crane, docks, office and utilities, listed as an exhibit with tolerances.
• The schedule. Dates for design approval, permits, construction milestones and handover, with the remedy for delay.
• Acceptance tests. How you inspect and accept the building, and how defects are fixed after handover.
• Rent start. Rent should start on handover, not on signing.
• Change orders. How changes are priced, approved and recorded.
• Term and exit. The minimum term, break rights, renewal and what happens to the building at the end.
• Handback. Whether you must remove your fit-out and return the building in its original state.

Ask a Vietnamese lawyer to review the contract. A mistake in a long-term lease is costly to fix.

How a project usually runs

1. Brief and site. You give your specification and the developer offers a plot and a concept.
2. Heads of terms. Rent formula, term, deposit and key dates are agreed in a short document.
3. Design and permits. The developer designs and applies for the construction permit and fire prevention design review.
4. Construction. You get progress reports and, ideally, site visits.
5. Acceptance. Fire acceptance, utility connections and your own inspection.
6. Handover and fit-out. Your machines and furniture go in.

Each stage takes time, which is why a custom building starts later than a lease of a finished unit. Compare it against our setup timeline before you commit.

A note on rent and valuation

Landlords price a custom building from its cost and the term they can secure, so ask how the rent is built up. Some developers show the building cost, the land cost and a return, which lets you test the number. Others quote one figure. Whichever you get, ask what happens to the rent at renewal, and whether you can buy out the term. These two items often matter more than the starting rent.
