Canteens, parking sheds and guardhouses appear in every factory master plan, yet when they must be added or rebuilt they cause the most procedural confusion: with a project master permit in hand, does each small item need its own permit. The answer rests on a simple principle — a construction permit is issued for works under the appraised design dossier; an item inside the approved design is built under that permit, while an item outside the approved design is an unpermitted work however small it is and however fully it sits on the plant own land.
Items inside the approved design need no separate permit
Where the canteen, parking shed and guardhouse are inside the project design dossier and master plan appraised and licensed, they are built under that very permit like other work items, and no separate per-item permit procedure exists or is needed. The condition is building exactly at the approved position, scale and function; acceptance and as-built completion of these items travel with the whole-work acceptance chain.
Post-operation additions are the part needing handling: a new parking shed, a canteen extension or an extra guardhouse at a side gate all change the approved design. By degree, the investor must run construction permit amendment or license the added item before building, especially where the new item changes the master plan, building density or the site-wide fire solutions. Building on one own initiative because the area is small is how plants most commonly accumulate permit breaches in operation.
Is there an area threshold exempting ancillary items
Construction law sets a list of works exempt from construction permits by statutory character and scale, but there is no general square-metre threshold for canteens and parking sheds in an operating factory: a parking shed of a few hundred square metres is still a construction work that must be covered by the project permit or by amendment and supplementary licensing. Temporary, demountable short-term items may follow the temporary work regime where conditions are met, but the temporary label should not dress up long-term items.
The only safe exemption boundary is minor repairs and renovations not changing load-bearing structure, function or scale and not affecting safety or environment under the statutory list. Re-roofing a parking shed with the same materials and scale is maintenance; erecting a new shed frame and concreting an expanded parking area is new construction needing a permit basis. In grey zones, a written question to the permitting authority or the park management board is the cheapest cost against a later demolition decision.
Fire requirements for canteens and parking, and handling out-of-design building
A parking shed is a high fire-risk item for concentrated fuel-carrying vehicles and e-bike batteries, and a canteen concentrates crowds with a gas and heat kitchen zone: by scale and character these items fall under fire design appraisal or under fire management with requirements on escape routes, safety distances and on-site extinguishing means under applicable standards. A new ancillary item design must be checked in sync with the plant overall fire solutions rather than handled in isolation, because one misplaced parking shed can break the fire safety distances of a whole zone.
Items already built outside the approved design are handled under the permit-breach and unlicensed framework of Decree 339/2026/ND-CP: fines, forced demolition of the built part where conditions fail, or amendment and supplementary licensing to stand where the item matches planning, land use indicators and passes safety and fire assessment. Handling should ride on the plant periodic master plan review to gather all accumulated deviations into one resolution, instead of letting each small item become a separate case across inspection rounds.
Frequently Asked Questions
With a master permit in place, do canteens and parking sheds inside the campus need separate permits?
No, if the items are inside the licensed design dossier and master plan, they are built under that master permit. Only additions, extensions or items outside the approved design need permit amendment or licensing of the added item before building, especially where the master plan, building density or site-wide fire solutions change.
Below what area are ancillary items permit-exempt?
There is no general square-metre threshold for canteens and parking sheds in a factory. Exemption follows the statutory list, typically minor repairs not changing load-bearing structure, function or scale while ensuring safety and environment. A new parking frame or canteen extension is new construction needing a permit basis via the master permit, amendment or supplementary licensing, however small.
Do parking sheds and canteens need separate fire appraisal?
It depends on scale and character: items in the fire design appraisal group must be appraised and fire-accepted; items in the fire management group must meet escape, safety distance and on-site extinguishing requirements. Parking with many vehicles and e-bike batteries and canteens with gas kitchens are high-risk groups, and designs must sync with the plant overall fire solutions.
How are added ancillary items outside the approved design handled?
As unlicensed or breach construction under Decree 339/2026/ND-CP: fines and demolition where standing conditions fail; where the item matches planning, land use indicators and passes safety and fire assessment, amendment and supplementary licensing can let it stand. Gather the handling into the plant periodic master plan review.
