Industrial Land Due Diligence in Selangor: Zoning, Access, Drainage, Utilities and Approval Risk

Vacant industrial land removes the building, not the risk. The expensive questions sit under the surface and outside the boundary: title and zoning, legal heavy-vehicle access, stormwater discharge, deliverable utilities and pre-construction approvals. Investigate them before the offer becomes unconditional. This is general information, not property-specific legal, planning, engineering or environmental advice.

Keep title, zoning and planning permission as three separate tests

First, obtain a current official search and certified title copy. Check proprietor, tenure, lot area, land-use category, express conditions, restrictions, charges, caveats, leases and easements. JKPTG says the title records conditions and interests affecting land and that restrictions, caveats, charges or leases can require consent before transfer. Selangor’s Land and Mines Office provides e-Search and official-search services.

Second, establish statutory zoning. PLANMalaysia says a local plan contains a map and written land-use statement. i-Plan can screen cadastral lots, current use and zoning, but its disclaimer says gazetted plans and confirmation from PLANMalaysia State or the PBT prevail. Obtain the gazetted plan sheet, use-class table and written PBT interpretation for the lot and activity.

Third, map the development approvals. Section 19 of the Town and Country Planning Act 1976 prohibits development without planning permission, subject to limited exceptions. OSC 3.0 Plus separates planning, engineering and building plans, work notification and CCC deposition. Operator inference: an industrial title and zoning colour are not construction approval or permission for every process.

Make every conversion, planning or consent dependency a condition precedent. JKPTG’s 2024 circular covers section 124 applications to alter a category, express condition or restriction. Counsel and the registered town planner should identify the applicant, route, premium exposure, studies and failure outcome without promising approval.

Prove boundary, legal access and logistics geometry

Appoint a licensed land surveyor to reinstate the boundary and compare occupied ground, fences, drains, roads, utility corridors and structures with the title and certified survey information. Check for encroachment in both directions. Identify every easement, right of way, road reserve, acquisition line and utility reserve. If the lot relies on a private estate road, obtain the instrument granting access and the rules for maintenance, gate control, vehicle class and operating hours.

Then test the route from the controlling public road junction to the proposed guardhouse, loading yard and building platform. JPJ’s commercial-vehicle approval specification records overall dimensions, wheelbase, overhang, turning circles, axle ratings and design gross vehicle weight separately. Use the intended vehicle data in a swept-path study and check junction radii, road width, gradients, bridge and culvert limits, overhead obstructions, queue storage and safe turning.

Access also affects approvals. A current OSC planning-permission checklist published through KPKT’s platform includes location and layout plans, a land survey/contour plan and certification of access permission among submission documents; the responsible PBT and road authority determine the actual requirements for the lot. Ask a civil engineer and town planner to obtain written technical comments where a new access, road widening, drain crossing or traffic study may be required. Operator inference: frontage visible on a satellite image is not proof of a lawful, buildable or heavy-vehicle-capable entrance.

Treat water level, drainage and ground as design inputs

Start with a topographic survey tied to a recognised datum. Record spot levels across the lot, adjoining roads, drains, waterways and neighbouring platforms. Inspect after rain, look for ponding and silt lines, and obtain flood or drainage incident records where available. JPS describes its Flood Hazard Map as a hydrodynamic-modelling tool showing flood extent and depth for specified recurrence intervals; Public InfoBanjir separately publishes rainfall and river-level observations. Both are screening evidence, not a warranty that a particular lot will remain dry.

Require a civil engineer to identify the lawful outfall, catchment, downstream constraint, detention requirement, platform strategy and any reserve setback. JPS’s stormwater portal publishes MSMA 2nd Edition and separate checklists for planning permission, drainage plans, earthworks and erosion/silt control. Its MSMA service explains that the manual uses source control for stormwater quantity and quality and has been applied as a development-plan approval condition by government agencies. Do not accept “just raise the land” until the engineer assesses displaced storage, neighbouring impact, earthwork approval and the complete drainage system.

Investigate the ground, not only the surface. A geotechnical engineer should scope boreholes, laboratory tests and groundwater observations for the proposed platform, building loads, retaining works, pavements and tanks. An environmental consultant should review historical land use, fill source, dumping, neighbouring processes and contamination indicators before selecting soil or groundwater tests. DOE says prescribed activities under the 2015 EIA Order require EIA, while its January 2026 notice made the Pollution Prevention in Industrial Siting 2025 guideline the current replacement for the 2017 siting guideline. Obtain DOE’s project-specific screening or direction through qualified advisers.

Get utility feasibility in writing and reserve the land it consumes

Build utilities from process demand. Prepare electricity maximum demand and load characteristics; peak and daily water demand with pressure and quality requirements; sewer discharge quantity and characteristics; fire-water demand; telecommunications resilience; and any gas requirement. Send the same project description and layout to each provider so their replies address one scheme.

TNB says applications above 100A are submitted by a registered electrical consultant and may involve new substations. Its process requires approved development and site plans, load details and proposed substation information, and states that timing depends on load, location and local-authority approval. TNB’s 2025 connection-charge booklet also says certain load requirements require the consumer or developer to provide substation land. Ask TNB to confirm the connection concept, upstream work, site or wayleave need, charges and dependencies; a transmission line at the boundary is not an allocation of capacity.

Air Selangor’s developer process first identifies a suitable tapping source and considers pressure, pipe size and other technical factors. It then requires approved plans for the supply line, meter location and any pump station or reservoir. IWK states that it is SPAN’s certifying agency for sewerage-works approvals in Peninsular Malaysia. Obtain written feasibility from both, and plot tanks, pump rooms, treatment systems, sewer reserves and access on the land budget. Operator inference: gross acreage is not usable acreage once roads, drains, detention, utilities, buffers, setbacks and substation sites are drawn.

Build an approval matrix before fixing the land price

Ask the town planner to create an approval matrix with four columns: approval or technical input, lead consultant, prerequisite and decision authority. Depending on the site and operation, the matrix may include land matters, planning permission, earthworks, roads and drainage, building plans, landscape, utilities, sewerage, BOMBA input, DOE screening or EIA, and later CCC and operating licences. The OSC 3.0 Plus manual is a process framework; the PBT and technical agencies confirm the current submission route and documents.

Turn the matrix into deal controls. The offer should allow surveys, boreholes, environmental sampling and authority/utility inquiries; require the seller’s title and historical records; identify refundable deposits; and state which findings permit withdrawal, price adjustment or an extension. Do not make completion depend on a vague phrase such as “subject to authorities” while leaving the applicant, cost and acceptable conditions undefined.

Finally, price only the developable scheme. Include land conversion or consent exposure identified by counsel, earthworks, ground improvement, drainage and detention, road/access works, utility infrastructure, substation land, professional fees, authority contributions and environmental controls. Keep assumptions visible and label commercial judgments as inferences. Before commitment, have a licensed property lawyer, registered town planner, licensed surveyor, professional civil/geotechnical/electrical engineers and qualified environmental consultant sign off their scopes, and obtain written confirmation from the land office, PBT, JPS, DOE, TNB, Air Selangor, IWK and other relevant authorities.
