Commercial Property Due Diligence Checklist Singapore: 12 Steps Before You Commit

Buying commercial property in Singapore is not a bigger version of buying a home. The stakes are different: the wrong zoning, a disputed title, a leaking sinking fund or an unapproved alteration can turn an owner-occupied asset into a liability that drains cash flow for years. This checklist is built for first-time commercial buyers and SMEs who plan to use the space themselves, but most of it also applies if you are buying tenanted.

The goal is simple: before you pay the option fee or exercise the sale, confirm that the property can legally do what your business needs it to do, that the numbers you are underwriting are real, and that no hidden cost or compliance gap is waiting to surface after completion. Due diligence will not eliminate risk, but it will price it correctly — or tell you to walk away.

What This Checklist Covers

The 12 steps are grouped into four workstreams that mirror how a disciplined buyer approaches a commercial acquisition:

• Title and tenure verification — what you actually own and what you can use it for.
• Financial due diligence — whether the income, outgoings and reserves support the price.
• Physical and compliance checks — whether the building is safe, accessible and legally altered.
• Professional team assembly — who does what, and when to bring them in.

1. Title and Tenure Verification

Step 1: Confirm ownership and encumbrances

Your lawyer should obtain an official IRAS/URA title search and review the title deed. You need to know:

• Whether the seller is the registered owner and has the right to sell.
• Whether the title is freehold, 999-year leasehold or 99-year leasehold, and how many years remain.
• Whether there are mortgages, caveats, charging orders or other encumbrances that must be discharged before completion.
• For strata-titled units, whether there are outstanding contributions owed to the Management Corporation Strata Title (MCST).

Red flag: A caveat from a third party, an unresolved probate dispute or a seller who cannot produce a clean title chain should stop the deal until cleared.

Step 2: Verify URA zoning and plot ratio

The Urban Redevelopment Authority (URA) Master Plan governs what can be built and used on the site. Check:

• The zoning of the plot — commercial, residential, industrial, mixed-use or institutional.
• The plot ratio (PR), which determines how much gross floor area (GFA) can be built relative to land size.
• Whether the current building already uses its full allowable GFA or whether there is untapped development potential.
• Any buffer zones, road reserves, conservation status or height controls that affect future expansion.

For owner-occupiers, this matters because a change in URA zoning can change the future value of the asset and your ability to expand. Do not rely on the agent's verbal summary — pull the URA Master Plan and, if needed, a planning consultant's written opinion.

Step 3: Match approved use to your business activity

URA's approved use must allow your intended operations. A unit in a B1 industrial building, for example, cannot be used for heavier manufacturing that requires B2 zoning. Retail, F&B, office, medical, education and logistics each carry different use-class requirements and change-of-use approval paths.

Action items:

• Check the URA property use approval for the unit.
• If you plan to change use, confirm whether it is permitted, conditional or prohibited, and budget for the application timeline.
• Review the building's by-laws and house rules for restrictions on signage, loading, operating hours and noise.

Red flag: A seller or tenant operating a use that does not match URA approval means you inherit the compliance risk.

2. Financial Due Diligence

Step 4: Reconstruct the rental history

Even if you plan to occupy the space, recent rental evidence tells you whether the price is underwritten by market income. Request:

• The last 24–36 months of rental statements or tenancy agreements.
• Any rental arrears, deposit forfeitures or tenant disputes.
• A comparison against similar units in the same building or district. You can browse comparables through our commercial and industrial property directory.

Step 5: Read every tenant lease carefully

If the property is tenanted, the lease is part of what you are buying. Your lawyer should review:

• Tenant name, lease term, rent, security deposit and expiry date.
• Renewal options, rent review clauses and break options.
• Whether the tenant has right of first refusal or assignment restrictions.
• Who pays property tax, maintenance, utilities and insurance.
• Any personal-indemnity or fit-out obligations that transfer to you as landlord.

Red flag: A tenant with a below-market rent and a long unexpired term drags down your yield and may block owner occupation.

Step 6: Audit management charges and sinking fund health

For strata commercial properties, monthly management charges and the sinking fund can materially affect your net operating income. Request:

• The latest management corporation financial statements.
• Current management charge psf and any special levies planned or under discussion.
• The sinking fund balance and the schedule of major repairs or upgrades coming due.
• The ratio of owner-occupiers to investors, which affects voting dynamics in the MCST.

Red flag: A sinking fund that is underfunded relative to the building's age, or a pending lift, facade or fire-system upgrade, can mean a six-figure special levy within your first few years of ownership.

3. Physical and Compliance Checks

Step 7: Commission a physical condition survey

Do not rely on the viewing photos. Engage a qualified inspector or quantity surveyor to assess:

• Structural integrity, cracks, water ingress and roof condition.
• Air-conditioning, electrical, plumbing and lift systems.
• Floor loading, ceiling height and column spacing against your operational needs.
• Common areas, access roads, loading bays and parking allocation.

Step 8: Confirm fire safety and accessibility compliance

The Singapore Civil Defence Force (SCDF) regulates fire safety. Check:

• Whether the building has a valid Fire Safety Certificate and when it expires.
• Whether the unit's fire protection systems — sprinklers, alarms, hose reels, extinguishers — are maintained and tested.
• Whether your intended fit-out requires a Fire Safety Plan or Building and Construction Authority (BCA) approval.
• Accessibility compliance under the Building Control Act for persons with disabilities, especially if the public will access the premises.

Step 9: Verify renovation and alteration approvals

Any previous renovation must have the right approvals. Ask for:

• BCA renovation permits and certificates of statutory completion.
• Approved plans for partition walls, mechanical works, signage and facade changes.
• Whether any works encroach into common property or affect structural elements.

Red flag: Unapproved alterations can trigger enforcement orders, require reinstatement and invalidate insurance claims.

Step 10: Screen for environmental and hazardous-material liabilities

Industrial and older commercial buildings can carry environmental risks. For manufacturing, workshops, laboratories or F&B, investigate:

• Previous uses of the site and whether any hazardous substances were stored or processed.
• Soil and groundwater contamination history, especially for former industrial sites.
• Whether asbestos, lead paint or other regulated materials are present in older buildings.
• Waste-water discharge, exhaust and ventilation requirements for your operations.

Environmental liability can stick to the current owner even if the contamination happened decades ago. If in doubt, commission a Phase I environmental site assessment.

4. Assemble Your Professional Team

Step 11: Engage the right lawyer

Use a lawyer who handles commercial conveyancing, not just residential. They should deliver:

• A clean title report and advice on tenure, encumbrances and restrictions.
• Drafting or review of the Option to Purchase (OTP) and Sale & Purchase Agreement.
• Review of leases, licences, MCST by-laws and any existing disputes.
• Calculation of stamp duties, including Buyer's Stamp Duty (BSD), Seller's Stamp Duty (SSD) timelines if relevant, and Goods and Services Tax (GST) applicability.

Step 12: Add a quantity surveyor and property advisor

For larger acquisitions or properties needing refurbishment, a quantity surveyor (QS) estimates reinstatement, renovation and lifecycle costs. A commercial property advisor provides comparable transaction data, negotiation strategy and market context.

Red Flags That Should Pause or Kill the Deal

• The seller cannot produce a clean title or delays providing title documents.
• URA zoning or approved use does not match your business activity.
• A major tenant is paying well below market rent with years left on the lease.
• The MCST has approved a special levy but has not disclosed the amount.
• There are unapproved structural or fire-safety alterations.
• The building has a history of environmental complaints or contamination.
• The asking price is unsupported by comparable transactions in the area.

Bottom Line: Who This Suits, and Who Should Reconsider

This checklist is designed for SMEs and first-time commercial buyers who want to own the space they operate from. It is also useful for small investors buying a single tenanted unit. If you complete these 12 steps, you will enter the transaction with a clear view of legal tenure, financial reality, physical condition and compliance exposure.

However, commercial property is illiquid, and owner-occupation ties your balance sheet to your business location. If your company may relocate within three to five years, or if your cash flow cannot absorb a special levy, renovation or vacancy period, leasing may be the more prudent option.

Your Next Step

Due diligence is not a formality — it is the process that turns a guess into an informed decision. Start with zoning and title, then move to financials, physical condition and your professional team. If you would like a second opinion on a specific commercial or industrial property, speak with Cindy to review the deal before you commit.
