Pre-Lease Due Diligence Checklist: 25 Things to Verify Before Signing

Introduction

Signing a commercial office lease is a long-term business commitment, not just a real estate transaction. Before finalising any agreement, conducting thorough office lease due diligence helps identify legal, operational and infrastructure risks that could affect costs, timelines and day-to-day business operations.

A workspace may appear ideal during a site visit but still have hidden issues such as limited power capacity, poor HVAC performance, inadequate parking, restricted fit-out permissions or missing statutory approvals. Discovering these after signing the lease often leads to expensive modifications and unnecessary delays.

This guide outlines the 25 essential checks every occupier should complete before leasing office space in Gurgaon, helping businesses evaluate properties with greater confidence and avoid costly surprises later.

Why Office Lease Due Diligence Matters

An impressive reception area or a competitive rental quote rarely tells the full story.

Many challenges only become visible after the lease is signed, when workplace design, fit-out work or employee onboarding begins. At that stage, resolving infrastructure or compliance issues is usually more expensive and time-consuming.

A structured due diligence process helps businesses:

• Verify that the building complies with statutory regulations

• Identify infrastructure limitations before fit-out begins

• Estimate the actual cost of occupancy

• Reduce project delays during office setup

• Improve workplace efficiency and employee experience

• Strengthen negotiating power before signing the lease

The objective isn't simply to secure office space. It's to ensure the workplace supports your business from the day your team moves in.

The 25-Point Office Lease Due Diligence Checklist

Evaluating an office involves far more than comparing rent across different buildings.

An effective due diligence process should assess every property across five core areas:

1. Building & Infrastructure

2. Legal & Compliance

3. Workplace Operations

4. Commercial & Financial Terms

5. Future Business Requirements

Together, these categories provide a complete picture of how suitable the office will be over the entire lease period.

Building & Infrastructure Checks

Physical infrastructure directly impacts employee comfort, operational continuity, and future expansion. Even Grade A commercial buildings can differ significantly in engineering systems, maintenance standards, and workplace efficiency.

1. HVAC Capacity

Heating, ventilation and air conditioning influence far more than workplace comfort. An undersized or poorly maintained system can affect productivity, increase maintenance costs and create inconsistent temperatures across the office.

Verify:

• Installed HVAC capacity

• Operating hours

• After-hours cooling policy

• Fresh air circulation

• Maintenance responsibility

• Areas with uneven airflow

If your office will include server rooms, trading floors or densely occupied collaboration zones, confirm that cooling capacity aligns with the expected occupancy.

2. Fire NOC and Fire Safety Compliance

Every commercial office should have valid fire safety approvals before occupation.

Request copies of:

• Fire No Objection Certificate (NOC)

• Fire evacuation plans

• Sprinkler inspection records

• Fire alarm maintenance reports

• Emergency exit layouts

During the site visit, inspect emergency exits, refuge areas, extinguishers and evacuation signage rather than relying solely on documentation.

3. Electrical Power Load

Many occupiers only discover electrical limitations once workplace construction begins.

Before signing the lease, confirm:

• Sanctioned electrical load

• Available spare capacity

• Diesel generator backup

• UPS compatibility

• Separate metering arrangements

• Capacity for future expansion

Businesses operating high-density workstations, meeting rooms or specialised equipment typically require higher power availability than standard office users.

4. Lift Capacity and Lift Ratios

Lift performance has a noticeable effect on the everyday employee experience, particularly during peak office hours.

Assess:

• Number of passenger lifts

• Service lift availability

• Lift-to-occupant ratio

• Average waiting times

• Maintenance schedule

A premium office building should support efficient movement without creating bottlenecks during arrival, lunch or closing hours.

5. Internet Service Providers

Reliable connectivity is now a business necessity rather than an added advantage.

Before committing to a property, verify:

• Available fibre providers

• Redundant internet connections

• Dedicated leased line availability

• Building permissions for new providers

• Typical installation timelines

Buildings supported by multiple telecom operators generally offer greater operational resilience.

6. Parking Availability

Parking becomes a daily operational issue if it isn't assessed during the leasing stage.

Review:

• Employee parking allocation

• Visitor parking

• Two-wheeler parking

• EV charging facilities

• Additional parking availability

• Associated parking charges

If client meetings are frequent, visitor parking should carry as much importance as employee parking.

7. Floor Plate Efficiency

Two offices with the same quoted area can offer very different levels of usable workspace.

Assess:

• Carpet area efficiency

• Column placement

• Natural daylight

• Core positioning

• Workspace planning flexibility

Efficient floor plates usually reduce fit-out costs while allowing better workstation density and collaboration spaces.

8. Building Age and Maintenance Standards

Age alone isn't an indicator of quality. Ongoing maintenance is far more important.

Review:

• Recent capital upgrades

• Condition of common areas

• HVAC servicing records

• Electrical infrastructure

• Plumbing systems

• Preventive maintenance schedule

Buildings with consistent maintenance programmes generally perform better over long lease periods.

9. Water Supply and Plumbing

Water infrastructure is often overlooked until operational issues arise.

Confirm:

• Water availability

• Storage capacity

• Pantry plumbing

• Washroom condition

• Drainage systems

This becomes especially important for offices with larger employee populations.

10. Building Security Systems

Security should extend well beyond reception personnel.

Evaluate:

• CCTV coverage

• Access control systems

• Visitor management process

• Boom barriers

• Security staffing

• Emergency response procedures

Businesses handling confidential information or sensitive client data should review building security standards in greater detail.

Legal & Compliance Verification

Commercial negotiations should never move ahead without confirming that the building meets all legal and regulatory requirements.

11. Property Ownership

Confirm that the landlord has the legal authority to lease the premises.

Request:

• Ownership documents

• Title records

• Authorisation to lease

• Company ownership details, where applicable

Never rely solely on verbal confirmation or marketing material.

12. Occupancy Certificate (OC)

An Occupancy Certificate confirms that the building has been approved for occupation by the relevant authorities.

Request a copy of the valid certificate before signing any commercial agreement.

Without it, businesses may face avoidable legal or compliance issues after taking possession.

13. Statutory Building Approvals

Verify that all mandatory approvals remain valid.

These may include:

• Environmental approvals

• Municipal approvals

• Structural certifications

• Utility clearances

Missing documentation can delay occupancy, fit-out approvals or business operations.

14. Lease Agreement Review

The lease agreement deserves the same level of scrutiny as the property itself.

Review clauses covering:

• Lease tenure

• Lock-in period

• Rent escalation

• Security deposit

• Maintenance obligations

• Exit conditions

• Renewal options

• Restoration requirements

Having the agreement reviewed before execution can prevent disputes later in the lease term.

15. Insurance Responsibilities

Clarify which insurance policies remain the landlord's responsibility and which must be arranged by the tenant.

Typically, this includes:

• Building insurance

• Public liability

• Fit-out insurance

• Contents insurance

• Employee-related coverage

A clear understanding of insurance responsibilities helps avoid unnecessary gaps in protection.

16. Fit-Out Restrictions

Every commercial building follows its own fit-out guidelines, and these can significantly influence project timelines.

Before signing the lease, understand:

• Approved working hours for construction

• Contractor onboarding requirements

• Material movement procedures

• Freight lift availability

• Noise restrictions

• Fit-out approval timelines

• Security deposits for contractors

A building with restrictive fit-out policies may delay your office handover, even if the space is otherwise ready for occupation.

17. Delivery and Loading Access

Office construction and move-ins depend on efficient logistics.

Confirm:

• Loading bay availability

• Freight lift access

• Vehicle height restrictions

• Delivery time windows

• Parking for unloading

• Material storage provisions

Poor loading access often results in longer fit-out schedules and higher project costs.

18. Facility Management Standards

The quality of facility management has a direct impact on the day-to-day workplace experience.

Understand who manages the building and assess:

• Housekeeping standards

• Engineering support

• Preventive maintenance programmes

• Waste management

• Landscape maintenance

• Complaint response times

• Emergency support

A professionally managed building generally experiences fewer operational issues over the lease term.

19. Building Operating Hours

Not every commercial office provides unrestricted access.

Before signing, verify:

• Weekend accessibility

• Public holiday operations

• After-hours access

• Night shift permissions

• Visitor access policies

• HVAC availability beyond standard working hours

This is particularly important for businesses operating global teams, customer support functions or flexible work schedules.

20. Accessibility and Employee Convenience

A well-connected office contributes to employee satisfaction and improves business accessibility for clients.

Evaluate:

• Metro connectivity

• Public transport access

• Road connectivity

• Airport accessibility

• Nearby restaurants and cafés

• Banks and ATMs

• Healthcare facilities

• Hotels for visiting clients

Location should be assessed not only from a business perspective but also from the employee experience.

Financial & Commercial Due Diligence

The quoted rental rate rarely reflects the total cost of occupying an office. Understanding every commercial obligation before signing helps prevent unexpected expenses throughout the lease period.

21. Common Area Maintenance (CAM) Charges

CAM charges vary considerably between commercial buildings.

Clarify:

• Monthly CAM charges

• Services included

• Annual escalation

• Billing methodology

• Additional maintenance costs

Understanding CAM early makes it easier to compare two properties on a like-for-like basis.

22. Security Deposit Terms

Security deposits represent a significant upfront investment.

Review:

• Deposit amount

• Refund timeline

• Permitted deductions

• Adjustment conditions

• Documentation requirements

All financial obligations should be clearly documented within the lease agreement.

23. Lease Lock-In and Exit Clauses

Business requirements can change during the lease period.

Before signing, understand:

• Lock-in duration

• Notice period

• Early termination provisions

• Renewal rights

• Rent escalation schedule

• Exit obligations

Flexible lease terms often prove valuable for businesses expecting growth or organisational changes.

24. Restoration Obligations

Many commercial leases require tenants to restore the premises before vacating.

Clarify:

• Scope of restoration

• Responsibility for reinstatement

• Expected condition at handover

• Exceptions for landlord-approved alterations

• Estimated restoration costs

Exit obligations can have a substantial financial impact and should never be overlooked during negotiations.

25. Total Occupancy Cost

The rental figure is only one component of the overall financial commitment.

Calculate the complete cost of occupancy, including:

• Base rent

• CAM charges

• Parking fees

• Electricity

• Internet services

• Security deposit

• Interior fit-out

• Stamp duty

• Registration charges

• Facility management costs

Comparing offices based on total occupancy cost provides a far more accurate basis for decision-making than comparing rent alone.

Common Due Diligence Mistakes Businesses Make

Many office leasing challenges arise because due diligence begins too late or focuses only on commercial terms.

The most common mistakes include:

• Relying solely on broker information

• Skipping technical inspections

• Reviewing lease documents at the final stage

• Ignoring building operating policies

• Comparing offices only on rent

• Underestimating fit-out timelines

• Overlooking future expansion requirements

• Failing to involve legal, IT and facilities teams early

A structured due diligence process reduces uncertainty and helps businesses make better long-term decisions.

Quick Checklist

Before signing an office lease, confirm that you've reviewed:

✓ Property ownership
✓ Occupancy Certificate
✓ Fire NOC
✓ HVAC capacity
✓ Power load
✓ Lift ratios
✓ Internet providers
✓ Parking allocation
✓ CAM charges
✓ Lease agreement
✓ Fit-out policies
✓ Total occupancy cost

Traditional office leasing often requires businesses to coordinate multiple stakeholders, including brokers, architects, legal advisors, project managers, contractors and facility teams. While each plays an important role, managing them independently can slow decision-making, create communication gaps and delay project delivery.
