Factory Plan Approval is a mandatory statutory requirement under Section 6 of the Factories Act, 1948 that requires the occupier of a factory to submit the building plans and specifications to the Chief Inspector of Factories or the State Factory Inspectorate for approval before constructing, extending, or taking into use any building as a factory. No factory construction can legally begin without this prior approval.
The approval process ensures that the proposed factory building complies with all health, safety, and welfare provisions prescribed under the Factories Act (Sections 11-20), the National Building Code (NBC), and applicable state-specific factory rules. The plans are scrutinised for adequate ventilation, lighting, fire safety, sanitary facilities, machinery spacing, structural stability, and environmental compliance.
The Factory Plan Approval process is the essential first step in the factory establishment process - it precedes the Factory License Registration, which is obtained only after the factory is constructed as per the approved plans and is ready for operations. Without plan approval, no Factory License can be issued, and any construction is treated as unauthorised under the Factories Act.
At IncorpX, we provide comprehensive assistance with Factory Plan Approval services across all states in India. Our team coordinates with licensed architects, structural engineers, and regulatory authorities to ensure your factory plans meet all statutory requirements and secure approval efficiently.
What is Factory Plan Approval?
Factory Plan Approval is the statutory process under Section 6 of the Factories Act, 1948 whereby the occupier of a proposed factory submits detailed building plans, site plans, machinery layout, ventilation designs, and specifications to the Chief Inspector of Factories for review and approval. The Chief Inspector evaluates the plans to ensure they comply with all provisions of the Factories Act relating to worker health, safety, welfare, and the National Building Code standards.
Section 6 specifically states that no person shall construct, extend, or take into use any building as a factory, or make any alteration that would affect the safety of workers, unless the plans and specifications have been submitted to and approved by the competent authority. The approval is a prerequisite for obtaining a Factory License and commencing manufacturing operations.
The plans must be prepared by a licensed architect or engineer registered with the Council of Architecture or the respective state body. They must cover every aspect of the factory premises - from the site layout and building construction to machinery placement, ventilation systems, fire escape routes, drainage, and sanitary facilities.
Key Aspects of Factory Plan Approval:
Statutory Requirement: Mandatory under Section 6 of the Factories Act, 1948 - no construction can begin without prior plan approval.
Health & Safety Compliance: Plans must comply with Sections 11-20 covering ventilation, lighting, sanitation, fire safety, and worker welfare.
NBC Standards: Factory buildings must meet structural, fire protection, and construction standards of the National Building Code.
Time-Bound Validity: Approval is valid for 2-3 years; construction must be completed within this period or an extension sought.
Did You Know?
Constructing a factory without approved plans can attract fines up to ₹2,00,000 for the first offence and up to ₹5,00,000 with imprisonment up to 2 years for continued violations under Sections 92-96 of the Factories Act. The Chief Inspector can also order demolition of unauthorised construction.
When is Factory Plan Approval Required?
Factory Plan Approval is required under Section 6 of the Factories Act, 1948 in the following situations. Understanding when approval is needed prevents costly legal complications and construction delays.
1. New Factory Construction
Any new building proposed to be used as a factory - where manufacturing processes will be carried on with 10+ workers (with power) or 20+ workers (without power) - requires plan approval before construction begins.
2. Extension of Existing Factory
Any addition or extension to the existing factory premises - including new wings, additional floors, annexe buildings, or expanded production areas - requires fresh plan approval from the Chief Inspector.
3. Installation of New Machinery
When new machinery or equipment is being installed that significantly changes the factory layout, affects worker safety, or requires structural modifications to the building, plan approval must be obtained.
4. Change in Manufacturing Process
If the manufacturing process changes in a way that affects worker safety, ventilation requirements, fire hazard levels, or necessitates structural alterations, a revised plan must be submitted for approval.
5. Factory Relocation
Shifting a factory to a new premises requires complete fresh plan approval for the new site, even if the manufacturing process and machinery remain the same. Plans must reflect the new location's specifics.
Important Note!
Even minor structural alterations that affect fire escape routes, ventilation systems, or machinery spacing may require amended plan approval. Always consult the Chief Inspector of Factories or a qualified factory compliance consultant before making any changes to your approved factory layout.
Types of Factory Plans Required:
A comprehensive set of plans must be prepared and submitted for Factory Plan Approval. Each plan addresses a specific aspect of compliance under the Factories Act, 1948 and the National Building Code. Here are the key types of factory plans:
Floor plans, elevations, cross-sections, dimensions, room heights, wall thicknesses, material specifications
Section 6, NBC Part 3 & 4
Machinery Layout Plan

Important Note!
All plans must be prepared by a licensed architect or engineer registered with the Council of Architecture. Plans must bear the signatures of both the architect and the factory occupier. Incomplete or non-compliant plans will be returned for revision, causing delays in the approval process.

Step-by-Step Process for Factory Plan Approval:
The Factory Plan Approval process involves careful preparation and submission to the Chief Inspector of Factories. At IncorpX, we assist with the entire process on your behalf. Here's the step-by-step procedure:
Step 1: Engage a Licensed Architect or Engineer
Appoint a licensed architect or structural engineer registered with the Council of Architecture or relevant state body. The architect conducts a site survey, assesses the proposed factory layout, and understands the manufacturing process to prepare compliant plans.
Step 2: Prepare Factory Plans as per Factories Act & NBC Standards
The architect prepares the complete set of factory plans including site plan (1:500 scale), building plan (1:100 scale), machinery layout plan, ventilation plan, fire escape plan, and drainage plan. All plans must comply with Sections 11-20 of the Factories Act and the National Building Code of India.
Step 3: Obtain Required NOCs and Certificates
Secure necessary clearances before submission: Consent to Establish (CTE) from State Pollution Control Board, Fire NOC from State Fire Service, structural stability certificate from a licensed structural engineer, and land use certificate confirming industrial zoning.
Step 4: Submit Plans to the Chief Inspector of Factories
Submit the complete set of factory plans along with all NOCs, certificates, ownership documents, and the prescribed application form to the Chief Inspector of Factories through the state's online portal or at the Factory Inspectorate office.
Step 5: Inspection and Modifications (If Required)
The Chief Inspector or designated Inspector reviews the plans for compliance with the Factories Act and NBC standards. If deficiencies are found, the Inspector requests modifications. Revise and resubmit the plans as directed within the prescribed timeframe.
Step 6: Receive Factory Plan Approval Certificate
Upon satisfactory review, the Chief Inspector issues the Factory Plan Approval certificate authorising construction or extension as per the approved plans. The approval is valid for 2-3 years depending on the state.
Step 7: Commence Construction & Apply for Factory License
Begin construction strictly as per the approved plans. After completion, apply for a Factory License to commence operations. Any deviations from approved plans require fresh approval or an amendment.

Frequently Asked Questions About Factory Plan Approval
Understanding Factory Plan Approval requirements can be complex due to varying state rules and technical compliance standards. We've compiled answers to the most frequently asked questions to help you understand the process better.
Whether you're constructing a new factory or extending an existing one, these FAQs cover everything you need to know about Factory Plan Approval under the Factories Act, 1948.
A Factory Plan Approval is a mandatory clearance required under Section 6 of the Factories Act, 1948 before any person can construct, extend, or take into use any building as a factory. The plans and specifications of the factory building must be submitted to the Chief Inspector of Factories or the State Factory Inspectorate for approval. Without this approval, any construction activity for factory purposes is illegal and attracts penalties under Sections 92-96 of the Factories Act.
Factory Building Plans are approved by the Chief Inspector of Factories or the State Directorate of Industrial Safety and Health (DISH) in the respective state. For example, in Maharashtra it is the DISH Maharashtra, in Karnataka the Directorate of Factories, Boilers, Industrial Safety & Health, and in Tamil Nadu the Directorate of Industrial Safety and Health (DIFE). The plans must comply with the Factories Act, 1948 and the fire safety requirements of the National Building Code (NBC).
Factory Plan Approval is required in the following situations:
Construction of a new factory building
Extension or alteration of an existing factory premises
Installation of new machinery that changes the layout
Change in manufacturing process affecting worker safety
Relocation of the factory to a new site
Under Section 6 of the Factories Act, no building shall be used as a factory unless the plans have been approved by the competent authority.
Factory Plan Approval is the first step - it sanctions the construction or extension plans of the factory building before any construction begins. A Factory License is obtained after the factory is constructed and ready for operation, authorising the occupier to employ workers and commence manufacturing. You cannot apply for a Factory License without first obtaining Factory Plan Approval. Both are governed by the Factories Act, 1948.
The following plans must be submitted:
Site Plan (1:500 scale) - Showing the factory location, boundaries, adjoining roads, and surrounding area
Building Plan (1:100 scale) - Floor plans, elevations, and cross-sections with dimensions
Machinery Layout Plan - Position, spacing, and specifications of all machines
Ventilation Plan - Natural and mechanical ventilation systems per Sections 13-14
Fire Escape Plan - Emergency exits, fire escapes, firefighting equipment layout
Drainage Plan - Waste water disposal, effluent treatment, drainage systems
Factory Building Plans must follow precise scale requirements: Site Plans must be drawn to a scale of 1:500, while Building Plans (floor plans, elevations, cross-sections) must be drawn to 1:100 scale. Machinery Layout Plans should typically be at 1:100 or 1:50 scale depending on complexity. All plans must be prepared by a licensed architect or engineer, printed on standard drawing sheets, and bear the signature of both the architect and the factory occupier.
Under Sections 13 and 14 of the Factories Act, 1948:
Ventilation: Every factory must have adequate ventilation by circulation of fresh air. Temperature must be maintained at comfortable levels, and mechanical ventilation is required where natural ventilation is insufficient.
Lighting: Sufficient and suitable natural and artificial lighting must be provided in every part of the factory where workers work or pass through. Windows must provide at least 1/6th of floor area for natural light.
Detailed ventilation calculations must be included in the submitted factory plans.
Factory Plans must incorporate fire safety as per the National Building Code (NBC) and Sections 38-40 of the Factories Act:
Minimum two means of escape from every floor
Fire-resistant construction materials for walls, floors, and staircases
Adequate width of staircases and corridors for emergency evacuation
Clear marking of emergency exits and escape routes
A Fire NOC from the State Fire Service is required along with the plan submission.
The typical processing time for Factory Plan Approval is 15 to 30 days from the date of complete submission. However, this varies by state: Maharashtra DISH typically processes in 15-21 days, Karnataka DLFE takes 21-30 days, Tamil Nadu DIFE processes in 15-25 days, and Gujarat DISH in 15-20 days. If modifications are required by the Inspector, additional time of 7-15 days may be needed for resubmission.
Government fees for Factory Plan Approval vary by state and the size of the factory. Fees typically range from ₹2,000 to ₹25,000 based on the factory area and number of workers. Additional costs include architect fees for plan preparation, structural engineer certification, and NOC charges. At IncorpX, our professional assistance charges start at ₹9,999 covering plan preparation coordination, documentation, submission, and follow-up with the Chief Inspector's office. Listed amounts are IncorpX professional charges for assistance. Government fees are charged separately at actuals.
Key documents include:
Site Plan at 1:500 scale with boundaries and surroundings
Building Plan at 1:100 scale with floor plans and elevations
Machinery Layout Plan with specifications
Ventilation and lighting calculations
Structural Stability Certificate from a licensed engineer
NOC from State Pollution Control Board
Fire NOC from Fire Service Department
Ownership documents or registered lease deed
Land use certificate (industrial zoning)
Environmental clearance (where applicable)
Occupier's declaration and undertaking
Architect's certificate with registration number
Constructing a factory without Plan Approval is a serious offence under the Factories Act, 1948. Under Sections 92-96, penalties include:
Fine up to ₹2,00,000 for the first offence
Fine up to ₹5,00,000 or imprisonment up to 2 years for repeated violations
The Chief Inspector may also issue a stop-work order halting all construction activity.
Factory Plan Approval is typically valid for 2 to 3 years from the date of issuance, depending on the state. Construction must commence and be completed within this period. If the construction is not completed within the validity period, the occupier must apply for an extension of approval before expiry. Any significant deviations from the approved plans require fresh approval or an amendment application to the Chief Inspector.
Yes, but any significant modification to the approved plans requires prior approval from the Chief Inspector of Factories. Minor modifications (cosmetic changes, non-structural alterations) may be acceptable with a notification, but major changes such as additional floors, changes in machinery layout, alterations to fire escape routes, or structural changes require a fresh plan submission or amendment application. Implementing unauthorised modifications can result in plan approval cancellation and penalties.
The Chief Inspector of Factories is the statutory authority appointed under Section 3 of the Factories Act, 1948. Their role in plan approval includes:
Reviewing submitted factory building plans for compliance
Ensuring plans meet health, safety, and welfare provisions (Sections 11-20)
Ordering modifications if plans are deficient
Granting or refusing approval within the prescribed timeframe
Conducting inspections to verify compliance with approved plans
Under Sections 15-19 of the Factories Act, 1948, factory plans must include:
Latrines and urinals: Separate for male and female workers, minimum 1 per 25 workers
Washing facilities: Adequate supply of clean water with soap and towels
Drinking water: Cool drinking water within 6 metres of every workplace
Spittoons: Sufficient number maintained in clean condition
First-aid rooms: Mandatory for factories with 500+ workers
The plan must clearly show the location, dimensions, and number of all sanitary facilities.
Yes, the National Building Code of India (NBC 2016) prescribes standards for factory building construction. Factory plans must comply with NBC requirements for structural safety, fire protection, electrical installations, plumbing, and ventilation. The NBC provisions supplement the Factories Act requirements and are particularly important for fire safety, means of egress, and structural design. The Chief Inspector typically cross-references NBC standards while reviewing factory building plans.
Yes, a Consent to Establish (CTE) from the State Pollution Control Board (SPCB) is typically required before or along with Factory Plan Approval. This applies especially to factories classified under Red or Orange categories by the Central Pollution Control Board (CPCB). The CTE ensures the proposed factory will comply with environmental norms for air emissions, water discharge, hazardous waste, and noise levels. Additionally, an Environmental Impact Assessment (EIA) may be required for large-scale industrial projects.
Yes, many states now offer online submission of Factory Plan Approval applications. Maharashtra accepts applications through the DISH portal, Karnataka through the Karnataka Udyog Mitra portal, Tamil Nadu through the single-window portal, and Gujarat through the Factory License portal. At IncorpX, we assist with the complete online submission process including document upload, fee payment, and follow-up with the Inspector's office.

Highly recommend IncorpX to anyone starting a business!
