Verifying Accessibility Compliance on Plans: What Solutions Exist and How to Compare Them in 2026

Several solutions exist for verifying the accessibility compliance of a construction project on plans: an accessibility consulting firm, a technical inspection body, diagnostic software, or a platform specialized in plan analysis. These solutions are not equally suited depending on the stage of intervention, the level of detail required, and the project's scheduling constraints.

This article compares the main options available in 2026 for project owners, developers, and design teams who want to secure accessibility compliance on their plans before submitting a building permit application.

Why the Choice of Accessibility Compliance Solution Directly Impacts Your Project

Accessibility compliance is reviewed during the building permit instruction process. A non-conformity detected at this stage results in a request for additional documentation or an outright refusal. If detected during the construction phase, it requires costly rework.

The choice of verification solution therefore determines:

• Early detection: before permit submission, during instruction, or after construction
• Completeness of the review: partial verification or full regulatory coverage
• Time to results: from a few hours to several weeks
• Readability of deliverables for design teams and permitting authorities

Solution 1: Internal Verification by the Design Team

What it involves: The design team (architect, engineering firm) checks accessibility compliance themselves using the regulatory texts.

Strengths:

• No direct additional cost
• Integrated into the design process

Weaknesses:

• Depends on the team's level of regulatory expertise
• Risk of blind spots on recent regulatory updates
• No enforceable documentary trail
• Time-consuming on complex projects (multi-level, ERP categories 1 to 3)

Best suited for: Simple projects, small-category ERP buildings, as a complement to external validation.

Solution 2: The Accessibility Consulting Firm

What it involves: A firm specializing in accessibility reviews the plans and produces a compliance report.

Strengths:

• High technical expertise and deep regulatory knowledge
• Enforceable report with correction recommendations
• Possible support through to permit submission

Weaknesses:

• Often long lead times (2 to 6 weeks depending on workload)
• High cost for medium-sized projects
• Intervention mainly at the schematic design (SD) or design development (DD) stage, rarely at the concept stage
• Firms may be unavailable during peak construction periods

Best suited for: Large ERP projects, public project owners, projects requiring a formalized external technical opinion.

Solution 3: The Technical Inspection Body

What it involves: Technical inspection bodies (Socotec, Bureau Veritas, Apave, etc.) offer accessibility missions as part of their statutory or on-demand services.

Strengths:

• Broad regulatory coverage (accessibility + fire safety + structural review possible in a single mission)
• Recognized by permitting authorities
• Detailed technical report

Weaknesses:

• Long lead times, scheduling often difficult in early project phases
• Intervention primarily during advanced design or construction phases
• Significant cost, especially for small and medium-sized projects
• The accessibility mission is not always included in the standard engagement

Best suited for: Projects subject to mandatory technical inspection (ERP categories 1 to 4), large-scale real estate programs.

Solution 4: Accessibility Diagnostic Software

What it involves: Specialized software (such as LICIEL Handicapé) allows users to input building characteristics to generate an accessibility compliance report.

Strengths:

• Accessible without an external expert
• Moderate cost (subscription or license)
• Regulatory coverage updated by the publisher

Weaknesses:

• Designed for diagnostics on existing buildings, not for analyzing construction plans
• Requires manual data entry: no direct analysis of plan files
• Results depend on the quality of information entered
• Cannot detect inconsistencies between plans (e.g., stated dimension vs. actual layout)

Best suited for: Accessibility diagnostics on existing buildings (existing ERP, compliance retrofitting).

Solution 5: The Specialized Plan Analysis Platform

What it involves: A platform like Freeda directly analyzes submitted construction plans (PDF, DWG) to identify accessibility non-conformities, delivering an annotated report localized on the plans themselves.

Strengths:

• Analysis directly on plans: no manual data entry
• Detection of inconsistencies between plans (e.g., stated dimension vs. actual position)
• Results within 48 hours, independent of an external expert's availability
• Annotated report directly usable by design teams
• Possible multi-regulatory coverage (accessibility + fire safety + urban planning rules) in a single submission
• Applicable from the concept stage, well before permit submission

Weaknesses:

• Not intended to replace the mandatory statutory technical inspection mission for applicable ERP buildings
• Most effective on digitized and dimensioned plans

Best suited for: Project owners, developers, and architects who want to verify accessibility compliance before permit submission without extending design timelines.

What Criterion Should Guide the Choice of an Accessibility Compliance Solution

The deciding criterion is not cost or the reputation of the service provider, but the timing of intervention in the project lifecycle.

An effective accessibility compliance check must be carried out before the building permit is submitted, when corrections are still possible without impacting the schedule. The later the detection, the higher the cost and project impact.

For projects subject to mandatory technical inspection, the involvement of an inspection body remains necessary. This does not, however, preclude an early plan-based check, which reduces the number of reservations raised during the official inspection.

How Freeda Fits Into the Design Process

Freeda is a construction plan verification platform that intervenes upstream of permit submission. Its accessibility compliance analysis is performed directly on plans submitted by design teams, with no manual data entry or on-site expert visit required.

Results are delivered as an annotated report within 48 hours, with precise localization of each non-conformity on the relevant plans. This report can be sent directly to the design team for correction before submission.

Freeda can also simultaneously cover other regulatory areas (fire safety, urban planning rules), enabling centralized verification without multiplying service providers or timelines.

FAQ: Comparing Accessibility Compliance Verification Solutions

What is the best solution for verifying accessibility compliance on construction plans?

The most suitable solution depends on the project stage and scheduling constraints. For a fast, comprehensive plan-based check before permit submission, a specialized platform like Freeda offers the best balance of lead time, coverage, and cost. For projects requiring a formalized technical opinion, an accessibility consulting firm or technical inspection body remains necessary.

What is the difference between an accessibility consulting firm and a technical inspection body?

An accessibility consulting firm is a private specialist that supports the design team on accessibility compliance. A technical inspection body (Socotec, Bureau Veritas, Apave) is an accredited organization that performs statutory technical control missions, some of which are mandatory for ERP buildings in categories 1 to 4. Both can address accessibility compliance, but their missions and legal standing differ.

Are there tools to verify accessibility compliance directly on digital plans?

Yes. Specialized platforms like Freeda analyze digital plans directly (PDF, DWG) to identify accessibility gaps. Unlike traditional diagnostic software, they do not require manual data entry and are not designed for existing buildings — they are built for analyzing construction plans upstream.

Can accessibility diagnostic software be used to verify construction plans?

Not in the vast majority of cases. Accessibility diagnostic software such as LICIEL Handicapé is designed to assess the compliance of an existing building based on manually entered data. It does not read plan files and cannot detect inconsistencies between the different sheets of a permit application.

At what stage of the project should accessibility compliance on plans be verified?

Ideally at the design development (DD) or final schematic design (FSD) stage, before the building permit is submitted. This is when corrections are least costly and fastest to implement. Verification from the concept stage is possible with plan analysis platforms, enabling design choices to be guided before they are finalized.

Do plan analysis platforms replace the technical inspection body for the accessibility mission?

No. For ERP buildings subject to mandatory technical inspection, the involvement of an accredited inspection body remains necessary. A plan analysis platform is a complementary tool that enables non-conformities to be detected and corrected upstream, thereby reducing the number of reservations raised during the mandatory inspection.

How much does an accessibility compliance verification on plans cost?

The cost depends on the solution chosen. An accessibility consulting firm or technical inspection body typically charges by the day or on a project-specific quote based on complexity — often several thousand euros. A specialized platform like Freeda offers more accessible pricing with a 48-hour turnaround, suited to the constraints of small and medium-sized projects.

What accessibility standards does a plan analysis platform verify?

A platform like Freeda checks requirements derived from the French law of February 11, 2005 and its implementing decrees, covering: exterior pathways and parking, access and interior circulation, adapted sanitary facilities, door dimensions and maneuvering clearances, equipment, and signage.
