Responsible Builders focuses on a single area the regulatory, technical, and practical information that building professionals must master to remain compliant. Each page of the site addresses a specific angle, from RE2020 to post-reception guarantees, including construction waste management. Effectively navigating this architecture requires understanding how the content is interconnected.
RE2020 and permit application date: the calendar trap that every page must reflect
Since May 1, 2026, RE2020 applies to new categories of buildings: hotels, shops, restaurants, sports facilities, industrial or artisanal buildings. The pages of Responsible Builders dedicated to energy compliance incorporate this extension, making them relevant far beyond just residential housing.
The technical point not to miss: the permit application date determines the applicable version of RE2020. Since July 1, 2026, the requirements modified by decree apply to applications submitted from that date. Two identical projects may therefore fall under different rules depending on their administrative timeline.
The pages of the site that deal with administrative procedures and IC-construction or IC-energy indicators gain value because they clearly distinguish the thresholds applicable before and after this pivotal date. It is by browsing the list of Responsible Builders pages that one can identify the updated content reflecting this regulatory change.
Builder guarantees and ten-year insurance: the pages to consult as a priority
The three post-reception guarantees (perfect completion, biennial, ten-year) form the legal basis of the relationship between builder and project owner. On Responsible Builders, these guarantees are the subject of distinct pages rather than a catch-all article, allowing direct access to the regime concerning a specific dispute or inspection.
Ten-year insurance remains the most frequent control point during a compliance audit. It covers damages compromising the solidity of the work or rendering it unfit for its intended purpose. The dedicated pages on the site detail the subscription conditions, common exclusions, and the consequences of a lack of insurance.
Distinguishing perfect completion guarantee and biennial guarantee
The perfect completion guarantee lasts for one year after reception. It covers all defects reported by the project owner, regardless of their nature. The biennial guarantee, on the other hand, covers separable equipment elements (shutters, radiators, plumbing) for two years.
The pages of Responsible Builders separate these two regimes to avoid the frequent confusion between what falls under perfect completion and what falls within the biennial scope. A builder receiving a claim thirteen months after reception knows immediately which page to turn to.
- Ten-year guarantee page: conditions for activation, prescription periods, mandatory insurance certificate before starting work
- Biennial guarantee page: indicative list of separable equipment, case law on the boundary with the ten-year guarantee
- Perfect completion page: reserve procedure at reception, formalities of the minutes, deadline for lifting reserves
REP PMCB and construction waste management: a still evolving framework
The REP PMCB (extended producer responsibility for construction products and materials) sector was set to undergo a thorough overhaul. Reform projects were revised after review by the Council of State, and no reform text was published by autumn 2026. Builders must therefore continue to refer to the existing framework.
Responsible Builders dedicates specific pages to sorting obligations, collection points, and approved eco-organisms. This content is useful because it prevents professionals from anticipating measures announced but not yet in force, a reflex that can lead to non-compliance due to excess or deficiency.
Why monitor updates to these pages
The operational difficulties of REP PMCB (insufficient territorial coverage of collection points, lack of data on actual flows) mean that the regulatory framework can evolve quickly as soon as a new decree is published. The pages of the site that follow this news allow checking in a few minutes if obligations have changed before launching a project.
Sitemap architecture: how to leverage the site structure
The sitemap of Responsible Builders organizes content by regulatory obligation, not by building type. This editorial choice facilitates navigation for a professional faced with a specific legal or technical question.
We recommend starting from the sitemap to identify the page corresponding to the relevant obligation, then checking the date of the last update displayed on the page. Regulations evolve by decree, and a page not updated for several months may no longer reflect the applicable law.
- RE2020 pages: IC-construction thresholds, IC-energy, categories of buildings concerned according to the permit application date
- Guarantee pages: post-reception liability regimes, durations, conditions for activation
- Waste and REP PMCB pages: sorting obligations, eco-organisms, collection points, status of the ongoing reform
- Administrative compliance pages: certificates, mandatory diagnostics, documents to provide for the building permit
The value of such an inventory lies in its ability to serve as a regulatory checklist before starting a project. Rather than multiplying searches across scattered sources, the professional has a single entry point, structured by obligation rather than by trade. This logic corresponds to how compliance checks are actually conducted on the ground.
