There Law No. 2025-1129 of November 26, 2025<\/a> The simplification of urban planning and housing law pursues the legislator's objective of accelerating the processing of urban planning permit disputes and the completion of construction projects.<\/p>\n It considerably restricts the possibilities for third parties, mainly neighbors of construction projects, to challenge construction operations.<\/p>\n This reform of urban planning law litigation concerns any decision relating to a planning permission<\/strong>. Thus, the modification of the appeals regime concerns both decisions likely to harm third parties, namely building, development or demolition permits and decisions of no opposition to a prior declaration of works, but also decisions which harm petitioners, that is to say decisions to withdraw an authorization and decisions to refuse an application for authorization.<\/p>\n<\/p>\n This reform establishes a special regime<\/span> of the common law of administrative litigation of the two-month appeal period and of the extension of the period of legal appeal in the event of an informal appeal.<\/p>\n New article L. 600-12-2 of the town planning code:<\/p>\n<\/p>\n The deadline for lodging an informal appeal or a hierarchical appeal against a decision relating to a planning permission is one month. The time limit for an informal appeal by the petitioner and the injured third party is reduced to one month<\/span> instead of two. <\/strong><\/p>\n This period is extremely short, given that the administration also has a period of one month to communicate the documents of a building permit to a person who requests them.<\/p>\n An informal appeal no longer suspends the time limit for legal proceedings.<\/strong>.<\/p>\n The amicable approach no longer has any impact on the time limit for bringing the matter before the administrative judge.<\/p>\n The time limit for legal appeals is therefore two months<\/strong> from the date of regular posting of the granted planning permission<\/u> Or from the date of notification in the event of refusal or objection to the construction project<\/u>, It does not matter whether an informal appeal has been filed<\/u>.<\/p>\n The informal appeal loses its main purpose<\/strong> : that of negotiating with the petitioner and\/or the administration.<\/p>\n Local authorities will likely see an increase in the number of legal challenges against their decisions and will therefore have to consider whether to withdraw or issue an amended authorization.<\/p>\n<\/p>\n Restriction of pattern substitution over time<\/strong><\/span><\/p>\n The reform now requires the administration to detail all the reasons for refusal in the a period of two months from the date of filing a legal appeal<\/span> against a refusal of planning permission.<\/p>\n Pattern substitution is now limited in time.<\/p>\n Paragraph 2 of the new Article L. 600-2 of the Town Planning Code<\/a> :<\/p>\n<\/p>\n When the administrative judge is seized of an appeal for annulment against a decision governed by this code and refusing the occupation or use of the land or of a request for the annulment or reformation of a judicial decision concerning this decision, the author of the latter may no longer invoke new grounds for refusal after the expiry of a period of two months from the registration of the appeal or the request. <\/p><\/blockquote>\n Presumption of emergency<\/strong><\/span><\/p>\n Since the ELAN law, the urgency is presumed to be met for applications for interim suspension (Article L. 521-1 of the Code of Administrative Justice<\/a>) directed against building permits: decision of no objection to prior declaration, building permit, development or demolition permit (Article L. 600-3 of the Town Planning Code<\/a>).<\/p>\nNeutralizing the appeal process <\/h2>\n
\nThe silence maintained by the administration for more than two months regarding this appeal to the competent authority constitutes a rejection decision.
\nThe time limit for bringing legal proceedings against a decision mentioned in the first paragraph is not extended by the exercise of an informal appeal or a hierarchical appeal.\n<\/p><\/blockquote>\n<\/h2>\n
