Declaración responsable ambiental (environmental responsible declaration) of the activity before your Autonomous Community

Declaración responsable ambiental (environmental responsible declaration) of the activity before your Autonomous Community is filed with Órgano ambiental de su comunidad autónoma y ayuntamiento del emplazamiento. With Managora you do it 100% online: you answer a few questions, sign a digital mandato (power of representation) and we draft, sign and file your application for you. Estimated total cost: €182. Official tasa (government fee): The declaración responsable ambiental itself does not usually incur an autonomous community tasa (official fee), but there are two costs that do, and we tell you about them upfront. One: the environmental technical report or project must be signed by a competent technician and costs from 300 to 1.500 euros depending on the activity and surface area; you can provide it yourself if you already have it, or we can arrange it for you. Two: the opening tasa of the Ayuntamiento, which is set by its tax ordinance and ranges from a few dozen to several hundred euros, and in some municipalities is a percentage of the IAE rate for the activity. We confirm both exact figures for your municipality before you pay anything.

Before opening, there are two different filters and almost no one knows there are two: the municipal one and the AMBIENTAL (environmental) one, which belongs to your Autonomous Community. Each community has a law that classifies each activity by its CNAE code and decides whether it requires an environmental authorisation, an environmental verification, or a declaración responsable ambiental, which is the route for lower-impact activities. We check which category yours falls into, tell you if this route or a heavier one applies to you, and draft and submit the declaration with its annex. This must be done BEFORE the municipal licence: without the environmental step resolved, the Ayuntamiento will not let you open.

What we charge you: €182
Managora's fee: €182.00 (21% VAT incl.)

Processing time: The declaración responsable allows you to start the activity from the moment it is submitted, with subsequent verification by the administration. If, when checking your CNAE, it turns out that your activity does NOT go through this route but through an environmental verification or authorisation, we will tell you before charging you: those go through a different procedure and take months, not days.

Prerequisites we also handle for you

This procedure needs documents that we also obtain. If you are missing any, ask us for it here and come back once you have it:

Poder notarial (notarial power of attorney: general, special or preventive)€50

And whatever a third party provides, we arrange it

Project or certificate signed by an architect or engineer

You do not have to look for anyone: we coordinate it. As it is provided by a third party it is quoted separately and does not go inside the price of this procedure, and we tell you the amount before ordering it.

Legal basis and things to bear in mind

FIRST THE ENVIRONMENTAL, THEN THE MUNICIPAL. The environmental procedure is prior to the declaración responsable or the licence from the Ayuntamiento, and until it is resolved, the necessary licences for the operation of the activity cannot be granted.
THE CLASSIFICATION IS NOT OPEN TO DEBATE: each regional law has an annex that states, by CNAE code and threshold, whether the activity requires an integrated environmental authorisation, an impact assessment, an environmental verification, or a declaración responsable ambiental. What we do here is read that annex, not estimate.
IT IS SIGNED BY A TECHNICIAN IN ADDITION TO THE HOLDER. The declaración responsable ambiental is not a form that the interested party fills out alone: the technical annex is signed by a competent technician. That cost is separate and is stated upfront.
IF THE PROPERTY IS A DWELLING, the order changes: first of all, you must request the certificate of urban compatibility, because planning regulations usually reserve residential use and relegate annoying activities to industrial or rustic land. Spending money on the technical report before having that certificate is a waste of money.
CANTABRIA, current framework: Ley de Cantabria 9/2026, of 23 July, on Environmental Control, in force since 29-08-2026, which REPEALS Ley 17/2006 on Integrated Environmental Control. Its Annex I classifies activities by CNAE. Verified example: A0149 "other livestock farms", which is where pet breeding falls, appears as a declaración responsable ambiental WITHOUT A THRESHOLD, meaning regardless of the number of animals.
FRAMEWORK BY COMMUNITY (IDs and validity verified against the consolidated BOE on 2026-08-23). Andalucía: Ley 2/2026 for Environmental Management, which repeals 7/2007 GICA, with environmental qualification in the hands of the Ayuntamiento. Aragón: Ley 11/2014 (environmental licence for classified activities). Asturias: Ley 1/2023 on Environmental Quality. Baleares: Ley 7/2013 on activities and DLeg 1/2020 on environmental assessment. Canarias: Ley 7/2011 on classified activities. Cantabria: Ley 9/2026. Castilla-La Mancha: Ley 2/2020. Castilla y León: DLeg 1/2015, recast text on Environmental Prevention. Cataluña: Ley 20/2009. Comunitat Valenciana: Ley 6/2014. Extremadura: Ley 16/2015. Galicia: Ley 9/2013, which abolished the municipal activity licence and replaced it with a prior communication. La Rioja: Ley 6/2017. Madrid: Ley 2/2002, whose environmental assessment report for activities is prior and BINDING for the municipal licence. Murcia: Ley 4/2009. Navarra: Ley Foral 17/2020, with the classified activity licence in Annex 3. País Vasco: Ley 10/2021 on Environmental Administration of Euskadi.
THE NAMES CHANGE, THE FILTER DOES NOT. What in Cantabria and the Comunitat Valenciana is called a declaración responsable ambiental, in Andalucía is calificación ambiental, in Extremadura comunicación ambiental, in Aragón, Canarias, Navarra, and País Vasco licence or communication of classified activity, and in Galicia comunicación previa. It is the same procedure and is covered by this file.
State support framework: Ley 21/2013 on environmental assessment, RDLeg 1/2016 on integrated pollution prevention and control, Ley 34/2007 on air quality, Ley 37/2003 on Noise, and art. 84 bis of Ley 7/1985 (LBRL).
Natural connections: certificado_compatibilidad_urbanistica (goes before), licencia_apertura_local_actividad and declaracion_responsable_apertura_local (go after), alta_autonomo and modelo_036.
