If you need assistance or have questions about filling out the application, we encourage you to schedule a pre-application meeting with the Act 250 District Coordinator, who will discuss your project with you and provide guidance on filling out the required forms. If you feel you need more substantial support, you are welcome to hire a private Act 250 consultant.

General Act 250 Application Submission Guidelines

Act 250 Application Guide

See the Act 250 Application Guide for specific instructions on application submission, which is particularly helpful for first-time applicants and also includes contact information for our organization and other state agencies. In general, applicants must submit 1 electronic application and all accompanying electronic documents (including any site plans), 1 complete set of paper site plans, and the fee check to the designated District Office  (applicants of District 2 may forego submitting the set of paper site plans—the electronic version will suffice). The electronic files populate the Act 250 Database, which facilitates applicants', state agency staff's, and the general public's access to Act 250 documents. The paper set of site plans will be primarily used for quick reference at the District Office or as a backup during hearings.

The Additional Resources page contains other useful information for applicants.

Act 250 Application Form, Schedule G, Exhibit List, and Statutory Party List(s)

The Act 250 Application Form and Schedule G are PDF-fillable forms. The application form automatically adjusts its questions and the information required based on your responses in the application and the nature of the project. Schedule G is now a separate form to ease applicant submission to the Statutory Parties. Schedule G must be saved to your computer and then completed and submitted via e-mail, as instructed in the Act 250 Application Guide, to the Statutory Parties associated with your project. You will also need to download the Exhibit List form to your computer, complete it, and submit it with your electronic application as instructed in the Act 250 Application Guide.

Certification of Actual Construction Costs

Certification of Actual Construction Costs form must be filed within 1 month after construction has been substantially completed or 2 years from the date of the permit, whichever occurs first.

Tips for Working with the Act 250 Application Forms

The Act 250 Application Form is a PDF-fillable form (i.e., a "smart-form") that has replaced the original Regular (Long Form), Short Form, Extension of Construction Completion Date, and Administrative Amendment Forms. You will need to download and save the form to your computer for completion and submission to the designated District Office. The PDF form meets the requirements for the electronic copy of the application required according to our electronic submission guidelines (instructions are contained in the Act 250 Application Guide).

"Please wait" error:

Some users experience a "Please wait" error when they click on the link to open the form. This error occurs because some web browsers do not support PDF.

To avoid the "Please wait" error, follow these steps: 

  • In order to fill out the application form (and most of our other online forms), you will need a PDF-reading program. If you do not have one, our forms are compatible with Adobe Reader, which is free to download and use. If you have Adobe Reader already installed, verify that you are using version 9 or higher for best results.
  • Once you have installed Adobe Reader, return to and click on the application form link. This action will bring you to the application form page (screenshot below).
  • On the application form page, use your cursor to hover over the PDF file name, then right click with your mouse. In the drop-down menu that opens (screenshot below), choose "Save target as..." (or "Save link as...", "Save linked file as...", etc; variations depend on your browser) and then save the file to your desktop.
  • To successfully open the file, first open your PDF reading software (eg, Adobe Reader), then use the program to find the application PDF file on your desktop; then click "Open." If you skip this step and double-click on the PDF file on your desktop, you will continue to receive the "Please Wait..." error (because your computer will try to use your web browser and not Adobe Reader to open the file). 
  • If you are still having trouble, contact your Act 250 district office for assistance. 

Save target as a PDF to download to your desktop rather than double-clicking to open and download the file.

Save our form files to your computer first and save often!

  • To avoid losing information you enter into the application form, be sure to save all forms to your computer before you start filling them in. Once saved to your computer, be sure to save often while you work through the form.
