Procedure for Building Permit Applications

  1. Please fill out the Building Permit Application form and Schedule 1- Designer Information and email your application, along with the drawings, details, and Site Plan to jrussell@mississippimills.ca. A list of all required documents for building permit applications can be found on the Building Permit Information page. 

    If you are applying for a building permit and you are not the owner, you will need to submit a Letter of Authorization Form signed by the owner.
    • Please note, if you wish to cancel your permit application after you've submitted it, there will be costs that cannot be refunded. Schedule B of the Building By-law lists the Refund Percentages available.
  2. Once we receive your application, the information will be entered into our CGIS software program and assigned an application number for tracking. 

  3. Your application and site plan will first go to the Planning Department for their Zoning By-law review and comment. They will contact you directly if they require additional information or documentation.

  4. Once approved by the Planning Department, a Building Inspector or 3rd party reviewer, RSM Building Consultants, will review your application and drawings. Your residential application should be reviewed and approved in 10 business days IF you have provided a complete package and IF there is no additional information required to review your application. If additional information is required, you can expect delays.

  5. Once your application is reviewed by the Building Department, the Chief Building Official (CBO) does the final approval, assigns a permit number, and enters the associated fees and inspections.

  6. You will receive an email entitled "Invoice Building Permit..." with your building permit invoice when your Building permit has been reviewed and approved. Your permit fee can be paid by cash, cheque, or debit (please make an appointment if you would like to visit the Municipal Office located at 3131 Old Perth Rd, Almonte, to pay your fee). 
    **Your building permit is NOT valid until your invoice has been paid in full.

  7. Once we receive payment, we will email your Building Permit, receipt, and approved drawings.

  8. Please place the Building Permit in a conspicuous location on your property facing the road.

  9. Inspections are listed on your Building Permit. Please email jrussell@mississippimills.ca or call 613-256-2064 ext. 260 to book your inspections.

  10. Additional inspection fees may be assessed if an inspection is conducted and the work is either not ready, there is no access, insufficient documents are available, or if the number of inspections exceeds what is otherwise reasonable.

  11. All building permits have a set expiry date, after which a renewal of the permit will be required. Renewal fees are due annually upon expiry of the permit if the permit file is not complete. Please note the expiry date on your permit and contact the Building Department if your permit requires a renewal. Renewal fees can be found in the 2022 Building Fees and Charges By-law.

  12. Please note that if you wish to cancel your permit once the permit application process has begun, there will be costs that cannot be refunded. Schedule B of the Building By-law lists the Refund Percentages available.

Adding a Second Unit in an Existing Home

Adding a second unit is a great way to provide independent living for a family member or make a little extra money to help pay off the mortgage. But there are things you need to consider as you decide whether to build a second unit.  Is your home detached, semi-detached or a rowhouse that is more than five years old? Are you considering renovating it to add a second unit? If the answers are yes, then this guide can help you.  Before deciding to add a second unit, it is important that you first speak with your local municipal planning and building departments. They can tell you whether you are allowed to add a second unit on your property and answer any questions that you have related to local zoning, the Building Code and other by-laws. Please visit the Ontario Add a Second Unit to Your House website.
