How To Get a Basement Renovation Permit?

Having a basement permit helps you navigate through the project efficiently, and your contractor will usually file for it on your behalf. This is how the process looks:

  1. You or your contractor need to contact the local building department to check regulations and building codes because each area has its requirements.
  2. Prepare detailed plans and drawings for your proposed renovation. Those plans can include a site plan, floor plan, and elevation plan.
  3. Fill out the application form from your building department, and be prepared to pay a permit fee. Building permit cost varies by location and it can impact your overall budget for the project.
  4. Once you pass all the inspections and get the permit, you can start your basement renovation.

By following these 4 steps, you will make sure you respect the local regulations, and that your basement project will be done properly.

Let’s see if there is a chance to obtain a building permit retroactively.

Can You Get a Retroactive Building Permit?

A retroactive permit allows homeowners to bring unpermitted basements up to code

In some areas, there’s a possibility of getting a permit for a basement that was previously done without having one, and this type of permit is called retroactive. Obtaining a retroactive permit requires completing the form for a permit, and getting the inspector to sign it, after checking the safety and legality of your finished basement. 

If the inspector decides that any of the work was not done according to the building code regulations of the area, you will need to fix all of the issues to get a retroactive permit. This includes redoing some of the work, which will cost extra money. You can spend thousands of dollars to bring your basement up to code retroactively until your contractor makes sure the basement is done properly, respecting the building codes.

It’s important to know that this type of permit is not allowed in all areas. Some building departments can demand that you return the space to its original condition and remove all the illegal additions.  

Although in some areas it’s possible to get a retroactive permit, putting it all together, it’s much better to obtain a permit before the beginning of the process, but let’s see what happens if you by any chance, decide to finish your basement without obtaining a permit at all.

Resale Complications

Without the permits, potential buyers won’t be able to secure a mortgage, which can limit the number of interested buyers and lower your home’s resale value.

Violations and Associated Fees

You can get financial penalties along with inspection fees. This can make your renovation process more complicated and will cost you lots of money. 

Insurance Coverage Issues

In case of damage insurance company can deny coverage and refuse to pay out claims because renovations don’t meet the necessary policy requirements. You will have to pay for all repairs and losses, which can have a huge impact on your finances.
