What Is the Purpose of a Building Permit?

The purpose of a permit for any building project is to ensure that the changes you make to your home are compliant with The International Building Codes (IBC)  and any local zoning and construction regulations.

Regulations ensure that all remodeling and construction work is safe. They protect you, the homeowner, against any unnecessary damage at a later date and protects your investment and safety.

During your remodeling project, a city/county official will inspect the work done at regular intervals to ensure that you’re following all regulations. The official will sign off the work once the job is complete, giving you peace of mind that your remodeling job is completed correctly.

Each state has different requirements depending on the local conditions, so always check with your local zoning office before planning your project.

While local building regulations differ between states, if you’re remodeling your bathroom, you will generally need a permit if you make structural or plumbing changes.

The permits required will be specific to your local city or county and must comply with local land use laws and the IBC.

To be on the safe side, contact your local zoning office to find out the requirements before you begin.

If you use a contractor to remodel your bathroom, ensure that they apply for and have received a valid permit before starting the renovation. As a DIYer, you can apply for permits, but this can be a lengthy and costly process.

So your best bet is probably to use a registered contractor who is familiar with the local building regulations and who is familiar with the permit process in your local area. As the homeowner, it’s your responsibility to ensure that the proper permits are in place.

What are the Different Permit Types for Remodeling your Bathroom?

If you’re completely renovating your bathroom and moving fixtures, then you would need a permit to tile your bathroom.

This is because the placement of new tiles can impact the existing plumbing and electrical wiring conduits and have an effect on waterproofing.

However, if you’re simply changing broken tiles or replacing a section without impacting the plumbing and wiring, go ahead.

Do You Need a Permit to Replace a Bathroom Vanity?

The easiest changes when upgrading your bathroom are replacing an existing sink and faucet. Often these are a quick swap and don’t involve permits, as there are no changes to the plumbing.

The same applies to vanities and countertops – no permits are required if you are simply replacing them.

A permit would apply if you restructure the bathroom layout and move fittings and fixtures from the original locations to a new one.

When Don’t I Need a Permit When Remodeling My Bathroom?

Typically, you won’t need a permit for minor alterations. Always check your local laws before you begin. Regulations do differ from state to state, city to city, and county to county.

A permit is not a requirement for the following improvements to your bathroom:

  • Painting, drywall, or wallpaper in the bathroom. A permit is not required as long as plumbing, electrical, and structure rules are observed.
  • Replacing existing fixtures, finishes, and appliances. No permit is necessary if you exchange an existing bathtub, sink, toilet, flooring, or light fitting, without changing the plumbing or electrical wiring.
  • Vanities and countertops. Swapping out your existing vanity or countertop, or extending the existing tops does not require a permit as long as plumbing and electrical rules are followed.

How To Apply for a Bathroom Remodeling Permit

The best way to apply for a bathroom remodeling permit is to find a good contractor familiar with all the local rules and regulations.

He will file all the forms, plans, and required documentation and follow up with the authorities. Be prepared for a long wait, though – some applications could take 2 – 6 months before they are approved.

As the homeowner, you are responsible for the correct permits, so always ensure that they are right.

What Happens IF I Don’t Get a Permit for Remodeling My Bathroom?

Some homeowners don’t bother following the permit rules when remodeling their bathrooms. If a contractor that you hired for the job advises that you don’t need a permit for a remodeling job, consider hiring a new contractor.

Not obtaining the correct permits can have severe consequences if you are caught:

  • The authorities could insist that you tear down the completed work, apply for the permits, and start again. A costly option.
  • The authorities could force you to obtain a permit and charge more (double or triple) the permitting fees.
  • Selling your home could be a problem if it comes to light that the bathroom was remodeled without the proper permits. This could lower the value of your home, and you might have to apply for outstanding permits to bring the bathroom up to code.
  • Some insurance companies won’t pay for damages to a home if the correct permits are not produced after a damages claim.
