Do you need a permit to build an outbuilding?

Constructing an outbuilding can be a great way to add value to your home and effectively use the space in your property. But, before you get carried away, you must make sure you do things by the book.

You might well need a permit before you can put up an outbuilding. This isn’t the case for every outbuilding project – but it’s best to assume that you might need one and check with your local authority so that you know you’re following the rules for your construction and your location.

Here are a few things to consider when it comes to outbuilding permits.

Which buildings require a permit?

Permission will depend on several key factors. These include:

• size of the building
• where you’re putting the building
• specific rules and regulations in your state and county
• purpose of the building
• environmental impact

In general – the bigger the project, the grander your ambitions and the more expensive it is to make, the more likely it is to need a permit. For example, putting up a small shed, greenhouse, or playhouse will generally not require a license.

As a rule of thumb, anything under eight feet tall and less than 160 square feet in area should be delicate. Again, use this as a rough guide and double-check the specific rules.

Buildings providing somewhere for guests to sleep will likely be more significant. It’s also becoming more popular to create outbuildings as small affordable housing – but these dwellings have their own set of rules attached and should be treated differently.

How to get a permit

If you hire a contractor to carry out the work on your building project, they will often include the price of the permit when negotiating your deal. Always double-check that they have included the price and are requesting it themselves if this is the case.

If you’re building the structure yourself, you can start by calling your local building authority. They will want to see a project description and will issue you with an application form (or forms) for your needs. This will cover the construction details – including plumbing and electricals if necessary.

You will need to submit this paperwork to your licensing office – along with any necessary fees. Once complete, they will issue a permit certificate, which you can display in a prominent place close to where the work is being carried out.

Some structures may need to pass specific regulations, so read up on construction rules for your area or more general engineering standards – like this guide for metal buildings. Suppose you need your structure to adhere to building codes. In that case, you can also request inspections in some regions to ensure the local authorities are happy with the quality of the work and can give feedback on anything they might consider to be ‘not up to code’ yet.

Can I ignore getting a permit?

You really should not ignore the need for a permit. While waiting for permission can be a lengthy process, it’s a necessary step towards getting your outbuilding constructed. (It’s also better to double-check and ensure you don’t need one for a modest structure.)

Remember, the risks of not getting a permit are far more significant:

• the ticket will cost you more money to get a sign-off post-build – if you are allowed to
• If a local authority finds out, they can also require you to remove the building, rendering your project useless.
• If there is an incident – such as a fire or a plumbing disaster requiring an insurance claim – then acting without a permit may mean your insurance will not cover you. Any damage or liability policies will be void.
• Suppose you try to sell your home or property with an outbuilding, and it is discovered in the buyer’s inspection that you did not have a permit. In that case, you can be prevented from selling and asked to start the work again with the proper licenses to ensure the structure is up to code.

So, don’t neglect the permit stage for your next outbuilding project. Check if you need one for your build. Size matters – more footprint, and the likely answer is yes – you will need a permit.

Start your process by knowing and abiding by the rules in your area; now, you know the risks should you choose to ignore the rules.
