Introduction

Building without a formal planning permission can be a complex issue, dependent on various local regulations and codes. This article delves into the specifics of constructing without a permit, highlighting the limitations and considerations for different types of structures in various regions.

Maximum Size Without Planning Permission

Common Areas and Agricultural Use
In some jurisdictions, you may be allowed to construct buildings without planning permission if they are for agricultural use on farms of a certain size. For instance, in areas like North Dakota, pole barns can no longer be built legally according to local laws. However, special allowances exist for smaller agricultural structures. A farm structure under 465 square meters in size could be permissible without a permit if used for agricultural purposes on a 5ha farm, provided it does not fall within an area of special protection.

Personal Structures
Construction of dog houses, shelters, or storage sheds can often be performed without a permit depending on their function. For example, a simple dog house can be built without electrical or plumbing installations. However, as soon as these amenities are added, the project becomes subject to building codes and might require a permit.

Legal Considerations

While building a small shed or storage unit may not attract immediate attention, the county or city still regularly checks for illegal structures using aerial surveys. This is done for safety reasons and also to generate revenue through fines. Around 112 feet, you may be able to build a structure without a permit in certain parts of the United States, such as California, where the author personally built a new pump house recently.

Regional Variations

The local regulations and zoning codes can significantly impact what you are allowed to build and the size of the structure. For example, in regions like the Northwest United States, a garden shed might be acceptable, but other areas in the same state may require permits. In smaller, unincorporated towns, you might be allowed to construct a garage without complaints, but larger structures or those in more controlled environments would likely require permits.

Conclusion

Without a clear understanding of the local laws and regulations, it is challenging to definitively state what is permissible. Building without the proper permits can lead to various penalties and complications. It is always best to check with local authorities and ensure compliance with zoning and building codes.
