FAQ ## FAQ on Drafting Services in Los Angeles County It’s not allowed to own, use, or live in a building that hasn’t been properly permitted. An “unpermitted structure” is any building — or part of one — that was built, remodeled, expanded, moved, connected to utilities, or otherwise altered without first getting the required permits from the Building Official, as outlined in [Section 106.1](https://up.codes/viewer/los-angeles-county/ca-building-code-2022/chapter/new_duped_1/administration#new_106.1). This also applies to projects where a permit was issued but has since expired before the work was completed. - What is an unpermitted structure in Los Angeles? Drafting costs depend on your project’s scope and complexity, but most projects typically range from 3–4 percent of the total construction budget. We provide a clear upfront estimate, so you know what to expect before we begin your plans. - How much do drafting services cost in Los Angeles? In most cases, you can build a detached structure under 10 square meters (108 square feet) without a permit, as long as it isn’t attached to another building, isn’t connected to utilities, and doesn’t exceed 4.3 meters (14.1 feet) in height. - What’s the largest structure I can build without a permit in Los Angeles? --- Streamline Design & Permitting — [https://streamlinedesigngroup.com/service-areas/drafting-services-los-angeles-county](https://streamlinedesigngroup.com/service-areas/drafting-services-los-angeles-county)
