Legalize Unpermitted Work

However, there are occasions where the homeowners building without permit from the local authorities. Fortunately, Los Angeles laws allow getting a retroactive building permit if the work meets the minimum local codes and standards without demolishing the entire building or starting from scratch.
Bringing an unpermitted build up to code, however, is a complex and lengthy endeavor. You will need to acquire all the necessary permits from the Los Angeles Department of Building and Safety (LADBS) and a significant amount of additional work, depending on the nature and scope of the construction. Getting a post-construction permit could be exhausting and perplexing for many homeowners. Therefore, it is advisable to seek the stewardship of a local, licensed design-build firm that has extensive experience in dealing with unpermitted structures.

Do I Need to Permit My Conversion Without Paperwork Before Selling My House?
Not necessarily! However, selling a house that has an unpermitted conversion or any other kind of work done without necessary paperwork is difficult. This is because people are reluctant to buy a home that has unpermitted construction because of safety concerns and the time and money required in the process of legalizing it. If you want to sell your house as-is, you will have to offer it for a lower price than its market value.
Keep in mind that being the homeowner, you will be legally obliged to disclose unpermitted work to the buyer. Not doing so may result in legal repercussions when it is discovered by them later.
