A permit will also help to establish a record of the construction and remodeling history of your property. Please see our page about permit fees to calculate how much your particular permit will cost. We do not currently charge for plan review. Make sure you know the address of the property. If you are having a contractor do part or all of the work, make sure you ask them if they will be obtaining the permit.
Many properties have surveyor's pins buried along the lines.
If you know approximately where your boundaries are you can rent a metal detector and find those pins. If not, or if there is a dispute about the lines, you will probably need to hire a professional surveyor to determine your actual property lines. I'm building a shed. If your shed will be more than 120 square feet then it does need a permit. In addition, you must be at least 3 feet from the rear or side property lines.
