When applying for a building permit in most cities or counties, a “site plan” or “plot plan” is required as part of the building plans prepared by an architect or civil engineer. The PLOT PLAN shows the existing conditions and the proposed construction with distances to the property lines known as “setbacks”.
Some building departments will accept the site plan on the Improvement Location Certificate type of survey under certain conditions. Jefferson County’s Site Plan Requirements, changed on January 1, 2019, allow the use of the ILC in the mountains if the property is over one acre. If not in the mountains, the minimum square footage of the lot must be greater than 8,000 square feet.
Call us to discuss your project and see it the ILC can be used in your city or county.
For drainage or other site considerations, a topographic survey may be ordered by the architect or engineer for foundation location. Some jurisdictions also require an Improvement Survey Plat for a plot plan.
We supply this information to your architect or engineer for the design of a new house, garage or other structure and it usually becomes the first page of your construction documents and plans.
