Many different permits require a site plan (sometimes called a “plot plan"), which is a detailed and accurate
map of the subject property. To avoid delays in the review and approval of your project, a complete and
accurate site plan drawn to scale is required. A complete site plan will include all the site features and
information listed below (depending on your site and scope of project, of course). Assume all items are
required unless they are not applicable (N/A) or not relevant to your project or project site.
Property information, including relevant zoning code, topography, site features, etc., for your property may be
obtained from
The last page includes a sample site plan, showing a majority of the items listed below.
Whenever new construction or exterior work is proposed, it is important to identify the piece of property
where the work is to occur, the relationship of that work to nearby properties and streets, and the scope of
the work that is to occur. It is recommended that the site plan be prepared by a licensed professional.
Required N/A
The property owner's name, the assessor's parcel number and the site's address.
A North arrow indicating the direction North.
The map scale. A scale of 1”=10' is typical, but others may be acceptable.
All property lines, property corners, easements (utilities, access, etc.), and site dimensions.
Building outlines to identify location of exterior walls, bay windows, chimneys, etc.
The dimensions between buildings, and from buildings (including overhangs and projections)
to all property lines.
Label structures to be demolished, such as detached garage, shed, single family house.
The locations and square footage of all existing and/or proposed driveways, walkways,
decks, patios and other impervious surfaces, indicating surface materials and dimensions.
Clear distinction between any existing and proposed buildings or site features.
All streets and alleys, with street names. Note the nearest cross street.
The location, dimensions and square footages of all existing and proposed buildings.
The use of each building or area (garage, residence, ADU, shop, shed, etc.).
Finished grades, any steep slopes (15% or greater) and/or fill areas.
The height of fences, decks, retaining walls, rockeries and other similar elements.

elevations at midpoints of wall segments, average building elevation calculations, and
benchmark elevations. If provided on a separate sheet, indicate which sheet.
