6. Copy of a Sanitary Permit or Occupancy Affidavit

  • If you are adding a bedroom, you will also need to provide us with a copy of your sanitary permit showing how many bedrooms your septic is rated for. 

  • If adding a bedroom puts you over your septic rating, you will need to obtain an Occupancy affidavit from the County in which the project is located.

7. CSM (Certified Survey Map) or Plat Map showing setbacks

  • Obtain a CSM from the Register of Deeds at the County (You will find your setback information on this.)  If one is not available for your property, you will need to contact the zoning administrator to see what the property is zoned and what your setbacks are. If your project is zoned by Pierce County,  this is provided on your Land Use Permit. 

8. Site Plan

  • The site plan should detail addition placement to the existing structure, any other structure locations, the well location, septic area, drainage easements, property easements, driveway location, utility placement and any other pertinent information.  All distances must be clearly labeled to determine if setbacks are met. This includes distances from the new house to any roads,  lot lines,  well, septic, driveway, easements and any other other structures   You may also show Erosion Control on this site map


9.  Land Use/Zoning/Conditional Use Permit, If Needed

  • It is up to the applicant to make sure that all zoning regulations are being followed.  This includes but is not limited to making sure there are not restrictions on structure use or  structure location due to physical landscape of the lot (i.e. slopes, ponds, rivers, easements, protected areas....) Your building permit only addresses construction codes etc.  Anything relating to the above is outside All Croix's responsibility.   If you are unsure who to contact about zoning,  click here.
