REMODELS and ADDITIONS

 

Remodel projects and additions vary greatly in size and scope.  It is always best to contact the Building Department to find out what is required prior to submitting your permit application.  Depending on what changes you are making, you may be required to submit an Original Grade plan with your application.  All building and zoning code heights are measured from the original grade lines (not the existing grade.)

 

Permit applications must be accompanied by the following:

  • A completed permit application form.
  • Two (2) copies of all plans:
    Plans shall be drawn on paper at least 17" x 22" and shall be to scale (preferable 1"=10').  Include a North arrow and a title block with the Owner's name, the site address, and a drawing and revision number.  If applicable, include the name, address and phone number of the firm responsible for the drawings.
  • Two (2) copies of supplemental documentation:
    These are things such as structural calculations, appliance specification sheets and finish schedules.
  • A check or cash for the plan review fee; this fee is based on your best-guess estimate of the project's value.

Substantial Remodels

If you are planning a significant change to your home, the project may become what we call a substantial remodel.  A substantial remodel for the year 2010 is defined as a project valued over $395,000.

 

A project's value is determined by the Building Official per Clyde Hill Municipal Code Section 108.4.

If your project is a substantial remodel, or if multiple projects during a two-year period exceed the substantial remodel value, then you must bring your property and all buildings into compliance with current zoning codes and current drainage requirements.

 

A pre-application meeting is required for substantial remodel projects.  The architect must attend this meeting.  The homeowner may choose to be present and it is a good idea for the contractor to attend as well.  At this meeting the Building Official will review with you all required setbacks, height limits, lot coverage and other zoning requirements.  The City Engineer will review erosion control, drainage and detention requirements, right-of-way use details and utilties hook-up.  All plans submitted must be stamped by the architect and/or engineer who designed them.

 

Legal-Nonconforming Structures

Many of the homes in Clyde Hill were built or remodeled under old building and zoning codes.  Homes that met previous codes, but do not comply with current codes are referred to as legal-nonconforming structures.
