view to join tables

I need to create a view to join 13 tables. The objective is to have one view that allows basic queries on permit types (building, electrical, plumbing, signs, mechanical....). Each type of permit and it associated information is stored in separate tables, and a column in each table
(permit_type_code) indicates the type of permit.
 

The common columns in each table are:  

Group_num

Permit_type_code

Permit_num

Perm_contractor_name

Perm_work_type_code_descr

Perm_authorized_work

Perm_c_status  

The tables are named (partial listing):  

Perm_bldg

Perm_elec

Perm_mech

Perm_signs

.....    

Any queries that are currently used are done against the table containing the appropriate permit_type_code. There are separate permit_num's for each permit_type_code. There are 1 or more permit_num's associated with a given group_num.  

I'm not sure if I'm making any sense, but would appreciate any insight from the group.    

Regards,  

Robert Richmond
