A building permit is required any time a structure is built; the size of a structure is altered; or a structural alteration is performed. Exceptions include siding, guttering or shingles. Digging out of crawl spaces and basements is allowed without a permit if and only if the exterior dimensions of the building do not increase. A permit for pouring concrete is not needed as long as the concrete is flat, with no curbs or walls (non-foundation work) and said pouring is no more than 8 inches above the existing grade. Building permits are not needed if provided for elsewhere in the zoning ordinance.

For the purpose of this chapter, all land within the corporate limits, and not being under any other zoning jurisdiction is hereby designated on the Comprehensive Zoning Map pursuant to § 153.001 as being in one of the following districts:

Unless otherwise indicated on the Comprehensive Zoning Map, the boundary lines of the districts follow lot lines, center lines of streets, alleys or railroad right-of-ways, or such center lines extended, center lines of creeks or the corporate limit lines as existing at the time of adoption of this chapter.

No building or land shall hereafter be used and no building, structure or part thereof shall be erected, moved or altered unless for a use expressly permitted by and in conformity with the regulations for the district in which it is located.

All territory which may be hereafter added to the zoning jurisdiction (through extension of the one and one-half mile contiguous zoning area by virtue of annexation) shall be considered as being in the AG District until and unless otherwise designated on the Comprehensive Zoning Map or amended as specified in the procedure in § 153.365.

Any lawful use of land or structures existing at the time of adoption of this chapter, may be continued subject to the limitations set forth in §§ 153.021 through 153.023.

No structural expansion or alterations shall be made in a building or other structure containing a nonconforming use except:

No non-conforming use shall be reestablished after having been discontinued for 12 continuous months. Vacation of premises and building or non-operative status shall be evidence of a discontinued use. Upon such determination of the Zoning Enforcement Officer, a letter of notification shall be issued becoming effective 12 months from the date of notification.

No different type of non-conforming use may be substituted for any other non-conforming use.

On any corner lot in all districts, except the B-1 District, there shall be no obstruction to traffic visibility within 30 feet of the intersection of the two streets, measured from the property lines of the corner lot.
