§ 750.707 Nonconforming signs. ( a ) *General.* The provisions of § 750.707 apply to nonconforming signs which must be removed under State laws and regulations implementing 23 U.S.C. 131. These provisions also apply to nonconforming signs located in commercial and industrial areas within 660 feet of the nearest edge of the right-of-way which come under the so-called grandfather clause contained in State-Federal agreements. These provisions do not apply to conforming signs regardless of when or where they are erected.
( b ) *Nonconforming signs.* A nonconforming sign is a sign which was lawfully erected but does not comply with the provisions of State law or State regulations passed at a later date or later fails to comply with State law or State regulations due to changed conditions. Changed conditions include, for example, signs lawfully in existence in commercial areas which at a later date become noncommercial, or signs lawfully erected on a secondary highway later classified as a primary highway.
( c ) *Grandfather clause.* At the option of the State, the agreement may contain a grandfather clause under which criteria relative to size, lighting, and spacing of signs in zoned and unzoned commercial and industrial areas within 660 feet of the nearest edge of the right-of-way apply only to new signs to be erected after the date specified in the agreement. Any sign lawfully in existence in a commercial or industrial area on such date may remain even though it may not comply with the size, lighting, or spacing criteria. This clause only allows an individual sign at its particular location for the duration of its normal life subject to customary maintenance. Preexisting signs covered by a grandfather clause, which do not comply with the agreement criteria have the status of nonconforming signs.
( d ) *Maintenance and continuance.* In order to maintain and continue a nonconforming sign, the following conditions apply: ( 1 ) The sign must have been actually in existence at the time the applicable State law or regulations became effective as distinguished from a contemplated use such as a lease or agreement with the property owner. There are two exceptions to actual existence as follows: ( i ) Where a permit or similar specific State governmental action was granted for the construction of a sign prior to the effective date of the State law or regulations and the sign owner acted in good faith and expended sums in reliance thereon. This exception shall not apply in instances where large numbers of permits were applied for and issued to a single sign owner, obviously in anticipation of the passage of a State control law.
( ii ) Where the State outdoor advertising control law or the Federal-State agreement provides that signs in commercial and industrial areas may be erected within six (6) months after the effective date of the law or agreement provided a lease dated prior to such effective date was filed with the State and recorded within thirty (30) days following such effective date.
( 2 ) There must be existing property rights in the sign affected by the State law or regulations. For example, paper signs nailed to trees, abandoned signs and the like are not protected.
( 3 ) The sign may be sold, leased, or otherwise transferred without affecting its status, but its location may not be changed. A nonconforming sign removed as a result of a right-of-way taking or for any other reason may be relocated to a conforming area but cannot be reestablished at a new location as a nonconforming use.
( 4 ) The sign must have been lawful on the effective date of the State law or regulations, and must continue to be lawfully maintained.
( 5 ) The sign must remain substantially the same as it was on the effective date of the State law or regulations. Reasonable repair and maintenance of the sign, including a change of advertising message, is not a change which would terminate nonconforming rights. Each State shall develop its own criteria to determine when customary maintenance ceases and a substantial change has occurred which would terminate nonconforming rights.
( 6 ) The sign may continue as long as it is not destroyed, abandoned, or discontinued. If permitted by State law and reerected in kind, exception may be made for signs destroyed due to vandalism and other criminal or tortious acts. ( i ) Each state shall develop criteria to define destruction, abandonment and discontinuance. These criteria may provide that a sign which for a designated period of time has obsolete advertising matter or is without advertising matter or is in need of substantial repair may constitute abandonment or discontinuance. Similarly, a sign damaged in excess of a certain percentage of its replacement cost may be considered destroyed.
( ii ) Where an existing nonconforming sign ceases to display advertising matter, a reasonable period of time to replace advertising content must be established by each State. Where new content is not put on a structure within the established period, the use of the structure as a nonconforming outdoor advertising sign is terminated and shall constitute an abandonment or discontinuance. Where a State establishes a period of more than one (1) year as a reasonable period for change of message, it shall justify that period as a customary enforcement practice within the State. This established period may be waived for an involuntary discontinuance such as the closing of a highway for repair in front of the sign.
( e ) *Just compensation.* The States are required to pay just compensation for the removal of nonconforming lawfully existing signs in accordance with the terms of 23 U.S.C. 131 and the provisions of subpart D, part 750, chapter I, 23 CFR. The conditions which establish a right to maintain a nonconforming sign and therefore the right to compensation must pertain at the time it is acquired or removed.
