B. 
Lot size and density.
(1) 
Lots serviced by a municipal water system and municipal sewerage system shall have at least 1/2 acre for the first unit that may be located thereon and at least 10,000 square feet for each additional unit on the same lot.
(2) 
Lots serviced by a municipal water system shall have at least 1/2 acre for each unit that may be located thereon.
(3) 
Lots serviced by a municipal water system and a municipal sewerage system which qualify as infill development shall have at least 10,000 square feet per unit.
(4) 
The minimum lot size for keeping domestic farm animals shall be one acre.
(5) 
All other lots shall have at least one acre for each unit that may be located thereon.
C. 
Structure lot coverage shall not exceed 15% of total buildable area for new development. Parcels designated for the primary use of non-transient residential occupancy or infill development are not subject to structure lot coverage limitations.
D. 
Frontage. All lots must front on a state or Town highway with a Class I, II, III, IV or V classification, a private road constructed to Town standards as required by the Planning Board or a Class VI road proposed to be improved as stipulated by the Planning Board. To qualify as frontage, the lot must have access rights to the subject highway or road. The minimum distance for frontage on a road shall be:
(1) 
One hundred fifty feet.
(2) 
One hundred feet for lots which front entirely on cul-de-sacs which meet the design requirements set forth in Chapter 130, Subdivision of Land, Article X, Detail #4, or lots qualifying as infill development.
E. 
Setbacks. The minimum front setback shall be 25 feet from a platted right-of-way, or 100 feet from the platted right-of-way of the North-South Road between the extension of the center line of Barnes Road and the center line of Depot Road and the minimum side or back setback shall be 10 feet.
F. 
Structure and building height. Structure height is restricted to achieve several purposes. The Town is economically dependent upon tourism and attracts visitors with its rural character and mountainous setting. Maintaining the traditional scale and style of structures aids in preserving the character of the Town. Peaked roofs are encouraged because it is the traditional roof style in the Town. (Care has been taken to prepare language which does not unduly encourage the use of flat-roof buildings.) The height restriction keeps structures and buildings below treetop level, which is typically from 60 feet to 100 feet for mature maple, beech, birch and pine trees. Structure height below treetop level helps maintain the rural atmosphere and preserve the viewsheds throughout the Town. In addition, the height limit minimizes difficulty in providing fire protection. The following shall apply throughout the Town:
(1) 
Structure height shall not exceed 45 feet for any structure, except wind energy systems permitted in accordance with Chapter 179 of the Conway Code. For properties located in the North Conway area north of North Conway Village, structure height shall not exceed 40 feet.
(2) 
Building height shall not exceed 35 feet. For properties located in the North Conway area north of North Conway Village and structures on the western side of White Mountain Highway, building height shall not exceed 30 feet. Church steeples may be allowed to exceed 55 feet in height by special exception on application to the Zoning Board of Adjustment as approved after a hearing with appropriate conditions imposed thereon, provided that:
(a) 
The space enclosed in the steeple is not usable floor space other than for the maintenance and structural purposes of the steeple.
(b) 
The height of the steeple is appropriate to the design and size of the church.
G. 
Conditional use permits. Conditional use permits (CUP) may be granted by the Planning Board to allow increases to structural lot coverage and unit density standards. Approval of a CUP is dependent on the applicant meeting specific conditions and demonstrating that proposals maintain the character, scope, and scale of neighboring properties.
Prior to submission of a formal Planning Board application, any proposal requesting a CUP shall be subject to design review. A formal application will not be considered complete without preliminary review.
(1) 
Adaptive reuse. Adaptive reuse projects are intended to revitalize existing structures which will include restricted non-transient residential units in all or any portion of an eligible structure.
(a) 
Adaptive reuse eligible structures. The provisions of this conditional use permit shall apply to all or any portion of an existing structure constructed prior to 1978 or vacant for a period of at least 10 years.
(b) 
Density.
[1] 
Eligible structures with a footprint of 10,000 square feet or less, shall not be subject to unit density requirements of the underlying district. All units associated with the density relief shall be restricted for non-transient residential occupancy.
[2] 
For eligible structures with a footprint of greater than 10,000 square feet, density of dwelling units restricted for non-transient residential occupancy shall not exceed 18 units per acre.
[3] 
Proposed unit counts may be reduced by the Planning Board if potential impacts to the community cannot be mitigated other than by reducing site density.

Structures which are greater than 50 years of age must provide a review completed by NH Division of Historical Resources. The Planning Board may require historically significant properties to maintain or restore valuable architectural qualities and design features.
(g) 
Findings. In addition to other requirements of this chapter or other applicable regulations, including Site Plan and Subdivision review, the Planning Board shall also find:
[1] 
The proposed Adaptive Reuse Project will not be detrimental to the safety, value, or welfare of surrounding properties or residence;
[2] 
That the Adaptive Reuse Project will be designed to current building code standards; and
[3] 
The Adaptive Reuse Project aligns with the intent of the Master Plan and is determined a benefit to the community.
(2) 
The Planning Board may grant a conditional use permit to allow up to 14 dwelling units per acre in the Highway Commercial District with the following conditions:

Developments with a primary vehicular access on collector or local roads which direct vehicles to signalized or adequately controlled intersections may be permitted up to a 10% increase in structural lot coverage.
[1] 
A traffic study must be provided to demonstrate potential traffic impacts and the ability for congestion to be mitigated.
[2] 
The applicant must also demonstrate that collector or local roads would not be overburdened with increased traffic flow. Off-site improvements may be necessary to address impacts to infrastructure, provide traffic calming measures, or complete necessary intersection upgrades.
(f) 
Developments which provide shared parking for a minimum of 25% of the on-site parking demand may be permitted up to a 5% increase in structural lot coverage.
[1] 
The applicant must provide easements or other legal documentation to demonstrate the shared parking rights.

[1] 
The percentage of additional structural lot coverage granted will be determined on the significance of the nonconformity being abandoned. Higher percentages, up to 10%, may be granted when conformance clearly mitigates an impact to an abutter or the community.
(j) 
Transfer of developmental rights.
[1] 
The purpose of the transfer of development rights incentive is to balance new impervious coverage with the protection of watersheds and drinking water sources within the Town of Conway.
[2] 
Developments may elect to purchase credits to increase the permitted structural lot coverage as defined in § 190-20.C. The Development Transfer Credits shall be obtained and utilized pursuant to Chapter 144, Transfer of Development Rights.
[3] 
Development transfer credits must be used to obtain structures or land area within the floodplain; preserve or restore shoreland, wetland and waterbodies buffers; or protect drinking water sources within the Saco or Swift River watershed in the Town of Conway.

In no case, however, shall such increases cause any sign message area to exceed 80 square feet. The applicant shall submit a satisfactory written declaration, to be recorded at the Carroll County Registry of Deeds, in which the owner, its heirs, successors and assigns agree that, if the frontage of the property is subsequently reduced below that amount required for the bonus granted, the sign shall be removed or replaced with a sign which fully conforms with the provisions of this chapter; and that no subdivision of a lot shall be permitted unless a freestanding sign erected under this provision continues to conform to this provision; and such agreement must be legally enforceable by the Town of Conway.
