17.35.010 Intent.
A. It is the purpose and intent of this chapter to accommodate various types of unique and innovative housing forms which are usually based upon a concept of reducing the area of individually owned lots, and grouping such lots together to utilize the total space more efficiently within the subdivision by creating common open spaces, scenic and recreational areas, and other spaces which would compensate for the reduction of land area contained within the individually owned lot.
B. Specifically, this chapter is designed to allow the grouping of separately owned one-unit dwelling units into a group of townhouses in such a manner as to make efficient, economical, and aesthetically pleasing use of land so restricted that the same will be continually well maintained to preserve the health, welfare, safety, and convenience of the surrounding neighborhood and insure a reasonable amount of open space and architectural variety. (Ord. 276 Exh. 1, 2024)
17.35.020 Design standards.
The following standards have been developed and apply to a variety of such attached and semi-detached single-unit housing forms including but not limited to townhouses or any other similar designation. All other provisions contained in the town zoning code are applicable to these types of housing forms unless specifically noted in this chapter.
A. No two townhouse dwelling units shall be served by the same interior or exterior stairway or by the same exterior door.
B. No townhouse lot shall contain an area of less than one thousand six hundred square feet and a minimum lot and building width of not less than twenty feet.
C. The minimum size of the site to be developed for townhouse units shall be five thousand square feet. (Ord. 276 Exh. 1, 2024)
17.35.030 Final landscape and site improvement plan.
A detailed final landscape plan and final site improvement plan shall be submitted and approved by both the planning official and building official prior to the issuance of a building permit. Final approval shall include but not be limited to the following:
A. Conformance to the approved site plan;
B. Inclusion of appropriate plant materials;
C. All other requirements as set forth in Chapter 17.31. (Ord. 276 Exh. 1, 2024)
17.35.040 Architectural treatment.
In any townhouse division, architectural treatment shall be as follows: The facades of townhouses in a group shall be varied by changed front yard setbacks and variation in materials or design so that no more than two abutting townhouses will have the same front yard setback and the same or essentially the same architectural treatment of facades and roof lines. (Ord. 276 Exh. 1, 2024)
17.35.050 Maintenance of common area.
A. Provisions satisfactory to the town council shall be made to assure that nonpublic areas and facilities for the common use of occupants of a townhouse development, but not in individual ownership of such occupants, shall be maintained in a satisfactory manner without expense to the general taxpayers of the town. To this end, the incorporation of an automatic membership owners’ association created under recorded land agreements will be required for the purpose of continuously holding title to such nonpublic areas and facilities, and levying assessments against each townhouse lot, whether improved or not, for the purpose of paying the taxes and maintaining such nonpublic areas and facilities, which may include but not be limited to recreational areas, off-street parking bays, private streets, sidewalks, street lights, and common open and landscaped area.
B. Such assessments shall be a lien superior to all other liens save and except tax liens and mortgage liens, provided the mortgage liens are first liens against the property encumbered thereby, subject only to tax liens, and secure indebtedness which are amortized in monthly or quarter-annual payments over a period of not less than ten years. Other methods may be acceptable if the same positively provide for the proper and continuous payment of taxes and maintenance without expense to the general taxpayers. The instrument incorporated by such provisions shall be approved by the town council and shall be recorded in the public records of the county if satisfactory to the town council.
C. In the event that this or a similar entity fails to maintain the common area in accordance with the landscaping plan approved by the town council, or should the entity fail to maintain the common area in a reasonable condition and state of repair, the determination of such failure to be made by the building official, the town council may, at its option through its own agents or by independent contractor, enter the common area for purposes of maintenance thereof, together with an additional charge of twenty-five percent of the costs for management fees, such costs to constitute a lien upon each and every lot in the project.
