I. DESCRIPTION OF THE PROPOSAL
The Applicant requests a Special Use Permit for a Guest House on the subject property which is
defined in the Zoning Resolution as an accessory, detached building, which is designed and used to
house nonpaying visitors and guests of the occupants of the main building of the site. A guest house
is contemplated as a special use in the ARRD zone district.
II. BACKGROUND
The Applicant was cited for an illegal dwelling unit in a garage on the property as a zoning
violation by the County Zoning Enforcement Officer on February 13th, 2003. The Applicant also
installed a full second kitchen in the basement of the primary dwelling unit on the property which,
in effect, creates an illegal duplex. [Staff conducted a site visit to the property on 3/19/04 and
verified the kitchen has not been removed and continues to be a violation of the County's zoning
code.]
III.APPLICABLE REGULATIONS
A. Special Use Permits are subject to the standards set forth in Section 5.03 of the Zoning
Resolution. This section states that utilities adequate to provide water and sanitation service,
street improvements, and design of the proposed use to minimize impact through various means
shall be provided. Impacts are generally expected to be minimal due to the lot size and the fact
that the structure is already in place on the property.
B. Zoning Resolution: A Guest House is a special use in the ARRD zone district pursuant to
Section 3.02.03 of the Zoning Resolution of 1978. The application must address the general
1
Special Use Permit requirements in Section 5.03 as well as the specific Special Use Permit
standards that apply to a Guest House in Section 5.03.025. The requirements / standards are
listed below in bold italics followed by a Staff response:
General Special Use Permit Requirements (Section 5.03)
1) Utilities adequate to provide water and sanitation service based on accepted
engineering standards and approved by the Board of County Commissioners shall
either be in place or shall be constructed in conjunction with the proposed use.
Staff Finding
Regarding domestic water, the property has a well permit from the Division of Water
Resources augmented by a West Divide Water Conservancy District contract which is
activated for 1 primary dwelling unit and one accessory dwelling unit. These improvements,
as they relate to the guest house (water line and septic line) were installed during the
construction of the garage under the garage permit (#8197) and are therefore presently in
place.
Regarding wastewater, when the Applicant constructed the primary unit (a manufactured
home with unfinished walk -out basement), an engineered septic system was permitted
(#3519) and installed with capacity for 5 bedrooms (see "general notes" from the original
building permit set as Exhibit G). Since this was completed, the Applicant obtained a
second building permit to finish the basement which included 3 (three) bedrooms. At
present, the Applicant has constructed an illegal dwelling unit in the garage with 1 (one)
bedroom. Both of these units are hooked into the one system. The Assessor's property
information shows the primary dwelling unit has 7 bedrooms. This is a significant issue
because the number of bedrooms exceeds what is legally permitted and engineered in the
septic system. This could also result in a "discharge to groundwater" issue if the system
fails. (The property also fronts the Colorado River.) Therefore, based on the inadequacy of
the septic system, the proposal does not meet this requirement.
2) Street improvements adequate to accommodate traffic volume generated by the
proposed use and to provide safe, convenient access to the use shall either be in place
or shall be constructed in conjunction with the proposed use;
Staff Finding
There appears to be ample area for parking on the property for a single-family dwelling and
a guest house. The need for parking or improvements due to associated traffic generated
from a guest house is typically much less than a single-family dwelling.
3) Design of the proposed use is organized to minimize impact on and from adjacent
uses of land through installation of screen fences or landscape materials on the
periphery of the lot and by location of intensively utilized areas, access points,
lighting and signs in such a manner as to protect established neighborhood
character;
