4.3 In the past year the City has processed a number of requests for larger accessory structures that have been proposed on larger than normal (85 foot by 110 foot) residential lots. The Community Development Staff has been able to legitimize these requests, with the support of the Planning Commission. The Dahmann request fits into the category. 5.0 STAFF C01�I1�IENTS/FINDINGS: 5.1 Section 1004.O1A5 states: Overall Area: The overall area of an attached garage and detached accessory building(s) sha11 not exceed the e�terior dimensional footprint of the principal structure, excluding any attached garage footprint. The combined accessory building square footage (1,419) does not exceed the exterior dimensional footprint of the principal "residential" structure (1,599 est.) on the premises. 5.2 Section 1004.0 lA3 states: Detached Accessory Building Size Limit: Tota1 detached accessory building area sha11 be limited to foriy percent (40%) of a required rear yard area, up to a ma�mum size of eight hundred si�ty four (864) square feet. The foriy percent (40%) rear yard limitation is calculated by taking the width of the subject lot or parcel and multiplying it by the required rear setback depth of thiriy feet (30'), then multiplying that number by 0.4 or foriy percent (40%). Under this code requirement 1�Ir. Dahmann has a rear yard building area allowance of 1,539 square feet. 5.3 Section 1004.0 lA6 (Ma�mum Tota1 Surface Area) affords a residential properiy owner an impervious lot coverage of 30%. Impervious items include driveway, sidewalk, patio and all covered structures. The Community Development Staff has determined that the Dahmann parcel is limited to 11,476 square feet of impervious area. 5.4 Section 1004.01A2 allows one garden shed that does not exceed 120 square feet and is not counted as an accessory building (2 accessory buildings are allowed). However, the roof surface is included in the overall calculation of impervious surface. 5.5 Summarizing, the staff has determined the Code would allow accessory structures up the ma�num size of 1,008 square feet. However, the rear yard limit and principal structure footprint would allow a larger square footage. 5.6 Section 1013.02 requires the applicant to demonstrate a physical hardship and to demonstrate that no practical alternatives exist that would reduce the need for a variance. Variance may be granted where the strict enforcement of the literal provisions of the ordinance would cause "undue hardship". The granting of a variance sha11 only occur when it can be demonstrated that such an action will be in keeping with the spirit and intent of the ordinance. 5.7 "Undue hardship" as used in connection with the granting a variance means the properiy in question cannot be put to a reasonable use if used under conditions allowed by the official controls, the plight of the land owner is due to circumstances unique to the properiy not created by the land owner, and the variance, if granted, will not alter the essential character of the locality.
