Comments and Considerations
The subject property consists of 0.258 acres currently improved with a 1,500 sq. ft. single-story house with front and rear covered porches, detached carport, and shed. The applicant is requesting to rezone the property from SF-7.5/12 Single-Family Residential District to PD Planned Development District for single-family residential and accessory dwelling uses on approximately 0.258 acres.
Development Plan and Regulations
The existing 1,500 sq. ft. single-story house with porches will remain, but the carport and shed will be removed. The house, which was built in 1880 and classified as a selected medium-priority house in the City’s Historic Resources Survey, is a wood frame house in the massed plan pyramidal style with a pitched gabled roof. The house includes white vinyl siding with light blue trim. A low stone wall with shrubs was recently added to the front porch. The house is approximately 25’ in height.
Behind the house, a new 1,700 sq. ft. two-story detached accessory structure will be constructed. The building will include a two-car garage on the first floor and two bedrooms and a bathroom on the second floor. The garage will be accessed via an existing drive approach on Alvarado Street.
The applicant proposes the following minimum lot standards:
Minimum Lot Area: 11,250 sq. ft.
Minimum Lot Width: 75’
Minimum Lot Depth: 150’
Minimum Front Setback (principal building): 25’*
Minimum Side Setback (principal building): 10’ exterior*, 5’ interior
Minimum Side Setback (accessory building): 5’
Minimum Rear Setback (principal building): 15’
Minimum Rear Setback (accessory building): 10’
Maximum Lot Coverage: 45%
Maximum Height: The height of the accessory building shall not exceed 25’ or the height of the principal building
Maximum Height of Principal Building: 35’
Maximum Area of Accessory Structure: 1,100 sq. ft. foundation; 1700 sq. ft. under roof
Minimum Residential Floor Area of Primary Building: 1,500 sq. ft.
*Porches are allowed to encroach into the front and exterior side setbacks as shown on the Development Plan
Accessory Dwelling Requirements
In accordance with the standard Zoning Ordinance requirements applicable to accessory dwellings, the occupancy of the accessory dwelling will be limited to domestic servants or caretakers employed on the premises, temporary guests, or family members of the owner of the premises; guests may occupy such dwelling no more than 90 consecutive days in any twelve-month period. In addition, no additional accessory structures will be allowed on the property and the accessory dwelling will not be used as an apartment, separate domicile, or vacation rental/lodging. All utilities will be on the same meter as the main residential building.
Architectural Requirements
No significant changes are proposed for the existing house, however any exterior reconstruction or remodeling of the principal building must be compatible with its historic character. The exterior façade of the principal building is a wood frame structure with vinyl siding with cedar posts and a pitched gabled roof. The accessory structure will be designed in a similar manner to the primary structure, with cementitious siding and a hipped roof with gables on all four sides. The siding of the accessory structure will match the siding of the primary structure in terms of style and the exterior paint colors of the buildings will be compatible.
Access and Parking
The property will be served by an existing drive approach on Alvarado Street. A minimum of 2 off-street parking spaces will be provided per the development regulations, however the proposed 2-car garage and oversized driveway will likely be able to accommodate more than 2 vehicles.
As the City has a goal of adding sidewalks in the downtown area as development occurs and this development will increase the gross floor area on the property by more than 50%, staff requested that the applicant add sidewalks along the public street frontages. The applicant is requesting to be excepted from this requirement since there are currently no other sidewalks on this block and this is only a 1-lot development to add an accessory dwelling.
Landscaping and Screening
The three existing trees on the property will be retained and the 4” pecan tree near the driveway will be protected during construction. No additional trees will be planted. The 6’ existing metal fence along the north side of the property and the 4’ chain link fence along the west side of the property will also remain.
Recommendation
The proposed development will allow for the preservation of the existing historic structure, while also removing accessory structures that do not match or complement the historic structure. While the proposed accessory structure is larger, taller, and closer to property lines than what the Zoning Ordinance would allow, the new building better matches and complements the existing structure while not detracting from or overshadowing it. The new building will allow for enclosed parking and additional living space that could increase the functionality and value of the property, without making additions to the principal building that could affect its structural integrity or historical character. The development also preserves the existing trees and allows the existing drive approach to be utilized without major modifications. Furthermore, the Land Use Plan and Downtown Development Strategies encourage higher densities and multi-unit housing in this part of downtown; the increase in intensity by adding an accessory dwelling aligns with those goals. Staff recommends approval with the condition that sidewalks be added along S. 2nd Ave. and Alvarado St.
