## Slide 1
Public Hearing: Legislative Hearing Providing for the Amendment of Title 4, Chapters 1, 3, 4, and 6 of Moscow City Code Regarding Amendments to Single-Family Dwellings, Two-Family Dwellings, and Bed and Breakfast Inns
Planning and Zoning Commission
May 13, 2026
## Slide 2
Background
The City of Moscow Community Development Department over the past couple years has observed the evolution of building plans being submitted for two-family dwellings which increasingly have multi-family elements
Recent building permit applications and construction plans have been submitted for structures represented as two-family dwellings, but which are designed and leased as multi-family dwellings
It appears the structures are being represented as two-family dwellings to avoid the ADA, life-safety, off-street parking, and other Federal, State, and local building standards that apply to multi-family dwellings
## Slide 3
Background
Multi-family dwellings (3 or more dwellings)
- Fire alarm and suppression systems
- ADA accessible units with accessible site amenities
- Off-street parking and common open space
Two-family dwellings
- No fire alarm or suppression system requirements
- Not subject to ADA requirements
- Have a much lower parking requirement and no ADA parking is required
## Slide 4
Building Codes
State of Idaho requires municipalities to adopt the building codes that are adopted by the state
- 2018 International Building Code
- Covers multi-family and commercial buildings
- Municipalities may adopt stricter standards
- 2018 International Residential Code
- Covers single- and two-family dwellings
- Municipalities are permitted to adopt stricter standards only in certain chapters
- Currently fire sprinkler systems and/or fire alarm systems are not required and municipalities are not allowed to require them

A second kitchen may be permitted with a recorded deed restriction, so long as the property is used as a single-family dwelling only with no physical separation established to separate living quarters within the dwelling which would allow the structure to be used and occupied by two families living independently of each other. The classification “single family dwelling” shall include any home in which eight (8) or fewer unrelated mentally and/or physically handicapped or elderly persons reside; and which is supervised. Resident staff, if employed, need not be related to each other or to any of the mentally or physically handicapped or elderly persons residing in the home. No more than two (2) such staff shall reside in the dwelling at any one (1) time.
## Slide 15
Definitions
51. Dwelling Unit. A building or portion thereof providing complete housekeeping facilities for one (1) family. Housekeeping facilities provide permanent provisions for living, sleeping, eating, cooking, and sanitation, and shall be limited to one (1) kitchen and two (2) washer and dryer sets per dwelling unit unless otherwise permitted by this Code. The term "dwelling" shall not be deemed to include motel, hotel, tourist home, bed and breakfast inn, or boarding house.
## Slide 16
Definitions
76. Kitchen. Any rooms used or intended or designed to be used for cooking and/or preparation of food. That portion of a dwelling unit devoted to the preparation or cooking of food for the purpose of consumption by residents of the dwelling unit.

## Slide 21
Design requirements for parking lots
Parking lots and spaces shall be designed such that their use will not require backing movements or other maneuvering within a street right of way. Parking spaces provided for single family and two (2) family dwellings are exempt from this requirement, unless the street being accessed is a designated arterial street or there is more than one (1) detached single-family dwelling or two (2) family dwelling upon a single lot. The continuation, alteration, expansion, relocation, re-construction, or replacement of a single or a two (2) family dwelling, for which the parking requires backing or maneuvering within a designated arterial street right-of-way, shall be allowed where such situation existed prior to May 1, 2003, notwithstanding the nonconformity regulations of this Zoning Code. Additional parking required as a result of the expansion, alteration, reconstruction, or re-placement of any such two (2) family dwelling shall meet the parking design standards required at the time of the building permit application. Where backing movements are proposed within an alley right-of-way, a sidewalk with a minimum width of three feet (3’) shall be provided adjacent to the parking lot between the parking lot and the use served by the parking lot.
## Slide 22
Design requirements for parking lots
Parking lots and spaces shall be designed such that a vehicle shall not be required to cross another parking space to gain access to a required parking space (tandem configuration) except for parking spaces serving single-family, two (2) family, twinhome, and townhouse dwellings. Parking serving more than one (1) detached single-family dwelling or two (2) family dwelling upon a single lot shall not be permitted to be tandem, except as provided below. Tandem parking may be allowed for multi-family dwellings or more than one (1) detached single-family dwelling or two (2) family dwelling upon a single lot under the following conditions:
- The purpose of the parking design is to provide enclosed garages for the multi-family dwelling resident use;
- The tandem parking spaces (the parking space within the garage and in front of the garage) are assigned and furnished for use by the occupants of a single-family dwelling unit without separate, additional compensation; and
- No more than fifty percent (50%) of the required parking may be provided in a tandem configuration.
## Slide 23
Off-Street Parking Schedule
Parking spaces required for designated uses in all zoning districts, except within Section 4-6-5(E)(4) below, are established as follows:
Compact Spaces: An allowance of thirty five percent (35%) of the total number of spaces required may be identified and used as compact car spaces. These spaces shall be conveniently located and provided with adequate signage.
Fractional Requirements: Fractional requirements shall require one (1) space.
Area Calculation: Except as otherwise indicated, area measurements are given in gross floor area. Restroom facilities and areas used for storage may be excluded from the floor area calculation.
Bedroom Calculation: Any separate room which meets the definition of bedroom, which could legally be used as a bedroom, regardless of whether such room is labeled as a den, study, office, or similar, shall be counted as a bedroom for the purposes of parking calculation. Rooms that meet the definition of a bedroom which are separated by a narrow corridor that could allow for the separation of the areas into individual bedrooms shall each be counted as a bedroom for the purposes of parking calculation.
Specific Zone Exemptions: The following zoning districts have off-street parking requirements specific to each respective zone and are not required to meet Section 4-6-5(E)(6) below; however, all other provisions of Section 4-6-5 shall apply.
- Central Business (CB) Zoning District: Off-street parking is not required within the CB Zoning District.
