RESIDENTIAL ZONES AND STANDARDS
(A) Rural Residential (RR) Zone: The RR land use designation is the least intense residential designation in the city, and is intended to guide development away from unsuitable areas, to preserve ecologically sensitive and important recreation areas. This zone allows for the development of single-family homes on significant acreage at a maximum density of one dwelling unit per ten (10) acres.
(B) Residential, Estate (RE) Zone: The RE land use designation permits the development of large lot, single-family residential areas, and is intended to provide for a rural setting and encourage preservation of open space and recreation areas. This zone allows a maximum density of one dwelling unit per five (5) acres.
(C) Residential, One Dwelling Unit Per Acre (R1) Zone: The R1 land use designation permits the development of large lot single-family residential areas and is intended to allow larger lot residential subdivisions. The zone allows a maximum density of one dwelling unit per acre.
(D) Residential, Four Dwelling Units Per Acre (R4) Zone: The R4 land use designation permits the development of low-density single-family residential neighborhoods. These neighborhoods would consist of larger home sites. The zone allows a maximum density of four (4) dwelling units per acre.
(E) Residential, Eight Dwelling Units Per Acre (R8) Zone: The R8 land use designation permits the development of medium density single-family housing and is intended to maintain traditional residential neighborhoods. The zone allows a maximum density of eight (8) dwelling units per acre.
(F) Residential, Sixteen Dwelling Units Per Acre (R16) Zone: The R16 land use designation permits the development of neighborhoods with multiple-family dwelling units and is intended to encourage a variety of housing opportunities. The zone allows a maximum density of sixteen (16) dwelling units per acre. (Ord. 821, 2-23-2006, eff. 3-16-2006)

Notes:
1.Measured at the setback line; for flag lots, the setback starts at the end of the pole section.
2.See section 3.10.08 of this title, regarding development standards.
3.See figure 3.3.04 of this chapter to determine minimum setbacks and section 3.3.041 of this chapter regarding snow shedding roof setback. However, no building element shall be closer to a side property line than 1/2 the building element height (see chapter 2, "Definitions", of this title); use the greater of this measurement or that determined from section 3.3.04 and figure 3.3.04 of this chapter.
4.If vehicle access is restricted on such street, a setback of 15 feet is permitted.
5.A conditional use permit may be applied for requesting a reduced setback, taking into consideration the surrounding zones, terrain, watercourse features, wetlands, or need for snow storage.
6.Exception to height allowances as noted in chapter 7, "Special Districts", of this title. All buildings over 35 feet in height will require a conditional use permit. 50 percent of the units gained by the additional height, if permitted, shall be community housing units.
7.To points of building elements in opposition.
8.Determine rear setback using section 3.3.05 of this chapter.
9.For zero lot line developments, the maximum lot coverage standard shall be increased by 10 percent for each lot line with a 0 foot setback. For example, for a lot with 1 zero lot line and a size of 10,000 square feet, the percent of lot coverage would be: 30% + 10% x (30%) = (30+3)% = 33%.

Home sites less than 50 feet wide | 5 foot minimum either side |
Home sites 100 feet wide | 10 foot minimum either side |
Home sites equal to or greater than 125 feet wide | 15 foot minimum either side |
Setback standard: | ||
Lots less than 100 feet deep | 5 foot minimum | |
Lots 100 - 200 feet deep | 10 foot minimum | |
Lots over 200 feet deep | 20 foot minimum |
Building/house footprint | 100 percent of footprint area = A | |
Decks, patios, walkways, plazas, etc. | 50 percent of covered area = B | |
Driveways, surface parking, etc. | 35 percent of covered area = C | |
Total = A+B+C |
Home sites equal to or less than 5,000 square feet | 50 percent | |
Home sites of 8,000 square feet | 33 percent | |
Home sites of 10,000 square feet | 30 percent | |
Home sites of 20,000 square feet | 24 percent | |
Home sites of 90,000 square feet | 15 percent | |
Home sites of 200,000 square feet and above | 10 percent |
(A) Lot Size = 7,000 square feet.
House plus garage footprint = 1,800 square feet x 1.00 = 1,800 (A).
Patio = 200 square feet x 0.50 = 100 (B).
Driveway and walk = 300 square feet x 0.35 = 105 (C).
A + B + C = 1,800 + 100 + 105 = 2005.
Lot size = 7,000; from figure 3.3.06, maximum value for A + B + C = 36%, or 2,520.
So this example meets the coverage requirement.
(B) Lot Size = 15,000 square feet.
House plus garage footprint = 3,500 square feet x 1.00 = 3,500 (A).
Patio and deck = 800 square feet x 0.50 = 400 (B).
Driveway and walk = 600 square feet x 0.35 = 210 (C).
A + B + C = 3,500 + 400 + 210 = 4,110.
Lot size = 15,000; from figure 3.3.06, maximum value for A + B + C = 26%, or 3,900.
So in example, something will have to be reduced to bring the total to 3,900.

(A) Landscaping. See section 3.8.13 of this title.
(B) Accessory dwelling units may be rented by obtaining approval per section 3.13.036 of this title.
(C) The commission may approve smaller individual lots in a multiple lot subdivision if the average size meets the minimum size values shown in table 3.3.03 in this chapter. See also chapter 10, "Planned Unit Development", of this title.
(D) Home occupation (see definitions, chapter 2 of this title). An occupation which complies with the following criteria shall be deemed a home occupation:
1. The use, including all storage space, shall occupy not more than fifty percent (50%) of the residence's floor area which is finished for living purposes.
2. There shall be no commercial advertising, except one nonluminous sign bearing the name and occupation of the resident, not exceeding two (2) square feet in area, and placed flat against the building.
3. No materials or mechanical equipment shall be used which will be detrimental to the residential use of said residence or surrounding residences because of vibration, noise, dust, smoke, odor, interference with radio or television reception, or other factors.
4. Materials or commodities delivered to or from the residence which are of such bulk and quantity as to require delivery by a commercial motor vehicle or a trailer, or the parking of customer's automobiles in a manner or frequency causing disturbance or inconvenience to nearby residents or so as to necessitate a parking lot, shall be prima facie evidence that the occupation is a primary business, and not a home occupation. "Commercial motor vehicle", for these purposes, shall not be said to include a united parcel service or federal express delivery or other like courier services and parcel post services, making deliveries to the subject property with a frequency not uncommon in residential neighborhoods.
