A two-unit project must satisfy each of the following development standards and requirements:

B. Zone: The lot is in a single-family residential zone of the City of Redlands (R-1, R-1-D, R-S, R-A, R-A-A, R-E, R-R, or R-R-A zoning districts) or a single-family district within an adopted Specific Plan of the City.

C. Lot Location: The lot is not located on a site that meets any of the location criteria as listed in Government Code § 66411.7(a)(3)(C) (and incorporating Government Code section 65913.4(a)(6)(B) - (K) by reference).

D. Not Historic: The lot shall not be within a site that is designated or listed as a city landmark or historic property or historic/scenic district, and the lot shall not be a historic property or within a historic district that is listed on the State Historic Resources Inventory (as defined in Section 5020.1 of the Public Resources Code).

  1. Housing that is income-restricted for households of moderate, low, or very low income.

  2. Housing that is subject to any form of rent or price control through a public entity's valid exercise of its policy power.

  3. Housing that has been occupied by a tenant in the last three (3) years. The applicant and the owner of a property for which a two-unit development is sought must provide a sworn statement as to this fact with the application for the parcel map. The City may conduct its own inquiries and investigation to ascertain the veracity of the sworn statement, including but not limited to, surveying owners of nearby properties; and the City may require additional evidence of the applicant and owner as necessary to determine compliance with this requirement.

  • F. Dwelling Unit Standards:
  1. Quantity: For purposes of this section, "unit" means any dwelling unit, including, but not limited to, a primary dwelling unit, a unit created under this section of this code, an ADU, or a Junior ADU.

a. No more than two (2) dwelling units of any kind may be built on a lot that results from an urban lot split

b. A lot that is not created by an urban lot split may have a two-unit project under this section, plus any ADU or Junior ADU that must be allowed under State law and the City's ADU ordinance, not to exceed two (2) primary dwelling units per lot and a combined total of four (4) dwelling units within the development.

  1. Height Restriction: All dwelling units shall be subject to the same height limitations applicable to the underlying zone.

  2. Lot Coverage: The lot coverage limit shall be applicable within the zoning district where the subject property is located. This lot coverage standard is only enforced to the extent that it does not prevent the construction of two (2) primary dwelling units on the lot at eight hundred (800) square feet each.

  3. Open Space: The new development shall be subject to the open space requirement, if any, imposed within the zoning district where the subject property is located. This open space standard is only enforced to the extent that it does not prevent the construction of two (2) primary dwelling units on the lot at eight hundred (800) square feet each.

  4. Setbacks:

  • a. Generally: All setbacks must conform to those objective setbacks that are applicable to the underlying zone.

  • b. Exceptions: Notwithstanding subsection F1a above:

(1) Existing Structures: No setback is required for an existing legally established structure or for a new structure that is constructed in the same location and to the same dimensions as an existing legally established structure.

(2) Eight hundred (800) square-feet; four-foot (4') side and rear setbacks. Exceptions to the setbacks imposed by the underlying zone may be applied to the degree necessary to avoid physically precluding up to two (2) units on the lot or either of the two (2) units from being of at least eight hundred (800) square feet in floor area on the subject property; but in no event may any structure be less than four feet (4') from a side or rear property line.

and rear setbacks. Exceptions to the setbacks imposed by the underlying zone may be applied to the degree necessary to avoid physically precluding up to two (2) units on the lot or either of the two (2) units from being of at least eight hundred (800) square feet in floor area on the subject property; but in no event may any structure be less than four feet (4') from a side or rear property line.

(3) New Structures: Shared interior lot line; zero foot (0') interior side setback. Setback requirements for an interior side lot line, where the interior lot line is shared between the two (2) new parcels (and the lot line is perpendicular to the primary street frontage of both lots), may be modified to permit a zero foot (0') side setback. The intent of this provision is to permit a shared wall between two (2) new dwelling units on separate lots, so that the combined structure has the appearance from the street as one single-family residence. Designs with a shared common wall shall comply with all applicable California Building Code regulations, and the Director may require a Homeowners' Association as well as CC&Rs for the subject properties. If this provision for a zero foot (0') interior side setback is not utilized, then the standard setback requirement shall apply, and in no case shall be less than four feet (4').

  1. Parking: Each new primary dwelling unit shall have one (1) off-street parking space per unit on a paved surface, which may be covered or uncovered, placed outside of all required setbacks, and constructed in accordance with the applicable provisions of Article I of Chapter 18.164 of this title. Off-street parking shall not be required if one of the following applies:
  • a. The lot is located within one-half mile walking distance of either:

  • (1) A corridor with fixed route bus service with service intervals no longer than fifteen (15) minutes during peak commute hours; or

(2) A site that contains one of the following: an existing rail or bus rapid transit station; or the intersection of two (2) or more major bus routes with a frequency of service interval of fifteen (15) minutes or less during the morning and afternoon peak commute periods.

b. The site is located within one block of a car-share vehicle location that is permanently installed and permanently marked for car-share pickup or dropoff service.

  1. Nonconforming Conditions: A two (2) unit project may be approved without requiring a legal nonconforming zoning condition or standard

to be corrected. This provision shall supersede Chapter 18.184 of Title 18 of the Redlands Municipal Code for the duration that applicable State law remains in effect.

  1. Utilities: Each primary dwelling unit on the lot that is or that is proposed shall comply with the development regulations applicable to the underlying zone.

  2. Building And Safety: All structures built on the lot shall comply with all building code regulations applicable to the underlying zone.

G. Fire Hazard Mitigation Measures: For a development project on a lot that is located in a fire hazard severity zone (as defined by the California Department of Forestry and Fire Protection), the proposal shall comply with all applicable fire-hazard mitigation measures:

  1. The proposed development complies with the applicable provisions of the California Fire Code, and any amendments thereto adopted in the Redlands Municipal Code, that apply uniformly to development within the underlying zone.

  2. The proposed development complies with the applicable provisions of the California Building Code (including Chapter 7A), and any amendments or additions thereto adopted in the Redlands Municipal Code (including RMC Chapter 15.30 Wildland-Urban Interface Code), that apply uniformly to development within the underlying zone.

  3. The subject property will comply with all applicable landscape design, materials, fuel modification, and vegetation management requirements of applicable State law (including but not limited to Calif. Gov. Code § 51182, Public Resources Code § 4291, Calif. Fire Code § 4906, and Calif.

Code § 65589.5(d)(2): "a significant, quantifiable, direct, and unavoidable impact, based on objective, identified written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete" and does not include (1) inconsistency with the zoning ordinance or general plan land use designation or (2) the eligibility to claim a welfare exemption under Revenue & Taxation Code section 214(g).
