50.02.001 RESIDENTIAL DISTRICTS 1. RESIDENTIAL-LOW DENSITY ZONES

a.

Districts

The residential-low density zone districts are R-15, R-10, and R-7.5. b.

Purpose

To provide lands for single-family residential development with densities ranging from two to five dwelling units per gross acre.

(Ord. 2579, Repealed and Replaced, 03/20/2012) 2. RESIDENTIAL-MEDIUM DENSITY ZONES

a.

Districts

The residential-medium density zone districts are R-6, R-5, and R-DD. b.

Purpose i.

R-5

To provide lands for single- and multi-family residential development with densities ranging from seven to eight dwelling units per gross acre. ii.

R-DD Zone (1) The purpose of the R-DD zone is to assure that single-family homes are protected from noise, light, glare and reduction in privacy to the maximum extent possible during the areaâ&#x20AC;&#x2122;s transition to higher density residential use, to facilitate good architectural design and site planning which maintains residential choices of unit size, cost and other amenities and supports the economic feasibility of new construction and development, and to assure protection and compatibility of all land uses, including commercial, residential, park, open space and historic sites.

(2) The R-DD zone is intended for use in low density residential districts which are undergoing transition to increased densities, and which have scenic, historic, natural or residential features which should be preserved and integrated with new development.

iii.

R-6 Zone

The FAN R-6 zone is intended to implement the land use policies of the First Addition Neighborhood Plan. The purpose of this zone is to ensure the design quality of proposed development in the neighborhood by: (1) Ensuring that proposed building designs are visually compatible with the character of existing structures, maintain adequate light and air between structures, and complement the

The Lake Oswego Municipal Code is current through Ordinance 2772, and legislation passed through March 6, 2018.

Lake Oswego Municipal Code 50.03.001 INTRODUCTION TO THE USE TABLE

neighborhoodâ&#x20AC;&#x2122;s architectural character.

(2) Minimizing the visual impact of garages from the street, and to continue established alley uses and functions such as access to garages, off-street parking and trash removal.

(3) Encouraging compatible and sensitive remodeling and renovation of existing residences.

(4) Preserving the small-town character of the existing streetscape by allowing singlefamily development that is human scale and pedestrian oriented.

(5) Enhancing the natural environment of the neighborhood as one of the dominant characteristics.

(6) Preserving FANâ&#x20AC;&#x2122;s historical and architectural character by encouraging infill development that is compatible in design character to landmark structures on abutting lots.

(Ord. 2612-A, Amended, 05/21/2013; Ord. 2579, Repealed and Replaced, 03/20/2012) 3. RESIDENTIAL-HIGH DENSITY ZONES

a.

Districts

The residential-high density zone districts are R-3, R-2, R-0, and R-W. b.

Purpose

To provide lands for single- and multi-family residential development with densities of at least 12 dwelling units per gross acre.

(Ord. 2579, Repealed and Replaced, 03/20/2012) 50.03.001 INTRODUCTION TO THE USE TABLE 1. INTRODUCTION TO THE USE TABLE

Tables 50.03.002-1, Residential Districts Use Table, and 50.03.002-2, Commercial, Mixed Use, Industrial, and Special Purpose Districts Use Table, list land uses and indicate whether they are allowed by right or with a conditional use permit, or prohibited in each base zone district. The use table also includes references to any additional regulations applicable to that use.

(Ord. 2579, Repealed and Replaced, 03/20/2012) 1. HOW TO USE

a.

Permitted Uses

A "P" in a cell of a use table indicates that the land use is allowed by right in that base or overlay zone, subject to compliance with the use-specific standards referenced in the final column of the use table. Permitted uses are subject to all other applicable requirements of this Code, including those set forth in LOC 50.06, Development Standards. Uses accessory to a permitted use are allowed regardless of whether they are listed separately in the use table.

The Lake Oswego Municipal Code is current through Ordinance 2772, and legislation passed through March 6, 2018.

Lake Oswego Municipal Code 50.03.001 INTRODUCTION TO THE USE TABLE

b.

Page 3 of 34

Conditional Uses

A "C" in a cell of a use table indicates that the land use is allowed in that base or overlay zone only upon approval of a conditional use permit as described in LOC 50.07.005, Conditional Use Permits, including the specific conditions listed in LOC 50.07.005.3, and compliance with any use-specific standards referenced in the use table. Uses subject to a conditional use permit are subject to all other applicable requirements of this Code, including those set forth in LOC 50.06, Development Standards.

Uses accessory to a conditional use are allowed regardless of whether they are listed separately in the use table. c.

Accessory Uses

An "A" in a cell of a use table indicates that the land use is expressly allowed in that base or overlay zone as an accessory use to a permitted use or an approved conditional use. In addition to those expressly listed, all uses that are secondary and subordinate to a permitted or approved conditional use, and are frequently found in connection with that permitted or approved conditional use, are allowed as accessory uses. A use is "accessory," when the use is (i) generally accepted as accessory to a primary use based on state of the industry, (ii) the accessory use is secondary to the primary use, (iii) the impacts of the accessory use do not significantly alter the impacts of the primary use (e.g., traffic volume), and (iv) the accessory use is not the same size or scale as would be found for a primary use elsewhere. d.

Prohibited Uses

A blank cell in a use table indicates that the land use is prohibited in that base or overlay zone district. e.

Overlay Districts Provisions Govern

When a property is located within the boundaries of an overlay district, the use table provisions for that overlay district prevail over those in the base zone district. For example, if a use is prohibited in the base zone district where the property is located, but is a permitted use in an overlay district applicable to the same property, then the use is allowed on that property. On the other hand, if a use is listed as a permitted use in the base zone district but is listed as a conditional use in an overlay zone district applicable to the same property, then the use is a conditional use for that property.

Where a property is located in more than one overlay district, then the most restrictive use provision in those overlay zone districts shall apply to the property. f.

Use-Specific Standards and Table Notes

There may be additional standards that apply to specific permitted or conditional uses. Those additional standards are either identified in a note at the end of the table or cross-referenced under the â&#x20AC;&#x153;use specific standardsâ&#x20AC;? column in the use table. The cross-referenced standards appear in LOC 50.03.003, Use-Specific Standards, immediately following the use table. g.

Authorization for Similar Uses

The City Manager may authorize that a use not specifically named in the permitted, conditional or prohibited uses of a district be included among the allowed uses, if the use 1) is similar to and of the same general type as the uses specifically allowed; 2) is consistent with the Comprehensive Plan;

The Lake Oswego Municipal Code is current through Ordinance 2772, and legislation passed through March 6, 2018.

Lake Oswego Municipal Code 50.03.001 INTRODUCTION TO THE USE TABLE

Page 4 of 34

and 3) has similar intensity, density, off-site impacts and impacts on community facilities as uses permitted in the zone. However, the City Manager may not authorize a use already specifically permitted in any other zoning district. A person disagreeing with the City Managerâ&#x20AC;&#x2122;s decision may appeal that decision to the Planning Commission pursuant to LOC 50.07.003.7.b, Appeal of Minor Development Decision.
