¨ On a colloquial basis, these homes might be called: cottage homes, grouped dwellings, cluster development,
multi-dwelling lot, etc.  We’ll refer to them as “cluster” homes. 

¨ Your lot does not have to be subdivided. 

¨ Land ownership can be held in a variety of ways but generally speaking, common open space, the “cluster” feature,
is usually owned by an HOA. 

¨ For illustration calculation purposes, we are assuming that the house and any structures are scraped/bulldozed first.  (However, existing homes may be able to stay depending upon other parameters).

¨ Cluster homes do not have to face the street; they can face each other inside the lot.

¨ Limited to 1800 Gross Floor Area (GFA*) per house.  Houses may be 35’ high.

¨ One Accessory Dwelling Unit (ADU) allowed per lot. Maximum 1400 GFA. Maximum 20’ high unless over a garage then 30’ high.

¨ Must adhere to setbacks, distances between structures, and have 50% open space. (Required open space is currently more:  R-1-43 (65%), R-1-18, R-1-12 and R-1-9 (60%).  R-1-6 and R-2 are also 50%).

¨ Accessory structures (garages, barns, sheds, etc.) allowed; must adhere to above.

¨ Limited parking requirements.

¨ Lakewood homes in top left picture below are currently (3-1) listed for sale at $960,000. NOT affordable.

 About GFA from the new zoning ordinance:

Article 14: Definitions and interpretations, 17.14.2: Definitions: Floor Area, Gross (GFA): The area within the exterior façade of a building, including all covered and enclosed space on all floor levels of a building, halls, corridors, lobbies, mezzanines, display areas, stairways, elevator shafts, escalators, utility cores, air conditioning and heating areas, and common facilities for use of all tenants, except that gross floor area shall not include any open exterior plazas which are eligible for inclusion in covered open space, partially enclosed crosswalks, ramps, bridges, or other such buildings or structures intended for pedestrian use, loading areas, underground truck roads and service facilities. Where specified, GFA may be measured utilizing different methods for different purposes throughout this Zoning Code.

17.5.2: Residential Standards 17.5.2.1: Dimensional Standards: For the purposes of calculating residential gross floor area (GFA) in this section, below grade space shall not be included. Any level with an average of at least thirty (30) inches in height above grade along the street facing façade will be counted toward the overall structure GFA. Egress stairs added to an existing building are also excluded from GFA calculation in this Section. This definition may differ from square footage reported in real estate listings.

 Other Building Options (instead of Cluster Homes)

 ¨ 1 house, or 1 duplex or one 2-unit townhome per lot: entire structure limited to 4000 maximum GFA.

¨ 1 triplex, or 1 quadplex or one 3+ unit townhome per lot: entire structure limited to 5,000 maximum GFA.

¨ Your lot may be subdividable depending upon zoning (R-L-A, R-L-B or R-L-C), lot square footage and lot width (street frontage length) 

 How to calculate how many cluster homes could be built on your lot

  ¨ Look up your lot square footage: Jefferson County

 ¨ Look up your proposed zoning (R-L-A, R-L-B or R-L-C): Lakewood

 ¨ Take your lot square footage and subtract your lot minimum square footage 
      (R-L-A = 7,000; R-L-B = 5,000; R-L-C = 1,500).  This allots for Cluster Home #1. 

 ¨ Divide the result by 3000 (minimum square footage amount for each additional cluster home).

 ¨ Round down the result and this number represents the additional number of cluster homes which could be built. 

  ¨ Example:  Lot size 14,500 in R-L-B.  14,500-5,000 (1st home) = 9,500. 9,500 divided by 3,000 = 3.17. 
      Round down to 3 for home #2, #3 and #4.  This 14,500 square foot lot in R-L-B could have 4 cluster homes plus an ADU. 

  Zoning Code Amounts

 ¨ Zone                Minimum Size         Minimum Width

 ¨ R-L-A               7,000 sq. feet                 75 feet

 ¨ R-L-B               5,000 sq feet                  60 feet

 ¨ R-L-C               1,500  sq feet                 25 feet
