HOUSING CONSTRAINTS <br />Residential Development Standards <br />The Transit Zoning Code provides a range of residential development standards <br />that are based on building type. The TZC envisions up to 13 building types, of <br />which 10 permit multiple - family housing. Densities range from 5 units per acre <br />for a single - family house to 90 units per acre for tower -on- podium products. The <br />wide range of densities and building heights permitted in the proposed plan <br />would greatly facilitate housing production for a wide range of family types and <br />household incomes. <br />Summarized in Table B -10, the development standards facilitate the development <br />of building types that are affordable to a range of income levels. The proposed <br />parking requirements, 2 tenant spaces plus 0.15 -0.25 guest spaces per unit, reflect <br />the transit - oriented nature of the area. The TZC proposes modest minimum and <br />maximum setbacks (0 -15 feet), depending upon the development zone, to <br />promote a more active street front. The open space requirements are flexible, <br />reflect the urban feel of the area, and facilitate the most efficient and cost - effective <br />use of developable area. <br />Table B -10 <br />Residential Development Standards in the <br />Transit Zoning Code <br />Building Type <br />Multiple- <br />Family <br />Density <br />Range' <br />Lot Width <br />Max <br />Stories <br />Open Space3 <br />Tower on Podium <br />Yes <br />75 -90 <br />200' -250' <br />25 <br />20% <br />Commercial Block <br />Yes <br />30 -40 <br />75' -200' <br />10 <br />15% <br />Liner <br />Yes <br />45 -50 <br />125' -200' <br />5 <br />225 SF /bldg <br />Stacked Dwelling <br />Yes <br />40 -50 <br />125' -200' <br />6 <br />15% <br />Hybrid Court <br />Yes <br />45 -50 <br />150' -200' <br />5 <br />15% <br />Courtyard Housing <br />Yes <br />20 -30 <br />125' -200' <br />5 <br />15% <br />Live -Work <br />No <br />12 -15 <br />75' -125' <br />3 <br />15% <br />Rowhouse <br />Yes <br />7 -18 <br />75' -150' <br />3 <br />15% <br />Tuck -Under Housing <br />Yes <br />12 -18 <br />66' -250' <br />3 <br />250 SF /unit <br />Bungalow Court <br />Yes <br />10 -15 <br />100' -180' <br />2 <br />15% <br />Duplex/Triplex/Quad <br />Yes <br />10 -15 <br />50' -75' <br />3 <br />150 SF/ unit' <br />House <br />No <br />5 -7 <br />40' -60' <br />2 <br />100 SF + 15 %5 <br />Source: Transit Zoning Code, June 2010 <br />Notes: <br />1. Density ranges represent the limits of each building type and the dwellings it can accommodate per acre. <br />2. The first number is the minimum lot width and the second number is the maximum lot width. <br />3. Unless otherwise noted, the amount of open space required is calculated as a percentage of the lot area. <br />4. Each ground floor unit shall have a yard of at least 150 square feet. Aboveground floor units are exempt. <br />5. Homes are required to have one side yard of 10x10 feet and a rear yard calculated as 15 percent of lot area. <br />J�A <br />B -24 CITY OF SANTA ANA GENERAL PLAN HOUSING ELEMENT <br />
