2.2 Trends in housing mix <br />Housing mix is the mixture of housing (structure) types (e.g., single- <br />family detached or apartments) within a city. State law requires a <br />determination of the future housing mix in the community and allows <br />that determination to be based on different periods: (1) the mix of housing <br />built in the past five years or since the most recent periodic review, <br />whichever time period is greater, (2) a shorter time period if the data will <br />provide more accurate and reliable information, or (3) a longer time <br />period if the data will provide more accurate and reliable information <br />(ORS 197.296). This section presents housing mix data for two periods (a) <br />housing mix over the 2001 to 2012 period and (b) housing mix further <br />back, including in 1990 and 2000. <br />There are several ways to look at change in housing mix over time, each of <br />which shows a slightly different mix of housing. Table 1 shows the mix of <br />housing building permits issued in Eugene between 2001 and 2012. Table <br />4 shows changes in housing mix observed through address and tax lot <br />data over the 2001 to 2012 period. Table 5 shows changes in the mix of <br />housing stock in Eugene reported in the census over the 1990 to 2011 <br />period. The information about housing mix for building permits issued <br />and for dwelling units built over the last few years(Table 2 and Table 4) <br />provide useful information about recent trends in housing mix, which <br />may be helpful in forecasting changes in housing mix. Longer-term <br />information about the mix of the City's entire housing stock (Table 5) also <br />provides useful information for forecasting changes in housing mix. <br />Table 4 shows the observed housing mix for residential development over <br />the 2001 to 2012 period. ECO selected this time period over the 2001 to <br />2012 period because it shows housing mix that occurred since the City's <br />revised zoning ordinance went into effect in 2001. <br />About 63% of housing developed between 2001 and 2012 was single- <br />family detached (including manufactured homes), 9% was single-family <br />attached, and the remaining 28% were structures with two or more units. <br />Table 4.
