ATTACHMENT3 <br />Overcrowding <br />A household is considered overcrowded if there is more than one person per room and severely <br />overcrowded if there is more than 1.5 persons per room. HUD CHAS data based on the 2016- <br />2020 ACS and the HCD AFFH Data Viewer (2017-2021 ACS) are used to show overcrowding in <br />Santa Ana and Orange County. <br />Regional Trend <br />As shown in Table 17, 2.7 percent of owner -occupied households and 9.5 percent of renter - <br />occupied households in the county are overcrowded. Severe overcrowding is slightly less of an <br />issue in the county. Approximately 1 percent of owner households and 6.1 percent of renter <br />households are severely overcrowded. <br />Table 17 <br />Overcrowdingb Tenure <br />Overcrowded <br />(>1 person per room) <br />Severely Overcrowded <br />(>1.5 persons per <br />room) <br />Total <br />Households <br />Households <br />Percent <br />Households <br />Percent <br />Santa Ana <br />Owner -Occupied <br />3,860 <br />10.60% <br />2,085 <br />5.70% <br />36,590 <br />Renter -Occupied <br />8,640 <br />20.00% <br />7,555 <br />17.80% <br />42,550 <br />Orange County <br />Owner -Occupied <br />16,150 <br />2.70% <br />6,520 <br />1.10% <br />595,230 <br />Renter -Occupied <br />42,145 <br />9.50% <br />27,060 <br />6.10% <br />444,775 <br />Source: HUD CHAS Data (based on 2016-2020 ACS), 2023 <br />Figure 67 shows concentrations of overcrowded households by tract regionally. Overcrowded <br />households are most concentrated in the central county areas, including the cities of Santa Ana, <br />Garden Grove, Westminster, Anaheim, and Stanton. Additionally, there are some dispersed tracts <br />with high percentages of households experiencing overcrowding in Costa Mesa. Areas northeast, <br />south, and west of Santa Ana have concentrations of overcrowded households below the State <br />average. <br />Local Trend <br />As presented in Table 17, a larger share of households in Santa Ana are overcrowded compared <br />to the countywide average. Nearly 17 percent of owner -occupied households and 38 percent of <br />renter -occupied households in the city have more than one person per room, which is significantly <br />higher than surrounding areas in the county. Moreover, 5.7 percent of owner households and 17.8 <br />percent of renter households are severely overcrowded, with more than 1.5 persons per room. <br />Figure 68 and Figure 69 show overcrowding by tract in the city. A majority of tracts have 20 or <br />more percent of households experiencing overcrowding. The northeast part of the city has census <br />tracts with slightly less overcrowding. Overall, there are six census tracts in the city with <br />percentages of overcrowded households at or below 5 percent, these are located in the northeast <br />and to the south in the South Coast Metro area. The South Coast Metro area, in particular, <br />features more recently developed housing, including larger single-family homes, townhomes, and <br />Ordinance No. NS-3075 <br />
