This model combines UrbanSim data and external information to calculate the cost of housing experience by different household types (JUST QUARTILES?). It assumes the following external components work:

  • Explicit tenure
  • True housing prices and rents
  • Rent control
  • Explicit representation of deed restricted units in basemap and forecast years

Households are assigned to five situations:

  • Deed-restricted units: these households pay a set percentage of their income based on external data (around 27% of income, number from table). The count is determined by the number of HHs placed in deed-restricted units
  • Subsidized rent: these households also pay a set percentage of their income (around 27%, number from table). Their count is determined by a percentage of all households in the table (ie user defined)
  • Rent-controlled: these households pay an amount that reflects forecast market rents decreased by 1) any differential movement rate and 2) lower investment in rent controlled units (these adjustments are from a table). The count of these households is determined by counting HHs in units marked as rent controlled (from base map or policy)
  • Renters: these households pay an amount that reflects forecast market rents as computed through a cost model (provided through the table). There count is determined by HHs in non-rent-controlled rental units.
  • Owners: these households pay an amount that reflects forecast market prices as computed through a cost model (provided through the table). There count is determine by HHs in market rate ownership units.

Additions to UrbanSim

  • New table (housing_cost_controls.csv) with 5 year market stuff med/avg income for each quartile/segment
  • Housing Cost Model:
  1. count how many HHs of each type in each of the 5 situations
  2. calculate r
