Small Homes, Big Impact

Building homes that more of our neighbors can afford is essential to all who live and work in our communities

The greater Bay Area is growing, but there simply aren’t enough homes for everyone. When homeowners add rental homes on their properties, we add viable housing options for people seeking to remain in our communities. This is where homeowners who feel powerless to take action against their friends, relatives and neighbors being pushed out can take action to help.

We believe Bay Area homeowners can help solve the housing crisis by building homes to rent in their own backyards. Small Homes, Big Impact offers educational workshops and financial assistance to homeowners wishing to build an accessory dwelling unit (ADU).

How it Helps

Changes to California state law made it easier to build ADUs – also known as granny flats, in-law units or backyard cottages. Housing Trust’s Construction Loan pilot program bridges the gap between conventional financing options (such as a cash-out refinance, HELOC, borrowing from a retirement account, etc.) and the lack of secondary mortgage construction financing options.

The Housing Trust Construction loan program serves homeowners in Santa Clara County and the City of East Palo Alto. It consists of a three-year construction loan made as a second mortgage for a 36-month term for up to $200,000 to help cover hard construction costs.

Loan Terms

  • Maximum Loan Amount: Up to $200,000 or 97% of the property’s combined loan to value, whichever is lower
  • Eligible costs: Hard construction costs are eligible
  • Collateral: Second Mortgage / Deed of Trust
  • Maturity: 36-month term / 20-year amortization
  • Monthly Payments: Interest-only payments in 1st year, interest and principal payments in years 2-3 (first year of interest-only payments will be held back in escrow)
  • Must work with a Qualified Builder per Housing Trust requirements
  • Tenant income restriction up to 120% of Area Median Income. Borrower must lease the ADU at an affordable rate. Rent caps will be determined by the size of the ADU and will be updated annually.
