Foundation (engineering)
Foundations are designed to have an adequate load capacity depending on the type of subsoil/rock supporting the foundation by a geotechnical engineer, and the footing itself may be designed structurally by a structural engineer. The primary design concerns are settlement and bearing capacity. When considering settlement, total settlement and differential settlement is normally considered. Differential settlement is when one part of a foundation settles more than another part. This can cause problems to the structure which the foundation is supporting. Expansive clay soils can also cause problems.

Other requirements for HOME funds include the match of funds from other sources, minimum affordability terms for projects, limits on TBRA, and a time limit on when the funds must be allocated and spent by. For every dollar of HOME funds received, jurisdictions must provide a 25 cents match in non-federal sources. Newly constructed rental housing must remain affordable for at least 20 years. For owner-occupied housing (newly constructed and remodeled), acquired rental housing, and remodeled rental housing, the minimum affordability term ranges from 5 to 15 years depending on the amount of funds received in relation to the number of assisted units. Unlike Section 8 vouchers, TBRA is limited to two years and may not be used for project-based rental assistance. Finally, HOME funds must be committed (including reserving funds for CHDOs) within two years and be spent within five years.
