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.
PACE financing
For consumers, PACE type programs have several problems. Because the financing is designed to stay with the property, eligibility is based primarily on property information rather than income and FICO scores. A homeowner’s ability to pay is currently based primarily on their mortgage and property tax payment history as well as the requirement that there are no recent bankruptcies. Most significantly, homeowners are financed for the home improvements without any assessment of whether the financing is affordable for the homeowner, though Senate Bill 242, currently being considered in California, would require PACE providers to conduct an income review. Because the PACE financing is structured as a tax assessment instead of a loan, the PACE programs historically have not had to provide to homeowners the same disclosures about the financing costs that traditional lenders must provide. In September 2016, California Governor Jerry Brown signed AB2693 into law, which required PACE programs to provide mortgage-level disclosures and some providers to conduct live recorded calls with the homeowner to confirm financing terms and obligation. In some cases, without either an assessment of affordability or these disclosures about the costs of the financing, homeowners depend on what the PACE program providers tell them when trying to figure out whether the financing is affordable. Homeowners have complained that PACE contractors are lying about the costs of financing as part of selling the program. These problems create a situation in which homeowners can suddenly owe far more in property taxes than they can afford to repay; this is especially true for retired and disabled homeowners on fixed incomes. PACE architects Cisco DeVries and Matthew Brown deny these claims as "isolated incidents."
