Our operations are subject to continuing compliance requirements mandated by applicable federal, state and local statutes, ordinances, rules and regulations, including zoning and land use ordinances, building, plumbing and electrical codes, contractors' licensing laws, state insurance laws, federal and state human resources laws and regulations, and health and safety laws and regulations. Various localities in which we operate have imposed (or may impose in the future) fees on developers to fund schools, road improvements and low and moderate-income housing.
Availability of and costs related to permit, water/sewer tap, and impact fees can impact our homebuilding operations. From time to time, various municipalities in which our homebuilding subsidiaries operate restrict or place moratoria on the availability of utilities, including water and sewer taps. Additionally, certain jurisdictions in which our homebuilding subsidiaries operate have proposed or enacted "slow growth" or "no growth" initiatives and other measures that may restrict the number of building permits available in any given year. These initiatives or other similar measures could reduce our ability to open new subdivisions and build and sell homes in the affected markets. The availability issues previously discussed and any increases in costs of these fees may negatively impact our financial position, results of operations and cash flows.
Our homebuilding operations also are affected by regulations pertaining to availability of water, municipal sewage treatment capacity, land use, dust controls, oil and gas operations, building materials, population density and preservation of endangered species, natural terrain and vegetation.
We are subject to growing local, state and federal statutes, ordinances, rules and regulations concerning the protection of public health and the environment. These include regulating the emission or discharge of materials into the environment such as greenhouse gas emissions, storm water runoff, the handling, use, storage and disposal of hazardous substances, and impacts to wetlands and other sensitive environments. These restrictions and requirements could increase our operating costs and require additional capital investment, which could negatively impact our financial position, results of operations and cash flows. Further, we have extensive operations in the western United States, where some of the most extensive environmental laws and building construction standards in the country have been enacted. We believe we are in compliance in all material respects with existing governmental environment restrictions, standards and regulations applicable to our business, and such compliance has not had a material impact on our business. Given the emerging and rapid changes of environmental laws and other matters that may arise that are not currently known, we cannot predict our future exposure, and our future costs to achieve compliance or remedy potential violations could be significant.
The particular environmental laws and regulations that apply to any given homebuilding project vary greatly according to a particular site's location, the site's environmental conditions and the present and former uses. These environmental laws may result in project delays, cause us to incur substantial compliance and other costs and/or prohibit or severely restrict homebuilding activity in certain environmentally sensitive locations. Environmental laws and regulations may also have a negative impact on the availability and price of certain raw materials, such as lumber.
Our revolving credit facility contains representations regarding anti-corruption and sanctions laws, a violation of which could result in an event of default.
We also are subject to rules and regulations with respect to originating, processing, selling and servicing mortgage loans, which, among other things: prohibit discrimination and establish underwriting guidelines; provide for audits and inspections; require appraisals and/or credit reports on prospective borrowers and disclosure of certain information concerning credit and settlement costs; establish maximum loan amounts; prohibit predatory lending practices; and regulate the referral of business to affiliated entities.
The regulatory environment for mortgage lending is complex and ever changing and has led to an increase in the number of audits and examinations in the industry. These examinations can include consumer lending practices, sales of mortgages to financial institutions and other investors and the practices in the financial services segments of homebuilding companies. New rules and regulations or revised interpretations of existing rules and regulations applicable to our mortgage lending operations could result in more stringent compliance standards, which may substantially increase costs of compliance.
