Impact Housing is focused on alleviating the effects of Southern Californias housing crisis by developing socially responsible multifamily developments. While most Southern California developers are focused on building either luxury housing or subsidized affordable housing, Impact Housing delivers new unsubsidized housing that targets rent levels affordable to low- and moderate-income households – the most underserved segment of the population. Impact Housings business plan centers around our groundbreaking, multidisciplinary approach. Our vertically integrated services model coordinates under the same company the roles of "developer, "design-builder," and "property manager" to dramatically lower the cost of delivering new multifamily housing, thus enabling us to offer new housing at rents and in locations that are otherwise unachievable.
