The cost comparison between adding an addition to your main house versus building a detached Accessory Dwelling Unit (ADU) depends heavily on your specific project. Generally, a simple bump-out addition can be less expensive per square foot as it leverages existing walls and utilities. However, a detached ADU, while potentially having higher initial costs for new foundations and separate utility connections, often adds more property value and offers greater rental income potential. It also avoids the disruption of living in a construction zone. Key factors include your lot's layout, local zoning, and the complexity of tying into existing home systems. For a detailed breakdown of costs, benefits, and regulations, see our internal resource All You Need to Know When Building Accessory Dwelling Units.
The $40,000 grant in California typically refers to the CalHFA ADU Grant Program. This initiative provides forgivable loans of up to $40,000 to qualified homeowners to cover pre-development costs associated with constructing an Accessory Dwelling Unit (ADU) or Junior ADU (JADU) on their property. Eligible costs include impact fees, planning, design, soil tests, and permit applications. The loan is forgiven if the ADU construction is completed and the unit is occupied by a low- or moderate-income tenant for a minimum of five years. This program aims to increase affordable housing stock and assist homeowners with the often-prohibitive upfront costs of ADU development. It is a key tool for addressing the state's housing crisis.
The cost to build a 1-bedroom ADU in San Diego typically ranges from $150,000 to $350,000, with significant variation based on size, design, and site conditions. Key cost drivers include foundation work, utility connections, permitting fees, and material choices. A detached new construction ADU generally costs more than converting an existing garage. It is crucial to budget for soft costs like architectural plans, engineering, and city permits, which can add 15-25% to the total. For a detailed breakdown of costs, timelines, and the benefits of adding an ADU to your property, we recommend reading our internal article Room Addition / ADU (JADU) Construction in San Diego. Professional consultation is essential for an accurate estimate tailored to your specific lot and goals.
The cost comparison between building an ADU (Accessory Dwelling Unit) and buying a prefab unit is nuanced. Generally, prefabricated ADUs can offer lower initial costs and faster installation due to controlled factory construction, potentially reducing labor expenses and construction loan durations. However, a custom site-built ADU, while often more expensive upfront, may provide better long-term value through higher-quality materials, perfect site integration, and customization that increases property value. Key factors include local permit costs, site preparation needs (like foundation and utility connections), and finish levels. A prefab might seem cheaper initially, but total costs can converge when factoring in site work, delivery, and crane fees. Professional consultation is crucial for an accurate project-specific estimate.
