Converting a garage into an Accessory Dwelling Unit (ADU) can be a valuable investment, depending on costs, potential rental income, and property value impact. Benefits include increased property value, steady rental income, and versatile use for housing, office space, or rentals.

Hire Professionals Engage an architect or design-build contractor for detailed plans and permit approval. Assess the structural integrity of the garage for necessary upgrades. Utilities Installation Plan and install electricity, plumbing, and HVAC systems. Construction Frame new walls and insulate. Install flooring, windows, and doors.

The cost of a garage conversion varies based on size and key influencing factors:
Size (sq ft) | Average All-In Price* | Key Influencing Factors |
---|---|---|
300 | $120,000 - $175,000 | Fixed costs such as design permits; high-quality, multifunctional solutions needed for smaller space |
500 | $180,000 - $250,000 | Economies of scale reduce per sq ft cost; choice of finishes and complexity of design play roles |
800 | $250,000 - $350,000 | Larger footprint allows standard construction methods; potentially lower costs for additional square footage |
1000 | $330,000 - $465,000 | Costs vary based on location, materials, and labor; similar to a small home |
1200 | $415,000 - $580,000 | Maximum potential for design complexity and high-quality finishes, impacting total cost |
Converting a garage into an ADU generally adds significant value to a house by increasing property value and generating rental income. The value increase can be up to 35%, depending on the size and type of ADU, build quality, and local housing market conditions. Detached ADUs typically add more value than attached or interior conversions. High-quality materials and unique features further enhance value. Rental income from an ADU can offset conversion costs, potentially yielding substantial financial returns over time. However, conversion costs range from $80,000 to $250,000, including permits and compliance with local regulations. Despite these costs, the long-term financial benefits often justify the investment.
Converting a garage into an ADU typically takes 8 to 12 months, broken down into the following phases:
Design Phase: 1-2 months to plan and finalize the ADU design. Permitting Phase: 3-4 months to obtain necessary permits and ensure compliance with local regulations. Construction Phase: 4-6 months to build and complete the conversion, depending on site conditions and project complexity.Yes, you can convert a garage into a living space. To do this cost-effectively, start by cleaning and sealing the floor, using high-quality paint or epoxy coating, or installing interlocking floor tiles. For the walls, consider painting, installing drywall, or waterproofing if needed. Insulate and finish the ceiling with drywall or wood panels. Use portable heating and cooling units or mini-split systems for climate control. Add windows for natural light and ventilation, and cover the garage door with a curtain if it's no longer used. For utilities, minimize costs by using existing lines, and perform DIY tasks where possible, leaving specialized work to professionals. Obtain necessary permits, use budget-friendly materials, and reuse existing items to keep costs low.
Converting half of a garage into a room involves several steps: determine the purpose of the new room, check local zoning laws and obtain necessary permits, establish a budget, and design the layout by dividing the garage space with an insulated wall. Ensure proper access, adequate windows, and ventilation. During construction, frame the new wall, insulate, install flooring, windows, and doors, and complete interior finishes such as drywall, painting, electrical wiring, plumbing, and HVAC installation. Finally, comply with building codes, address parking requirements, and furnish the new room according to its intended use.
The cost of obtaining a permit for a garage conversion in San Diego ranges from $6,000 to $12,000, depending on the project's complexity. This includes building permits ($3,000 to $4,000), additional permits for electrical ($200 to $2,000) and plumbing ($100 to $500), city fees ($3,000 to $5,000), and design and engineering fees (approximately $8,000). Miscellaneous expenses should also be considered, making up around 5-10% of the budget.
