How Much Does It Cost to Convert Your Garage into a Unit or an ADU in San Francisco?
Converting a garage into a unit or an ADU in San Francisco can be a great way to add living space, but it can also be expensive and complex. The challenge lies in understanding the costs involved to make informed decisions and budget effectively. The typical costs associated with garage conversions in San Francisco include construction, permits, and design. Understanding these expenses helps you manage your budget effectively and make the most of your project.
Initial Investment and Budgeting
Converting a garage into an Accessory Dwelling Unit (ADU) in San Francisco requires a significant investment, typically between $60,000 and $130,000, covering both labor and materials. This initial expense should be balanced with the potential long-term benefits of added living space.
Professional Services
Beyond construction costs, it's important to factor in professional services from architects and engineers, which usually account for about 10% of the total construction costs.
City Fees and Permitting
City fees for permits and compliance add another 6 to 9% to your total costs. The exact amount varies based on your lot and the specifics of your project. Seismic upgrades, variances, or additional permits can increase both the time and cost of your project.
Contingency Fund
To prepare for unexpected expenses, it's wise to set aside a contingency fund, typically 5% to 10% of the total project budget. This fund helps cover unforeseen costs or changes that may come up during construction.
Factors Affecting Cost
Several factors can influence the cost of converting a garage into an ADU. Understanding these factors helps homeowners better estimate potential expenses and challenges.
Size and Condition of the Existing Garage
The size and condition of the existing garage are key factors in determining the conversion cost. Larger garages typically need more materials and labor, while garages in poor condition may require extensive repairs or structural work before conversion starts. Evaluating the existing structure and identifying necessary repairs is crucial for accurate cost estimation.
Complexity of the Conversion
The complexity of the conversion impacts overall costs. For example, adding plumbing for a bathroom or kitchen increases both material and labor costs. Structural changes, like removing load-bearing walls or reinforcing the foundation, also add to the expense. Homeowners should carefully consider the features and amenities they want for their ADU and budget for any additional complexities.
Local Building Codes and Zoning Regulations
Following local building codes and zoning regulations is essential. These rules may specify minimum requirements for ceiling height, windows, insulation, and other aspects of the ADU. Non-compliance can lead to delays, so homeowners need to understand local regulations and budget for any necessary adjustments to meet code standards.

Return on Investment
Increased Property Value
Adding an Accessory Dwelling Unit (ADU) can greatly boost your property's value. Homes with extra units are in high demand, especially in San Francisco. An ADU can enhance your home's appearance and make it more attractive to buyers. Properties with ADUs often sell for more, providing a significant return on investment when it's time to sell.
Rental Income Potential
Converting a garage into an ADU can create a new source of rental income. Renting out the ADU can help cover the costs of the conversion and potentially generate profit over time. Rental income varies based on location, size, and local market conditions. In San Francisco, a garage ADU can potentially bring in around $42,000 per year. Homeowners should check local rental rates to estimate how much income their ADU could generate.
