If you’re considering adding a granny flat to your property in San Jose, one of the first questions that may come to mind is: how much will it cost? While there’s no one-size-fits-all answer, as each project is unique, several factors can affect the cost of building a granny flat in San Jose.
Building a San Jose granny flat can vary significantly depending on the size, construction type, site preparation, permits, and labor expenses. A typical granny flat costs $159,000 to $470,000 to construct. Larger units, custom-built structures, extensive site preparation, and high labor costs can contribute to the higher end of this range.
In this guide, we’ll explore these factors and provide an average cost estimate, tips on how to save money, and information about available financing options.
Granny flats, also known as accessory dwelling units (ADUs), are becoming increasingly popular in San Jose to add housing units to existing properties. Granny flats can be used as a rental unit, a home office, or a space for extended family members.
The cost of building a granny flat in San Jose can vary depending on several factors, including:
The size of a granny flat is a significant determinant of its construction cost in San Jose. Smaller flats are typically less expensive to construct than larger ones due to the lesser materials and labor required. The average granny flat size in San Jose is around 400 square feet. Building such a space generally costs between $50 to $100 per square foot, making size an essential factor to consider in budgeting.
The construction type significantly influences the cost of building a granny flat. Prefab or prefabricated granny flats, typically manufactured off-site and then transported for installation on the property, are generally less expensive than site-built granny flats constructed from scratch on the property itself. Consequently, the costs differ for each type: prefab granny flats typically range from $100 to $150 per square foot, while site-built granny flats can cost between $150 to $200 per square foot.
The quality of materials and finishes used in constructing a granny flat also significantly impacts the overall cost. Using higher-quality materials and finishes naturally incurs a higher expense than opting for lower-quality alternatives. For instance, standard materials and finishes typically range from $10,000 to $20,000. However, if one upgrades to superior materials and finishes, the cost can be between $20,000 and $30,000. Thus, the choice of fabrics and finishes plays a crucial role in determining the final cost of the granny flat.
According to the City of San Jose, building permit fees are calculated based on the valuation of the project, which includes the cost of materials and labor. These costs can fluctuate based on the size and complexity of the project. However, generally, one can anticipate an expense ranging from $2,000 to $5,000 on permits and inspections. Therefore, it’s essential to account for these regulatory costs during the budgeting process for the granny flat construction.
The cost of site preparation for a granny flat construction is another variable that depends mainly on the property’s condition. The site preparation costs will likely be minimal if the property is level and free from significant obstacles. However, if the property is uneven or contains obstructions like trees that need to be removed, the site preparation costs can significantly increase. Consequently, depending on these factors, the site preparation cost should range from $1,000 to $5,000. It’s crucial to assess the property’s condition beforehand to avoid unexpected costs during construction.
Labor cost is another significant component in the total expense of constructing a granny flat. The cost of labor can fluctuate based on factors such as the complexity of the project and the local availability of labor. However, as a general guide, one can anticipate labor costs to fall between $20,000 and $40,000. Therefore, while planning the construction of a granny flat, it’s essential to factor in these potential labor expenses to ensure a realistic budget is set.

Several strategies for saving money when building a granny flat in San Jose without compromising quality.
Exploring various financing options is practical when building San Jose granny flats. These options ease the financial burden by dividing the total cost into manageable payments.
Construction loans are specifically designed to finance construction projects. They offer a unique advantage by allowing borrowers to access funds in stages as the project progresses. This means you can borrow money as needed, ensuring the necessary funds are available at each phase of the construction process.
If you have a good credit score, personal loans can be an affordable and convenient option for financing your granny flat project. With a personal loan, you can access the funds you need to make your vision a reality, whether for constructing, renovating, or expanding your granny flat.
These loans allow you to use the equity in your home as collateral for obtaining a loan specifically designed to fund the construction of a granny flat. Because they have lower interest rates than other financing options, it has become famous for homeowners to finance granny flat projects this way.
These loans allow homeowners to access funds by leveraging the value of their property. With a HELOC, you can borrow money as needed, up to a predetermined limit, and only pay interest on the amount you borrow. This flexible borrowing option allows you to tap into your home’s equity for various purposes, such as home improvements, debt consolidation, or unexpected expenses.
Depending on your location and income level, government programs may offer financial assistance and incentives for homeowners looking to build a granny flat on their property.
