    Benefits of Building a Permitted ADU in San Jose

    When considering an ADU in San Jose, opting for a permitted construction offers multiple advantages. Here are the key benefits of building a legally permitted ADU:


    1. Legal Compliance and Peace of Mind

    A permitted ADU ensures that your construction complies with all local building codes and zoning laws. This prevents legal issues, fines, or costly revisions down the line, providing you with peace of mind throughout the project.


    2. Increase Property Value

    A permitted ADU can significantly increase your home’s value. Potential buyers will see the additional living space as an asset, particularly when it’s a legal, compliant unit. In a competitive market like San Jose, this can be a major selling point.


    3. Rental Income Opportunities

    If you’re looking to create a source of passive income, a permitted ADU is the way to go. With proper permits, you can legally rent out the space, whether it’s a long-term rental or short-term via platforms like Airbnb. An unpermitted unit, on the other hand, can lead to fines and legal issues, and may not qualify for rental purposes.


    4. Financing and Insurance Benefits

    Lenders are more likely to approve financing for a permitted ADU, and the unit is more likely to be covered by your home insurance policy. If the ADU is not permitted, it may affect your ability to secure a loan or insurance coverage, making the process much more complicated.


    5. Enhanced Livability and Functionality

    Permitted ADUs are designed to meet building codes and safety standards, ensuring a comfortable, functional, and secure living space. Whether it's for a family member or a tenant, you'll have a livable unit that is both safe and legally recognized.
