Understanding ADUs and Their Benefits

Accessory dwelling units (ADUs) are secondary housing units on a single-family residential lot. These units can serve various purposes, such as rental income, guest housing, or additional living space for family members. In Evergreen, San Jose, ADUs are becoming increasingly popular due to their flexibility and potential for adding property value.

  2. Rental Income: ADUs can provide a steady stream of rental income, making them a smart investment.
  3. Flexible Living Arrangements: Whether you need space for aging parents, college-aged children, or guests, an ADU offers versatile housing solutions.

Local Regulations and Zoning Laws

Before you start planning your ADU, it's crucial to understand the local regulations and zoning laws in Evergreen, San Jose.

Zoning Requirements

San Jose has specific zoning laws that govern where and how ADUs can be built. Before starting your project, check your property's zoning to ensure ADUs are allowed.

Size and Setback Restrictions

The size of your ADU and its placement on your property will be subject to city regulations. These rules often depend on your lot size and existing structures.

Permitting Process

Obtaining the necessary permits is critical. San Jose has streamlined the ADU permitting process, but you must submit complete and accurate documentation.

Planning and Designing Your ADU

Planning and designing your ADU requires careful thought and consideration.

Budgeting and Financing Options

ADU costs can range from $80,000 to $250,000, depending on size, type, and existing utilities. Some homeowners may qualify for the CalHFA ADU Grant, which can provide up to $40,000 towards construction costs. Home Equity Lines of Credit (HELOC) are also a popular financing option.

Choosing a Design

When planning your ADU, consider how the space will be used. Design choices should reflect the needs of potential occupants and complement the main residence. Hiring an experienced builder familiar with San Jose's regulations can ensure your project meets all requirements and maximizes functionality and aesthetics.

Hiring an Architect or Designer

You'll need to hire an architect or designer to create plans for the structure. Alternatively, you can use a reputable ADU prefab company with experience in your county. The plans must meet all local building codes and include details such as materials, windows, doors, bedrooms, and bathrooms.

Finding the Right Contractor

Selecting the right contractor is crucial for a successful ADU project. Look for builders with specific experience in ADU projects in San Jose, like May Construction. They should be familiar with local building codes and the permitting process.

Contractor Credentials

Ensure your contractor is licensed and insured. Check their credentials and reviews to ensure they have a good reputation.
