Building an Accessory Dwelling Unit (ADU) or tiny home on your California property is an exciting way to expand space and increase value. Whether you live in Santa Clara, Campbell, Cupertino, Milpitas, Saratoga, or Los Gatos, careful preparation ensures that your project moves smoothly from concept to completion. At Joy Line Homes, we help homeowners navigate every step, from site planning to installation, to make ADU construction simple, efficient, and rewarding.

Start with a Site Evaluation

The first step to a successful build is understanding your property. A professional site evaluation checks slope, drainage, access points, and utility connections. This helps determine where your ADU will fit best and whether any grading, tree removal, or foundation work is required. Joy Line Homes provides full site assessments to ensure compliance with local building standards and maximize your property’s potential.

Review Zoning and Local Regulations

Each city has unique ADU requirements related to size limits, setbacks, and parking. In areas like Cupertino and Saratoga, zoning codes may differ from nearby Milpitas or Los Gatos. Partnering with an experienced modular builder like Joy Line Homes ensures your project meets all local codes before construction begins, avoiding costly revisions or delays later in the process.

Prepare Utilities and Access

Before construction begins, confirm your property’s access for delivery trucks, as modular units often arrive pre-built. Utility connections for water, power, and sewer should be clearly identified. If the site requires trenching or upgrades, complete this work early to prevent installation delays. Proper preparation helps streamline the ADU setup and reduces total project time.

Plan for Privacy and Landscaping

Once your ADU layout is finalized, plan landscape design to balance privacy and visual appeal. Fencing, trees, and garden features help define separate spaces for the main home and the ADU. Joy Line Homes also recommends adding outdoor lighting and small patios to create a comfortable transition between indoor and outdoor living areas.

Work with the Right Team

Building an ADU is easier with a trusted team. Joy Line Homes coordinates every detail, from design to permitting and installation. With our modular process, homeowners enjoy faster timelines, higher quality, and fewer construction headaches.
