Answers to your most common ADU building questions.

As leading ADU builders in San Diego, we provide comprehensive services covering every aspect of ADU construction. From initial design consultations to obtaining permits, construction, and finishing touches, we handle every step to ensure a smooth and successful project.

From there, our team will work closely with you to develop a customized plan that brings your ADU aspirations to life.

Yes, an Accessory Dwelling Unit (ADU) can be a good investment. ADUs offer financial benefits like rental income and increased property value, making properties more attractive to buyers. They also provide tax advantages and are versatile, serving as rental units, guest quarters, or home offices. While initial construction costs and regulatory compliance are considerations, the long-term financial returns and flexibility make ADUs a worthwhile investment.

Adding an Accessory Dwelling Unit (ADU) to your property in San Diego can increase its value by up to 30%, with some cases seeing boosts of 50% or more. The increase depends on the ADU type (detached, attached, or interior), size, quality, and the local housing market. Detached ADUs typically offer the highest value increase due to their independence, while conversions like garages may offer a higher return on investment due to lower construction costs. Local housing demand also significantly influences the added value of an ADU.

Building an ADU in San Diego typically takes 8 to 12 months. The process includes a design phase (1-2 months), a permitting phase (3-4 months), and a construction phase (4-6 months). The exact timeline can vary depending on the type of ADU and specific site conditions.

Building an ADU in San Diego typically costs:

  • 300 sq ft: $120,000 - $175,000
    • Fixed costs such as design permits and high-quality, multifunctional solutions.
  • 500 sq ft: $180,000 - $250,000
    • Economies of scale apply, with costs influenced by finishes and design complexity.
  • 800 sq ft: $250,000 - $350,000
    • Larger footprint allows for standard construction methods, potentially lowering costs.
  • 1,000 sq ft: $330,000 - $465,000
    • Costs vary widely based on location, materials, and labor.
  • 1,200 sq ft: $415,000 - $580,000
    • Maximum potential for design complexity and high-quality finishes.

In San Diego, single-family residential lots can have one ADU and one JADU, plus an additional affordable ADU and a bonus market-rate ADU, potentially totaling four ADUs. Multifamily lots can have two detached ADUs, plus conversions of non-livable spaces like storage areas and garages into additional ADUs. Special conditions, such as being in transit priority areas, may allow for even more ADUs. Always check local regulations for specific requirements.

In San Diego, an Accessory Dwelling Unit (ADU) can be up to 1,200 square feet, whether detached or attached. Detached ADUs up to 800 square feet are exempt from lot coverage requirements, and detached ADUs can be built up to 16 feet high or higher, depending on zoning regulations. Attached ADUs can be up to 25 feet high or follow the height limitations of the primary dwelling. Always consult local zoning laws for specific requirements.

An Accessory Dwelling Unit (ADU) is a secondary housing unit on the same lot as a primary residence. ADUs, also known as granny flats, in-law units, or backyard cottages, can be detached, attached, or part of the existing structure like a converted garage or room addition. They are self-contained with their own kitchen, sleeping area, and bathroom. ADUs provide rental income, affordable housing, or living space for family members, and their construction is governed by local zoning laws. Despite the costs, ADUs add property value and offer financial benefits.

Yes, you can build an ADU on your property in San Diego if it meets local regulations. Generally, ADUs are allowed in residential zones with an existing or proposed single-family or multi-family dwelling. You can have one ADU and one Junior ADU (JADU) for single-family homes and more for multi-family properties. ADU floor plans must adhere to size limits, setbacks, and parking regulations, and the property owner is not required to live on-site. Consult the City of San Diego's Development Services Department for detailed requirements and assistance.

Yes, depending on local regulations, an Accessory Dwelling Unit (ADU) can serve as a primary residence. Typically, ADUs are secondary, independent living spaces on the same lot as a primary dwelling. However, in some jurisdictions, an ADU can initially function as the primary residence, especially if built on a vacant lot or converted to the main house later. It's essential to check local zoning laws and regulations to understand your area's specific requirements and opportunities.

To finance an ADU, homeowners can explore several options:

  • Home Equity Loans and HELOCs Borrow against your home’s equity. Home equity loans provide a lump sum, while HELOCs offer a flexible line of credit.
  • Cash-Out Refinancing Replace your existing mortgage with a larger one, using the difference to fund the ADU.
  • Construction Loans Specifically for building projects, these loans convert to a regular mortgage upon completion.
  • Government Programs Look for local grants and loans, like California’s CalHFA ADU Grant Program, which offers up to $40,000 for ADU development.

One drawback of an ADU is the significant construction cost. Building an ADU can be expensive, with costs varying based on the type, such as a garage conversion versus a detached unit. Expenses for permits, taxes, utility connections, and construction can quickly add up. Despite potential rental income or increased property value, the initial financial outlay and ongoing maintenance costs are important considerations for homeowners.
