Frequently Asked Questions

An ADU, or Accessory Dwelling Unit, is a secondary housing unit on a single-family residential lot. Building an ADU in Long Beach can provide rental income, extra space for family, or a home office. Long Beach has favorable ADU regulations, making it a smart investment for increasing property value and flexibility, especially with the demand for housing in areas like Naples and Alamitos Beach.
Building an ADU in Long Beach typically takes 6-12 months from initial design to final inspection. The timeline includes design, permitting with the City of Long Beach, and construction. Permitting can often be the longest phase, but we work to streamline it. The actual construction phase usually runs about 4-6 months, depending on the size and complexity of the unit.
The typical costs for an ADU in Long Beach can range from $150,000 to $300,000+, depending on size, finishes, and site conditions. This includes design, permits, materials, and labor. Factors like utility hookups and foundation work can influence the final price. We provide a clear, upfront estimate so you know what to expect before we start.
Yes, you absolutely need a permit from the City of Long Beach Development Services to build an ADU. We handle the entire permitting process for you, from submitting plans to coordinating with city officials. Trying to build an ADU without the proper permits can lead to significant fines and costly delays. We make sure everything is by the book.
You can build various types of ADUs on your Long Beach property, including detached new construction, attached additions, or garage conversions.
