Frequently Asked Questions

Building an ADU in Long Beach typically takes 6-12 months from initial design to final inspection, depending on the project's complexity and city permitting times. The design and permitting phase can often take 3-6 months alone, as the City of Long Beach has specific requirements for setbacks, height, and utility connections. Actual construction usually runs about 3-5 months once permits are in hand. We work to keep things moving efficiently through each stage.
You can build various types of ADUs in Long Beach, including detached new construction, attached additions, or garage conversions. The type of ADU you can build depends on your lot size, existing structures, and zoning regulations in your specific Long Beach neighborhood. For example, a detached ADU often requires more yard space, while a garage conversion makes use of an existing footprint. We'll help you figure out the best fit for your property and what the city allows.
The cost to build an ADU in Long Beach varies significantly, generally ranging from $150,000 to $300,000+, depending on size, finishes, and site conditions. A basic garage conversion might be on the lower end, while a new, larger detached ADU with custom features will be higher. Site-specific challenges, like extensive utility trenching or difficult access, can also impact the final price. We provide a clear estimate after we understand your project's scope.
Yes, you absolutely need permits from the City of Long Beach for any ADU construction, conversion, or addition. This includes zoning approval, building permits, and often separate permits for plumbing, electrical, and mechanical work. Skipping permits can lead to significant fines, demolition orders, and issues when selling your property. We handle all the necessary permit applications and work directly with the city's planning and building departments.
Building an ADU in Long Beach offers several key benefits, including increased property value, potential rental income, and flexible living space for family. An ADU can provide a separate home for aging parents, a private office, or a steady income stream in a high-demand rental market like Long Beach. It's a smart investment that makes your property more versatile and valuable, especially with the housing demand in our city.
