Our Process


From site assessment to helping you choose the right design and construction team to permits and construction management we can manage the process in its entirety or manage the parts you choose.

Our process will save you money and allow you to live your life, while your ADU is being built.

Straight-forward and transparent process


Site Assessment

This due diligence report ensures that all parameters can be met before moving into the permitting and construction phases. Prices range from $250-450 in the East Bay for ADUs on single family lots. We perform a site visit and review the zoning of the lot against your ADU preferences and provide a rough order of magnitude estimate on construction costs and permit fees.


We can help you select the right ADU for your preferences and location. We work with local designers and architects and modular home builders that have a proven track record in the East Bay and a wide variety of styles. Do you have a basement in a Craftsman home in Oakland you want to convert? We have a designer for you. Want an ultra-modern, eco-friendly detached ADU in Berkeley with modular construction? We have a designer for you too.

Design Coordination and Permitting

After we help you select the right designer/architect and engineers for your project vision, we project manage the creation of the plans and help you obtain city approvals and permits to build your ADU. We help you avoid the headache of task-mastering your team and working with local jurisdictions to get your permits. The average fee for BuildZig services $3,000-6,000 for single family lots. BuildZig fees are to manage and design process and coordinate submittals of planning and building permits. We help you manage the design of your unit, assist you in selecting the right designer for your project and help you avoid costly mistakes and delays during the submittal policy.


BZ ADU can help you build any type of ADU in the East Bay, from a basement or garage conversion or a separate unit in the back yard. Go to East Bay ADU/Costs for a summary of the costs associated with our services and information about construction pricing in the East Bay.
