Dedicated to Excellence
Plan an ADU around your Anaheim property
Start with the property
An Anaheim ADU project should begin with a confirmed property address, records, and a clear intended use. Compare how a new unit would relate to the main home, the garage, and outdoor areas. The design brief should include privacy and practical living needs as well as a preferred architectural style.
Local planning considerations
Before adopting a standard layout, discuss the utility connections and construction sequence. Ask how owner selections, plan corrections, and changes in scope will be tracked. A coordinated document set makes it easier to compare the proposed work with the construction estimate.
What makes two Anaheim ADU estimates different?
Compare the included drawings, site work, utility connections, finish allowances, external fees, and assumptions about existing conditions. Estimates based on different scopes cannot be compared fairly using only the total price or cost per square foot.
Planning with City of Anaheim
Use the Anaheim property address to establish jurisdiction before choosing a plan. Before adopting a standard layout, discuss the utility connections and construction sequence. Ask how owner selections, plan corrections, and changes in scope will be tracked. A coordinated document set makes it easier to compare the proposed work with the construction estimate.

Everything you need to know about Anaheim ADUs
Get clear, expert answers to your most pressing questions about building an ADU in Anaheim. From local regulations to design and construction, we simplify the process so you can build with confidence.
Compare the included drawings, site work, utility connections, finish allowances, external fees, and assumptions about existing conditions. Estimates based on different scopes cannot be compared fairly using only the total price or cost per square foot.
Start with City of Anaheim and confirm jurisdiction using the property address and parcel. Identify required planning, building, utility, and other approvals before treating a concept as a complete submission.
Share the plan source, file formats, permission to use it, and any approvals. We can discuss site suitability and the work needed to develop or adapt it. A concept, catalog plan, and approved construction set are different deliverables.
Provide the address, photographs, existing plans or permits if available, household needs, budget priorities, and preferred timing. Explain which decisions are settled and which options you want to compare.
Discuss the intended use before developing the layout. Privacy, circulation, storage, laundry, maintenance, and future household needs influence the design. Rental income or future property value should not be treated as guaranteed.
The proposal should identify the actual services, deliverables, involved professionals, and responsibilities. Design-only work and construction are different scopes; permitting and specialist inputs also need to be defined.
- Maximum Size: Detached ADUs can be up to 1,200 sq. ft. or 50% of the existing home’s size; attached ADUs and JADUs are limited to 500 sq. ft.
- Setbacks: ADUs require a minimum 4-foot setback from side and rear property lines. Detached ADUs over garages must have a 5-foot setback from side and rear lot lines.
- Height Restrictions: Two-story ADUs are allowed only if the primary home is two stories; otherwise, ADUs are limited to 16 feet in height.
- Building Separation: Detached ADUs must be at least 10 feet from the main residence.
- Permitting Process: Anaheim requires in-person plan submissions, and certain projects may need soil reports and stormwater mitigation plans.
- Coastal Zone: Unlike some nearby areas, Anaheim does not require Coastal Development Permits for ADUs.
The proposal should identify the actual services, deliverables, involved professionals, and responsibilities. Design-only work and construction are different scopes; permitting and specialist inputs also need to be defined.
