Dedicated to Excellence
Plan an ADU around your Rowland Heights property

Local planning considerations
Compare a garage conversion with a detached ADU using the existing driveway, any grade changes, and the utility connections serving the home. Show how residents and construction workers would reach the proposed unit. A useful concept also preserves practical access for maintenance and refuse collection after construction.
Which department should I check for a Rowland Heights ADU?

Everything you need to know about Rowland Heights ADUs
Get clear, expert answers to your most pressing questions about building an ADU in Rowland Heights. From local regulations to design and construction, we simplify the process so you can build with confidence.
Rowland Heights is an unincorporated community. Begin with unincorporated Los Angeles and confirm the responsible planning, building, and other reviewing agencies for the parcel. Use the regional authority's current application guidance as the starting point.
Start with unincorporated Los Angeles Regional Planning 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: Rowland Heights requires in-person plan submissions, and certain projects may need soil reports and stormwater mitigation plans.
- Coastal Zone: Unlike some nearby areas, Rowland Heights 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.
