⭐ Local ADU Expertise — Kenji Inui: Kenji closely tracks Anaheim’s ADU ordinance (AMC 18.38.015), including the city’s ADU Express program with pre-approved detached plans, 4-foot side and rear setback standards, height limits for detached units, and restrictions in sewer-limited and SB 9 two-unit/urban lot split areas. He regularly reviews ADU Anaheim submittal checklists and owner-occupancy covenants for JADUs to help buyers and owners avoid costly surprises during permitting.

Why Are ADUs a Smart Move in Anaheim’s Housing Market?

  • ADUs in Anaheim can add substantial resale value. Properly permitted detached ADUs, garage conversions and junior units often strengthen the property’s appraisal profile and make it more competitive in a tight Orange County market.
  • Anaheim sees consistent rental demand for second units. Proximity to the Anaheim Resort, convention center and major job corridors supports year-round demand from hospitality workers, service employees and local families seeking flexible housing.
  • State law and Anaheim’s ordinance support streamlined ADU approvals. California ADU law and Anaheim’s own standards allow attached or detached ADUs on lots with a primary residence, with reduced 4-foot side and rear setbacks for many detached units when the project meets code requirements.
  • Anaheim offers ADU Express pre-approved plans for detached units. Qualified projects can use pre-approved designs to shorten plan review times compared to fully custom applications, while still following local height, separation and utility standards.

What Should Anaheim Owners Know About ADU Rules and Financing?

For official standards, see the city’s ADU Anaheim resource page, which links directly to the municipal code and submittal checklists.

Q: How big can a detached ADU be in Anaheim?

A: Under California law, detached ADUs can typically be built up to 1,200 square feet when site conditions and local standards are met, with Anaheim applying its own height and setback limits to protect neighborhood character and access.

Q: Can I build multiple ADUs on a multifamily property in Anaheim?

A: Yes. State law allows a combination of detached ADUs and interior conversion ADUs on qualifying multifamily lots, subject to building, fire and parking code requirements as interpreted in Anaheim’s ADU ordinance.

Q: Is owner-occupancy required for my ADU in Anaheim?

A: For standard ADUs, owner-occupancy may not be required because California’s AB 976 permanently prohibits local agencies from imposing owner-occupancy requirements on ADUs permitted under state law. Junior ADUs (JADUs), however, still require an owner-occupancy covenant under state code and Anaheim’s submittal checklist.

Q: What are common permitting pitfalls for Anaheim ADUs?

A: Projects can be delayed when they are proposed in sewer-limited areas, on parcels already using SB 9 two-unit or urban lot split provisions, or on historic/Mills Act properties that must meet additional design and preservation standards. Early review with an ADU-literate agent and designer helps avoid dead-end concepts.
