ADU Planning and Building Regulations

Accuracy and precision are required in designing and constructing an ADU in Huntington Beach not only to comply with local regulations but to create a warm, habitable residence. Some rules and details that should be carefully considered are:

• Size and Scale: Your accessory dwelling unit needs to be of proportional size relative to the primary residence and never larger than the maximum, based on the ADU type and property zoning. A proportional ADU will have a fit and feel as though it is supposed to be there in your neighborhood and with your current home.
• Design Compatibility: Your accessory dwelling unit needs to be in harmony with the architectural style of your primary residence and the area. Thoughtfully made design choices will have your ADU fitting well into your overall property's appearance.
• Parking and Access: Sufficient parking and easy access are essential for your ADU to be accessible. Design parking spaces and entrances to be accessible to residents and visitors and to meet with local regulations and parking requirements.
• Utility Connections: accessory dwelling units require separate utility connections such as electricity, water, and sewer. They should be installed and inspected according to local building codes so they are safe to use.
• Fire Safety: Local fire safety codes must be followed. These include smoke detectors, fire extinguishers, and adequate exit points. Ensuring fire safety will keep those who occupy the unit safe and your property protected. Fire sprinklers are generally not required unless present in the primary home.
• Energy Efficiency: Make your accessory dwelling unit energy efficient to keep down utility bills, along with the footprint on the environment. Incorporate elements like insulation, double-glazed windows, and energy-efficient appliances to make it an eco-friendly home.
• Sustainability: Use sustainable materials and green building practices in your accessory dwelling unit to decrease the footprint of your ADU on the environment. Use green alternatives in building materials and follow green building practices to improve sustainability.
• Accessibility: Design and build your accessory dwelling unit in an accessible way for all who may be using it by including elements such as wheelchair ramps and handicap-accessible bathrooms. Including accessibility into your design will make your ADU more convenient and efficient for all.

By considering these design and construction factors, homeowners in Huntington Beach can plan and build ADUs that not only comply with local regulations but also enhance property value and are comfortable, eco-friendly new living spaces.

Residents of Huntington Beach can build any of four types of Accessory Dwelling Unit to suit their personal needs and the layout of their property. Below are the principal types of ADUs you can build:

Detached ADUs

• Detached ADUs are individual structures built independently from the primary residence.

Detached ADUs are ideal for homes with large yard areas and offer the easiest means of adding living space.

Attached ADUs

• Attached ADUs involve adding an extension to the primary structure on the site. Attached ADUs share a common wall with the primary residence. An attached ADU would be suitable for individuals who would not mind being near the primary living area but also wish to have their own privacy. Attached ADUs can be designed within your existing architectural style, without disrupting continuity.

Conversion ADUs

• If you have an underused garage, attic, or basement, a conversion ADU might be in your future. A conversion ADU is an ADU constructed in an existing space that is converted into living space. Conversion ADUs are a budget-friendly way of adding extra living space without the necessity of building new, perfect for houses that have limited yard area.

Junior ADUs (JADUs)

• Small units, 500 square feet or less, built inside the walls of a single-family home. JADUs are an ideal option for homeowners who wish to build out a small addition for family members or as a rental unit.
