Why Build an ADU?

An accessory dwelling unit can create adaptable space while helping homeowners make more thoughtful use of their property.

Rental income potential

An ADU may provide a separate space that can be considered for rental use, subject to local requirements.

Space for family members

Create nearby, independent living space for relatives while keeping family connections close.

Home office

Build a dedicated work environment separated from the activity of the primary residence.

Guest house

Offer visitors a comfortable, private place to stay on your property.

Increased property value

A well-planned ADU may add useful living area and long-term appeal to a property.

Flexible living space

Adapt the space over time as household needs, work, or family arrangements change.

Project Guidance

Frequently Asked Questions

What is an ADU?

An accessory dwelling unit is a secondary residential space located on the same property as a primary residence. ADUs may be detached, attached, created through a garage conversion, or configured as a junior ADU, depending on the property and applicable requirements.

How long does an ADU project typically take?

Timing varies based on the site, design, permit review, project scope, materials, and construction complexity. A project-specific schedule can be discussed after the property and proposed work are evaluated.

Can I build an ADU on my property?

That depends on property conditions and applicable local requirements. Lightning Construction can discuss the construction scope, while the appropriate local authority should confirm property-specific eligibility and requirements.

Do I need permits?

ADU construction generally requires plans, review, and permits from the applicable local authority. Requirements vary by project and location. We offer permit assistance and encourage homeowners to obtain project-specific guidance.

Can an ADU be used as a rental?

Rental use may be possible, but rules can vary by location and property. Homeowners should confirm current requirements with the appropriate local authority and seek qualified legal or tax guidance when needed.
