ADU Utah: Guiding You Through the ADU Construction Process
Building an accessory dwelling unit involves far more than simply hiring a contractor and breaking ground. ADU Utah works with property owners to navigate the full scope of the ADU journey, from early planning through final inspection. Their approach is structured around helping clients understand each phase of the process so they can make informed decisions along the way.
The construction phase is one of the most involved parts of any ADU project. It spans multiple sub-phases, each requiring attention and coordination. These include:
- Permitting and approval
- Planning and site preparation
- Excavation and foundations
- Framing and rough-in
- Four-way inspection
- Insulation and sheetrock
- Finish carpentry
- Paint, flooring, cabinets, and appliances
- Final inspection
Choosing the right ADU builder is one of the most consequential decisions a property owner will make. ADU Utah advises clients to ensure any prospective contractor conducts an in-person site visit, provides real references, and demonstrates thoroughness throughout the process. A builder who cuts corners can end up costing significantly more in the long run.
Throughout construction, several inspections are required, including utility connections, foundation checks, a four-way inspection, and a final inspection. Property owners should contact their local city building department to confirm which inspections apply to their project. ADU Utah helps clients understand what to expect and how to stay organized during this process.
Keeping copies of city inspection sheets and obtaining signed lien release documents from all subcontractors are important steps that are easy to overlook. Subcontractors have the legal right to file a lien against a property if the general contractor fails to pay them. ADU Utah emphasizes the importance of requesting a full list of subcontractors from the builder and securing lien releases before the project is considered complete.
Planning, Communication, and Project Management
Effective project planning involves establishing a clear timeline, key dates, and deliverables with the general contractor. Factoring in holidays and family events helps avoid unnecessary disruptions. Construction is an inherently chaotic process, and open communication between the property owner and the ADU contractor is essential to keeping things manageable.
Managing the physical impact of construction — including dust, debris, and potential damage to landscaping — requires planning ahead. Utility and sewer line work in particular can cause significant disruption to a property's exterior. Thinking through these scenarios before work begins can reduce the overall impact.
Change orders, which occur when something deviates from the approved construction plans, should always be reviewed and approved by the property owner before any changes are implemented. Similarly, a punch list — a checklist of items to be resolved before the project is considered complete — should be walked through carefully, agreed upon by both parties, and signed off before final completion.
ADU Utah has experience assisting property owners with managing their construction projects from start to finish. As an ADU builder operating along the Wasatch Front, they understand the complexity involved in building what is essentially a complete home on an existing property.
Starting with a Clear Plan
Before any construction begins, ADU Utah encourages property owners to define their purpose for building an ADU. Whether the goal is financial — such as generating rental income — or family-related, such as housing aging parents or adult children, having a clear "why" shapes every decision that follows. An accessory dwelling unit can serve as a granny flat, an in-law suite, a detached ADU, or a backyard cottage, and the intended use should guide the design from the outset.
City regulations play a significant role in what can be built. ADU Utah has developed a city ordinance guide covering municipalities along the Wasatch Front, including cities in Salt Lake, Davis, Weber, Utah, and Summit counties. Understanding local codes early in the process helps avoid costly redesigns later.
Property limitations — including lot size, terrain, setbacks, utility access, and existing structures — also determine what is physically possible. A site plan is required as part of the building permit process, and ADU Utah can assist with developing this document. The design of the unit itself should reflect both the practical goals of the project and the type of tenant or occupant the property owner intends to accommodate.
ADU Utah provides guidance across all of these planning elements, helping clients move from concept to completed ADU with a clearer understanding of what the process involves.
