01
An accessory dwelling unit, or ADU, is a secondary dwelling on the same property as a primary home. A detached ADU can provide a separate place for family or another residential use, where permitted.
Duval Construction can build a detached ADU from supplied architectural plans. Share your property location, proposed use and any drawings you already have to begin discussing the construction.
02
A garage conversion uses an existing structure as the starting point for additional living space. The layout and work required depend on the garage, its condition and the intended use.
Tell Ed what you want the converted space to include and whether you have plans prepared. The project needs to be considered as a complete scope rather than simply a change to the visible finishes.
Feasibility first
The ability to build an ADU or convert a garage into a dwelling depends on the property and the requirements that apply to it. Confirm suitability before committing to a design or assuming a particular use will be allowed.
Bring available plans, surveys and site information into the discussion. Ed coordinates engineering and permits for the construction work as required by the project.

Planning guide
The questions to settle early: who the space is for, which structure fits and what needs confirming for your property.
01
Start with who will use the space and how independent it needs to be from the main home. A place for a family member, a guest space and a different residential arrangement can lead to different questions about layout, access and the property.
Describe those needs without assuming a particular building solution is already suitable. A detached ADU creates a separate structure. A garage conversion begins with a structure already on the property. Both are services Duval Construction offers, but the work involved is different.
If you are comparing an ADU with an addition to the main house, explain that in the inquiry. Ed can discuss the construction options in relation to the intended use and available project information.
02
A detached build allows the new dwelling to be considered as a separate construction project on the site. Its relationship to the existing home, available access and proposed layout all belong in the early conversation. Supplied architectural plans help describe the dwelling you want to build.
A garage conversion starts with existing construction that needs to be understood. The current structure and intended living arrangement influence the project. An attractive interior finish does not by itself explain the work needed to adapt the building for a new use.
Neither option should be treated as automatically simpler or less expensive for every property. Share the site and available documents so the comparison relates to your actual circumstances rather than a generic example.
03
A secondary dwelling should be considered in relation to the people using both spaces. Think about how occupants will reach the dwelling, what kind of privacy they need and how much connection you want with the primary home.
Those preferences can be shared with the person preparing the architectural plans and with Ed when discussing construction. They explain the purpose of the space before the conversation narrows to materials or finishes.
For a family arrangement, include practical priorities such as separate daily routines or a quieter place to live. Specific design and site requirements still need to be established; a general ADU description does not determine the appropriate layout for every household.
04
ADU construction capability and property eligibility are separate questions. Duval Construction can build detached ADUs and convert garages, but that does not establish that a particular lot can accommodate the dwelling or intended use.
Bring the exact address and any available site information into the discussion. If you already have written guidance or project documents, identify what they cover. An answer given about another property should not be assumed to apply to yours.
Ed coordinates engineering and permits for the construction work as required. Discuss what needs to be confirmed before committing to a specific plan. Discuss the proposed dwelling size and intended use for your particular property, including any questions about rental use.
05
Include the location, whether you are considering a detached build or conversion, and the intended occupants or use. Share architectural drawings, surveys and photographs if available, and say whether those documents describe the current proposal.
Explain your budget expectations, preferred timing and the decisions you have already made. Identify questions that remain open, including whether you are still comparing an ADU with another form of additional space.
This information helps Ed understand the project before discussing an estimate. It also prevents an early conversation about a possible dwelling from being mistaken for confirmation that the property has already been approved for construction.
FAQ
Yes. Detached ADU construction is part of Duval Construction's services. Contact Ed with the property location and any architectural plans you have.
Yes. Duval Construction handles garage conversions. The construction scope and whether the intended use is allowed need to be established for the specific property.
No universal answer applies to every lot. Suitability depends on the property and applicable requirements. Have feasibility confirmed before committing to the project.
The cost depends on the site or existing structure, design, size and work involved. Request an estimate based on the specific project rather than assuming a detached build and a conversion will cost the same.
Yes. Duval Construction can build from supplied architectural plans. Share the drawings, property location and any site information available. Identify whether the plans are complete or still being revised so the construction discussion reflects the current stage of the project.
The intended use and property requirements need to be established for the specific project. Converting a garage and creating an approved secondary dwelling are not descriptions to use interchangeably without that context. Tell Ed how the finished space will be used and share any existing project guidance.
Yes. Explain the living arrangement you want, describe the existing property and identify the alternatives you are considering. Photographs and site documents can help make the discussion specific. You do not need to choose a structure based only on a general cost example.
A project schedule depends on the proposed work, property and planning requirements. Share your preferred dates as context, but do not make arrangements on the assumption that an initial inquiry establishes a confirmed construction schedule.
Request an estimate
Tell us where the property is, how you want to use the space and what plans you already have. Let us know whether you are considering a detached ADU or a garage conversion. Feasibility depends on the property, so the address and intended use give the conversation the right starting point.
