Understanding ADUs and What to Expect
An accessory dwelling unit (ADU) is a secondary dwelling structure located on the same residential lot as the primary residence. There are two main types: attached ADUs, which involve the reconstruction of existing interior space, and detached ADUs, which are separate standalone structures built on the property.
ADU construction involves several important stages, including learning local building regulations, completing project design, calculating costs, sourcing materials, and carrying out the actual construction or reconstruction work. For most homeowners, partnering with a professional ADU builder is the most efficient and reliable path forward.
When it comes to cost, ADU construction pricing is influenced by many factors:
- Whether the ADU is attached or detached
- The size of the residential lot and the planned ADU square footage
- Whether the structure will be single-story or multi-story
- Local permitting requirements and design guidelines
Generally, ADU construction costs can range from approximately $30,000 to over $300,000, depending on the scope and complexity of the project. As for timelines, obtaining building permits typically takes around two weeks, while construction itself can take anywhere from four to six months depending on the specific project.
ADU Builders California offers turnkey custom ADU solutions across a range of sizes, from 250 sq. ft. up to 750 sq. ft. and beyond, giving homeowners flexible options to suit their space and budget.
