Accessory Dwelling Units, or ADUs, are no longer just a niche trend. Across neighborhoods from San Diego to Seattle, homeowners are spotting a golden opportunity: adding space, creating rental income, and boosting property value without moving. But before the excitement turns into regret, there’s one critical detail many overlook.
Why ADUs Are Booming
ADUs have surged in popularity for several reasons. Housing shortages are driving cities to relax zoning laws, making it easier to add a detached or attached unit. Millennials and retirees alike see ADUs as flexible spaces offices, guest suites, or rental units. In fact, a recent study by the Terner Center for Housing Innovation found that properties with ADUs can see a 20 to 30 percent increase in value when designed smartly. The appeal is clear: more space, more options, and potential income that can offset mortgage payments.
Hidden Risks Many Owners Miss
The surge in ADU projects has brought new opportunities, but it also comes with real challenges. Many homeowners underestimate how complex permits and local building codes can be. Overlooking setback rules or occupancy limits can lead to expensive fines or even require a full redesign once construction is underway. Another frequent mistake is failing to account for infrastructure demands. Plumbing, electrical systems, and parking all require thoughtful planning. At Smart Design, careful preparation helps ensure that early excitement turns into a well-executed project rather than unexpected setbacks.
Real-world example: One homeowner in San Diego began converting a garage into an ADU only to discover her local regulations required a fire-rated wall and independent utility connections. The project ballooned in cost because the planning step was skipped.
Permitting Realities: The Road Less Glamorous
Navigating permits isn’t glamorous, but it’s essential. Cities vary widely, from strict inspections to layered approval processes. Research indicates that permit delays are the leading cause of ADU project cost overruns. Homeowners who go it alone often encounter repeated plan rejections, wasted time, and rising frustration.
Street-smart advice: Start by talking to your local planning office. Collect all code documents and understand required inspections. Even a small misstep can turn your gold rush into a minefield of headaches.
Turning Excitement into Long-Term Value
Professional planning turns excitement into tangible results. Working with experts ensures that your ADU is not only compliant but also optimized for functionality, design, and long-term value.
