When learning about a new design concept like an ADU, it’s natural to want to know exactly what that concept looks like in the flesh. We want to embed the ADU design concept in or brains as a tangible object that we can mentally reference. Let’s broaden that mental model by exploring and understanding the range of common ADU types.
Setback requirements control how close ADUs can be to property lines—typically 5-10 feet from side and rear lines. Many cities eliminated parking requirements for ADUs to encourage construction. Some areas require owner-occupancy (owner lives on-site), though this is being eliminated in many communities. Yes, most areas allow ADU rentals, making them popular for generating supplemental income. ADU rental income typically ranges from $1,200-$3,000+ monthly depending on location, size, and finishes. Check local regulations—some cities have owner-occupancy requirements mandating you live in either the main house or ADU (not both rented).
ADU vs. JADU
1-2 person households now represent 62% of the country’s households. Only 38% of the nation’s households have more than 3 or more people in them. Some cities are bringing this shadow form of housing into the light by design. Portland, Oregon, is the de facto leader in the US for this particular type of infill housing.

Homeowners get a predictable path from design to construction, with adu features that fit the property, the backyard, and long-term maintenance. ADU construction costs range dramatically based on type, size, and location, typically running $100,000-$300,000 for complete projects. Garage conversions are least expensive at $80,000-$150,000 since the structure exists. Detached new construction ADUs cost $150,000-$300,000+ depending on size and finishes.
But as I reflect on my personal experience, it actually starts to seem entirely possible. When I moved to DC, my first home had an informal ADU in the basement. Could 1/10th of all residential housing stock in the US be informal ADU-type development? If so, this means there are more than fourteen million ADUs out there. These differentiating characteristics make ADUs a distinct type of housing. Until recently, there has been a lack of common understanding around the language and best practices of ADU development.
This depends on what your local zoning code says is permissible. In other cases, an ADU may not be allowed, but alternatives such as a guest house or a detached office or bedroom with a bathroom may be allowed. Use fiberglass or acrylic tub/shower surrounds—one-piece units eliminate leak-prone seams. Wall-mounted vanities make small bathrooms feel more spacious.
Enhancing Energy Efficiency in Your ADU: A Complete Guide
For one thing, the fact that they’re secondary housing units on single-family residentially zoned lots puts ADUs into a unique category. ADUs also have some other distinguishing characteristics that help further define, differentiate, and distinguish them from other housing types. Get detailed bids from at least three contractors based on identical plans and specifications. The lowest bid isn’t always best—look for contractors who catch potential issues in your plans, suggest value engineering ideas, and provide clear timelines. Read online reviews but weight recent references more heavily.
