Types of ADUs You Can Build in Imported item 28
Many municipalities allow several types of accessory dwelling units on residential properties. Understanding your options helps you choose the best approach for your property and goals.
Detached ADU
A standalone structure built separately from your main house, typically in the backyard. Detached ADUs offer maximum privacy for both homeowners and tenants, with their own entrance, walls, roof, and complete living facilities. In Imported item 28, detached ADUs can be up to 1,200 square feet and 16 feet tall. This option provides the most flexibility in design and placement, though it typically costs more than conversions due to new construction requirements.
- Max Size: Up to 1,200 sq ft
- Height: Up to 16 feet
- Setbacks: 4 ft from side/rear lines
- Best For: Maximum rental income, privacy
Attached ADU
An addition built onto your existing home, sharing at least one wall with the primary residence. Attached ADUs are often more cost-effective than detached units because they can leverage existing foundation, roof structure, and utility connections. They work well on properties with limited backyard space or where you want to minimize the visual impact of new construction. Many homeowners choose attached ADUs for aging parents who want proximity while maintaining independence.
- Max Size: Up to 1,200 sq ft
- Height: Matches main home
- Setbacks: Same as main structure
- Best For: Limited lot space, family housing
Garage Conversion ADU
Transform your existing garage into a complete living space. Garage conversions are often the most affordable ADU option in Imported item 28 because the basic structure already exists. You save on foundation, framing, and roofing costs while creating a valuable rental unit or family living space. Most garage conversions result in studios or one-bedroom units ranging from 400 to 600 square feet.
- Typical Size: 400-600 sq ft
- Timeline: 3-5 months typical
- Cost: 30-50% less than new construction
- Best For: Budget-conscious, quick timeline
Junior ADU (JADU)
A smaller unit of up to 500 square feet created within your existing home's footprint, typically by converting a bedroom, basement, or attached garage. JADUs must include a cooking facility (at minimum, a sink, counter, and small appliance outlet) but can share a bathroom with the main house. In Imported item 28, you can build both a JADU and a full ADU on the same property, maximizing your housing options. JADUs require owner-occupancy in either the main house or the JADU itself.
- Max Size: 500 sq ft
- Location: Within existing home
- Requirements: Owner-occupancy required
- Best For: Minimal construction, family use
Above-Garage ADU
Build a new living unit above your existing or new garage structure. This two-story approach preserves your parking while adding living space above. In Imported item 28, above-garage ADUs can reach 18-20 feet in height depending on distance from property lines. This option is particularly popular in neighborhoods with narrow lots where backyard space is limited. The elevated position often provides better views and natural light than ground-level units.
- Max Size: Up to 1,200 sq ft
- Height: Up to 18-20 feet
- Parking: Preserved below unit
- Best For: Limited lot space, maintaining parking
Basement Conversion
Properties with existing basements can convert that space into an ADU. Basement conversions require proper egress windows, adequate ceiling height (at least 7 feet in habitable areas), and may need waterproofing and ventilation upgrades. When properly executed, basement ADUs provide naturally cool living space and complete separation from the main home's daily activities.
- Max Size: Existing footprint
- Requirements: Egress, ceiling height
- Benefits: Cool temps, full separation
- Best For: Existing basements only
