Recent ADU Law Updates Affecting Sunland-Tujunga
California continues to update its ADU laws to further streamline the process and remove barriers for homeowners. Recent legislation that benefits Sunland-Tujunga property owners includes:
- AB 2221 (2023): Clarified that ADUs cannot be rejected based on the existing primary dwelling's non-conformity with current zoning. This is particularly beneficial for Sunland-Tujunga's older housing stock, where many homes may not fully conform to current zoning standards.

ADU Permitting Tips for Sunland-Tujunga Homeowners
Successfully navigating the ADU permitting process in Sunland-Tujunga requires attention to several key areas:
- Pre-Submission Consultation: Before submitting plans, schedule a pre-review with LADBS or work with an experienced ADU builder like GatherADU who can identify potential issues early.
- Complete Documentation: Ensure your application includes all required documents including site plans, floor plans, elevations, Title 24 energy calculations, and structural calculations. Incomplete applications are the most common cause of delays.

- Utility Coordination: Contact DWP (water and power) and the LA Bureau of Sanitation early in the process to determine if any utility upgrades are needed for your Sunland-Tujunga property.
- Timeline Management: The City must approve or deny your application within 60 days. If no decision is made within that period, your application is deemed approved under state law.

Phase 1: Feasibility Assessment and Site Evaluation

- Property Analysis: A thorough evaluation of your lot size (typical Sunland-Tujunga lots are 7,000-15,000+ sq ft), existing structures, setback requirements, and utility connections. Properties with larger lots in Sunland-Tujunga typically have more flexibility in ADU placement and design.

Phase 2: Design and Architecture
ADU design in Sunland-Tujunga should balance maximizing livable space with complementing the existing neighborhood character. Key design considerations include:
- Architectural Style: Sunland-Tujunga's housing stock includes Ranch homes, Equestrian properties, 1950s-60s tract homes. ADU designs that reference these architectural elements create a cohesive property appearance.
- Floor Plan Optimization: Whether building a studio, one-bedroom, or two-bedroom ADU, efficient floor plans are essential. Open-concept layouts, built-in storage, and multi-functional spaces help maximize the impact of every square foot.
- Indoor-Outdoor Connection: Sunland-Tujunga's generous lot sizes allow for private outdoor spaces, patios, or small yards adjacent to the ADU, significantly enhancing its appeal.
- Privacy: Window placement, landscaping, and ADU orientation should be carefully planned to provide privacy for both the ADU occupants and the primary residence.
- Natural Light: Strategic window placement, skylights, and clerestory windows help ADUs feel spacious and airy, reducing the need for artificial lighting during daytime hours.
Phase 3: Permitting
The City of Los Angeles has streamlined its ADU permitting process in compliance with state law. For Sunland-Tujunga properties, the permitting process typically includes:

Types of ADUs You Can Build in Sunland-Tujunga
California law allows 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 Sunland-Tujunga, 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 Sunland-Tujunga because the basic structure already exists. You save on foundation, framing, and roofing costs while creating a valuable rental unit or family living space. California law prohibits cities from requiring replacement parking when you convert a garage to an ADU, making this option particularly accessible. 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 Sunland-Tujunga, 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 Sunland-Tujunga, 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
While less common in Southern California due to construction patterns, 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

Understanding ADU costs helps you plan realistically and evaluate the investment opportunity. Here's what to expect for typical Sunland-Tujunga ADU projects.
Garage Conversion
$100,000 - $180,000Converting an existing garage is typically the most affordable path to an ADU. You save on foundation and framing since the basic structure exists.

- HVAC system
- Insulation and drywall
- Kitchen and bathroom
- Flooring and finishes
- Permits and inspections
Detached New Construction
$200,000 - $400,000Building a new detached ADU involves complete construction from the ground up. This option costs more but offers maximum design flexibility and typically commands higher rents. A one-bedroom detached ADU in Sunland-Tujunga typically costs $200,000-$280,000. Two-bedroom units range from $280,000-$400,000 depending on size and finishes.

Attached Addition
$150,000 - $300,000Attached ADUs share a wall with your existing home, which can reduce some construction costs.

Costs fall between garage conversions and fully detached new construction for most Sunland-Tujunga projects.

- Framing and roofing integration
- Separate entrance and utilities
