Introduction to ADU & DADU Investing

In this episode of the Real Estate Rookie podcast, hosts Ashley Kehr and Tony J. Robinson delve into the increasingly popular strategy of investing in Accessory Dwelling Units (ADUs) and Detached Accessory Dwelling Units (DADUs). Recognizing that many rookie investors feel overwhelmed by the prospect of their first real estate deal, the hosts aim to demystify ADU and DADU investing as a manageable and profitable pathway to building a real estate portfolio.

Benefits of ADU/DADU for Beginner Investors

Laika Devta Lake, a seasoned investor and advocate for ADU/DADU strategies, joins the conversation to highlight why these units are particularly advantageous for novice investors. She explains, “Because it's an accessory unit, it typically means that you can either build it on a large lot, an underutilized lot, or you can build it in an existing home where you're not even increasing the footprint of the house or the Square footage, you're just, you're just converting it into an Edu or sometimes a DADU” (02:22). This flexibility allows investors to enhance property value and generate additional rental income without the complexities of larger investments.

Selecting the Right Lot for ADU/DADU

Selecting an appropriate lot is crucial for the success of an ADU/DADU project. Laika emphasizes the importance of understanding local zoning laws and regulations: “Every city is different. Where I live in my county, there's multiple cities and every city has its own zoning and regulation” (14:13). She outlines several ideal lot types, including corner lots, alley lots, flag lots, and through lots, each offering unique benefits in terms of accessibility and space utilization. Utilizing tools like Google Maps and engaging with local wholesalers can aid investors in identifying suitable properties.

Financing a DADU Project

Financing is a pivotal aspect of ADU/DADU development. Laika shares her experience with hard money lenders, stating, “I just used a hard money lender... you just have to bring in 15 or 20% of the down for acquisition” (06:11). She explains that such lenders assess the After Repair Value (ARV) to determine the loan amount, often covering the acquisition, renovation, and construction costs based on the projected future value of the property. This approach allows investors to leverage their investments effectively without requiring full upfront capital.

Navigating Permitting and Zoning Regulations

Navigating the legal landscape is one of the most significant challenges in ADU/DADU projects. Laika warns of potential pitfalls, such as needing variances to alter zoning classifications: “Some of the red flags include zoning. If you have to get a variance to make it a daddy lot, then it's probably not worth it” (17:15). She recounts a personal experience where additional costs were incurred due to unexpected zoning requirements, underscoring the necessity of thorough pre-project research and consultations with land use attorneys.

Building and Design Considerations

The design and construction of a DADU play a critical role in its marketability and functionality. Laika advises, “Build a dadu that looks like a single family home... have three bedrooms and at least two and a half baths to a thousand square foot structure” (33:29). She stresses the importance of hiring specialized contractors who are experienced in building DADUs to ensure quality and compliance with local regulations. Investing in aesthetically pleasing and functional designs can significantly enhance the unit’s appeal to potential renters or buyers.

Assembling a Reliable Project Team

A successful ADU/DADU project requires a collaborative effort from various professionals. Laika outlines the essential team members, including land use attorneys, architects, surveyors, and specialized contractors. “You have to get a land use attorney to work with... then I work with an architect to design the dadu that is perfect for this lot” (20:54). Each team member plays a unique role in navigating legal requirements, designing the unit, securing permits, and executing construction, thereby ensuring a smooth and compliant development process.

Managing Taxes Post-ADU/DADU Construction

Adding a DADU to a property has significant tax implications. Laika explains, “Whatever the tax amount was for the existing single family home, it got divided with the dadu” (39:48). This often results in an increase in overall property taxes due to the addition of the new structure. She advises consulting with tax professionals to understand and prepare for these changes, ensuring that investors can manage their finances effectively post-construction.

Conclusion and Final Advice

In wrapping up the episode, Laika emphasizes the relative simplicity and benefits of constructing a DADU compared to undertaking extensive home renovations. “With building new construction, you're putting all of your ideas and your design elements on paper, and someone's literally drawing that up, getting it permitted. And then a builder is just building to plan. So easy” (38:02). She encourages rookie investors to consider ADU/DADU strategies as a viable and less risky alternative to traditional flipping, highlighting the potential for steady income and increased property equity.

Ashley and Tony conclude by expressing gratitude to Laika for her invaluable insights and directing listeners to connect with her on social media for further guidance. They also promote the upcoming BiggerPockets conference, urging listeners to attend for more comprehensive learning and networking opportunities.
