SB9 and ADU Projects: How to Maximize ROI in Today’s Market

by | Sep 19, 2024

 When it comes to getting the best return on investment (ROI) for an ADU project under the new SB9 regulations, there’s a lot to consider. Over the years, I’ve seen what works and what doesn’t in the real world, and it’s not just about building an additional unit—it’s about building the right unit in the right way. Here’s what I’ve learned about maximizing ROI on these projects.

Understanding What Type of ADU Yields the Best ROI

First and foremost, it’s crucial to choose the right type of ADU that aligns with your goals. Not all ADUs are created equal when it comes to investment returns. In my experience, detached ADUs—stand-alone units separate from the main house—often offer the best ROI, especially in areas where space and privacy are highly valued. A detached ADU can function almost like a small house, which can be very appealing to renters looking for privacy or families looking for more space.

Attached ADUs, which are connected to the primary residence, can also provide good returns, but they typically appeal to a different type of tenant, such as an elderly parent or young adult. These might work best in neighborhoods with multi-generational families or where the housing market is tight.

Conversion ADUs, such as garage conversions, are a cost-effective way to add rental space without extensive new construction. However, their ROI depends heavily on local market conditions and the quality of the conversion. If done right, a well-executed garage conversion can provide substantial returns, particularly in high-demand urban areas where space is at a premium.

Location, Location, Location: The Real Determiner of Value

The location of an ADU is another critical factor in determining ROI. In areas where rental demand is high, like parts of Los Angeles or the Bay Area, even a small ADU can command significant rental income. However, in locations where the market is softer, the returns might not justify the cost. It’s essential to do your homework and understand the local real estate trends and rental market dynamics.

For instance, I’ve seen projects in bustling urban centers generate substantial income, while similar units in more suburban or rural areas have struggled to find tenants. When planning an ADU, it’s crucial to look at factors like local amenities, public transport access, and neighborhood desirability. Proximity to schools, parks, shopping centers, and employment hubs can significantly influence rental demand and, subsequently, ROI.

Design and Quality Matter More Than You Think

Another often overlooked aspect of maximizing ROI is the design and quality of the ADU. You might think that saving money by cutting corners on materials or finishes is a good idea, but I’ve found that investing in high-quality, durable materials often pays off in the long run. High-quality finishes and appliances not only attract tenants willing to pay a premium but also reduce maintenance costs over time.

An ADU that feels like a mini luxury home—think stainless steel appliances, hardwood floors, and modern fixtures—can fetch a higher rent than a basic, no-frills unit. Also, designing with flexibility in mind is key. Features like convertible spaces, extra storage, or energy-efficient appliances can make a big difference in attracting quality tenants.

Navigating the SB9 regulations is another critical piece of the puzzle. The law allows for up to two ADUs on a single-family lot, potentially doubling the income from a single property. But, to take full advantage, you must be well-versed in what’s allowed and what isn’t under the new rules.

For example, understanding setback requirements, parking regulations, and height restrictions can help you design an ADU that maximizes square footage while staying compliant. The flexibility under SB9 opens up opportunities, but it also means you need to be strategic in your planning to avoid costly mistakes.

Having a good grasp of local zoning laws and SB9 guidelines isn’t just about compliance—it’s also about optimizing your design to get the most value from the available space. Whether it’s designing a two-story ADU to maximize a smaller lot or figuring out how to provide adequate parking without sacrificing too much yard space, there are countless ways to use the guidelines to your advantage.

Leveraging SB9’s Provisions for Cost Efficiency

One of the most powerful aspects of SB9 is its ability to reduce the cost of developing ADUs. By allowing homeowners to build multiple units on a single-family lot, SB9 effectively doubles or even triples the rental income potential of a property without requiring significant additional investment in land acquisition. However, it’s crucial to understand how to leverage these provisions effectively to maximize your ROI.

For example, by utilizing SB9’s relaxed zoning rules, homeowners can convert existing structures or build new units without facing the traditional zoning hurdles that have historically increased costs and slowed down timelines. This means that a garage conversion or even a new detached unit can be done more quickly and with fewer bureaucratic delays, ultimately leading to a faster path to generating rental income.

The law also allows for the subdivision of lots, meaning a property owner can build two units on each of the newly created lots. This can significantly enhance the return on investment by increasing the number of rentable units, provided the costs associated with the subdivision—such as survey fees, legal costs, and infrastructure upgrades—are kept under control. This is where a strategic approach to the project’s planning and execution can really make a difference.

Financing Strategies to Boost ROI

Financing is another critical factor in maximizing ROI for ADU projects under SB9. In my experience, homeowners often underestimate the importance of securing the right type of financing. Traditional loans may not always be the best fit for an ADU project. Instead, specialized financing options like renovation loans, home equity lines of credit (HELOCs), or ADU-specific loans can offer more favorable terms that align with the unique nature of these projects.

One strategy is to use a construction loan that converts to a permanent mortgage once the project is completed. This can help mitigate the cash flow challenges that come with large upfront costs, allowing the homeowner to focus on building a high-quality ADU without worrying about financing. Additionally, considering the relatively high demand for ADUs in many markets, refinancing after construction could provide a better rate or free up cash for future projects.

Staying Ahead of Market Trends and Regulatory Changes

Understanding market trends and keeping up with regulatory changes is key to staying ahead in the ADU game. The SB9 law is relatively new, and its implications are still unfolding, which makes it crucial for homeowners and developers to stay informed about how local jurisdictions are interpreting and implementing the law.

For example, some cities may impose additional design standards or parking requirements despite the state law’s more relaxed approach. Being aware of these nuances can help avoid costly mistakes and delays. I make it a point to stay connected with local planning departments and participate in industry groups that monitor SB9’s implementation, which gives me a heads-up on any new requirements or changes.

It’s also essential to understand that market demand for ADUs can vary significantly depending on factors like location, demographics, and economic conditions. Areas with a high demand for rental housing, such as urban centers and cities with a high cost of living, are likely to see stronger returns on ADU investments. Meanwhile, regions experiencing slower economic growth or where the demand for rentals is not as strong might require a different approach or design to make an ADU financially viable.

Final Thoughts: Tailoring Your ADU Strategy to Maximize ROI

Ultimately, maximizing ROI on ADU projects under SB9 is about being strategic and informed. It involves understanding the unique aspects of your property, the local market conditions, and how to best leverage SB9’s provisions to your advantage. From choosing the right type of ADU and location to selecting high-quality materials and navigating the complexities of local regulations, every decision plays a role in the final outcome.

My advice? Don’t rush into an ADU project without a clear plan. Take the time to understand the regulations, explore your financing options, and be prepared to adjust your strategy as needed. The more you know about the landscape, the better positioned you’ll be to make smart decisions that lead to a strong ROI.

And remember, building relationships—whether with tenants, city officials, or financial partners—can often be the deciding factor in whether an ADU project succeeds or fails. A great ADU project is not just about adding value to a property; it’s about adding value to the community and doing it in a way that aligns with your long-term goals.
