Bring Your ADU Vision to Life



Accessory dwelling units—often called ADUs—are quickly becoming one of the most versatile and profitable ways for homeowners to generate passive income. Whether you’re envisioning a cozy short-term vacation rental, a long-term backyard cottage, or a flexible space for multigenerational living, ADUs offer exciting new possibilities for property owners.
With roughly 32.6 million Americans now working remotely, domestic travel on the rise, and demand for affordable housing at historic highs, the market for alternative rental options has never been stronger. And thanks to updated zoning laws, streamlined approvals, and even grants aimed at expanding affordable housing, many U.S. cities are making it easier than ever to build one.
But not all markets are equally supportive—and location is key when it comes to maximizing your ADU’s potential. Below, we’ve highlighted some of the best U.S. cities where homeowners face fewer barriers to backyard construction—and where demand for detached rentals, whether for short-term stays or long-term housing, continues to grow.
Los Angeles may be known as the “City of Dreams,” but in recent years, it’s also earned another title: one of the top U.S. cities people are leaving due to skyrocketing housing costs. To combat this trend and address staggering housing costs, the city has rolled out several initiatives designed to make building accessory dwelling units (ADUs) easier and more appealing for homeowners. These programs often include reduced permitting fees, streamlined approvals, and even property tax exemptions for ADU owners, particularly those willing to rent to low- to moderate-income tenants.
Even if income-restricted rentals aren’t part of your plan, it’s worth noting that Los Angeles remains one of the most desirable places in the country—if not the world—to live and visit. As the heart of the entertainment industry and home to world-famous attractions, beaches, and cultural landmarks, the city draws roughly 49 million visitors each year. This constant flow of tourists means ADU rentals here aren’t just practical—they’re highly profitable. Whether you’re catering to vacationers seeking a short-term stay near Hollywood or local professionals searching for affordable long-term housing, a well-designed ADU in Los Angeles offers a reliable path to steady passive income and increased property value.
Second only to California, Oregon is one of the most ADU-friendly states in the country. Homeowners in many cities, from the southern valley to the central high desert and Portland in the north, can take advantage of ADU-specific grants, low-interest financing programs, permit fee waivers, and reduced building costs. Of all these cities, however, Portland offers the strongest potential for homeowners looking to profit from an ADU rental, especially those catering to short-term visitors or local professionals seeking flexible housing.
One of the biggest reasons to build an ADU in Portland is its thriving tourism and short-term rental market. Visitors are drawn to distinctive, detached accommodations—from tiny homes and backyard cottages to converted garages tucked into quiet residential neighborhoods. In fact, many of Portland’s most desirable destinations are found in its vibrant Northeast and Southeast districts, where walkable streets, quirky shops, and craft breweries make staying in an in-neighborhood ADU particularly appealing. For homeowners, that demand translates into consistent bookings and an opportunity to generate meaningful passive income while adding long-term value to their property.
Like Oregon, Washington is an incredibly ADU-friendly state, with the region allowing up to two ADUs per lot, removing strict owner-occupancy requirements, and easing parking restrictions in many urban areas. Seattle, in particular, has embraced these changes and streamlined the process of building backyard cottages and basement apartments, opening the door to new income opportunities for homeowners.
Combine that with the city’s thriving tech-driven economy, persistent demand for affordable housing, and steady influx of professionals seeking flexible living options, and it’s easy to see why Seattle is one of the most promising markets for ADU investment. For property owners, building an ADU here means reliable rental income, added property value, and a chance to help shape the future of housing in one of the Pacific Northwest’s fastest-growing cities.
Over the past two decades, Denver has transformed from a laid-back mountain city into one of the fastest-growing urban hubs in the country. A surge of new residents in the 2010s—drawn by the city’s strong job market, access to outdoor recreation, and desirable semi-arid climate—fueled impressive economic growth and rapid urban development. However, that same boom has also driven housing costs sharply upward, creating challenges for both buyers and renters.
In response, accessory dwelling units have emerged as a mutually beneficial solution, helping homeowners offset rising housing expenses by generating rental income while expanding access to standalone, flexible housing for local professionals and new arrivals. Whether you’re purchasing property in Denver or already own a home within city limits, adding an ADU offers a proven way to boost your property’s value and contribute to the city’s broader push for more affordable housing.
No matter where you live, accessory dwelling units represent one of the most flexible and forward-thinking ways to generate passive income and add lasting value to your property. As cities across the country continue to embrace ADUs as part of broader housing solutions, opportunities for homeowners are more abundant than ever.
While Los Angeles, Portland, Seattle, and Denver stand out as some of the best cities to invest in an ADU rental today, they’re far from the only places worth considering. Smaller cities like Bend, Oregon, and Portland, Maine, are making headlines with streamlined permitting processes and rising demand for alternative housing, while Southern California as a whole remains a powerhouse market for vacation rentals and backyard units thanks to its year-round tourism and generous ADU incentives.
With the right location and thoughtful planning, your ADU can become more than just extra space—it can be a lasting investment that builds equity and adds value for years to come.

Maybe you’re dreaming of a beautiful custom home, a hobby workshop or garage, or a horse barn with a covered riding arena just steps away. Whatever the case may be for your project, there’s never been a better time to get started on your build than the present moment.
Fall is often thought of as the beginning of school for many parents or academics, but here, we like to think of it as primetime for project kickoffs. When you consider that our process—from design to delivery—takes about 5 to 8 months on average, it makes perfect sense why the upcoming season provides an ideal time for design and material preparation.
Starting your design now allows you to prep your build for spring or summer construction, making it easier, faster, and safer for you and your building crew to assemble your design and materials package. While some clients may opt for a winter build, especially if they’re located in more temperate regions like Southern California or the Hawaiian Islands, this inevitably comes with more weather delays, limited daylight, and potentially greater costs. By initiating the design process now, you can plan for a smoother, more streamlined construction phase, providing you with greater peace of mind and savings opportunities on your investment.
Additionally, finalizing your plans early enables you to secure building permits before the spring rush, reserve contractors ahead of peak season, and acquire materials before demand drives up lead times and costs. This preparation not only keeps your project on schedule but also ensures you’ll be ready to break ground as soon as conditions allow—so you can start enjoying your new space by next summer.

Everyone has a unique vision for their perfect home life, but for us green thumbs, that vision almost always includes a beautiful backyard space filled with thriving plants, trees, and happy pollinators. Having a place where we can sit in nature, grow our favorite fruits and veggies, and care for the creatures that sustain our natural habitats is a dream come true—that is, at least, until the upkeep takes over.
Thankfully, nature gives us plenty of ways to work smarter when it comes to designing self-sustaining gardens that bloom on their own. From planting native species that thrive with little effort to capturing rainwater and composting to enrich the soil, here are a few ways to create a self-sufficient outdoor space that benefits you, your garden, and the planet.
Capturing rainfall is one of the simplest and most rewarding ways to provide your garden with a steady supply of clean, chlorine-free hydration. By collecting roof runoff in barrels or storage tanks, you can turn every rainy day into an opportunity to nourish your plants naturally, while reducing utility costs and conserving a vital resource.
A basic setup, including a downspout diverter and hose, is all you need to get started. For even greater efficiency, we recommend connecting your rain barrel or tank to a soaker hose for hands-free, evenly distributed watering that keeps roots happy and soil thriving.
If you’re looking to go a step further, or if your yard has slopes or drainage issues, consider incorporating swales—shallow trenches that redirect water—or dry wells to capture and slowly absorb excess rainwater. These passive systems work in conjunction with your rain barrels to deliver water exactly where your garden needs it.
Tempted to toss food scraps and yard clippings into the trash? Consider turning them into nutrient-rich compost that feeds your garden. Banana peels, coffee grounds, grass clippings, and fallen leaves can all be transformed into a natural soil enhancer that boosts fertility, reduces erosion, and helps your plants flourish.
Composting is one of the easiest ways to reduce household waste while enriching your soil with organic matter. By making it part of your regular garden routine, you’ll create a sustainable and waste-free system that supports healthier plants, retains moisture, and reduces your reliance on synthetic fertilizers.
When it comes to building a low-maintenance, high-impact garden, native plants are some of the best allies you can have. Naturally adapted to your region’s soil, weather, and water conditions, these plants thrive with little intervention, making them an ideal foundation for any self-sustaining space.
Not only do native and drought-resistant species conserve water and reduce the need for pesticides, but they also create vital habitats for pollinators, birds, and other beneficial wildlife. By choosing plants that are already at home in your climate, you’ll spend less time maintaining your garden and more time enjoying it—all while doing your part to preserve biodiversity and protect natural resources.
If you’re starting a garden from scratch, sheet mulching is one of the easiest and most sustainable ways to prep a new garden bed. This layered method uses everyday materials like cardboard, dried leaves, compost, and soil to smother grass, build up organic matter, and create rich, plant-ready ground.
Rather than stripping away turf with a shovel or rototiller, sheet mulching works with nature to break down grass and weeds over time while preserving the fertile topsoil layer beneath. It takes some patience—typically one to two months—but the soft, nutrient-rich soil you get by the end makes the perfect foundation for growing everything from flowers to veggies.
Lastly, keeping pests at bay doesn’t have to mean harsh chemicals or constant intervention. With the right mix of companion plants, beneficial insects, and smart garden design, you can protect your greenery the natural way.
Plants like marigolds, basil, lavender, and nasturtiums can deter common pests such as aphids, mosquitoes, and beetles, while adding beauty and fragrance to your space. Meanwhile, attracting helpful predators like ladybugs and birds can keep harmful insects in check without disrupting the environment in which your plants grow.
A self-sufficient garden doesn’t just save time and resources—it deepens your connection to nature and allows it to thrive right outside your door. With a few thoughtful additions or changes, you can cultivate a greener, more resilient backyard that’s easier to care for and all-around beneficial for the environment.
