How an ADU Can Add a Rental Income to Your Long Beach Home

Dustin Edwards • May 16, 2023

An accessory dwelling unit (ADU) is the concept of adding or modifying a property that would be a single-family home to allow for an additional unit. Some homeowners build them to give friends or family a place to live. This is why ADUs are sometimes referred to as “granny flats or mother-in-law units.” ADUs can be a great introduction to becoming a landlord.


Below we’ll provide more information about ADUs and why they’re becoming more popular in real estate.


Different Kinds of ADUs 

Suppose you have extra space in your backyard and are interested in building an ADU. In that case, a few variations exist, such as converting an existing garage, building above the garage, or building a separate structure. The most common form of ADU is the garage conversion. They typically already fall within the 800 sq ft or 50% of the primary residence (whichever is greater) size limits. While the majority of the structure is already built, which can economize the rest of the building. While more expensive upfront, building a separate structure allows you to take the build to its limits. This will enable you to configure the unit how you please, which can significantly affect the ADU rental income. Some cities allow building ADUs above garages. However, this is incredibly limiting and sometimes not allowed. Lakewood, for example, currently does not allow this. Although infrequent, the building code does allow for attic and basement ADUs. 


Building an ADU

While you can configure an ADU to your liking when building it from the ground up, there are regulations you must follow. As previously stated, an ADU can’t be bigger than 800 sq ft unless the main house is big enough to accommodate the extra size. When you build, remember that a dedicated parking may be required unless you are within a half mile of public transportation. ADUs must be designed for long-term rentals, meaning you cannot list them on sites like Airbnb. Remember that an ADU is similar to a duplex because it's part of the property and can’t be sold separately. Depending on your city and county, there may be other regulations for building an ADU. It's best practice to find a reliable contractor and architect to help you with your build.


Buying a Home with an ADU

Because an ADU cannot be sold separately from the house, there are some property listings with ADUs built on the property already. While some listings may outright state an additional unit in the description, sometimes you’ll need to dig deeper to find them. Carefully read the report and look at the provided pictures not to miss them.


Potential ADU Rental Income

When you have an ADU, it's similar to having a duplex. You can live in one unit while renting out the other to increase your monthly income. There are many factors to consider when analyzing how much income an ADU can provide. Such as the location, size, configuration, and what, if any, amenities you’ll be providing to the tenant. For better context, you can search how much apartments and duplexes rent in your area. That being said, ADUs can reach an income of $2,000-$2,200 per month. If you also rent the main house, you could earn an additional $3,0000-$3,300+ monthly.


ADUs are incredibly useful structures, and if you want to dip your toes and become a new landlord, they’re a great way to start. Though if you feel like you may need help finding an

With the real estate market as competitive as it is, many landlords are looking into building an Accessory Dwelling Unit (ADU) or Jr. ADU to improve their bottom line with additional monthly income. While this is a great way to earn more, you need to be sure you’re investing in the right upgrade to your property. Below are some of the key differences between ADUs and Jr. ADUs; this way, you can make the right decision for your property. Differences between Junior ADUs and ADUs On the surface, the primary difference between an ADU and a Jr. ADU is the square footage. However, there are many considerations for each type of ADU , significant differences include costs and build limitations. ADUs are generally seen as a larger and more versatile build when compared to a Jr. ADU. They can be built detached from the main home, converting an existing structure, most commonly the garage. In Long Beach, an ADU can be up to 800 square feet or 50% of the gross floor area of the primary dwelling, whichever is smaller. For reference, an 800 sqft living space can be arranged as a 2-bedroom 1-bath home, though with creative use of the space, many investors have been able to fit 2 bedrooms and 2 bathrooms comfortably. If listing the ADU for rent is the goal, this can produce a higher yield, though at the cost of a higher initial investment. Jr. ADU, on the other hand, can only be a maximum of 500 sqft and must be built attached to the existing single-family home. While you can build an entire new addition to accommodate the Jr. ADU, it's not uncommon for homeowners whose homes are bigger than they need to convert a bedroom into a Jr. ADU in order to have additional income . A Jr. ADU does still require an efficient kitchen. Bathrooms can be shared with the main house, though this can deter some prospective tenants. Additionally, the utilities are oftentimes shared with the main house, which can simplify installation, though it can complicate utility costs with your tenant. When an ADU is Right Being able to build a full ADU provides an entirely separate and private living space, which is more desirable to prospecting tenants. This is the preferred choice for most investors, especially those who have unused space in their property. By being built apart from the main house, an ADU may cause less disturbance to those living in the main house, whether that be yourself or another tenant. In Long Beach, CA. ADUs can’t be listed as short-term rentals on apps like Airbnb; that being said, an ADU can command more in rent because of the aforementioned features. If you’re looking for a long-term investment, ADUs increase your property’s value while generating a consistent cash flow. Finally, if you ever plan on selling your rental property, the additional ADU can improve the appeal of your property to future buyers. When a Jr. ADU is Right While a Jr. ADU doesn’t have the same potential as a full-sized ADU, Jr. ADUs are far more budget-friendly. These are a great option for investors who have limited funds. Since Jr. ADUs generally require less work to be done in less time, allowing you to begin making a return sooner. Finally, if your property doesn’t qualify for a full-sized ADU permit due to the size of the property lot, a Jr. ADU can be built primarily through interior work, which may only require reconfiguring existing interior space. Whether you choose a full-sized ADU or a Jr. ADU, the decision depends on more than just the size of the structure, you’ll have to manage filling the vacancy and managing the new tenant.

Summer is a great time of year where people enjoy a number of outdoor activities. Though for landlords, summer brings with it a list of maintenance items and preventative care for their properties. Below, we’ve gathered three of the most important maintenance items to do before summer starts. Service your HVAC System Southern California summers are getting hotter and hotter, if you want to maintain tenant satisfaction you’ll need to have the HVAC or any A/C or cooling system properly serviced . Filters should be cleaned or replaced, and the ductwork should be inspected. For rentals with window units or mini-split systems should also be thoroughly inspected as well for optimal cooling. Doing proactive maintenance can reduce the risk of the cooling system breaking down during peak usage while also improving the system’s efficiency. This can lower utility costs for your tenants while extending the lifespan of your cooling system, saving you money in the long run. Additionally, consider inspecting your window and door seals for leaks. If the seals are broken, it allows hot air into the living space, this increases the cost associated with cooling while adding more load to the HVAC or cooling system. While not directly a part of the HVAC system, ensuring there aren’t any breaks in the seals helps extend the lifespan of your cooling system which is beneficial to your bottom line. Inspect your Roof The condition of a roof is oftentimes ignored since they tend to last over twenty years, and some property owners may not even be sure when the roof was last replaced . A poorly conditioned roof is one of the primary ways for a rental property to drive up the costs of repairs and tenant complaints. A damaged roof can inefficiently insulate a home, making it harder to keep it cool. It can also lead to water leaks during rainfall, which can lead to water damage, stains, and mold growth. While summers tend to be dry, the coastal cities such as Long Beach may see unexpected shifts in weather, which can bring sudden rainstorms or increased humidity. Fixing a small roof leak is relatively inexpensive, however, leaving said leak to grow can result in an emergency repair can cost thousands especially if a tenant has already moved in. A thorough roof inspection is a great maintenance item to do during a vacancy period especially as this can result in a positive experience with new tenants. This can lead to a long term stay with many lease renewals. Check for Signs of Pests Pest infestations are one of the fastest ways to ruin a tenant’s stay while also damaging a landlord’s reputation. Pests such as ants, cockroaches, other bugs, and rodents are common in many beach cities, especially during the warmer seasons. Being in a city, you’ll likely never truly be rid of pests, though, even a single complaint about an excess of bugs or rodent droppings can lead to bad reviews online, service calls, and in severe cases, lease termination. These pests not only create an unwelcome environment for your tenants, but they can also cause real damage to your investment property. Cockroaches are known to damage small wiring in appliances, ants can ruin food and get in everything, while rodents can chew through walls, plumbing, and even electrical wiring. Landlords should schedule regular ppest inspectionsto check for early signs of pest activity before the hotter season begins. Much like everything in this article, preventative maintenance is significantly cheaper than an emergency call, in this case to an exterminator. If you want to keep your tenants happy and your property well taken care of, preventative maintenance is a must. If you’re unsure about the signs to look for when doing routine inspections or you need help managing your Beach City rental property, we invite you to call us today at (562) 888-0247 or complete our Owner Application online .
