Introduction to ADU Investments in Escondido

Why are ADUs popular in California?

Accessory Dwelling Units (ADUs), like granny flats or backyard cottages, have become a popular fix for California's housing challenges. With home prices going up and new houses becoming less common, ADUs offer a cost-effective way for homeowners to expand their space without needing more land. These units are flexible and can be used for renting, providing affordable housing, or offering a place for different groups like young professionals, families, or seniors. They also allow families to live closer together, which helps strengthen community bonds.

How can an ADU increase property value?

Adding an ADU can boost the value of a property by providing extra space that can be rented out or used for various purposes. This makes the property more appealing to buyers who are looking for versatile living options or ways to make rental income. In California, homes with ADUs are often more valuable because they offer more options, like housing family members, earning extra income, or creating a home office. The additional space also helps the property stand out in a competitive housing market.

Is it possible to sell an ADU in Escondido?

In California, AB 1033 allows local authorities to set rules for selling an ADU and the main house separately as condominiums, as long as ADU regulations are followed. In Escondido, selling an ADU is possible under certain conditions. The ADU should be built by a qualified nonprofit organization, there should be a recorded agreement between co-owners, or the city should approve selling the ADU and the main house as separate condominiums.

The ROI for building an ADU in Escondido

We analyzed multiple projects, and we determined that on average you should expect a 30% ROI for an ADU project in Escondido. The ROI does not account for the property's acquisition cost. This ROI value is low and it signals a risky investment. Consequently, unless you have personal goals you want to achieve, we consider that an ADU project in Escondido is a risky investment. As a benchmark, a good investment for us is when the ROI is min. 50%+.

Case study: 900 sq. ft. ADU built in Escondido

Scenario 1: Build to sell

ADU Building Area

The project involves constructing an ADU with a total area of 900 square feet. This ADU is large enough for a 2 bedroom, 1 bath unit. This scenario assumes that you already own this property and there is an existing primary residential unit on site.

Total Project Cost

Based on the industry reports, the construction cost per square foot is $325, resulting in total hard costs of $292,500. Soft costs encompass various expenses incurred during the planning, design, and permitting stages of the project. These include fees for professional services such as land surveying, structural engineering, architectural design, soil engineering, and permit fees. In this case, the soft costs amount to $38,655 covering essential aspects of the project's development and approval process.

The total project cost, including hard and soft costs, is $331,155. This estimate reflects the overall investment required to complete the construction project and obtain the necessary approvals.

Total Added Market Value

The sale price per square foot for a residential house in Escondido is estimated at $480. This represents the anticipated value of the completed building per unit area in the current real estate market.

Multiplying the market value per square foot by the building area yields the total added market value. In this case, the completed project is expected to add $432,000 to the property.

ROI (Return on Investment)

The ROI provides insight into the project's profitability by comparing the total added market value to the total project cost. In this analysis, the potential gross Profit without considering acquisition or financing costs amounts to $100,845 or 30% ROI. At this level, building an ADU to sell it provides a relatively low return compared to both the costs and the market value. In addition to the low return, you’ll have to consider the short capital gain tax, in case you want to sell it before 2 year's end.

Scenario 2: Build to rent

Potential Rental Income of an ADU

Constructing a 900-square-foot ADU in Escondido comes with a total cost of $331,155. Financing with a 6.5% interest rate loan results in a monthly payment of $2,093 or $25,116/year. Ideally, renting out the main house could cover this payment, while the ADU serves as a source of additional income. Renting out a 2 bedroom, 1 bath ADU long-term could generate approximately $25,200 per year. At this rental income, which gives you a $84 possible profit per year, you probably look at paying off the loan by simply renting the ADU.

City regulations require rentals to be at least 30 days long, meaning short-term rentals are not allowed. While platforms like Airbnb can bring in extra income during peak times (for example, $600 for a five-night stay), long-term rentals provide more reliable and steady income. With long-term rentals, you won’t have to constantly find new tenants, clean between guests, or re-list the property, resulting in more consistent earnings and less upkeep.

Is there financial assistance for building ADUs?

Yes, California offers the CalHFA ADU Grant Program, which started on September 20, 2021. Homeowners who qualify can get up to $40,000 to help with upfront costs like permits, design plans, surveys, soil testing, and other necessary fees. The purpose of this program is to make building ADUs easier and provide more housing options.

Building Your Team for the ADU Project

After securing funding, check that your property follows all the necessary guidelines, including the size limits for the ADU. Decide if you want to use the unit for renting or something else, and then hire experts such as architects and builders to handle the design and construction. It's helpful to choose contractors who are familiar with local building regulations, and you can often find trustworthy ones by checking out nearby construction projects.

What are some other financing options for building an ADU?

1. Home Equity Line of Credit (HELOC)
This lets you borrow money based on your home's value, similar to a credit card. You can take out the money as you need it, giving you the flexibility to cover your ADU construction costs.

2. Home Equity Loan
This loan gives you a lump sum of money based on your home’s value, which you pay back with fixed monthly payments. It’s a simple and predictable option for funding your ADU.

3. Cash-Out Refinance
By refinancing your mortgage to a higher amount, you can take the difference as cash to help pay for your ADU, avoiding the need for an additional loan.

4. Renovation Loans
These loans are specifically for home improvements, like adding an ADU, and can cover all related costs.

5. Private Loans
Some private lenders offer loans specifically for ADUs, with terms that can be adjusted to suit your project’s needs.

Potential Challenges and Solutions

Can an HOA prevent the construction of an ADU?

No, recent laws in California (AB 670 and AB 3182) prevent homeowners' associations (HOAs) from blocking or imposing unreasonable restrictions on ADUs for single-family homes. Any HOA rules that try to stop ADUs are not enforceable and could lead to fines.
