Types of ADU & Garage Conversion Projects

We work on different ADU and garage conversion projects to fit your needs and property layout. These projects change how your space looks and works, whether you want something separate, attached, or built inside your existing garage.

Detached ADUs

Detached ADUs are stand-alone units built separately from your main house. They usually sit in your backyard, giving you privacy for renters, guests, or family members. These units can include a bedroom, kitchen, bathroom, and living space, all self-contained.

Because they are separate, detached ADUs often require more space and may need additional permits. They give you flexibility for use and design, and they can increase your property value by adding a full home. You can customize them with various styles, sizes, and features to fit your yard and budget.

Attached ADUs

Attached ADUs are connected directly to your main home but have their own entrance. They share a wall or a part of the structure but still offer privacy. This option is a good balance between using existing space and having an independent living area.

They usually cost less than detached units since some utilities and foundation work are shared. Attached ADUs add living space without taking up extra yard area. The design can blend with your house's look, making the addition feel natural.

Garage-to-ADU Conversions

Converting your garage into an ADU is a common choice for homeowners wanting extra living space without expanding their home footprint. This change can turn an underused garage into a full apartment with a bedroom, kitchen, and bathroom.

In Los Alamitos, where 48% of city land is occupied by the Armed Forces Reserve Center and available development space is limited, garage conversions offer an efficient solution to add living space without requiring additional land. This approach aligns with the city's compact development pattern, which has a population density of 2,781.8 inhabitants per square mile.

Garage conversions save on construction time and costs because the foundation and utilities are mostly in place. However, you may lose covered parking, so it's important to consider your parking needs. This approach works well in neighborhoods where lot size is limited.

Junior ADUs

Junior ADUs (JADUs) are small units, usually under 500 square feet, created by transforming part of a home or converting a garage area. They often have a small kitchen area and a bathroom but share some utilities with the main home.

JADUs are easier to approve since they're smaller and simpler. They're ideal if you want affordable, compact living spaces for family or renting out. These units allow you to add a rental area without major construction or full detached buildings.



Financing Your ADU or Garage Conversion

Paying for an ADU or garage conversion requires careful thought about how much you can afford and which loan type fits your financial situation best. You'll want to look at loan options that match your goals and figure out a budget that keeps your project on track without surprises.

Loan Options

There are several loan choices you can consider to fund your ADU or garage conversion. The common ones include:

• Home Equity Loan or Line of Credit (HELOC): Uses your home's equity as collateral. Usually offers lower interest rates but requires good credit.
• Cash-Out Refinance: Refinances your mortgage for more than you owe and gives you the extra cash to use on construction.
• Renovation Loan: A loan specifically designed for home upgrades, sometimes bundled with your mortgage.
• Construction Loan: Funds the building process and converts to a regular mortgage once construction ends.

Each has pros and cons related to interest rates, loan terms, and approval requirements. We help you pick the loan that best fits your timeline and budget.

Budget Planning Assistance

We work with you to build a clear budget before your project starts. This includes all costs like design, permits, materials, and labor. You'll get a detailed estimate so you know what to expect. With Los Alamitos' strong economic foundation supported by major employers like UCI Health (1,100 employees), Arrowhead Products (780 employees), and Trend Offset Printing (700 employees), property investments typically retain their value well.

The city's diverse economy helps insulate property values from market fluctuations, making ADU investments financially sound long-term decisions. We also recommend setting aside 10% to 15% extra for unexpected expenses. Our team tracks spending throughout the project to keep you informed.

If you're unsure about your financial limits, we can refer you to trusted advisors who specialize in home construction financing. This way, your budget stays realistic and manageable from start to finish.

Energy Efficiency and Sustainability

When you work with us, you get solutions that reduce your energy use and lower your environmental impact. We focus on smart materials and systems that save energy and keep your new space comfortable year-round.

Eco-Friendly Building Materials

We use materials that are sustainable and have a low environmental footprint. This includes recycled steel, reclaimed wood, and low-VOC paints to improve indoor air quality. These materials help reduce waste and pollution while maintaining strong durability.

We install high-quality, eco-friendly insulation that keeps your garage conversion warm in winter and cool in summer. This reduces heating and cooling needs, lowering your energy bills. You can expect our choices to meet green building standards without compromising on style or strength. These materials make your new space both healthier and more durable for years to come.

Energy-Saving Features

Our energy-saving upgrades focus on cutting your utility costs while increasing comfort. We install energy-efficient windows with double or triple panes to reduce heat loss and block sunlight when it's hot outside. Considering Los Alamitos' climate, with average high temperatures ranging from 68°F in January to 85°F in August and approximately 9.9 inches of annual rainfall, our energy-efficient designs optimize natural lighting while providing appropriate insulation and weatherproofing. These climate-specific adaptations maximize comfort while minimizing utility costs throughout the year.

Lighting is also important. We use LED bulbs and smart lighting systems that adjust brightness or turn off automatically when rooms are empty. This helps reduce electricity use without sacrificing convenience. We also include options like solar panels and energy-efficient heating and cooling systems. These features work together to make your conversion more self-sufficient and less costly to run.
