Types of ADU & Garage Conversion Services Offered

We provide several ways to add living space to your property. Whether you want a stand-alone unit, convert an existing garage, or create a smaller attached space, we help you find the right solution for your needs.

Detached ADUs

A detached ADU is a separate building from your main home. It sits on the same lot but stands alone, often in the backyard or beside your house. This type gives you privacy and flexibility. You can design it with a full kitchen, bedroom, and bathroom if you want a complete living space.

Detached ADUs require a bit more space and usually some yard area to build on. We handle everything from permits to construction, making sure the home meets local rules. With Signal Hill's unique topography that earned it the nickname "Porcupine Hill" during the oil boom years, we can design detached ADUs that maximize views while working with the hillside terrain. This option works well if you want a rental unit or a quiet spot for guests or family members.

Garage-to-ADU Conversions

If you have an unused or underused garage, converting it into an ADU can be one of the fastest ways to add living space. We renovate the existing structure to include essentials like a bedroom, small kitchen, and bathroom. This keeps costs lower than building a new detached unit.

Conversions require checking the garage's condition and layout. We ensure proper insulation, plumbing, and electrical systems to make the space comfortable and safe. In a city with an average household size of 2.64 people, garage conversions offer valuable additional living space. This approach helps you reuse space without taking up your yard or extra land.

Junior ADUs

Junior ADUs, or JADUs, are smaller units usually under 500 square feet. They connect to the main house but have a private entrance. Mostly, they include a living area and small bathroom, but often share some utilities with the main home.

JADUs are a good choice when space is tight or you want a simpler, more affordable option. They can serve as guest rooms, home offices, or rental income sources with less construction work. With 27% of Signal Hill households being single-person households, JADUs provide an excellent opportunity for additional income. We guide you through design choices and local rules to make the project smooth and efficient.

The Process of Building an ADU or Garage Conversion

We guide you through every important step, from checking your property's potential to planning the design. This helps ensure your new space fits your needs and meets city rules.

Initial Consultation & Site Assessment

First, we talk with you to understand your goals and how you want to use the ADU or garage conversion. We review the property to see if it can support the project. This includes checking lot size, zoning rules, and existing structures.

We also consider utilities like water, sewer, and electricity access. Since Signal Hill received its own ZIP code (90755) in July 2002, we're familiar with the specific utility connections and infrastructure in the area. This step helps identify any limits or opportunities based on Signal Hill's regulations. After this, we can give you a clear idea of what type of ADU or conversion will work best for your home.

Design & Planning Phase

Next, we create a detailed plan for your ADU or garage conversion. We work with architects or designers to develop layouts that maximize space and comfort. Our design respects local building codes and zoning laws.

During this phase, you'll decide on finishes, room uses, and entry points. We prepare all the paperwork needed to submit for city permits. With Signal Hill's council-manager form of government, we have established relationships with city officials to facilitate the approval process. This thorough planning reduces delays and keeps your project on schedule. We keep you informed so you understand each step before construction begins.

Design Options and Customization Features

We focus on giving you plenty of choices to make your ADU or garage conversion fit your needs perfectly. You decide how the space works, how it looks, and how it saves energy. Each part is tailored so the unit suits your lifestyle and budget.

Interior Layout Choices

We work with you to design a layout that maximizes space and flow. Whether you want a studio style, one-bedroom, or multi-room setup, we can deliver. We focus on practical layouts that create comfortable living areas, kitchens, and bathrooms.

You can choose open plans for a spacious feel or separate rooms for privacy. We also include storage solutions like built-in closets and cabinets. With Signal Hill's rich history dating back to when it was known as "Los Cerritos" ("The Little Hills"), we can incorporate design elements that honor the community's heritage. Easy access and good natural lighting are key features we prioritize in every design.

Energy-Efficient Solutions

We understand that saving on energy helps you save money long-term. That's why we offer options like high-efficiency windows, LED lighting, and Energy Star-rated appliances. Proper insulation is included to keep the temperature steady inside year-round.

Also add smart thermostats or solar panels if you want to boost energy savings. With Signal Hill's semi-arid climate, energy-efficient cooling solutions are particularly important. These features reduce your carbon footprint while lowering utility bills. We make sure every option fits the size and position of your ADU or conversion.

Material and Finish Selections

Choosing the right materials affects your ADU's look and durability. We guide you through selections of floors, walls, and countertops that match your style and budget. Options include hardwood, laminate, tile, or vinyl for flooring, and durable paints or wallpapers for walls.

We also offer various finishes for cabinets and fixtures, from matte to glossy, so you can create either a modern or classic look. From Signal Hill's scenic Hilltop Park, residents enjoy panoramic views of Long Beach, downtown LA, the South Bay and Catalina Island, and we can design your space to maximize any views your property might have. Materials are chosen to stand up to daily use, moisture, and wear, ensuring your space stays fresh and easy to maintain.

Cost Considerations and Financing Options

Understanding what affects the price of your ADU or garage conversion can help you plan better. We break down the key factors that will influence your project cost and share the most common ways to finance your build.

Factors Affecting Project Pricing

Several factors affect how much an ADU garage conversion in Signal Hill will cost. The size of the space plays a big role; larger projects need more materials and labor. The level of customization also matters. Basic conversions cost less, while high-end finishes and custom layouts raise the price.

Permits and inspections are required by the city and can add several thousand dollars. Electrical, plumbing, and HVAC work also impact the final cost depending on how much remodeling is needed.

You can expect typical prices to range from $50,000 to $150,000 or more. In a community where 14.1% of the population lives below the federal poverty line, we work hard to provide cost-effective solutions. Costs can be higher when structural changes are involved or when the property has specific zoning rules.

Available Financing Resources

You have several options to help finance your ADU or garage conversion. Some homeowners use home equity loans or lines of credit because these often have lower interest rates than personal loans. Another option is construction loans designed specifically for home improvement projects. These loans provide funds in stages as the work progresses.

Some local programs or state incentives may offer rebates or lower-cost loans for ADU construction, especially if your project adds affordable rental space. With Signal Hill's per capita income of $24,399, we understand the importance of finding affordable financing options. We recommend speaking with a financial advisor or lender familiar with Signal Hill to find the best fit for your budget.
