Frequently Asked Questions
(ADU) Accessory Dwelling Unit also known as secondary dwelling units are residential structures that are situated on the same property as the primary residence. They serve as independent living spaces, fully equipped with their own kitchens, bathrooms, and living areas. Providing Homeowners & Investors with endless opportunities to generate additional income, maximizing property value & square footage, and providing additional livable space. We are specialized in ADU construction and can customize it to best fit your needs. Don’t hesitate to give us a call to our direct line at (323) 980-6816 or reach out via email at [email protected] and schedule your Free Estimate Today!
ADUs provide a wide range of valuable opportunities and benefits. ADUs offer an opportunity for supplementary rental income by renting out the unit and with the steady increase of the market, offset their mortgage payments or generate a consistent source of revenue. Another highlight of the addition of an ADU is that it can appreciably increase the overall value of a property, making it a lucrative approach to enter the real estate market as an investor by creating a long-term investment. Not Only does it provide homeowners with long term investment opportunities but now Under AB 1033, which was recently signed into law in 10/11/2023, allows property owners in participating cities to construct an ADU on their land and sell it separately, following the same rules that apply to condominiums giving the opportunity to create a short-term investment. Not only do ADU’s provide flexible living arrangements. They can serve as accommodation for extended family members, guests, or a home office, adapting to evolving household needs. Much like most of California in areas with housing shortages, ADUs contribute to addressing the demand for affordable housing options, benefiting both homeowners and renters. Many municipalities have introduced zoning regulations and incentives to encourage ADU construction, making the process more feasible and economically advantageous.
- Detached ADU: These stand-alone structures offer complete independence and privacy. Detached ADUs can take the form of a newly constructed unit or converted accessory building.
- Attached ADU: Integrated into the main house, these units are typically more cost-effective and offer a seamless connection to the primary residence.
- Garage Conversion: Transforming an existing garage into an ADU provides an opportunity to maximize underutilized space, often with an open studio layout.
- Junior ADU (JADU): These are typically smaller and located within the main house, suitable for homeowners with limited available space.
A Home Addition is a construction project that involves expanding the existing structure of a house to create additional living space. This can include adding new rooms, enlarging existing ones, or building entirely new sections. This is often done to maximize the available space in a home or to accommodate expanding families. The process can involve the addition of one or more rooms, such as bedrooms, living spaces, home offices, or bathrooms. A home addition project can also include the extension of an existing room, such as a kitchen or family room, or the construction of a completely new additional floor adjoining the house. Home additions are designed to seamlessly integrate with the existing home while meeting specific needs and preferences. It’s best to work with experienced professionals who can handle every aspect of the project and ensure a successful outcome. All in all, home addition projects can be quite complex, but by working with experts, the final product can meet all the homeowners’ needs for a comfortable home.
- Room Addition: A room addition involves extending the footprint of your home to create a new room. This can be used to increase the number of bedrooms, add a living room, a home office, or any functional space.
Features: Room additions are versatile and can be customized to meet specific needs. They can include features like windows for natural light, integrated HVAC systems, and seamless integration with the existing structure. - Second-Story Addition: A second-story addition involves building an entirely new level above the existing structure of your home. This is a practical solution when you have limited yard space.
Features: Second-story additions can include bedrooms, bathrooms, or even an entire living area. They often come with an external staircase or access from the first floor, creating a separate living space. - Bump-Out Addition: A bump-out addition expands an existing room or area of your home. It increases the floor area without requiring a full room addition.
Features: Bump-outs are cost-effective solutions to gain extra space. They can include additional square footage for a kitchen, dining area, or a bathroom. They may feature large windows for light and may require minimal structural changes. - Garage Conversion: Converting a garage into a living space is a practical solution to transform underutilized space into a functional room. This can include a guest suite, home office, or playroom.
Features: Garage conversions may involve adding insulation, flooring, windows, and other amenities to make the space comfortable and functional. They often retain the garage door for a flexible layout. - Sunroom Addition: A sunroom addition is a glass-enclosed space designed to let in ample natural light and create a seamless connection to the outdoors.
Features: Sunrooms typically feature large windows or glass walls, creating a bright and airy space. They are ideal for relaxation, indoor gardening, or as a versatile family room. Sunrooms are often equipped with heating and cooling systems for year-round use. - Mudroom Addition: Mudroom additions are designed as transitional spaces between the outdoors and the main living area. They’re practical for storing outerwear, shoes, and other items, helping keep the rest of the home clean.
Features: Mudrooms often feature built-in storage solutions like cubbies, hooks, benches, and shelves. They can also include utility sinks, laundry facilities, and space-saving design elements to maximize functionality. - In-Law Suite Addition: An in-law suite is a self-contained living space within or attached to the main home, designed for aging parents, guests, or potential rental income.
Features: In-law suites can have a bedroom, living area, kitchen, and a separate entrance. They are often designed for accessibility and privacy, with features like grab bars in the bathroom or a private patio.
Home additions offer the advantage of an optimizing solution to accommodate evolving families, changing needs, or additional functionality. They provide the space required to accommodate a growing household, precious possessions, or dedicated areas such as a home office or an expansive kitchen. A well-crafted home addition has the extraordinary ability to significantly elevate the overall value of your property, making it a strategic investment to yield returns in the long run. With a home addition, you are the architect of your dreams! The design is a canvas on which your lifestyle and personal preferences are artistically woven, resulting in a unique and tailored living environment. Relocating to a larger property can be a burdensome task. A home addition affords you the luxury of enhancing your existing residence without the upheaval of moving permanently, preserving your established roots and community ties. Home additions redefine the boundaries of comfort, empowering you to create a lavish master suite, a spa-like bathroom, an opulent living area, or an entertainment sanctuary that aligns with your refined tastes.
At M.R. Design & Build, we understand that every construction project is unique, and pricing varies depending on the specific requirements of the job. There’s no one-size-fits-all approach to pricing, which is why we offer personalized, in-person estimates. This allows us to assess the property firsthand and account for the variables that will impact the overall cost.
Here are the main factors we consider when determining pricing:
Property Features: Whether your scope will require a raised foundation or a slab foundation, these elements impact the complexity of the construction. Additionally, the property’s terrain, whether your property is on a hillside or flat land will affect grading and the overall approach to the build.
Utility Requirements: We evaluate whether your electrical panel needs an upgrade to support the new amp/watts. We also review if new separate utility lines must be installed. If tying into existing systems, we also consider the distance and complexity of the connection points.
Design and Square Footage: The overall size of the project, as well as its design (such as whether it’s a one-story or two-story structure), will influence labor and material costs. The more customized and intricate the design, the more detailed the pricing will be.
Structural Considerations: If you already have plans in place, we review them as some external engineers might not account for all construction-related costs and might over engineer so we ensure nothing is overlooked in our estimate.
Finishes and Customization: Higher-end, custom finishes require specialized labor and premium materials, which contribute to the overall project cost.
By conducting an in-person consultation, we ensure that our estimate is thorough and tailored to your specific needs, so there are no surprises down the line. This approach allows us to give you an accurate, fair price based on the true scope of your project, ensuring transparency and building trust from the very start.
