EcoStar Remodeling & Construction is a home addition contractor for homeowners in the Bay Area, Los Angeles and our other California offices. As a licensed general contractor (CSLB 1034806), we design, permit and build room additions, second stories and sunrooms under one contract.
Your home may have started off the perfect size. Three bedrooms, two bathrooms, and a finished basement felt like more space than you really needed when you first purchased it. But as your needs changed, home additions became the perfect solution. Then along came your first two children. Your children started begging for pets, and now you have two cats and two dogs to share space with as well.
And before you know it, a third baby is on the way. What was that about having more space than you needed? If you’re starting to outgrow your home, you might be tempted to start looking for a new one. However, there is another solution: home additions! Home additions are a great way to expand your living space.
Our team at EcoStar Remodeling, in Los Angeles, the Bay Area and Sacramento, is ready to transform your home and get you back the breathing room you deserve.
EcoStar Remodeling was founded in 2010 by Robert Brown, a leading industry expert in home remodeling. It has always been the company’s goal to do every project well. After 12 years, our team is confident that we have reached that goal, and we only continue to get better with every project.
We understand that our customers have high standards, and we seek to not only meet but exceed them. You can count on quality when you choose EcoStar for your projects!
But these days, how do you know who you can trust? There are plenty of scammers or unqualified contractors out there advertising themselves as professionals. We understand that you need to feel comfortable before you let someone work on the home you’ve invested so much into.
Rest assured, the team at EcoStar Remodeling is fully licensed and insured. We are more than qualified to complete home additions and many other projects for Los Angeles residents!
1. Visit and feasibility. We measure the house, look at the lot lines, setbacks, the foundation and the roof, and tell you which kind of addition the property and your city rules allow before any design money is spent.
2. Design and engineering. We draw the floor plan and elevations so the new rooms match the existing roof lines, windows and finishes, and a structural engineer sizes the foundation, beams and connections that tie the addition into the house.
3. Permits. We assemble the plan set with the energy calculations, file it with your city, answer the plan check comments and keep you posted until the building permit is issued.
4. Build and inspections. Excavation and foundation come first, then framing, roofing, windows, rough plumbing and electrical, insulation, drywall and finishes, with a city inspection at each stage before the next one starts.
5. Tie-in and walkthrough. The wall between the old house and the new rooms is opened last, so most of the work happens outside your living space, and we walk the finished addition with you before the final sign-off.
If the lot is tight or the setbacks are strict, we compare a ground-floor addition with a second story or a garage conversion side by side, with the trade-offs in cost, yard space and disruption written out for you before you choose. Throughout the build, we sequence the trades so the inspector, the framer and the electrician arrive in the right order, and we tell your household ahead of time what to expect each week.

Moving means agent fees, transfer taxes, moving costs and a new mortgage, while an addition keeps your neighborhood and your schools and puts the money into space you design yourself. Below are the main reasons to add on rather than buy, followed by the trade-offs you should weigh carefully before you decide which way to go with your own house and budget:
Homes are one of the most expensive items you can purchase. They can cost anywhere between $250,000–-100,000,000. The more space needs you have, the more you will pay for a home.
A five-bedroom residence will obviously cost more than a two-bedroom home. Thus, if you are on a budget, purchasing a new home may not be a good idea.
Home additions, on the other hand, are cheaper than purchasing a new home. The costs usually range between $20,835 to $72,552. On average, homeowners pay about $46,498 for their projects.
Most buyers can’t afford to purchase a home outright. The most they can do is sink their savings into a down payment to lower the costs of their monthly mortgage. Mortgages usually last 30 years.
That means you are locked into a huge, long-term commitment when you purchase a home. You’ll have to keep paying a significant amount of money to the bank every month over an extended period of time.
But home additions are cheaper, meaning that you don’t have to be locked into any long-term commitments. Even if you choose to work with a financing company to help fund your project, you won’t have to go into debt for three decades.
In case of unforeseen costs due to property damage or any mishap, our remodeling company is fully insured and will cover the costs of damages.
Are you planning to stay in your home forever?
Chances are, you’re going to move on from your property eventually.
That means you’ll want to make a profit from your home when you go to sell it. Home additions are an excellent way to increase your property’s value.
Most improvement projects such as remodeling and expansion make your home more valuable and attractive to buyers.
An addition can raise what your house is worth, especially when it adds a bedroom or a bathroom.
Room addition or bump-out. A new bedroom, office, family room or larger kitchen built out from the ground floor, on a new foundation tied into the house. A bump-out extends one room a few feet; a full room addition can add a suite with its own bathroom.
Second-story addition. When the lot has no room to grow outward, building up adds bedrooms and bathrooms without losing yard space. An engineer checks the foundation and walls, and the roof comes off over the new floor.
Sunroom or California room. A sunroom is enclosed in glass; a California room keeps a permanent roof and walls tied to the house with at least one side open. Both bring light and outdoor living into the floor plan. Garage conversion or ADU. For a separate living space, see our ADU builder page.
Yes. An addition changes the structure, the footprint and usually the plumbing and electrical, so it needs plans, structural engineering and a building permit. The city checks setbacks, height and lot coverage; in the City of Los Angeles the Department of Building and Safety (LADBS) runs plan check and inspections, and in the Bay Area each city's permit center does. New conditioned space must also meet the California Energy Code (Title 24, Part 6), whose 2025 edition takes effect on January 1, 2026. We prepare the plan set, file it and meet the inspector at each stage.
Everything comes with its pros and cons. The main drawback of getting a home addition is going through the construction process, and this can cause some discomfort for you and your family.
You’ll hear loud noises all day as we build your new addition, and you’ll have to share your space for the majority of the day with contractors that you barely know. Additionally, you may notice some dust and debris that keeps reappearing as the work goes on.
But please know the team at EcoStar is careful to clean up after ourselves, and these discomforts are only short-term.
For most families who want to stay where they are, yes. The construction phase is disruptive, but it is temporary. We suggest going through with a home addition if you are interested. You’ll love the increased space you get when all is said and done.
Our team is ready to answer your questions and help you through the home improvement process. You can trust us to walk alongside you every step of the way, from design to construction. Contact our team today to learn more and get a free quote for your project!
Yes, you need permits for all major home remodeling projects. You don’t have to worry about attaining those permits yourself, though. We can help you get the proper permits for your home addition.
A home addition project can take anywhere between 2–7 months. It depends on how big your addition is, what materials you choose, and many other factors. We can give you a more specific time estimate once we know some information about your project.
Yes, of course. Communication is an essential part of completing any project. Our team is here to address any questions or concerns you may have as we build your home addition, and we’ll always keep you in the loop.
The costs of a home addition vary greatly based on factors such as the size of your project and which materials you choose. We can give you an estimate if you share details about your prospective project with us.
Sadly, any construction project is messy. Materials like sawdust and plaster will inevitably settle on surfaces around the area. However, our team is careful to clean up after themselves.
It depends on the lot and what you need: a room addition or bump-out where the yard has space, a second story where it does not, a garage conversion or ADU for a separate living space, and a sunroom or California room for light and indoor-outdoor living. We look at setbacks, the foundation and the roof before we recommend one.
Yes. A second story needs an engineer to check that the existing foundation and walls can carry the new floor, a new stair, and roof and framing work; it adds space without using the yard.
