Most contractors will not discuss numbers until they have walked your home. We think that wastes your time. Below are the ranges we typically see for Westlake Village and Conejo Valley additions, with realistic timelines from permits to final walkthrough.
| Addition Type | Typical Investment | Timeline With Permits | What Drives The Range |

| Bump-Out, 50 to 150 sq ft | $40,000 - $90,000 | 2 to 4 months | Foundation work, roof tie-in and whether plumbing or HVAC extends |
| Bedroom Addition, 200 to 400 sq ft | $90,000 - $180,000 | 3 to 5 months | Size, closet and bath inclusion, and how the new roofline meets the old |
| Family Room Extension | $120,000 - $240,000 | 4 to 6 months | Span width, structural beams, glazing and connection to the kitchen |
| Primary Suite, 300 to 600 sq ft | $140,000 - $290,000 | 4 to 7 months | Bathroom finish level, walk-in closet build-out and exterior materials |
| In-Law Suite With Kitchenette | $180,000 - $350,000 | 5 to 9 months | Separate entrance, second kitchen rough-in and panel capacity |
| Second Story, 600 to 1,200 sq ft | $300,000 - $600,000+ | 8 to 14 months | Foundation and shear upgrades, new stair, full reroof and temporary weather protection |

An addition is the most heavily reviewed residential project there is. It changes your home's footprint, its structure and often its appearance from the street. Consequently, three separate approvals usually sit between you and a start date.
We manage all of them. First, we confirm what your setbacks and lot coverage allow. Then we prepare architectural drawings, structural calculations and Title 24 documentation. Finally, we submit to the city, respond to plan check corrections and carry your HOA package through design review.
Send us your address and what you are missing in the house. We will tell you what your lot can support and roughly what it costs, before you call a realtor.
Book A Free ConsultationWe bring home addition expertise to every Westlake Village neighborhood and the Conejo Valley. Also, we know the local HOA rules, setbacks and city permits well. As a result, your project keeps moving without delays.
Photos say more than any promise. Here is a look at recent addition, ADU and interior work from our team across the Conejo Valley and greater Los Angeles.
A home addition opens up endless possibilities. For example, you can add a primary suite, a bigger family room or a home office that finally fits. From foundation to matching rooflines, our team turns more space into more life for Westlake Village families.
There is no shortage of addition contractors in the Conejo Valley. Here is what makes working with a small, owner-run builder different.
Matching stucco texture, roof pitch and window proportion is the difference between an addition and an obvious bolt-on. We specify those details before framing, not after.
Hila and Moses are on your project through a build that can run half a year or more. Because we stay small, the person who quotes your addition answers your call in month five.
Structural calculations, beams and foundation design are handled in-house. Therefore you are not coordinating between an architect, an engineer and a builder who each blame the others.
Our estimates itemize labor, materials and allowances line by line. As a result, you know what a change order costs before you approve it, and surprises stay off your invoice.
Most addition work happens outside your existing walls, so we open the connection late. Consequently, daily disruption stays low through the majority of the build.
License #1034501, general liability and workers compensation on every job. In addition, we provide current certificates before work starts, without you having to ask twice.
Our reputation rests on trust and care. Above all, we deliver on our promises. So read what homeowners across Westlake Village, Calabasas and the Conejo Valley say about building with our team.
After consulting with several contractors, my wife and I made the decision to move forward with Construction By Maya based mostly on the impressive 5-Star reviews we had read. And after Moses and his crew completed the job, we understood exactly why people felt as they did...
Read moreWe just finished our ADU garage conversion with Construction by Maya. I couldn't be more pleased with the process and end results. From the very beginning, Hila and Moses were on top of everything. The weekly progress was incredible to see. I highly recommend this team. You won't be disappointed.
Read moreConstruction By Maya does fantastic work! I have worked with them on 3 different projects all that look amazing. The owners are also very helpful with guidance on materials and design choices. I will definitely use this company again for my next project!
Read moreMoses and his team were exceptional. Their knowledge and precise work on rebuilding and waterproofing our porch turned out better than we ever hoped. We will be using Maya Construction for future projects. We highly recommend them.
Read moreMoses, is the owner of the company. And his workers are very efficient. Workmanship is great. And he is very responsive to what you need and gets things done.
Read moreAn addition changes your home permanently. The projects that go smoothly are the ones where these six things were settled before design started. We work through all of them with you at no cost.
Worth pricing honestly. Between agent fees, transfer costs and current rates, staying and building is often the cheaper path, but not always. We will tell you if we think moving wins.
The point where new meets old decides how the whole house flows afterward. A well-placed addition improves the existing rooms. A poorly placed one creates a hallway to nowhere.
Adding plumbing changes both the budget and the permit scope significantly. It is usually worth it for a suite, and rarely worth it for a home office.
New square footage needs conditioned air. Sometimes the existing system can stretch. Often it cannot, and that upgrade belongs in the budget from day one.
If you are staying twenty years, build what you want. If you may sell in five, we steer you away from anything that overbuilds the street or narrows your buyer pool.
Tell us the budget you actually have, not the one you think we want to hear. Then we design to it honestly, instead of value-engineering under pressure halfway through.
