Calabasas
Trusted ADU builder in Thousand Oaks. Construction by Maya builds beautiful, fully permitted ADUs and garage conversions, ideal for extended family, rental income or flexible living.
Thousand Oaks lots are generally larger than what you find closer to Los Angeles, and that changes the conversation. Where many homeowners elsewhere are limited to converting a garage, plenty of properties here can support a genuine detached unit in the back yard. The question is usually which path suits your parcel, not whether one exists.
Founder Hila Hemo leads our boutique team with a listening-first approach. First, we review your lot honestly. Then our licensed team handles design, permits and construction. Finally, we hand over a fully permitted unit ready to live in or rent. Above all, pricing stays clear at every step.
As an experienced ADU builder in Thousand Oaks, we tailor every unit to your property and your plans. Moreover, we bring every trade under one roof. So your project runs with one team and one clear plan, from a garage conversion to a brand-new detached unit.
New standalone backyard units with full kitchens and baths. Perfect for rental income or extended family.
Turn an unused garage into a bright, comfortable living space. Often the fastest, most affordable ADU path.
Additions connected to your home with a private entrance. Great for multigenerational living.
Compact units created within your existing home. Smart, efficient and budget-friendly.
Every unit gets a functional kitchen and beautiful bathroom. Built with the same care as our main-home remodels.
Plans, engineering and city permits handled for you. We know California ADU law and local requirements.
All four types are legitimate. However, one of them is usually clearly right for a given lot, and picking the wrong one is an expensive way to find that out. Here is how we decide with clients in Thousand Oaks.
Most builders will not discuss numbers until they have walked your property. We think that wastes your time. Below are the ranges we typically see for Thousand Oaks and Conejo Valley lots, with realistic timelines from design through final inspection.
| ADU Type | Typical Investment | Timeline With Permits | What Drives The Range |
|---|---|---|---|
| Junior ADU | $60,000 - $120,000 | 3 to 5 months | Built within the existing home, so cost follows kitchen and entry scope |
| Garage Conversion | $90,000 - $180,000 | 3 to 6 months | Slab condition, plumbing runs, panel upgrade and insulation requirements |
| Attached ADU | $150,000 - $280,000 | 5 to 9 months | Square footage, roof tie-in, structural work and separate utility service |
| Detached ADU, 400 to 800 sq ft | $200,000 - $320,000 | 6 to 10 months | Foundation, utility trenching distance, site access and finish level |
| Detached ADU, 800 to 1,200 sq ft | $300,000 - $450,000+ | 8 to 12 months | Size, grading on sloped lots, custom design and appliance package |
| Design & Permitting Only | $12,000 - $25,000 | 2 to 5 months | Architectural plans, Title 24, structural calculations and city fees |
These ranges reflect typical Thousand Oaks and Conejo Valley lots. They are a planning guide, not a quote, and they exclude city impact fees, which vary. After we review your parcel, you receive a written, itemized price with no hidden allowances.
Our ADU process in Thousand Oaks stays simple, transparent and collaborative. First, we listen. Then, we plan every detail with you. Because of this, you feel confident from the first call to the final reveal.
First, we meet at your Thousand Oaks property. We review your lot, goals and budget together.

Then our crew builds with precision. Meanwhile, you receive weekly progress updates with photos.
Finally, we complete a careful walkthrough and final inspections. Your unit is ready to live in or rent out.
Siting an ADU in Thousand Oaks involves one constraint most cities do not have. The city protects its oaks, and a protected tree's root zone extends well past its canopy. A back yard that looks wide open can have far less buildable area than it appears once those zones are mapped.
Add the hillside lots common in Lynn Ranch and Conejo Oaks, where grading and equipment access shape the budget, and siting becomes the decision that drives everything else. So we resolve it first, before you pay for design.
Tree, hillside and zoning requirements vary by parcel and are updated periodically. We confirm the current rules for your specific property during your free feasibility review.
Send us your address and what you are hoping to build. We will tell you what is realistic for your parcel, your trees and your budget before you spend a dollar on design.
Book A Free Feasibility ReviewWe bring ADU expertise to every Thousand Oaks neighborhood and the Conejo Valley. Also, we know the local HOA rules, lot requirements 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 ADU, garage conversion and addition work from our team across the Conejo Valley and greater Los Angeles.
An ADU in Thousand Oaks opens up endless possibilities. For example, you can house aging parents, welcome adult kids back home or earn steady rental income. From concept to keys, we turn your back yard into your best investment.
There is no shortage of ADU companies in the Conejo Valley. Here is what makes working with a small, owner-run builder different.
We map trees, setbacks and slope before you pay for design. Consequently, you never spend months on plans for a unit that was never going to fit where you imagined it.
If a garage conversion serves you better than the detached unit you asked about, we will say so. A smaller correct project beats a larger wrong one.
Clients mention this in their reviews unprompted. On a build that can run most of a year, you should never wonder what happened this week.
Plans, Title 24, structural calculations and city submittal are handled in-house. Therefore you are not coordinating an architect, an engineer and a builder who blame each other.
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.
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 Thousand Oaks, Calabasas and the Conejo Valley say about building with our team.
An ADU is the largest project most homeowners ever take on. The ones 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.
The answer changes the layout, the entrance, the parking and the finish level. A unit for your mother and a unit for a tenant are not the same building at the same square footage.
Protected trees shape where a unit can sit, and their root zones reach further than most people expect. Worth knowing before you picture the building anywhere specific.
If it holds storage you actually need, converting it creates a new problem. Sometimes a detached unit plus keeping the garage is the better total answer.
Trenching to sewer, water and gas is one of the biggest hidden costs on a deep lot. Distance and what sits between here and there matter more than expected.
Cash, a HELOC and a renovation loan each have different timing implications. Knowing which one you are using shapes when we can realistically start.
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 later.
