I do most of their concrete for foundation/flat work. I have worked with IMKAT for a couple years now. I have nothing but good to say about IMKAT. They are a professional and trustworthy company. I work alongside with all of their project managers, they’re all great people, easy to work with, and always on top of it. This is a company I would trust to build your ADU. dsevilla232024-10-03Trustindex verifies that the original source of the review is Google.

GREAT JOB done by IMKAT construction. They have finished our ADU on time. Everything was coordinated by our Project Manager David. David has been very helpful and has responded to our questions in timely manner and with good suggestions. IMKAT deserves a 5 star rating for the job. Will definitely suggest others to get their dream ADU with IMKAT construction. Thank you sandra odiase2024-09-10Trustindex verifies that the original source of the review is Google. I consider myself truly blessed to have IMKAT Construction build my home. From the initial meeting with David to working with Vitaly and Eugene, who felt like family, their dedication was outstanding. They constructed my 3-bedroom, 2-bathroom home with a 2-car garage with exceptional professionalism and transparency. The entire IMKAT team and their subcontractors demonstrated top-notch skill and flexibility, accommodating my last-minute requests with ease. Vitaly and Eugene went above and beyond to ensure my satisfaction. Their commitment and moral integrity are truly commendable. If you’re considering building a small or large ADU, add-on, or even a standalone home like mine, I highly recommend IMKAT Construction. They offered the best value for my budget compared to other local contractors. Their use of quality materials and attention to detail is evident in the final product. I feel compelled to share my positive experience so others can benefit from the same exceptional service. Reach out to IMKAT Construction—you won’t be disappointed! Todd Shumway2024-08-18Trustindex verifies that the original source of the review is Google. Had the pleasure of working with Imkat Homes for an ADU build. From start to finish they were very professional, had great communication, and overall exceeded our expectations. We didn’t feel pressure at any stage of the process and couldn’t be more pleased with the end result. To start, not only was their contract competitive, but they offered much more flexibility in terms of design, layout, and build options than what we were offered at other companies. Every member of their team was friendly, provided great communication, and were knowledgeable. This isn’t their first build and their experience and expertise speak for itself and is evident throughout the whole process. After permitting was completed, from breaking ground to keys in hand, was surprisingly quick. I am pretty impressed how fast they worked, and the coordination of every step was almost seamless. Their subcontractors were also professional, respected our property, and very skilled. Jordon our Project Manager was fantastic. Responsive, friendly, honest, and genuine. He’s also very knowledgeable, experienced, and communicated efficiently at every stage. Really good guy. The only real problems that occurred throughout the build were more related to utility issues that were out of their control. I truly felt they did everything to ease our concerns and they addressed the issue professionally and honestly. I am so happy that we chose to go with Imkat. I have zero regrets and would recommend them to anyone looking to build an ADU. Their work is top-notch both in quality and professionalism, customer service was outstanding, and they handled every step with grace. Will be doing business again in the future, no doubt about it.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

FAQ
Frequently Asked Questions About ADUs
Everything You Need to Know About Building an ADU: Costs, Permits, Benefits, and More
ADUs offer several advantages:
Affordable Housing: They provide an affordable housing option without the need for purchasing additional land or major new infrastructure.
Additional Income: Homeowners can generate rental income by leasing the ADU.
Family Flexibility: ADUs allow extended families to live close together while maintaining privacy.
Efficient Use of Space: They make use of underutilized spaces, enhancing property value and utility.
ADUs can share utilities with the main home or have separate meters. Some cities require separate sewer and water connections. Our ADU consultants will assess your electrical panel to determine if it can support your ADU or if an upgrade is needed.
Our costs range from $125,000 to $300,000+, depending on size, location, and materials. Garage conversions are typically the cheapest, while detached ADUs are the most expensive.
View some of our models and consult with our ADU specialists for pricing.
Our pricing does not include utilities and permits as they vary by property.
Permits are required for construction, zoning, and utilities. The permit process takes 3-5 months and varies by city. California law requires cities to approve or deny ADU applications within 60 days.
The entire ADU process typically takes 6 to 12 months, with construction lasting around 3-4 months.
- Permitting & Design: 3-6 months
- Construction: 3-4 months
Our team will help navigate permits and ensure a smooth, efficient build

- Attached ADUs: Up to 50% of the primary home's size (or 800 sq. ft., whichever is larger).

Be aware that ADU size limits may vary by county and are subject to local zoning regulations. For exact requirements, consult your county officials or speak with one of our representatives for more information.
Generally, no—ADUs are part of the main property. However, California’s SB 9 law allows lot splits in certain cases, which may enable separate ADU ownership.
For more details, check with your local planning department or contractor.
In California, adding an ADU increases property taxes only on the new unit, not the main home. The tax hike is typically 1–1.5% of the ADU’s assessed value. For a $200K ADU, expect an annual increase of $2K–$3K. Prop 13 caps future annual increases at 2%. Consult your county assessor for exact details.
