ADUs & Additions
Add Space. Add Value.
ADUs are one of the smartest investments a California homeowner can make. We handle everything — design, permits, and construction — so you can watch your property value grow.
Detached ADU
A standalone unit in your backyard. Maximum privacy for tenants or family. Ideal for rental income.
Attached ADU
Added directly to your home's footprint. Cost-effective and blends with your existing architecture.
Garage Conversion (JADU)
Convert your garage into a fully permitted living unit — often the fastest and most affordable option.
Second Story Addition
Build up, not out. Add bedrooms, baths, or an upper-floor ADU without losing yard space.

FAQ
Common Questions
Most ADU projects take 6–12 months from consultation to completion. Garage conversions can sometimes be done in 3–6 months. Permitting typically takes 2–4 months in San Joaquin County. We track all deadlines and expedite wherever possible.
Costs vary by size, type, and finishes. Garage conversions typically start around $80,000–$120,000. Detached ADUs generally range from $150,000–$300,000+. We provide detailed, transparent quotes after your free consultation — no hidden fees.
California law (AB 670) significantly limits HOA ability to block ADUs. We review your CC&Rs and advise on what's required. In most cases, HOA restrictions cannot prevent a code-compliant ADU.
Yes. Once your ADU receives a Certificate of Occupancy, you can rent it long-term. Many homeowners earn $1,500–$3,000+/month in additional rental income. ADUs also meaningfully increase your property's resale value.
Absolutely. We handle design drawings, structural engineering, permit applications, city submissions, revision responses, and all inspections. You won't need to contact the city once.
A Key Differentiator
Permits & Consulting
Most contractors build. We also navigate the full permitting process and offer consulting for homeowners who need guidance before they're ready to build.
Permit Pulling
We prepare complete permit packages — architectural drawings, structural engineering, Title 24, and all supporting documents — and submit to the city on your behalf.
Permit Expediting
Stuck in plan check? We track your permit status, respond to correction notices, and work directly with city plan checkers to get your permit approved as fast as possible.
Construction Consulting
Not sure what to build, what it costs, or who to hire? We provide honest, paid consulting sessions to help you plan your project before committing to anything.

About Mantra Builders
Your GC. Your Sub.
Your GC. Your Sub.
Your Solution.
Mantra Builders was built on something simple — do the work right, communicate honestly, and show up when you say you will. In construction, that's rarer than it should be.
Deepak Sharma didn't find his way into construction — he was built for it. In his early twenties, he earned his NCCER certification and got his hands dirty learning the trades from the ground up. That foundation led to building and operating a tenant outfit business serving the restaurant industry, which he ran for four years and sold at a profit. He then flipped multiple commercial AND residential properties, maximizing build allowances and exiting each one with strong returns — developing a sharp instinct for when and where to build, and how to make a project pencil out.
And the industry runs in his family. With two uncles who are licensed general contractors and developers — each with over 30 years of experience — and a family background deeply rooted in construction, Deepak grew up understanding the industry from every angle. Not just how to build, but how to invest, develop, and create long term value. That's the foundation Mantra Builders stands on.
Today, Mantra operates from a unique position — as a licensed General Contractor and as a trusted subcontracting partner for other builders. Homeowners receive organized, professional project leadership. Contractors gain a reliable, deadline driven finish partner. Investors get structured execution with transparent communication from permits to completion.
Our Vision
We're building more than projects — we're building a company people can count on. The goal is simple: become the Central Valley's most trusted construction and development partner by doing things the right way, every time. Transparent. Accountable. Built to last.
