Our In-House Garage Conversion Process


3D Architectural Design & Permitting
You shouldn't have to guess what your final space will look like. We start with precision 3D architectural rendering and detailed floor plans. From there, our team navigates the entire City of Sacramento permitting process on your behalf, ensuring rapid approval for both structural and Title 24 energy requirements.

Structural & Utility Engineering
A true ADU requires independent, heavy-duty utility infrastructure. Whether it involves upgrading your main electrical service, trenching new underground lines to meet SMUD requirements, or installing independent mini-split HVAC systems, we build structures engineered for modern, code-compliant living.

Premium Interior Finishes
As a high-end design-build firm, we never settle for basic contractor-grade materials. Every GBG Construction Inc. conversion features premium touches that maximize your appraisal value—think frameless glass shower enclosures, level-5 drywall finishes, custom cabinetry, and architectural LED lighting.
Why Convert Your Sacramento Garage?
-
Passive Rental Income: The Sacramento housing market is fiercely competitive. Transforming your garage into a premium 1-bedroom or studio ADU creates an immediate, highly desirable rental unit that can generate consistent monthly cash flow.
-
Multi-Generational Living: Keep your family close while maintaining total privacy. A garage conversion is the perfect way to build a luxurious, fully independent suite for aging parents or adult children without sacrificing your backyard footprint.
-
Massive Property Value Equity: This isn't just a remodel; it is an addition of legal, livable square footage. A fully permitted, high-end ADU adds immediate and aggressive equity to your main property appraisal.

Frequently Asked Questions: Sacramento ADUs
(Q1) How much does a garage-to-ADU conversion cost in Sacramento?
Answer: A proper, fully permitted garage conversion is essentially building a new, independent home. Costs vary based on your existing foundation, required utility trenching, and finish materials. In the Greater Sacramento area, a high-end, turnkey conversion typically ranges between $90,000 and $130,000+. We focus strictly on premium builds that maximize your property's appraisal value. Use our interactive CostHammer tool above to run a baseline estimate for your specific footprint.
(Q2) How long does the garage conversion process take?
Answer: The entire process usually takes 4 to 6 months. This is split into two phases: Architectural Design & Permitting (which takes about 4 to 8 weeks depending on the city's backlog) and the physical construction phase (which typically takes 3 to 4 months). Because we manage the build entirely in-house, we eliminate the delays caused by waiting on multiple sub-contractors.
(Q3) Do I need a permit to convert my garage into a living space?
Answer: Absolutely. Attempting an unpermitted garage conversion is a massive liability and will not add legal square footage to your home's value. We handle the entire permitting process for you, including architectural drafting, structural engineering, and strict California Title 24 energy compliance.
(Q4) How are utilities handled? Do I need a separate SMUD meter?
Answer: Utility coordination is where inexperienced contractors make expensive mistakes. Depending on your property's current electrical load and local utility rules, we will either run a sub-panel from your main house or coordinate directly with SMUD to install an upgraded Triplex panel or trench new underground lines. We handle all load calculations to ensure your new ADU is fully powered and up to code.
