One of the Most Cost-Effective Ways to Add Space.
Garage conversions are among the most affordable ways to add livable square footage or rental income to your property. California law prohibits cities from requiring replacement parking when a garage is converted to an ADU or JADU if the property is within half a mile of public transit. We've completed hundreds of garage conversion plan sets across Sacramento-area counties — we know what works, what building departments look for, and how to get your project approved.
California Law Expertise
We know the state ADU and JADU laws that protect your right to convert — and we use them to prevent unnecessary requirements from local jurisdictions.
Practical Design
Years of hands-on construction experience means our conversion plans are designed to be built efficiently — with realistic framing, insulation, and utility layouts.
Clear Timeline
The architectural phase takes 5–10 business days. We send preliminary plans for your review first — your feedback and approval speed is the biggest factor in total timeline. Most garage conversions don't require a structural engineer, so plans are typically ready to submit to the building department after the architectural phase.
Permit Coordination Included
We can manage the full permit process — submittal, plan check response, and approval — so you don't have to deal with the building department.
How It Works
Site Review
We review your garage dimensions, existing structure, and conversion goals. We confirm scope, applicable state law protections, and provide a quote.
Design & Layout
We develop the interior layout — bedroom, bathroom, kitchen/kitchenette placement — and confirm the design with you before proceeding.
Construction Documents
Complete plan set including floor plan, elevations, sections, and energy compliance documentation.
Permit Submittal
We submit to your building department and manage the review until your permit is issued.
What's Included
- Site plan showing conversion scope and setbacks
- Floor plan with dimensions, room labels, and fixture locations
- Exterior elevations showing new windows, doors, and finishes
- Cross-section through conversion area
- Title 24 energy compliance documentation
- General notes and code compliance sheet
Priced on the total square footage of the existing home — not just the garage. We must draw the full existing home (all floors, all rooms, site plan) plus the proposed conversion. This fee covers the architectural plan set only. Minimum project fees apply.
The architectural phase takes 5–10 business days. We send preliminary plans for your review first — your feedback and approval speed is the biggest factor in total timeline. If no structural engineer is needed, plans are ready to submit after architecture is complete. If structural work is required, expect 10–30 business days total. No solar or fire sprinkler design required for garage conversions.
Architect / Engineer: Structural engineering ($2,000–$4,000) is typically not required for standard single-story garage conversions. It may be required if significant structural modifications are needed — we'll advise you upfront. If required, it adds 10–30 business days total to the project timeline. The structural engineer works from the completed architectural plans and their fee is separate.
