Sacramento ADU Services
More living space, right on your own lot. Permit-ready plans for detached units, attached additions, garage conversions, and JADUs.
An accessory dwelling unit can turn one lot into rental income, a place for family to live nearby, or a private home office without buying a second property. Complete Drafting Services LLC designs ADUs and prepares the permit-ready drawings Sacramento homeowners need to move from idea to building department submission.
We are a residential drafting company, not a construction contractor. We design the unit and prepare accurate drawings for your licensed contractor and local building department, shaping every project around your lot, goals, and budget.
Types of ADUs We Design
From a studio above the garage to a complete detached unit, we help select and design the right ADU for your property.
Standalone backyard homes designed for privacy, with placement, setbacks, access, and utility connections coordinated around your lot.
Detached ADUs
Attached ADUs
Independent living spaces connected to the main home, with their own entrance, kitchen, bathroom, and a layout suited to tighter lots.
Garage Conversion ADUs
Existing garages redesigned as code-compliant homes with coordinated insulation, openings, electrical, plumbing, and structural requirements.
Junior ADUs
Smaller independent spaces created within the home's footprint and designed around Sacramento's specific size, access, and kitchenette requirements.
What's Included in Our ADU Design & Permit Drawings
-
A site plan showing placement, setbacks, and the relationship to the existing home.
-
Floor plans, exterior elevations, sections, and electrical plans within our drafting scope.
-
Permit-ready documents prepared for local building department review.
-
Interior layouts planned around storage, natural light, privacy, and daily use.
-
Sections, illustrating how a structure is built through a cut-away view, when required
-
Coordination with a structural engineer or Title 24 consultant when required; these services are ordered separately.
How We Collect Accurate Site Information
An ADU has to work with your lot's real dimensions, structures, and access points. We visit the property and use Matterport 3D capture technology to document the site before drafting begins.
Accurate measurements help avoid conflicts with property lines, existing utilities, and the main home once the plans enter review.
Planning Your ADU
Early decisions about rental use, family needs, unit type, bedrooms, and utilities help us create a practical layout without costly redesign later.
Sacramento-area jurisdictions apply local zoning, lot coverage, and setback rules alongside California ADU law. We account for the rules that apply to your address and can help compare custom designs with available pre-approved plans.
ADU or Living-Area Garage Conversion?
An ADU is an independent dwelling with its own kitchen, bathroom, and entrance. If you want more space for your existing household without creating a separate unit, explore our garage conversion plans.

Frequently Asked Question
Can I build an ADU on any residential lot in Sacramento? Eligibility depends on the property's zoning and existing structures. We can review your address during design, and recommend confirming current eligibility with your local building department.
Do you design detached, attached, and garage conversion ADUs? Yes. We design detached units, attached additions, garage conversions, and JADUs.
Should I use a pre-approved plan or a custom design? Pre-approved plans may review faster, while custom plans fit unusual lots and personal goals more closely. We can help you compare both options.
Do you handle construction? No. We provide design and permit drawings for a licensed contractor to build from.
Will my ADU need an engineer? Some projects do, especially detached units and conversions with major structural changes. We coordinate separately billed engineering when required.
What size ADU can I build? Maximum size depends on the lot, zoning, and ADU type. We review the property early so the proposed layout fits current requirements.
