Our Process of Converting Your Garage

Step 1: Planning & Permits

We start by looking at your garage to see what is possible. We listen to your ideas and needs, then create a plan that uses the space well and meets all the local rules.

We fill out and submit all the paperwork for permits.

Step 2: Building Prep

After permits are ready, we remove anything that is not needed and make sure the garage is strong enough to be a living space.

We build new walls, doors, and windows as needed, and add insulation to keep the space comfortable.

Step 3: Finalization

We put in all the wiring, plumbing, and heating or cooling systems. Then we finish the inside with drywall, floors, paint, cabinets, counters, and fixtures to make the space feel like home.

After passing inspections, we show you the finished space. Your new ADU is ready to use or rent out right away.

Frequently Asked Questions

How much does a garage conversion ADU cost in Sacramento?

In Sacramento County, garage conversion ADU costs typically range from $90,000 to $150,000, depending on the size, condition of the existing structure, and level of finishes. This is significantly less than building a new detached ADU, which can cost $200,000 or more. Factors that affect pricing include:

Foundation work required (if any)
Utility connections and upgrades
Interior finish quality (standard vs. premium)
Additional features like separate HVAC systems
Permit fees (which vary by jurisdiction within Sacramento County)

We provide detailed, transparent quotes after a thorough site inspection to ensure there are no surprises during your project.

How long does it take to convert a garage into an ADU?

The typical timeline for a garage conversion ADU in Sacramento County is 4-6 months from initial consultation to completion. This breaks down approximately as:

Design and engineering: 3-4 weeks
Permitting: 6-10 weeks (varies by jurisdiction)
Construction: 8-12 weeks

Timelines can vary based on the complexity of the project, local permitting backlogs, and any unforeseen conditions discovered during construction. Our team works efficiently to minimize disruptions and complete your project as quickly as possible while maintaining quality standards.

Can I convert my garage and still have a place to park?

Yes, there are several options for maintaining parking after a garage conversion:

Create a new parking pad or carport elsewhere on your property
Convert only part of a multi-car garage, preserving some covered parking
Utilize existing driveway space for uncovered parking

Under California ADU laws, replacement parking is generally not required when converting a garage to an ADU. However, we can help you plan for practical parking solutions that work for your specific property and needs in Sacramento County.

Do I need a separate address for my garage conversion ADU?

In Sacramento County, ADUs typically share the same address as the primary residence but with a unit designation (e.g., 123 Main Street Unit B). For mail delivery and emergency services, this separate unit designation is important. We can assist with the process of registering your ADU with the appropriate local authorities and postal service to ensure proper addressing.

If you plan to rent out your ADU or use it for a home-based business, having a clear unit designation becomes even more important for legal and practical purposes.

What are the main zoning and permit requirements for a garage conversion?

Sacramento County has specific requirements for garage conversion ADUs, including:

The property must be zoned for residential use
The existing garage must be legally permitted
The ADU must include a kitchen, bathroom, and living area
Minimum ceiling height of 7 feet
Compliance with energy efficiency standards (Title 24)
Proper egress windows and fire safety features
Separate entrance from the main dwelling

Our team stays current with all local regulations and handles the entire permitting process, ensuring your conversion meets all requirements.

Yes, we can. Our team has extensive experience addressing the textured walls frequently found in Sacramento’s diverse housing stock.

How much rental income can I expect from a garage ADU in this area?

In Sacramento County, garage conversion ADUs typically generate the following monthly rental income:

Studio ADU: $1,000 – $1,300
One-bedroom ADU: $1,300 – $1,800
Premium locations or high-end finishes can command even higher rents

This represents a potential annual income of $12,000 – $21,600, providing an excellent return on investment. Many of our clients see complete ROI within 5-7 years, after which the ADU continues to generate positive cash flow and increase overall property value.
