FAQ

  • What is a garage conversion, and how can it benefit me?

    A garage conversion transforms an unused garage into a functional living space such as a home office, guest suite, rental unit (ADU), gym, or studio. It’s a great way to add value and usable square footage to your home without major expansion.

  • What’s included when Dream Build Services handles my conversion?

    We manage everything—design, permits, insulation, electrical and plumbing upgrades, energy-efficient improvements, and final inspections. You’ll have one team from concept to completion.

  • Do I need a permit for a garage conversion in Fremont or the East Bay?

    Yes. We handle all permits and zoning requirements to ensure your conversion meets California’s building and energy standards.

  • How long does a typical garage conversion take?

    A basic conversion may take just a few weeks. A full ADU or suite with plumbing and a kitchen can take 2–4 months. We’ll provide a realistic timeline during your consultation.

  • What types of spaces can I convert my garage into?

    Common options include guest or in-law suites, rental units, home offices, creative studios, or gyms. We’ll help you design the perfect fit for your property and lifestyle.


  • Will a garage conversion increase my home’s value?

    Yes. Conversions add living space and can significantly boost resale value or generate rental income.

  • What happens to my parking space?

    Some homeowners retain part of their garage for storage or partial parking, while others fully convert it. We’ll review your options and ensure compliance with local parking regulations.

  • How do you make the space comfortable year-round?

    We add insulation, install new windows and doors, and upgrade HVAC systems, often with efficient mini-splits, to keep your new space comfortable in any season.

  • What affects the cost of a garage conversion?

    Key factors include plumbing, electrical upgrades, insulation, finishes, and design complexity. For an accurate quote, give us a call at (510) 916-8035 or request an estimate online.
