Looking to create additional living space without breaking the bank? Garage conversions are the fastest, most affordable way to build an ADU in California. These transformations turn existing structures into legal rental units while maximizing your property's earning potential.
Why Garage Conversions Make Sense
Converting your garage offers significant advantages over building from scratch. The foundation, walls, and roof already exist—cutting construction costs nearly in half compared to new detached units. Many homeowners find garage conversions pay for themselves within 3-5 years through rental income.
The Permitting Process Made Simple
While contractors excel at construction, the permitting process trips up many garage conversion projects. California's regulations are specific about what constitutes a legal living space. Common requirements include:
Minimum ceiling heights
Proper insulation and energy efficiency
Adequate windows for light and egress
Updated electrical systems to handle residential demands
Fire safety features
At All Cal Construction, we specialize in navigating these requirements with a 100% permit approval record. We never submit plans that won't get approved, saving you time and preventing costly revisions.
Converting Without Compromising
The best garage conversions maintain the character of your home while creating a completely independent living space. Smart design can incorporate separate entrances, sound insulation, and privacy features that benefit both you and your future tenants.
