Feb 20257 min read

Many homeowners in Los Angeles are surprised to learn that they need a permit to convert their garage into a living space. The cost of the permit can also be significant, running anywhere from a few hundred to a few thousand dollars. Here’s a clear look at the garage conversion permit process in Los Angeles — and what you can expect to pay.

Turning your ADU garage conversion ideas into reality

If you’re considering a garage conversion, our professionals are here to listen to your ideas and offer sound advice on the best options for achieving your desired outcome — an extra bedroom, a bathroom, additional rental space, or whatever custom layout you can dream up.

Transform your garage from a disused, narrow space into an expansive multipurpose room with plenty of potential.

ADUs (accessory dwelling units) are one option when converting a garage, but you can also make the most of the space by reworking it into part of an existing room or giving it its own special purpose.

With clever interior design and a few alterations for structural support, your redesigned ex-garage could be exactly what you need to maximize the value and usability of this valuable asset.

Building codes matter

At Preferred Home Builders we stay up to date on building codes. Not only can we secure the proper permits for your ADU, we’re known for being excellent communicators with our clients.

We know a simple garage conversion is a big deal for a homeowner, especially if it’s your first time. Let us know if you want new floor space — we can make that happen too.

Depending on how your garage is converted, you’ll most likely need to install a mini-split HVAC system. If you’re looking for a preferred home builder in Los Angeles, keep in mind you’re getting the best: licensed general contractors who understand ADUs. Don’t settle for anything less than someone trained and experienced in garage conversion work.

Preferred Home Builders are knowledgeable

Unlicensed contractors or handymen simply won’t do — they can become a liability. When it comes to transforming your garage into something new, accuracy and precision are paramount, so entrust the job to someone certified in the region.

Before you choose a garage remodeling company, make sure they have prior experience building ADUs or converting garages. With that in mind, you can feel confident you’ve chosen the right remodeler for your project.

Garage conversion costs & ideas

When it comes to the cost of your garage remodel, a few factors affect the price. Your contractor may charge by the hour, have set labor fees for specific tasks, or offer a flat rate for the whole project. Costs also vary with the materials used and the size of your ADU. Reach out to us at (818) 312-6622.

Your plans could take anywhere from two weeks to several months for approval, depending on the city’s backlog. Rather than trying to steer the project solo and subcontract the labor yourself, we’d strongly recommend against that approach. On the surface it can look cheaper up front, but the final price tag is usually much higher once you account for all the time and energy spent getting it over the line.

Garage conversion projects can get complex

You may have everything you need to understand the cost of a garage conversion, but it still won’t be enough for your designer. In most cities, your plans have to include precise details for the electrical system, plumbing, and HVAC. With more accurate material specifications in place, contractors can give you better-informed pricing.

The process of garage conversions

In Los Angeles, one of the first steps in converting a garage into an ADU is obtaining a permit. Depending on the project, you may need permits from the city or county for construction, zoning, and building inspections. Make the right call and contact Preferred Home Builders for your garage conversion.
