AfterHow Much Does Garage Conversion Cost in Long Beach?
A garage conversion in Long Beach typically costs between $30,000 and $80,000 in 2026, depending on square footage, whether you’re adding a bathroom or kitchenette, and the condition of the existing slab and framing. Most attached garage conversions in neighborhoods like Belmont Heights, Bixby Knolls, and Los Altos land in the $45,000 to $60,000 range when you include finishes, insulation upgrades, and electrical work. A basic studio conversion without plumbing can start around $30,000, while a full ADU-grade conversion with a kitchen and bath pushes toward $80,000.
Those numbers cover design, permits, labor, and materials for a finished, livable space. We’ll break down exactly where the money goes below.

Garage Conversion Cost Breakdown (2026)
Here’s what a typical attached two-car garage conversion (roughly 400 square feet) looks like, line by line, in the Long Beach market. These are real numbers we’ve quoted repeatedly across the city.
| Line Item | Typical Range |
|---|---|
| Total project (studio, no bath) | $30,000 – $45,000 |
| Total project (one bath, no kitchen) | $40,000 – $60,000 |
| Total project (kitchenette + bath) | $55,000 – $80,000 |
| Design and architectural plans | $2,500 – $6,000 |
| Long Beach permits and fees | $1,500 – $4,500 |
| Demo and framing | $3,000 – $7,000 |
| Slab repairs / leveling | $800 – $4,000 |
| Insulation and drywall | $4,000 – $8,000 |
| Electrical (panel, wiring, fixtures) | $4,500 – $10,000 |
| Plumbing (if adding bath or wet bar) | $3,500 – $9,000 |
| HVAC (mini-split or ducted tie-in) | $3,000 – $7,500 |
| Flooring | $2,000 – $5,500 |
| Windows and door upgrades | $1,800 – $6,000 |
| Paint and finish work | $1,500 – $4,000 |
| Kitchenette (cabinets, counter, sink) | $9,000 – $20,000 |
| Bathroom addition (full) | $9,000 – $28,000 |
Those ranges are based on our actual quotes in Long Beach. A 300-square-foot single-car garage in Wrigley with a simple studio layout trends lower. A 480-square-foot two-car garage in Naples with a full bath and kitchenette trends higher, especially if you want name-brand fixtures from Kohler or Toto, which we install regularly.
One thing that surprises people: the Long Beach municipal code and the city’s parking standards can add requirements before you even swing a hammer. Depending on your neighborhood and whether your garage is attached or detached, you may need to provide a covered parking replacement or pay an in-lieu fee. We factor those into every written price, so there’s no surprise line item mid-project.
What Affects Garage Conversion Pricing in Long Beach
- Square footage and layout. A 240-square-foot single-car garage costs less than a 500-square-foot two-car. The more open space in the existing structure, the less reframing you pay for.
- Plumbing scope. Adding a bathroom or kitchenette is the single biggest cost driver. Running sewer and supply lines across a slab is real work, especially in older Long Beach homes where the main line may sit under the driveway or the rear patio.
- Permit and parking requirements. Long Beach enforces replacement parking rules for garage conversions in some zones, especially in Alamitos Beach and Belmont Shore where street parking is tight. In-lieu fees or covered parking structures add $3,000 – $15,000 depending on the requirement.
- Slab condition. Many Long Beach garages, especially in pre-1970 homes in California Heights and Lakewood Village, have settled slabs or moisture issues. Leveling and sealing can run $800 – $4,000 before finish work begins.
- Insulation and climate needs. Long Beach summers mean your converted space needs proper insulation and a cooling solution. A ductless mini-split is the standard choice for garage conversions and lands between $3,000 and $7,500 installed.
- Finish level. A rental-ready studio with builder-grade finishes costs less than a polished guest suite with Cambria quartz countertops, KraftMaid cabinetry, and Grohe fixtures. You choose the materials; we write the price before work starts.
How to Save on Garage Conversion
Garage conversion pricing is not a mystery. The biggest savings come from scope decisions made before permits are pulled, not mid-project changes. Here’s where Long Beach homeowners actually trim their budget:
- Skip the kitchenette. A kitchenette adds $9,000 – $20,000 by itself. If you’re converting the garage into a bedroom, office, or workout room, skip the plumbing and save a third of the project cost.
- Keep the existing footprint. Adding square footage means foundation work and more framing. A straight conversion of the current garage shell is always cheaper than bumping out.
- Choose a dry bar over a wet bar. If you want a coffee station or office beverage corner, run it without plumbing. You save the $3,500 – $9,000 plumbing line and the permit complexity that comes with it.
- Use the existing electrical panel if it has capacity. Some Long Beach homes have 200-amp panels with room to spare. Others need an upgrade. We’ll tell you which one you have during the estimate.
- Time your materials. We pass our trade pricing on Cambria, Caesarstone, Kohler, and Moen products directly to you. Choosing stock rather than custom sizes can save $1,000 – $3,000 on the finish package.
And the simplest save: call us before you assume a number. Our estimates are free, and you’ll get a written price with line items so you can decide what to include and what to cut. Call (562) 512-6480 and we’ll walk the space with you.
Garage Conversion vs. ADU: What’s the Difference in Long Beach Cost?
Homeowners sometimes confuse a garage conversion with an ADU (accessory dwelling unit). They’re related, but the costs are very different. A full detached ADU built from the ground up in Long Beach runs $90,000 – $220,000. A garage conversion, even a high-end one with a kitchen and bath, tops out around $80,000. That’s because the structure already exists: you have walls, a slab, and often electrical already in place.
If your goal is rental income, a garage conversion can still qualify as a junior ADU (JADU) or ADU conversion under California law, provided it meets separate entrance, kitchen, and bathroom requirements. Long Beach has streamlined ADU permitting, and our team works through those applications regularly. The cost difference between a converted garage ADU and a new-build ADU often comes down to the condition of the existing structure and whether the city requires significant seismic or parking upgrades.

Long Beach Neighborhoods We Work In
Garage conversion pricing shifts slightly from block to block because permit requirements, lot sizes, and home ages vary. We’ve completed conversions in the following Long Beach areas:
- Belmont Heights and Belmont Shore: Older homes, many with detached garages off alley access. Plumbing runs tend to be longer, which adds cost.
- Bixby Knolls and California Heights: Classic 1930s – 1950s homes, often with attached garages and solid framing. Good candidates for mid-range conversions.
- Naples and the Peninsula: Tighter lots, higher property values, and stricter design review in some pockets. Finishes trend high-end.
- Wrigley, Los Altos, and Lakewood Village: Many single-story homes with oversized garages that convert cleanly into studios or in-law suites.
- Downtown and Alamitos Beach: Older building stock with smaller garages, but many attached with direct house access, which simplifies electrical and HVAC tie-ins.
If you’re outside these names, call us anyway. Long Beach is our home, and we work across the city, including Signal Hill borderline properties and Los Alamitos-adjacent streets.

FAQs – Garage Conversion Cost
What’s the cheapest garage conversion you can do in Long Beach?
A minimal studio conversion with no plumbing, basic electrical, insulation, drywall, and laminate flooring starts around $30,000. Call (562) 512-6480 for a written quote on your specific garage.
Is a garage conversion cheaper than building an ADU in Long Beach?
Yes. A garage conversion ranges from $30,000 – $80,000, while a new detached ADU runs $90,000 – $220,000. The existing structure and slab are already paid for, which is the bulk of the savings.
How long does a garage conversion take in Long Beach?
Most garage conversions take 8 – 14 weeks from permit approval to final inspection. Projects with kitchens, baths, or significant slab work trend longer. Permitting in Long Beach typically takes 3 – 8 weeks depending on the scope and any parking-related review.

Can I convert my garage into a rental unit in Long Beach?
In many cases, yes. California law allows ADU conversions, and Long Beach has adopted state-friendly ADU standards. The conversion must meet separate entrance, bathroom, kitchen, and fire safety requirements. Budget $55,000 – $80,000 for a rental-ready unit with a bath and kitchenette.
What adds the most cost to a Long Beach garage conversion?
