Design inspirationNew Garage Addition
A brand-new two- or three-car garage, matched to your home — permit-ready for a future above-garage ADU.
New Garage Addition across Greater Los Angeles.
Whether you're replacing a tired old garage, adding covered parking where none existed, or laying the groundwork for a future above-garage ADU, a new garage is one of the smartest structural investments you can make in your home.
Every HomeAdd garage is built to match the main house — same stucco, same trim, same roofline — and pre-configured with the electrical panel capacity, plumbing rough-in, and foundation depth that a future second-story ADU will need. Do the hard part once.
Typical footprints are 400–720 sq ft.
Common new garage addition options.
Two-car detached garage
The classic — 20x20 or 22x22 footprint, set back from the main house per city rules.
Three-car detached garage
22x30 to 24x36 — for households with three drivers or a workshop bay.
Attached two-car garage
Shares a wall with the house — often includes a mudroom entry from the garage.
Garage + workshop
One car bay plus a full workshop with 220V outlets, upgraded ventilation, and epoxy floor.
Garage + storage loft
Add pull-down or fixed stair access to an attic-height storage loft above.
ADU-ready garage
Reinforced foundation, tall walls, upsized electrical panel, and stub plumbing so a future above-garage ADU is a straight shot.

Planning ranges (Los Angeles & Ventura)
Preliminary planning ranges vary by jurisdiction, site conditions, design, utilities, and finish level. A written proposal follows feasibility and design.
Standard build, matched exterior, standard doors.
Larger footprint, three doors, upgraded electrical.
Upsized foundation, tall walls, upsized panel, stubbed plumbing — planning for a future ADU now usually costs less than retrofitting later.
Filed, corrected, inspected — by us.
We prepare and submit the permit package to the department that reviews your address, whether that is LADBS, LA County, Ventura County, or a city building department in Los Angeles or Ventura County. You never touch a portal, sit on hold, or drive to a counter.
- Residential building permit
- Structural plan check
- Grading / drainage (as required)
- Electrical permit (sub-panel + circuits)
- Plumbing permit (for ADU-ready stubs)
- Driveway approach permit
- Setback / lot-coverage verification
- Final building inspection

Is it worth building ADU-ready?+
Often, yes. Planning for a future ADU during design — structure, utilities and stairs — usually costs less than retrofitting an existing garage later. The written proposal prices it both ways so you can decide.
How far from the property line can it be?+
Setbacks depend on zoning, lot conditions and any applicable overlays. We review the parcel during feasibility and confirm requirements before design.
Can I convert my old garage instead?+
Often yes — see our garage conversion page. But if the existing garage is undersized, damaged, or you want two functions (parking + ADU), a new build usually wins.
Do I need to keep off-street parking?+
For most single-family lots in LA, yes — the city wants covered or off-street parking preserved. A new garage satisfies that requirement even if you later convert the original garage into an ADU.
Can we include an EV charger?+
Yes. We size the panel and install a NEMA 14-50 or hardwired Level 2 charger as part of the electrical scope. Included as a line item.
How much does driveway work add?+
It depends on the scope, from a small apron replacement to a full new driveway; it's itemized in the proposal.
Other ways to grow your home.
One more bedroom, an office, a nursery — added to your existing footprint.
Second stories, full wings, kitchen expansions — significant square footage.
Double your square footage without touching the yard — a full second floor built above your existing home.
A kitchen addition bumps out the back of the house, takes down the wall, and makes the kitchen the heart of the home.
A private new primary bedroom, walk-in closet, and spa bath — added to your existing home.
Bigger living space with vaulted ceilings, a fireplace, and doors that open to the yard.
