How much does a garage conversion cost in Los Angeles?

Most LA garage-to-ADU conversions land between $160K and $260K all-in. The slab, panel, and roof condition are the three biggest swing factors.

Do I need to keep parking when I convert my garage?

Under state ADU law, most LA jurisdictions cannot require replacement parking when you convert a garage to an ADU. Transit-proximity and historic district overlays can change this — we confirm in the feasibility note.

Is my Highland Park / Angelino Heights house in an HPOZ?

Most of historic Highland Park (along Figueroa) and all of Angelino Heights are designated HPOZs. We pull the parcel against the City of LA HPOZ map during the first site walk.

Do I need a hillside permit in Silver Lake?

Many Silver Lake blocks fall inside the Hillside Construction Regulation overlay. If yours does, we add a haul-route permit and stricter truck-size limits to the schedule.

Eastside / NELA Garage Conversion.

Converting an existing garage into a legal, comfortable living unit is the fastest path to an ADU in Los Angeles. State law strongly favors it, most LA jurisdictions allow it as-of-right, and we run the whole project — confirm feasibility, plans, LADBS permit, structural upgrade, finishes — under one contract.

NELA permits are predictable as long as you're outside an HPOZ. Inside one (Highland Park, Angelino Heights, parts of Eagle Rock), the Office of Historic Resources reviews materials, windows, and street-facing changes before LADBS will issue. Hillside parcels add a separate haul-route permit and a tighter grading review.

Eastside / NELA cost band — 2026

$160K – $260K all-in

Slab condition, panel capacity, and whether the roof structure can stay determine the bottom of the band.

Eastside / NELA permit clock

8–12 weeks ministerial

Plan on 2–3 months for design + LADBS permit, then 3–4 months on-site for a typical 400 sqft conversion.

Scope — start to keys.

Slab and foundation inspection, structural upgrade scope
Wall framing, roof tie-in, fire separation per CBC
Full MEP — panel/sub-panel, plumbing rough, HVAC mini-split
Insulation, drywall, kitchen + bath buildout, finishes
LADBS or local permit submittal and inspections

What changes about the permit here.

Office of Historic Resources (OHR) review on HPOZ parcels — adds 4–8 weeks before LADBS submittal.
Hillside Construction Regulation (HCR) permits required in many Silver Lake / Echo Park / Mt Washington blocks.
Pre-1978 housing presumed to have lead paint; abatement budgeted before demo on any wall removal.
BHO (Baseline Hillside Ordinance) caps height and grading on R1H lots.

What moves the Eastside / NELA number.

Hillside parcels add $40–120k in geotech, retaining, and crane access vs flat lots.
HPOZ design review pushes window/door budgets 20–35% higher (true-divided lite, wood sash).
Lead and asbestos abatement on pre-1978 homes commonly $8–25k.
Tight street access in Silver Lake / Echo Park drives concrete pump and small-equipment days.

In short.
