What an ADU costs in Eastside / NELA

Honest 2026 pricing for Eastside / NELA ADU projects. These ranges are installed cost — design, permit, construction, and standard finishes — based on jobs we've actually closed in this market.

Installed cost ranges

Detached new-build: $450–$600/sqft
Garage / interior conversion: $260–$380/sqft

Why Eastside / NELA prices look like this

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.

How to read these numbers

These are total installed $/sqft, not just construction. The detached range assumes a clean 600–900 sqft new-build with mid-range finishes. Conversions price lower because the shell already exists — most cost lives in plumbing, electrical, and the kitchen. Move outside these ranges and we'll tell you why before you sign anything.
