Eastside / NELA · Cost
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
- $220–$290/sqft
- Garage / interior conversion
- $170–$230/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.

10 things we already know about this area
- HCR (Hillside Construction Regulation) blocks limit truck size to 25ft single-unit.
- Mt Washington streets above 30% grade need a haul-route permit before grading.
- Echo Park decomposed granite soil — drilled caissons over spread footings on slopes.
- Silver Lake Reservoir blocks have a view ordinance; second-story ADUs draw appeals.
- Highland Park has pre-1933 unreinforced masonry chimneys — disclose during scoping.
- BOE driveway permits in HCR take 4–6 weeks; file with plan check, not after.
- LADWP Power Hub at North Main is fastest for service-drop pickups.
- Many Eastside lots are R1.5 — duplex + ADU + JADU is a real option, not theoretical.
- Boyle Heights = Mello Act on duplex conversions; pull the file before scoping.
- Eagle Rock has narrow garages — 2-car conversions usually need a structural cripple wall fix.
