Eastside / NELA · FAQ
Eastside / NELA ADU questions, answered
Questions we get on almost every Eastside / NELA site walk. If yours isn't here, ask us — we answer everything before you commit.
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.
Can I convert a basement or garage in NELA?
Yes — JADU rules allow up to 500 sqft inside the existing footprint, and an attached ADU can run larger. Conversions are the fastest permit path on the Eastside.
What about the legal-but-undocumented unit on my lot?
Common in NELA. State SB-1211 lets us legalize many of these as part of the ADU permit, often without bringing the entire structure to current code.
Will an ADU trigger a property tax reassessment?
California reassesses only the new construction, not the underlying property. Your existing Prop 13 base stays intact.

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.
