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 Plumbing & Repipes.

LA plumbing — PEX whole-home repipes, tankless water heater conversion, sewer lateral replacement, gas line. LADBS + LADWP permits.

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.

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.
