The Sherman Oaks ADU Permit Process — 7 Steps
- Step 1 — Scoping + FeasibilityNPLD walks your ADU scope, photographs existing conditions, pulls your parcel's zoning + overlay status (R1 vs RD, BHO, VHFHSZ, HPOZ, Coastal), and confirms what permit(s) you'll need. Free, on-site, no obligation. Sherman Oaks-specific: the Baseline Hillside Ordinance.
- Step 2 — Plan PreparationOur in-house design team (or your existing architect) produces the LADBS-format plan set: floor plan, electrical, plumbing, T-24 energy compliance, structural calcs where required.
- Step 3 — Filing with LADBSNPLD files the application — plans, energy compliance, applicant info, owner authorization — with LADBS.
- Step 4 — Plan Check + CorrectionsPlan check round 1 takes 2–5 weeks. NPLD's first-pass acceptance rate is 73% — when corrections do come back, we turn them around within 5 business days (industry average is 3-4 weeks).
- Step 5 — Permit Issuance + Fee PaymentOnce all corrections are signed off, LADBS issues the permit. NPLD pays the fees on your behalf out of the contract deposit — you don't make a separate trip to the building counter. Permit card goes on the job site for inspectors.
- Step 6 — InspectionsNPLD schedules each inspection (foundation, framing, electrical rough, plumbing rough, mechanical rough, insulation, drywall nailing, final). Inspectors are typically next-day or 2-day schedule. We're on-site for every inspection — you don't have to take time off work.
- Step 7 — Final Sign-Off + Certificate of Occupancy (if applicable)After final inspection passes, LADBS issues a final sign-off (or Certificate of Occupancy for ADU/room addition work that adds habitable sq ft). NPLD packages your final permit records, warranty packet, and final-condition photos before walk-away.
Most Common Plan-Check Rejections on ADU Projects in Sherman Oaks
These are the corrections NPLD sees most often when reviewing competitors' plans before takeover. Every one of them adds 2–6 weeks to your timeline.
- Setback non-compliance — detached ADU under 800 sq ft is 4 ft side/rear, but plans show under that
- Fire sprinkler omission when primary residence is sprinklered (CRC R313 — ADU inherits the requirement)
- Owner-occupancy declaration missing for SB-9 / SB-1069 ADU pathways
- T-24 energy compliance form not signed by HERS rater (mandatory for new conditioned sq ft)
- Utility easement / sewer lateral capacity letter from LADWP not attached
- Parking replacement waiver not asserted on plans (state law waives parking — must be cited)
- Slope-based FAR calculation not shown on plan — required under the Baseline Hillside Ordinance (or local equivalent) for any parcel with >15% average natural slope.
How NPLD Handles Your Sherman Oaks ADU Permit
We pull every permit in our contractor name (CSLB License #1105249) at no additional fee for build clients. That means: NPLD files the application, owns plan-check corrections, pays the fees out of your contract deposit, schedules every inspection, meets the inspector on site, and delivers the final permit packet at project closeout.
Why this matters in Sherman Oaks: Sherman Oaks is bisected by Ventura Boulevard. North of the boulevard, most parcels are flat R1 or RD-zoned with standard LADBS process. South of the boulevard (Royal Oaks, Longridge, Valley Vista) the Baseline Hillside Ordinance applies — expect slope-based FAR caps and a haul-route plan. Multi-family (2+ unit) parcels also trigger Rent Stabilization Ordinance (RSO) review on additions.

ADU Construction Portfolio
“ADUs in LA run $180K-$320K all-in for a 600-800 sq ft detached unit. A garage conversion to JADU is $100K-$200K. The variance comes from foundation type, utility separation, kitchen tier, and whether you use LA's pre-approved standard plans (which save 60-90 days on permits but constrain design). The number you read on Reddit — '$100K for an ADU' — usually leaves out site work, utility upgrades, and permits.”
Most ADU permit cost estimates in Sherman Oaks undershoot by 30-50% because contractors quote only LADBS fees, not the full Title 24 CF1R/CF2R/CF3R energy package ($1,200-$2,800), plan-check corrections ($400-$1,200 per cycle), or the school-district + transportation impact fees triggered above 700 sq ft. Real all-in permit cost: $4,500-$11,000 for a typical ADU. Solution: demand a line-item permit-fee breakdown at contract — not a single "permits & fees" lump sum. Anyone refusing to itemize is hiding back-end markup. We file in our CSLB name (#1105249) at no extra fee for build clients.
