Who can pull the detached adu permit on my Silver Lake project?

Alpha Dream Construction pulls every Silver Lake permit in our license (CSLB #1145233). You stay off the line as contractor of record — we handle LADBS (City of Los Angeles) plan check, corrections, and inspections through close-out.

What gets rejected most often on Silver Lake detached adu plan checks?

On Silver Lake detached adu submittals to LADBS (City of Los Angeles), the three most common rejection causes are: Incomplete Title 24 forms — most common single-issue rejection; Site plan missing setbacks, easements, or existing tree protection; Structural calcs not matching the architectural set. Catching them on day one shaves 4–8 weeks off the typical cycle.

Can I start the detached adu job before the Silver Lake permit is issued?

No — California law prohibits starting permitted work before permit issuance, and LADBS (City of Los Angeles) can issue a stop-work order plus penalty fees of 2–4× the permit cost. We schedule mobilization the same week permit issues, never before.

Does Silver Lake require a separate inspection for detached adu?

Yes — 8 inspections are typical: Setback / form-board inspection before foundation pour; Foundation rebar + post-tension inspection; Underfloor rough plumbing + electrical; Framing + shear inspection with structural observation; and final.

Is my Silver Lake property in a historic district — and does that change the detached adu permit?

Likely yes — exterior alterations on contributing structures in Silver Lake's historic overlays need design-review approval before plan check accepts the building permit. We file the historic clearance in parallel to keep schedules tight.

Full plan-check cycle (2–3 rounds of corrections is typical) — expect 6–14 weeks from submittal to issued permit. Hillside-overlay parcels need grading-quantity and haul-route sign-off. Historic-overlay parcels need design review before plan check accepts the package.

LADBS (City of Los Angeles) cannot deny a code-compliant ADU on a single-family lot and must respond within 60 days. Local ADU ordinance language may add design-review for exterior changes but cannot override the state minimums.

Estimated review timeline: 10–20 weeks to issued permit, including 2 overlay reviews plus LADBS (City of Los Angeles) plan check.
