“The detail I fight for on every custom home: a dedicated electrical subpanel for future expansion, pre-wiring for solar even if you're not installing panels yet, and a whole-house audio/video conduit run. These add $8–12K and eliminate $40–60K in future retrofit costs as technology changes.”
For hillside custom homes, specify a separate 'grading and drainage plan' as an architectural deliverable, not just an afterthought on the site plan sheet. This document shows existing contours, proposed grades, drainage flow directions, and retaining wall locations. It's the most coordination-intensive drawing set and the one most likely to have LADBS comments requiring revisions.
Most custom home design projects in Pasadena that involve structural, electrical, plumbing, or mechanical changes require LADBS permits. Working without required permits in Pasadena creates unpermitted improvement disclosure obligations at sale. Your contractor should pull all required permits before work begins — this protects both your investment and your legal standing.
Verify CSLB license at cslb.ca.gov, request 3+ references from completed custom home design projects in Pasadena or nearby, confirm active insurance and worker's comp coverage, and ensure the contractor can explain the permit process for your specific project. Contractors who know Pasadena's local conditions, permit office staff, and inspection procedures complete projects faster with fewer complications.
