“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.
The most common custom home design mistakes in Lake Balboa are: selecting a contractor based on price alone without verifying CSLB license and insurance, approving change orders verbally rather than in writing, and starting work before permits are issued. All three create financial and legal exposure that's avoidable with careful contractor selection and contract management.
