Q: What happens after the Action Plan?
We move into full design-build services, starting with schematic design and progressing through construction drawings and permitting.
This includes architectural design, consultant coordination, interior design, and preparing all documentation for construction.
Q: What’s included in Letter Four’s interior design services?
We help with all permanent finishes (tile, lighting, cabinetry, etc.) and can also assist with furnishings.
Interior design is included in our scope and billed hourly, so you can scale our support to your needs.
Q: When does the interior design team get involved?
Typically in the Design Development phase, continuing through construction for seamless coordination.
Q: How long does it take to get permits for a custom home in Los Angeles?
Simple projects may receive permits in 3–4 months; complex ones can take a year or more.
Factors include HOA approvals, design review boards, Coastal Commission, stormwater requirements, and LADWP or grading permits. Our Project Planning Pack outlines what to expect.
Q: What factors can affect how long it takes to design and build my custom home?
Timelines vary, but the biggest factors are site conditions, scope changes, required approvals, and how quickly decisions are made.
Quick decision-making keeps momentum steady, while mid-project changes can add weeks or even months. Complex sites with slopes or challenging soils often take longer to engineer and permit. Special approvals — such as HOAs, the Coastal Commission, or Historic Review boards — can extend timelines by 2–6 months. Even seasonality matters: starting in spring or summer usually allows for faster progress than beginning in the winter.
At Letter Four, we build these considerations into your project roadmap from the start, so you know what to expect and can plan with confidence.
