ADU Construction in Menlo Park
Atlas General Construction (CSLB #1059664) is Menlo Park’s local ADU specialist. With our office at 101 Jefferson Drive, we provide faster response, deeper local knowledge, and an established relationship with the Menlo Park Community Development Department than any out-of-area contractor can offer.
We build detached ADUs, attached ADUs, junior ADUs (JADUs), and garage conversions throughout Menlo Park — from Allied Arts and Sharon Heights to West Menlo Park and the Willows neighborhood.
ADU Types We Build in Menlo Park
Detached ADU: A fully independent structure in your backyard. Up to 1,200 sq ft. Most popular in Sharon Heights and Allied Arts where lot sizes support freestanding construction.
Attached ADU: An addition to your existing home with a separate entrance. Ideal for homes without garage conversion potential.
Garage Conversion ADU: Transform your existing attached or detached garage into a livable unit. No new foundation required — fastest path to occupancy.
Junior ADU (JADU): Up to 500 sq ft within your existing home footprint. Minimal construction cost, fastest permit timeline.
The Menlo Park ADU Process
Step 1 — Feasibility: We assess your lot, existing structures, setbacks, and zoning to determine your ADU options and estimated costs.
Step 2 — Design: Our architectural partners produce permit-ready plans tailored to Menlo Park’s requirements.
Step 3 — Permits: We submit to the Menlo Park Community Development Department, respond to plan check comments, and manage the full approval process.
Step 4 — Construction: Our licensed crew builds your ADU with milestone inspections and daily project updates.
Step 5 — Certificate of Occupancy: We manage final inspections and deliver your completed ADU ready to rent or use.
Typical timeline: 6–10 months. Typical cost: $250,000–$450,000 depending on size and finishes.
Why Add an ADU in Menlo Park?
Menlo Park’s rental market is among the strongest on the Peninsula, driven by proximity to Stanford, major tech employers, and Sand Hill Road. A well-built ADU in Menlo Park can generate $3,500–$6,000/month in rental income, providing an exceptional return on investment.
Additionally, ADUs increase your property’s appraised value — typically adding 80–100% of construction cost in value appreciation in the Menlo Park market.
