📝 Permits for ADU Construction in Burlingame – What You Should Know

While the State of California has streamlined ADU approvals, each city—including Burlingame—has its own local codes and development standards. Fortunately, Royalty Builders is experienced in navigating the City of Burlingame’s permit process and will handle every step on your behalf.

Here’s how the ADU permit process works in Burlingame:

🔹 Zoning & Planning Review
We confirm that your property qualifies for an ADU under Burlingame’s municipal code, including minimum setbacks, height limits, floor area ratio (FAR), and lot coverage.

🔹 Architectural Design Compliance
Burlingame may require that your ADU match the aesthetic style of your existing home and neighborhood. We design accordingly and submit all renderings for review.

🔹 Permit Submittal
We prepare and submit a full application package including:

• Site plan

• Floor plan and elevations

• Title 24 energy compliance

• Structural engineering documents

🔹 Plan Check and Revisions
City officials may request clarifications or changes. We respond promptly and adjust plans as needed.

🔹 Building Permit Approval & Inspections
Once permits are issued, we begin construction. We schedule and manage all required inspections and ensure your ADU passes each stage.

🔹 Final Approval & Certificate of Occupancy
After a final inspection, we secure your certificate—so your unit is fully legal and ready for use.

✅ Good to know:

• Most lots in Burlingame are eligible for one ADU and one JADU
