ADU Construction in Millbrae

What Is an ADU and Why Build One in Millbrae?

Accessory Dwelling Units (ADUs) — sometimes called granny flats, in-law units, or backyard cottages — have become one of the most popular ways for Millbrae homeowners to expand their living space and increase property value.

An ADU is a self-contained secondary living space built on your property. It can be detached, attached to your main home, or converted from an existing structure like a garage or basement. Designed right, an ADU provides flexibility, functionality, and long-term value — whether you use it for family, guests, or as an additional income stream.

Why ADUs are a smart investment in Millbrae:

  • Additional Living Space: Perfect for aging parents, adult children, or visiting guests — especially handy if you’re near Millbrae’s downtown or up by the hills around Magnolia Avenue.

  • Rental Income: Generate consistent income with a long-term or short-term rental — Millbrae’s proximity to SFO and BART makes it a hotspot for tenants.

  • Increased Property Value: Boost your home’s resale potential and market appeal — homes near Millbrae’s Green Hills or along El Camino Real see serious returns.

  • Multi-Generational Living: Keep family close while maintaining independence — we’ve helped folks near Millbrae’s Meadows neighborhood create space for aging parents.

  • Sustainability: Smaller footprints, energy-efficient systems, and modern materials — perfect for Millbrae’s eco-conscious homeowners.

How Cole Construction Makes It Simple for Millbrae Homeowners

We bring organization, creativity, and hands-on management to each project, ensuring your build is efficient, compliant, and visually stunning — whether you’re off Millbrae Avenue or near Taylor Boulevard.

Here’s how we make it simple and stress-free:

Millbrae Site Evaluation & Feasibility Study

Before design begins, we assess your Millbrae property to identify the best placement, size, and layout for your ADU.

  • Evaluate zoning, setbacks, and utility access — Millbrae’s rules vary by neighborhood.

  • Review city regulations and lot constraints — the hillside areas near Santa Maria Avenue have different needs.

  • Discuss potential layouts, design ideas, and budget expectations — we’ve done this for homes near Mills High School.

Outcome: A clear understanding of what’s possible for your property in Millbrae.

Custom Design & Planning for Millbrae Homes

We don’t have in-house architects, but we work closely with trusted partners to create build-ready ADU plans for Millbrae homes.

After evaluating your property near, say, Millbrae’s downtown core or out by the Millbrae Recreation Center, we collaborate with our designers and architects to develop:

  • Efficient floor plans that fit Millbrae’s lot sizes

  • Exterior designs that match your home’s style — whether it’s a mid-century ranch or modern build

  • Sustainable and energy-smart recommendations suited to Millbrae’s coastal climate

Outcome: A clear, cohesive design prepared for Millbrae’s city review and approval.

  • Full coordination with Millbrae’s city planning office — we know the team there.
