Licensed Home Addition Contractors in Menlo Park, CA
Atlas General Construction designs and builds home additions in Menlo Park, CA, for homeowners who need more space but would rather not move. We specialize in second-story additions and also build room additions and home extensions. Every project gets a dedicated project manager as your single point of contact.
Below, we explain the types of additions we build, how our process works, and where we work across the Bay Area.
Why Menlo Park Homeowners Add Space Instead of Moving
Many of the home additions Menlo Park, CA, families plan start with a practical problem, such as needing a real home office or a bedroom for a parent who is moving in. In neighborhoods like Allied Arts, Sharon Heights, Linfield Oaks, the Willows, and Belle Haven, residents often prefer to keep their street, schools, and neighbors rather than search for a bigger house.
Your current house may already be close to your dream home and simply need more square footage. As a licensed general contractor in Menlo Park, CA, we plan each addition to match the existing rooflines, windows, and exterior materials, so the house still looks like one home decades from now.
Types of Home Additions Menlo Park, CA, Homeowners Can Choose
House additions come in several forms. The right one depends on your lot, your existing structure, and how you want to use the space.
Second-Story Addition
Building up makes sense when the yard is small or you want to keep outdoor living areas. Adding a second floor often means reinforcing the foundation, reworking load-bearing walls, and adding a staircase, so structural engineering is part of the plan from the start. Our San Mateo home expansion, for example, added about 1,000 square feet of upper-level living space and an 800-square-foot addition.
Ground-Floor Room Additions
These projects extend the home’s footprint to add a bedroom, den, or guest suite. Because the new space stays on one level, this option suits homeowners who plan to age in place.
Home Extensions and Bump-Outs
Not every project needs a full new room. A home extension pushes an exterior wall out a few feet to enlarge a living or dining area. It is a practical choice when a space feels tight, but the layout already works.
ADUs and Garage Conversions
Some families want a separate living unit instead. We build attached, detached, and junior ADUs as well as garage conversions, and our page on ADU construction in Menlo Park explains how an accessory dwelling unit project works.
What Is the Difference Between a Home Extension and an Addition?
Homeowners and home extension contractors often use the two terms interchangeably. In general, a home extension enlarges an existing room by moving a wall outward. A home addition creates new space, such as a bedroom wing or an entire second floor. Both usually involve structural work, permits, and careful tie-ins to the existing roof and walls. The main difference is scope, which affects design time, cost, and how long you live around construction. A home renovation, by contrast, updates existing rooms without adding square footage.
Our Home Construction Process From Plans to Final Walkthrough
The four stages below apply to all home additions Menlo Park, CA, residents hire us for, from a single room to a full second floor.
Consultation and Feasibility
We start with a free site visit at your Menlo Park home, which you can book by phone or through our contact form. We look at the existing structure and discuss your goals, vision, and budget. We also check your property’s zoning limits and the permits the addition will need, so planning starts from what the city allows.
Design, Engineering, and Permits
During the design process, we coordinate with architects, structural engineers, and your interior designer if you have one. Our team prepares the drawings, structural calculations, and energy compliance documents. We then manage submittals and revisions with the Menlo Park Building Division, or your local permitting agency, until permits are issued.
Building and Inspections
With permits in hand, home construction begins. Licensed professionals handle demolition, foundation work, framing, roofing, and windows, along with the plumbing, electrical, and HVAC tie-ins. We choose materials to match your existing home. Your project manager sends regular photo and video updates, and inspections take place at each milestone.
Final Walkthrough
Before closeout, we walk the finished addition with you to check craftsmanship, safety, and function, and we fix anything that needs attention. Every addition comes with a warranty, so ask for the terms when you receive your estimate.

Home Addition Questions From Menlo Park Homeowners
Should I build up or out on my Menlo Park lot?
It depends on your lot size, setbacks, and how much yard you want to keep. Larger lots, like many in Sharon Heights, often leave room to build out, while tighter Menlo Park lots usually point toward building up. We review your site early in the project so you can compare both.
Who approves addition plans in Menlo Park?
Inside city limits, addition plans go through the Menlo Park Building Division. We prepare the submittal, respond to plan check comments, and schedule inspections for you.
When is the best time to build an addition?
Design, planning, and permitting take time, so reach out several months before you want crews at your Menlo Park home. Starting design in fall or winter often lets framing and roof work happen in the drier months.
Can we live at home during construction?
Often, yes. Some clients stay in the house while we build, and our crews work to limit the disruption. When we build upward, you may prefer to stay elsewhere while the roof is open.
