Home Additions
Design by M&M helps Saratoga homeowners create more functional living space through carefully planned room additions. As a design-build contractor serving Saratoga, San Mateo County, and the greater Bay Area, we manage the entire process — from early design and feasibility through permitting, construction, and final walkthrough.
On an Saratoga property, an addition is rarely just about square footage — it’s about how the home functions as a whole. As an experienced room addition contractor, Design by M&M helps homeowners expand your living space in a way that complements the existing architecture and takes full advantage of the lot.
Common addition projects we take on in Saratoga include:
- Rear additions — expanding living, kitchen, and entertaining spaces toward the garden and outdoor areas
- Primary suite additions — creating a true retreat with the space Saratoga lots allow
- Second story additions — adding an upper level within the city’s height limits and objective design standards
- Side additions — extending wings for guest quarters, offices, or family space where setbacks allow
- Full-home expansion projects — comprehensive additions that rework the entire footprint
Accessory Dwelling Units (ADU)
Saratoga’s larger lots make it well suited to detached ADUs and guest houses — whether for extended family, long-term guests, an adult child, or rental income. Detached units up to 1,200 square feet are permitted on most single-family lots with four-foot side and rear setbacks. As an experienced ADU builder in Saratoga, Design by M&M guides homeowners through every stage, from confirming what the lot can support to final inspection.
We design and build all types of ADUs, including:
- Detached ADUs and guest houses — standalone units designed to complement the main residence and landscape
- Attached ADUs — connected living quarters with independent access and privacy
- Junior ADUs and in-law suites — self-contained space within the existing home, ideal for multigenerational living
Saratoga processes ADU permits ministerially, with the state’s 60-day decision deadline, and no replacement parking is required when converting a garage or carport. On larger and hillside parcels the real planning work is elsewhere — siting, utility runs across the lot, protected trees, grading, and geotechnical clearance where the property sits in a landslide or liquefaction area. We handle that groundwork so the project moves forward with clarity instead of guesswork.
Garage Conversions
We specialize in turning underused garages and outbuildings into comfortable, fully permitted living space. Serving Saratoga and nearby communities, our team helps homeowners expand what their property can do — without adding new structures to the lot.
Popular garage conversion projects include:
- Converting a detached garage to an ADU or guest quarters
- Creating a home office, studio, or gym
- Transforming an outbuilding into flexible bonus space
Garage conversions often look simple from the outside, but they involve real construction and compliance work: insulation, electrical upgrades, plumbing (for ADU conversions), egress requirements, and city permitting. We manage those details from the start, so the finished space is safe, legal, and built to the same standard as the main home.
Design Build
Design by M&M is a design build contractor, which means one team manages your project from concept to completion. Instead of coordinating separate architects, designers, engineers, and builders, you work with a single team responsible for the entire outcome.
Our design-build approach includes:
- Consultation and property review
- Custom designs shaped around your goals, property, and budget
- Architectural planning and engineering coordination
- Town permitting and approvals
- Construction scheduling and project management
- The build phase, through final walkthrough
Saratoga gives you three possible review paths, and which one you land on is decided by the design itself. Projects meeting the city’s objective design standards can go through administrative ministerial review — staff level, non-discretionary — provided you complete the Objective Design Standards Checklist and notify adjacent neighbors before submittal. Projects that miss those standards fall to discretionary administrative design review, and larger or more sensitive ones go to the Planning Commission. The difference between paths is months. Designing to the checklist from the start is what keeps a project on the fastest one, and when one team owns both design and building, nothing gets lost between the drawing and the finished result.
Home Remodeling
As a remodeling company serving Saratoga, we focus on substantial renovation projects that bring established homes up to modern standards of comfort, efficiency, and function. Saratoga splits between single-story ranch homes on generous flatland lots and larger properties in the western foothills, and both often reach a point where the layout no longer fits the household — dated floor plans, aging systems, and finishes that no longer reflect the home’s value.
Our remodeling services include:
- Whole house renovation — comprehensive updates to layout, systems, and finishes across the residence
- Kitchen remodels — typically as part of larger layout improvements or expansions of the home’s main living areas
- Major renovations — reworking floor plans, modernizing structural and mechanical systems, and restoring older homes to their potential
- Renovation paired with additions — improving the existing home while expanding its footprint
Our remodeling process follows the same design-build structure as our additions and ADU work: feasibility first, then design, budget alignment, permitting, and construction — all managed by one team with clear communication throughout.
