Budgeting benchmarks for kitchen and bathroom remodels.
Expanding your home is often smarter than moving. Parrish Construction Inc. is a NARI award-winning general contractor specializing in home additions in Sacramento, CA and the greater Sacramento area — including Carmichael, Granite Bay, El Dorado Hills, Folsom, and Roseville. From bump-outs and garage conversions to full room additions, ADUs, and second story expansions, we manage every phase of the build — design, engineering, permits, construction, and finish — so the addition feels like it was always part of the house.
Home addition costs are highly scope and site-specific — a bump-out and a second story addition are very different projects. The ranges below reflect typical scopes to give you a realistic order of magnitude before your consultation.
Pricing varies based on square footage, structural requirements, site conditions, and finish selections. These ranges reflect typical Sacramento-area projects — your estimate will be tailored to your specific scope.
Targeted expansion — more space without a full addition footprint
Starting at
$40,000 – $90,000
Estimated Duration: 3–5 months
Pricing reflects standard bump-out scope on an accessible lot with standard soil conditions. Projects with challenging site conditions, extensive structural work, or premium finishes will vary.
A new room, fully finished — designed to feel like it was always there
Starting at
$90,000 – $200,000
Estimated Duration: 5–8 months
Pricing reflects mid-range room addition with standard site conditions and mid-range finishes. ADUs, primary suite additions, and projects with premium finishes or challenging site conditions will vary.
Major expansion — significant square footage added with full design-build coordination
Starting at
$200,000+
Estimated Duration: 8–14 months
Second story additions, large footprint expansions, and projects with complex structural or site requirements will vary significantly. Timeline includes permit processing which varies by jurisdiction.
Prices above reflect average ranges based on typical scope and site conditions in the greater Sacramento area. Addition costs are highly variable based on soil conditions, existing structural capacity, permit jurisdiction, and finish selections. An on-site consultation is the most accurate way to assess your specific project.

Every addition project starts with your goals, your lot, and your home's existing structure. We assess feasibility, manage design and engineering, handle all permits and inspections, and build the addition with the same finish quality we bring to our remodel work.
Single-room additions — a new bedroom, family room, or home office — designed and built to integrate seamlessly with your existing home. We handle the full scope from foundation and framing through roofline integration, exterior finish, and complete interior build-out.
Detached and attached ADUs — fully independent living units with their own kitchen, bathroom, and entrance. Sacramento’s ADU-friendly zoning makes this one of the smartest investments a homeowner can make, whether for rental income, multigenerational living, or a home office.
Adding a second story dramatically increases your home’s square footage without expanding the footprint. We manage the full structural engineering scope, temporary living arrangements during construction, and complete interior and exterior finish to ensure the addition looks original to the home.
Converting an underused garage into livable space — a bedroom suite, home office, gym, or ADU — is one of the most cost-effective ways to add square footage. We handle all structural modifications, insulation, HVAC, electrical, plumbing, and finish work.
Sunroom additions and patio enclosures that extend your living space while maintaining a connection to your outdoor environment. We build insulated, climate-controlled sunrooms that function as year-round living space — not seasonal screen rooms.
A bump-out extends an existing room by a few feet — enough to transform a cramped kitchen, add a breakfast nook, or expand a primary bathroom. Smaller in scope than a full addition, bump-outs deliver meaningful space gains with less disruption and lower cost.
Sacramento's real estate market makes moving expensive — between closing costs, moving expenses, and the price premium on larger homes, the total cost of upsizing often exceeds the cost of expanding where you are. A well-executed addition gives you the space you need while keeping you in the neighborhood, the school district, and the community you already know.
For homeowners in the greater Sacramento area's premium markets — Granite Bay, El Dorado Hills, Folsom — a quality addition also adds measurable value to the property. A well-integrated addition that matches the home's existing architecture and finish level is one of the highest-ROI improvements a homeowner can make.
Parrish Construction manages home addition projects as a full design-build general contractor. That means one team, one contract, and one point of accountability from the first consultation through the final walkthrough. We coordinate architects, structural engineers, subcontractors, and inspections — so you don't have to.
