Room Addition

Room Addition

Add a bedroom, living room, sunroom, or flex space to your Folsom home with a permitted room addition built to match your existing architecture.

Second Story

Second Story Addition

Transform your single-story Folsom home into a two-story property — dramatically increasing square footage and property value.

ADU

ADU & Guest House

California ADU law makes it easier than ever to add a separate dwelling unit to your Folsom property — for rental income or family housing.

Garage Conversion

Garage Conversion

Convert your attached or detached Folsom garage into living space — a home office, bedroom, gym, or studio.

Bonus Room

Bonus Room Addition

Add an entertainment room, home theater, playroom, or flex space above your garage or as a ground-floor addition.

Why Add On Instead of Moving

The financial case for adding on to your Folsom home.

With Folsom home prices near $700,000 and the transaction costs of buying and selling running 8 to 10 percent, a well-designed home addition almost always makes more financial sense than moving.

Cost of Moving
8–10% in costs

Agent commissions, closing and transfer costs, moving expenses, and the price premium for a larger Folsom home all add up fast — often well over $100,000 before you’ve gained any extra space.

Cost of Adding On
$100K–$350K

A typical Folsom addition costs less than trading up and every dollar goes directly into your own home — not into transaction fees. Room additions and garage conversions sit at the lower end; ADUs and second stories higher.

Return on Investment
Stay & gain

A permitted Folsom addition increases square footage and property value, can create rental income with an ADU, and eliminates the need to move — keeping you in the home and neighborhood you already love.

Folsom Addition Projects

Home additions built in Folsom and surrounding communities.

Second Story Addition
Empire Ranch Second Story
Before

A cramped single-story home where a growing family had outgrown three small bedrooms and a single shared bath on one level.

After

A full second-story addition added a primary suite and two bedrooms, nearly doubling the square footage while matching the original rooflines and exterior.

Detached ADU
Broadstone Garden ADU
Before

An underused side yard and aging detached garage that added nothing to the property beyond storage.

After

A permitted detached ADU with a full kitchen, bath, and living space — now a private suite for aging parents and future rental potential.

Garage Conversion
Willow Creek Garage Conversion
Before

A two-car garage used as a catch-all, while the family lacked any dedicated work-from-home space.

After

A fully finished, insulated, and permitted home office and gym with its own entry, heating, and natural light — gained without changing the footprint.

Folsom Home Addition FAQ

The questions Folsom homeowners ask about home additions.

How much does a home addition cost in Folsom, CA?

+

Folsom home addition costs vary by type and size. A room addition typically runs from the low six figures, a garage conversion is often less, and a second-story addition or detached ADU usually carries the highest investment because of structural and systems work. As a rough guide, most Folsom additions fall between $100,000 and $350,000. After we assess your lot and home, we provide a detailed, fixed written estimate for your specific project.

How long does it take to build a home addition in Folsom?

+

Most Folsom home additions take three to six months from groundbreaking to final inspection, preceded by design and City of Folsom permitting. Room additions and garage conversions are on the shorter end, while second-story additions and ADUs take longer due to structural work. We provide a phase-by-phase schedule before construction and keep you updated throughout.

What permits does the City of Folsom require for home additions?

+

Home additions in Folsom require building permits through the City of Folsom, typically including structural, electrical, mechanical, and plumbing permits plus Title 24 energy compliance and engineered plans. Additions that change the footprint or add a second story trigger full structural review. As your licensed General B Contractor, we prepare the plans, pull every permit, and manage all inspections from start to finish.

Can I build an ADU on my Folsom property?

+

Very likely. California’s ADU laws are favorable, and many Folsom lots have room for an attached or detached accessory dwelling unit or a garage-conversion ADU. We assess your lot size, setbacks, utilities, and any HOA limitations, then design and build an ADU that complements your home — ideal for rental income, a home office, or multigenerational living. We manage the entire City of Folsom permit process.

Will a home addition in Folsom increase my property value?

+

Yes. A well-designed, permitted home addition adds usable square footage, which is one of the most direct ways to increase a Folsom property’s value — and ADUs additionally create income potential that buyers prize. Just as important, an addition lets you stay in the Folsom home and neighborhood you love rather than absorbing the cost of selling and buying up.
