Home Additions in Sherman Oaks, CA

More Space, Same Address

Superior Home Builders helps Sherman Oaks homeowners add square footage without leaving the neighborhood. We design and build second-story additions, rear and side expansions, and new primary suites, and we handle permits and construction as one project.

A Neighborhood People Stay In

Sherman Oaks was founded in 1927, when Moses Sherman’s Los Angeles Suburban Homes Company subdivided roughly a thousand acres. The community runs along Ventura Boulevard from the Sherman Oaks Galleria area to the Santa Monica Mountains, and includes pockets like Magnolia Woods and Chandler Estates.

Homeowners here tend to value location: access to Ventura Boulevard, the 101 and 405 freeways, and the hills. When a household outgrows its home, moving means leaving all of that. An addition keeps the address and adds the space. Our guide to room addition versus moving walks through how to compare the two.

Love the Neighborhood but Need More Space?

Home Additions

A home addition adds a larger piece of the house: a primary suite, an expanded kitchen and family room, or a second story. Second-story additions leave the yard intact, but they involve structural review of the existing foundation and framing. Our guide to adding a second story in LA explains the process, permits, and structural considerations.

See one of our projects, a custom home addition, for an example of how an addition can blend with the original architecture.

Room Additions

When one specific space is the problem, a targeted room addition can be a better fit than a full expansion. A bedroom, a home office or a larger family room can often be added without rebuilding the house.

Full Home Remodeling

An addition rarely stands alone. The new space has to connect to the existing floor plan, and the old rooms often need updating to match. Our full home remodeling service coordinates both.

ADU Construction

If you want a separate space rather than more house, an ADU can serve guests, family, or a home office.

Which Project Fits Your Home?

Project Type	Good Fit When	What It Can Change
Second-Story Addition	The lot is full, but the home is small	Adds bedrooms or a suite upward
Rear or Side Addition	You have usable yard space	Family room, kitchen, primary suite
Room Addition	One space is the problem	Bedroom, office, family room
ADU	You want separate living space	Guest, family, work or rental use

Building Additions in Sherman Oaks: What to Know

Sherman Oaks is part of the City of Los Angeles, so building permits go through LADBS and zoning through LA City Planning. An addition changes the home’s footprint or height, so it typically needs structural engineering, plan check, and inspections. Floor area, height and setbacks vary by zone and lot.

Hillside areas change the picture. Sherman Oaks includes part of the Santa Monica Mountains, and parts of the hillsides may be subject to hillside floor-area and grading rules, fire-zone construction requirements, and the Mulholland Scenic Parkway Specific Plan for properties near Mulholland Drive. Which rules apply depends on the parcel, so we check it in ZIMAS before design begins.

What Affects the Cost of an Addition?

Cost depends on size, whether the addition is one story or two, foundation and structural work, roofline complexity, plumbing and electrical extensions, finishes, engineering, and permits. Matching existing materials and tying new framing into an older house also takes planning. We explain these factors during consultation and price against a completed design rather than publishing a generic range.

From First Sketch to Final Walkthrough

Initial consultation: We review your goals, budget, site conditions, and zoning constraints.
Design and planning: Plans, blueprints, and 3D renderings with our design team or your architect, then permits.
Material selection: Finishes and materials that match the existing home.
Construction: Foundation, framing, utilities, and interior work, with on-site progress monitoring.
Quality control: Inspections and testing at key milestones.
Final walkthrough: A comprehensive review and final sign-off.

Building Additions Across Sherman Oaks

Flatland streets near Ventura Boulevard and Van Nuys Boulevard raise different questions than the higher hillside streets. Magnolia Woods, a 45-block area between Burbank and Magnolia Boulevards, and Chandler Estates each have their own street character. We plan additions around what the neighborhood looks like and what the lot allows.

Frequently Asked Questions

Does Superior Home Builders build additions in Sherman Oaks?

Yes. We are a licensed California general contractor (license #875933) building home and room additions, second stories, remodels, and ADUs across the Valley, including Sherman Oaks.

Who issues addition permits in Sherman Oaks?

Sherman Oaks is part of the City of Los Angeles, so LADBS issues building permits and LA City Planning handles zoning. We prepare the drawings, submit the application, and manage plan check and inspections.

Can an older Sherman Oaks home support a second story?

Sometimes. A structural engineer evaluates the existing foundation and framing, and reinforcement may be needed. Zoning height limits and, on hillsides, additional regulations also apply. We review all of it before recommending a design.

Do I need a permit for a room addition?

Yes. Adding square footage requires permits, plans and inspections. Your lot, zoning and any hillside designation determine how large the addition can be.

Can I stay in my home during construction?

Often, yes, especially for rear or side additions. Second-story additions are more disruptive and may require temporary relocation during the structural phase. We discuss this before work begins.
