Home Addition Contractor in Encino, CA
Looking for a home addition contractor in Encino? HomeSense Construction & Remodeling designs, permits, and builds room additions, primary-suite additions, and second-story additions across Encino and the San Fernando Valley — from Amestoy Estates and Encino Village to the hillside streets south of Ventura Boulevard. Licensed and insured (CA Lic #1125001), building since 2011.
Why Encino Homeowners Add On Instead of Moving
Encino home values are among the strongest in the Valley, and trading up means losing a low Proposition 13 tax basis, paying transfer costs, and competing for limited inventory. A well-designed addition lets you stay in the neighborhood you chose — near Los Encinos State Historic Park, the Sepulveda Basin, and Ventura Boulevard’s shops and restaurants — while adding the space a growing or multi-generational household needs. Most Encino lots north of the Boulevard are generous postwar R-1 parcels with room to expand outward; south-of-the-Boulevard hillside properties often favor a second story or a stepped addition engineered to the slope.
Types of Additions We Build in Encino
- Room & family-room additions — extend the main level for a larger living area, home office, or playroom.
- Primary-suite additions — bedroom, walk-in closet, and spa bath; the highest-demand addition in Encino’s older ranch homes.
- Second-story additions — double your footprint without losing yard space; ideal where lot coverage or setbacks limit ground-floor expansion.
- In-law & multi-generational suites — attached suites with private entries; if you’re weighing a separate unit instead, see our guide comparing a room addition vs. an ADU or our ADU builder in Encino page.
- Kitchen bump-outs & dining extensions — modest square footage, major daily-life impact.
Our Process
One licensed team handles everything: feasibility and budget consultation, architectural design and structural engineering, Los Angeles Department of Building and Safety (LADBS) permitting through the Van Nuys office, construction, and final inspections. You get a dedicated project manager, a written schedule, and transparent line-item pricing.
What’s Included
Foundation and framing, roofing tied seamlessly into the existing structure, electrical, plumbing and HVAC extensions, insulation and drywall, windows and doors, and interior finishes matched to your home. Encino homes built before 1960 often need foundation bolting or shear-wall upgrades when adding load — we evaluate that up front, not as a mid-project surprise.

Frequently Asked Questions
How much does a home addition cost in Encino?
Most Encino room additions run $280–$400 per square foot in 2026; second-story additions run $400–$700 per square foot. A typical 500–900 sq ft project totals roughly $170K–$380K depending on scope and finishes.
Do I need a permit for a home addition in Encino?
Yes. Encino is within the City of Los Angeles, so additions are permitted through LADBS (Van Nuys office). We handle plans, engineering, permit submission, and all inspections.
How long does a home addition take?
Plan on 2–4 months for design and permitting and 3–6 months for construction, depending on size and structural complexity. Second-story additions take longer than ground-level rooms.
Is an addition or an ADU better for my Encino property?
An addition expands your main living space; an ADU creates a separate rentable unit. If you want rental income or full independence for family, an ADU often wins; for connected everyday space, an addition does. We build both and can compare options at your property — see our room addition vs. ADU guide.
