Flat South, Hillside North
Homes are largely 1950s and 1960s, built with 100 amp service and minimal insulation, so a second unit or a modern kitchen usually starts with a panel upgrade. On the northern hillside streets, expect grading review, a geotechnical report and engineered foundations as part of normal scope.
- /Deep postwar lots south of Rinaldi that support a detached ADU
- /Hillside grading review and engineered foundations to the north
- /100 amp panels needing upgrade before a second unit
- /Unbolted 1950s and 1960s framing on original foundations
- /Heat load that makes attic insulation and duct sealing worthwhile
What We Build in Granada Hills
Most of our Granada Hills projects fall into a handful of categories. Whichever one you're planning, you get a fixed-price proposal with real specifications instead of a vague per-square-foot guess.
- Kitchen remodels, from same-footprint refreshes to full layout changes
- Bathroom remodels with waterproofing done by our own crews
- Detached ADUs, attached ADUs and garage conversions
- Room additions and second-story additions
- Structural work: foundations, framing, seismic retrofits and wall removals
- Complete home remodels and ground-up custom homes
Working With 1960s ranches and north-slope hillside lots
Granada Hills is largely made up of 1960s ranches and north-slope hillside lots. Older houses here often need attention behind the walls before anything cosmetic makes sense, which is why we open things up early and price the real conditions instead of writing change orders later.
- Original wiring and undersized electrical panels
- Galvanized or cast-iron plumbing that needs replacing
- Framing that was never bolted to the foundation
- Little or no insulation and single-pane windows

Services We Offer in Granada Hills
FREQUENTLY ASKED QUESTIONS
Do you work in Granada Hills?
Yes. Granada Hills is part of our regular service area across the San Fernando Valley and Los Angeles County. We'll come out for a free on-site consultation, walk the property, and tell you what's realistic before you spend anything on design.
Do I need a permit to remodel in Granada Hills?
If you're moving plumbing, adding or relocating electrical, removing walls, or adding square footage, yes. Permits are issued through LADBS. Cosmetic work on the same footprint generally does not require a permit. We pull the permits for you and you reimburse the fees.
Can I build an ADU in Granada Hills?
In most cases, yes. California ADU law overrides many local restrictions, but setbacks, height limits, fire-severity zones, sewer capacity and your electrical panel still decide what's buildable. We review your specific parcel before any design work starts.
How much does a remodel cost in Granada Hills?
Bathrooms start at $18,000 for a guest bath, $28,000 for mid-range and $58,000 and up for a master suite, kitchens start at $35,000 for small, $55,000 for average and $80,000 and up for large, and ADUs $120,000 to $350,000. Whole-home remodels are usually quoted per square foot. Site conditions in Granada Hills and your material selections move the number, which is why we price after walking the property.
Are you licensed and insured to work in Granada Hills?
Yes. 1 Smart Build is a licensed, bonded and insured California general contractor. License details and proof of insurance are available on request, and every project is permitted and inspected.
