What do National City homes need?
Central San Diego neighborhoods have dense housing with attached and detached garages that make strong ADU and bedroom conversion candidates, often for multigenerational households keeping parents or adult children on the same lot. Older electrical panels are common in older homes here, and a panel or subpanel upgrade is a frequent prerequisite before a full ADU conversion can proceed. Lot size and alley access vary block to block, so setbacks and separate-entry placement belong on a measured site plan, not assumed from the parcel map.
Census ACS data puts 66.2% of National City housing before 1978, so a conversion here often means bringing older framing and wiring up to current code.
How much does garage conversion cost in National City?
Most garage conversion projects in this area fall into a few tiers. A basic living space or bedroom conversion with insulation, drywall, flooring, and electrical runs $40,000-$70,000. A junior ADU sharing plumbing with the main home runs $50,000-$90,000. A full ADU conversion with a kitchen, separate bathroom, dedicated electrical meter, and all permits runs $75,000-$150,000 or more depending on the garage size, finish level, and required structural work. Garage door removal and wall infill, new windows, and exterior finish are included in most permitted conversion scopes.

What do National City homeowners ask?
How do I find an ADU builder or ADU contractor in National City?
Tell us about the garage and we match you with insured crews that already work in National City. Garage Convert SD is a referral service, not the contractor. You contract and pay the licensed crew directly, and they put the scope and price in writing after seeing the space.
Is a garage conversion the same as an ADU, a granny flat, or a casita?
Mostly yes. California code calls a self-contained unit an accessory dwelling unit, or ADU, and a smaller one built inside the house or an attached garage a junior ADU, or JADU. Granny flat, casita, in-law unit, and backyard cottage are the everyday names for the same thing. What changes the permit path is whether the garage is attached or detached and whether the unit gets its own kitchen and bath, not what you call it.

What does an ADU garage conversion involve in National City?
An ADU garage conversion turns the garage into an independent unit with its own kitchen, bath, and entry, so it needs a permit, plan check, and energy compliance documentation. A junior ADU is capped at 500 square feet, stays within the existing home footprint, and can share plumbing and entry with the main house. The National City crews we match handle the drawings and the permit when the scope calls for it.
