Remodeling in San Diego: what to know

Census figures put the median San Diego home at 1978, with 54% of the housing stock built before 1980.

The older the house, the more likely the walls, floors and foundation hold surprises, which is why our quotes list a clear allowance for them.

We remodel homes across San Diego, including Carmel Valley, Rancho Bernardo, Mira Mesa, Kensington, Mission Hills and Point Loma.

Local tips

  • Coastal neighborhoods deal with salt air, so stainless and powder-coated hardware outlasts plain metal finishes.
  • Many San Diego homes were built before 1980, so older wiring and galvanized plumbing often turn up once walls open.
  • Some coastal areas fall in the Coastal Zone, where exterior changes can need extra review.

Do you need a permit in San Diego?

New living space, conversions of garages, basements or attics, and any structural, electrical or plumbing changes typically need permits and inspections; cosmetic updates usually need none. Additions and ADUs must also meet local zoning rules such as setbacks. The City of San Diego Development Services Department issues building permits for addresses inside city limits.

In California, any job of $1,000 or more in labor and materials, or any job that needs a permit, must be done by a CSLB-licensed contractor. The limit was $500 until AB 2622 raised it in 2025.

A CSLB license lookup takes a minute and shows whether the license is active and bonded. Contractors State License Board (CSLB)

Does a remodeling contractor need a license in California?

In California, any job of $1,000 or more in labor and materials, or any job that needs a permit, must be done by a CSLB-licensed contractor. The limit was $500 until AB 2622 raised it in 2025. A CSLB license lookup takes a minute and shows whether the license is active and bonded.

Is it cheaper to finish a basement or build an addition?

Finishing space already under roof is almost always cheaper, often a third or less of the cost per square foot of an addition, because the foundation, walls and roof already exist.

What does it cost to finish a basement?

Basement finishing typically runs about $35–$85 per sq ft nationally, before local price differences. Adding a bathroom usually adds $16,700–$38,900, and an egress window for a bedroom $2,800–$7,200.

Can I turn my garage into a room?

Usually, yes. The work covers insulation, closing in the door opening, windows, power, heating and a floor raised or leveled to living-space standards. Some cities require you to replace the lost parking elsewhere, so we check that first.

What does an ADU cost?

Most cities allow some form of ADU now, but the rules vary a lot. We check your lot first. Converting existing space is the lowest-cost route; a new detached unit is the most expensive.

Will we need to move out?

Usually. Additions and conversions are mostly built apart from the living space until they are joined. Expect some noise and a few short shutoffs of water or power.

What adds cost once work starts?

Older houses often hide knob-and-tube or ungrounded wiring, old plumbing and little insulation. Homes built before 1978 may also have lead paint, and some older materials contain asbestos, which should be tested before demolition. Utility connections, drainage and changes made mid-project are the other usual budget changes.

Which remodels pay back at resale?

Added living space generally raises a home value, but rarely by the full cost. If you are selling soon, keep the scope modest; if you are staying, plan for how you live.
