Aging-in-Place Remodeling in California: Homes, Licenses, Who Pays

California had 6,901,168 residents 65 and over on July 1, 2025, 17.5% of the state, according to the Census Bureau's Vintage 2025 estimates released in June 2026. The homes are older single-story tracts and two-story suburbs (the typical US home is 41 years old), built under seismic, water-saving and, in hillside areas, wildfire rules that reach into almost any bathroom or entry job. Anyone doing $1,000 or more of work must hold a Contractors State License Board (CSLB) license. Most California families pay directly, with Medi-Cal, Medicare Advantage, long-term care insurance, VA grants and a few county and city programs covering specific cases.

California by the numbers

• 6,901,168 Californians were 65 or older on July 1, 2025, 17.5% of 39,355,309 people (Census Bureau Vintage 2025 county estimates, released June 2026).
• That is 877,885 more than in 2020, up 14.6%, slightly behind the national growth of 16.2% (Census Bureau, Vintage 2025).
• The highest shares are in smaller counties: Nevada County 30.4%, El Dorado 26.2%, Marin 25.7%, Sonoma 24.2% (Census Bureau, 2025).
• The Contractors State License Board licenses about 285,000 contractors (CSLB).

Why California homes are different

Single-story tracts, two-story suburbs, hillside lots. Older neighborhoods are largely single-story stucco houses, many on raised foundations with steps up to the front door; newer suburbs are mostly two-story; and many homes sit on sloped lots with long exterior stairs. In a single-story house the work is the entry, the bathroom and the floors, and the entry fix is railings and a ramp or step-free entry. In a two-story house it is a stair lift or moving the bedroom and bath downstairs. In a Very High Fire Hazard Severity Zone, replacement windows need dual panes with a tempered pane or a 20-minute rating (California Wildland-Urban Interface Code).

Earthquake and water rules. Every new or replacement water heater must be strapped or braced (Health and Safety Code 19211). CALGreen caps showerheads at 1.8 gallons per minute, faucets at 1.2 and toilets at 1.28 gallons per flush, and an alteration can require replacing noncompliant fixtures elsewhere in the house (Civil Code 1101.4). A bathroom safety remodel also needs a shower valve limited to 120°F, safety glazing and GFCI outlets, and the cheap quote leaves those out.

What needs a permit. Replacing or relocating a toilet, sink, tub or shower, altering electrical, or replacing drywall needs a permit. Towel bars, mirrors and paint do not. A grab bar is handyman work; a curbless shower is a permit job every time.

Checking a California contractor's license

The usual classes for an aging-in-place remodel are B General Building, or B-2 Residential Remodeling, which covers existing wood-frame homes but cannot alter load-bearing walls or substantially change plumbing, electrical or heating systems. Plumbing (C-36) and electrical (C-10) are separate licenses, as are tile, glazing and flooring.

A license is required for any job of $1,000 or more in labor plus materials, a threshold that rose from $500 on January 1, 2025 under AB 2622, and for any smaller job that needs a permit or uses hired helpers.

Check the license at the CSLB's Check a License page or at (800) 321-2752. The status must be Active. The detail page shows the required $25,000 bond, workers' compensation status and any discipline. California also caps the down payment on a home improvement contract at $1,000 or 10% of the price, whichever is less. The Certified Aging-in-Place Specialist (CAPS) designation is a good sign on top of the license, not a substitute. Our guide on how to choose an aging-in-place remodeler has the full checklist.

Who pays in California

Most California families pay directly, from savings, a home equity line, or siblings splitting the cost. It is the fastest path: no pre-approval and your choice of contractor. Paying out of pocket covers the tools, including the reverse mortgage (HECM) for homeowners 62 and over.

The other channels:

• Medicare and Medicare Advantage. Original Medicare pays nothing toward home modifications. Some Medicare Advantage plans add a bathroom safety allowance (a commonly cited figure is up to $500 a year); structural work is rarely covered. See Medicare and Medicare Advantage.
• Long-term care insurance. Many policies include a home modification benefit tied to help with activities of daily living, after pre-approval. See long-term care insurance.
• Medi-Cal. California's Medicaid program is run by the Department of Health Care Services. Ask it what home modification coverage exists and whether there is a waitlist. See Medicaid waivers.
• Veterans. The VA's HISA grant pays for medically necessary alterations prescribed by a VA clinician. See VA grants.
• Property tax. Accessibility work for a disabled resident is excluded from reassessment under Revenue and Taxation Code sections 74.3 and 74.6. File form BOE-63 or BOE-63-A with the county assessor before the work or within 30 days of finishing it. Federal tax deductions may apply.
• County and city programs. There is no statewide grant for senior home modifications. Los Angeles County, the City of Los Angeles and San Diego County each run an income-limited repair program, Rebuilding Together affiliates in Sacramento, Silicon Valley, San Francisco, San Diego and Los Angeles install free grab bars, railings and ramps for low-income older homeowners, and many cities run CDBG-funded accessibility grants. Most have waitlists. Details are on the city pages and on senior bathroom remodel programs.
