Planning repairs & maintenance in California
One statewide code, with local amendments
California builds to Title 24, the California Building Standards Code. The 2025 edition took effect on January 1, 2026, and has separate parts for residential construction, energy, green building, existing buildings and the wildland-urban interface. A city or county can change these standards only after making an express finding that the change is reasonably necessary because of local climatic, geological or topographical conditions, and filing that finding with the Building Standards Commission. From October 1, 2025 through June 1, 2031, state law also has the Commission reject most new local changes to standards for residential units, with narrow exceptions such as emergency standards and home hardening. Local amendments already in place can still differ from one city to the next.
Sixteen energy code climate zones
The California Energy Code (Title 24, Part 6) divides the state into 16 building climate zones. Several efficiency standards, including those for the building envelope and for windows and doors, depend on the zone a building sits in, and the California Energy Commission offers an online search tool for finding a building's zone. The energy standards are updated every three years, and the 2025 standards took effect on January 1, 2026.
Wildfire hazard zones
CAL FIRE maps Fire Hazard Severity Zones rated moderate, high or very high, based on factors such as fuel, slope and fire weather. The zones mark where the state's defensible space standards and wildland-urban interface building codes are required, and they can be a factor in real estate disclosure. CAL FIRE's guidance notes that wind-blown embers can ignite roofs, attics through vents, and decks, and that local ordinances may require ignition-resistant construction for remodels, so the local building department confirms which rules apply.

Permits
Small like-for-like repairs, such as replacing trim, patching drywall or rehanging a door, often do not need a permit. Work that changes structure, rebuilds a significant part of a deck or stair, or alters electrical, plumbing, gas or mechanical systems commonly does. Requirements vary by city and county, and the local building department confirms what applies. Any required permit should be in place before that work starts.
Contractor licensing
Contractors State License Board (CSLB)
California licenses contractors statewide through the Contractors State License Board (CSLB). Under Business and Professions Code Section 7048, as raised by AB 2622 on January 1, 2025, a license in the appropriate classification is required when a job's total price for labor, materials and all other items is $1,000 or more, when the work needs a building permit, or when the person doing it employs others. Home Improvement Salespersons hold a separate CSLB registration. Before you sign, look up the license or registration on CSLB's online lookup, which also shows complaint disclosures. On a home improvement contract, state law caps any down payment at $1,000 or 10 percent of the contract amount, whichever is less.

Permits in California
State law directs the building department of each city or county to enforce the State Building Standards Code for housing within its jurisdiction, so the department that handles your project depends on whether the address is inside a city or in an unincorporated part of a county. Every department works from the same Title 24 code but may have local amendments, its own list of work that needs plans, and faster permit paths for simple jobs, such as express permits in Los Angeles and no-plan permits in San Diego. Where a homeowners association reviews changes, that approval is a separate step, and state law says the association's decision cannot violate a building code. Permit needs are confirmed for your address during planning, before work is scheduled.

- Items that are not on the agreed list. New findings are written up and approved by you before any added work.
Budget planning
What affects cost
Number and spread of items
Several repairs in one area take less setup and cleanup than the same number spread across the house and exterior.
Access
Second-story trim, crawlspaces and tight attics need ladders, staging or extra protection, which adds time.
Hidden damage
Rot, water staining and insect damage often run past what is visible. Once a board or panel is opened, the scope can change, and we confirm with you before going further.
Matching existing materials
Older trim profiles, discontinued siding and custom hardware can take longer to source, or may need to be milled or adapted to fit.
Replacement material
Replacing a rotted board with primed wood, PVC or composite trim changes both the material cost and how long the repair holds up.
Finish level
Leaving repairs primed costs less than full painting and color matching, which can also need return trips for drying time.
Age of the building
In homes built before 1978, work that disturbs painted surfaces calls for lead-safe work practices, which add setup, containment and cleanup.
Scheduling
What affects the schedule
- How many items are on the list and whether they need different materials
- Special-order parts, custom trim profiles or hard-to-match materials
- Weather for exterior repairs, since sealants and paint need dry conditions and suitable temperatures to cure
- Drying time for patching compound, wood filler, primer and paint between coats
- Occupied rooms, tenants or business hours that limit when work can happen
- Whether a repair uncovers damage that needs its own scope
How to prepare
- Write down every item, even small ones, with its room or location. Photos help.
- Share any home inspection report, product manuals or paint colors you have on file.
- Clear a path to each repair and move fragile items and furniture away from the work area.
- Know where your main water shutoff and electrical panel are in case a fixture swap needs them turned off.
- Keep pets and children away from work areas while tools are in use.
- Tell us if the building was built before 1978, since that changes how painted surfaces are handled.
Process
How Repairs & Maintenance Projects Work
- 1
Consult
You send your list, photos or inspection report. We walk the items with you, flag anything that points to a larger problem, and separate urgent repairs from ones that can wait.
- 2
Plan
We group items by area and material, confirm what gets replaced and what gets patched, order parts, and give you a written scope that lists each item.
- 3
Build
Repairs are completed in the agreed order with floors and furniture protected. If opening a wall or board shows more damage, we stop, show you, and agree on the change before continuing.
- 4
Enjoy
We go through the list with you item by item, leave the work areas clean, and note anything worth watching at the next seasonal check.

Questions
Repairs & Maintenance FAQs
What counts as a repair instead of a remodel?
A repair restores something to working order with similar materials, such as replacing a rotted sill or rehanging a door. A remodel changes the layout, function or finishes of a room. If your list starts to change how a space works, we will say so and scope it as a remodel instead.
Can you handle a long list of small repairs at once?
Yes. A full list is the most efficient way to use a repair visit. Send every item with photos. We group items by area and material, and a longer list may be split into more than one visit so parts and drying time line up.
Do repair visits include plumbing and electrical work?
Simple like-for-like swaps may fit into a repair visit where local rules allow. Anything that changes wiring, circuits, supply lines, drains or gas lines is handled by appropriately licensed trades and often needs a permit.
What happens if you find more damage than expected?
We stop, show you what we found with photos, explain the options, and write up the added work. Nothing outside the agreed list is done without your approval.
Is there anything different about repairs in an older home?
Yes. Homes built before 1978 may contain lead-based paint, and EPA requires anyone paid to disturb painted surfaces in those homes to be certified and to use lead-safe work practices. EPA also notes that older textured paints and patching compounds on walls and ceilings may contain asbestos.
Is seasonal maintenance worth scheduling?
Small problems like failed caulk, a clogged downspout or a split trim board let water in. Water damage is usually more involved to repair than the gap that caused it. A spring and fall check catches these problems while they are still small.
