Quick answer
Planning a bathroom remodel in Los Angeles? Verify the contractor's California license, put the scope and payment schedule in writing, and determine whether the property is within a city or an unincorporated part of Los Angeles County.
Heads up: Check the address jurisdiction first. LA County Planning serves unincorporated areas outside a city. Properties within the City of Los Angeles or another incorporated city are served by the relevant city agencies. Ask the local building department which requirements apply to your address and proposed work.
How to Screen a Bathroom Remodeling Contractor
Start with the contractor's license information and written proposal. The Contractors State License Board licenses and regulates California's construction industry and provides both a contractor search and a license-check resource.
- Ask the contractor for the name and license number used for the proposed work.
- Use CSLB's Find A Licensed Contractor and License Check resources to review the official record.
- Make sure the information in the proposal and contract matches the contractor information you reviewed.
- Request a written scope identifying the work, fixtures and finishes included in the proposal.
- Review the payment schedule, exclusions and process for documenting changes before signing.
- Ask the building department serving the property what approvals or inspections are required for the proposed scope.
Heads up: A CSLB license check is a screening step. It does not guarantee workmanship or a particular project result.
Mr. Nailed It connects homeowners with independent contractors. It does not perform remodeling work, act as the contractor, manage crews or supervise construction. Homeowners remain responsible for reviewing contractor records, proposals and contract terms.
Compare Written Scopes, Not Just Totals
Ask each candidate to prepare a proposal for the same requested work. A written scope makes differences between proposals easier to identify before you choose a contractor.
- Which areas and tasks are included?
- Which fixtures, surfaces, hardware and finishes are specified?
- Are any requested layout changes included?
- Which items or services are excluded?
- What assumptions does the proposal make?
- How will changes and material substitutions be approved and documented?

Review the Contract and Payment Schedule
CSLB states that a home-improvement down payment should not be more than $1,000 or 10% of the contract price, whichever is less. Other payments must be clearly listed in the contract and based on the actual value of work already completed or materials delivered to the home.
- The amount or basis of each payment
- The completed work or delivered materials associated with each payment
- The fixtures, finishes, labor and other tasks included in the contract
- The exclusions and assumptions stated in the proposal
- The written procedure for approving changes

Identify the Agency Serving the Property
Los Angeles County includes incorporated cities and unincorporated areas. LA County Planning performs land-use planning functions for unincorporated Los Angeles County and serves as the planning department for areas outside a city.
Use the LA County Planning Jurisdiction Lookup to determine whether the property is in an unincorporated area and whether County Planning is its planning department. If the address is within a city, contact that city's building department instead of assuming LA County Planning has authority.
Describe the proposed bathroom work to the department serving the address and ask what permits, reviews or inspections are required. Do this before construction begins.
Check Current California Energy Standards
The 2022 Building Energy Efficiency Standards took effect January 1, 2023. The 2025 standards took effect January 1, 2026, according to the California Energy Commission.
Ask the building department serving the property which current standards and permit rules apply to the proposed work. The supplied state source does not establish the permit path for a particular Los Angeles address.
Consider WaterSense-Labeled Fixtures
The EPA encourages consumers to choose WaterSense-labeled products. EPA WaterSense includes showerheads and toilets among its product categories.
If you want WaterSense-labeled products, ask each contractor to identify the exact showerhead or toilet included in the proposal.
