—Know Your Rights as a California Homeowner
Before you sign a contract or hand over a deposit, here's what every California homeowner should know about hiring a licensed contractor — sourced from CSLB and other official state resources.
Verify a Contractor's License
Every contractor working on jobs over $500 in California must hold an active CSLB license. You can look up any license number to confirm it's current, check the bond status, see the license classification, and review any complaint or disciplinary history — all in one place. It takes less than a minute and can save you from a costly mistake.
Under California's Home Solicitation Sales Act, you have 3 business days to cancel any home improvement contract signed at your home or away from the contractor's place of business — no penalty, no questions asked. If you are 65 or older, that window extends to 5 business days. As of 2026 (AB 1327), contractors must also allow cancellation by email, making it easier to exercise this right in writing.
General Liability & Workers' Compensation Insurance
General liability insurance protects your property if a contractor accidentally causes damage during the job. Workers' compensation covers medical costs and lost wages if a worker is injured on your property — without it, you could be held financially responsible. Always ask for proof of both before work begins, and verify the policies are current.
Mechanics Liens & the Notice to Owner
If you receive a Preliminary Notice (sometimes called a Notice to Owner), don't panic — it's a standard legal document that subcontractors and material suppliers are required to send in California to preserve their right to file a mechanics lien if they aren't paid. It doesn't mean anything is wrong, but it does mean you should confirm your prime contractor is paying their subs and suppliers on time. Unpaid liens can attach to your property title.
Know Who's Working on Your Home
As of 2026 (SB 517), California homeowners have the right to request the name, license number, and contact information of any subcontractor your prime contractor plans to use on your project. Don't hesitate to ask — a reputable contractor will provide this information without hesitation, and you can verify each sub's license independently through CSLB.
Permits Matter
Permits aren't just red tape — they trigger inspections that protect you by confirming work meets California building codes. Unpermitted work can create problems when you sell your home, void your homeowner's insurance, or require costly tear-out and redo later. Always ask your contractor which permits are required for your project, and confirm the permit was actually pulled by checking with your local building department before work begins.
How to File a Complaint
If something goes wrong with a licensed contractor — abandoned work, shoddy craftsmanship, unlicensed activity, or failure to honor a warranty — you can file a formal complaint with CSLB at no cost. CSLB investigates complaints, can issue citations, suspend or revoke licenses, and in some cases help recover funds. Filing a complaint also protects future homeowners from the same contractor.
The California Building Code is based on the International Building Code with California-specific amendments. It governs structural requirements, fire safety, accessibility, and energy efficiency for all new construction and major renovations. Your contractor is legally required to build to CBC standards — not just local preferences. Understanding the basics helps you ask the right questions and spot red flags early.
California's Title 24 Energy Code sets minimum efficiency requirements for insulation, windows, HVAC systems, lighting, and water heating in residential and commercial buildings. Compliance is verified at permit inspection. Non-compliant work can require costly retrofits and may affect your home's resale value. Always confirm your contractor is designing to current Title 24 standards before construction begins.
California sits on active fault lines, and the CBC includes strict seismic design requirements for foundations, framing, and structural connections. Additions, remodels, and new construction in high-seismic zones must meet these standards. If your contractor skips or shortcuts seismic strapping, anchor bolts, or shear wall requirements, your home may not survive a significant earthquake — and your insurance claim could be denied.
Fire & Wildland-Urban Interface (WUI) Codes
If your property is in a State Responsibility Area or a High or Very High Fire Hazard Severity Zone, additional fire-resistant construction requirements apply under the California Fire Code and CBC Chapter 7A. These include ignition-resistant siding, ember-resistant vents, multi-pane windows, and Class A roofing. Your contractor must know your property's fire zone designation before designing or bidding the project.
Commercial projects and multi-family residential buildings must comply with the Americans with Disabilities Act (ADA) and California's more stringent accessibility standards under the CBC. Even single-family remodels can trigger accessibility upgrades when the scope of work exceeds certain thresholds. Your contractor should identify any accessibility triggers during the design phase — not after the permit is pulled.
Plumbing & Electrical Code Compliance
California adopts the California Plumbing Code and California Electrical Code with state-specific amendments. These codes govern everything from panel sizing and circuit protection to pipe materials and water heater installation. Work performed without permits or inspections may not meet code, creating safety hazards and liability issues that fall on the homeowner — not the contractor — after the job is done.
CALGreen — California Green Building Standards
CALGreen (Title 24, Part 11) sets mandatory green building standards for new construction and major renovations, covering water efficiency, construction waste reduction, indoor air quality, and EV charging infrastructure. A knowledgeable contractor will incorporate CALGreen compliance into the project plan from day one — not as an afterthought at final inspection.
Getting multiple bids isn't just about finding the lowest price — it's about understanding the market rate for your project and identifying outliers. A bid that's dramatically lower than the others often signals that the contractor plans to cut corners, use inferior materials, or add change orders once work begins. Three bids give you a baseline to evaluate scope, materials, and approach — not just price.
Require a Detailed Written Contract
California law requires a written contract for any home improvement job over $500. The contract must include the contractor's license number, a detailed description of the work, materials to be used, start and estimated completion dates, the total price and payment schedule, and the 3-day cancellation notice. Never pay in full upfront, and never sign a contract with blank spaces.
Ask every contractor for at least three references from projects similar in scope to yours, completed within the last two years. Call those references and ask specific questions: Was the project completed on time and on budget? Were there unexpected change orders? How did the contractor handle problems? Would you hire them again? Online reviews are useful, but direct reference calls give you information reviews rarely capture.
Understand the Payment Schedule
California law limits the initial deposit on home improvement contracts to 10% of the total price or $1,000 — whichever is less. Progress payments should be tied to completion of defined milestones, not arbitrary dates. Never pay ahead of the work. Final payment should be withheld until the job is complete, all inspections have passed, and you've confirmed that all subcontractors and suppliers have been paid.
Manage Change Orders in Writing
Change orders are written amendments to the original contract that document any changes in scope, materials, or price. Every change — no matter how small — should be documented in a signed change order before the work proceeds. Verbal agreements about changes are nearly impossible to enforce and are a leading cause of contractor disputes. A professional contractor will initiate change orders proactively.
Request Lien Releases at Each Payment
Each time you make a progress payment, request a conditional lien release from your general contractor and, where applicable, from major subcontractors and material suppliers. A conditional release becomes unconditional once your check clears. Collecting lien releases at each payment milestone creates a paper trail that protects your property title from mechanics liens filed by unpaid subs or suppliers.
Do a Thorough Final Walkthrough
Before making your final payment, conduct a detailed walkthrough with your contractor and document every item that needs correction on a written punch list. Confirm that all permits have received final sign-off from the building department, that all debris has been removed, and that you've received all warranties, manuals, and as-built documentation for the work performed.
San Diego County Planning & Development Services
The San Diego County Department of Planning & Development Services (PDS) handles permits, zoning, and land use for unincorporated areas of San Diego County. If your property is in an unincorporated area — such as parts of Lakeside, Ramona, Alpine, or Spring Valley — your permits are pulled through PDS, not a city building department.
Properties within the City of San Diego limits use the City's Development Services Department for permits and inspections. The City offers online permit applications, inspection scheduling, and permit status tracking through its Development Services portal. For projects in the City of San Diego, your contractor must pull permits through this department — not the County.
San Diego County has one of the highest concentrations of Very High Fire Hazard Severity Zones in California. Many residential neighborhoods in East County, North County, and hillside communities fall within WUI zones that require fire-resistant construction materials and ember-resistant vents. Before starting any exterior work, your contractor should confirm your property's fire zone designation and design accordingly.
Properties within the California Coastal Zone — which includes significant portions of San Diego County — require a Coastal Development Permit (CDP) in addition to standard building permits for most construction, additions, and significant remodels. Coastal permitting adds time and complexity; your contractor should factor this into the project schedule from the start.
Every property in San Diego County has an Assessor's Parcel Number (APN) that links to its zoning designation, land use restrictions, and permit history. Knowing your APN and zoning before you start planning a project can save significant time and money — some zones prohibit certain additions or ADUs. Use our free Parcel Lookup tool on the Services page to check your property instantly.
California has significantly streamlined ADU (Accessory Dwelling Unit) permitting in recent years. Most single-family lots can now add at least one ADU and one Junior ADU (JADU). Setback requirements, height limits, and owner-occupancy rules vary by jurisdiction. An ADU can add significant value to your property — and Golden Group specializes in ADU construction throughout San Diego County.
Hiring a Licensed Contractor in San Diego
San Diego County sees a high volume of unlicensed operator complaints — particularly after major storms or wildfires when demand spikes. Always verify a contractor's CSLB license before signing anything, confirm they carry current general liability and workers' compensation insurance, and check that their license classification matches the work you're hiring them for. Golden Group Construction holds CSLB License #1091901.
