Owner-Builder vs Licensed General Contractor in California: What the Law Allows and What You Sign in SLO County

Planning guide · updated October 2026

California lets property owners build or improve their own property without a contractor license, and plenty of people do it well, from a barn or shop on rural land to a full custom home. It is a real job, though, with legal duties that come with your signature on the permit. This guide explains what the owner-builder exemption covers, what the County of San Luis Obispo asks you to sign, the employer and insurance questions that come up, and how it compares with hiring a licensed general contractor, so you can choose with clear eyes. Questions? Call 805-712-8993.

The short answer

In California, Business and Professions Code section 7044 lets an owner build on their own property without a license if they do the work themselves or with wage employees, or if they contract directly with licensed trade contractors, as long as the structure is not built for sale. The owner-builder becomes the responsible party on the permit: hiring and scheduling trades, inspections, paying subcontractors and suppliers, and employer duties if anyone unlicensed is hired. A licensed general contractor takes those duties on under its own license, bond and insurance. Both paths are legal; the right one depends on your experience, your time and the job. Call 805-712-8993.

1. Two ways to run a build

What “owner-builder” and “general contractor” mean

The CSLB’s owner-builder note puts it simply: “owner/builder” describes a situation in which the homeowner becomes the general contractor. When you sign a building permit application as an owner-builder, the CSLB says, you assume full responsibility for all phases of your project and its integrity.

Its owner-builder responsibilities page lists what that covers in practice: pulling the permits, passing code and building inspections, ordering materials and making sure suppliers are paid, and supervising, scheduling and paying subcontractors.

A licensed general contractor does the same work as a business. For a home, that usually means a Class B General Building contractor. To be licensed, the CSLB notes, contractors must demonstrate knowledge of their craft, pass exams, be fingerprinted and bonded, and pass a background check. A licensee must also keep a current workers’ compensation certificate, or an exemption if it has no employees, on file with the CSLB under section 7125, and must list its license number on permits and contracts.

Neither path is better for everyone. The question is who will carry the responsibilities that every build has, and whether you have the time and background to carry them yourself.

2. The owner-builder exemption

What section 7044 allows, in plain terms

The Contractors State License Law does not apply to an owner who builds or improves a structure on their own property in the situations below. The full text is printed in the CSLB’s 2026 CSLB Law Book.

Path under section 7044Who does the workConditions in the statute
Owner doing the work, (a)(1)You personally, or your own employees paid wages as their only compensationNone of the improvements are intended or offered for sale
Owner contracting with licensed trades, (a)(2)Licensed contractors you hire directly, each licensed for its tradeFor single-family homes, no more than four structures intended or offered for sale in a calendar year; that limit does not apply if you contract with a general contractor for the construction
Homeowner improving a principal residence, (a)(3)The homeowner improving the home they live inWork done before sale; you lived in the home for the twelve months before the work was completed; and you have not used this paragraph on more than two structures more than once in any three-year period

Summarized from the text of Business and Professions Code section 7044 as printed in the CSLB 2026 Law Book, read October 17, 2026. Section 7044 also covers nonprofit mutual self-help housing programs, not shown here. General information, not legal advice.

The sale rules

The exemption is for owners building for themselves, not for sale. Section 7044(b) adds two presumptions that apply in actions under the license law:

  • Sale within one year. If the owner-builder sells or offers the structure for sale within one year after completion, the law presumes it was built for sale. That presumption is rebuttable: the owner can show it was not, but the burden of proof shifts to them.
  • Five or more. Selling or offering five or more structures within one year after completion is a conclusive presumption that they were built for sale.

The County of San Luis Obispo’s permit application states the practical effect in the declaration you sign: except for your personal residence, where you must have lived for at least one year before the work is completed, you cannot legally sell a structure you built as an owner-builder unless it was built in its entirety by licensed contractors. Under section 7044.01, a court can stop an owner-builder who is neither licensed nor exempt, at the request of a consumer affected by the violation, a licensed contractor, a district attorney or the Attorney General, among others.

If you might sell, refinance or move within a short time after finishing, talk to a real estate attorney before you check the owner-builder box.

3. What you sign in SLO County

The Owner-Builder Declaration, the Acknowledgment and the workers’ comp choice

State law (section 7031.5) requires every city and county that issues building permits to have the applicant sign a statement either that they are licensed, with the license number, or that they are exempt and why. In unincorporated San Luis Obispo County, Planning & Building handles this on its construction permit application and a separate form. The forms are on the County’s construction permit application forms page.

  • Owner-Builder Declaration. Signed under penalty of perjury on the application. You check whether you, or your employees paid wages as their only compensation, will do all or part of the work on a structure not intended or offered for sale; whether you are contracting exclusively with licensed contractors; or another exemption, with the reason.
  • Owner-Builder Acknowledgment (form BLD-1006). The County will not issue the permit until you have read and initialed twelve statements, signed the form and returned it. Among them: that you are the responsible party of record; that you can protect yourself by hiring a licensed contractor and having the permit filed in its name; that if you hire people other than licensed contractors you may be an “employer” under state and federal law, with registration, payroll tax, workers’ compensation, disability and unemployment duties; that you may be liable to later owners for latent defects if you sell; and that you will tell the County about any change to the information you gave.
  • Signature checks. The County asks for a copy of your driver license, notarization or other acceptable verification of the owner’s signature, and an agent cannot sign the Acknowledgment for you unless you first get approval from the County Building Official.
  • Workers’ Compensation Declaration. Also under penalty of perjury, you declare one of three things: that you hold a certificate of consent to self-insure, that you have and will keep workers’ compensation insurance under Labor Code section 3700 (with carrier and policy number), or that you will not employ anyone in a way that makes you subject to workers’ compensation law and will comply right away if that changes.

The County’s Consent of Property Owner form (BLD-1005) says permits are issued to a licensed contractor, or once an Owner-Builder Acknowledgment has been completed. If the plan changes partway through, the Change of Building Permit Record (BLD-1043) is how the County records a new contractor, a change to owner-builder or a new permit holder.

Inside city limits (for example Paso Robles, Atascadero or Arroyo Grande) the city building department issues the permit on its own application. The state declarations are the same, but the forms and steps differ, so ask the city which ones it uses (we confirm per jurisdiction). Our SLO County building permits guide explains who issues what. The same state rules apply in Monterey and Santa Barbara counties, again on local forms.

4. Workers, insurance and payroll

The employer question

This is the part of owner-building that surprises people most. The CSLB’s owner-builder responsibilities page says that if you use anyone other than a licensed subcontractor for the work, you may be considered an “employer.” Employers must register with the state and federal governments and handle income tax withholding, Social Security taxes, workers’ compensation insurance, disability insurance and unemployment contributions.

  • Workers’ compensation. The state Division of Workers’ Compensation says California employers must carry workers’ compensation insurance even if they have only one employee, and its employer fact sheet notes that failing to have it is a criminal offense. The County’s permit warning cites civil fines and the damages provided for in Labor Code section 3706 on top of the cost of compensation.
  • Homeowner’s insurance. The County’s Acknowledgment and the CSLB’s owner-builder risks page both warn that if a worker is hurt on your property, you could be asked to pay through your homeowner’s policy, and that the policy may not cover it. Ask your agent, in writing, what your policy covers during construction and whether you need a separate policy for the build.
  • Payroll. If you do become an employer, you would need to register as an employer with the EDD and follow its payroll steps; the CSLB also points owner-builders to the IRS, the U.S. Small Business Administration and the Franchise Tax Board.
  • Checking the trades you hire. If you hire licensed contractors, the County form says verifying their licenses and workers’ compensation status is your job. The CSLB license check shows both. A contractor with no employees can file an exemption, so if a crew shows up, ask how they are covered. The CSLB Law Book lists classifications that must carry workers’ compensation even without employees: concrete (C-8), warm-air heating and air conditioning (C-20), asbestos abatement (C-22), roofing (C-39) and tree service (C-61/D-49).

Hiring only licensed contractors, each with its own coverage, is how many owner-builders keep the employer question simple. It does not remove the job of checking each one.

5. Side by side

What an owner-builder carries, and what a general contractor carries

The work on a build is the same either way. What changes is who is responsible for it.

ResponsibilityOwner-builderLicensed general contractor
Name on the permitYou are the responsible party of recordThe contractor files the permit under its license number
Hiring, scheduling and supervising tradesYou, trade by tradeThe contractor, under one contract with you
Inspections and correctionsYou schedule inspections, meet the inspector and get corrections doneThe contractor
Ordering materials and paying suppliersYouThe contractor, with lien releases to you as it is paid
Workers’ compensation and payrollYours if you hire anyone who is not a licensed contractorThe contractor’s, for its own employees
License, bond and state oversightNo license needed under the exemption; CSLB complaint process applies to the licensed trades you hireLicensed, bonded and subject to CSLB discipline
Selling the homeSale rules and presumptions in section 7044 apply; you may answer to later buyers for defectsNo owner-builder sale limits
Your time on the jobDaily, from foundation to finalDecisions, selections and progress reviews

Based on the CSLB owner-builder pages and note, the County of San Luis Obispo Owner-Builder Acknowledgment (BLD-1006, 06/17/2025) and its construction permit application, read October 17, 2026.

One rule matters if you plan to hire help with management. Under section 7026.1, a person who acts as a consultant to an owner-builder by providing or overseeing a bid, or by arranging work schedules for contractors and maintaining oversight of the project, is treated as a contractor on home improvement work and needs a license. The CSLB’s owner-builder pages warn about unlicensed “consultants” who offer to guide owners through the owner-builder process for a fee. If you want a project manager, hire a licensed contractor for that role.

A second detail for new homes with fire sprinklers: section 7026.12 lets an owner-builder of an owner-occupied single-family home install the sprinkler system only if no more than two single-family homes on the same parcel are built within one year, the plans are approved and the local building authority inspects and approves the installation. Otherwise a contractor with the fire protection classification installs it.

6. Paying the trades

Liens when you are the one writing the checks

As an owner-builder, you are the one paying subcontractors and suppliers, so mechanics lien law lands on your desk directly. The CSLB’s homeowner’s guide to mechanics liens explains the safeguards. A few points change when there is no general contractor in the middle:

  • Every trade you hire is a prime contractor. The CSLB guide notes that a prime contractor is not required to send you a preliminary notice, because its contract must carry the Mechanics Lien Warning, yet it can still record a lien if unpaid. When you hire each trade directly, keep your own list of who is working, what each is owed and what has been paid.
  • Their suppliers and subcontractors may send notices. A preliminary notice is not a lien; it tells you who has potential lien rights. It can arrive up to 20 days after work or deliveries start. Check the list before each payment.
  • Releases with every payment. Collect a conditional release before you pay and an unconditional release after the payment clears, using the CSLB’s statutory release forms. Joint checks to a trade and its supplier are one of the simplest protections.
  • Notice of completion. Recording one with the county recorder when the work is done shortens the time claimants have to record a lien: the CSLB guide gives 60 days for a prime contractor and 30 for a subcontractor or supplier, instead of the usual 90.

Each trade contract is its own contract. Get each one in writing, with scope, payment schedule and changes defined; our fixed price vs cost-plus guide lists the questions that apply to any construction contract.

7. Which fits your project

When owner-builder can work, and when a general contractor usually fits

We talk with owners on both sides of this decision across Paso Robles, Templeton and the rest of the Central Coast. These are the factors that tend to decide it, in our experience:

  • Your construction background. The CSLB’s owner-builder risks page notes that unless you know construction, mistakes can be costly and take time to correct. Owners who have built before, or who work in a trade, are often well placed to run their own job.
  • Your time. Trades, deliveries and inspections mostly happen on weekdays. Someone has to be on site, answer questions and keep the sequence moving from foundation to final.
  • The size and complexity of the job. A shop, barn or modest remodel of the home you live in is a different scale from a large custom home on a hillside lot, on expansive clay, with a well and septic, or in a coastal or design-review area. Our guide to rural acreage covers several of those site questions.
  • Your lender. If a construction loan is part of the plan, ask the lender early whether it finances owner-builder projects and what it requires. Our financing page covers what lenders typically ask for.
  • Your plans for the property. The sale rules in section 7044 matter if you might sell soon after finishing.
  • Rebuilding after a loss. Owners rebuilding after a fire sometimes consider owner-building to move faster. Our wildfire rebuild guide covers that path, and the same exemption rules and forms apply.

There are middle paths, too. Some owners hire a licensed general contractor for the house and handle separate items themselves, such as an ADU or an addition later, under its own permit. If you split the work, ask the building department how each permit will be held before anyone starts.

8. Checklist

Before you check the owner-builder box

  1. Read section 7044 and decide which path applies: doing the work yourself, contracting with licensed trades, or improving your own residence.
  2. Be honest about the sale question: are you building to live in it, and for how long?
  3. Read the County’s Owner-Builder Acknowledgment (or your city’s version) before you apply, not at the counter.
  4. Decide who will do each part of the work, and whether anyone you hire would make you an employer.
  5. Talk to your insurance agent about workers’ compensation, liability and a builder’s policy for the construction period.
  6. Check every contractor’s license, bond and workers’ compensation status on the CSLB site, and keep a copy.
  7. Get a written contract from each trade, with scope, price, payment schedule and change orders spelled out.
  8. Set up a payment log with conditional and unconditional releases for each payment.
  9. Map the inspection sequence with the building department and plan who will be on site for each one.
  10. Get a price from a licensed general contractor for the same plans, so you are comparing real numbers, including the value of your own time.

How we help

If you are deciding between the two

  • A price from the plans. Send the drawings and we will put together a detailed general-contractor number, with allowances where selections are still open, so an owner-builder budget and ours can be compared on equal terms.
  • Straight answers. Some owners we talk with hire us for the whole build; others decide to run it themselves. Either way, we are glad to walk through the permit, the trades and the schedule with you.
  • Plans either way. Every permit needs a plan set. Our design studio, Harrod Drafting & Design, can draw the house, an addition or an ADU and prepare the permit set, whoever ends up building it.
  • Outside, too. Landscape and hardscape often end up as a separate contract on an owner-run job; our landscape company, Paso Robles Landscaping, can take that part.

Harrod Built is a family general contractor (CSLB #986950) based in Paso Robles, offering general contracting and design-build across San Luis Obispo, Monterey and Santa Barbara counties. Read more about how a job runs with us. Check any contractor with the CSLB license check.

FAQ

Common questions

Something else on your mind? Call Michael at 805.712.8993.

Can I be my own general contractor in California?

Yes. Under Business and Professions Code section 7044, a property owner can build or improve a structure on their own property without a contractor license if they do the work themselves or with employees paid wages, or if they contract directly with licensed trade contractors, as long as the structure is not intended or offered for sale. As the owner-builder, you are the responsible party on the permit for the whole project.

Can I sell a house I built as an owner-builder?

The exemption is for owners who are not building for sale. If you sell or offer the home for sale within one year after completion, section 7044 presumes it was built for sale, and you carry the burden of showing it was not. The County of San Luis Obispo’s declaration adds that, other than a personal residence you lived in for at least a year before completion, you cannot legally sell an owner-builder structure unless licensed contractors built all of it. Ask a real estate attorney before you sell.

Do I need workers’ compensation insurance as an owner-builder?

If anyone working for you is not a licensed contractor, you may be considered an employer, and California employers must carry workers’ compensation insurance even with one employee. On a County of San Luis Obispo permit you declare under penalty of perjury that you have coverage, are self-insured, or will not employ anyone in a way that makes the law apply. Licensed contractors you hire should carry their own coverage; check it on the CSLB website.

What forms does SLO County require from an owner-builder?

For a permit in unincorporated San Luis Obispo County, you sign the Owner-Builder Declaration and the Workers’ Compensation Declaration on the construction permit application, and you read, initial, sign and return the Owner-Builder Acknowledgment (BLD-1006) before the permit is issued, with a driver license copy, notarization or other verification of your signature. Cities in the county use their own forms.

Can an owner-builder hire someone to manage the project?

Yes, but under section 7026.1 a person who provides or oversees bids, or arranges schedules for contractors and oversees the project as a consultant to an owner-builder on home improvement work, counts as a contractor and needs a license. The CSLB warns owners about unlicensed consultants who offer to guide them through the owner-builder process for a fee.
