Owner-Builder Permits Explained

An owner-builder permit, sometimes called a homeowner permit, lets a property owner obtain a building permit and act as their own general contractor instead of hiring a licensed one. It is how many people legally finish a basement, build a deck, or even build a whole house themselves. The permit does not lower the code standard. The work gets the same plan review and inspections as a contractor’s job, and the owner becomes the person responsible for it.

The model International Residential Code (IRC) already assumes owners can apply. Section R105.1 says any “owner or owner’s authorized agent” who intends to build, alter, or repair a building, or to install or alter an electrical, gas, mechanical, or plumbing system, must first apply for and obtain the permit. Whether you can then do the work without a license comes from state contractor licensing laws, which usually exempt owners working on their own property, and from local rules about who may sign a trade permit. Confirm the rules with your local building department before you apply.

Who usually qualifies

Owner-builder eligibility commonly depends on these factors:

• You own the property. The name on the permit generally must match the recorded owner. Tenants and buyers under contract usually cannot pull owner-builder permits.
• It is your residence, or will be. Many laws limit the exemption to a one- or two-family home the owner occupies or will occupy. Rental properties, commercial buildings, and multifamily buildings often require licensed contractors.
• You are not building for sale or rent. Licensing exemptions are meant for owners improving their own home, and several states treat a quick sale as evidence you were building to sell.
• You will supervise or do the work. Many laws require the owner to personally perform or directly supervise the work.

What state laws say

Each state writes its own exemption. These four show the range.

Florida. Under Section 489.103(7), owners acting as their own contractor and “providing direct, onsite supervision themselves of all work not performed by licensed contractors” may build or improve one- or two-family residences or farm outbuildings for their own use, not offered for sale or lease. Commercial buildings qualify only up to a $75,000 cost. Proof of a sale or lease, or offering one, within 1 year after completion “creates a presumption that the construction was undertaken for purposes of sale or lease.” The owner must personally appear and sign the permit application. The permitting agency must give the owner a 12-item disclosure statement, and a copy of the owner’s driver license, a notarized signature, or other verification the agency accepts is required when the permit is issued. If the rules are violated, the agency must withhold final approval, revoke the permit, or pursue unlicensed-activity remedies. Electrical work has a parallel owner exemption in Section 489.503(6) for an owner who applies for the permit, supervises, and does the work on a single-family or duplex residence for their own use.

California. The Contractors State License Board’s owner-builder overview, which summarizes Business and Professions Code section 7044, says an owner-builder does not need a license when they do the work themselves or through their own employees paid wages only, and the structure is not intended for sale. An owner who contracts with properly licensed subcontractors may build single-family homes for sale, but no more than four in a calendar year. An owner who hires a licensed General Building (“B”) contractor has no limit. A homeowner improving their principal residence is also exempt if the work is done before any sale, they lived there for the 12 months before completion, and they have not used the exemption on more than two structures in any three-year period. One trade is off limits to all owners: well drilling under the C-57 classification.

Arizona. ARS 32-1121(A)(5) exempts owners who do the work themselves, with their own employees, or with licensed contractors, when the structure is intended for occupancy solely by the owner and not for sale or rent. Selling, renting, or offering to do either within one year after completion or after the certificate of occupancy is “prima facie evidence” the project was for sale or rent. The statute counts any arrangement where the owner receives money, goods, or labor in exchange as a sale or rental.

Texas. The state trade licensing laws carve out homeowners. Occupations Code Section 1301.051 says a property owner does not need a plumbing license “to perform plumbing in the property owner’s homestead.” Section 1305.003(a)(6) exempts electrical work “not specifically regulated by a municipal ordinance” performed in a dwelling by a person who owns and resides in it. Cities still require trade permits and inspections, and Austin’s rules below show how a city narrows the exemption.

How the rules differ by city

• Miami-Dade County, FL. The county’s homeowner permit page says homeowners may act as owner-builders, pull permits, do the work themselves, and hire their own licensed subcontractors, but must sign a form acknowledging their owner-builder responsibilities before the permit is issued. The building permit application must be notarized and signed by the property owner.
• Austin, TX. Unlicensed homeowners can do electrical, mechanical, and plumbing work only under a Homestead Permit. You need a homestead exemption on file with the county appraisal district, and the work must be in your homestead and principal residence. The permit cannot cover the main electric service, reclaiming and charging a ducted system containing refrigerant, liquefied petroleum plumbing systems, or an auxiliary water system. Only the permit holder may do the work, the permit cannot be transferred, and you cannot get another homestead permit for a different residence within 12 months. Inspectors can ask for photo ID and proof of residence and ownership.
• Phoenix, AZ. The city’s residential permit application has the owner declare the property is for their sole occupancy and will not be offered for sale or rent within one year of completion, citing ARS 32-1121.A.5. Phoenix’s permit issuance requirements add that any work on single-family property done by someone other than the owner must be done by a licensed contractor whenever a permit is required or the cost is more than $1,000, including labor and materials.

What you take on as the owner-builder

Pulling the permit yourself makes you the responsible party of record. California’s licensing board puts it plainly: when you sign as an owner-builder, “you assume full responsibility for all phases of your project and its integrity.” That typically means:

• Code compliance. You must build to the adopted codes and correct anything an inspector flags.
• Scheduling inspections. IRC R109.3 makes it the permit holder’s duty to notify the building official when work is ready and to provide access. Under R109.4, work cannot be covered or concealed until it is approved.
• Keeping the permit alive. Under IRC R105.5, a permit becomes invalid if work does not start within 180 days of issuance or if more than 180 days pass between inspections, unless the official grants a written extension. Slow owner-builder projects run into this often.
• Supervising and paying anyone you hire. Florida’s disclosure statement and California’s licensing board both warn that unlicensed workers can make you their employer, responsible for income tax withholding, Social Security taxes, workers’ compensation, and in California, disability and unemployment insurance.
• Insurance. Florida’s disclosure warns that your homeowner’s insurance may not cover injuries to unlicensed workers on your property. Ask your insurer before you start, and consider builder’s risk coverage for larger projects.
• Financing and resale. Many construction lenders will not finance owner-built homes. Buyers, lenders, and appraisers may ask who did the work, and a closed permit with passed inspections helps.

A common scam to avoid

Florida’s disclosure statement says “it is a frequent practice of unlicensed persons to have the property owner obtain an owner-builder permit that erroneously implies that the property owner is providing his or her own labor and materials.” California’s licensing board warns about “consultants” or unlicensed individuals who try to talk you into becoming an owner-builder to save money. The arrangement puts all responsibility on you and removes the protections you would have with a licensed contractor. Florida’s statement notes that if you contract with an unlicensed person, the state licensing board may be unable to help with your losses and your only remedy may be civil court.

Owner-builder checklist

• Confirm you are on the deed and that the property is (or will be) your residence.
• Read your state’s owner-builder exemption, including any sale or rental waiting period.
• Ask which trade permits a homeowner may hold, and whether you need a homestead exemption, test, or affidavit.
• Prepare a site plan, floor plan, and construction details; ask whether plans must be sealed by an architect or engineer.
• Sign the owner-builder disclosure, declaration, or acknowledgment form; bring photo ID and be ready for notarization or in-person signing.
• Verify the license and insurance of every subcontractor, and have each pull their own trade permit if required.
• Call your insurer about worker injuries and builder’s risk coverage.
• Post the permit card, request each inspection before covering work, and track the 180-day activity window.
• Keep the final inspection record and closed permit with your property documents.

How to apply as an owner-builder

The process mirrors any permit application. Confirm eligibility, prepare drawings, complete the owner-builder form your jurisdiction requires, and pay the permit fees, which are based on the work, not who does it. See building permit cost. The how to apply for a building permit guide covers the general process, and building inspection stages explains inspections.

Questions to ask your building department

• Can I pull an owner-builder permit for this property and this type of work?
• Which trades must be done by a licensed contractor here?
• Do you require an affidavit, disclosure form, notarized signature, test, or proof of residency or homestead?
• Can I hire licensed subcontractors under my permit, and do they need their own permits?
• Are there restrictions on selling or renting the property after completion?
• Do I need plans prepared by a licensed architect or engineer for this project?

When hiring a contractor makes more sense

Owner-builder permits work well for projects you understand and can supervise closely. Consider a licensed contractor when the work involves structural changes, gas, service panel upgrades, or connections to public utilities, which several cities exclude from homeowner permits anyway. Also consider one when you need financing, plan to sell or rent within a year or two, or cannot be on site daily. Work done without a permit, or with a permit that is never closed, can create problems later. See the unpermitted work guide for how that plays out.
