Short answer: Exchange lists 8 renovation and remodeling contractors in Pennsylvania. Pennsylvania has no statewide general contractor license; instead, the Home Improvement Consumer Protection Act requires anyone doing $5,000 or more of home improvement work a year to register with the Office of Attorney General and carry at least $50,000 bodily-injury and $50,000 property-damage liability cover. Contracts over $500 must be written. Since January 1, 2026, the Uniform Construction Code enforces the 2021 International Codes as amended.
- Registering body
- Pennsylvania home improvement contractors register with the Office of Attorney General under the Home Improvement Consumer Protection Act (Act 132 of 2008).
- Registration threshold
- Registration is required once a contractor performs $5,000 or more of home improvement work in Pennsylvania in a year; the fee is $100 and registration runs two years.
- Minimum insurance
- Pennsylvania registrants must carry at least $50,000 bodily-injury and $50,000 property-damage liability coverage or file a self-insurance attestation.
- Building code
- Pennsylvania's Uniform Construction Code moved to the 2021 International Codes, as amended by the Review and Advisory Council, on January 1, 2026.
- Lien deadline
- Under the Pennsylvania Mechanics' Lien Law a claim must be filed within six months of the claimant's last work, and claims under $500 are not allowed.
- Dig notice
- Pennsylvania excavators must contact PA One Call at least three business days before digging, including for footings, decks and drainage on renovation jobs.
Who licenses renovation and remodeling contractors in Pennsylvania?
Pennsylvania does not issue a statewide general contractor or remodeler license, which surprises owners arriving from states with a contractor board. The Commonwealth's main control on residential renovation is registration, not licensing: the Home Improvement Consumer Protection Act, Act 132 of 2008, requires anyone who owns or operates a home improvement business, or who offers or agrees to perform home improvements, to register with the Office of Attorney General's Bureau of Consumer Protection. Registration is not an exam or a competency check. It is a disclosure and insurance gate that gives consumers a traceable registration number and gives the Attorney General enforcement leverage.
The registration duty attaches once a contractor's home improvement work reaches $5,000 in a year; smaller operators below that figure are exempt, as are home improvement retailers with a net worth of $50 million or more, although the subcontractors and installers those retailers send into homes still have to register. New home construction is outside the Act entirely, so a builder putting up a new house is not a home improvement contractor for that job, but the same firm finishing a basement or adding a sunroom to an existing house is.
The application costs $100, paid to the Commonwealth of Pennsylvania, and registrations are valid for two years before biennial renewal. Applicants disclose owners and associated businesses, supply identification, and submit a certificate of insurance. Renewing contractors keep the same PA registration number, which is why a long-established remodeler's number is a useful sign of continuity: a firm that has changed names or numbers repeatedly deserves a closer look.
Above the state layer sit city licenses. Philadelphia's Department of Licenses and Inspections requires a city contractor license for most construction, demolition and repair businesses, and the City of Pittsburgh requires building permit applications to come from a city-licensed contractor unless an owner-occupant of a one- or two-family dwelling is doing the work without employees. Trade work such as electrical and plumbing is licensed locally in those cities rather than by the state, so a kitchen or bath remodel in Philadelphia or Pittsburgh typically involves both a registered remodeler and separately licensed trade contractors.
What must a Pennsylvania home improvement contract contain?
The Act is unusually prescriptive about paperwork. Any home improvement contract with a total cash price over $500 must be in writing and signed by both the homeowner and the contractor. The Attorney General's guidance lists the elements it expects to see: the total price, estimated start and completion dates, a description of the work, written notice of the homeowner's right to cancel, and the contractor's registration number displayed clearly, together with the Bureau of Consumer Protection's toll-free number so the owner can check it.
Pennsylvania gives owners a three-day right to cancel, using the cancellation notice language set out in Section 201-7 of the Unfair Trade Practices and Consumer Protection Law. Where the owner was not properly told about that right, the Attorney General warns the contract may be voidable even after three days have passed, which is a serious commercial risk for a remodeler who has already ordered cabinets or started demolition. Genuine emergency work has a separate waiver route under the same section.
Time-and-materials work is allowed but constrained. If a renovation is priced on time and materials, the contract must include an initial written cost estimate, a statement that costs may not exceed that estimate by more than 10 percent, the total potential cost, and a requirement that any increase beyond that ceiling be approved through a signed written change order. Owners comparing bids for a gut renovation of an older house, where hidden conditions are common, should look for this language rather than an open-ended cost-plus arrangement.
On money up front, the Act limits deposits on projects priced above $5,000. The Attorney General's guidance points to a down payment of one-third of the total contract price, or one-third plus the cost of special-order materials, as the benchmark. The law does not dictate how the balance is paid, so the practical norm in Pennsylvania is a payment schedule tied to milestones such as rough-in inspections, drywall and final, with the last payment held until the municipal final inspection is passed.
Which licenses, permits and registrations apply in Pennsylvania?
| Licence / permit / registration | Issued by | Who needs it | Key threshold or rule |
|---|---|---|---|
| Home Improvement Contractor registration (HICPA) | Pennsylvania Office of Attorney General | Anyone performing home improvements on residential property in Pennsylvania | Required at $5,000 or more of work a year; $100 fee; two-year term; $50,000/$50,000 liability minimum |
| UCC building permit | Municipal code office or certified third-party agency (Department of Labor and Industry in opt-out municipalities for commercial work) | Structural, egress-changing and most trade work on homes and buildings | 2021 International Codes as amended, effective January 1, 2026; siding, repairs and non-structural alterations excluded unless a local ordinance says otherwise |
| Philadelphia contractor license | Philadelphia Department of Licenses and Inspections | Construction, demolition and repair businesses in Philadelphia, except firms working only on existing one- and two-family homes | $126 a year; $500,000 general liability; OSHA 30 supervisor trained within five years |
| Pittsburgh contractor license | Pittsburgh Department of Permits, Licenses and Inspections | Contractors applying for building permits in the City of Pittsburgh | Owner-occupants of one- or two-family dwellings using no employees are exempt |
| EPA lead-safe firm certification (RRP) | U.S. Environmental Protection Agency | Firms disturbing paint in pre-1978 homes and child-occupied facilities | Pennsylvania is not an EPA-authorized state, so the federal rule applies directly |
| PA One Call ticket | Pennsylvania One Call System, enforced by the Public Utility Commission | Anyone excavating, including footings and trenches | Notice at least three business days before digging |
How do I check a renovation contractor in Pennsylvania before I sign?
7 checks, in order, using the Pennsylvania registers and rules described on this page:
- Ask for the contractor's PA home improvement registration number and confirm it with the Attorney General's Bureau of Consumer Protection at 1-888-520-6680 before signing.
- Check that the written contract, required for any job over $500, shows the registration number, total price, start and completion dates, scope, and the three-day cancellation notice.
- Request a current certificate of insurance showing at least $50,000 bodily-injury and $50,000 property-damage liability, and in Philadelphia at least $500,000 general liability with workers' compensation.
- In Philadelphia or Pittsburgh, look up the firm's city contractor license and the separate electrical or plumbing licenses of any trade subcontractors named in the bid.
- Confirm with your municipal code office or third-party agency which UCC permits the job needs under the 2021 codes in force since January 1, 2026, and make sure the contractor, not you, is the applicant.
- For pre-1978 homes, ask for the firm's EPA RRP certification and the name of its certified renovator; for basements or additions, ask whether a DEP-certified radon installer will be used.
- Keep deposits within the one-third benchmark on projects over $5,000 and hold final payment until the municipal final inspection, remembering that paying the contractor in full protects an owner-occupied home from subcontractor liens.
Which building code applies to renovations in Pennsylvania right now?
Pennsylvania enforces construction standards through the Uniform Construction Code, created by Act 45 of 1999 and administered by the Department of Labor and Industry. The UCC adopts the International Code Council family by reference, filtered through the Review and Advisory Council created by Act 106 of 2008, which reviews each new ICC edition before it is adopted. That process explains why Pennsylvania tends to adopt codes later than the publication cycle and with Pennsylvania-specific deletions.
The current change is fresh. The triennial update moving the UCC to the 2021 International Codes, as amended, was approved by the Independent Regulatory Review Commission on October 16, 2025, published November 8, 2025, and took effect January 1, 2026. Until that date the 2018 I-Codes, effective February 14, 2022, applied. The UCC lets a permit be issued under the code in force when a design or construction contract was signed, provided the application is filed within six months of the new code's effective date, so that grandfathering window has now closed for nearly all projects and new renovation permits are reviewed under the 2021 editions.
One wrinkle matters for commercial and multifamily renovation. The Commonwealth Court permanently enjoined the 2021 accessibility provisions on October 26, 2022, in Pennsylvania Builders Association v. Department of Labor and Industry, so the 2018 accessibility requirements continue to apply while the rest of the code moves on. A remodeler converting a storefront or renovating common areas in an apartment building should be designing to that split.
Enforcement is local. More than 90 percent of Pennsylvania's 2,562 municipalities administer the UCC themselves, either with their own staff or through certified third-party agencies. In municipalities that opted out, the Department of Labor and Industry handles commercial enforcement and residential work is inspected by third-party agencies hired by the owner or contractor. Owners should therefore confirm early which code official or third-party agency will review their project, because plan-review practices and inspection scheduling vary sharply from township to township.
Which Pennsylvania renovation jobs need a building permit?
The UCC carves out several categories of residential work from its permit requirements, and those exclusions shape remodeling scopes across the state. Under 34 Pa. Code section 403.1(b), alterations to residential buildings that make no structural change and do not alter means of egress are excluded, as are ordinary repairs and the installation of aluminum or vinyl siding over an existing residential building. Replacing existing windows or doors is treated as non-structural even when it involves the minor framing changes needed to fit the new unit.
Detached accessory structures such as sheds, detached garages, carports and greenhouses serving a detached one-family dwelling are excluded when their building area is under 1,000 square feet. That threshold is far larger than the 200-square-foot style limits found in many other states, and it explains why Pennsylvania homeowners often build sizeable garages with only zoning approval.
The exclusions are not universal. Each one is subject to municipal ordinances: municipalities that had building codes in place before the UCC and kept stricter provisions, and those that adopted local amendments through the UCC's own procedure, can still require permits for work the state list excludes. In practice, two neighboring townships can treat the same deck, basement or porch project differently, so the state exclusion list is a starting point rather than the final answer.
For an owner, the takeaway is simple: anything structural, anything that changes egress such as a new bedroom in a basement or attic, and most electrical, plumbing and mechanical work will need a permit, and the cosmetic exclusions vary by municipality. A Pennsylvania remodeler who cannot tell you, in writing, which permits the job requires from the specific borough or township is not someone to hire for a significant renovation.
How do Philadelphia and Pittsburgh regulate renovation contractors in Pennsylvania?
Philadelphia layers its own requirements on top of state registration. A business doing construction, demolition or repair work that does not need a specialized company license must hold a Philadelphia contractor license from the Department of Licenses and Inspections. The license costs $126 a year, requires a Business Income and Receipts Tax account and a Commercial Activity License, and requires the firm to be current on city taxes. Specialized company licenses cover electrical, plumbing, fire suppression and complete demolition work.
The city's insurance floor is substantially higher than the state's. Licensed contractors must carry general liability of $500,000 per occurrence, automobile liability of $300,000, and workers' compensation at $100,000 per accident, $100,000 per employee and a $500,000 policy limit. Each license must also identify project supervisors who hold an OSHA 30 certificate completed within the past five years, and a supervisor may work for only one licensed company.
There is an important carve-out for remodelers. Philadelphia exempts businesses that work only on existing one- and two-family dwellings and do no work requiring a special trade license from the city contractor license; those firms register with the Attorney General under the Home Improvement Consumer Protection Act and submit that registration to the city instead. A rowhouse kitchen remodeler may therefore legitimately hold only a state HICPA number, while a firm renovating a mixed-use building on a commercial corridor needs the full city license.
In Pittsburgh, building permits are issued through the Department of Permits, Licenses and Inspections, and applications must come from a contractor licensed by the city unless the work is performed by the owner and occupier of a one- or two-family dwelling using no employees. Contractors also file annual registration information with the city. Allegheny County's older housing stock, steep lots and retaining walls mean structural and drainage permits come up more often in Pittsburgh renovations than in flatter parts of the state.
What lien and payment rules protect Pennsylvania homeowners and contractors?
Pennsylvania's Mechanics' Lien Law of 1963 governs liens on improved property. A claim cannot be filed for less than $500, and every claimant must file in the county Court of Common Pleas within six months of its last work on the project. Subcontractors must give the owner a formal notice of intent at least 30 days before filing, and subcontractors working on alteration or repair projects must also give a preliminary notice before their work is completed. The filed claim must then be served on the owner within one month.
Owner-occupied homes get a powerful defense. Where the property is the owner's or tenant's residence and the owner has paid the general contractor the full contract price, a subcontractor cannot enforce a lien against the house. Third-tier subcontractors and suppliers have no lien rights at all. On most residential projects, general contractors can also obtain lien waivers from their subcontractors, something the statute generally prohibits on larger commercial jobs unless a payment bond is posted.
The State Construction Notices Directory, an online statewide registry, applies to projects valued at more than $1.5 million. On those projects the owner may file a notice of commencement and subcontractors file notices of furnishing, so it rarely affects a single-family remodel but does reach large condominium or historic-building renovations in Philadelphia and Pittsburgh.
Payment timing between contractors is governed by the Contractor and Subcontractor Payment Act, 73 P.S. section 501 and following, which was significantly amended effective October 10, 2018. Contractors must pay subcontractors their share within 14 days of receiving payment, withholding for deficient work requires written notice with a good-faith reason, and late payments carry interest of 1 percent per month plus a 1 percent monthly penalty and attorney's fees. Most of the 2018 provisions cannot be waived by contract, so a remodeling subcontract that tries to bar a sub from suspending work for nonpayment is unenforceable.
How do Pennsylvania's housing stock and climate affect renovation work?
Pennsylvania renovation is dominated by old buildings. Philadelphia's rowhouses, Pittsburgh's hillside frame houses, and stone farmhouses across Lancaster, Chester and Bucks counties all bring shared party walls, rubble stone foundations, balloon framing and legacy wiring that must be dealt with before modern finishes go in. Party-wall work in rowhouse blocks needs coordination with neighbors and careful attention to fire separation and roof flashing at shared parapets.
Radon is a statewide issue rather than a regional one. The Department of Environmental Protection reports that about 40 percent of Pennsylvania homes test above the EPA action level of 4.0 picocuries per liter. Basement finishing, foundation repair and additions are natural moments to test and, where needed, install a mitigation system, and DEP maintains lists of state-certified radon testing firms and mitigation installers. Owners should ask whether the remodeler subcontracts mitigation to a certified installer rather than improvising a fan and pipe.
Lead paint is near-universal in pre-1978 housing, and Pennsylvania has not taken over the federal program, so the U.S. EPA's Renovation, Repair and Painting rule applies directly. Firms disturbing painted surfaces in pre-1978 homes must be EPA-certified and use certified renovators and lead-safe work practices. Philadelphia adds its own lead requirements for rental properties, so remodelers working for landlords there should understand both regimes.
Freeze-thaw cycles and heavy, wet snow drive roofing, masonry and drainage work. Ice dams on older, poorly insulated attics, spalling brick on north-facing walls, and wet basements from saturated clay soils are the routine Pennsylvania renovation calls. Under the 2021 code cycle now in force, insulation and air-sealing upgrades during an attic or wall renovation should be planned with the code official, because Pennsylvania adopts the ICC energy provisions only as amended by the Review and Advisory Council.
How should you check a renovation contractor's workforce and safety record in Pennsylvania?
Worker classification is a construction-specific issue in Pennsylvania. The Construction Workplace Misclassification Act, Act 72 of 2010, sets a strict test for treating construction workers as independent contractors and is enforced by the Department of Labor and Industry. A remodeler who pays most of its crew as 1099 contractors without meeting that test is exposing the job, and potentially the owner, to wage and workers' compensation disputes.
Workers' compensation coverage is mandatory for Pennsylvania employers, and the Philadelphia contractor license sets specific minimum limits for it. Ask for a certificate naming you as certificate holder and check that the policy period covers the full project. For HICPA registration the Attorney General requires proof of liability coverage, but owners should independently confirm the policy is still active, because registrations run two years and insurance can lapse in the meantime.
Safety training is another differentiator. Philadelphia's OSHA 30 requirement for supervisors means city-licensed firms have at least one trained supervisor on staff. Outside Philadelphia there is no equivalent state rule for residential remodelers, so asking who will supervise the job, what training they have, and how fall protection will be handled on roofs and multi-story rowhouse facades is a fair screening question.
Excavation is regulated separately. Pennsylvania's PA One Call system must be contacted at least three business days before any excavation, which includes deck footings, fence posts, drainage trenches and additions, and the Pennsylvania Public Utility Commission enforces the damage prevention rules. A remodeler planning to dig without a One Call ticket is creating a safety and liability problem on your property.

Frequently asked questions
Is there a contractor license I can look up for a remodeler in Pennsylvania?
Not at state level. Pennsylvania registers home improvement contractors through the Attorney General rather than licensing them, so the number to check is the PA registration number. It proves the business disclosed its owners and showed insurance, not that it passed an exam. Philadelphia and Pittsburgh run their own contractor licenses, and plumbers and electricians are licensed locally, so the right lookup depends on where the house is.
Can I cancel a home improvement contract after signing it in Pennsylvania?
Yes. Homeowners have three days to cancel a home improvement contract, and the contractor must give written notice of that right in the contract. If the notice was missing or defective, the Attorney General says the contract may be voidable even after the three days. True emergency repairs can proceed sooner if the homeowner signs the waiver allowed under the consumer protection law.
How large a deposit can a Pennsylvania contractor ask for?
For projects over $5,000 the Home Improvement Consumer Protection Act limits deposits, and the Attorney General's benchmark is one-third of the total contract price, or one-third plus the cost of special-order materials such as custom cabinets or windows. The balance is negotiable, so tie the remaining payments to completed stages and passed inspections rather than calendar dates.
Does a small handyman need to register with the Attorney General?
Only if their home improvement work reaches $5,000 in a year. Below that level an individual is exempt, though they still need any local permits and licenses. Owners hiring someone for a bathroom, deck or kitchen should assume the job alone may push the worker over the threshold and ask for a registration number anyway.
Which code edition will my 2026 renovation permit be reviewed under?
New Pennsylvania permit applications are reviewed under the 2021 International Codes as amended by the Review and Advisory Council, which took effect statewide on January 1, 2026. Projects whose design or construction contracts were signed earlier could use the 2018 codes only if the permit application went in within six months. Accessibility provisions remain on the 2018 edition because the 2021 accessibility rules were enjoined in 2022.
Can my contractor's subcontractor put a lien on my house in Pennsylvania?
On an owner-occupied home, not if you have paid the general contractor the full contract price. Subcontractors must also give a formal 30-day notice of intent before filing and must file within six months of their last work, and lien claims under $500 are not allowed. Keep proof of every payment and request lien waivers from the general contractor at each draw.
Do I need to worry about radon when finishing a basement in Pennsylvania?
It is worth testing first. DEP estimates about 40 percent of Pennsylvania homes exceed the EPA action level of 4.0 picocuries per liter, and finished basements turn that air into living space. A DEP-certified tester can confirm levels, and if a system is needed, routing the vent pipe before walls and ceilings close is much cheaper than retrofitting it later.
