Lower Merion protects more of its building stock than almost any township in Pennsylvania, and the penalty for getting a demolition wrong is restoration at the owner’s cost, secured as a lien.
The township enforces the statewide code with its own staff from the Building and Planning Department on Lancaster Avenue in Ardmore. What sets it apart from comparable Montgomery County townships is the depth of its historic framework: a survey completed in 1991 identified more than eighty potential historic districts, and the resulting protections reach well beyond the formally designated districts.
Scope: Lower Merion Township in Montgomery County. Narberth Borough is a separate municipality entirely surrounded by the township and permits its own territory.
There are two historic bodies here and they do not overlap. The Historical Architectural Review Board reviews exterior alterations, new construction, demolition and signage inside the local historic districts. A separate Historical Commission reviews the same categories for properties on the township’s Historic Resource Inventory that are not in a local district.
What requires a building permit in Lower Merion Township?
Pennsylvania builds on a single statewide code — the Uniform Construction Code (UCC) — adopted under the Pennsylvania Construction Code Act (Act 45 of 1999) and maintained by the Department of Labor and Industry with its Uniform Construction Code Review and Advisory Council. The UCC adopts the International Code Council model codes; the 2021 ICC series took effect as the UCC on January 1, 2026, and permit applications on or after July 1, 2026 must comply with it. More than nine in ten of Pennsylvania’s municipalities administer and enforce the UCC locally — through their own code officials or a certified third-party agency — so the first question in Lower Merion Township is who enforces the code for the parcel and how they take a submission.
Permit required
- New commercial, multi-family and residential construction, additions and change of occupancy
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Electrical work — services, panels, circuits, solar and EV charging — under the UCC and the referenced National Electrical Code
- Plumbing and gas work under the UCC, pulled by a locally licensed trade where the municipality requires one
- Mechanical and HVAC change-outs, and work affecting the energy code envelope
- Re-roofing above the exempt scope, pools, signs, and demolition
Often exempt
- Minor repairs and maintenance replacing materials in kind
- Small accessory structures below the code threshold, where zoning allows
- Painting, flooring, cabinetry and other finish work
- Like-for-like fixture or appliance swaps with no alteration to wiring or piping
Local amendments, fee schedules and the choice of third-party agency differ from one municipality to the next, so an exempt list from a neighbouring township is not reliable. An exemption from a building permit is never an exemption from zoning, the energy code, or an electrical or plumbing permit. Confirm scope with the Building and Planning Department before work starts.
The statewide layers that apply everywhere
Two Pennsylvania features catch projects owners assume are simple. First, enforcement is a local choice: a minority of municipalities have opted out of local enforcement, in which case the Department of Labor and Industry enforces the commercial code and residential construction is not locally enforced — though zoning and other permits still apply. Second, the 2021 accessibility provisions of the International Codes remain enjoined statewide, so the 2018 accessibility standards still apply. Floodplain administration applies along the state’s rivers, and snow loading is a live structural constraint. Lower Merion carries a township-wide Historic Resource Inventory alongside its local historic districts, and demolishing an inventoried resource in violation of the ordinance obliges the owner to restore it — with the township able to perform the restoration itself and charge the cost plus an administrative fee as a municipal lien against the property.
Who handles permitting in Lower Merion Township?
Building permits, plan review, zoning and land development all sit with the Building and Planning Department at the township building in Ardmore, with the Building Regulations Division handling construction permits and inspections.
| Detail | Information |
|---|---|
| Authority | Lower Merion Township Building and Planning Department |
| Division | Building Regulations — construction permits and inspections |
| Address | Township Building, 75 East Lancaster Avenue, Ardmore, PA 19003 |
| Telephone | 610-645-6200 |
| Historic districts | Historical Architectural Review Board; certificate of appropriateness required |
| Historic inventory | Historical Commission; properties on the inventory outside local districts |
| Enforcement route | Township staff; Lower Merion enforces the code itself |
| Contractor credential | Township contractor licensing under the township code, plus state home improvement registration |
The two historic bodies were created twenty years apart and serve different populations of property. The review board, created in 1980, has nine members appointed by the Board of Commissioners and reviews applications within the local historic districts; work there needs a certificate of appropriateness before it can proceed. The commission, created in 2000, has seven members and reviews properties on the Historic Resource Inventory outside those districts. Design guidelines finalised in 2022 govern the substance of both reviews. Separately, the township runs a property resale certification: an application is filed ahead of settlement and the certificate confirms that sidewalks and kerbs are sound, house numbers are visible from the street and smoke detectors are installed, with a lower fee where the application arrives twenty or more days before settlement.
Permit types
Residential permits
Residential work here runs through large older houses across the Main Line, many of them inventoried as historic resources even where they are not inside a designated district. Alterations, additions, demolitions and signage all draw a historic question before they draw a code one. Floodplain parcels pick up a further layer: improvements in the Floodplain District are subject to the floodplain overlay provisions, and grading or a fence within the floodplain requires a zoning permit in its own right.
How Pennsylvania contractor credentials work
Pennsylvania does not license general contractors at state level — there is no state contractor licence, exam or board. Instead, under the Home Improvement Consumer Protection Act (HICPA), any contractor performing five thousand dollars or more of residential home improvement in a year must register with the Pennsylvania Office of Attorney General. Registration is administrative, not a skills licence, and by itself it does not grant permit-pulling authority.
In Pennsylvania the state registers home improvement contractors; the municipality licenses the trades. HICPA registration with the Attorney General is required for residential work, but electrical, plumbing and HVAC licensing is a local matter and several cities and counties — Philadelphia, Pittsburgh, Allegheny County, Allentown, Erie, Reading and Scranton among them — add their own contractor licences. Confirm what the Building and Planning Department requires for the parcel, along with insurance coverage.
Commercial permits
Commercial work along the Lancaster Avenue corridor and the township’s business districts is reviewed against the 2021 editions with accessibility on the 2018 standards, alongside zoning, land development and, where the property is inventoried or in a district, historic review. Change in use and change in tenant have their own application route, separate from the construction filing.
Licenses, trade classifications and design professionals
Practically, three credential layers appear on Pennsylvania projects: HICPA registration with the Attorney General on residential home improvement; separately licensed electrical, plumbing and HVAC trades, licensed by the municipality rather than the state; and, on commercial and larger residential work, drawings sealed by a Pennsylvania-licensed architect or professional engineer. Confirm what the Building and Planning Department requires for the specific building before filing.
Lower Merion Township permit costs and fees
Lower Merion sets its own fee schedule by permit type and collects the state Uniform Construction Code surcharge with the permit. Zoning permits, historic review and the resale certification carry separate charges, and the resale certification fee itself is tiered on how far ahead of settlement the application is filed.
| Fee component | How it works |
|---|---|
| Building permit | Based on project valuation or square footage; set by the municipality or its third-party agency |
| Plan review | A percentage of the permit fee or a flat charge, at submittal or by the third-party agency |
| Trade permits | Separate electrical, plumbing and mechanical fees under the local schedule |
| UCC state surcharge | The Uniform Construction Code education and administration fee, collected with the permit |
| Zoning and use | Zoning, use-and-occupancy and, in some places, contractor-licence fees |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
Pennsylvania fees are substantially local: the municipality or its certified third-party agency sets the building-permit and plan-review charge, and the state adds only a modest Uniform Construction Code surcharge collected with the permit. Where a municipality uses a third-party agency, that agency’s fee schedule applies. A figure from a neighbouring municipality is not reliable — ask the Building and Planning Department for the schedule in force on your filing date.

Trade permits and who may pull them
Trade permits are separate from the building permit and, on projects that require one, generally cannot be issued until the building permit is in place. Each trade follows its book within the Uniform Construction Code, and is tied to a contractor holding whatever trade licence the municipality issues — which is not portable across municipal lines.
Pennsylvania runs the trades on local licences. Electrical, plumbing and HVAC credentials are issued by municipalities and, in some cases, counties rather than the state, so a licence recognised in one jurisdiction may carry no weight in the next and the permit may have to be pulled by a differently licensed contractor. Confirm both the permit and the licence with the authority that issues it.
- Electrical work follows the UCC and the referenced National Electrical Code, under a locally licensed electrician where required.
- Plumbing work follows the UCC plumbing provisions, under a locally licensed plumber where required.
- Mechanical work follows the UCC mechanical and energy provisions.
Permit required
- Service installations, panel upgrades, new circuits, solar PV and EV chargers
- New plumbing, repipes, water heater change-outs, fixtures, backflow and gas piping
- HVAC installation and change-out, ductwork, venting and commercial kitchen exhaust
- Sprinkler, standpipe and fire alarm work on commercial and multi-family structures
Typically exempt
- Replacing a fixture, switch, receptacle or light with no alteration to wiring or piping
- Clearing a stoppage without replacing or rearranging concealed piping
- Filter, thermostat and routine component service
- Like-for-like appliance repair that does not alter the connection
How to apply for a Lower Merion Township building permit
Establish whether the property sits in a local historic district, on the Historic Resource Inventory, or neither. The answer determines which of the two bodies reviews the work and on what timetable.
Demolishing an inventoried resource in violation of the ordinance obliges the owner to restore it, and the township may perform the restoration and charge the cost plus an administrative fee as a municipal lien against the property.
A zoning permit is required for a range of improvements in its own right, including grading or a fence within the floodplain, and no use may be established or changed until one is obtained.
Submit through the Building Regulations Division with the drawings, the zoning approval and any certificate of appropriateness. There is an after-hours drop box for applications and plans.
If a sale is in prospect, file the property resale certification application ahead of settlement; the certificate takes thirty to sixty days and the fee is lower when the application arrives twenty or more days before settlement.
Schedule the milestone inspections as the work reaches them and close out the permit rather than leaving it open against the property record.
Review, corrections and what actually causes delay
In Pennsylvania, the first cause of delay is uncertainty over who enforces the code — filing with the municipality when it uses a certified third-party agency, or assuming a permit is required in a municipality that has opted out of residential enforcement. After that come a missing HICPA registration or local trade licence, energy-code and plan documentation, and, along the state’s rivers, floodplain requirements that were not addressed up front. Build the plan-review time into the schedule and confirm the checklist with the Building and Planning Department before filing.
Approvals do not stay live indefinitely. A Pennsylvania building permit carries a validity period and can expire if work does not start or stalls between inspections. On phased or financed work, keep the permit active with periodic progress inspections and confirm the expiry window before it passes.
Inspections in Lower Merion Township
Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and energy-code compliance, fire systems on commercial work, and final, with a use-and-occupancy certificate before the building is used. Lower Merion inspects through the construction sequence, and the property resale certification is a separate process running on its own thirty to sixty day timetable ahead of settlement rather than as part of the construction final.
Pennsylvania inspections are keyed to the code edition in force when the permit issued, and are carried out by a certified code official — the municipality’s own inspector, its certified third-party agency, or the city department in Philadelphia and Pittsburgh. Keep the approved plans and the energy-code documentation on site for the inspector to check against, and confirm the notice the Building and Planning Department needs and its inspection windows.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, energy-code documentation and your correction responses available on site.
Lower Merion Township permit search and official resources
Permit records in Pennsylvania sit with the authority that issued them — the municipality or its certified third-party agency, or the city department in Philadelphia and Pittsburgh. Where the Building and Planning Department is the authority for Lower Merion Township, it holds the building permit, the inspection history and the use-and-occupancy certificate. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — open permits and missing certificates are a common closing problem.
Confirm the authority having jurisdiction first. Pennsylvania enforces one statewide Uniform Construction Code, but each municipality administers it with its own amendments, fee schedule and enforcement route — local staff, a third-party agency, or opt-out — so the requirements that apply vary by parcel. Confirm current requirements, fees and review turnaround for your filing date.

Frequently asked questions
Why are there two historic bodies in Lower Merion?
They cover different property. The Historical Architectural Review Board, created in 1980 with nine members, reviews applications within the local historic districts. The Historical Commission, created in 2000 with seven members, reviews properties on the township’s Historic Resource Inventory that are not inside a local district.
What happens if I demolish a historic resource without approval?
The ordinance requires restoration. Anyone who demolishes a building, structure or site on the Historic Resource Inventory in violation of the chapter must restore it to its prior appearance, and in default the township may carry out the restoration and charge the cost, plus an administrative fee, as a municipal lien against the property. That is in addition to any other penalty.
Is my house on the Historic Resource Inventory?
It may be even if it is not in a designated district. A state-funded survey completed in 1991 identified more than eighty potential historic districts across the township, and the inventory reaches well beyond the formally designated ones. Confirm the status with the department before finalising a design.
What is the property resale certification?
A township requirement filed ahead of settlement. The certificate confirms that sidewalks and kerbs are in good condition, house numbers are visible from the street and smoke detectors are installed. It takes thirty to sixty days, and the fee is lower when the application is received twenty or more days before settlement.
Does the township recommend contractors?
No. The township declines to recommend contractors because of the conflict of interest and liability that would follow. It does keep resident feedback, positive or negative, on file and available for public review.
What contractor credential applies?
Pennsylvania has no statewide general-contractor licence. The township code carries its own contractor licensing chapter, and for residential home improvement the state registration with the Attorney General applies as well. Registration is administrative rather than a skills licence: there is no examination, the fee is one hundred dollars every two years, and new-home construction falls outside it. The online registration system returned to service in May 2026 after an outage, and the grace period that followed it closed on the eighth of June 2026, so a current registration number is the expectation now.
