Royal Oak is one of the densest and most active redevelopment markets in Oakland County, with older neighbourhoods where setback and lot-coverage enforcement is strict. Two things trip up people who have not worked here: a permit most cities fold into the building permit, and a name that belongs to two separate governments.
Building Inspection issues permits for commercial and residential construction and performs the related electrical, structural and plumbing inspections, with Ordinance Enforcement handling property maintenance, merchant licensing and public health and safety alongside it.
This guide covers the City of Royal Oak. Royal Oak Township is a separate unit of government with its own building department and its own procedures, and the two are frequently confused.
City of Royal Oak and Royal Oak Township are different governments. Royal Oak Township runs its own building department, taking building, inspection and sign permits for residential and commercial property, and its applications are submitted to its own township hall rather than to the city. Confirm which of the two holds your parcel before preparing anything, because nothing transfers between them.
What requires a building permit in Royal Oak?
Michigan builds on a single statewide construction code adopted under the Stille-DeRossett-Hale Single State Construction Code Act (1972 PA 230) and administered by the Bureau of Construction Codes within the Department of Licensing and Regulatory Affairs. The state code adopts International Code Council model codes with Michigan amendments, but it adopts them part by part on separate effective dates — the building and rehabilitation parts, the plumbing part, the mechanical part and the electrical part each move on their own schedule. Local units may amend only to make the code more restrictive, never less, and local amendments are filed with the bureau. So the first question in Royal Oak is which authority holds the code for the parcel and which edition governs each part of the work.
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 electrical part of the state code and the referenced National Electrical Code
- Plumbing and gas work under the plumbing part of the state code, pulled by a state-licensed plumber
- 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 Royal Oak Building Division before work starts.
The statewide layers that apply everywhere
Two Michigan features catch projects owners assume are simple. First, enforcement runs down a three-tier ladder: the local unit of government administers and enforces the act and the code; where it declines to, the county may give notice that it will; and where neither does, the bureau’s director assumes responsibility for that unit. Unlike states where the county never issues a building permit, a Michigan county can be the authority having jurisdiction outright. Second, licensing is statewide, not local: residential builders and maintenance and alteration contractors are licensed by the state, as are the plumbing, electrical and mechanical trades, and the permit application itself must carry the licence number and its expiry date. The residential part in particular has not moved in step with the commercial parts, so a house and a shop on the same street can be reviewed against editions years apart — confirm the edition in force for each part on your filing date. Great Lakes and inland floodplain administration applies along the state’s shorelines and rivers, and snow loading is a live structural constraint. Royal Oak also separates out the right of way. Builders and contractors doing major renovations or new construction homes are required to hold an engineering permit covering any damage to the public right of way, underground water and sewer lead installations, sidewalk and approach replacement, and lawn restoration — a permit obtained through the Engineering Division on a registration form with a certificate of insurance.
Who handles permitting in Royal Oak?
Building Inspection issues permits for commercial and residential construction and performs electrical, structural and plumbing inspections, enforcing local ordinance as it applies to those functions.
| Detail | Information |
|---|---|
| Department | City of Royal Oak Building Division |
| Address | 203 South Troy Street, Royal Oak, MI 48067 |
| Phone | (248) 246-3210 |
| Hours | Monday to Thursday, 8:00 a.m. to 4:30 p.m.; Friday to noon |
| Engineering permit | Separate permit through the Engineering Division for right-of-way work |
| Engineering registration | Registration form and certificate of insurance sent to Engineering |
| Dumpsters and pods | Engineering permit required for placement in the roadway or right of way |
| Separate authority | Royal Oak Township permits its own territory |
The engineering permit catches more situations than its name suggests. It is required when a dumpster, storage pod or other container needs to be placed in the roadway, a parking spot or the public right of way; when electrical services are installed underground instead of aerially; and when a commercial or multi-family property repairs, resurfaces or replaces its car park. On a dense city site, at least one of those usually applies.
Access runs through the city’s online system. The engineering registration form and a certificate of insurance go to the Engineering Division first, and the permit is then applied for through the portal under the Royal Oak municipality. Building permits and rental property records are searchable through the same system.
Permit types
Residential permits
Residential permits cover structural, electrical, plumbing and mechanical work, with cosmetic work, minor repairs and replacement in kind generally outside the requirement. Setback and lot-coverage enforcement is strict in the older neighbourhoods, so the zoning position on a tight lot should be confirmed before drawings are commissioned rather than after.
How Michigan contractor credentials work
Michigan does license at state level, and the licence is the substantive credential rather than a registration. Residential builders and maintenance and alteration contractors are licensed under Article 24 of Public Act 299 of 1980, administered by the Bureau of Construction Codes, and the plumbing, electrical and mechanical trades are licensed by the state as well. A state licence is valid across the whole of Michigan; what does not travel is the local permit, fee schedule and inspection route.
The licence number goes on the permit application. Michigan requires the application to set out the licence number and expiry date of the residential builder, maintenance and alteration contractor, architect or engineer acting for the owner, together with a written instrument — a contract, power of attorney or letter of authorisation — showing that person is authorised to act. Doing residential work that requires a licence without one is a civil violation, which the county prosecuting attorney or the Attorney General may pursue. Confirm what the Royal Oak Building Division requires for the parcel, along with insurance coverage.
Commercial permits
Commercial and multi-family work runs through plan review with sealed drawings, and the engineering permit category for major commercial and multi-family developments applies separately. Car park repair, resurfacing or replacement on a commercial or multi-family property needs its own engineering permit whether or not any building work accompanies it.
Licenses, trade classifications and design professionals
Practically, three credential layers appear on Michigan projects: the state residential builder or maintenance and alteration licence on residential work; separately licensed electrical, plumbing and mechanical trades, also licensed by the state; and, on commercial and larger residential work, drawings sealed by a Michigan-licensed architect or professional engineer, with a licensed plan reviewer required on commercial work above defined thresholds. Confirm what the Royal Oak Building Division requires for the specific building before filing.
Royal Oak permit costs and fees
Royal Oak fees follow the published schedule by permit type and project value, with the engineering permit charged separately from the building permit and re-inspection fees where an inspection fails.
| Fee component | How it works |
|---|---|
| Building permit | Based on project valuation or square footage; set by the local unit, the county, or the state where it is the authority |
| Plan review | A percentage of the permit fee or a flat charge; commercial work above defined thresholds needs a licensed plan reviewer |
| Trade permits | Separate electrical, plumbing and mechanical fees under the local schedule |
| State construction code fee | The statutory state fee collected with the permit under the construction code act |
| 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 |
Michigan fees are set by whoever holds enforcement for the parcel — the local unit, the county, or the state where neither has taken it on — so the schedule follows the authority rather than the state. A figure from a neighbouring municipality is not reliable, and a figure from a neighbouring township can be wrong even where the county enforces both. Ask the Royal Oak Building Division 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 own part of the state construction code, and is tied to a contractor holding the relevant state licence — which, unlike a municipal credential, is portable across the whole of Michigan.
Michigan licenses the trades at state level. Electrical, plumbing and mechanical contractors hold licences issued by the state, valid anywhere in Michigan, and residential builders and maintenance and alteration contractors are licensed the same way. What varies by parcel is not the licence but the permit, the fee and the inspection route. Performing residential work that requires a licence without holding one is a civil violation the county prosecutor or the Attorney General may act on.
- Electrical work follows the electrical part of the state code and the referenced National Electrical Code, under a state-licensed electrical contractor.
- Plumbing work follows the plumbing part of the state code, under a state-licensed master or journeyman plumber.
- Mechanical work follows the mechanical and energy parts of the state code, under a state-licensed mechanical contractor.
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 Royal Oak building permit
The City of Royal Oak and Royal Oak Township are separate governments with separate building departments. Settle this from the parcel first.
Send the completed registration form and certificate of insurance to the Engineering Division before applying for the engineering permit.
Right-of-way damage, underground water and sewer leads, sidewalk and approach replacement, lawn restoration, dumpsters and pods in the roadway, underground electrical services and car park works.
Setback and lot-coverage enforcement is strict in the older neighbourhoods, so check before drawings are commissioned.
Apply through the city online system, confirming the code edition in force for each part of the work.
The counter runs Monday to Thursday to half past four and closes at noon on Friday, so plan any in-person step accordingly.
Review, corrections and what actually causes delay
In Michigan, the first cause of delay is uncertainty over who enforces the code — filing with the local unit when the county holds enforcement for it, or with the county when the state does. After that comes the edition question, because the building, plumbing, mechanical and electrical parts moved on different dates and a submission drawn to the wrong one is a correction cycle. Then a missing or expired state licence number on the application, energy-code and plan documentation, and floodplain requirements along the shorelines and rivers. Build the plan-review time into the schedule and confirm the checklist with the Royal Oak Building Division before filing.
Approvals do not stay live indefinitely. A Michigan 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 Royal Oak
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. Where an engineering permit applies, the right-of-way restoration is signed off separately from the building inspections, so the job is not closed until both are.
Michigan inspections are keyed to the code edition in force when the permit issued — which, because editions are adopted part by part, can differ between the building inspection and the trade inspections on the same job. They are carried out by an inspector certified by the bureau, employed or contracted by whichever authority holds enforcement for the parcel. Keep the approved plans and the energy-code documentation on site for the inspector to check against, and confirm the notice the Royal Oak Building Division 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.
Royal Oak permit search and official resources
Permit records in Michigan sit with the authority that issued them — the local unit, the county, or the state bureau where neither took enforcement on. Where the Royal Oak Building Division is the authority for the City of Royal Oak, 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, then confirm the edition. Michigan enforces one statewide construction code, but enforcement may sit with the local unit, the county or the state, and the code is adopted part by part on separate effective dates. Both questions have to be answered for the parcel and the filing date before the requirements are knowable.

Frequently asked questions
Is Royal Oak Township part of the City of Royal Oak?
No. Royal Oak Township is a separate unit of government with its own building department, responsible for building permits, inspections and sign permits for residential and commercial property in its own territory. Applications go to its township hall, not to the city, and nothing transfers between the two.
What is the engineering permit and do I need one?
It is a separate permit from the Engineering Division. Builders and contractors doing major renovations or new construction homes are required to hold one to cover damage to the public right of way, underground water and sewer lead installations, sidewalk and approach replacement, and lawn restoration.
When else does an engineering permit apply?
When a dumpster, storage pod or other container is placed in the roadway, a parking spot or the public right of way; when electrical services are installed underground rather than aerially; and when a commercial or multi-family property repairs, resurfaces or replaces its car park.
Which code edition applies to my work?
It depends which part of the code the work falls under. One Michigan point catches almost everyone: the commercial and residential codes are not on the same edition. The bureau moved the building and rehabilitation parts to their two thousand twenty-one editions on the ninth of April, two thousand twenty-five, and the plumbing, mechanical and electrical parts moved on their own two thousand twenty-four dates. The residential code did not move with them. Replacement residential rules were filed for an August two thousand twenty-five effective date, but the Court of Claims entered a stipulated order stopping the department from implementing them while a builders’ association challenge is litigated, so the bureau still lists the two thousand fifteen Michigan Residential Code as the code in force. That case was still live when this guide was written. Confirm the edition governing each part of your work on your filing date rather than assuming the newest one applies.
How do I get set up for the engineering permit?
Send the completed registration form and a certificate of insurance to the Engineering Division, then apply for the engineering permit through the city online system under the Royal Oak municipality.
Do I need a licensed contractor?
For work requiring a licence, yes, and the licence is issued by the state rather than the city. Residential builders and maintenance and alteration contractors are licensed by the state under Article 24 of Public Act 299 of 1980, administered by the Bureau of Construction Codes, and the plumbing, electrical and mechanical trades are state-licensed as well. The licence is valid statewide. The permit application must set out the licence number and its expiry date, and performing residential work that requires a licence without holding one is a civil violation the county prosecuting attorney or the Attorney General may pursue.
