Royal Oak, Michigan Building Permit Guide

Royal Oak is a built-up inner-ring city in Oakland County, where much of the building work is renovation, replacement and infill on established lots. 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.

What requires a building permit in Royal Oak?

The code is the same statewide, but fee schedules, procedures 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.

Local rules worth knowing

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.

Michigan enforces one statewide construction code under the Stille-DeRossett-Hale Single State Construction Code Act (1972 PA 230); local units cannot amend it, and enforcement sits with the city, village or township, a county program or the state Bureau of Construction Codes, sometimes split by trade. Michigan rules

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.

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.

The two permits use different online systems. Engineering permits are applied for on BSAonline.com under the Royal Oak municipality, after the registration form and certificate of insurance have gone to the Engineering Division (engineering@romi.gov). Building permits, fee payments and inspection requests now run through accessmygov.com; the Building Department issues the PIN that links an account to the City of Royal Oak (248-246-3210).

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. Many lots in the older neighbourhoods are small, so the zoning position — setbacks and lot coverage — should be confirmed before drawings are commissioned rather than after.

How Michigan contractor credentials work

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 plans reviewed by a state-registered plan reviewer; detached one- and two-family houses of 3,500 square feet or less need no architect or engineer seal. Confirm what the Royal Oak Building Division requires for the specific building before filing.

Michigan licenses residential builders and maintenance and alteration contractors at state level, and the permit application must carry the licence number. Michigan rules

Royal Oak permit costs and fees

Royal Oak’s residential building permit fee is $12 per $1,000 of estimated construction cost, with the cost computed from the ICC square-foot construction cost table and a $100 minimum, plus a plan review fee paid before review starts ($450 for a new home; $100 to $425 for additions by size; $40 for most alterations). Trade permits are charged separately, and the engineering permit has its own schedule, which the Engineering Division updates every year.

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.

Fees are set by the enforcing agency — the local unit, a county program or the state — and may only fund that agency's work. Michigan rules

Trade permits and who may pull them

Electrical, plumbing and mechanical contractors hold state licences valid anywhere in Michigan, and each trade follows its part of the state construction code. Michigan rules

How to apply for a Royal Oak building permit

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 trade parts and the building parts moved on different dates, and houses still follow the 2015 residential code, so 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.

A Michigan permit lapses if work does not start within 180 days or stops for 180 days; confirm the expiry with Royal Oak on phased or delayed work. Michigan rules

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.

Ask the enforcing agency which edition applies to your application, especially around a code change date — because editions are adopted part by part, the answer can differ between the building inspection and the trade inspections on the same job. They are carried out by an inspector registered with the state, 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.

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. The contractor must apply: the city does not accept engineering permit applications from homeowners, and commercial liability insurance is required.

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 plumbing, mechanical and electrical parts to new editions on the twelfth of March, 2024, and the building and rehabilitation parts to their 2021 editions on the ninth of April, 2025; houses still follow the 2015 Michigan Residential Code. The residential code did not move with them. Replacement residential rules were filed for an August 2025 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 2015 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 (engineering@romi.gov), then apply for the engineering permit on BSAonline.com 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.
