What zoning and permits rules require from building, fire, health and land-use reviewers?

Permission is granted against documents. Not against a conversation, not against what the last occupier did, and not against the landlord's description of the building. This page lists what the offices actually ask you to produce, in the order they ask for it, so you can assemble it before a deadline rather than during one.

The rules themselves are local. What is portable is the shape of the request, and knowing that shape lets you ask a precise question of the office that answers it.

What to take away

Every office wants the same three things firstthe address, an honest description of the activity, and a drawing that shows what you propose.
Describe the process rather than the industry. Use tables are written around activities, and your industry label may not appear in one.
Ask each office what it needs in writing, and keep the reply from the body that decides.

The information every application starts from

Assemble this once. Almost every office will ask for some of it.

Application Starter Information

Exact address and parcel identifier
Last approved use and date
Activity, hours, people, vehicles, deliveries
Area occupied and position in building
Layout, entrances, exits, parking drawing
Responsible person and contact details

The six items are:

The full address, including the unit or suite.
A description of the activity, written as what happens on the floor.
A site plan showing the building, parking, access and any outdoor area you will use.
A floor plan to scale, with the rooms, walls and equipment you are adding or moving.
The lease or other written authorization from the owner to apply.
Any prior approvals for the space, with their dates and reference numbers.

Write the activity description honestly and once, then reuse it. Different descriptions of the same business given to different offices is the fastest way to a problem you cannot fix later.

What the land use office asks for

This is the question of whether your activity is allowed at that address at all. The general legal machinery, and why it is decided locally, is summarized in the entry on zoning.

Land Use Office Submittals

District the parcel sits in
Activity in use-table terms
Permitted outright, conditional, or absent
Performance standardsnoise, hours, lighting
Parking and loading calculations
Whether prior lawful use has lapsed

If the previous occupier's activity is not the same as yours, nothing about their approval transfers. If the building has been vacant a long time, ask specifically whether a previously lawful use has lapsed. The concept behind that question is nonconforming use, and the answer decides whether you inherit anything at all.

In most US cities the land use application is a site plan review or a conditional use permit. Canadian cities commonly call the same step a development permit, and Ontario adds a zoning certificate or, where the site does not quite comply, a minor variance.

What the building department asks for

Drawings stamped by whoever local rules require to stamp them.
The code editions the jurisdiction has adopted, which the department itself will tell you.
A description of what is being altered, because the threshold between a minor alteration and a full upgrade is what decides your budget.
The occupant load you are proposing, which drives exits, restrooms and sometimes sprinklers.
Confirmation of what the space was approved as, from the department's own records.

In most US states the adopted code is a version of the International Building Code. In Canada it is the National Building Code of Canada or a provincial code such as the Ontario Building Code.

What the fire authority asks for

What you store and in what quantity, described by material rather than by product name.
Exit routes, travel distances and door hardware.
Whether the fire protection in place suits what you are bringing in.
Any process involving heat, flame, dust or compressed gas.

Ask the fire official directly rather than through the landlord, because the view of your building is specific to your building.

What other bodies may ask for

Not every application meets these, but each one that applies adds time.

Health.Anything involving food preparation brings a separate inspection regime with its own plan review.
Environmental.Discharges to drain, air emissions, waste handling, and runoff from a yard or a parking area. Where a site drains to a storm system, the federal framework behind the local rule is the NPDES stormwater program.
Transport.Access, turning, sight lines and, above a threshold of vehicle movements, sometimes an assessment.
Signage.Frequently a separate consent with its own drawings.
Historic or design review.Adds a committee, and committees meet on a calendar.
Utilities.Any excavation on or near the site brings a locating process into play, described at call before you dig.

The documents you produce, by stage

Stage	Office	What you hand over
Before you make an offer	Land use	Address, activity description, district question
Before the lease is signed	Land use and fire	Written confirmations, conditions attached
Before design	Building	Adopted code editions, records of prior approval
At application	Building	The building permit application, stamped drawings, occupant load, materials list
At application	Fire	Storage and quantities by material, exit routes, door hardware
At application	Health	Plan review application, menu or process list, sink and drainage layout
At application	Environmental	Discharge points, waste handling, yard and parking drainage
At application	Transport	Access and turning plan, sight lines, vehicle movement count
During review	All	Written responses to comments, revised drawings
During construction	Building, fire	Booked inspections at defined stages
Before occupation	Building	Final sign-off, certificate of occupancy, then the landlord's own list

Getting confirmations that are worth having

A confirmation is only useful if it names the address, the activity and the date, and comes from the office that decides. Describe the activity in full, including the parts you would rather not mention, because a confirmation obtained on a partial description protects nobody.

Make the deal depend on the answers. The way to structure that, and what to do when an answer arrives conditional, is in zoning and permits. The clauses that carry the risk if the answer is wrong belong in the lease, and those are in commercial leasing.

Where the requirements get heaviest

Food and drink, because health and licensing sit on top of everything else. Food service brings a health plan review and a licence on top of the building permit, each with its own drawings. The sequence is in hospitality property.
Anything with a yard, outdoor storage or night movements, which is where industrial districts most often say no. Conditions usually attach to screening, hours and access. The operational side is in industrial space.
A change of activity in a trading unit, where signage, shopfront and access consents arrive together. They are three separate applications to three different offices, each with its own drawings. That order is set out in retail space.

Common questions

Can the landlord give me the answer?

The landlord can tell you what they believe. Only the office that issues the approval can tell you what will happen, and only when it has your description in front of it.

How long does all this take?

Nobody can tell you from a page. Ask the office for its published fee schedule and current review times, which most departments post in a permit portal. As a typical range, a simple tenant improvement in an approved use runs a few weeks to a few months. A change of use with a public hearing runs longer.

What if my activity is not in the use table?

Absent is not the same as prohibited, and it is not the same as permitted. Ask how the office classifies activities that are not listed, because there is usually a procedure, and it takes longer.

Do I need a professional for this?

For a simple change of occupier in a space already approved for the same activity, often not. For a change of use, an unusual process, or a building with history, the cost of the wrong answer is much larger than the cost of advice.
