You’ll need a construction permit to begin any project that involves constructing a new building or majorly renovating an existing structure.
Everyone from developers to owners to contractors should be familiar with the various types of building permits that might be required for their projects.
Read on to learn about each of the major types of construction permits and when you’ll need them.

What is a construction permit?
A construction permit is a document granted by a local government that gives permission to construct or alter a building. Without the proper construction permit, you cannot legally build or make certain renovations to a property.
Obtaining a construction permit entails submitting an application and getting it approved by your local government. This process can take anywhere from a couple of weeks to a few months, or even years in some cases. The appropriate department will assess your plans and grant you a construction permit if they’re deemed safe and compliant with local codes and laws.
Keep in mind that although this process can be tedious and time-consuming, there are construction permit services available to simplify and streamline it. For the best results, seek out permitting software that puts all your applications in one place and handles the tedious work for you.
When do you need a construction permit?
You’ll usually need a construction permit anytime a project involves building a new structure, changing the footprint of an existing building, altering structural components, or modifying major building systems like electrical, plumbing, or mechanical.
For existing structures, minor cosmetic updates — like painting, replacing flooring, installing cabinets, or similar finish work — don’t usually require a permit. But larger projects (like building an ADU, finishing a basement, removing load-bearing walls, adding square footage, or converting a space to a new use) commonly do.
Permits are generally required because local governments need to verify that the work meets current building codes, zoning rules, fire safety standards, and other applicable regulations.
Common projects that often require a construction permit include:
- New home or commercial building construction
- Room additions or expansions
- Major kitchen or bathroom remodels
- Decks, garages, and accessory structures
- HVAC, electrical, or plumbing upgrades
- Roof replacements in some jurisdictions
- Demolition or structural removal work
- Tenant improvements or change-of-use projects
Requirements vary significantly by city, county, and state. A project that needs a permit in one jurisdiction may not in another.
If you’re unsure, check with the local building department before starting work. Beginning construction without the proper permit can lead to stop-work orders, fines, delays, or complications when selling the property later.
6 main types of construction permits
There isn’t one universal list of construction permits used in every city. Permit names, categories, and approval paths vary by jurisdiction. However, most permits fall into a few major buckets that developers, contractors, and property owners should understand before starting a project.
At a high level, construction permits are usually organized by project type, building use, or scope of work.
The most common types of construction permits include:
- Commercial permits
- Multifamily permits
- Residential permits
- Trade permits
- Specialty permits
- Site development and civil permits
1. Commercial permits
Commercial construction refers to any property that is intended for commercial activity rather than residential purposes. This includes offices, retail stores, warehouses, restaurants, medical space, industrial facilities, and mixed-use commercial components.
A commercial construction permit is required when building, renovating, or adding to any commercial property.
You may need a commercial permit for:
- Ground-up commercial construction
- Interior tenant improvements
- Restaurant build-outs
- Office renovations
- Change-of-use projects
- Building additions or expansions
- Structural upgrades
Some jurisdictions separate commercial permits into categories such as shell permits, interior fit-outs, phased permits, or foundation-only permits.
New commercial developments
If you’re developing a brand-new commercial building, you’ll need a new commercial property permit. This type of permit is needed when the specific kind of business that will use the new building is known — i.e. when developing a grocery store, a bank, or some other known business.
Foundation only
If you’re only planning to lay the foundation of a commercial property, you can apply for a foundation-only permit.
Commercial remodeling
When you’re planning to make extensive interior or exterior changes to an existing commercial building, you’ll need a commercial remodeling permit.
2. Multifamily permits
Multifamily permits are typically required for residential buildings with multiple dwelling units. These projects often involve additional life safety, accessibility, and fire protection requirements.
Common multifamily projects include:
- Apartment developments
- Condominium buildings
- Townhome communities
- Student housing
- Senior housing communities
- Hotels and extended-stay lodging in some jurisdictions
Apartment and condo developments
An apartment building is any property with more than two dwelling units that are rented — not owned — by tenants. In contrast, a condo building has more than two dwelling units that generally are owned by the tenants.
If you plan to build either of these types of properties from scratch, you’ll need an apartment or condo construction permit.
Foundation only
Similarly to commercial construction, you may request a foundation-only permit for a multifamily property. This is ideal for situations where you’re still finalizing the construction plans but want to get a head start on the project.
Hotel and motels
Although a hotel is technically a commercial property because it generates income, hotels and motels are sometimes considered multifamily properties for permitting purposes because tenants reside in the dwelling units (even if just for a short time).
3. Residential permits
Residential building permits are required for any project that involves a single-family home or similar residential property without multiple dwelling units.
Typical residential permits include:
- New custom home construction
- Production home builds
- Home additions
- Basement finishing
- Garage conversions
- ADUs (Accessory Dwelling Units)
- Major remodels
- Structural repairs
- Pools, spas, and detached structures
Even projects that seem simple — like decks, retaining walls, or reroofing — may require a residential permit depending on local rules.
Custom home builds
A custom home is essentially a one-off home whose construction plans won’t be reused. If you’re developing a custom single-family home, this is the type of residential construction permit you’ll need.
Production home builds
While a custom home will only be built once, a production home is built according to master plans that are reused. As such, a production home build requires a slightly different permit than a custom home.
Foundation only
Once again, residential projects that don’t have approved plans can seek a foundation-only permit to get started.
Structure & interior demolition
If you plan to demolish an entire residential structure or a portion of a structure’s interior, you’ll need a demolition permit. The permit is needed to ensure that you’re safely demolishing and disposing of the materials.
Interior remodel
Any significant interior remodeling work requires this type of residential construction permit. If you’re not sure if your remodeling project requires a permit, be sure to check with your local building department.
Home daycare
While every state has its own laws and regulations regarding home daycare businesses, you’ll most likely need to obtain a permit if you plan to run a daycare out of your home.
The home daycare permit ensures that:
- There are proper fire safety measures in place
- Playgrounds and outdoor play areas are safe
- The home complies with building codes
4. Trade permits
A trade permit is any permit related to a specific component of the building. These trades require unique knowledge and procedures, so they require unique permits.
Mechanical permits
A mechanical permit applies to any mechanical work, including heating and cooling systems and ductwork.
You’ll need a mechanical permit in situations like:
- Installing an exhaust hood above a stove in a restaurant
- Replacing ductwork in an apartment building
- Installing a new heating system in an office building
Electrical permits
An electrical permit is needed when performing major electrical work on a building.
This could include:
- Wiring
- Transformers
- Lighting
Both residential and commercial properties often require electrical permits — though commercial properties may have more stringent requirements since their electrical needs are often more intensive.
Plumbing permit
You’ll need a plumbing permit when installing or upgrading plumbing systems in a new or existing structure.
Plumbing permits are often needed for projects that involve:
- Piping
- Sinks
- Toilets
- Drains
- Back-flow devices
5. Specialty permits
Many jurisdictions require specialty permits for work outside standard building scopes. These are often the permits teams overlook early in planning.
Examples include:
- Demolition permits for full or partial teardown work
- Sign permits for exterior building signage
- Roofing permits for roof replacement or structural roof work
- Solar permits for photovoltaic systems and battery storage
- Pool permits for in-ground pools, spas, and enclosures
- Elevator permits for new installations or modernization
- Fence permits in some cities or HOA-regulated areas
- Temporary structure permits for tents, trailers, or temporary buildings
- Generator permits for backup power systems
These permits often run on separate review timelines from the main project permit.
6. Site development and civil permits
Before vertical construction begins, many projects need approvals tied to land development and infrastructure.
These may include:
- Grading permits
- Excavation permits
- Utility connection permits
- Stormwater permits
- Right-of-way permits
- Driveway or curb cut permits
- Tree removal permits
- Erosion control permits
For ground-up commercial, multifamily, and subdivision projects, these permits can be just as critical as the building permit itself.
Why you should know about every construction permit type
Many projects require multiple permits at the same time, not just one. For example, a new restaurant may need a commercial building permit, electrical permit, plumbing permit, mechanical permit, fire suppression permit, sign permit, and health department approvals.
That’s why identifying permit requirements early is so important. Missing even one specialty permit can delay inspections, opening dates, or construction schedules.
Construction permit costs
Construction permit costs can range from under $100 for a simple trade permit to tens of thousands of dollars for large commercial or multifamily developments. There is no universal fee schedule because permit pricing is set at the local level and varies widely by jurisdiction.
In most cases, permit fees are based on one or more of the following:
- Project valuation: Estimated cost of construction
- Square footage: Size of the building or addition
- Project type: Residential, commercial, multifamily, trade work, demolition, etc.
- Scope complexity: Structural changes, life safety systems, phased construction, special reviews
- Number of permits required: Separate building, electrical, plumbing, mechanical, fire, and civil permits
- Plan review fees: Charges for reviewing submitted drawings and documents
- Inspection fees: Fees tied to required field inspections
Because of these variables, two similar-looking projects in different cities can have very different permit costs.
Typical permit cost ranges by type
The ranges below are general estimates. Actual fees depend on location and scope.
Which permits are usually more expensive?
Ground-up construction permits
New construction is typically the most expensive category because it often involves:
- Full plan review
- Multiple inspections
- Structural, fire, and accessibility review
- Utility and infrastructure coordination
- Impact or development-related fees in some jurisdictions
Large multifamily and commercial projects can generate substantial permitting costs because several agencies may review the same project.
Commercial vs. residential permits
Commercial permits often cost more than residential permits because commercial buildings usually have stricter code requirements related to occupancy, fire protection, ADA accessibility, and life safety systems.
A restaurant build-out, medical office, or industrial project may require additional departmental approvals that increase fees and timelines.
Trade permits
Trade permits are usually among the least expensive individual permits, but multiple trade permits on one project can add up quickly. For example, a remodel may require separate electrical, plumbing, and mechanical permits.
Best practices to pull construction permits faster
While approval timelines are controlled by the local jurisdiction, there are several ways to speed up the parts of the process you can control.
- Confirm permit requirements early
Identify every permit your project needs upfront, including trade or specialty permits that are easy to overlook. - Submit complete, accurate plans
Missing documents, inconsistent drawings, and incomplete applications are some of the most common causes of delays. - Use permit management software
Permit management software centralizes applications, tracks statuses, organizes documents, and reduces manual follow-up across projects. It can be especially valuable for teams managing multiple permits or jurisdictions at once. - Respond to corrections quickly
If the city requests revisions, fast and organized resubmittals can keep the review moving. - Coordinate permits in parallel when possible
Some projects can move faster when trade, civil, or specialty permits are planned alongside the main building permit. - Track status proactively
Don’t let applications sit unnoticed. Regular follow-up helps surface issues before they become schedule problems.
The fastest permit applications are usually the best-prepared ones. Clean submissions and proactive coordination typically matter more than anything else.
