How to Apply for a Building Permit: A Homeowner Step-by-Step

Applying for a building permit now usually means opening an account on your city’s online portal, and each city calls it something different.

You already know you need a permit.

The harder part is figuring out how to apply without spending half a Saturday guessing which form belongs to which counter. This walkthrough is the sequence most homeowners actually follow—find the right department, describe the work clearly, get drawings that match what you told them, and then stay ahead of inspections. It is not a national checklist. Your city or county still writes the rules.

If you are still unsure whether the project needs a permit at all, start with our plain-English overview: Do I Need a Building Permit? Once you know you need one, come back here.

Step 1: Find the department that actually issues the permit

Search “[your city] building permit” or “[your county] planning and development.” Skip the first result if it is a contractor lead-gen site. You want a .gov page with office hours, an address, and a phone number for the permit counter.

Big cities often split the work. New York’s Department of Buildings lays out when owners need permits on its own site (NYC DOB: Do I Need a Permit?). Los Angeles publishes a construction-process overview through LADBS (LADBS permit application information). Boise has a homeowners’ guide that walks through the local process (City of Boise homeowners’ guide). Use those as models for what a clear local page looks like—not as rules for your address.

Call before you drive. Ask: “I’m a homeowner planning [brief project]. Which permit types do I need, and do I apply online or in person?” Write down the person’s name. That note saves you when you get a different answer later.

Step 2: Write a scope of work a stranger can understand

The application asks what you are doing. Vague answers create delays. Compare these two:

• Bad: “Bathroom remodel.”
• Better: “Replace existing bathtub with walk-in shower in same location; new GFCI receptacles; new exhaust fan vented to exterior; no wall relocation; no change to plumbing stack.”

Include rooms, what stays, what moves, and whether you are touching structure, plumbing, gas, or electrical. If you are hiring a licensed contractor, ask them to draft the scopethen read it yourself before it goes on the form. You are still the property owner of record on most applications.

Some jurisdictions want a separate electrical or plumbing permit even when the building permit covers the framing. Ask that question early so you do not learn it at the counter with a line behind you.

Step 3: Gather drawings that match the scope

For small like-for-like work, a simple floor plan with dimensions may be enough. For additions, decks attached to the house, or anything that changes load paths, expect more: foundation details, framing plans, elevations, and sometimes engineered drawings.

Model residential codes published through the International Code Council are a common baseline many cities adopt and amend (ICC residential codes). Your city may use an older edition or local amendments. Do not buy a code book and assume it matches your permit desk.

Practical tip: label every drawing with your address, a sheet number, and the date. If you revise after a plan review comment, bump the revision date. Reviewers hate guessing which set is current.

Step 4: Online portal vs. the counter

Many offices push homeowners to an online portal. Create the account with an email you check. Upload PDFs that are actually readable on a tablet—no phone photos of pencil sketches if you can help it. Name files clearly: 123-Main-floor-plan-revA.pdf beats scan0047.pdf.

Other places still want you in person for the first visit, especially if zoning clearance or historic review is involved. Bring photo ID, proof you own the property (tax bill or deed info), and payment. Some counters only take cards; some only take checks. Ask when you call.

Chicago publishes a homeowner guide to permits that shows how a large city explains the process to non-professionals (City of Chicago Guide to Permits (PDF)). Again: illustrative. Your packet will differ.

For real examples of different front doors, see how Kansas City routes applications through CompassKC, how Nashville takes homeowner applications by email, and how Baltimore files permits in E-Permits.

Step 5: Fees are local—do not trust a blog “average”

Permit fees are set by ordinance. They may be flat, valuation-based, or a mix. Square footage, valuation of work, and whether trade permits piggyback all change the total. We will not invent a national average here because it would be wrong for almost everyone who reads it.

Ask the counter for a fee estimate once they have your scope. Ask what happens if the valuation changes after plan review. Ask whether inspection fees are bundled or separate. Get the answers in writing if the portal shows a fee schedulescreenshot it.

Financing can add paperwork too. HUD’s Single Family 203(k) materials show how some FHA rehab loans interact with construction documentation (HUD 203(k) overview)—they do not replace your building department’s rules.

Step 6: Plan review comments are normal, not a failure

Reviewers send comments. Respond to each one. If they ask for a detail you do not understand, call and ask them to point to the code section or local amendment. Fix the drawings; do not argue in the portal comments thread unless you have a clear technical basis.

Common triggers for extra rounds:

• Drawings that do not match the written scope
• Missing dimensions on stairs, landings, or guardrails
• Energy or egress notes left blank on additions
• Contractor license or insurance fields incomplete
• Zoning setbacks or lot coverage never checked

Anne Arundel County’s “Do I Need a Permit?” page is a good example of how some counties try to answer the threshold question before you even apply (Anne Arundel County: Do I Need a Permit?). Use your own county’s equivalent page the same way.

Step 7: After issuance—inspections and the job card

When the permit issues, read the inspection list. Rough-in inspections usually come before finishes. Final comes last. Do not cover work that still needs eyes. If your electrician finishes early, schedule the electrical rough before the drywall goes up. That one habit prevents tear-outs.

Keep the permit packet on site—inspectors often want the approved plans handy. Photograph the posted card; they blow away. If work pauses for months, ask how expiration and extensions work locally. Do not assume a one-year clock. Once the permit is issued, our permit expiration calculator shows when it could lapse if work or inspections stall.

Common delays (and how homeowners usually cause them)

1. Starting work before issuance. A stop-work order is expensive and embarrassing. Wait for the signed permit.
2. Changing the design midstream. Moving a wall after approval often means a revision. Call before you move it.
3. Hiring an unlicensed trade where licensing is required. The department may refuse inspections.
4. Ignoring HOA or historic district rules. The city permit does not override private covenants or landmark boards.
5. Floodplain or coastal overlays. Extra elevation or floodproofing paperwork can apply. FEMA’s homeowner FAQ packet is a starting point for flood-related questions—not a substitute for your floodplain administrator (FEMA homeowner FAQ (PDF)).

A simple timeline mindset (not a promise)

Think in stages: research call, submittal, plan review, issuance, rough inspections, final. Ask the counter for their current review-queue estimate when you submit, write it down, and check the portal weekly instead of hourly.

Before you hit submit

Read your application once more. Confirm the address, the owner name, and the scope. Confirm you linked the right contractor, if any. Confirm payment went through. Then save a PDF of everything you uploaded.

Next time you are at the counter, bring the scope, the drawings, and one clear question. That is usually enough to get a useful answer instead of a shrug.

FAQ

Can I apply for a building permit online?

In most large cities, yes. Salt Lake City, Seattle, Denver, Philadelphia, Portland, Tampa, and New York City all take applications through online portals.

Where can I look up old permits for my house?

Often in the same portal. Salt Lake City’s Citizen Access Portal has public permit records from 1979 to the present.
