To find out if your neighbor has a building permit, search your city or county building department’s online permit portal by the property’s street address. Permits are public records, and anyone can look them up without giving a reason. If your jurisdiction doesn’t offer online access, or the portal is missing what you need, the same information is available at the building department counter or through a written public records request.
What to Have Ready Before You Search
The street address is usually enough. Two backup identifiers make the search faster when the address doesn’t return clean results.
The first is the Assessor’s Parcel Number, sometimes called a parcel identification number or tax parcel number. Every county tax assessor assigns one to each property, and it removes ambiguity when addresses are shared across units or have changed over time. You can pull it from your county tax assessor or property appraiser website, which almost always offers free online lookup by address.
The second is the owner’s name. Some portals let you search by owner, which helps when you’re unsure of the exact address format the system expects. The county assessor site that gave you the parcel number will usually list the owner as well.
Searching the Online Permit Portal
Search the web for your city or county name plus “building permit search” or “permit lookup.” The first .gov result is almost always the correct portal. Most cities and counties now offer some version of this, though depth and search quality vary.
Enter the street address on the portal. A small detail trips people up here: many systems want only the street number and street name, without the suffix. Try “123 Main” rather than “123 Main Street” or “123 Main St.” If that returns nothing, try the parcel number.
Results show every permit on file for the property. Each entry typically lists a permit number, a short description of the work, the issue date, and a current status. Click into a record for full details. Some jurisdictions split their databases by date, so if the search comes up empty, look for a separate archive or legacy records search covering older permits.
Online databases don’t always update in real time. A permit issued yesterday might not appear for several days or even weeks, depending on how often the jurisdiction refreshes its data. If you see active construction but the portal shows nothing, the lag might explain it. It’s also possible no permit was pulled.
Going In Person or Filing a Records Request
If the online portal is thin or missing, go to the building department in person. Bring the address, the owner’s name, and the parcel number. Staff can pull permit files and let you review them on site. Copies usually cost a small per-page fee, typically under a dollar.
You can also submit a formal public records request. Every state has its own open records law giving the public access to government documents, including building permits. These go by different names depending on where you live, such as “Public Records Act,” “Open Records Act,” or “Sunshine Law.” The federal Freedom of Information Act only applies to federal agencies, not local building departments, so the correct legal pathway is your state’s open records law.1FOIA.gov. Freedom of Information Act
Check the building department’s website for a records request form, or call and ask how they prefer to receive requests. Be specific about what you want, such as “all building permits issued for 456 Oak Lane in the last five years.” Response times and copying fees vary by jurisdiction, though most states require agencies to respond within five to ten business days.
Reading What the Permit Says
Finding the permit is half the job. Understanding it is the other half.
Scope of Work and Who Pulled It
The description of work spells out what construction the permit covers, in plain terms like “new roof,” “bathroom remodel,” or “200 sq ft deck addition.” That is the legal boundary of what’s authorized. If your neighbor appears to be building a second-story addition but the permit says “re-roof,” that gap is worth investigating.
The record also identifies who pulled the permit, usually the licensed contractor. You’ll see the contractor’s name and often a license number, along with the property owner’s name. Many permits list an estimated construction value reflecting the cost reported on the application.
Issue Date and Expiration
Every permit has an issue date, and most jurisdictions set an expiration window. The details vary, but it’s common for a permit to become void if work hasn’t started within six months to a year of issuance, or if work stops for a similar period. A permit issued two years ago with no inspection activity since has almost certainly expired, meaning the holder would need to renew or reapply before continuing.
Inspection History and Status
This is often the most revealing part of the record. Construction moves through inspections at key stages: foundation, framing, electrical rough-in, plumbing, and a final walkthrough. The record tracks each required inspection and whether it passed, failed, or is still pending.
The overall permit status tells you where the project stands. Common statuses include:
- Active: the permit has been paid for and work is underway
- Suspended: the permit has gone an extended period without a passed inspection
- Work stopped: the building department ordered construction to halt
- Finalized: all inspections passed and the project is complete and code-compliant
- Expired: the permit was never completed and is no longer valid
Finalized is what you want to see. It means the building department reviewed the finished work and confirmed it meets code. Anything else means the project is still in progress or has hit a problem.
When Nothing Shows Up
If the search returns nothing, there are a few possibilities. The simplest is that the work doesn’t require a permit. Cosmetic projects like painting, installing flooring, replacing cabinet hardware, or putting up playground equipment usually fall below the permit threshold, as do patios poured at grade without footings. Small repairs often don’t need permits either. The database might also have a lag, particularly for very recent permits.
Significant structural, electrical, or plumbing work with no permit on file is a different situation. Unpermitted construction can create problems beyond the neighbor’s own property. Shoddy electrical work is a fire risk. Improperly graded land can redirect drainage onto your lot. Structural changes done without engineering review can affect shared walls or boundary setbacks. And when unpermitted work surfaces during a home sale, it can complicate transactions and property values on the block.
The standard way to raise it is to contact your local building department. Most accept complaints by phone, through an online form, or through 311 if your city offers that service. You generally don’t need proof that the work is unpermitted; the department will send an inspector to check. Some jurisdictions accept anonymous complaints, but policies vary, and complete anonymity isn’t guaranteed because complaint records can become public once a case closes.
If an inspector confirms unpermitted work, the building department can issue a stop-work order requiring construction to halt immediately. The property owner typically has to apply for a permit retroactively, bring the work up to code, and pass the required inspections. In serious cases, the department can order portions of the work torn out and redone. Fines vary by locality and can add up quickly, especially if the owner ignores the stop-work order.
HOA Approval Is Not the Same as a Permit
If your neighborhood is governed by a homeowners association, there may be a second layer of approval beyond the building permit. Most HOAs require homeowners to submit an architectural review application before starting exterior modifications like additions, fences, or paint changes. These are separate from municipal building permits.
In most states, HOA members have a legal right to inspect official association records. To check whether your neighbor received HOA approval, submit a written request to the association’s management company or board. The governing documents usually spell out the process. HOA approval and a building permit are two different things: having one doesn’t mean the homeowner has the other, and both may be required.
