TL;DR: What To Do If You Bought a House With Unpermitted Work
If you bought a home and later discovered unpermitted work, start by gathering information before making assumptions. Search available San Diego permit history, review your home inspection report, compare the current home layout to official records, and document what looks altered.
Unpermitted work does not automatically mean the home is unsafe, but it can affect resale, insurance, future remodeling, and permit approval. Work involving structure, plumbing, electrical systems, additions, garage conversions, or ADUs deserves careful evaluation.
Before you call the city without preparation, consider having a qualified contractor assess the visible work, identify likely concerns, and help you understand whether plans, engineering, selective demolition, or corrections may be needed for a retro-active building permit.
The goal is to understand the scope first, then decide the next step.
Finding out that your home may have unpermitted work after you already bought it can feel incredibly frustrating.
You may feel blindsided. You may wonder whether the seller should have told you. You may worry that your insurance, resale value, or future remodel plans are now at risk. You may also be wondering whether you inherited a problem that is going to become expensive before you even understand what it is.
If that is where you are right now, take a breath.
This situation is more common than many homeowners realize, especially in older San Diego homes where bathrooms, kitchens, garage conversions, electrical upgrades, patio enclosures, room additions, and ADUs may have been modified over several decades. Sometimes the work was done by a prior owner. Sometimes records are incomplete. Sometimes a project was started with good intentions but never fully closed out.
The first step is not panic. The first step is finding out what was permitted, what may not have been permitted, and what risk that creates for your home.
The City of San Diego allows homeowners and professionals to request or search prior permit records, plans, land use records, and related property information through Development Services records. Those records can help determine whether prior work was legally constructed and completed, though the city notes that not all older records may be available because record procedures and requirements have changed over time.
In this guide, we will walk through what to do after discovering possible unpermitted work, how to gather records, when to involve a contractor, and how to begin building a responsible plan.
This article is not legal advice. It is practical remodeling and permitting guidance from our perspective as a San Diego general contractor helping homeowners evaluate what may need to happen next.

What should we do if we bought a house with unpermitted work
If you bought a house with unpermitted work, the first thing we recommend is slowing down long enough to gather facts.
It is natural to want a quick answer. You want to know whether the work is legal, whether it is safe, whether you can sell the home later, and how much it might cost to fix. But unpermitted work is not one single type of problem. It can range from a minor record issue to a major structural, electrical, plumbing, or occupancy concern.
Start by identifying what part of the home is in question. Is it a bathroom that does not appear in records? A garage conversion? A wall removal? An addition? A second kitchen? An ADU? An electrical panel upgrade? Each of those situations has a different path.
Next, gather your documents. Review your home inspection report, seller disclosures, appraisal documents, listing photos, title paperwork, and any renovation invoices or plans you were given during the purchase. Sometimes evidence of prior work appears in documents even if permit records are unclear.
Then compare the home as it exists today to available public records. In San Diego, permit records can help verify prior permits, drawings, and related property files, though older records may not always be complete. If your home is in unincorporated San Diego County rather than the City of San Diego, the county also provides online public records tools for permit history, fees, inspections, and building permit activity.
Once you have a basic understanding of the suspected issue, the next step is a professional evaluation. This is where a San Diego general contractor familiar with unpermitted remodels can help. We can walk the home, review visible conditions, identify what systems may be involved, and help you understand whether the concern appears cosmetic, structural, mechanical, or code-related.
For example, a bathroom added without permits may involve plumbing, ventilation, electrical, waterproofing, and layout questions. A wall removed without permits may require structural evaluation. A garage conversion may raise questions about fire separation, insulation, windows, ceiling height, and whether the space can legally be used as living area.
We do not recommend assuming every unpermitted improvement must be demolished. We also do not recommend ignoring it. The practical path sits between those extremes: gather records, evaluate the work, understand the risks, then decide whether documentation, correction, retroactive permitting, or remodeling makes the most sense.
When you call us early, our goal is to help you understand what you are dealing with before you spend money in the wrong direction.
Are we responsible for unpermitted work from a previous owner
This is one of the most frustrating parts of discovering unpermitted work after purchase.
Many homeowners feel like they are being asked to solve a problem they did not create. That feeling is understandable. But from a practical ownership standpoint, once you own the home, the property condition becomes your responsibility to manage.
That does not mean you caused the issue. It means you may need to address it if it affects safety, resale, insurance, future remodeling, or city compliance.
The question of whether a seller, agent, inspector, or prior contractor has responsibility is a legal question, and you should speak with a qualified real estate attorney if you believe material facts were not disclosed. From our side as a remodeling and construction team, our role is different. We help you understand what exists in the home and what may need to happen to bring it into a safer, more compliant condition.
Some unpermitted work remains undiscovered for years because no one checks permit history closely until a trigger event occurs. That trigger may be a remodel, a refinance, a home sale, an appraisal, an insurance inspection, or a neighbor complaint. Once the issue comes to light, it becomes difficult to ignore.
If you are planning a remodel, unpermitted work can also complicate new permit applications. For example, if you want to remodel a kitchen but the existing footprint includes an unpermitted addition, the city may require that condition to be resolved before approving new work. If you want to build an ADU but prior unpermitted structures affect setbacks or lot coverage, the earlier issue may influence your new project.
This is why we encourage homeowners to address unpermitted work strategically rather than emotionally. The goal is to determine whether the prior work is safe, whether it can remain, whether it can be legalized, and whether correcting it can be paired with improvements you already want to make.
You may not have created the problem. But with the right plan, you can often control how you move forward.
Can unpermitted work affect insurance or resale
Yes, unpermitted work can affect both insurance and resale, especially when the work involves structure, electrical systems, plumbing, additions, converted spaces, or separate living areas.
From a resale perspective, buyers often become concerned when they discover that parts of a home may not have been permitted. Their concern is not only about paperwork. They worry about safety, future liability, lender issues, insurance coverage, and whether they will inherit correction costs after closing.
Permit history can also come up during inspections, appraisals, disclosures, and buyer due diligence. If a room addition, bathroom, garage conversion, or ADU does not appear in records, buyers may renegotiate or request that the issue be resolved before closing.
From an insurance standpoint, unpermitted work can create additional concerns. Some insurance carriers may limit or deny coverage for damage connected to unpermitted improvements, especially if the work contributed to the claim. For example, if unpermitted electrical work causes a fire, or unpermitted plumbing causes water damage, the insurer may review whether the work was approved and completed properly. Real estate and mortgage resources also warn that insurers may limit or deny coverage tied to unpermitted work.
This does not mean every unpermitted issue will automatically block a sale or void insurance. It means the risk should be understood and addressed before it becomes urgent.
If you plan to sell eventually, legalizing unpermitted work before listing may reduce buyer hesitation and improve confidence. If you plan to stay, addressing unpermitted work can protect your future remodeling plans and reduce surprises later.
We approach this from a practical standpoint. We help homeowners identify what type of work is in question, whether safety concerns are visible, whether documentation may exist, and what correction path may be reasonable. From there, you can make a better decision about whether to legalize, repair, remodel, or phase the work.
Should we call the city before calling a contractor
Sometimes yes, but not always as the first step.
If you have already received a code violation notice, official letter, citation, or inspection request, you should not ignore it. In those cases, city deadlines may apply, and you may need to respond promptly. A contractor can still help you prepare, but official communication should be taken seriously.
If you have not received a notice and you simply suspect unpermitted work, it is often wise to begin with a contractor evaluation first. That does not mean hiding anything. It means understanding what you have before you begin a city process you are not prepared to navigate.
When homeowners call the city with only partial information, they may not know how to describe the work accurately. They may say “garage conversion” when the issue is actually a storage room, office, or unpermitted dwelling unit. They may say “wall removal” without knowing whether it was structural. They may say “addition” without knowing whether it affects setbacks, lot coverage, or habitable space.
A local contractor evaluation can help organize the facts. We can identify what appears altered, what trades may be involved, whether engineering may be needed, and what documents you should gather. That way, when you do speak with the city, architect, engineer, or permit consultant, you are not starting from confusion.
The City of San Diego provides access to permit records and historical permit data through its records resources and online permit tools. Reviewing that information before making assumptions can be an important first step.
Our recommendation is simple: if there is an active notice, respond responsibly. If there is no notice yet, evaluate first, gather records, and then decide the right path.
How do we find out what work was permitted
To find out what work was permitted, start with permit records.
For properties in the City of San Diego, the Development Services Department maintains building permits, plans, maps, and related land development records. The city’s records bulletin explains that this information can help property buyers and owners verify whether a project required approval and was legally constructed and completed.
You can search or request records using the property address, parcel information, contractor license information, or record details when available. The city’s online systems and records resources may provide permit activity, inspection history, and historical data.
If your home is outside city limits and located in unincorporated San Diego County, you will need to use county resources rather than City of San Diego records. The county’s Planning and Development Services public records tools allow property owners to research permit history and related building permit information online.
After reviewing records, compare them to the current home. Does the permit history show the bathroom that exists today? Does the square footage match? Does the garage appear as a garage, or has it been converted? Was an electrical panel upgrade finaled? Were structural changes inspected?
Keep in mind that older permit records may be incomplete, especially for homes with long histories. Lack of a record does not always tell the full story, but it raises questions that should be investigated.
A contractor can help compare visible conditions to available records and identify where the home may not align. If needed, drawings, engineering, or additional professional documentation may be required to move forward.
