Hard money lender requirements for unpermitted additions

Hard money lenders view unpermitted additions as a risk because they can affect property value, legality, and future salability. Typically, a lender will require a clear plan to bring the addition to code or factor its removal into the loan's scope and budget.

Understanding the lender's concern

Unpermitted additions represent a significant risk to a hard money lender. These additions might not meet local building codes, could be structurally unsound, or might not be insurable. This means the property's actual value, and thus the lender's collateral, is uncertain.

A lender's primary concern is protecting its investment. If a property has unpermitted work, it can complicate the appraisal, delay future sales, or even require costly demolition and rebuilding, all of which reduce the safety margin for the loan.

Assessing the extent of the unpermitted work

The first thing a lender will want to know is the scope of the unpermitted work. Is it a small patio enclosure, or a full second story addition? The larger and more integral the unpermitted structure, the higher the risk and the more scrutiny it will receive.

You will need to be transparent about any unpermitted work you discover during your due diligence. Attempting to conceal it will only lead to bigger problems if it is found during appraisal or inspection.

Cost and plan for remediation or legalization

Hard money lenders are primarily interested in your plan to address the unpermitted addition. This usually means either bringing it up to code with proper permits or, in some cases, demolishing it and restoring the property to its permitted state. You will need a detailed budget for this.

Present a clear scope of work that includes the estimated costs for obtaining permits, any necessary structural changes, and professional inspections. This demonstrates to the lender that you have a viable strategy to mitigate the associated risks.

Impact on After Repair Value (ARV)

The unpermitted addition's effect on the After Repair Value (ARV) is crucial. If the addition cannot be permitted, it may not be included in the appraised value of the property, potentially lowering your ARV and reducing the maximum loan amount a lender is willing to offer.

Ensure your ARV calculations are conservative when dealing with unpermitted work. Factor in the costs and potential delays of legalization or removal, and understand that the 'value' of unpermitted square footage might be zero to an appraiser until it's compliant.

Documentation and disclosures to the lender

Be prepared to provide all available documentation related to the property, even if it highlights the unpermitted nature of the work. This includes original plans, previous sales documents, and any communications with the city or county building department.

Full disclosure upfront builds trust with your lender. Hiding information will likely lead to delays or outright denial once the issue is discovered through their own due diligence processes, such as appraisal or title search.

The role of appraisal and inspection

The hard money lender will rely heavily on the appraisal and a property inspection to assess the property's true value and the risks associated with the unpermitted addition. The appraiser will note any unpermitted areas and may exclude them from the square footage used for valuation until they are legalized.

A professional inspector can identify structural problems or code violations related to the addition. Be prepared for the lender to require that these items are specifically addressed and budgeted for in your rehab plan as a condition for funding.

Questions people ask

Will a lender always deny a loan for an unpermitted addition?

Not always. Many hard money lenders will consider the loan if you have a clear plan and budget to bring the addition up to code or remove it, as long as the numbers still make sense for the deal.

Do I need to get permits before applying for the loan?

You typically do not need to have the permits in hand, but you will need to demonstrate a clear understanding of the permitting process, estimated costs, and a timeline for obtaining them as part of your rehab plan.

How does an unpermitted addition affect the appraisal?

An appraiser will likely note the unpermitted status and may not include the unpermitted square footage in the property's total living area for valuation purposes until it is brought up to code, potentially lowering the appraised value.
