Document Completed Conversion
Protect your investment by properly documenting your finished attic conversion, updating insurance coverage, and maintaining records for future home sales.
Why Documentation Protects Your Investment
Your attic conversion represents a significant investment of time and money. Proper documentation ensures you can prove the work was permitted and completed to code, which is essential for insurance coverage, future home sales, and property value assessments. When selling your home, buyers and their lenders will want proof that added living space was legally constructed. Without documentation, you may face difficulties closing sales or be forced to accept lower offers. Good records also help with warranty claims, future repairs, and insurance claims if damage occurs.

Step-by-Step Guide
Gather All Permits and Official Documents
Collect all official paperwork in one place:
- •Request copies of all inspection reports from building department
- •Obtain official certificate of occupancy or final approval
- •Keep original building permit with sign-offs
- •Retain copies of approved plans stamped by building department
- •Save any variance or zoning approvals
Take Professional-Quality Photos
Document the finished space thoroughly:
- •Photograph each room from multiple angles in good lighting
- •Capture views from windows, especially dormers
- •Document special features: built-ins, closets, architectural details
- •Photograph stairway from top and bottom
- •Take exterior shots showing dormers or roof changes
- •Consider hiring a professional photographer ($150-300) for listing-quality images
Pro Tip: Take photos in daylight with all lights on for best results. Clean and stage the space first. These photos are valuable for insurance claims and future sales.
Compile Contractor and Warranty Information
Organize all contractor documentation:
- •Create a list of all contractors with contact information
- •File copies of contracts showing scope of work
- •Organize warranties by trade (electrical, HVAC, roofing, etc.)
- •Note warranty expiration dates in your calendar
- •Keep product manuals for HVAC, fixtures, appliances
Update Homeowner's Insurance
Ensure your investment is properly protected:

Frequently Asked Questions
Why is documenting an attic conversion important?▼
Proper documentation protects your investment in several ways: it proves the work was permitted and inspected (crucial for home sales), supports insurance claims if damage occurs, helps with property tax assessments, provides warranty information for repairs, and demonstrates added square footage and value to potential buyers. Without documentation, you may face challenges proving the conversion is legal or claiming insurance coverage.
How much does an attic conversion add to home value?▼
A permitted, finished attic conversion typically adds 50-75% of its construction cost to home value. For example, a $50,000 conversion might add $25,000-$37,500 in value immediately. Long-term, the added square footage (often 200-500 sq ft) can increase home value by $15,000-$75,000 or more depending on your market's price per square foot. Bedrooms with proper egress windows add more value than bonus rooms.
Do I need to update my property taxes after an attic conversion?▼
In most jurisdictions, yes - the building department notifies the tax assessor when permits are finalized. Your property may be reassessed to reflect the added finished square footage. Tax increases vary but expect 10-20% higher property taxes if you've significantly increased living space. Some areas offer tax exemptions or phase-ins for home improvements. Check with your local assessor's office.
What documents should I keep from my attic conversion?▼
Keep: original building permits, all inspection reports, certificate of occupancy, approved architectural plans, contractor contracts and warranties, receipts for major materials, HVAC system documentation, electrical panel diagram updates, photos of work in progress and completed, paint colors and material specifications. Store digitally and in hard copy. These will be invaluable for insurance claims, future repairs, or home sales.
