Avoid These Common Hidden Costs in Renovations, Remodels, ADUs, and Custom Homes

Renovation and new construction are exciting endeavors. That said, knowing where unexpected costs can arise, will equip you to ensure your dream project stays on budget. Here are some common surprises and the professionals who can help you navigate them:

‍

Bad Soil Conditions - Geotechnical/Soils Engineers

Properties with weak or shifting soil may require complex foundation solutions, such as drilling piers. This can add tens of thousands to your budget. Get a geotechnical engineer’s report early to help identify these risks.

Fire Zone Requirements

If your property is in a designated fire zone, you may be required to install fire sprinklers or use fire-resistant materials, which can significantly increase costs.

Unanticipated Drainage Problems - Civil Engineers

If you’re excavating for a new foundation, you could discover poor drainage or water pooling, which may require installing drainage systems, costing thousands of dollars.

Hidden Issues Inside Walls

During demolition or remodeling, you might uncover dry rot, mold, or even asbestos. Addressing these can require specialized remediation, costing thousands of dollars.

Utility Upgrades

Adding significant square footage can trigger the need for utility upgrades like larger water, sewer, or electrical connections, leading to unplanned expenses and project delays.

Expensive Finish Selections - Architects and Interior Designers

Choosing premium countertops, fixtures, or cabinetry can quickly escalate costs. If you’re considering high-end finishes, allocate extra funds to cover these upgrades.

Tree Roots Interfering with Foundations - Arborists

Large trees near your build site can cause headaches if roots are found during excavation. Removing or working around roots can complicate foundation work or trigger local tree protection ordinances. Engage a consulting Arborist early to avoid surprises.

Landscaping, Decks, and Porches - Landscapers

Many homeowners decide to add landscaping, decks, or porches mid-project, which were not part of the initial budget. Planning for these elements early on can prevent surprises later.
