- Skipping Permit Research
Bethesda has strict zoning and building regulations. Not understanding permit requirements can delay your project or lead to costly fines. - Ignoring Setback Rules
Many Bethesda neighborhoods have setback and height limits. Failing to follow these can result in rejected plans or forced redesigns. - Underestimating Costs
Home additions in Bethesda are expensive due to labor, materials, and permitting. Always build in a 15–20% buffer for unexpected costs. - Hiring Unlicensed Contractors
Some homeowners hire cheap, unlicensed crews. In Montgomery County, this can void permits or lead to legal trouble. - No Detailed Design Plan
Jumping into construction without architectural drawings or a layout plan causes confusion, change orders, and delays. - Not Checking HOA Rules
Many Bethesda communities have HOAs that require separate design approval before county permits can be issued. - Choosing Aesthetics Over Function
Design should match your home’s style and layout. Poor design choices can lower your resale value instead of increasing it. - Overlooking Utility Upgrades
Additions may require electrical panel upgrades, plumbing extensions, or HVAC changes—often missed during initial planning. - Skipping a Soil or Structural Review
Some Bethesda lots have poor soil conditions or sloped terrain. A structural engineer should evaluate feasibility first. - Not Getting a Written Contract
Verbal agreements or vague contracts often lead to disputes. Always protect yourself with a detailed written agreement.
