Building a house is exciting—but navigating municipal permits, fees, and review steps can be confusing and costly if you’re unprepared. This guide explains the common permit types, how fees are calculated, the typical review workflow, red flags that cause delays or fines, and practical steps to keep your project on schedule and on budget.
Quick overview: why permits and reviews matter
- Permits ensure your home meets safety, energy, and zoning rules.
- Plan review verifies designs before construction; inspections confirm work is built to code.
- Fees fund municipal review staff and inspections—expect them at multiple stages.
- Missing permits or failed inspections can lead to costly rework, fines, or stop-work orders.

Common permit types and how fees are calculated
Municipalities charge a variety of permits and associated fees. Understanding each helps avoid surprises.
- Building permit (primary): Charged by valuation or square footage. Typically the largest single fee.
- Plan review fee: Paid on submittal; some municipalities apply it to the final permit fee, others do not.
- Mechanical / Electrical / Plumbing (MEP) permits: Separate trade permits for qualified work.
- Grading and erosion control permits: For earthwork and stormwater management.
- Impact or development fees: Charged for added burden on local services (roads, schools, parks).
- Sewer/water connection fees: For new connections or capacity increases.
- Inspection fees / re-inspection fees: Additional costs if failed inspections require extra visits.
- Variance / special permit fees: If you need relief from zoning rules.
- Permit extension or amendment fees: For changes or schedule overruns.
How fees are typically calculated
- Based on project valuation, square footage, number of fixtures, or flat rate for specific permits.
- Plan review often a percentage of the building permit fee or a separate flat fee.
- Impact fees calculated per unit/bedroom or by valuation depending on jurisdiction.
- Municipal fee schedules are published—always check local fee tables early.

Typical review steps and timelines
Understanding the municipal workflow helps you anticipate holds and plan for cash flow.
H3: 1. Pre-application / intake
- Optional but valuable: meet staff to identify issues early (zoning, setbacks, stormwater).
- Bring site plan, conceptual drawings, and questions.
- Benefit: can reduce formal review cycles.
H3: 2. Formal plan submittal & plan review
- Submit complete plans, energy compliance forms, structural calculations, and any application forms.
- Plan reviewers (zoning, building, fire, public works) comment on required changes.
- Expect at least one round of comments; multiple resubmittals extend time.
H3: 3. Permit issuance
- After satisfactory plan review and payment of fees, permit is issued.
- Do not start work before issuance—unauthorized work risks fines and stop-work orders.
H3: 4. Inspections during construction
- Typical inspections: footing, foundation, framing, MEP roughs, insulation, drywall (where required), final.
- Schedule inspections in advance; many jurisdictions allow online booking.
- Failed inspections trigger re-inspection fees and delays.
H3: 5. Final inspection & certificate of occupancy (CO)
- Final inspection verifies compliance with approved plans and codes.
- Once passed, municipality issues a CO or final approval allowing occupancy.

Red flags that cause delays, higher fees or fines
- Incomplete or inconsistent plans (missing details, mismatched sheets).
- Unpermitted work started before permit issuance.
- Failed inspections due to poor workmanship or non-compliant materials.
- Code changes enacted during review that affect your design.
- Easements, covenants, or HOA restrictions that conflict with approvals. See What to look out for when building a house: HOA rules, covenants and local restrictions.
- Need for variances (setbacks, height) that require public hearings. See What to look out for when building a house: when you need variances and how to get them.
- Unlicensed contractors or unclear contractor responsibilities—exposing you to legal liabilities. See Legal liabilities and contractor responsibilities: what to look out for when building a house.
- Underestimating impact fees or utility connection charges.

How to reduce fees and speed up reviews
- Meet planning staff early (pre-application) to identify obstacles.
- Submit complete, coordinated plans with all required forms and calculations.
- Hire experienced local designers/engineers who know municipal expectations.
- Use a permit expeditor if your project is complex or time-sensitive.
- Request combined or staged permits if the jurisdiction allows (e.g., foundation-only permits).
- Track inspection scheduling and avoid repeated failures by doing internal quality checks.
- Document all approvals and changes—helps avoid disputes and rework.
