Frequently Asked Questions

What is a building permit?
A building permit is official approval from your local jurisdiction (city or county building department) to construct, alter, or demolish a structure. It ensures the work will comply with building codes, zoning, and safety standards. Permit applications are reviewed for code compliance; approved work is then subject to inspections at specified stages (e.g. foundation, framing, rough MEP, final).
When is a building permit required?
Permits are typically required for new construction, additions, structural alterations, and often for major electrical, plumbing, mechanical (HVAC), and fire-suppression work. Minor repairs or cosmetic work may be exempt in some jurisdictions. Rules vary by locality—when in doubt, contact your building department. Doing work without a required permit can lead to fines, stop-work orders, and problems when selling or insuring the property.
How long does permit review take?
Review times vary by jurisdiction and project size. Simple over-the-counter permits (e.g. some electrical or plumbing) may be same-day; full plan check for new construction can take several weeks or months. Some departments offer expedited review for a fee. Our checklist helps you submit a complete package so the first review is not delayed for missing information.
What if I did work without a permit?
Many jurisdictions allow you to obtain a permit after the fact (retroactive or as-built permit). You may need to expose work for inspection, provide as-built drawings, and pay fees (sometimes with penalties). Unpermitted work can affect resale and insurance. Contact your building department to learn the process for legalizing existing work.

Checklist

Application

Applicant information: name, address, phone, email; owner if different from applicant
Required

Building department needs who is applying and who owns the property. If a contractor or agent is applying, owner authorization may be required. Have legal names and contact details ready.

Property

Property address and parcel or assessor number
Required

Exact address and parcel/APN so the permit is tied to the correct lot. Jurisdictions use this for zoning, fees, and inspection scheduling.

Project

Project description and use (e.g. single-family residence, commercial tenant improvement)
Required

Brief description of the work and building use. Determines which code and zoning rules apply and whether additional reviews (e.g. fire, health) are needed.

Scope: new construction, addition, alteration, repair; square footage and valuation
Required

Type of work and approximate square footage and construction value. Value is often used to calculate permit fees. Be consistent with contract or appraisal if applicable.

Plans

Site plan showing building location, setbacks, lot lines, utilities, and parking (if required)
Required

Required for most permits. Shows compliance with zoning setbacks and lot coverage. Some jurisdictions accept a simple site plan for small projects; larger or commercial projects may need a civil-engineered plan.

Floor plans: each level; room labels, dimensions, exits, and use
Required

Plans must match the scope of work. Show new and affected existing conditions. Include dimensions, exit paths, and room uses for code and occupancy review.

Exterior elevations and building sections (as required by jurisdiction and project type)

Often required for new construction and additions. Show height, materials, and relationship to grade. Large or commercial jobs may need full architectural set.

Structural drawings and calculations (if required); engineer stamp where applicable

Required when work is structural (foundations, framing, retaining walls, etc.). Must be signed and sealed by a licensed engineer in the state. Some jurisdictions require structural for certain alterations or remodels.

Mechanical, electrical, and plumbing (MEP) plans or details (as required)

Separate trade permits (electrical, plumbing, mechanical) may be needed, or MEP may be on the main permit. Follow local practice. Show equipment, loads, and code compliance.

Compliance

Architect and/or engineer stamps and signatures where required by law

Many jurisdictions require a licensed architect or engineer to stamp plans for commercial work, multi-family, or certain residential scope. Check state and local requirements.

Contractor license and insurance (if work will be performed by a licensed contractor)

Some jurisdictions require the contractor to be listed on the permit and to hold a valid license and insurance. Owner-builder permits may have different rules; check local requirements.

Other approvals if applicable: fire, health, environmental, historic, HOA

Certain projects need fire-department review, health approval, environmental or coastal clearance, or historic review. HOAs may have separate design approval. Identify and obtain before or as part of permit.

Zoning

Confirm zoning compliance: use, setbacks, height, lot coverage, and other zoning conditions
Required

Building department will check zoning. Verify use is allowed, setbacks are met, and no variances or conditional use permits are needed before you submit. Non-compliance will hold up or deny the permit.

Fees

Permit fees: plan check and/or permit fees; method of payment accepted
Required

Fees are usually based on valuation or square footage. Some departments collect plan-check fees at submittal and permit fees at issuance. Confirm amount and payment method (check, card, online).

Inspections

Understand required inspections (footing, foundation, framing, rough MEP, final, etc.)
Required

Permit will list when to call for inspection. Do not cover work before it is inspected. Schedule inspections per department process (phone, online, or app).
