Permits · Plan check · Inspections

Build it right. Build it legal.

A building permit isn’t just paperwork. It means a city inspector has checked that the work is safe and built to code — and it protects you when you insure, refinance or sell your home.

Why it matters

What a permit protects

Most construction in California — additions, ADUs, structural changes, new electrical, plumbing and mechanical work, and many remodels — requires a permit from your city or county.

01

Your family’s safety

Inspectors check foundations, framing, wiring, plumbing, gas lines and fire safety at key stages — before walls are closed up and problems are hidden.

02

Your home’s value

Permitted space counts. Unpermitted additions or ADUs can lower appraisals and may not be counted as legal living space.

03

Selling without trouble

Sellers are expected to disclose known unpermitted work. Buyers, inspectors and lenders often find it — and it can delay or cancel a sale.

04

Insurance coverage

If damage is traced to unpermitted work, an insurance claim may be questioned or denied.

05

Avoiding fines and rework

Cities can issue stop-work orders and penalties, and may require walls to be opened or work removed so it can be inspected.

06

Rental income for ADUs

A permitted ADU can be legally rented. An unpermitted one can bring code-enforcement problems instead of income.

Common permits

What your project may need

The exact permits depend on your project and your city. We find out what’s required and handle it for you.

Building
New homes, additions, ADUs, structural changes and most remodels.
Planning & zoning
Confirms setbacks, height and lot rules — often reviewed before the building permit.
Electrical
New circuits, panel upgrades, EV chargers and rewiring.
Plumbing
New fixtures, moved drains, water heaters, gas lines and sewer work.
Mechanical
Heating, air conditioning, ducts and ventilation.
Demolition & grading
Removing structures, moving soil and controlling drainage on the site.

Some properties also need other approvals — for example coastal development review near the coast, or HOA approval. We’ll tell you up front what applies to your property.

How we do it

We handle the permit process

Permits can take weeks or months and several rounds of corrections. We manage it from start to finish so you don’t have to deal with the city yourself.

  1. STEP 01

    Check requirements

    We find out which permits and approvals your project and property need.

  2. STEP 02

    Prepare the plans

    Architectural and structural drawings prepared to the city’s requirements. Why design matters →

  3. STEP 03

    Submit to the city

    We submit the plans, forms and documents and pay attention to every detail.

  4. STEP 04

    Plan-check corrections

    We respond to the city’s comments and resubmit until the plans are approved.

  5. STEP 05

    Permit issued

    We pull the permit — construction can start legally.

  6. STEP 06

    Inspections & final

    We schedule and pass every inspection through final sign-off, so your project is fully closed out.
