Remodeling in Huntington Beach

City planning guide · Local planning for Huntington Beach. Confirm the jurisdiction serving your address.

Contractor availability depends on your address, project and timing.

Most of Huntington Beach was built in two decades: close to two thirds of its homes date from the 1960s and 1970s. That history still shows up on a permit. Build near an old oil well and the fire department wants a methane barrier, and in Huntington Harbour or Sunset Beach the flood maps decide how high a new floor must sit.

What changes a remodel in Huntington Beach.

62.8 percent of Huntington Beach homes date from 1960 to 1979

The Census Bureau's 2020 to 2024 survey counts 82,624 housing units in Huntington Beach. Of those, 27,031 were built in the 1960s and 24,884 in the 1970s, and the median year built is 1974. Houses from that era were built before today's energy and electrical codes, so walls opened for a remodel can reveal original wiring, aging supply lines, single-pane windows and thin attic insulation. A kitchen or bath job in one of these tracts often turns into a wiring and plumbing job as well.

Building within 100 feet of an oil well means a methane barrier

In Huntington Beach, an old oil well near the lot is a building issue, not just a history lesson. The fire department's City Specification No. 429, updated in October 2025, requires methane mitigation for any building or enclosed structure within 100 feet of an active or abandoned oil or gas well. A single-family house under 5,000 square feet skips the soil gas testing because it automatically gets a methane barrier under the slab. The city's pre-approved ADU plan asks the same question, and a well on the lot or within 100 feet sends the plan for extra fire department approval.

Huntington Harbour and Sunset Beach sit in FEMA flood zones

FEMA's flood maps of March 21, 2019 placed properties in Huntington Harbour and Sunset Beach into AE or VE zones, the designations for areas with a 1 percent annual chance of flooding, VE adding wave action. In the city's floodplain, new construction or a substantial improvement worth 50 percent or more of the building's depreciated value must follow the floodplain overlay rules, which require residential buildings to be raised. Even small jobs lose their permit exemption there: the city's exempt-work list does not apply in the Floodplain Overlay District.

What a remodel costs in Huntington Beach in 2026.

$1,100,000

Median home valueOwner-occupied homes in Huntington Beach, Census ACS 2020-2024

Huntington Beach does not post permit valuations as open data, so the local figures come from the housing itself. The median owner-occupied home is valued at $1,100,000, and owners occupy 55.4 percent of the city's lived-in homes. ADUs have become a steady line of work: the city reported 87 ADU building permits to the state for 2025 and 132 for 2024.

For what jobs cost, the Census Bureau's 2023 American Housing Survey covers the wider Los Angeles-Long Beach-Anaheim metro. Owners there reported a median of $14,290 for roofing work, a number that mixes patch jobs with full tear-offs. Carpentry sets the pace on remodels, and the metro's median carpenter was paid $36.41 an hour in May 2025, against a $29.12 national figure.

Who issues permits in Huntington Beach.

The Building Division of the Huntington Beach Community Development Department issues building, electrical, plumbing, mechanical, pool and solar permits from the Permit Center at City Hall on Main Street. Applications and permit searches run through the HB ACA Portal, the city's Accela Citizen Access site. A permit stays valid for one year from issue, and fees are based on the project's valuation.

  • Painting, papering, tile, carpet, cabinets and countertops need no permit in Huntington Beach. Sheds, gazebos and playhouses up to 120 square feet and decks no higher than 30 inches off the ground need none either.
  • Masonry or concrete fences are exempt only up to 42 inches. Other fences are exempt up to 6 feet if they stay out of required zoning setbacks, and pool barriers always need a permit.
  • A reroof needs a permit unless it covers less than 100 square feet. A water heater, gas or electric, needs a permit even as a straight swap.
  • Replacement doors and windows are exempt when the waterproofing membrane is left alone and the egress opening stays the same size or larger.
  • None of the exemptions apply to work in the Floodplain Overlay District, an Environmentally Sensitive Area, or a project that needs a discretionary Planning Division approval.
  • ADUs and junior ADUs get ministerial review, meaning staff approve them against fixed standards without a hearing, but a project in the Coastal Zone may also need a Coastal Development Permit.
  • Huntington Beach hands out, at no charge, a pre-approved design for a one-story, 490 square foot detached ADU in California Ranch, Bungalow or Spanish Colonial style. The plan cannot be modified.
  • Huntington Beach has a certified Local Coastal Program. Its coastal zone covers eight specific plan areas, six of them certified; Brightwater and Sunset Beach are the two that are not.

What Huntington Beach homeowners plan most.

Roofing

Any reroof over 100 square feet needs a permit here. Our roofing guide was written for Los Angeles, where the same dry summers and winter rains wear roofs; Huntington Beach's Building Division issues the permit.

Kitchen remodel

In a 1960s or 1970s tract house, opening a kitchen wall often means new circuits and supply lines, and cabinets and counters alone need no permit.

Bathroom remodel

Tile and fixtures in the same spot are simple, but moving plumbing needs a permit. Our bathroom guide was written for Orange County; in Huntington Beach the permit comes from the city.

HVAC replacement

Adding central air to a house that never had it usually means new ducts, a bigger electrical service and a mechanical permit from the Building Division.

ADU or garage conversion

The city issued 87 ADU permits in 2025 and gives away a 490 square foot pre-approved plan. Check for an old oil well within 100 feet first.

Window replacement

Swapping single-pane aluminum windows is exempt only if the waterproofing membrane stays intact and the egress opening does not shrink.

Before you start.

How much does a roof replacement cost in Huntington Beach?

The city does not publish permit values, so the nearest benchmark is regional. Roofing jobs reported in the Census Bureau's 2023 housing survey for the metro that runs from Los Angeles through Orange County had a median of $14,290, with a margin of error of $4,090. Any reroof larger than 100 square feet in Huntington Beach needs a permit from the Building Division.

Do I need a permit to remodel in Huntington Beach?

For anything beyond finish work, yes. No permit is needed for painting, tile, carpet, cabinets or countertops, nor for sheds up to 120 square feet and decks up to 30 inches high. Water heaters and reroofs over 100 square feet need permits, and in the Floodplain Overlay District even the usual exemptions do not apply. Applications go through the HB ACA Portal.

What if there is an old oil well near my house in Huntington Beach?

Under the fire department's City Specification No. 429, any building or enclosed structure within 100 feet of an active or abandoned oil or gas well needs methane mitigation. A single-family home under 5,000 square feet gets a methane barrier under the slab instead of soil gas testing. An ADU near a well also needs extra fire department approval.

Is Huntington Harbour in a flood zone?

Yes. FEMA's maps of March 21, 2019 placed properties in Huntington Harbour and Sunset Beach into AE or VE flood zones. New construction there, or an improvement worth 50 percent or more of the building's depreciated value, must meet the city's floodplain overlay rules, which require homes to be raised. Owners who borrow from federally regulated lenders must carry flood insurance.

Does Huntington Beach have pre-approved ADU plans?

Yes. Huntington Beach hands out, at no charge, a pre-approved design for a one-story, 490 square foot detached ADU in three styles: California Ranch, Bungalow and Spanish Colonial. The plan cannot be changed. ADUs get ministerial review, meaning no public hearing, though a Coastal Zone lot can require a Coastal Development Permit as well. The city issued 87 ADU permits in 2025.
