Long Beach is built in layers, and the layers still show. Willmore City was subdivided in 1880 and renamed Long Beach, the city incorporated in 1897, and the Alamitos Land Company laid out Belmont Heights, Belmont Shore and Naples. The 1916 breakup of Rancho Los Cerritos produced Bixby Knolls, California Heights, Los Cerritos and North Long Beach. Then oil, the Douglas Aircraft plant and the Navy shipyard pushed the population from 55,593 in 1920 to 344,168 in 1960, and postwar tracts filled in the rest. The numbers behind that history: about 51.0 percent of the roughly 181,216 housing units predate 1960, 77.1 percent predate 1980, and the Housing Element counts 71 percent of homes as over 50 years old against 61 percent countywide. About 58.9 percent of households rent and 39.6 percent of units sit in buildings of five or more, so a landlord or an association often has a say beside the City. Old wiring, lead paint and original plumbing are why the kitchen remodeling, bathroom remodeling, painting and flooring installation pages begin with what is behind the surface.
Permits go through the Building and Safety Bureau's Permit Center, and two shortcuts matter. The Express Permit Service, bulletin IB-058, issues same-size window swaps, in-place kitchen and bath finishes and some shingle re-roofs with no plan review. The Over-the-Counter service, IB-002, can handle minor additions and decks at the desk. Neither is offered in the Coastal Zone, and Express is closed to historic districts too, so we check the address first. The 2025 state codes apply from January 1, 2026. A permit lasts two years but lapses if work has not started within 180 days, and standard plan review costs 85 percent of the permit fee, never less than $154, under the schedule effective October 1, 2026. The matching guides are window replacement, roofing and decks.
Several overlays can sit on one lot. Eighteen historic districts, from Belmont Heights to Wrigley, require a Certificate of Appropriateness for exterior changes such as re-roofing, windows, doors and paint, even where no building permit is needed, and the City charges nothing to review paint or a re-roof. The Coastal Zone requires a Local Coastal Development Permit or a categorical exclusion that can be appealed to the California Coastal Commission, and work waits for the 15 day appeal period. The methane zone, a legacy of the oil under the city, brings Chapter 18.79: additions below 50 percent of the existing area are exempt, and larger ones need soil gas testing and a recorded covenant. Hardscape of 5,000 square feet or more beside a mitigated building must be vented, which is why the concrete work page covers it. Planning also reviews every fence for location, height and material, with 3 feet allowed in a residential front yard. The fencing guide, the room addition guide and the ADU page explain how that plays out, including why Long Beach applies state ADU law directly while its own ordinance is in development.
Ground and weather finish the picture. State maps show liquefaction zones over parts of the city, including points checked in Belmont Shore, North Long Beach and Wrigley, and the 1933 earthquake, magnitude 6.4 with 120 deaths, did its worst damage to unreinforced masonry. Shoreline sites use Exposure D in the City's wind bulletin, rain averages 12.02 inches a year, and noise rules end work at 7 p.m. on weekdays. In the County's CAL FIRE layer every point we sampled came back Non-Wildland, though an address check on the state viewer is the real answer. MDG Builders, CSLB #1040337, is the general contractor that designs, permits and runs these jobs from Tarzana, with licensed subcontractors doing the trade work; our article on how general contractors use subcontractors explains the arrangement. Pasadena and Los Angeles show how other cities differ, and Lakewood, Seal Beach, Carson, Paramount and Bellflower run their own permit offices.

Hiring a general contractor in Long Beach: common questions
Where do I get a building permit in Long Beach?
At the Permit Center of the Building and Safety Bureau, listed on the second floor at 411 W. Ocean Boulevard, in person or by appointment. It is open Monday, Tuesday, Thursday and Friday 8:00 a.m. to 4:00 p.m. and Wednesday 9:00 a.m. to 4:00 p.m., closed noon to 1:00 p.m. Call 562.570.PMIT (7648) to confirm.
What is an Express Permit, and which jobs qualify?
An Express Permit is issued without plan review for listed simple jobs. Bulletin IB-058 covers same-size window replacement, in-place kitchen and bath finishes and fixtures with no layout change, and some composition shingle re-roofs. It is not available in a Coastal Zone or historic district, where the regular process applies.
How do I know if my Long Beach house is in a historic district or the Coastal Zone?
Ask the Permit Center to check the parcel before you design anything. The City lists 18 historic districts, and Historic Preservation answers questions at (562) 570-6194. Coastal Zone sites need a Local Coastal Development Permit or a categorical exclusion. We could not open the City's Coastal Zone map, so we do not name neighborhoods.
Does the methane zone affect a remodel or addition?
Mostly for additions. Chapter 18.79 exempts additions and changes of use below 50 percent of the existing structure area; larger ones need soil gas testing by a Qualified Professional, a recorded covenant and an annual sensor test. We could not confirm other remodel types, so ask the Permit Center about your address.
What hours can construction run in Long Beach?
Weekday and federal holiday work can run from 7:00 a.m. to 7:00 p.m., and Saturday work from 9:00 a.m. to 6:00 p.m. Sundays need a Sunday work permit from the Health Department's Noise Control Officer. Breaking the noise rule is a misdemeanor, with a fine capped at $500.
Is Long Beach in a wildfire hazard zone?
Not at the points we sampled. In the County's copy of CAL FIRE's local responsibility area layer, revised August 21, 2025, all 92 grid points that returned a zone came back Non-Wildland. That is a sample, not a parcel map, so check your address on the CAL FIRE viewer before ordering roofing, windows or decking.
How long is a Long Beach building permit valid, and what does plan review cost?
A permit is valid for two years from issuance and expires after 180 days if work has not started or has stopped for 180 days. Standard plan review is 85 percent of the building permit fee, with a minimum of $154, under fee documents effective October 1, 2026. Fees depend on job valuation, so ask the Permit Center for yours.
Who actually does the work if I hire MDG Builders in Long Beach?
Licensed specialty subcontractors do the field work. MDG Builders, CSLB #1040337, is the general contractor that writes the scope, prepares the permit drawings and keeps the trades on schedule. Each subcontractor's license number and certificate of insurance are available on request before the first day on site.
