Start with the age and the occupancy of the building, because both are unusual here. Wikipedia says John P. Jones and Robert Baker founded the town in 1875 and that it incorporated on November 30, 1886, with the Pier opening in 1909. Its census table shows the population rising from 15,252 in 1920 to 37,146 in 1930 and 71,595 in 1950, a surge that Wikipedia ties partly to Douglas Aircraft, which built a plant at Clover Field in 1922 and employed as many as 44,000 people in 1943. Wikipedia's neighborhood page adds that Sunset Park is mostly small one-story houses from the 1940s built for those workers. The Census Bureau's ACS 2024 one-year tables count 54,322 housing units: 14.9 percent date from 1939 or earlier and 71.7 percent from before 1980. Only 20.7 percent are detached houses, 63.7 percent sit in buildings of five or more units, and 74.6 percent of the 49,229 households rent. So a kitchen remodel, a bathroom remodel or new flooring is often work on a 1940s bungalow or inside a rented unit, where SMMC 8.100.080 makes the owner responsible for having mold or asbestos handled by certified experts.
Permits run through the Building and Safety Division's Permit Services Center, and the process is paperless: applications go into the Electronic Plan Review system before anyone visits the counter, which is open 8:00 a.m. to 3:00 p.m. Monday through Thursday. Submittals are evaluated under the 2025 California Standards Code effective January 1, 2026. The City sorts residential work into Same-Day, Minor, Medium and Single-Family tracks, with initial reviews listed as same day, 5 days, 3 weeks and 4 weeks, and it warns that plan review is currently running past those estimates. A licensed contractor pulling a permit needs a current City business license, proof of the contractor license and proof of workers' compensation insurance. Permit applications generally expire a year after a complete submittal, and jobs of $50,000 or more, or 1,000 square feet or more, need a waste management plan and deposit. The City's page gives no fee amounts, so we print none; ask for the current schedule. Work hours are fixed by SMMC 4.12.110: weekdays until 6:00 p.m., Saturday from 9:00 a.m. to 5:00 p.m. and never on Sundays.
Three overlays decide how long a job takes. The first is the coast. The City says its Coastal Zone takes in much of Downtown, including the Third Street Promenade, and because Santa Monica has no certified Implementation Plan the California Coastal Commission, not the City, still decides coastal permits; a June 2026 agreement aims at a certified program by the end of 2027. SMMC 8.08.070 holds a building permit until a needed coastal permit exists. We did not find the Coastal Zone boundary map or a list of exempt work, so we make no claim about any address until the City confirms it. The second is preservation. Five historic districts, Third Street Neighborhood, Bay Street Craftsman Cluster, San Vicente Boulevard Courtyard Apartments, 11th Street Bungalow and 4th Street Corner, sit beside a landmark list numbered through 143. Ordinary maintenance such as a like-for-like roof or side and rear yard fence is approved administratively, while the Third Street district also reviews windows, front fences and a paint color change. The third is a demolition test: SMMC 9.25.030 counts removal of more than 50 percent of exterior wall elements over five years, which can pull a large room addition into a 75-day Landmarks window on an older house.
Tenants, lots and weather finish the picture. Rent control has applied since April 10, 1979 to most rental buildings built before that date, and SMMC 8.100 can require an approved construction means and method plan before a permit when the work could affect habitability. On the lot, R1 zoning caps fences, walls and hedges in the front setback at 42 inches and front paving at 50 percent of the required setback area, while side and rear fences and walls may reach 8 feet. The City's sources disagree on which fence height needs a permit, 4 and 7 feet in the code versus 6 feet on its permit pages, so confirm the line before ordering materials. For ADU construction, SMMC 9.31.025 approves compliant units without a hearing, and the concrete and deck pages cover the paving and 30 inch rules. NOAA's 1991 to 2020 normals give 13.45 inches of rain a year, 82 percent of it December through March, so exterior work fits the long dry stretch. MDG Builders is the general contractor of record under CSLB #1040337: we scope the job, handle plan check, schedule licensed specialty subcontractors and walk the result with you, and you may ask for each subcontractor's license and certificate of insurance. Our article on subcontractors explains the arrangement, and the nearest hub with a finished page is Los Angeles.

Santa Monica project questions we answer most
Who issues coastal permits in Santa Monica?
The California Coastal Commission, not the City, currently holds coastal permitting. The City has no certified Implementation Plan for its Local Coastal Program and aims to certify one by the end of 2027. We could not find the boundary map, so confirm with the City whether your address is covered.
Where do I apply for a building permit in Santa Monica, and how long does review take?
Apply online through the Permit Services Center's Electronic Plan Review system. The City lists Same-Day, 5-day, 3-week and 4-week initial reviews depending on scope, and says plan review is currently running past those estimates. We do not print fees because the page we read gives none. Ask the Building and Safety Division for current timing.
How do I know whether my Santa Monica house is a landmark or in a historic district?
Check the City's Historic Districts list and its landmark list, then ask the Landmarks Commission staff about your parcel. Five districts exist, and the landmark list is numbered through 143. Contributing buildings and landmarks need a certificate of appropriateness for most exterior changes, while ordinary maintenance is approved administratively under SMMC 9.56.210.
Does a remodel in a Santa Monica rental building need a tenant plan?
Often yes. SMMC 8.100 requires anyone altering a building with dwelling units to say whether tenants live there. If the work could affect habitability, an approved construction means and method plan is required before the permit, and tenants may receive written notice. Rent control has applied since April 10, 1979 to most rental buildings built before that date.
When does a Santa Monica remodel or addition count as a demolition?
SMMC 9.25.030 counts a project as a demolition when more than 50 percent of exterior wall elements are removed or stop being structural over five years. On Historic Resources Inventory buildings over 40 years old, the thresholds drop to 25 percent of street-facing walls or 50 percent of all walls. Older buildings then face a 75-day Landmarks window.
How tall can a fence be on a Santa Monica lot?
Fences, walls and hedges in a front setback are limited to 42 inches, and side and rear fences and walls may reach 8 feet under SMMC 9.21.050. The permit height is unclear: the municipal code says 4 feet for masonry and 7 for other fences, while the City's permit pages say 6 feet. Confirm before buying materials.
What hours can contractors work in Santa Monica?
Weekday work may run from 8 a.m. to 6 p.m., Saturday work from 9 a.m. to 5 p.m., and SMMC 4.12.110 bars Sundays and eight listed holidays. Each permitted site must post a bilingual English and Spanish sign showing the hours, the City's violation phone numbers and the permit number.
Can I build an ADU on my Santa Monica lot?
Usually yes. SMMC 9.31.025 approves an ADU that meets its standards without a hearing, and the City must act on a complete application within 60 days for a parcel with an existing home. On a single-unit parcel the City allows one converted ADU, one JADU and two more ADUs. Coastal Zone or historic lots can add review time.
