The houses Mission Hills is made of
Mission Hills was subdivided in 1908 and connected to downtown by streetcar in 1910. Most of the older houses date from that subdivision through the 1930s: Craftsman bungalows, Prairie-influenced houses, Mission and Spanish Colonial Revival homes, with a smaller group of 1950s Modernist houses.
A house from this period is older than 45 years, was almost certainly painted with lead paint before 1978, and was built with lath and plaster, a raised wood-framed floor, early wiring and galvanized pipe. Each shows up in the permit path, the safety rules or the budget.
The 45-year review: what triggers it and what is exempt
The City of San Diego requires a Potential Historical Resource Review before it issues a construction permit for any parcel that holds a structure 45 years old or older (San Diego Municipal Code section 143.0212, explained in Information Bulletin 580). Staff review plans, photos of every elevation and the County building record. The City says it typically takes ten business days for ministerial projects and twenty for discretionary ones.
Two exemptions matter for remodels. Interior development is exempt, and so are modifications limited to an electrical, plumbing or mechanical permit, as long as there is no change to the exterior. An interior kitchen or bath remodel on an undesignated home does not trigger it; a new window, moved door, addition or roofline change does.
If staff decide the house is not historic, the parcel is exempt from further historical review for five years. If it is potentially historic, exterior changes are checked against the Secretary of the Interior's Standards; a project that meets them proceeds, one that does not is redesigned or goes to a historical research report and possibly a Historical Resources Board hearing. The City offers a free half-hour meeting with Historical Resources staff; take it before drawings are final.
Designated homes and the three historic districts
Mission Hills has two locally designated districts and one National Register district. The Mission Hills Historic District was approved by the Historical Resources Board in July 2007 with 75 homes around Sunset Boulevard, Sheridan Avenue and Lyndon Road; a 2014 extension added 99 homes. The Fort Stockton Line Historic District, approved the same month, follows the 1913 streetcar line along Fort Stockton Drive, West Lewis and Pine Street with 107 homes. Inspiration Heights, south of Sunset Boulevard, was listed on the National Register in December 2021.
A home that is individually designated, sits inside an adopted district, or is listed on or eligible for the National or California Register falls under Information Bulletin 581 instead. The City reviews every alteration to such a property for consistency with the Standards, in its words even those alterations that would normally not require a permit. Review is billed hourly on top of permit fees, and a project that fails the Standards goes to a discretionary process with a public hearing.
What is protected is the character-defining fabric. National Park Service guidance treats floor plans, primary rooms, wood floors, plaster, trim, stairs and original finishes as features to retain, and calls bathrooms and kitchens secondary spaces that may accept greater change without compromising historic character. A new kitchen in a designated Craftsman is usually workable; removing a built-in buffet or replacing original windows is where review gets serious.
The Mills Act in plain terms
The Mills Act is a State program the City has run since 1995. The owner of a locally designated home signs a ten-year agreement to maintain it to the Standards and carry out a ten-year rehabilitation plan; in return the County Assessor values the property under a State formula that usually lowers the tax bill. The City says savings have ranged from 20 to 70 percent and vary by property; owners who have held a home since before Proposition 13 may see little benefit. The agreement renews automatically each year and runs with the property.
Timing matters. Local designation comes first; a National Register listing alone does not qualify. The property must have been designated by December 31 of the prior year, and the application must be in by March 31. City fees, updated July 1, 2025, are $3,444.36 for the designation nomination and $1,334.24 for the Mills Act application, plus a monitoring fee every five years. The work plan needs contractor cost estimates.
Lead paint and asbestos: the rules that apply to the work itself
Federal law presumes lead-based paint in any home built before 1978. Under the EPA Renovation, Repair and Painting rule, anyone paid to disturb painted surfaces in such a home must work for an EPA- or state-certified firm, under a certified renovator, using lead-safe practices. The small-job exemption is 6 square feet of painted surface per interior room or 20 square feet outside; a remodel is far past that. The firm must also give the owner EPA's lead hazard pamphlet before work.
The practices are specific: the work area is sealed so dust does not leave it, open-flame burning of paint is prohibited, heat guns above 1,100 degrees Fahrenheit are prohibited, and power sanding or grinding of painted surfaces is allowed only with a shroud and a HEPA vacuum attached. A certified renovator does a visual inspection and wipe test before barriers come down. Ask any contractor for their EPA RRP firm certificate before they touch a painted surface in a pre-1978 house.
- ◆Asbestos is the other pre-1980 material: nine-by-nine floor tile, the black mastic under it, some plaster and textured coatings, duct wrap and pipe insulation.
- ◆EPA's guidance: you cannot tell by looking, undisturbed material in good condition is generally not a hazard, and pre-remodel sampling belongs to a trained, accredited professional.
- ◆Never sand, scrape, saw or drill suspect material. Removal is a licensed abatement job, scheduled before demolition.
What the walls hide: wiring, pipe, plaster and seismic
Open a 1920s wall in Mission Hills and you usually find: knob-and-tube or cloth-wrapped wiring spliced to later circuits, and a panel that cannot carry a modern kitchen. Galvanized supply pipe narrowed with scale and cast iron drains cracked at the hubs. Wood lath and three-coat plaster, sometimes sound, sometimes held up by paint. Under the floor, short cripple walls, a sill never bolted to the concrete, and an unreinforced brick chimney.
These are reasons to budget honestly, not reasons to skip the remodel. Unreinforced masonry chimneys are the most vulnerable element of a wood-frame house in an earthquake, and California's Earthquake Brace and Bolt program exists because bolting the sill and bracing cripple walls is the known fix for pre-1980 raised-foundation houses. Plaster can usually be repaired rather than replaced, which preservation reviews prefer. The common contingency guidance in San Diego remodeling is 10 to 20 percent, and older homes sit toward the top.
How Swell approaches a Mission Hills remodel, and what it costs
Swell Contracting is a San Diego design-build general contractor, CSLB B license 970145, with an in-house flooring division, Tidal Flooring (CSLB C-15 1002910), and a cabinet shop. On a historic home that matters: the people drawing the kitchen, restoring the floor and building the cabinets are one team under one contract, so the floor patch is planned around the new island and the cabinet reveals are set to the original casings.
The free in-home visit starts with the parcel's historic status: designated, in a district, Register-listed, potentially historic, or simply 45-plus and undesignated. That decides whether the scope stays interior or exterior changes are drawn to the Standards and reviewed with Historical Resources staff first. Lead and asbestos testing are scheduled before demolition. The written estimate names materials, allowances, permits and what happens if framing, subfloor or plaster needs more than expected.
Swell's 2026 planning range for a San Diego kitchen remodel is $35,000 to $95,000, and for a bathroom $25,000 to $70,000 or more. A historic home usually lands higher within those ranges, for specific reasons: lead-safe containment, plaster repair instead of drywall, electrical and plumbing brought forward before finishes, floor repairs with matched reclaimed stock, custom casings to meet original trim, and historical review hours on designated homes. None of that is a fixed percentage; it is line by line in the estimate.
Swell in Mission Hills
Swell and Tidal Flooring have done restoration flooring and remodeling in Mission Hills for years: refinishing and repairing original red oak and Douglas fir in Craftsman bungalows and Spanish Revival homes, patching floors with reclaimed boards after wall removals, and remodeling kitchens and baths inside houses whose exteriors are protected. Several of those homes belong to San Diego architects, who tend to know exactly what they want kept.
