Owning a historic home in Mission Hills is a privilege, and it comes with unique responsibilities. You want to preserve the charm that first caught your eye while keeping your home safe, efficient, and market-ready. In this guide, you’ll learn how to approach windows, stucco, and clay tile roofs the right way, including what to fix, when to replace, and how to navigate San Diego approvals. Let’s dive in.
Why Mission Hills homes need special care
Mission Hills includes several designated historic areas where original craftsmanship and architectural details are part of the neighborhood’s identity. Local advocates highlight these districts and their significance to San Diego’s heritage. You can explore the area’s historic context through Mission Hills Heritage.
If your home is historic or older, exterior changes often require city review. San Diego follows the Secretary of the Interior’s Standards, which favor repair over replacement and look for compatible materials and design. Review the city’s process and start early with Historic Preservation Planning.
Some projects may qualify for the California Historical Building Code, which can offer alternative, preservation-friendly compliance paths. Discuss feasibility with city staff or a preservation architect and review the CHBC overview.
Historic windows: repair first
What you’re likely seeing
- Peeling paint, soft wood, or rot at sills and lower rails.
- Sashes that stick from paint build-up.
- Brittle glazing putty, cracked glass, or missing weatherstripping.
- A perception of poor energy performance compared to new units.
Best-practice fixes
Preservation guidance recommends repair first. You can reglaze, replace cords and weights, weatherstrip, and restore smooth operation for meaningful comfort gains without losing historic character. See the NPS guidance on practical upgrades in weatherization of historic windows and doors.
If replacement is unavoidable, match the original size, profile, and muntin pattern so street-facing elevations stay compatible with the home’s style. Expect to document existing conditions for review and coordinate early with the city’s Historic Preservation Planning team.
Lead-safe requirements
Most Mission Hills homes predate 1978. Window work that disturbs paint must follow the EPA’s Renovation, Repair and Painting Rule. Lead-safe rules apply for demolition, containment, and cleanup. Learn what certified firms must do through the EPA RRP program.
Stucco: match, patch, and manage moisture
How historic stucco differs
Historic stucco on Mission and Spanish Revival homes typically used cement, lime, and sand in three coats, often with distinctive textures and integral color. Matching composition, texture, and color is essential. Review best practices in NPS Preservation Brief 22 on historic stucco.
Common Mission Hills issues
- Hairline and settlement cracks, especially at corners or penetrations.
- Moisture-related damage from flashing failures or planters against walls.
- Deterioration at the wall base where drainage is poor.
Repair the right way
Diagnose the cause first, then patch rather than re-stucco wholesale whenever feasible. Use a skilled plasterer to match mix and texture, and follow proper curing conditions. NPS guidance cautions against harder cement mixes that can trap moisture in older walls. See recommendations in Preservation Brief 22.
Clay and Spanish tile roofs: preserve the system
What usually fails
Clay tiles themselves can last for decades. Most leaks come from underlayment failure, corroded flashings, slipped tiles, or deteriorated ridge mortar. Regular inspections and selective repairs help you avoid larger issues. Learn the preservation approach in Preservation Brief 30.
Repair and replacement strategy
Prioritize repair and selective tile replacement. If fasteners or underlayment have broadly failed, remove and re-lay using new underlayment and proper anchorage while reusing original tiles where possible. Hire roofers who specialize in clay tile conservation. Detailed guidance is in Preservation Brief 30.
Permits and code triggers
Roof renewals often require permits, and larger scope can trigger energy code and assembly requirements. If the property is historic, expect routing for historical review. Review submittal rules in San Diego’s Information Bulletin 123.
Permits, reviews, and incentives in San Diego
In San Diego, exterior work on historic or older homes is commonly reviewed for consistency with preservation standards. Engage Historical Resources staff early to confirm what needs approval and what documentation is required. Start with Historic Preservation Planning and the city’s Historical Resources program page.
Ask whether the California Historical Building Code may apply to your scope, and whether your property could qualify for Mills Act property tax relief in exchange for approved preservation. These conversations can shape your timeline and budget.
A simple project roadmap
- Document: Photograph windows, stucco cracks, tiles, and all flashing areas.
- Consult: Request a pre-submittal conversation with the city’s Historical Resources program to confirm review needs.
- Assess: Get surveys and proposals from contractors experienced with historic windows, stucco, and clay tile roofs.
- Design: If replacement is proposed, prepare measured drawings and justification. The NPS outlines helpful steps for window documentation before replacement.
- Permits and safety: Confirm EPA RRP compliance for any paint disturbance and secure required permits. See the EPA RRP program.
- Mock-ups: For stucco textures or window profiles, request mock-ups or sample boards to validate color, texture, and sightlines before full execution.
Choosing the right pros
- Prioritize preservation experience and familiarity with NPS briefs and local review.
- Verify EPA RRP certification for pre-1978 work involving paint.
- Ask for written scopes that separate repair, targeted replacement, and optional upgrades.
- Confirm warranties for underlayment and flashings, and whether original materials will be salvaged and reused when feasible.

FAQs
Should I repair or replace original wood windows in Mission Hills?
- Repair is usually preferred, and when paired with weatherstripping or storm solutions it can improve comfort while keeping historic character. Replace only when repair is impractical and match the original look.
Do hairline stucco cracks on a historic home mean I need full re-stucco?
- Not typically. Diagnose moisture and movement first, then patch with a matching mix and texture. Full re-stucco is reserved for widespread substrate failure.
How long do clay tile roofs on Mission Hills homes last?
- Clay tiles often last many decades. The usual issues are underlayment, flashings, and mortar, which can be repaired or renewed while reusing original tiles.
What permits or reviews apply to historic exterior work in San Diego?
- Exterior changes to designated or older homes are often routed to Historical Resources for review. Engage the city early to confirm requirements and documentation.
Are there lead-safe rules for window or paint work on older homes?
- Yes. Pre-1978 homes must follow EPA RRP rules for paint disturbance. Use certified firms that follow containment and cleanup requirements.
